Abstract

A coaxial connector is suitable for being received in an opening in a panel, in particular a wall of a metal box. The connector comprises a conductive tubular body, a conductive tubular grounding plate and at least one resilient member, said grounding plate being movable in translation coaxially relative to said body, said grounding plate having a continuous rigid bearing surface for pressing against said panel, and said at least one resilient member, in particular a spring, being arranged to urge the grounding plate into a given position relative to the tubular body and to press the grounding plate against said panel when the connector is assembled with a complementary connector element.

Claims

1. A coaxial connector suitable for being received in an opening of a panel, in particular a wall of a metal box, the connector comprising a conductive tubular body, a conductive tubular grounding plate and at least one resilient member, said grounding plate being movable in translation coaxially relative to said body, said grounding plate having a continuous rigid bearing surface for pressing against said panel, and said at least one resilient member, in particular a spring, being arranged to urge the grounding plate into a given position relative to the tubular body and to press the grounding plate against said panel when the connector is assembled with a complementary connector element.

2. A connector according to

claim 1

, wherein the body and the grounding plate are circularly symmetrical.

3. A connector according to

claim 1

, wherein the body has an extension from its side wall constituting a housing in which said grounding plate can move axially.

4. A connector according to

claim 3

, wherein the extension has a second wall parallel and outside the wall of the body, said wall being interconnected by a radial wall defining the end wall of the housing.

5. A connector according to

claim 3

, wherein the grounding plate has a tubular portion that engages in the housing of the body, and that is extended at each end by a respective rigid radial collar, one of said collars being outwardly directed and forming the bearing surface for pressing against said panel, the other collar being inwardly directed and suitable for being brought to bear against the end wall of the housing of the body.

6. A connector according to

claim 3

, wherein the tubular portion of the grounding plate co-operates with the wall of the body to form a second housing in which the resilient member is received, the inwardly-directed radial collar defining an end wall for said second housing and serving as a first bearing surface for the resilient member.

7. A connector according to

claim 6

, including a fitting secured to the body and arranged to define a second bearing surface for the resilient member.

8. A connector according to

claim 7

, wherein the fitting is substantially tubular in shape and is arranged in such a manner as to engage in part in the second housing of the grounding plate.

9. A connector according to

claim 1

, including snap-fastening means suitable for co-operating with corresponding means on a complementary connector element.

10. A connector according to

claim 9

, wherein the complementary connector element is a coaxial socket mounted on a printed circuit card placed in a metal box having an opening through which said connector is engaged.

11. A connector according to

claim 9

, wherein the resilient member is a spring arranged in such a manner that its return force is smaller than the force required for disengaging the connector from the complementary connector element.

12. A connector according to

claim 1

, wherein the opening in the panel is made in such a manner that when the connector is received in said opening, the connector can move radially in said opening, while the grounding plate remains in contact with the panel.
