Description

Technical Field

[0001] The utility model relates to the technical field of electric power, and more specifically to a power line connector. Background Art

[0002] Power lines refer to the lines used to transmit electric energy between power plants, substations and power users. They are an important part of the power supply system and are responsible for the transmission and distribution of electric energy. In order to facilitate installation and disassembly, the wire joints are connected more tightly, and connectors are usually used to connect the two sections of wires.

[0003] A Chinese patent disclosed "a power line connector connector" with patent number CN202020019810.2. The scheme records "a power line connector connector, relating to the field of power technology, comprising a connecting cylinder, wherein the inner top wall of the connecting cylinder is fixedly connected with four mutually symmetrical limit columns." The utility model, by setting a slider, a connecting rod, a second slide groove, a support plate, a connecting shaft, a sliding column, a clamping plate, a second threaded rod, a second bearing and a first slide groove, can make the two sealing plugs move toward each other at the same time by rotating the second threaded rod, thereby clamping and fixing the cable, and by setting a support seat, the extrusion plate, the connecting plate, the spring, the limit column and the first slide groove are fixedly connected. Under the action of the positioning column, the first threaded rod and the first bearing, the extrusion plate can always have a good clamping effect on the joint of the two sections of the cable through the spring, which solves the problem that the joints of the two sections of the wires are prone to loosening during long-term use in most existing power line joint connectors, resulting in poor contact and safety hazards. However, there are still certain problems. When using this connector, the user needs to first pull open the sealing plugs at both ends of the connecting tube. After the connected wires are passed through, the first threaded rod and the two second threaded rods at three different positions need to be screwed respectively to achieve the clamping of the wires. The operation is cumbersome and will affect work efficiency. Utility Model Content

DETAILED DESCRIPTION

[0022] When using some existing connectors, the user needs to first pull open the sealing plugs at both ends of the connecting tube. After the connected wires are passed through, the user needs to screw a first threaded rod and two second threaded rods at three different positions in turn to clamp the wires.

When the movable frame 3 moves, the first sliding rod 7 can be driven to squeeze the inner wall of the inclined groove 6, and the inclined groove 6 is used to drive the clamping plate 5 to move in the second sliding groove 4. The inclined groove 6 is slidably connected to the inside of the first sliding rod 7, and the first sliding rod 7 is fixedly connected to the movable frame 3.

[0024] Limiting grooves 9 are provided inside the connecting tube 1 and on the corresponding two side edges of the clamping plate 5. The limiting grooves 9 are connected to the second sliding grooves 4. The limiting grooves 9 are internally slidably connected to the limiting blocks 10. The limiting blocks 10 are fixedly connected to the clamping plate 5.

[0029] The utility model uses the following steps: When using the power line connector, remove the protective skins of the two wires, wrap them together, wrap the connection with insulating tape, put the two wires into the opened connection tube 1, place the connection of the two wires inside the connection tube 1, and then rotate the upper connection tube 1 to close it. When the two connection tubes 1 are closed to each other, the movable frame 3 on the connection tube 1 will first contact and press tightly. As the two connection tubes 1 continue to close, the movable frame 3 is pressed into the first slide groove 2. During the process, the movable frame 3 drives the first slide bar 7 When the two connecting tubes 1 are fully closed, the two clamping plates 5 also cooperate with each other to clamp the wires, and the clamping block 16 also engages with the clamping groove 17. After the user puts the wires into the connecting tube 1, it only needs to close it.
