连接器几乎总是由两个交配的两半组成。与插座配合的插头。连接器制造商遇到很多麻烦，以确保连接器正确配合，并且不能不正确地交配。本文介绍了使用的一些技术。
飞行电缆连接通常是最简单的。用户可以掌握他或她的手中的两个交配零件。看看形状；他们如何在一起应该很明显。通常，这是通过仅用一种方式配合塑料形状来完成的。闩锁进一步有助于方向，并确保连接器在正常使用中保持交配，即使误用了。

当连接器的一侧固定在机柜上，与电缆交配时，通常可以更容易，因为应该如何对连接器进行匹配。从照明设备，到较大的组件中的电池和组件的各种电气设备的接线通常可以找到这种连接。通常，这有助于最终用户组装。
If both mating sides of the connector are fixed into larger boxes, the mating issues become much more serious. Imagine a battery that is slid into your leaf blower, for example. Now the surfaces that capture the mating parts become much more important.
First, it must be obvious in orientation. I frequently see rectangular or triangular elements that are easily oriented before mating.
Shape of the mating parts makes it obvious how this is properly engaged. Note that the metal contacts are all protected by plastic features.
Once the plastic is engaged, the interior of the mating connector will center the plug so that it can easily find the mating contacts. This works well if the mating contact has a generous lead in.
不幸的是，并非所有交配系统都能负担得起如此宽敞的交配表面，因为它们太小了。减轻此问题的技术之一是，在触点伴侣之前将浮动连接器安装在金属工程上。
这种解决方案通常是在电源滑入电缆已经位于底盘中的浮动盲交配中的系统中，最常使用的解决方案。
Another way of facilitating blind mating is to use a guide pin rigidly mounted on a panel that engages with a guide receptacle on the part that slides into the box. This is an excellent way of mating modular units into a chassis, like power supplies, disk drives, and the like. In this case, the guide pins provide initial gathering, then the plastic housings provide a further gathering, then the windows on the mating receptacle gather the mating pins; all before the contacts come into play. By using a combination of all of these gathering techniques, a well designed connector system can provide failsafe mating all the time, ensuring long life of the interconnect and a happy customer.
It is quite important that you consider the end user as you design equipment where elements will be plugged in the field. You are wise to consider how a clumsy end user might try to plug incorrectly and assure that the mating system can tolerate the mismating and make it easy and obvious how to mate properly.
