Description

Technical Field

[0001] The utility model belongs to the technical field of cable joint protection components, and particularly relates to a cable joint protection component for power engineering. Background Technique

[0002] A cable joint is also called a cable head. After the cable is laid, in order to make it a continuous line, each section of the line must be connected as a whole, and these connection points are called cable joints. The cable joint in the middle part of the cable line is called an intermediate joint, while the cable joints at both ends of the line are called terminal heads. The cable joint is used to lock and fix the incoming and outgoing lines, and plays the role of waterproof, dustproof and anti-vibration.

[0003] However, in the existing mechanisms, most of the cable joint protection components for power engineering cannot accurately and stably clamp the two connectors when fixing them, which will cause loosening at the connection, resulting in problems such as poor contact, increased resistance, and heat generation, seriously affecting the transmission efficiency and safety of the power line, and may pose serious potential safety hazards. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a cable joint protection component for power engineering. By setting a clamping mechanism, the first connector and the second connector protect the connection of the cable, greatly improving the overall stability and reliability, and also preventing accidental separation or loosening, ensuring the safety of the connection, and solving the problem that it cannot be accurately and stably clamped, which will cause loosening at the connection, resulting in problems such as poor contact, increased resistance, and heat generation.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model is a cable joint protection component for power engineering, including a first connector and a second connector. The first connector is provided with a clamping mechanism and a connection mechanism. The clamping mechanism includes a clamping component and an engaging component;

[0007] The clamping component includes a plurality of external tooth grooves opened on the outer wall of the second connector. Two fixed frames are fixedly connected to the outer wall of the first connector. Two sliding rails are fixedly connected to the inner walls of the two fixed frames.

The outer walls of the two sliders are both slidably connected with the inner walls of the two fixed frames. Arc-shaped clamping rings are fixedly connected to the sides of the two sliders close to each other. A plurality of internal tooth grooves are opened on the inner walls of the two arc-shaped clamping rings. The plurality of internal tooth grooves are respectively adapted to the plurality of external tooth grooves.

[0008] Furthermore, the meshing assembly includes two gears that are both rotatably connected to the inner walls of the two fixed frames. Two racks are fixedly connected to the left sides of the two sliders, and several of the racks are respectively meshed with several of the gears.

[0009] Furthermore, the connecting mechanism includes a hinged assembly, a connecting assembly, and a limiting assembly. The hinged assembly includes eccentric shafts that are fixedly connected to several of the gears, and hinged rods are rotatably connected to several of the eccentric shafts.

[0010] Furthermore, a rotating rod is fixedly connected between corresponding two hinged rods. Hinged blocks are rotatably connected to the outer walls of the two rotating rods, and threaded rods are fixedly connected to the left sides of the two hinged blocks.

[0011] Furthermore, the connecting assembly includes two fixing plates fixedly connected to the outer wall of the first connection head, and the two threaded rods respectively slide through the two fixing plates.

[0014] The utility model has the following beneficial effects:

[0015] 1. By providing a clamping mechanism, after the inner tooth groove is inserted into the outer tooth groove, the two arc-shaped clamping rings can clamp and fix the position of the second connection head, so that after the connection block is inserted into the connection groove, the first connection head and the second connection head can be firmly fixed together, protecting the connection part of the cable by the first connection head and the second connection head, greatly improving the overall stability and reliability, and also preventing accidental separation or loosening, ensuring the safety of the connection.

[0016] 2. By providing a connection mechanism, the eccentric shaft, hinge rod, rotating rod, and hinge block cooperate with each other. When the threaded rod moves to the left, the gear can be driven to rotate through the hinge rod, causing the two sliders to move away from each other, so that the two arc-shaped clamping rings move away from the external tooth groove.
