Description

A wear-resistant reinforcement sleeve for line connection and use method thereof

Technical Field

The present invention relates to the technical field of cable butt joint, and more particularly to a wear-resistant reinforcing sleeve for line butt joint and a use method thereof.

Background technique

Cable splicing refers to connecting two sections of cable together to form a continuous electrical connection. Sometimes, the length of the cable may not be enough to cover the required distance. By splicing the cables, its length can be extended so that it can be connected to a farther location. In addition, the cable may be damaged or need to be replaced. Splicing can be used to connect new cable segments to restore the entire system to normal operation. Therefore, it is widely used in practice. However, the cable splicing may be affected by the external environment, mechanical action or human factors, resulting in some problems at the splicing. For example, there may be poor contact, insulation damage, moisture intrusion, corrosion, mechanical damage, etc., which will affect the normal use of the cable splicing. Therefore, it is very important to properly protect and maintain the cable splicing.

Patent No. CN114709790A, a sealing protection device suitable for the joint of low-voltage cables, including a shell with a shell inlet pipe, the shell is connected to a cover body, and the shell is processed with a frame placement groove for accommodating a lifting sealing frame on the top open end face; a ring body step groove is arranged at the edge position of the frame placement groove, and the shell is provided with an adjustment hole connected to the frame placement groove, and a lifting telescopic plate is inserted in the adjustment hole, and the lifting telescopic plate is located inside the telescopic plate frame and is driven by the telescopic plate connecting piece; the telescopic plate connecting piece is inserted into the bottom end of the threaded sleeve, and the top end of the threaded sleeve is connected to the connecting hole of the cover body by a fastening screw; the bottom surface of the cover body is provided with a cover body sealing ring corresponding to the position of the ring body step groove.

In view of the above technical scheme, it can achieve effective protection at the connection position of the underground pre-buried cable, and the sealing performance can be effectively improved through the effective connection of various internal sealing components. However, since the cables will be pulled and dragged during laying, and the above scheme only completes the sealing effect on the outside, it is easy to cause the cable to move, the joints to loosen, or even fall off, affecting the connection and protection of the cables. In the process of dragging, the position of the cable joint is prone to friction with the outside world, which may cause the joint to leak, affecting the cable joint effect, or causing safety problems such as leakage.
