Abstract

The invention relates to an assembly and method for sharing a thermal destruction fixing piece by a plurality of conductive slots. The assembly comprises a first conductive piece, a second conductive piece and a thermal destruction fixing piece, wherein the first conductive piece comprises a front end, a rear end, a plurality of conductive slots, a connection part and a contact part, each conductive slot comprises a front-end conducive slot and a rear-end conductive slot, a control zone is defined between the front-end conductive slot and the rear-end conductive slot, the connection part is arranged on the control zone, the contact part is connected with the connection part, the second conductive piece is contacted with the contact part by the thermal destruction fixing piece, the thermal destruction fixing piece is further shared by the plurality of conductive slots, and the thermal destruction fixing piece can reach a default temperature and is damaged when an arbitrary conductive slot reaches a respective limit working temperature.

Description

technical field [0001] The present invention relates to a component and method for sharing a heat-damage fixing part with multiple conductive slots, especially to make multiple conductive slots share a heat-breakable fixing part. When any conductive slot reaches its respective limit operating temperature, it can be used Components and methods for the failure of the thermally destructive fixture upon reaching the default temperature. Background technique [0002] To avoid current overload, short circuit, overheating and other conditions in the circuit, a fuse or a breaker is usually installed on the circuit. When the temperature of the circuit is too high or the current is too large, the fuse will be blown by the high temperature or the metal of the breaker will be blown. The shrapnel jumps off to make the circuit open and cut off the power to ensure the safety of electricity use. [0003] For example, there is Taiwan Invention Patent Publication No. I371053 "Thermal Fuse Co...

Problems solved by technology

[0004] But No. I371053 patent case, this has following shortcoming at least, comprises: 1. except a few metal elements such as bismuth, tin, indium and alkali metal, most of metal melting points are all above 300 ℃, for example the melting point of copper is 1084.6°C, and the melting point of iron is 1535°C; in the above-mentioned patent No. I371053, if a metal with a melting point below 300°C is selected as the hot-melt metal, there will be a problem of insufficient bonding strength, and the two terminals will not be able to be firmly bonded. Even if the bonding strength is acceptable, there will be problems with the high price

2. The hot-melt metal is a conductive material. When the hot-melt metal is fused, if the hot-melt metal part remains on the two terminals, the residual hot-melt metal is likely to cause false contact between the two terminals, so it cannot be fully connected. power outage

[0008] However, in the M433670 previous case, the distances between the slots and the overload protection switch are different, so in actual use, each slot has a certain temperature difference from the overload protection switch under the influence of the heat conduction distance. The greater the temperature difference between the remote slot and the overload protection switch, the more difficult it is for the overload protection switch to act in real time to cause a power outage when the temperature of the remote slot is too high, and there is still a problem of insufficient safety in use.
