Embodiment 1

[0018] This embodiment is a splicing clip for overhead lines, see Figure 1 to Figure 6 As shown, it includes a core tube 2, a set of pressing jaw assembly 3, a flat nut 4 and three crimping parts 1.

[0019] The tube wall of the core tube is provided with three radial limiting sliding holes 22, and each radial limiting sliding hole runs through the core tube tube wall along the radial direction of the core tube; each radial limiting sliding hole is located on the axial direction of the core tube. In the middle part, the radial cross-sectional shape of each radial limit hole is I-shaped; the inner peripheral wall of the core tube is provided with an inwardly protruding annular stopper 23 .

[0020] Each crimping piece is provided with a pressing plate portion 11 and an anti-off connecting portion 12; the crimping piece is detachably arranged on the core tube through the anti-off connecting portion; the pressing plate portion 11 extends axially along the core tube, and the inne...

Embodiment 2

[0033] This embodiment is basically the same as Embodiment 1, the difference is: see Figure 7 to Figure 10 As shown, a current transformer 8 is sleeved and fixed on the outer peripheral wall of each crimping piece in this embodiment; the current transformer 8 includes an annular base 81 and an intelligent control module 82, and the intelligent control module may include a wireless transceiver unit. When there is a leakage current in the three power cables, the ring base will induce a secondary current, and the intelligent control module will transmit the secondary current information to the remote host through the wireless transceiver unit; the intelligent control module is set on the inner wall of the ring base and the outer wall of the core tube. In the area enclosed by the outer wall of the crimping part, the space is fully utilized, which is beneficial to the overall small size and integration.

[0034] This embodiment as a whole can be used as a high-voltage zero-sequence ...

Abstract

The invention discloses a wire clamp for splicing an overhead line. The wire clamp comprises a base tube, a set of pressing claw assembly, a planar nut and a crimping part, wherein the crimping part is provided with a plate pressing part and an anti-dropping connecting part; the crimping part is detachably arranged on the core tube through the anti-dropping connecting part; the plate pressing part is positioned outside the core tube; radial limiting sliding holes are formed in the tube wall of the core tube; the pressing claw assembly comprises pressing claws that are combined with the crimping part to form cable-clamping holes; each pressing claw comprises a top plate part, a guiding sliding block part and a driving threaded part; the top plate part is positioned outside the core tube; each guiding sliding block part is inserted into one corresponding radial limiting sliding hole of the core tube; each driving threaded part extends to the tube cavity of the core tube; the planar nut is rotationally arranged in the tube cavity of the core tube; the planar nut comprises a planar threaded part that is meshed and adapted with the driving threaded part of each pressing claw; and the planar nut drives the pressing claws to move to be close to each other towards the center of the core tube or far away from each other. 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 clamp for overhead 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 a splicing clamp for overhead lines. The splicing clamp for overhead lines 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 splicing clips for insulated overhead lines as cable branches has obvious compre...
