Abstract
An electric switchgear having at least one switching element that is a semiconductor with a temperature-dependent resistance, which includes a housing joined together from a metal cap and a closing element made of plastic. Contact tabs of the switching element are inserted into recesses of the closing element, and the metal cap and the closing element are connected with one another by a joining element made of plastic which is cast on on the outside and which surrounds the edge of the metal cap and surrounds the closing element at least partially.
Claims20
An electric switchgear comprising:
- at least one switching element which is a semiconductor with a temperature-dependent resistance and which has contact tabs;
- and
- a liquid-tight housing, the switching element being arranged in the housing such that the contact tabs project out of the housing, the housing including:
- a metal cap and a plastic closing element that are joined together, the metal cap having inner and outer surfaces, the closing element having recesses, the contact tabs being inserted into the recesses of the closing element;
- and a plastic joining element cast on the outside of the metal cap and the closing element, the plastic joining element connecting the metal cap and the closing element with one another and completely surrounding the edge of the metal cap such that the plastic joining element extends over the inner and outer surfaces of the metal cap and at least partially surrounding the closing element.
A switchgear according to claim 12, wherein the edge of the metal cap is bent.
