擴大一個堅實的基礎(chǔ)：“加固”的下一代嵌入式計算應(yīng)用的連接器

　　更多。這是“推動性能包絡(luò)”的本質(zhì)，對于嵌入式計算機系統(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處理日益復(fù)雜的信號情報和網(wǎng)絡(luò)戰(zhàn)。這，反過來，不僅需要能夠處理高數(shù)據(jù)速率的連接，而且還提供增強的強度在惡劣的環(huán)境中提供可靠的操作。

　　即使設(shè)計師追求更高的處理負荷和更堅固的組件，其他兩個趨勢影響連接器的設(shè)計。首先是要解決交換大小，重量和功耗創(chuàng)建更小，更輕，更強大的系統(tǒng)。在高性能飛機，無論是載人或無人駕駛，空間總是在一個溢價，重量有直接關(guān)系的飛行時間和有效載荷，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.
