C、护套之间可以相互挂接
③、带卡锁机构的接插件，其优点是使线与线间或线与电气件间的连接更为牢固，防止松动。一般用在发动机上、雨刮电机等颠簸震动的环境 。卡锁机构形式的插接件一般有如下几种。

④、带压线盖的接插件，它可保证插接件插入的端子尾部压接的导线不在插接件根部时出现不必要的晃动，减少插接件震动对导线的剪切力，提高线束的品质

2）、接插件的结构形式
①、防水接插件要达到防水、防尘的效果。一般可分为整体密封和单孔密封，后者较为常用；采用的密封材料可为：橡胶密封塞和注胶密封，前者较为常用。
根据工作环境和空间大小制定以下包扎设计方案。

4、线间接插件的选择
根据附表1以及上述的接插件选择原则，对线间接插件进行选型。见附表2。
其中需要注意的是，每条线束的接插件均需要至少预留2至3个空脚位便于功能扩展。
5、与用电设备接插件的选择
①、要求线束端（A端）与用电器端（B端）的接插件必须采用同一供应商、同一对接型号的产品。
②、若B端为固定端，则需要对A、B端的连接进行试验验证，编入线束DVP计划。

④、避免在同一对接区域使用同一种护套，若无法避免，则需通过不同颜色加以区分。
⑤、基于汽车外观的整体协调性，在发动机舱中应优先选用黑色或深色的护套。
⑥、为减少线束对接用护套的种类和数量，优先选用混合型件，使装配固定方便，见下图。
⑦、车门线束与车身线束对接时，其最好选用带卡锁机构的护套，保证在车门频繁的开
根据实际情况在塑料中添加阻燃或增强材料，以达到增强或阻燃的目的，如添加
玻璃纤维增强等。

3、端子选取原则
插接件用的端子主要是由黄铜和青铜构成（黄铜的硬度比青铜的硬度稍低），其中黄铜占的比重较大。另外，可根据不同的需求选择不同的镀层。对于要求性能较高的安全气囊、ABS、ECU等用的端子插接件，应优先选用镀金件以保证安全可靠性，但出于成本考虑，在满足性能要求的前提下可选择局部镀金处理。
③、若用电设备供应商提供的B端接插件不满足性能要求，则线束端有权要求其重新选择，或由线束端指定。

⑧、为节约成本，安全等级较低的用电设备尽量选择满足其性能要求的国产件；驾驶室
内除地板外可选择非防水型护套；在不同区域采用同种型号的护套，减少品种。
