本发明涉及一种双金属片（1）和作为支撑件（5）在电流断开装置的双金属条带的一部分的装配装置，所述双金属片（1）被电通过的第一端连接 （1a）所述自由端在第一输入端子（3）处和另一端处，所述双金属片在所述第二所谓输出连接范围（4）处通过所述自由端固定到所述支撑件（5）。 ）。 该装置的特征在于，所述双金属（1）穿过所述支撑件（5），以便被固定在双金属片的长度的不同部分被安装时，所述双金属并具有第一（1 c）和 基板（5），位于朝向双金属的自由端（1a）的所述第一部分（1）的对应分别位于一侧和另一的第二部分（1d）的所述对所述表面 有用（1 b）该双金属片的，有用表面是取决于双金属条带的夹紧长度我在支撑可变的长度（5），被视的大小来决定该夹紧长度 装置以获得恒定的热冲程，无论大小如何，以及包括它的电气保护装置。

The present invention relates to an assembly device of a bimetallic strip (1) and a part serving as support (5) to the bimetallic strip in a current breaking device, said bimetallic strip (1) being electrically connected by a first end (1 a) said free end to a first connecting pad (3) of said entry, and by another end through which the bimetal is secured to said support (5) to a second said output connecting pad (4 ). This device is characterized in that said bimetal (1) is mounted through through said support (5) so as to be fixed in different parts of the length of the bimetal, said bimetal and having a first (1 c) and a second portion (1d) located respectively on one side and the other of said substrate (5), the first part located towards the free end (1a) of the bimetal (1) corresponding to said surface useful (1 b) of the bimetal strip, the length of the useful surface being variable depending on the clamping length I of the bimetallic strip in the support (5), this clamping length being determined depending on the size of the apparatus to obtain a constant heat stroke, regardless of the gauge, and a power protection apparatus comprising it.
