Embodiment 1

[0018] This embodiment is a kind of splicing fitting with higher clamping strength, see Figure 1 to Figure 7 As shown, it includes a base pipe 1 , a core pipe 2 , a crimping part 3 and a set of pressing jaw assemblies 8 .

[0019] 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.

[0020] 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 located at c...

Embodiment 2

[0033] 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 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.

[0034] The intelligent control module may inc...

Embodiment 3

[0037] This embodiment is basically the same as Embodiment 1, the difference is: see Figure 9 to Figure 10As shown, this embodiment also includes a current transformer 7; the current transformer includes a ring-shaped induction body 71 and an intelligent control module 72; in this embodiment, the ring-shaped inductive induction body is sleeved and fixed on the outer peripheral wall of the base pipe; The outer peripheral wall of the tube is provided with a wiring hole 13 that runs through the tube wall in the radial direction; the inner wall of the base tube, the outer wall of the core tube, the wire clamping boss, the supporting convex plate, and the pressing jaw pressing plate are sandwiched to form a plurality of accommodation cavities 73, The intelligent control module is arranged in the accommodating cavity; the electrical connection wire between the annular induction body and the intelligent control module passes through the wiring hole. This structure can make full use ...

Abstract

The invention discloses a connecting fitting with relatively high wire clamping strength. The connecting fitting comprises a base tube, a core tube, a crimping element and a press claw component, wherein a plurality of wire clamping bosses are arranged on the inner circumference wall of the base tube; the core tube is located in a tube cavity of the base tube; radial limiting slide holes are formed in the tube wall of the core tube; an inner thread region is arranged on the inner wall of the core tube; the press claw component comprises a plurality of press claws; each press claw comprises a press plate part, a guide slide block part and a drive surface; the crimping element comprises a body, an outer thread region and a crimping boss; the outer thread region is arranged on the outer circumference wall of the body; the crimping boss is arranged at the inner side end of the columnar body; the outer thread region of the crimping element is matched with the inner thread region of the core tube; the drive surface of each press claw is matched with the outer circumference wall of the crimping boss; the crimping element drives the crimping boss to rotate and advance towards the tube cavity of the core tube when rotating along the preset direction; the crimping boss pushes the press claws by pushing the drive surfaces, so that the press plate parts move outwards along the radial direction of the core tube to clamp power cables in wire clamping holes. The connecting fitting has relatively good mechanical and electric properties.

Description

technical field [0001] The invention belongs to the technical field of electric power fittings, and in particular relates to a splicing 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 traditional con...
