An electrical connector of the type known in the television industry as A.C. interlock plug, comprises a dielectric body having opposite faces and an opening extending therethrough and through both of the opposite faces. A contact member having a pin body and a solder lug extending from one end of the body, has the solder lug projecting through the opening, a shoulder on the pin body engaging the dielectric body as a stop and spur means on the solder lug retainingly engaging with the dielectric body to prevent withdrawal of the contact member. The contact member may be formed up from sheet metal into a tubular pin body and a transversely arcuately reinforced solder lug on which the spur means comprise one or more shear formed pointed projections along the edges of the solder lug. The contact member may be formed up from sheet metal into a tubular pin body and a transversely arcuately reinforced solder lug on which the spur means comprise one or more shear formed pointed projections along the edges of the solder lug. In assembling the contact member with the dielectric body, the solder lug is inserted into the preformed opening in the dielectric body through the principal face of the dielectric body until the pin body shoulder stops against the dielectric body, and the spur means slide easily into the preformed opening but positively bitingly engage the dielectric body against withdrawal of the contact member.

A.C. Interlock plug, contact and method

A snap-in electrical connector assembly, more particularly a power transistor socket, has a body provided with a plurality of retaining fingers each of which has a plurality of retaining shoulder lugs located in differential spaced relation to the plane of a base surface of the body so that the assembly can be mounted on selectively a plurality of different thicknesses of supporting panel by simple snap-in mounting procedure. A positive mounted retention of the assembly is maintained, but release and removal are facilitated. As many as four different mounting panel thicknesses are accommodated according to preferred examples.
