Abstract
A device for relieving the strain on cables, in particular mains supply cables to housings of electrical equipment, consists of two parts fitted into one another approximately concentrically, of which the outer part (1) can be fastened in a housing opening and the inner part (2) is rotatably mounted in the outer part (1), a central lead-through opening (14) for the cable, and also clamping fingers (12) which protrude into the lead-through opening (14), can be swivelled into the lead-through opening (14) by rotation of the inner part (2) relative to the outer part (1) and can be locked in a clamping position. In order to achieve a more reliable clamping grip and a simpler assembly, the swivelling direction of the clamping fingers (12) runs approximately transversely to the longitudinal axis of the cable lead-through opening (14), the clamping fingers (12) being arranged on the outer part (1) and lying approximately in the direction of the cable lead-through opening (14). Run-up lobes (19) for actuating the clamping fingers ( 12) sitting on the outer part (1) are provided on the inner surface of the inner part (2). Four clamping fingers (12) arranged in a uniformly distributed manner…
