Embodiment 1）

[0022] This embodiment is a clamping fitting for power lines, see Figure 1 to Figure 5 As shown, it includes a core tube 2 , two jacking bolts 1 , two sets of crimping assemblies 3 and two sets of pressing claw assemblies 9 .

[0023] Two groups of guide holes are arranged on the tube wall of the core tube, and the two groups of guide holes are arranged side by side along the axial direction of the core tube; each group of guide holes includes four radial guide slide holes 22, and the four radial guide slide holes The circumferential direction of the tube is evenly distributed on the tube wall of the core tube; each radial guiding slide hole runs through the tube wall of the core tube along the radial direction of the core tube; the cross-sectional shape of each radial guiding sliding hole is I-shaped. There are two internally threaded areas 23 in the lumen of the core tube.

[0024] Each set of crimping components 3 includes four crimping parts 31; each crimping part is pro...

Embodiment 2）

[0039] This embodiment is basically the same as Embodiment 1, the difference is: see Figure 6 to Figure 7 As shown, at least one crimping member 31 is provided with a mounting screw hole 315 penetrating through the wall of the pressing plate portion 311 in the radial direction of the core tube; a temperature sensing device 8 is fixedly installed in the mounting screw hole.

[0040] The temperature sensing device 8 includes a metal housing 81 made of metal material with a containing groove 811, a temperature sensor 82 arranged in the containing groove, and a spring 83 for crimping the temperature sensor on the bottom wall of the containing groove , The screw tube plug 84 that is used for limit spring.

[0041] One end 812 of the metal shell close to the central axis of the core tube is provided with a heat conduction boss 813 used as a puncture, and one end 814 of the metal shell away from the central axis of the core tube is provided with an inner hexagonal screw groove 815; ...

Embodiment 3）

[0049] This embodiment is basically the same as Embodiment 1, the difference is: see Figure 8 As shown, this embodiment also includes a current transformer 7; the current transformer includes an annular induction body 71 and an intelligent control module 72; in this embodiment, the intelligent control module 72 is made into a ring with the same size cavity as the annular induction body The ring-shaped inductive sensing body and the intelligent control module are arranged side by side to form a ring shape, and the current transformer is sleeved and fixed on the outer wall of the pressing plate part as a whole, that is, the crimping assembly is located in the cavity of the current transformer as a whole. In practice, the current transformer can also be fixedly arranged on the tube wall of the core tube, as long as all the clamping holes are located in the cavity of the ring-shaped induction body, that is, it is only necessary to make the cable pass through the hole of the ring-s...

Abstract

The invention discloses a wire clamping fitting for power lines, which comprises a core tube, two pressing bolts, two sets of crimping assemblies and two sets of pressing claw assemblies; the tube wall of the core tube is provided with a radial guide sliding hole ; Each crimping piece is provided with a pressure plate part and an anti-off connection part; the crimping part is detachably arranged on the core tube through the anti-off connection part; each set of pressure claw components includes a plurality of pressure claws; each pressure claw includes a top plate part, Guide the slider part and the driving surface; the top plate part of each pressure jaw is set directly against the pressure plate part of a corresponding crimping part; two pressure bolts are located on both sides of the core tube; each pressure bolt includes a body, an external thread area and a top Pressing boss, the shape of the top pressing boss is a truncated cone; the driving surface of each pressing claw is adapted to the outer peripheral wall of a corresponding top pressing boss; at least one crimping part is provided with a mounting screw hole for a built-in temperature sensing device ; When each pressing bolt rotates in a preset direction, each pressing jaw in a corresponding set of pressing jaw assembly is pushed to move. The invention is easy to install.

Description

technical field [0001] The invention belongs to the technical field of electric power fittings, and in particular relates to a wire clamping fitting for 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 use fittings to connect two insulated conductors together. Fittings have 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 insulating fittings as cable branches, the comprehensive benefits are obvious, and the cost performance is better than the traditional conne...
