Embodiment 1

[0026] The present embodiment is a kind of connecting clip of overhead power line, see Figure 1 to Figure 7 As shown, it includes a base body 1, a flat nut 2 and a set of pressure jaw assembly 3, the pressure jaw assembly includes three pressure jaws 4; the base body is provided with a slide tube 11, a radial guide limit hole 12 arranged on the slide tube and The block 13 that is arranged on the outer peripheral wall of the slide tube protrudes outward along the radial direction of the slide tube; the radial guide limit hole penetrates the tube wall of the slide tube along the radial direction of the base slide tube; the shape of the block is ring-shaped, and the block It is located at one end of the base sliding tube in the axial direction, and the radial guide limiting hole 12 is located at the other end of the base sliding tube in the axial direction;

[0027] The quantity of radial guide limit hole 12 is the same as the quantity of pressure jaw 4, also is three; Sliding ...

Embodiment 2

[0039] This embodiment is basically the same as Embodiment 1, the difference is: see Figure 8 to Figure 14 As shown, this embodiment also includes a mandrel 6 located in the lumen of the base slide tube; three arc-shaped clamping grooves 61 are arranged on the outer peripheral wall of the mandrel 6 along the central axis of the base tube, and each arc-shaped clamping groove is provided with Multiple punctures; each arc-shaped clamping groove is set opposite to the arc-shaped groove 45 on the inner wall of the corresponding one of the pressing jaws, and each arc-shaped clamping groove and the corresponding one arc-shaped groove are clamped to form a wire clamping hole 5, so this embodiment forms a total of Three clamping holes 5 can be used to clamp three cables at the same time;

[0040] The outer peripheral wall of the mandrel is provided with three supporting and positioning convex plates 62 protruding radially along the base sliding tube, and the inner peripheral wall of t...

Embodiment 3

[0042] This embodiment is basically the same as Embodiment 1, the difference is: see Figure 15 As shown, the length of the base slide tube in this embodiment is slightly longer, and a voltage transformer 7 is sheathed and fixed on the outer peripheral wall of the base slide tube. Since the power cable passes through the lumen of the base slide tube, the voltage transformer The device can obtain a lower induced voltage through induction, which can be used as a power supply for auxiliary equipment. For example, a camera with a wireless transceiver unit, a temperature sensor, a humidity sensor or a lightning strike counter and other auxiliary equipment can be fixedly installed on the lower part of the base slide tube to monitor the environment around the clamp in real time, and the real-time The information is sent to the remote host to provide basic data for the intelligentization of power lines; and the voltage transformer in this embodiment provides stable and sustainable pow...

Abstract

The invention discloses an overhead power line connection wire clamp, which comprises a base body, a flat nut and three press claws, wherein the base body is provided with a slide tube, a stopping table and three radial guide limiting holes; each press claw is located in one corresponding radial guide limiting hole; the flat nut sleeves the outer circumference wall of the slide tube of the base body; each press claw is provided with a press plate part, a guide slide block part and a drive thread part; a flat thread part, which is matched with the drive thread parts, is arranged at one side end, far away from the stopping table, of the flat nut; the flat nut drives the flat thread part thereof to rotate in a reciprocating manner, so that the press claws are driven to be close to one another towards the center of the slide tube or far away from one another through the drive thread parts; each drive thread part is arranged on the wall of one side end, adjacent to the flat nut, of one corresponding anti-drop part; the shape of each anti-drop part is matched with one corresponding anti-drop slide hole; the guide parts and the anti-drop parts of the press claws penetrate through the press claws along the radial direction of the slide tube of the base body; and each drive thread part is arranged on the wall of one side end, adjacent to the flat nut, of the corresponding anti-drop part in a protruding manner. The overhead power line connection wire clamp has an excellent anti-looseness effect.

Description

technical field [0001] The invention belongs to the technical field of electric power fittings for overhead lines, and in particular relates to a connection clip for overhead electric lines. Background technique [0002] In the construction of overhead power lines, when the cables need to be branched or spliced, it is necessary to connect two insulated wires together with power line splicing clamps. The power line connection clamp has the characteristics of easy installation, low cost, safety, reliability and maintenance-free. Cable branches can be made without cutting off the main cable or stripping the insulation layer of the cable. The joints are completely insulated and can be used for live work, and can be branched at any position on the cable; no terminal box or junction box is needed; and the joints are resistant to twisting, Shockproof, waterproof, anti-corrosion and aging; using insulated power line splicing clips as cable branches, the comprehensive benefits are o...
