Embodiment Construction

[0045] Figure 1a The cable 11 before actuation of the ground joint 12 and the ground joint 12 of the invention encasing the cable 11 are shown in a schematic cross-sectional view perpendicular to the extension of the cable 11 .

[0046] The ground joint 12 includes a joint body 13 . The joint body 13 is circular (or annular). The joint body 13 is surrounded by a housing 14 . The connector body 13 has an opening 15c on one side, which is delimited by two tabs (ears) 15a, 15b. The joint body 13 also includes several blade-shaped opening elements 16 . Each blade has a cutting edge at its end.

[0047] The cable 11 includes an outer sheath 17, usually made of plastic, and an inner conductor 18, usually made of metal. Although the outer sheath 17 sits directly on the inner conductor 18 , it is not bonded to the inner conductor 18 . exist Figure 1a In , the internal structure of the cable 11 inside the inner conductor 18 is not shown for simplicity (compared to FIG. 6 which s...

Abstract

The invention relates to a ground connector (12, 21, 31, 41, 51) for earthing a cable (11), in particular a coaxial cable, wherein the cable (11) has an outer jacket (17) closely surrounding an inner conductor (18), the ground connector (12, 21, 31, 41, 51) comprising a connector body (13, 22, 32, 52), in particular a sleeve-type connector body (13, 22, 32, 52), with at least one contact element (43, 55) for providing electrical contact between the connector body (13, 22, 32, 52) and the inner conductor (18) of the cable (11), characterized in that the ground connector (12, 21, 31, 41, 51) comprises at least one opening element (16, 24, 33, 42, 54) so designed to cut and / or perforate the outer jacket (17). The invention further relates to a method for earthing a cable with such a ground connector. The inventive ground connector is easier to install than known ground connectors.

Description

technical field [0001] The invention relates to a grounding joint for grounding a cable, especially a coaxial cable, wherein the cable has an outer sheath tightly surrounding an inner conductor, the grounding joint comprises a joint body, in particular a bushing type joint body, the joint The body carries at least one contact element for providing electrical contact between the connector body and the inner conductor of the cable. Background technique [0002] A ground joint of this type is disclosed in WO 02 / 03501 A1. [0003] Radio frequency (=RF) cables can be used for various purposes, eg for mobile radiotelephony, radio broadcasting or directional radio broadcasting. In particular, the antenna is connected to a receiver (such as a television) and a transmitter by an RF cable. [0004] To protect users and buildings, these cables must be grounded. [0005] The cable has a protective, electrically insulating outer sheath, usually made of plastic or rubber. Although suc...
