a composite cable

Abstract

The invention discloses a composite cable, comprising more than one positioning ring, a gap cavity is formed between adjacent positioning rings, an outer protective layer is arranged in each gap cavity, and a cable inner core is arranged inside the outer protective layer The inner core wire of the cable includes an inner protective layer and more than one core wire. The core wire passes through the through hole in the middle of the positioning ring and is fixedly assembled with the positioning ring. The outer protective layer is rotated and installed between the two positioning rings on both sides. There are more than one filling cavities around the outer protective layer in the outer protective layer, and the filling cavities are all filled with water-absorbing substances. The cable of the present invention is mainly used on the water surface, can effectively float on the water surface, and can avoid the damaged position when a part is damaged, and then reseal it to prevent external water from entering the interior, thereby better protecting the cable.

Description

technical field [0001] The invention relates to a cable, in particular to a composite cable. Background technique [0002] A cable is a tool composed of multiple wires to transmit electrical energy or electrical signals. With the continuous progress of society, the use of electrical energy and electrical signals is becoming more and more common. Cables have become an indispensable part of our lives. In waters such as oceans and rivers, due to the rapid development, mechanical equipment is needed, so cables are also required for power supply and communication. In the prior art, ordinary cables are mostly used for power supply and communication, and ordinary cables are difficult to support on the water surface. Therefore people have invented some floating cables at present, are used for using on the water surface. [0003] However, due to the long-term immersion in the water surface of the current water cables, the outer layer of the cable is prone to aging and damage due to ...

Problems solved by technology

In waters such as oceans and rivers, due to the rapid development, mechanical equipment is needed, so cables are also required for power supply and communication. In the prior art, ordinary cables are mostly used for power supply and communication, and ordinary cables are difficult to support on the water surface. Therefore, people have invented some floating cables for use on water

[0003] However, due to the long-term immersion in the water surface of the current water cables, the outer layer of the cable is prone to aging and damage due to pulling, which will eventually lead to cracks in the entire cable. If these cracks are not repaired in time, the internal cables will be damaged immediately. The core wire is damaged, which eventually leads to the interruption of cable communication, etc., which often leads to a reduction in service life
