Embodiment 1

[0025] The present embodiment is a kind of overhead power line connection clip, 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;

[0026] The quantity of radial guide limit hole 12 is the same as the quantity of pressure jaw 4, also is three; Sliding rec...

Embodiment 2

[0038] 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;

[0039] 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

[0041] 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 a wire clamp for splicing an overhead power line. The wire clamp comprises a base body, a nut and three pressing claws, wherein the base body is provided with a sliding tube, a baffle table and three radial guiding limiting holes; each pressing claw is positioned in one corresponding radial guiding limiting hole; a planar nut is arranged on the outer circumferential wall of the base body sliding tube in a sleeving manner; each pressing claw is provided with a plate pressing part, a guiding sliding block part and a driving threaded part; a planar threaded part adapted with the driving threaded part is arranged on one side end, far from the baffle table, of the planar nut; the planar nut drives the planar threaded part to move in a reciprocating manner so as to further drive each pressing claw through the driving threaded part to move towards the center of the base body sliding tube in a manner of being close to each other or far away from each other; each radial guiding limiting hole comprises a rectangular sliding hole and an anti-dropping sliding hole; the rectangular sliding hole is formed in the edge, far from the baffle table, of the base sliding tube to form a nick; and the anti-dropping sliding hole is communicated with the rectangular sliding hole. The wire clamp has an excellent anti-loosening 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...
