Embodiment 1

[0015] This embodiment is a high-voltage power connection fitting with better clamping fastness, see Figure 1 to Figure 5 As shown, it includes a base pipe 1 , a core pipe 2 , two sets of pressing jaw assemblies 3 and a flat nut 4 .

[0016] The inner peripheral wall of the substrate tube is provided with a plurality of crimping bosses 11 along the axial direction of the substrate tube, and the inner wall of each crimping boss is provided with arc-shaped grooves 111; the inner peripheral wall of the substrate tube is also provided with a plurality of positioning The chute 12; the core tube and the base tube are arranged concentrically and are 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 extending radially along the core tube, and the outer ends of each supporting convex plate Located in a corresponding positioning chute, so that the core tube is supported and positioned in the lum...

Embodiment 2

[0029] This embodiment is basically the same as Embodiment 1, the difference is: see Image 6 As shown, in this embodiment, a current transformer 8 is sleeved and fixed on the outer peripheral wall of the base pipe, and the number of the crimping bosses and claws is three, so this embodiment can form three clamping holes , for clamping the three phase cables. At this time, this embodiment as a whole can be used as a high-voltage zero-sequence current transformer to detect the existence of leakage current and find leakage faults in time.

Abstract

The invention discloses a high-voltage power connection fitting with relatively good wire clamping fastness. The high-voltage power connection fitting comprises a base body, a core tube, two sets of press claw components and a flat nut, wherein crimping bosses are arranged on the inner circumference wall of the base tube; radial limiting slide holes are formed in the tube wall of the core tube; each set of press claw components comprise a plurality of press claws; various press plate parts and one corresponding crimping boss are clamped to form a wire clamping hole; plane thread parts are arranged at two side ends of the flat nut along the axial direction of the core tube respectively; a fastening part is arranged at the center of the flat nut; the plane thread parts are meshed and matched with the drive thread parts of various press claws in one corresponding set of press claw components; the flat nut drives the two plane thread parts to rotate in a reciprocating manner, and synchronously drives the press claws in the two sets of press claw components to be close to or far away from the center of the core tube. The high-voltage power connection fitting has a relatively good anti-looseness effect.

Description

technical field [0001] The invention belongs to the technical field of electric power fittings for overhead lines, and in particular relates to a high-voltage electric connecting fitting with better clamping fastness. 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 cab...
