2.2.1 RJ45模块(modular)RJ45模块是布线系统中连接器的一种，连接器由插头和插座组成。

这两种元件组成的连接器连接于导线之间，以实现导线的电气连续性。

RJ45模块就是连接器中的最重要的一种插座。

RJ是Registered Jack的缩写，意思是“注册的插座”。

在FCC（美国联邦通信委员会标准和规章）中的定义是，RJ是描述公用电信网络的接口，常用的有RJ-11和RJ-45，计算机网络的RJ-45是标准8位模块化接口的俗称。

在以往的四类、五类、超五类，包括刚刚出台的六类布线中，采用的都是RJ 型接口。

在七类布线系统中，将允许“非-RJ型”的接口，如2002年7月30日，西蒙公司开发的TERA七类连接件被正式选为“非-RJ”型七类标准工业接口的标准模式。

TERA连接件的传输带宽高达1.2GHz，超过目前正在制定中的600MHz七类标准传输带宽。

网络通信领域常见的有四种基本RJ模块插座，每一种基本的插座可以连接不同构造的RJ。

例如，一个6芯插座可以连接RJ11（1对）、RJ14（2对）或RJ25C（3对）；一个8芯插座可以连接RJ61C（4对）和RJ48C。

8芯（Keyed）可连接RJ45S、RJ46S和RJ47S。

RJ45插座与RJ45连接头（水晶头）是综合布线系统中的基本连接器，我们在后面还会详细介绍RJ45连接头（水晶头）。

RJ45模块的核心是模块化插孔。

镀金的导线或插座孔可维持与模块化插头弹片间稳定而可靠的电连接。

由于弹片与插孔间的磨擦作用，电接触随插头的插入而得到进一步加强。

插孔主体设计采用了整体锁定机制，这样当模块化插头（如RJ45插头）插入时，插头和插孔的界面处可产生最大的拉拔强度。

RJ45模块上的接线块通过线槽来连接双绞线，锁定弹片可以在面板等信息出口装置上固定RJ45模块。

图2-20分别是RJ45模块的正视图、侧视图、立体图。

rj45母座封装标准
RJ45母座封装标准如下：
1.RJ45接口作为最基本的网络接口之一有两种形式，对于千兆网口
有4条线，两对差分线；对于千兆网口有4对差分线，RJ45水晶头是有8个凹槽和8个触点（8p8c）的接头，RJ45接口分为集成网络变压器和非集成网络变压器两种。

2.RJ11水晶头一般都是4芯的，常用来连接电话和调制解调器。

需
要注意的是，RJ11通常指的是6个位置（6针）模块化的插孔或插头，但是只有4针被用到，RJ11通常只有6个凹槽和4个触点（6p4c）的接头。

3.RJ45水晶头接线时有两种线序标准：T-568A和T-568B。

通过采用
不同的标准，最后制作成的网线有直通型和交叉型两种。

有的变压器中心抽头接到地，而且接电源时，电源值又可以不一样，3.3V、
2.5V、1.8V都有。

有些接地。
