Abstract

Connection for joining end to end, two sections of coaxial cable, comprising two metallic half-shells having elastic and truncated cone-shaped ends, by centering and fixing the halfshells round the central conductor of the sections and of the ends of their external conductors and clamping the ends of the half-shells onto the ends of the external conductors.

Claims

1. In a device connecting together the external conductors of two sections of disk-insulated coaxial cables whose inner conductors are also connected, said device including two metallic half-shells arranged between the ends of said external conductors, a sleeve covering said half-shells and being internally threaded at its ends, and a nut fitted onto each of said conductors and screwed onto the ends of said sleeve clamping the device to the external conductors, the improvement comprising:

an insulating end member fitted into each of the external conductors, and receiving the central conductor and having a flange abutting the end of the external conductor and wherein the two half-shells each have an internal groove which receives the flange of a respective end member, a ring having a tapered internal surface facing the ends of said half-shell, the ends of said half-shells being chamfered on their outer surfaces and provided with longitudinal slots, wherein the two nuts are screwed into the internal threads of the sleeve and clamping, by means of the rings, the ends of the half-shells onto the conductor.

2. The device according to claim 1, wherein:

the insulating end members each have a peripheral groove into which the external conductors are deformed.

3. The device according to claim 1, wherein:

an insulating and centering disk for the internal conductor is arranged within the half-shells, and received within fixing grooves of said half-shells.

4. The device according to claim 1, wherein:

the internal ends of the half-shells are threaded for better adherence to the external conductors of the two sections.

5. The device according to claim 1, wherein the end members and the insulating disk are made of an insulating material having great mechanical strength and good electrical properties.

6. The device according to claim 5, wherein the insulating mAterial is polyphenylene oxide.
