A connecting element (V) for a coaxial high-frequency cable (K) that has an inner conductor (1), a dielectric (2) that surrounds the inner conductor, and a tubular outer conductor (3) that is concentric to the inner conductor (1). The end of the cable (K) is widened in the shape of a cone to create an encircling contact area. The connecting element (V) comprises a jack (6) with an encircling projection (8) that is designed to make contact with the inner surface of the contact surface (5) of the outer conductor (3), whereby the projection (8) has a conical outer surface, said jack further including a tubular segment (7) that surrounds the outer conductor (3) in the use position. The connecting element also has an axially movable contact sleeve (12), which on one end has an encircling, inner surface that is widened conically and is designed to come into contact with the outer surface of the contact surface (5) of the outer conductor (3). The contact sleeve (12) can be pressed against the contact surface (5) of the outer conductor (3) by a rotating movement of the jack (6). To improve the intermodulation characteristics of the connecting element (V), the outer surface of the contact sleeve (12) is also conical. A compression jack (13) can be pushed over the contact sleeve (12) in the axial direction, with an inner surface that is widened conically and is designed to make contact with the outer surface of the contact sleeve (12), which inner surface can be pressed by the rotating movement of the jack (6) against the contact surface (5) of the outer conductor (3).

Connecting element for a coaxial high-frequency cable

A spacer is indicated for a high-frequency coaxial cable with an inner conductor, a tube-shaped outer conductor and a dielectric cavity located between the two conductors which, through the use of different materials, has a higher thermal load capacity in the inner conductor area than in the outer conductor area. When installed, the parts, which are composed of different materials and are superimposed in the radial direction, are mechanically interconnected.

Two part spacer for a high-frequency coaxial cable

A spacer is indicated for a high-frequency coaxial cable with an inner conductor, a tube-shaped outer conductor and a dielectric cavity located between the two conductors, which has a higher thermal load-carrying capacity in the inner conductor area than in the outer conductor area, due to the use of different materials. The parts of the spacer which are made of different materials are radially superimposed and are solidly interlocked with each other by means of injection molding.
