Abstract

The invention discloses a compressive cable, which comprises an inner core layer, an anti-electromagnetic interference layer, wire core conductors and an elastic layer, wherein the anti-electromagnetic interference layer is arranged outside the inner core layer; the wire core conductors are arranged in the inner core layer; the elastic layer is arranged outside the anti-electromagnetic interference layer; more than three end parts are arranged on the inner surface of the elastic layer in a ring; elastic holes are formed in the end parts; gaps are formed between the elastic layer and the anti-electromagnetic interference layer; elastic balls are arranged in the gaps; a wear-resistant layer is arranged outside the elastic layer; support strips are matched between the wear-resistant layer and the elastic layer; and a collapse gap is formed in the axis position of the inner core layer. The cable provides an elastic space through the gaps between the elastic layer and the anti-electromagnetic interference layer; and the wire core conductors are prevented from being directly compressed by external pressure. Meanwhile, the gaps are also filled with the elastic balls, so that the elasticity is increased; springback of stress after disappearing is facilitated; the success rate of laying the cable can be effectively improved by the device; and meanwhile, the fault rate is reduced.

Description

technical field [0001] The invention relates to a pressure-resistant cable. Background technique [0002] The cable is a common electrical equipment. The laying conditions of the cable are relatively harsh, but it is inevitable that the cable will be deformed by extrusion. Transmission and post-maintenance are very troublesome; affecting the daily life of residents. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a compression-resistant cable, which provides an elastic space through the gap between the elastic layer and the anti-electromagnetic interference layer, avoiding external pressure from directly compressing the core conductor, and at the same time filling the gap. There are elastic balls to increase the elasticity, which is convenient for the spring after the pressure force disappears. This device can effectively improve the success rate of cable laying and reduce the failure rate at the same time. [...
