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.

DETAILED DESCRIPTION I claim as my invention 1.
An electrical connector especially suitable for coupling an antenna leadin with a printed circuit board and a receiver chassis, comprising: a tubular sheet metal body formed from an originally flat blank and having confronting edges along a longitudinal joint; means at opposite ends of the body for mounting it in functioning position; said body providing a plug-receiving socket opening through one of said ends; a dielectric support located within said body spaced from said one end and carrying an electrical contact insulated from said body; and means connecting the support and the body together including a mechanical interlock retaining the body against spreading open at said joint in the vicinity of said support.
2.
A connector according to claim 1, wherein said mechanical interlock comprises a recess in said support and interlock lug means engaging the support in the recess.
3.
A connector according to claim 2, wherein said recess is of generally frustoconical form at one end of said support, and said interlock lug means comprise a plurality of circumferentially spaced lugs partially struck from the sheet metal body and bent into engagement with the support in the frustoconical recess.
4.
A connector according to claim 2, wherein said recess extends longitudinally in the perimeter of the support, and said interlock lug means comprise a plurality of lugs bent from the body into said recess.
5.
A connector according to claim 1, wherein said joint from said support to said one end is slightly expansible to permit slight expansion yielding of the socket on insertion of an antenna lead-in plug thereinto.
6.
A connector according to claim 5, including an annular series of radially outwardly projecting integrally struck out biting vanes on said body adjacent to said one end and engageable in electrically contacting relation with the surface defining a hole in a chassis opening and also serving to limit expansion of the socket.
7.
A connector according to claim 1, including a pair of laterally extending engagement lugs adjacent to said one end for engagement with one side of a chassis panel and a second pair of engagement lugs spaced from the first mentioned lugs toward said one end, and a fastening clip engageable with said second pair of lugs for grounding and coupling of the connector to a chassis panel
