DEVICE FOR THE ELECTROMAGNETICALLY COMPATIBLE CONNECTION OF ELECTRICAL CONDUCTORS WITH A SCREENING LAYER

Abstract

The subject of the present invention is a device for the electromagnetically compatible connection of electrical conductors (3.sub.1, 3.sub.2, 3.sub.n) with screening layers (2.sub.1, 2.sub.2, 2.sub.n) against interference fields, particularly in motor vehicles. The conductors (3.sub.1, 3.sub.2, 3.sub.n) to be connected are held in a housing (5) of the device, also known as a high-voltage distributor. In order to guarantee the electromagnetic screening, the screening layers (2.sub.1, 2.sub.2, 2.sub.n) of the stripped cables are folded backwards and pulled over contact sections (1.sub.1, 1.sub.2, 1.sub.n) of the housing (5) provided for the purpose, as a result of which electrical contacting occurs. The screening layers (2.sub.1, 2.sub.2, 2.sub.n) are affixed by one clamp (4.sub.1, 4.sub.2, 4.sub.n) respectively.
