USB(通用串行总线 )I/O 确实是名至实归,从20年前的标准制定大会开始这个产品就逐渐成为电子产品的当之无愧的霸主,无所不在。今天我们就来小叙一下USB的发展史,让我们从USB1.0开始吧。





USB1.0其实是用来给一开始的计算机外设准备的标准,但是的传输速率只有12Mb/s,紧凑的4路信号通道,可以支持热插拔功能,简单的试配软件即可轻松连接外加设备到主机上。连接器有两种不同的壳体,即A&B型。主机可以最多连接127个外设产品附件,很小的插入力可以保证连接器在窄小的空间仍可以使用。5v的低电压也可以驱动外接设备,尤其是紧凑的外形和耐用性使其在通用计算机外设和消费电子产品中得以广泛运用。
 
2001年,为了提高传输速率,USB2.0的诞生了!这也是印证了USB是一个拥有自我发展与完善基因的产品线。USB2.0可以向下兼容USB1.0,所用的界面都是一致的,速率提高到了480Mb/s. 但是运用范围已经远远超过了电脑外设的范畴,拓展到了游戏、存储、音视频产品,GPS,智能电话,数码影像等等领域。紧接着随着随身携带设备的普及,Mini 和Micro USB标准也就应运而是生,并且在事实上已经成为了随身携带设备接口的行业标准。
随着更高速率及大容量视频文件的传播,人们需要更快速度的接口产品这样以来就在2008年底,诞生了USB3.0.它的理论传输速度已经到达5Gb/s, 相当于10倍USB2.0的传输速率。在其他方面3.0也比2.0的要好,比如它的功耗只有后者的不到一半,这一特性对当今的移动设备市场是个很大的推动。传输电流从500毫安涨到900毫安,在原有线路上扩容5根线(2对差分信号1个地线),而且还是可以兼容USB2.0.
 
大家还记得A&B型是为了防止插错吗?一般A用在主机端,B用在外围设备中。USB3.0A可以完全向下兼容2.0但是USB3.0B是不可对接USB2.0母端的。
 
最具竞争力的产品来自于INTEL开发的thunderbolt连接器,目前已经广泛运用到APPLE的产品中,传输速率10Gb/s左右,目前已经有部分高端存储器采用这种方案。




为了让大家都享有10G的传输速率,USB论坛在2013年7月发布了USB3.1。还是采用标准A和Micro-B两种形式,900mA,5V,都没有变化。它解决了人们对普通USB产品有配接方向性的抱怨。









INTEL最近发布了Thunderbolt3.0产品,会兼容USB-C产品形式,并将拥有20Gb/s,将来目标是40Gb/s的产品。
有迹象表明Type C将替换目前所有其他的USB家庭成员的形式,今后3年多时间里,它将跟随人们的脚步,在高速率、用户友好性、低产品高度、耐用性等方面迅速宽展用户群体。

高速连接器确保数据中心的传输速度和效率

技术分享起点 发表了文章 • 0 个评论 • 2005 次浏览 • 2016-06-27 23:33 • 来自相关话题

在当今环境中,将数据访问外包(通过云)、同时持续支持带宽密集型应用(例如视频)的趋势使数据中心的重要性不断上升。 数据中心的管理人员希望尽可能提高数据中心架构的性能,甚至还深入到了连接器层面。为最大限度地提高数据中心的速度和效率,网络设备制造商在选择输入/输出 (I/O) 连接器时需要考虑五大关键标准 - 灵活性、成本、热管理、密度和电气性能。他们还必须在其设备的背板和电源连接器中优化这五大标准。
灵活性:
在选择各应用需要的电缆类型时,I/O 连接器应提供最大灵活性。例如,假设一个机架中所有的服务器都连接到一个位于机柜顶端的交换机。这些连接中绝大多数都相当短(通常不超过 3 米),因此使用铜质电缆则较为便宜。不过还有部分连接可能较长,需要使用光缆。制造商使用 SFP+、SFP28、QSFP+ 或 QSFP28 等插拔式连接器,数据中心运营商就能够选择合适的电缆来满足特定的需求
成本:
以行业趋势为基础,服务器的互连速度可达 1 Gbps,不过在某些更严苛的应用中,服务器现已支持 10 Gbps 的速度,甚至能达到 40 Gbps。虽然 40 Gbps 的连接已经存在多年,不过最近的趋势却是转向 25 Gbps 的解决方案。40 Gbps 的解决方案是通过 4 个分别为 10 Gbps 的数据通道完成的,因此制造商可以制造能够处理这些数据、打散分至 4 个通道然后将数据流重新集合为 40 Gbps 的“智能”设备。相反,25 Gbps 解决方案使用的是单一通道,因此其架空线路较低,更容易在服务器和交换机中实施。
热管理:
如果您使用的是铜质电缆组件,并将其替换为光纤模块,则信号会从电子信号转换为光信号,因此该模块现在正耗散功率。如果服务器上只有一两个互连,则这一点可能并不那么重要,但对于最多可存在 48 个互连的交换机,这就是一个重要因素。因为除了内部元件已产生的热能,现在设备又多了 48 个小型加热器,因此热管理变得极其重要。
使用光学互连后,制造商需要进行优化以获得新的动力,并需要能耗散更少功率的光纤模块以及有助于管理热负载的 I/O 连接器。
密度:
在交换机上,连接器必须尽可能小,以便提供最高的 I/O 密度,同时仍能够容纳带上述热负载的光纤模块。客户想要在一个 1RU 机箱中实现 24 个、48 个甚至更多的连接。行业对此的响应之一就是推出了新的 μQSFP 连接器(microQSFP)。现在,行业协会正在定义这一新的连接器标准,不仅要实现更高的密度,还有具备更出色的热管理,从而实现每个 1RU 机箱中最高 72 个端口。
电气性能:
虽然标准针对是的互连信道的整体性能(主机+ 连接器 + 电缆组件等的损耗),但是连接器制造商也可以通过增强信号完整性性能使其产品脱颖而出。例如,性能更佳的连接器或电缆组件可为设备设计师留有更多的设计裕度,以实现更长的信道段或更低的 PCB 材料成本。如今,交付的连接器带有多个 25 Gbps 对,适用于 25、100 和 400 Gbps 的应用,同时,带 50 Gbps 对的连接器也正在开发中或已上市。
 
由于设备需要支持更高的 I/O 性能密度,其背板也必须支持不断提高的聚合数据速率。利用支持 24 或 48 个 100 Gigabit 端口的线卡,背板连接器需要具有足够的容量。设备制造商需要下一代背板连接器,每差分线对能够支持 10 Gbps、25 Gbps、50 Gbps 以及更高的带宽。

事实上,背板是设备设计师考虑的第一要素。他们要将设备出售给大型的网络提供商,这些提供商希望设备能够使用尽可能长的时间。如果他们能够设计出一种背板机箱,不仅支持 10 Gbps 的第一代线卡,还支持可插入同一机箱的 25 Gbps 第二代线卡,以及随后的 50 Gbps、100 Gbps 线卡,那么这一设备就可以长期保留在数据中心,而需要更换的只有线卡而已。
电源结构:
电源输送架构也是设备开发工程师关注的因素。如前所述,更高的带宽和更高的 I/O 密度导致了更高的电源要求。连接器供应商以更高的密度和更低的电源连接器系统损耗(压降)将这些电源架构应用于汇流条、背板或电缆电源输送架构。

连接器是数据中心设备设计中的重要一环。通过使用以上标准,网络设备制造商可对其产品的效率和性能产生显著的影响。最新一代的电连接器使设备开发者能够满足这个高度连通的世界一项项具有挑战性的要求。

2毫米连接器改变通讯产业现状和未来

技术分享tianbian 发表了文章 • 0 个评论 • 1727 次浏览 • 2016-06-24 07:54 • 来自相关话题

The connector industry is very interesting, in part, because of exciting inventions developed by engineers – some of which have such an impact that the direction of the industry is changed.

In the late ‘80s, telecom OEMs were outgrowing the capabilities of the 0.100″-pitch connectors then available. They needed more signals to communicate to the backplane and were also moving to higher speeds that required more grounds, which further drove the need for more pins. The European telco industry was quite robust at the time, with large, growing companies in each country, including Ericsson, Siemens, Alcatel, and GPT. The US was dominated at the time by AT&T, which had just spun out Lucent. Nortel and NTT were also strong.

Telecom companies at that time were also connector manufacturers. Alcatel, Ericsson, GPT, Nortel, and AT&T all made their own connectors. Alcatel and Ericsson were using variants of the DIN 41612 standard (96-pin DIN connectors), but others were making complex multi-row connectors on 2.54mm pitch. Nortel made a four-row connector and AT&T made an exotic eight-row 0.125″-pitch connector that straddled the daughtercard with four rows of surface-mount leads on each side. They called this eight-row monster Fastek. You can imagine the manufacturers of telecom equipment were feeling really constrained by the limitations of these connectors and were quite anxious to find a new interconnect solution that would enable more pins per inch on the backplane, more cards per shelf, and lower costs.

AT&T had internal CAD (computer-aided design) standards around the Fastek system that basically allowed design engineers to design boards and electronic circuits, all using a standard backplane connector and backplane grid. AT&T had a unique manufacturing process for backplanes where it inserted individual pins into the backplane with fully automated machines. This process eliminated in-process inventory except raw pins on reels and backplane PCBs. To make system A, engineers programmed the machine to insert pins exactly where needed. They could have multiple pin lengths inserted to facilitate sequenced mating in a much easier way than that of competitors. The flexibility was quite impressive. A backplane-populating machine could make sophisticated backplanes for large switches today and for a simple access backplane tomorrow. AT&T had a plant in Richmond, Va., that utilized more than 10 of these stitching machines, which produced hundreds of backplanes every day. AT&T was so integrated that it made its own connectors, pins, backplanes, and daughtercards. Those were the days!

Both AMP and Berg were working on this challenge simultaneously, and the development centers for both companies happened to be a few blocks apart in s’Hertogenbosch, Netherlands, known to the Dutch as denBosch (the Duke’s woods). There must have been innovation in the drinking water since both companies developed industry-changing designs.

Berg assembled a team to address this opportunity: John Harding, telecom industry manager, shuttled between the major customers gathering requirements, and Hans van Woensel, product engineer at Berg, was assigned the task of inventing a new connector that could double the pin density without sacrificing on reliability or cost. As the concept developed, Harding revisited each of the customers to get their reactions. To address the broadest range of opportunities, Berg decided to develop a system composed of 12mm-long blocks with four rows of contacts on a 2mm x 2mm mating grid. By stacking these modules side by side, Berg was able to provide up to 456 mating pins on a 233mm-tall Eurocard form factor, replacing two 96-pin DIN 41612 connectors then in use.

Berg was able to quickly prototype this concept because the contacts and housings could be tooled quickly and inexpensively. Berg also developed a small stitching module that inserted one contact at a time at high speed. This flexible stitching module enabled them to produce production-quality parts very quickly and to expand capacity by adding as many additional stitching modules as necessary. These modules could stitch receptacles today and headers tomorrow with changeover tooling, raising the bar in terms of time to market and quality of initial parts. This family became the Metral 2mm backplane connector system.

Ericsson was especially forward-looking for the time. Its team envisioned its facility populating daughtercards and backplanes with fully automated machines fed by 12mm connector blocks in tube packaging. They used robot-like pick-and-place machines to place power, signal, and guidance modules as needed for any daughtercard that came along.

Berg also developed power and guidance modules that could be placed in convenient locations to optimize the connector configuration for each card. The team was able to take initial Metral parts to make a prototype that met the requirements of the IEEE 896 working group developing the Futurebus+ standard.

A constant 2mm contact pitch allows many efficient manufacturing techniques. Contacts on a constant 2mm pitch can be mass-inserted into housings continuously, maximizing use of the contacts on strip and minimizing the number of insertion steps. Contacts in right-angle daughtercard connectors can be inserted then bent, a rather efficient manufacturing process. Berg chose to stitch contacts and created standard high-speed stitching machines that could make every variant at high speed and low cost. The cost reduction relative to the 96-pin DIN connectors was substantial – more than 50%. Much less material was used, including metal, plastic, and gold plating. The manufacturing process was also optimized for efficiency.

The telecom customers were delighted. They could see significant cost reductions for their future designs, as well as density and performance improvements. They rapidly endorsed this approach and changed their internal card-cage standards to take advantage. AT&T, moving from 0.125″ connectors to 2mm- (0.79″-) pitch connectors, saw so much of an advantage that they created a new AT&T standard card-cage architecture.

The Metral connector was introduced to the IEEE 896 Futurebus standards committee and won the standard against six-row 0.100″ connector designs. At the time, Augat presented a six-row straddle-mount connector on 0.100″ centers and AMP proposed a right-angle six-row solder-to-board connector. Berg proposed a mix of 4×12 signal modules and six-pin power blocks that was able to meet all of the requirements of the Futurebus specification. Berg partnered with AT&T and Ericsson to present the Metral connector. Part of the deal was that other connector manufacturers were then able to tool Metral connectors royalty-free, a key business decision. This created enough momentum to win the standard and quickly proliferate the number of Metral producers, making this connector one of the dominant standards in the telecom industry. Metral has been tooled by Berg, Molex, AT&T, Ericsson, ITT Cannon, SOURIAU, CECO, and several other suppliers.

A couple of ironies evolved from this saga. First, after its approval by IEEE, Futurebus never achieved commercial success as a standard. It was a seven-legged calf, a term for a standard that incorporates so many features and variants that it becomes totally un-optimized for any of them. The connector, however, was broadly adopted, especially for telecom applications at Ericsson, Alcatel, GPT, and AT&T (that later spun off Lucent). The simplicity and modularity of the connector, and the fact that it was tooled by so many suppliers, made it one of the most cost-effective backplane connectors ever tooled. It is still broadly used today, mostly in telecom access boxes.

The second irony is that, as the telecom industry imploded in the late ‘90s, the connector companies consolidated. Berg acquired the connector operations of Nortel, Ericsson, AT&T, and Alcatel. FCI, who had earlier acquired SOURIAU, acquired Berg. The net result was that FCI acquired nearly all of the Metral capacity.
 
Special Metral modules have evolved, including high-speed modules with internal shielding, larger modules, cable solutions, and even RF. CECO, a California molding house with special expertise in building tools for long connectors, developed a very nice business in making a better connector than the commodity producers. The FX-2 product line included long “monoblock” housings, dual-beam beryllium copper contacts (lower mating force, higher conductivity), and integrated guide pins to fit customer requirements exactly. IBM, in particular, specified the CECO 2mm FX-2 connectors for its mid-range servers.

The connector industry is very interesting, in part, because of exciting inventions developed by engineers – some of which have such an impact that the direction of the industry is changed.

In the late ‘80s, telecom OEMs were outgrowing the capabilities of the 0.100″-pitch connectors then available. They needed more signals to communicate to the backplane and were also moving to higher speeds that required more grounds, which further drove the need for more pins. The European telco industry was quite robust at the time, with large, growing companies in each country, including Ericsson, Siemens, Alcatel, and GPT. The US was dominated at the time by AT&T, which had just spun out Lucent. Nortel and NTT were also strong.

Telecom companies at that time were also connector manufacturers. Alcatel, Ericsson, GPT, Nortel, and AT&T all made their own connectors. Alcatel and Ericsson were using variants of the DIN 41612 standard (96-pin DIN connectors), but others were making complex multi-row connectors on 2.54mm pitch. Nortel made a four-row connector and AT&T made an exotic eight-row 0.125″-pitch connector that straddled the daughtercard with four rows of surface-mount leads on each side. They called this eight-row monster Fastek. You can imagine the manufacturers of telecom equipment were feeling really constrained by the limitations of these connectors and were quite anxious to find a new interconnect solution that would enable more pins per inch on the backplane, more cards per shelf, and lower costs.

AT&T had internal CAD (computer-aided design) standards around the Fastek system that basically allowed design engineers to design boards and electronic circuits, all using a standard backplane connector and backplane grid. AT&T had a unique manufacturing process for backplanes where it inserted individual pins into the backplane with fully automated machines. This process eliminated in-process inventory except raw pins on reels and backplane PCBs. To make system A, engineers programmed the machine to insert pins exactly where needed. They could have multiple pin lengths inserted to facilitate sequenced mating in a much easier way than that of competitors. The flexibility was quite impressive. A backplane-populating machine could make sophisticated backplanes for large switches today and for a simple access backplane tomorrow. AT&T had a plant in Richmond, Va., that utilized more than 10 of these stitching machines, which produced hundreds of backplanes every day. AT&T was so integrated that it made its own connectors, pins, backplanes, and daughtercards. Those were the days!

Connectors for Non-highway vehicles application 农机与建机连接器

Seasoned operators of commercial vehicles will say they can sense how their vehicles are performing based on the sounds and vibrations the vehicles produce. Today, the latest commercial vehicles can do that on their own via sophisticated communications systems that monitor performance, position the vehicle,schedule needed maintenance, communicate with accessory equipment,and even help drive the vehicle, among other functions.These communications systems require myriad electronic components.

There are a host of vehicles that require complex interconnect systems,such as agricultural vehicles that precisely monitor sprayer output; commercial buses with Wi-Fi networks, plug-and-play entertainment systems for passengers, and multiple security and driver-assist camera systems;and emergency vehicles that process critical data from patient monitoring equipment. For purposes here, Molex focuses on two critical heavyduty applications: agricultural and construction/mining vehicles.
 
Agricultural vehicles with 24/7 communications systems offer important competitive advantages. For example, communications modules in tractors and implements ensure that croplands are precisely planted and harvested with greater efficiency. These modules can regulate distribution of fertilizer and seed, which improves cultivation and crop yields.

Also, if there is a problem with a tractor, combine, or implement, the dealer or the operator can be automatically alerted via wireless communication,depending on the severity of the issue. Since machine uptime is vital, this application can improve farming productivity.Communications systems are obviously a key part of autonomous agricultural vehicles, which free farmers to perform other tasks. Some of these
systems coordinate multiple autonomous vehicles, such as when a tractor grain hauler receives grain from a combine that is harvesting a field of crops.

For construction and mining vehicles, 24/7 communications systems have an added importance. Unlike, agricultural vehicles, which are used heavily for certain periods and then housed, many construction and mining vehicles operate nearly 24/7 for indefinite periods, making maintenance diagnostics and communications systems that much more critical.




Also, multiple cameras and sensors are needed on both agricultural and construction and mining vehicles to ensure safe operation in often dangerous work environments.These communications systems typically include devices such as video cameras and displays, along with complex sensor and control systems that produce large volumes of high-speed data that assist operators with crucial tasks.

Free-flowing data
With more data flowing through commercial vehicles than ever before, communications systems require highspeed connectors and cables that can transmit 5 to 10Gbps of data to transfer images and video. While some of these connectors handle data only, the trend is to use hybrid connectors that can handle both data and power,some of which can be specified with two or four lines of signal and power.
 
One major challenge with hybrid connectors is the electromagnetic interference (EMI) generated when power is transmitted through the connectors. As a result, connectors and cables in these systems must be shielded to protect them from EMI and crosstalk. Common shielding methods include individual shielding via aluminum foil for each twisted pair; foil shielding, braided shield or braiding with foil across all of the pairs; and individual shielding via foil between the twisted pair sets combined with an outer foil or braided shielding.
 
While much of this technology is not new, its application to the commercial vehicle industry is more recent.
Manufacturers are now adopting various high-speed protocols that have been used by other industries for
years. The difference is that communications systems for heavy-duty vehicles must be ruggedized,particularly in terms of latching and sealing.That means communications networks in commercial vehicles must provide all the benefits of high-speed networks found in automotive vehicles as well as greater protection from increased vibration, shock, and fluid ingress.Plus, they must accomplish this while being housed in more
complex and denser packages. As a result, high-speed interconnect systems have been modified to meet the challenges emerging from the commercial vehicle industry.





Networking evolution
Typical USB interconnect systems are based on passive,unlatched, plug-in connectors, but automotive USB applications must be latched. As a result, unsealed USB connector systems for automotive applications include shrouds and latches that meet USCAR standards.Compared to automotive applications, however,
heavy-duty, off-highway applications typically require sealed systems with additional protection against increased vibration, shock, and fluid ingress. For that reason,interconnect systems for commercial vehicles require fully protected perimeter seals and wire seals rated to IP67 and IP69K for use in off-highway environments.
 
Sometimes, an even more ruggedized product is required for use on vehicle exteriors. These metalized interconnect systems, which are sometimes available in high-speed CAT 6 versions, are typically sealed, threaded,and have metalized shells and push/pull locks. Some versions can even withstand a 300-lb (1.33-kN) pull force and are designed to withstand the driver of a vehicle standing on the cable when entering or exiting the cab.
 
Likewise, sealing technology that has been tested and approved in other industries can be used in electronic
components for commercial vehicles. That includes different levels of sealing proficiency, from protection against dust or light sprays to protection from a stream of water from a hose to being able to be fully immersed in water. When protecting components from vibration in commercial vehicles, it helps to have multiple contact points within the connector system.
 
Commercial vehicle manufacturers have traditionally used vibration-resistant pin and socket connectors because they provide multiple points of contact for the socket around a cylindrical pin. Their counterparts in the automotive industry, however, have mostly transitioned to less-expensive blade-and-receptacle connectors, which also offer multiple contacts. Commercial vehicle manufacturers are now embracing this trend.
 
Traditionally, blade-and-receptacle connectors were not appropriate for high-vibration environments, but newer designs have been refined to the point where, based on the contact’s geometry, they can withstand up to 20g. For example, the MX123 sealed connection system from Molex is basically a blade-and-receptacle system. It is designed for high-vibration, under-thehood powertrain applications while still maintaining a small packaging size.
 
Changing sensors and standards
Another key component trend in commercial vehicles is the growing use of sensors. The challenge will be determining how information is collected from those sensors and how it is provided to a screen or interface
in a manner that doesn’t overwhelm the operator.
 
Both the types of sensors and their sheer numbers are increasing, including sensors for lighting, air/tire pressure, current, and positioning, along with gas, brake, and hydraulic fluid levels. Sensors specific to agricultural vehicles include hopper level, application-rate, and high-rate seed sensors.

Also, the manner in which sensors and connectors are specified in communication systems is evolving. Agricultural vehicle manufacturers tend to follow ISO Bus communications standards such as ISO 11783, and construction and mining vehicle manufacturers tend to follow SAE standards. In addition, commercial vehicle manufacturers also use their internal proprietary specifications for higher-level communications, which make vehicles and equipment made by the same manufacturer interoperable.
 
However, this also means they may not effectively communicate with equipment made by other manufacturers. While these proprietary specifications and requirements are a problem for customers
using vehicles from different manufacturers, it allows individual manufacturers to differentiate their products and develop a competitive edge for their vehicles. For example, many manufacturers of connectors for commercial vehicles work with the SAE J2030 specification, which encompasses connectors between two cables or between a cable and an electrical component and focuses on the connectors external to the electrical component.The specification describes the minimum criteria needed to establish that a connector will work in a ruggedized application.





When developing a connector for commercial vehicles, Molex will typically test it to J2030 because that provides the company with a“calling card” when it wants to qualify the part with a customer, such as
Caterpillar or John Deere. Customers may accept a part based on it passing J2030, then test it further to determine if it meets their own internal specifications. Some manufacturers share those internal specifications
with suppliers and some do not.Managing the ‘pizza box’One thing to keep in mind when designing a high-speed and high-power interconnect system for a commercial vehicle is that it is part of an overall vehicle architecture involving high-speed communications and high-power electrification systems. For example, in addition to standard body/chassis, safety, powertrain, and infotainment connectors, an emerging trend is toward electric drives and accessory connector systems for high-voltage power applications.

A large number of wires and connections are routed to control modules that can be the size of a pizza box. Just trying to get the mixture of straight and right-angle entry wires routed through the vehicle is an ever-increasing challenge. As a result, smaller, lighter, and more flexible connectors that allow easier cable exits are required. For example, a 1.5-mm terminal may need to be downsized to 1.2-mm, and 18- or 20-gauge wire replaced with 22-gauge wire. Likewise, smaller insulation diameters and lighter weight aluminum wire may need to be used instead of copper wire.

Another option might be to move to single-mode glass or plastic fiber optic cable. One fiber optic line can replace multiple copper wires. Also, some manufacturers are using flat cabling because it can be mounted flat to the sides of the vehicle and does not have to be bundled like traditional wiring (a bundle of wires creates a circular cross section with a larger diameter whereas flat cable does not).

Finally, a communications network for a heavy-duty vehicle must be integrated based on system speed requirements, number of required ports, desired protocols,cable design, cable shielding levels, and connector attachments.That means connector suppliers must also be experts in systems design, preferably working as a team with the customers on initial communication systems designs. Selecting the right interconnect scheme, including overall resistance and shielding of the system, can be critical to creating 24/7 communications systems that help control heavy-duty vehicles now and in the future.

Seasoned operators of commercial vehicles will say they can sense how their vehicles are performing based on the sounds and vibrations the vehicles produce. Today, the latest commercial vehicles can do that on their own via sophisticated communications systems that monitor performance, position the vehicle,schedule needed maintenance, communicate with accessory equipment,and even help drive the vehicle, among other functions.These communications systems require myriad electronic components.

There are a host of vehicles that require complex interconnect systems,such as agricultural vehicles that precisely monitor sprayer output; commercial buses with Wi-Fi networks, plug-and-play entertainment systems for passengers, and multiple security and driver-assist camera systems;and emergency vehicles that process critical data from patient monitoring equipment. For purposes here, Molex focuses on two critical heavyduty applications: agricultural and construction/mining vehicles.
 
Agricultural vehicles with 24/7 communications systems offer important competitive advantages. For example, communications modules in tractors and implements ensure that croplands are precisely planted and harvested with greater efficiency. These modules can regulate distribution of fertilizer and seed, which improves cultivation and crop yields.

Also, if there is a problem with a tractor, combine, or implement, the dealer or the operator can be automatically alerted via wireless communication,depending on the severity of the issue. Since machine uptime is vital, this application can improve farming productivity.Communications systems are obviously a key part of autonomous agricultural vehicles, which free farmers to perform other tasks. Some of these
systems coordinate multiple autonomous vehicles, such as when a tractor grain hauler receives grain from a combine that is harvesting a field of crops.

For construction and mining vehicles, 24/7 communications systems have an added importance. Unlike, agricultural vehicles, which are used heavily for certain periods and then housed, many construction and mining vehicles operate nearly 24/7 for indefinite periods, making maintenance diagnostics and communications systems that much more critical.

Also, multiple cameras and sensors are needed on both agricultural and construction and mining vehicles to ensure safe operation in often dangerous work environments.These communications systems typically include devices such as video cameras and displays, along with complex sensor and control systems that produce large volumes of high-speed data that assist operators with crucial tasks.

Free-flowing data
With more data flowing through commercial vehicles than ever before, communications systems require highspeed connectors and cables that can transmit 5 to 10Gbps of data to transfer images and video. While some of these connectors handle data only, the trend is to use hybrid connectors that can handle both data and power,some of which can be specified with two or four lines of signal and power.
 
One major challenge with hybrid connectors is the electromagnetic interference (EMI) generated when power is transmitted through the connectors. As a result, connectors and cables in these systems must be shielded to protect them from EMI and crosstalk. Common shielding methods include individual shielding via aluminum foil for each twisted pair; foil shielding, braided shield or braiding with foil across all of the pairs; and individual shielding via foil between the twisted pair sets combined with an outer foil or braided shielding.
 
While much of this technology is not new, its application to the commercial vehicle industry is more recent.
Manufacturers are now adopting various high-speed protocols that have been used by other industries for
years. The difference is that communications systems for heavy-duty vehicles must be ruggedized,particularly in terms of latching and sealing.That means communications networks in commercial vehicles must provide all the benefits of high-speed networks found in automotive vehicles as well as greater protection from increased vibration, shock, and fluid ingress.Plus, they must accomplish this while being housed in more
complex and denser packages. As a result, high-speed interconnect systems have been modified to meet the challenges emerging from the commercial vehicle industry.

Networking evolution
Typical USB interconnect systems are based on passive,unlatched, plug-in connectors, but automotive USB applications must be latched. As a result, unsealed USB connector systems for automotive applications include shrouds and latches that meet USCAR standards.Compared to automotive applications, however,
heavy-duty, off-highway applications typically require sealed systems with additional protection against increased vibration, shock, and fluid ingress. For that reason,interconnect systems for commercial vehicles require fully protected perimeter seals and wire seals rated to IP67 and IP69K for use in off-highway environments.
 
Sometimes, an even more ruggedized product is required for use on vehicle exteriors. These metalized interconnect systems, which are sometimes available in high-speed CAT 6 versions, are typically sealed, threaded,and have metalized shells and push/pull locks. Some versions can even withstand a 300-lb (1.33-kN) pull force and are designed to withstand the driver of a vehicle standing on the cable when entering or exiting the cab.
 
Likewise, sealing technology that has been tested and approved in other industries can be used in electronic
components for commercial vehicles. That includes different levels of sealing proficiency, from protection against dust or light sprays to protection from a stream of water from a hose to being able to be fully immersed in water. When protecting components from vibration in commercial vehicles, it helps to have multiple contact points within the connector system.
