连接器产品通用详细教程

　　连接器的教程

　　连接器可能不是电路中最复杂的部分，但它们无疑是最重要的部件之一。电路可以用几种不同的方式来考虑。大多数工程师可能看到电路的第一种方法是理论方面，可以在纸上表示。虽然这很重要，当然没有一个电路在没有经过深思熟虑的情况下也能正常工作，但这不是整个画面。电路是指进入一个设备或产品，是为了执行某种功能。通常这些产品可能非常大，像飞机或火车，当然不能安装在大型电路板上，它们可能根本就没有电路板。因此，连接器被认为是连接不一定在同一物理板上的电路的快速有效的方法，它们是通往电子公路的旁路。

　　市场上有几种不同类型的连接器，所有这些都服务于同一目的，但以不同的方式实现。有些是用来在汽车应用中，振动是一个问题，而另一些是要在外面的一个静态的，但风化的环境，名单永远不会结束。连接器有助于缩短制造时间，工人焊接几个连接所需的时间要比将一个连接器插入另一个连接器的时间长得多。希望这篇文章能对一般的连接器有所启发，以及在某个应用程序中应该使用哪个连接器。

　　Rectangular connectors

　　The term “rectangular connector” refers to the shape of the actual connector. It means that this connector housing will be rectangular in shape. These are often found on PCB boards because they are easy to use for manufacturing. A board will typically have either a through hole or surface-mounted male header that a female socket can fit onto， this is a good way to connect wires to a board. The female connector would have sockets with wires crimped onto them which would be connected to something else. An example of this would be the B2B-XH-A（LF）（SN）， which is the male header， and the XHP-2， which is the female housing that would mate with the header. These products are from JST Sales America Inc. and will not work as-is. The XHP-2 is only a plastic housing， there are no sockets inside of this connector， so there are also no wires coming out of this connector. The sockets are proprietary accessories that are specific to the housing. While several contacts are very similar， it is always recommended to use the proper contacts that are made for the particular connector housing to ensure the connector will work. On the Digi-Key page for XHP-2 there is a section towards the bottom of the page that shows the sockets as an “Associated Product” （Figure 1）.
