擴(kuò)大一個(gè)堅(jiān)實(shí)的基礎(chǔ)：“加固”的下一代嵌入式計(jì)算應(yīng)用的連接器

　　擴(kuò)大一個(gè)堅(jiān)實(shí)的基礎(chǔ)：“加固”的下一代嵌入式計(jì)算應(yīng)用的連接器

　　更多。這是“推動(dòng)性能包絡(luò)”的本質(zhì)，對(duì)于嵌入式計(jì)算機(jī)系統(tǒng)在軍事和航空航天領(lǐng)域的應(yīng)用，它意味著更高的速度處理來(lái)處理日益復(fù)雜的信號(hào)情報(bào)和網(wǎng)絡(luò)戰(zhàn)。這，反過(guò)來(lái)，不僅需要能夠處理高數(shù)據(jù)速率的連接，而且還提供增強(qiáng)的強(qiáng)度在惡劣的環(huán)境中提供可靠的操作。

　　即使設(shè)計(jì)師追求更高的處理負(fù)荷和更堅(jiān)固的組件，其他兩個(gè)趨勢(shì)影響連接器的設(shè)計(jì)。首先是要解決交換大小，重量和功耗創(chuàng)建更小，更輕，更強(qiáng)大的系統(tǒng)。在高性能飛機(jī)，無(wú)論是載人或無(wú)人駕駛，空間總是在一個(gè)溢價(jià)，重量有直接關(guān)系的飛行時(shí)間和有效載荷，高效的功率分配有助于更小的發(fā)電組件。因此，系統(tǒng)設(shè)計(jì)者癡迷于交換并不奇怪。

　　The other important trend is the use of commercial off-the-shelf （COTS） components—ensuring product availability when you need it. Even a new design can be COTS-based by using well-established building blocks and field-proven technology.

　　New levels of connector ruggedization can take two forms： （1） an entirely new connector or （2） an upgrade to an existing connector. Option 1 gives the most freedom， but at the expense of legacy product designs and standards. Option 2 allows backwards compatibility with existing connectors and board designs.

　　The TE Fortis Zd connector is an example of Option 1. Even though the connector is relatively new， it has its roots in COTS. This connector， designed around military pedigree MIL-DTL-55302 Mini-Box contacts， is a new design that offers higher speeds （12+ Gb/s） and high levels of ruggedness. The connector has been considered for several standards， and finds applications where performance trumps meeting a standard.

　　An example of Option 2 is seen in TE’s MULTIGIG RT 2 connector， which is discussed in detail below.
