Abstract
An electrical plug-like connector, in particular a socket or cigar(ette) lighter in motor vehicles having a sleeve-like guide part for axially accepting a cigar(ette) lighter or a connector plug of an electrical device. A first fixed contact is arranged in the sleeve base region on an insulation carrier. The fixed first contact is acted upon by a counter contact, and the electrically conductive guide part forms a second fixed contact that acts upon other counter contacts. Thermal overload protection is also provided. Parallel to the thermal overload protection and at a distance from the insulation carrier, a sheet metal insert is provided, extending in the sleeve base section. On the underside of the sheet metal insert, an electrically-conductive bimetal-switch spring is fixed such that such that in the non-operative condition the bimetal switch spring acts upon the first fixed contact or upon a side contact connected with the side contact. The diameter of the sheet metal insert is less that the internal diameter of the sleeve-like guide part, such that the sheet metal insert can be introduced axially into the guide part from its opening side. In the final-assembly condition, the s…
