Abstract

Coaxial connector provided with a body (20) of electroconductive material which extends in the casing (1) of the connector between the connection ends (18, 19) and is electrically separated therefrom. The body (20) functions as a capacitive coupling medium between the connection ends (18, 19) and thus influences the electrical connection impedance of the connector. Because a body of magnetic material (21) is accommodated at the same time, an inductive coupling can be provided and frequency-dependent impedance matching is possible.

Claims

1. Coaxial connector provided with at least one electrical contact element having a contact side in the form of a coaxial inner and outer contact member for making contact with a further connector, and having a connection side in the form of connection ends, which extend from the inner and outer contact member, for connecting electrical wiring, there is disposed in the connector a body of electroconductive material which extends between the connection ends and is electrically separated therefrom and the body of electrocondcutive material consists of at least one electrical conductor surrounded by electrically non-conductive material and the body of electroconductive material is plate-shaped.

2. Coaxial connector according to claim 1, wherein the inner and/or outer contact member (11, 6) comprises switching contact elements (13, 14) which, in a first position, make electrical contact with each other and, in a second position, are electrically separated, each provided with connection ends (18, 19) extending towards the connection side (4), the body of electroconductive material (20) extends between the connection ends (18, 19) of the switching contact elements (13, 14) and is electrically separated therefrom.

3. Coaxial connector according to claim 1, wherein the body connection means comprise a connection end (26) extending towards the connection side.

4. Coaxial connector according to claim 1, wherein there is disposed in the connector a body of magnetic material which extends between the connection ends and is electrically separated therefrom.

5. Coaxial connector according to claim 4, wherein the body of electroconductive material (20) and the body of magnetic material are combined to form a single entity.

6. Coaxial connector according to claim 5, wherein the combined body consists of an electrical conductor surrounded by magnetic material.

7. Coaxial connector according to claim 1, wherein the connection ends are strip-shaped and have a plane and have elements which are raised with respect to the plane of said connection ends such that, in the assembled state of the connector, said raised elements engage the body of electroconductive material and the body of magnetic material, for the purpose of retaining it between the connection ends in the connector.

8. Coaxial connector according to claim 7, wherein the body of electroconductive material (20) comprises a strip-shaped conductor having elements (24) which are raised with respect to the plane of said conductor, for retention thereof in a duct (25) in the material (21) surrounding the electrical conductor.

9. Coaxial connector according to claim 7, wherein the raised elements are lip-shaped, each having a fixed resilient end and a raised free end, which free end in the assembled state engages the body in question, preferably in guide slots or guide grooves formed for receiving therein the lip-shaped elements.

10. Coaxial connector according to claim 1, provided with a casing (1) of electrically insulating material, further comprising plug and/or socket contact elements (2) accommodated in the casing.

11. Method of assembling a coaxial connector, said connector comprising a casing (1) of electrically insulating material provided with at least one electrical contact element (2) having a contact side (3) in the form of a coaxial inner and outer contact member (11, 6) for making contact with a further connector, a connection side (4) in the form of connection ends (18, 19), which extend from the inner and outer contact member, for connecting electrical wiring and a body (20) which is made of electroconductive and/or magnetic material and extends in the casing between the connection ends, wherein the body of electroconductive material (20) is provided with connection means for connecting further electrical wiring, the body being disposed in a first step between the connection ends of said contact members, and in a further step the assembly, thus formed, of contact members and body being accommodated from the connection side in the casing of the connector.

12. Coaxial connector provided with at least one electrical contact element having a contact side in the form of a coaxial inner and outer contact member for making contact with a further connector, and having a connection side in the form of connection ends, which extend from the inner and outer contact member, for connecting electrical wiring, there is disposed in the connector a body of electroconductive material which extends between the connection ends and is electrically separated therefrom and there is a jacket of magnetic material which extends between the connection ends and is electrically separated therefrom and said jacket is integral with and surrounds the body of electroconductive material.
