扩大一个坚实的基础:“加固”的下一代嵌入式计算应用的连接器
更多。这是“推动性能包络”的本质,对于嵌入式计算机系统在军事和航空航天领域的应用,它意味着更高的速度处理来处理日益复杂的信号情报和网络战。这,反过来,不仅需要能够处理高数据速率的连接,而且还提供增强的强度在恶劣的环境中提供可靠的操作。
即使设计师追求更高的处理负荷和更坚固的组件,其他两个趋势影响连接器的设计。首先是要解决交换大小,重量和功耗创建更小,更轻,更强大的系统。在高性能飞机,无论是载人或无人驾驶,空间总是在一个溢价,重量有直接关系的飞行时间和有效载荷,高效的功率分配有助于更小的发电组件。因此,系统设计者痴迷于交换并不奇怪。
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.
