Abstract

In a cable clamp for fixing an electrical cable (8) that is connected to a connector, it is proposed to insert a clamping element (10) into a cylindrical cable receptacle (2) integrally moulded on the connector housing (1) such that it can be displaced by means of a pressure screw (20). Clamping fingers (13) that are integrally moulded on the clamping element (10) fix the electrical cable (8) extending within the clamping element (10) while guiding fingers (12) integrally moulded on the clamping element (10) prevent the clamping element (10) from turning.

Claims

1. A device for fixing an electrical cable that is connected to a connector, comprising

a connector housing with a cylindrical cable receptacle integrally moulded thereon, wherein

a clamping element can be inserted into and displaced in the cable receptacle using a pressure screw, wherein

the clamping element features several fingers that are combined into a ring structure on one end, wherein

the fingers have two difference shapes, wherein

a first shape is realized in the form of a guiding finger and a second shape is realized in the form of a clamping finger, wherein

the guiding fingers and the clamping fingers are arranged alternatively and thusly form the ring structure of the clamping element, wherein

the clamping fingers feature a wedge-shaped end and the guiding fingers feature a smooth end, wherein

that wedges are integrally moulded into the cable receptacle at an axial distance from the insertion and end such that they progressively extend inward and are spaced apart from one another, wherein

a thread is formed within the cable receptacle and features a longitudinal recess in the regions, on which the wedges are integrally moulded, and wherein

the wedge-shaped ends of the clamping fingers of the clamping element come in contact with the wedges of the cable receptacle and progressively reduce the inside diameter when the clamping element is screwed into the cable receptacle using the pressure screw such that a cable extending within the clamping element is fixed.

2. The device according to claim 1, wherein

the clamping fingers are guided in the longitudinal recesses in the thread of the cable receptacle during the assembly.

3. The device according to claim 1, wherein

the guiding fingers are guided between the wedges in the region of the thread in the cable receptacle when the clamping element is screwed down using the pressure screw such that the clamping element is prevented from turning.

4. The device according to claim 1, wherein

that the clamping element is held on the pressure screw with the aid of a locating device.
