ABSTRACT:
An appliance plug includes a front housing part with a collar having a sealing flange and a contact carrier member and a cover plate for contact pins surrounded by the collar and including fastening screws mounted in the contact carrier member. A rear housing part includes a support flange which is engaged from behind by a bayonet ring, and screw columns for the fastening screws in the contact carrier member and a cable insertion member. The end face of the sealing flange is provided with an annular groove and a sealing ring inserted into the annular groove. The rear housing part has a sealing edge which can be pressed into the annular groove or the sealing ring. The collar has an internal flange serving as a support for the contact carrier members and as an abutment for the cover plate. The contact carrier member has locking projections and the cover plate has locking recesses which are engaged by the locking projections. The individual components of the front housing part can be assembled without screws. In addition, the front housing part can be used for other types of plugs.
