Embodiment 1）

[0017] This embodiment is a connection fitting for overhead lines, see Figure 1 to Figure 4 As shown, it includes a core tube 2, two sets of pressing jaw assemblies 3, a flat nut 4 and two sets of crimping assemblies.

[0018] The tube wall of the core tube is provided with six radial limiting sliding holes 22, and each radial limiting sliding hole runs through the core tube tube wall along the radial direction of the core tube; each radial limiting sliding hole is located in the axial direction of the core tube. In the upper middle part, the radial cross-sectional shape of each radial limiting hole is I-shaped. In this embodiment, the six radial limiting holes are divided into two groups, and the three radial limiting holes in each group are used for matching with a corresponding set of pressing jaw assemblies.

[0019] Each set of crimping components is used to adapt to a corresponding set of pressing jaw components, and each set of crimping components includes three crimp...

Embodiment 2）

[0034] This embodiment is basically the same as Embodiment 1, the difference is: see Figure 5 to Figure 6 As shown, at least one crimping piece 1 is provided with a mounting screw hole 15 penetrating through the pressing plate part in the radial direction of the core tube; a temperature sensing device 8 is fixed in the mounting screw hole.

[0035] 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 tube plug 84 that is used for limit spring.

[0036] 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 a...

Embodiment 3）

[0044] This embodiment is basically the same as the above-mentioned embodiment 2, the difference is: see Figure 7 and Figure 8 As shown, in this embodiment, a current transformer 9 is sheathed and fixed on the outer peripheral wall of the crimping member, and the current transformer 9 includes a ring-shaped induction body 91 and an intelligent control module 92 .

[0045] The intelligent control module is provided with two electrical sockets protruding inward (not shown in the figure), and each electrical socket is inserted into a corresponding electrical socket, so that the temperature sensor and the central control circuit in the intelligent control module connected.

[0046] In this embodiment, a part of the intelligent control module is arranged in the area enclosed by the inner wall of the annular base, the outer wall of the core tube and the outer wall of the crimping piece, so as to make full use of the space and facilitate the overall compactness and integration.

Abstract

The invention discloses a matching armor clamp for an overhead line. The armor clamp comprises a core tube, two sets of pressing claw assemblies, two plane nuts and at least one pressing part, wherein the inner circumferential wall of the core tube is equipped with a pressing boss, a radial limiting slide hole is formed in the tube wall of the core tube, and a blocking platform is disposed on the inner circumferential wall of the core tube; each set of pressing claw assembly comprises multiple pressing claws; the two plane nuts are disposed in the tube chamber of the core tube in a rotatable manner, and the two plane nuts are located on two side of the blocking platform respectively; each plane nut comprises a fastening part and a plane threaded part which is matched with each pressing claw in the corresponding pressing claw assembly; and at least one pressing part is equipped with an installation screw hole which comprises a built-in temperature sensing device. The armor clamp disclosed by the invention has a function of real-time temperature monitoring.

Description

technical field [0001] The invention belongs to the technical field of electric power fittings for overhead lines, and in particular relates to a 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 comprehensive ...
