Title: Antenna connector
Claims: 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. 8. A connector according to claim 1, including a pair of parallel diametrically opposite transverse slots adjacent to the opposite of said ends for engagement therein of rails to facilitate handling of the body for assembly of the support therein for completing the mechanical interlock. 9. A connector according to claim 1, including attachment lugs on the opposite end of the body for engagement with the printed circuit board, shoulders adjacent to the lugs for engaging the circuit board, and notches provided in the body adjacent to said shoulders to facilitate drainage from within the body. 10. A connector according to claim 1, in combination with the printed circuit board and a mounting panel of the receiver chassis, the end of said body opposite to said one end fixedly secured to the circuit board, said panel having an opening therethrough for said body, said one end inserted through said opening, and said mounting means at said one end effecting electrically grounded connection with said panel. 11. A combination according to claim 10, wherein said mounting means comprise a pair of lugs engaging one side of the panel, a pair of lugs spaced from said panel engaging lugs slightly greater than the thickness of the panel, the panel having extensions of said opening to clear said spaced lugs therethrough, and retaining clip means engaging the panel across said extensions and engaging said spaced lugs to retain the body in position relative to the panel. 12. A combination according to claim 10, wherein said opening is circular, and said mounting means comprise an annular series of vanes having biting edges engaging the panel within the opening. 13. An electrical connector in combination with a printed circuit board and a receiver chassis and suitable for coupling an antenna leadin with the printed circuit board, comprising: the connector having a tubular sheet metal body provided at one end with means connecting it to the printed circuit board; the opposite end of the body providing a plug-receiving socket; said panel having an opening to receive said opposite end of the body therethrough; means on said opposite end of the body for mounting the body on the panel by assembling said opposite end through said opening; said mounting means comprising first lug structure partially struck from said body and projecting laterally therefrom and engaging the backside of the panel adjacent to said opening; second lug means on said body spaced from said first lug means and from the plane of a front side of the panel; and retaining clip means between said second lug means and said panel front side for maintaining the connector in mounted relation to the panel. 14. 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; said body having means at one end for connection with a printed circuit board; the opposite end of said body providing a plug-receiving socket and having means for mounting the body on a chassis panel by assembling said opposite end through an opening in the panel after said one end has been permanently connected to the board; a member located within said body; and means connecting said member and said body together including a mechanical interlock retaining the body against spreading open at said joint. 15. A connector according to claim 14, in combination with the printed circuit board and a mounting panel of the receiver chassis, said one end of the body fixedly secured to the circuit board by said connection means at said one end, said mounting panel having an opening therethrough and said opposite end of the body received in said opening, and said mounting means effecting electrically grounded connection with said panel. 16. A combination according to claim 15, wherein said mounting means comprise a pair of lugs engaging one side of the panel, a pair of lugs spaced from said panel engaging lugs slightly greater than the thickness of the panel, the panel having extensions of said opening to clear said spaced lugs therethrough, and retaining clip means engaging the panel across said extensions and engaging said spaced lugs to retain the body in position relative to the panel. 17. A combination according to claim 15, wherein said opening is circular, and said mounting means comprise an annular series of vanes having biting edges engaging the panel within the opening. 18. A connector according to claim 14, wherein said mounting means comprise an annular series of circumferentially spaced vanes having biting edges for engagement with a surface defining the opening in the panel. 19. A connector according to claim 18, said vanes extending in generally helical relation to the axis of the body to resist axial displacement of the body relative to the panel.
