Line repair device

Abstract

The invention relates to the field of cable maintenance, in particular to a line repair device. The line repair device includes a repair shell; a line connector is arranged in the repair shell; the line connector includes a middle connecting piece and two lock nuts; the two lock nuts are connected to both ends of the middle connecting piece in a threaded manner; each lock nut is provided with a tapered elastic sleeve; the entrance of a wire insertion hole is a corresponding tapered expansion structure; the upper surface of the repair shell is provided with a glue injection hole, and the liquidrepair glue can be injected into the repair shell through the glue injection hole; and the repair glue and repair shell together form a line repair insulation layer after the repair glue solidifies.The beneficial effects of the line repair device are as follows: the wire connection at the cable connection location is firm and reliable, and has a large current flow area; and the repair shell andthe solidified repair glue together form the repair insulation layer at the cable connection location; therefore, the water and moisture resistance is good, the strength is high and not easy to break,the cable can run effectively for a long time after connecting, and the service life of the cable is prolonged.

Description

technical field [0001] The invention relates to the technical field of electric tools, in particular to a circuit repairing device. Background technique [0002] In the process of power line repair, it is often necessary to connect two disconnected cables. When performing cable connection, the traditional method commonly used by maintenance workers is to twist the wires at the ends of the two disconnected cables together, and then connect the joints. Wrap seal with insulating tape. After a long period of operation and maintenance, it was found that the above-mentioned traditional method has some disadvantages. First, the wires at the joint are fixed by natural winding, which is not securely fixed, easy to loosen, and the operation is random, which is prone to excessive flow area at the joint. Second, the insulating tape cannot be well in close contact with the outer sheath of the cable, and the cable runs in a humid environment for a long time, and the gap between the wrapp...

After a long period of operation and maintenance, it was found that the above-mentioned traditional method has some disadvantages. First, the wires at the joint are fixed by natural winding, which is not securely fixed, easy to loosen, and the operation is random, which is prone to excessive flow area at the joint. Second, the insulating tape cannot be well in close contact with the outer sheath of the cable, and the cable runs in a humid environment for a long time, and the gap between the wrapped insulating tape and the outer sheath of the cable is prone to water, Ingress of moisture will lead to insulation failure at the connection position, causing safety hazards to the cables in operation; moreover, the strength of the wrapped insulating tape is poor, and it is easy to be damaged during the construction process, resulting in a decrease in insulation performance, and it is easy to enter water and get damp, which also causes safety hazards.
