Embodiment 1)

[0023] This embodiment is a kind of power connection fittings with higher clamping strength, see Figure 1 to Figure 7 As shown, it includes a base pipe 1 , a core pipe 2 , a crimping piece 3 and a set of pressing jaw assemblies 9 .

[0024] The inner peripheral wall of the base pipe is provided with a plurality of clamping bosses 11, and the inner wall of each clamping boss is provided with arc-shaped grooves 111, and each wire-holding boss and arc-shaped grooves extend axially along the base tube. The inner peripheral wall of the base pipe is also provided with a plurality of positioning sliding grooves 12 along the axial direction of the base pipe.

[0025] The core tube and the base tube are arranged concentrically, and the core tube is located in the lumen of the base tube; the outer peripheral wall of the core tube is provided with a plurality of supporting convex plates 21 protruding radially along the base tube, and the outer ends of each supporting convex plate are lo...

Embodiment 2)

[0038] This embodiment is basically the same as Embodiment 1, the difference is: see Figure 8 and Figure 9 As shown, the base pipe 1 is provided with a mounting screw hole 18 that penetrates the wall of the clamping boss 11 along the radial direction of the base pipe; a temperature sensing device 8 is fixed in the mounting screw hole;

[0039] The temperature sensing device includes a metal housing 81 made of metal material with a containing groove 811, a temperature sensor 82 arranged in the containing groove, a spring 83 for crimping the temperature sensor on the bottom wall of the containing groove, Coil plug 84 for limit spring;

[0040] One end 812 of the metal shell close to the central axis of the base 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 base tube is provided with an inner hexagonal screw groove 815; There is an external thread 816 adapted to the mounting screw hole...

Embodiment 3)

[0048] This embodiment is basically the same as Embodiment 2, the difference is: see Figure 10 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 Shaped, ring-shaped inductive induction body and intelligent control module are arranged side by side to form a ring shape, and the current transformer is integrally sleeved and fixed on the outer peripheral wall of the base pipe. 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-shaped induction body The cavity is enough.

[0049] In this embodiment, the inner periphe...

Description

technical field [0001] The invention belongs to the technical field of electric power fittings, and in particular relates to an electric connecting fitting with high clamping strength. 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 t...
