Embodiment 1

[0018] This embodiment is a kind of power clamping fittings to prevent the cable from loosening, see Figure 1 to Figure 7 As shown, it includes a jacking bolt 1 , a core tube 2 , a set of crimping assembly 3 and a set of pressing jaw assembly 8 .

[0019] The tube wall of the core tube is provided with a group of guide holes, and the group of guide holes includes four radial guide slide holes 22, and the four radial guide slide holes are evenly distributed on the core tube wall along the circumference of the core tube; The guiding sliding holes all penetrate the core tube wall along the radial direction of the core tube; each radial guiding sliding hole is located in the middle of the core tube in the axial direction, and the cross-sectional shape of each radial guiding sliding hole is I-shaped. An internal thread area 23 is provided in the lumen of the core tube.

[0020] The crimping assembly 3 includes four crimping parts 31; each crimping part is provided with a pressing...

Embodiment 2

[0035] This embodiment is basically the same as Embodiment 1, the difference is: see Figure 8As 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 The ring-shaped inductive sensing body and the intelligent control module are arranged side by side to form a ring shape, and the current transformer is sleeved and fixed on the outer wall of the pressing plate part as a whole, that is, the crimping assembly is located in the cavity of the current transformer as a whole. 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-sh...

Embodiment 3

[0039] This embodiment is basically the same as Embodiment 1, the difference is: see Figure 9 to Figure 10 As 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 pressing plate; the core tube Multiple accommodating cavities 73 are formed by sandwiching the outer wall, the crimping piece and the ring-shaped induction body, and the intelligent control module is arranged in the accommodating cavities. This structure can make full use of the space and is conducive to the overall small size and integration.

[0040] The intelligent control module can include a wireless transceiver unit, through which the intelligent control module transmits the leakage current signal sensed by the ring sensing body to the remote host, so as to realize precise remote unma...

Abstract

The invention discloses a power wire clamping fitting for preventing a cable from loosening. The power wire clamping fitting comprises a jacking and pressing bolt, a core tube, a crimping assembly and a press claw assembly, wherein radial guide slide holes are formed in the tube wall of the core tube; an inner thread region is arranged in a tube cavity of the core tube; the crimping assembly comprises a plurality of crimping parts; each crimping part is provided with a press plate part and an anti-drop connection part; the crimping parts are detachably arranged on the core tube through the anti-drop connection parts; the press claw assembly comprises a plurality of press claws; each press claw comprises a top plate part, a guide slide block part and a drive surface; each guide slide block part is inserted into one corresponding radial guide slide hole; the jacking and pressing bolt comprises a body, an outer thread region and a jacking and pressing boss; the shape of the jacking and pressing boss is a truncated cone shape; the outer thread region of the jacking and pressing bolt 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 one corresponding jacking and pressing boss; and the jacking and pressing bolt pushes the top plate parts to move outwards along the radial direction of the core tube when rotating along the preset direction. The power wire clamping fitting is firm, stable and reliable to install.

Description

technical field [0001] The invention belongs to the technical field of electric power fittings, and in particular relates to an electric power clamping fitting for preventing cables from loosening. 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...
