Abstract

The invention relates to a device for connecting a coaxial cable to a printed circuit card. The device comprises:

a body having a connection face and a housing suitable for receiving the end of a coaxial cable having conductors comprises a central core and an outer braid;

a fixing means suitable for holding said body with its connection face against a printed circuit card; and

two axially compressible contact studs secured to the body and disposed in such a manner that one of them is electrically connected to the central core of the coaxial cable while the other one of them is electrically connected to the outer braid of the coaxial cable when the end of the coaxial cable is placed in said housing, each stud having an outer end outside the body projecting from the connection face thereof.

Claims

1. A device for connecting a coaxial cable to a printed circuit card, the device comprising:

a body having a connection face and a housing suitable for receiving the end of a coaxial cable having conductors comprising a central core and an outer braid;

a fixing means suitable for holding said body with its connection face against a printed circuit card; and

a two axially compressible contact studs secured to the body and disposed in such a manner that one of them is electrically connected to the central core of the coaxial cable while the other one of them is electrically connected to the outer braid of the coaxial cable when the end of the coaxial cable is placed in said housing, each stud having an outer end outside the body projecting from its connection face.

2. A device according to claim 1, wherein each contact stud includes, opposite from its outer end projecting from the connection face, an inner end inside the body projecting into the housing, each inner end being organized so that the respective corresponding conductor of the coaxial cable comes into contact with the stud when the coaxial cable is put into place with its stripped end inside the housing of the body.

3. A device according to claim 1, wherein the body is made of two complementary portions each having a half-housing for the end of the coaxial cable, the two portions being suitable for closing on said end of the coaxial cable to hold onto said end.

4. A device according to claim 1, wherein the contact studs are made by compacting metal wires of very small diameter, e.g. molybdenum wires having a diameter of 0.01 mm.

5. A device according to claim 1, wherein the fixing means is constituted by a base suitable for receiving the body and for snap-fastening to hold the connection face against the printed circuit card.
