Embodiment 1）

[0020] This embodiment is a puncture wire clip for power transmission and distribution, see Figure 1 to Figure 8 shown,

[0021] It includes a base pipe 1, a core pipe 2, a set of pressing claw assemblies 3 and a flat nut 4; the inner peripheral wall of the base pipe is provided with a plurality of crimping bosses 11 along the axial direction of the base tube, and the inner wall of each crimping boss is An arc-shaped groove 111 is provided; the inner peripheral wall of the base pipe is also provided with a plurality of positioning chute 12 along the axial direction of the base pipe; the outer peripheral wall of the core pipe is provided with a plurality of supporting convex plates 21 that protrude and extend along the radial direction of the base pipe , the outer end of each supporting convex plate is located in a corresponding positioning chute, so that the core tube is supported and positioned in the lumen of the base tube; the core tube and the base tube are concentrically...

Embodiment 2）

[0033] This embodiment is basically the same as Embodiment 1, the difference is: see Figure 9 and Figure 10 As shown, the base pipe 1 is provided with a mounting screw hole 15 which penetrates the wall of the base pipe in the radial direction; a temperature sensing device 8 is fixed in the mounting screw hole.

[0034] The temperature sensing device 8 includes a metal casing 81 made of a metal material with an accommodating groove 811, a temperature sensor 82 disposed in the accommodating groove, and a spring 83 for crimping the temperature sensor on the bottom wall of the accommodating groove , The coil plug 84 for the limit spring.

[0035] One end 812 of the metal shell close to the central axis of the core tube is provided with a heat-conducting boss 813 for puncturing, 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; There is an external thread 816 adapted to the mounting screw hole, a...

Embodiment 3）

[0043] This embodiment is basically the same as embodiment 2, the difference is: see Figure 11 As shown, in this embodiment, a current transformer 9 is also sleeved and fixed on the outer peripheral wall of the base pipe. The current transformer 9 includes an annular induction body 91 and an intelligent control module 92; the overall shape of the intelligent control module is also annular; the annular induction The body 91 and the intelligent control module 92 are arranged side by side.

[0044] When the number of the crimping bosses and the crimping claws in this embodiment is three, this embodiment can form three wire clamping holes for clamping three-phase cables. At this time, the whole embodiment can be used as a high-voltage zero The sequence current transformer is used to detect the existence of leakage current and find the leakage fault in time.

[0045] The inner peripheral wall of the intelligent control module 92 is provided with two inwardly protruding electrical...

The invention has excellent anti-loosening effect.

Description

technical field [0001] The invention belongs to the technical field of overhead line power fittings, in particular to a puncture wire clip for power transmission and distribution. Background technique [0002] In the construction of overhead power lines, when the cable needs to be branched or connected, it is necessary to connect the two insulated wires together with a puncture clip for power transmission and distribution. The puncture wire clip for power transmission and distribution 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 joint is completely insulated, and can be operated live, and can be branched on-site at any position of the cable; no terminal box and junction box are required; and the joint is resistant to twisting, Anti-shock, waterproof, anti-corrosion and aging; using puncture clips for insul...
