本文件规定了适用于符合EN 3155-002要求的连接元件中使用的T级A型双压接凹形电触点045所需的特性、试验和工具。应与EN 3155-001一起使用。相关的公触点在EN 3155-044中定义。双压接触头有一个筒体，用于将电缆的导体和护套压接在两个位置，一个压接在导体上，另一个压接在护套上。这样可以保护导体不受机械强度的影响。

This document specifies the required characteristics, tests and tooling applicable to female electrical contacts 045, type A, double crimping, class T, used in elements of connection according to EN 3155-002. It shall be used together with EN 3155-001. The associated male contact is defined in EN 3155-044. Double crimping contact has a barrel which is design to crimp conductor and jacket of cable in two locations, one on the conductor and the other on the jacket. This way protect the conductor from mechanical strengths.
