Embodiment Construction

[0049] according to Figure 1A with 1B , the high-voltage cable 2 is connected to a preferably metallic housing 4 and guided through a cable entry 6 of the housing 4 into the interior. Usually the cable 2 is terminated in the inner space by a contact element 8, for example a contact shoe, such as Figure 1A , Figure 1B shown. The cable 2 is connected to the terminal via the contact element 8 , for example by means of a screw connection. The metal housing is, for example, a metal casting housing, in particular a die-cast aluminum housing.

[0050] especially by figure 2 and combine Figure 1A It can be seen that for the mechanical fastening of the cable 2 to the housing 4 , an eg pot-shaped closure cover 10 is arranged on the cable 2 , which is reversibly fastened to the housing 4 via a snap connection 12 . For this purpose, the cable entry 6 comprises a cable bushing 14 which extends in the cable longitudinal direction in a telescopic manner towards the outside. On its ...

Abstract

In order to ensure a reliable connection of the shielding layer (16) of the high-voltage cable (2) to the housing (4), especially for electric vehicles or hybrid vehicles, the shielding layer (16) of the cable (2) is squeezed Between the inner sleeve (20) and the contact sleeve (18), wherein the electrically conductive connection to the housing (4) is formed via the contact sleeve (18). For this purpose, the contact sleeve (18), which is designed as a crimp sleeve, has a flange consisting of a spring leaf (32). At the same time, the inner sleeve ( 20 ) is also pressed against the cable sheath ( 30 ) of the cable ( 2 ) in order to achieve strain relief. Furthermore, the cable (2) can preferably be fastened to the housing (4) by means of a simple snap-in connection.

Description

technical field [0001] The invention relates to a device for the electrical contacting of the shielding of a cable on a housing, said device comprising a cable, an inner sleeve and a contact sleeve, said cable having a shielding surrounded by a cable sheath and having already In the assembled state, the cable is guided through the cable bushing of the housing into the housing and terminates there in a contact element, the contact sleeve facing all The inner sleeve is pressed and electrically connected to the housing. The invention also relates to a pre-assembled cable for a device according to the invention and for being guided through a cable bushing of a housing, wherein the cable has a cable sheath surrounded by a cable sheath. The shielding layer, the pre-assembled cable has an inner sleeve and a contact sleeve which presses against the inner sleeve below the middle of the shielding layer. Background technique [0002] In this context, the invention relates in particul...
