Embodiment 1）

[0017] This embodiment is an improved connecting fitting for overhead lines, see Figure 1 to Figure 5 As shown, it includes a base tube 1, a core tube 2, two sets of pressing jaw assemblies 3 and two flat nuts 4; the inner peripheral wall of the base tube is provided with a plurality of crimping bosses 11 along the axial direction of the base tube, and each crimping The inner wall of the boss is provided with an arc-shaped groove 111; the inner peripheral wall of the base tube is also provided with a plurality of positioning slide grooves 12 along the axial direction of the base tube; the core tube and the base tube are arranged concentrically and are located in the lumen of the base tube; The wall is provided with a plurality of supporting convex plates 21 protruding and extending radially along the core tube, and 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...

Embodiment 2）

[0029] This embodiment is basically the same as Embodiment 1, the difference is: see Image 6 and Figure 7 As shown, the base pipe 1 is provided with a mounting screw hole 15 radially penetrating through the wall of the base pipe; a temperature sensing device 8 is fixed in the mounting screw hole.

[0030] 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 pipe plug 84 that is used for limit spring.

[0031] 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; There is an external thread 816 adapted to the mounting screw hole, and an ...

Embodiment 3）

[0039] This embodiment is basically the same as Embodiment 2, the difference is: see Figure 8 As shown, a current transformer 9 is sleeved and fixed on the outer peripheral wall of the base pipe in this embodiment, and the current transformer 9 includes a ring-shaped induction body 91 and an intelligent control module 92; the overall shape of the intelligent control module is also ring-shaped; the ring-shaped induction The main body 91 and the intelligent control module 92 are arranged side by side.

[0040] The inner peripheral wall of the intelligent control module 92 is provided with two sockets protruding inward (not shown in the figure), and each socket is inserted into a corresponding socket, so that the temperature sensor and the intelligent control module connected to the central control circuit in the

[0041] When the number of crimping bosses and pressing claws in this embodiment is three, this embodiment can form three clamping holes for clamping three phase cabl...

Abstract

The invention discloses an improved splicing fitting used for an overhead line. The improved splicing fitting comprises a base tube, a core tube, two sets of pressing claw components and two plane nuts. The internal circumferential wall of the base tube is provided with crimping bosses. The tube wall of the core tube is provided with radial limiting slide holes. The internal circumferential wall of the core tube is provided with a blocking stand. Each set of pressing claw component comprises multiple pressing claws. The two plane nuts are rotatably arranged in the tube cavity of the core tube. The two plane nuts are respectively arranged at the two sides of the blocking stand. Each plane nut comprises a fastening part and a plane thread part which is adaptive to each pressing claw of one corresponding set of pressing claw component. The base tube is provided with installing screw holes which penetrate through the wall body of the base tube along a radial direction. The base tube is provided with the installing screw holes which are internally provided with a temperature sensing device. The improved splicing fitting used for the overhead line 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 an improved connecting fitting for overhead lines. Background technique [0002] In the construction of overhead power lines, when the cables need to be branched or connected, it is necessary to use power line connecting fittings to connect two insulated conductors together. Power line connection 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 insulated power line connection fittings as cable branches, the comp...
