Description
Technical Field

Background
The conductive elastic sheet is an elastic sheet structure which is generally arranged in a power switch or breaker structure and is used for electrifying or interrupting a circuit loop.
Fig. 1 and 2 are a schematic diagram of a conventional conductive elastic sheet. As shown in fig. 1 and fig. 2, the conventional conductive elastic sheet includes a conductive elastic sheet 201, a first terminal 202 and a second terminal 204; the conductive elastic sheet 201 comprises a first contact 203, the first contact 203 is arranged at one end of the conductive elastic sheet 201, and the other end of the conductive elastic sheet 201 is connected with the first terminal 202; the second terminal 204 includes a second contact 205, and the first contact 203 corresponds to the second contact 205. The first contact 203 of the conductive elastic sheet 201 is contacted with or separated from the second contact 205 of the second terminal 204, so that the circuit loop is in a power-on or power-off state.
In order to avoid the danger of overheating the circuit or fire of the wire due to current overload, the conventional conductive elastic sheet 201 is made of metal sheet and is slightly bent, so that the conductive elastic sheet 201 can be deformed and bent reversely to bounce after being heated, and further the first terminal 202 is separated from the second terminal 204, thereby avoiding the situation that the electronic and electrical equipment is burnt due to overheating, and ensuring the safety of power utilization.

Moreover, if the conductive elastic sheet 201 is not completely tripped, the electronic and electrical equipment in the whole current loop is easily unstable in current due to repeated power-on and power-off, so that the electronic and electrical equipment is crashed or cannot normally operate, and the service life of the equipment is greatly shortened; moreover, in the process of repeated power-on and power-off, phenomena such as sparks, heating and fire are easy to occur, and serious casualty accidents such as fire disasters can be caused.

In the embodiment of the present invention, the supporting member 50 is made of a high temperature resistant material.
Fig. 4 is a simplified schematic diagram of a structure of a supporting member of a conductive elastic piece according to a preferred embodiment of the present invention.
