Line repair equipment

Abstract

The invention relates to the cable maintenance field and especially relates to line repair equipment. The equipment comprises a repair shell. A line connector is arranged in the repair shell. The lineconnector includes a middle connection component and two lock nuts. The two lock nuts are connected to two ends of the middle connection component in a threaded connection mode. A tapered elastic sleeve is arranged in each lock nut. An inlet of a plug wire hole is a corresponding tapered expansion structure. The equipment has advantages that lead connection at a connection portion of a cable is firm and reliable and an over-current area is large; the repair shell covers an outer portion of a cable connection portion and is taken as a repair insulation layer so that a water-proof and moisture-proof property is good, strength is high and the equipment is not easy to be damaged; and the cable can effectively operate for a long time after being connected, and a service life of the cable is prolonged.

Description

technical field [0001] The invention relates to the technical field of power tools, in particular to a line 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 wrapped ins...

Problems solved by technology

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.
