Embodiment 1

[0020] This embodiment is a kind of electric clamp wire fittings, see Figure 1 to Figure 6 As shown, it includes a base 1 , a pressure ring 2 and a set of pressure jaw assemblies 3 .

[0021] The base body 1 includes a base pipe part 11 provided with an internally threaded area 111, a core pipe part 12 arranged in the lumen of the base pipe, and a connecting plate part 13 for connecting and fixing the base pipe part and the core pipe part; the base pipe part and the core The tube parts are arranged concentrically, and the connecting plate part is an annular plate located between the base tube part and the core tube part. In this embodiment, the connecting plate part is located at the edge of the same side of the base tube part and the core tube part; The structural shape only needs to satisfy the fixed connection between the base pipe part and the core pipe part.

[0022] The base pipe part, the core pipe part and the connecting plate part in this embodiment are integral par...

Embodiment 2

[0037] This embodiment is basically the same as Embodiment 1, the difference is: see Figure 7 to Figure 11 As shown, this embodiment also includes a mandrel 7 located in the lumen of the core tube part; four arc-shaped clamping grooves 71 are provided on the outer peripheral wall of the mandrel, each arc-shaped clamping groove extends axially along the core tube part, each The arc-shaped clamping grooves are arranged opposite to the arc-shaped grooves on the inner wall of the corresponding one of the pressure jaws; each arc-shaped clamping groove and a corresponding arc-shaped groove are clamped to form a clamping hole 4; so this embodiment can form four clamping holes, Can be used to clamp four cables simultaneously.

[0038] The outer peripheral wall of the mandrel is provided with four supporting positioning convex plates 72 protruding along the radial direction of the core tube part, and the inner peripheral wall of the core tube part is provided with four positioning sli...

Embodiment 3

[0040] This embodiment is basically the same as Embodiment 1, the difference is: see Figure 12 As shown, this embodiment also includes a voltage transformer 8; the voltage transformer includes an annular induction body 81 and an intelligent control module; in this embodiment, the connecting plate is provided with an annular groove, and the annular induction body of the voltage transformer and the intelligent control module The control module is fixed in the annular groove. In specific practice, the voltage transformer can also be fixedly arranged on the tube wall of the core tube part, as long as the clamping hole is located in the cavity of the ring-shaped induction body, that is, it is only necessary to make the cable pass through the ring-shaped induction body The cavity is enough.

[0041]The intelligent control module can include a wireless transceiver unit, through which the intelligent control module transmits the secondary voltage or current signal sensed by the annu...

Abstract

The invention discloses an electric power wire trapping fitting. The wire trapping fitting comprises a matrix, a press ring and a press claw assembly, wherein the matrix comprises a base tube part with an internal thread region, a core tube part and a connecting plate part; a plurality of guide sliding holes are formed in the wall of the core tube part; the press claw assembly comprises a plurality of press claws; each press claw is provided with a press plate part and a guide sliding column part; the guide slicing column parts are protruded from the press plate part for molding; a stress bevel is arranged at the top end of each guide sliding column part; the press plate part of each press claw is positioned in the cavity of the core tube part; each guide sliding column part penetrates a corresponding guide sliding hole, extends out of the core tube part and is positioned in the cavity of the base tube part; the press ring comprises a conical crimping surface on the internal wall of the press ring and an external thread region arranged on the external wall of the press ring; the conical crimping surface of the press ring is crimped on the stress bevel of each press claw, and the external thread region of the press ring is adaptive to the internal thread region of the base tube part; and the press ring pushes and presses the press plate part of each press claw to move toward the center of the core tube part. The wire trapping fitting has excellent mechanical electrical performance.

Description

technical field [0001] The technical field of electric power fittings for overhead lines of the present invention, in particular relates to a kind of electric wire clamping fittings. 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 tradi...
