Embodiment 1

[0020] This embodiment is a high-voltage power piercing clamp, see Figure 1 to Figure 5 As shown, it includes a base 1, two flat nuts 2 and two sets of pressing claw assemblies 3; each set of pressing claw assemblies includes three pressing claws 4; the base is provided with a sliding tube 11 and a radial guide limit set on the sliding tube The hole 12 and the stopper 13 formed on the outer peripheral wall of the slide tube and protruded outward in the radial direction of the slide tube; the radial guide and limit hole penetrates through the wall of the slide tube along the radial direction of the base slide tube; the shape of the stopper is ring , The stop is located at the middle end of the slide tube of the base;

[0021] The number of radial guide limit holes 12 is the same as the number of press claws 4, six in total, and three radial guide limit holes are provided at both ends of the base slide tube in the axial direction. The three radial guide limit holes It is used to f...

Embodiment 2

[0034] This embodiment is basically the same as embodiment 1, the difference lies in: see Figure 6 to Figure 10 As shown, this embodiment also includes a core rod 6 located in the lumen of the slide tube of the base body; two sets of pressing claw assemblies are symmetrically arranged at both ends of the slide tube; the outer peripheral wall of the core rod 6 is provided with three The arc-shaped clamping groove 61 is provided with a plurality of punctures in each arc-shaped clamping groove; each arc-shaped clamping groove is arranged directly opposite to the arc-shaped groove 45 on the inner wall of the corresponding pressing claw, and each arc-shaped clamping groove and a corresponding arc-shaped groove clamp One wire clamping hole 5 is formed together, so in this embodiment, three wire clamping holes 5 are formed, which can be used to clamp three cables at the same time;

[0035] The outer peripheral wall of the mandrel is provided with three supporting and positioning convex...

Embodiment 3

[0037] This embodiment is basically the same as embodiment 1, the difference lies in: see Picture 11 As shown, the axial dimension of the stop in this embodiment is relatively large. A positioning groove 131 is provided in the middle of the stop, and a ring-shaped voltage transformer 7 is also fixed in the positioning groove. The sliding tube passes through the lumen, and the voltage transformer can obtain a lower induced voltage through induction, and is 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 counter and other auxiliary equipment can be fixedly installed at the lower part of the slide tube of the substrate to monitor the environment around the clamp in real time, and the wireless transceiver unit can realize real-time monitoring The information is transmitted to the remote host to provide basic data for power line intelligence; the voltage transformer in thi...

Abstract

The invention discloses a high-voltage power puncture wire clamp, which comprises a base body, two flat nuts and two sets of press claw components, wherein each set of press claw components comprise three press claws; the base body is provided with a slide tube, a stopping table and radial guide limiting holes; each press claw is located in one corresponding radial guide limiting hole; each flat nut is matched with one corresponding set of press claw components and drives three press claws in one corresponding set of press claw components to be close to one another towards the center of the slide tube or far away from one another; a plurality of mounting clamping grooves for embedding puncture sheets are formed in the inner wall of each press plate part; each puncture sheet comprises a mounting part and a puncture blade part; each mounting part is embedded into the corresponding mounting clamping groove; each puncture blade part is exposed out of the corresponding mounting clamping groove to form one puncture; and the punctures protrude inwards along the radial direction of the slide tube of the base body. The high-voltage power puncture wire clamp is easy to install.

Description

Technical field [0001] The invention belongs to the technical field of overhead line power fittings, and specifically relates to a high-voltage power piercing clamp. Background technique [0002] In the construction of overhead power lines, when the cable needs to be branched or spliced, it is necessary to use splicing clamps to connect the two insulated wires together. The splice clamp, especially the puncture type splice clamp, has the characteristics of easy installation, low cost, safety, reliability and maintenance-free. The cable branch can be made without cutting off the main cable or stripping the insulation layer of the cable. The connector is fully insulated and can be operated on live lines. It can be branched at any position of the cable; no terminal box or junction box is required; and the connector is resistant to twisting, Shockproof, waterproof, anti-corrosion and aging; the comprehensive benefits are obvious, and the cost performance is better than the previous ...
