Abstract
Description
Technical Field
[0001] This application relates to the field of cable protection technology, specifically a protective sleeve for glass-limited braided pultruded cables. Background Technology
[0002] A cable is a conductor consisting of one or more mutually insulated conductors and an outer insulating protective layer, laid underground, in the air, etc. Cables generally consist of three parts: a conductor, an insulation layer, and a protective layer. There are usually two types: power cables and control cables. Power cables are mainly used for the transmission and distribution of electrical energy; control cables are mainly used for measurement, protection, and control circuits. Cables are characterized by internal conductivity and external insulation, while glass-insulated braided pultruded cables are a special type of cable.
[0003] To protect cables, a protective sleeve is usually installed on the outer surface of the cable. However, the existing cable protective sleeves are hollow tubes, and the cables are installed and removed by inserting and pulling. Friction between the cable and the sleeve can easily cause wear on the cable insulation layer. In addition, the installation and removal operation is inconvenient and has poor applicability.

At this time, the upper fixing plate 2 is rotated again to move the second half-tube 4 to a position directly above the first half-tube 3. Then, the lead screw 7 is rotated, and the lead screw 7 will move downward under the action of the thread on the fixing block 6. The movement of the lead screw 7 will drive the second half-tube 4 to move downward through the connecting plate 5, so that the first half-tube 3 and the second half-tube 4 fit together, so that the cable is sleeved in the first half-tube 3 and the second half-tube 4. Then, the first half-tube 3 and the second half-tube 4 are buried. When it is necessary to repair the cable, the lead screw 7 is rotated to separate the second half-tube 4 from the first half-tube 3. The above structure makes it easy to put the cable into the sleeve, which can effectively prevent the cable insulation layer from being worn. The operation is simple and convenient, thereby improving the applicability of the sleeve.

[0034] In use, place the lower fixing plate 1 in the designated position, then rotate the upper fixing plate 2 to insert the cable into the first half-tube 3. At this time, rotate the upper fixing plate 2 again to move the second half-tube 4 to the position directly above the first half-tube 3. Then rotate the lead screw 7, and the lead screw 7 will move downward under the action of the thread on the fixing block 6.
