Problems solved by technology

The problems of the above two methods are: 1. The connection is mainly manual operation, the connection effect is affected by the construction site equipment and human operation, the effect varies from person to person, the reliability of the connection cannot be guaranteed, and it takes a long time to increase the work of the staff 2. Terminal crimping is often only the crimping part as the contact surface, the contact area is smaller than the nominal cross-section of the conductor, and the over-current capacity cannot meet the requirements; 3. It will loosen after thermal expansion and contraction, and it is easy to generate heat due to over-current Phenomenon, and even the failure of burning the connection, causing power outages and more serious accidents, resulting in huge economic losses

Embodiment 1

[0045] This embodiment provides a line repair device, such as Figure 1-4 As shown, it includes a connecting conductor 6, two elastic compression members 2, two expansion members 4, and two spin caps 5 respectively arranged on both sides of the connecting conductor 6. Reference image 3 with Figure 4 Specifically, the two ends of the connecting conductor 6 are provided with mounting holes 63, and the two wires 101 are respectively arranged in the two mounting holes 63 and can be electrically connected with the connecting conductor 6; the two expansion members 4 are respectively sleeved on the two wires 101 Above, the expansion member 4 is in the shape of a conical column and its large diameter end is close to the connecting conductor 6; the two compression elastic members 2 are respectively arranged in the two mounting holes 63, and their two ends are respectively abutted on the large diameter end of the expansion member 4 And the connecting conductor 6; two screw caps 5 are r...

Embodiment 2

[0067] The difference between this embodiment and the first embodiment is that a two-wire system or a multi-wire system is formed. In this embodiment, the line repairing device includes a plurality of insulating housings 1, and the plurality of insulating housings 1 are connected by an insulating plate 16; other embodiments In this case, a plurality of accommodating cavities may also be opened on the insulating housing 1, and each accommodating cavity is used to connect two wires 101.

Abstract

The invention discloses a line repairing device, and belongs to the technical field of power maintenance tools. The line repairing device comprises a connecting conductor, two packing elastic pieces,two expansion pieces and two turncaps, mounting holes are formed in the two ends of the connecting conductor, and two wires are arranged in the two mounting holes respectively and can be electricallyconnected with the connecting conductor; and the two expansion pieces respectively sleeve the two wires, the expansion pieces are in a conical column shape, and the large-diameter ends of the expansion pieces are close to the connecting conductor. The two packing elastic pieces are arranged in the two mounting holes respectively, and the two ends of each packing elastic piece abut against the large-diameter end of the expansion piece and the connecting conductor respectively; and the two turncaps are connected to the two ends of the connecting conductor respectively, the turncaps are arrangedon the expansion piece in a sleeving mode, and inner cavities of the turncaps are in a conical hole shape matched with the appearance of the expansion piece. According to the line repairing device provided by the invention, the expansion piece is compressed from the two ends by the compression elastic piece and the turncap, so that the expansion piece is tightly attached to the wire, the overcurrent capacity is improved, the wire is prevented from loosening, and the connection reliability is improved.

Description

Technical field [0001] The invention relates to the technical field of electric power maintenance tools, in particular to a line repair device. Background technique [0002] The low-voltage overhead line is an important channel connecting the platform and the user end. There are a large number of cable terminals and connectors. The stability and reliability of the connector connection are essential for safe electricity use. When repairing power lines, the prior art usually adopts: hand-tie type, in which insulating tape is wound on the outside of the connection point for waterproof and insulation protection; terminal crimping type, heat shrinkable sleeve is used after the terminal is crimped to realize the cable connection Insulate and waterproof. The problems of the above two methods are: 1. The connection is mainly manual operation, and the connection effect is affected by the construction site equipment and human operation. The effect varies from person to person. The reliabi...
