[0002] Cables are made of one or more mutually insulated conductors and an outer insulating protective layer, and are used to transmit electricity or information from one place to another. With the widespread application of modern automation equipment, the application of drag chain cables has become more extensive. Drag chain cables are widely used in various fields, such as robot body cables, servo cables, linear motors, industrial Ethernet, etc. Because drag chain cables need to be moved frequently during use, the requirements for the flexibility, tensile strength, wear resistance and other properties of drag chain cables are relatively high. The quality of these properties directly affects the service life of drag chain cables.

[0003] The existing drag chain cables are frequently moved, so the cables will rub against the outside world during the movement, and long-term friction can easily cause cable damage. Utility Model Content

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a double-shielded drag chain cable, comprising a group of wire cores, the outer walls of a group of the wire cores are all provided with an insulating layer, the outer walls of a group of the insulating layer are provided with a first shielding layer, the outer walls of a group of the first shielding layer are provided with a filling layer, the inner walls of the filling layer are provided with a group of tensile cotton ropes, the outer walls of the filling layer are provided with a second shielding layer, the outer walls of the second shielding layer are provided with a flame retardant layer, the outer walls of the flame retardant layer are provided with a high temperature resistant layer, the outer walls of the high temperature resistant layer are provided with an outer sheath, the outer wall of the outer sheath is fixedly installed with a group of wear-resistant blocks, and the inner walls of a group of the wear-resistant blocks are rollingly provided with wear-resistant balls.

[0006] Preferably, a flexible filler is provided between the filling layer and the tensile cotton rope, and the thickness of the insulating layer is 0.6 mm to 0.8 mm.

[0010] Compared with the prior art, the advantages and positive effects of the utility model are:

[0011] 1. In the utility model, a wear-resistant block is arranged on the outer layer of the cable. When the cable moves, the cable will first rub against the wear-resistant block when it rubs against the outside world. At the same time, a rolling wear-resistant ball is arranged on the wear-resistant block, which will change the sliding friction of the cable during the movement into rolling friction, thereby reducing the resistance of the cable when it moves, and also reducing the probability of the cable being damaged by friction when it moves. A filling layer is arranged inside the cable, and the flexible filling material in the filling layer can play a role of buffering and protection, which can prevent the cable from being damaged by mechanical extrusion or impact by external objects. The tensile cotton rope plays a role in enhancing strength and stability in the cable. It can increase the tensile resistance of the cable and prevent the cable from being broken or deformed by large tension.

[0012] 2. In the utility model, a first shielding layer and a second shielding layer are arranged inside the cable to improve the anti-interference ability of the cable. A flame retardant layer is arranged to prevent the cable from burning under flame or high temperature, thereby reducing the risk of fire.
