German standard mains plug having an insertion aid associated with the connection bush for the protective earth conductor

摘要

In the case of an injection-moulded German standard mains plug for electrical devices which can be connected to a mains plug socket, having an essentially U-shaped plug bridge for holding an earthing spring with a hollow cylindrical connection bush for the protective earth conductor of a load cable, with an insertion funnel having a conical throughbore being assigned to this connection bush, this insertion funnel is formed on an L-shaped moulding (21) which projects from the planar base plate of the plug bridge (1) and projects over the connection bush (19). This produces a plug bridge which is optimised with regard to production technology insofar as the cooling times are reduced by the lower material requirements for the moulding. <IMAGE>
