Description

Overheated destructive socket construction

The present invention relates to a clip that is respectively clamped on the elastic piece and the opposite side edge of the connecting piece by the two clips, so that the elastic piece and the connecting piece maintain elastic contact to form a passage. Moreover, the connecting portion of the limiting member is broken after the working temperature reaches a breaking temperature, so that the elastic piece and the connecting piece are separated by the pop-up to form an open circuit to ensure the safety of the socket structure with the overload protection mechanism.

At present, the power sockets generally used may be caused by line faults, short circuits, excessive load, poor contact, etc., which may cause high temperature due to current overload, and may even cause fire and endanger life and property. Since the conventional conventional socket does not have any overload protection mechanism, it is impossible to automatically cut off the power when the current is overloaded, which is quite dangerous in use.
