Abstract: 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.

Abstract: A socket body has increased retention means for push-on retaining engagement with a tube base supplemental to the usual frictional retaining engagement between mating terminals of the socket and tube base. In one form the increased retention means comprises a compressible split key. In another form the increased retention means comprises gripping fingers.

Abstract: A method of making an electrical connector especially suitable for coupling an antenna leadin with a printed circuit board in a receiver chassis comprising forming up a tubular sheet metal body from an originally flat blank into tubular form with confronting edges along a longitudinal joint, providing opposite ends of the body with means for mounting it in functioning position, assembling within the body a member such as a dielectric support carrying an electrical contact in electrically contacting relation at a location within the body spaced from one end of the body which provides an opening into a plug-receiving socket between said one end and said support and mechanically interlocking the dielectric support and the body to retain the body against spreading open at the joint in the vicinity of the support. More specifically, interlocking lug-means are driven from the body into a recess in the support to effect the interlocking relationship.

Abstract: A simple three-piece binding post is provided having a hollow generally tubular housing for mounting on a support such as a binding post panel, a binding plunger reciprocable within the housing, and a spring for engagement with the support and for thrusting the plunger to bind a lead terminal inserted into normally offset but alignable lead-receiving openings in the housing and plunger.

Abstract: Clamping means such as stiffly resilient gripping fingers are mounted on and about the perimeter area of the grounding shell of a phonojack assembly for thrusting plug shell finger tabs into positive electrical contact with the grounding shell. In a desirable form, the clamping means comprise stiffly resilient gripping fingers on a sleeve secured to the end portion of the grounding shell which is adapted to be secured in grounding relation to a television receiver chassis component. High frequency leakage shielding means are also provided.

Abstract: 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.

Abstract: An electrical connector especially suitable for coupling an antenna leadin with a printed circuit board in a receiver chassis comprises a tubular sheet metal body formed from an originally flat blank and with confronting edges along a longitudinal joint. Opposite ends of the body have means for connecting it in functioning position. One end of the body provides a plug-receiving socket. A dielectric support located within the body spaced from the socket end carries an electrical contact for engagement by a plug inserted into the socket. Means connecting the dielectric support and the body together include a mechanical interlock retaining the body against spreading open at the joint in the vacinity of the support. A plurality of forms of the interlock are provided. A method of making the connector is disclosed.
