specific Embodiment approach 1

[0020] Specific implementation mode one: refer to Figure 1 to Figure 5 Describe this embodiment in detail, a method for connecting a telescopic wire non-load bearing joint described in this embodiment, said method is realized based on a telescopic wire non-load bearing joint connection device, said one The sleeve-type wire non-load-bearing joint connection device includes a double-hole main pipe 4 and two sleeve wedge-shaped fasteners,

[0021] Each inserting wedge fastener includes through-hole wedge inserting device 1, flat washer 2 and nut 3,

[0022] One end of the through-hole wedge inserter is a wedge-shaped structure, and four cross grooves are evenly distributed on the four sides of the wedge-shaped structure. The circle has the same hole diameter as the threaded structure,

[0023] The flat washer 2 and the nut 3 are both set on the threaded structure of the through-hole wedge inserter 1, and the flat washer is placed on the inner side of the nut,

[0024] Two nes...

specific Embodiment approach 2

[0030] Specific embodiment 2: This embodiment is a further description of a kind of sleeve-type wire non-load-bearing joint connection method described in specific embodiment 1. In this embodiment, the diameter of the inner hole of the double-hole main pipe is larger than that of the wedge-shaped fastener 1, and is smaller than the outer diameter of the wedge-shaped structure of the wedge-shaped fastener 1.

Embodiment

[0032] A method for connecting non-load-bearing joints of sleeved wires, said method is realized by the following steps:

[0033] Step 1. Make two wedge-shaped fasteners 1 with a wedge-shaped structure at one end and a threaded structure at the other end. The diameter of the wedge-shaped outer circle of the wedge-shaped fastener is 34MM. The width is 6MM, the inner diameter of the through hole of the inserted wedge fastener is 20MM, and the diameter of the external thread of the inserted wedge fastener is 16MM.

[0034] Step 2. Insert two wedge-shaped fasteners 1 in opposite directions from the threaded structure into the two-hole main tube 4 with a length, width and height of 70MM*70MM*35MM. The diameters of the two inner holes are both 21MM.

[0035] Step 3. Insert two gaskets 2 with a diameter of 42MM and a thickness of 2MM into the threads of the two wedge fasteners respectively, and then respectively insert two nuts 3 into the threads of the two wedge fasteners 1.

Abstract

The invention discloses an insertion type connection method implemented by non-force-bearing connectors of wires, and relates to the field of connecting hardware fittings of wires. The insertion type connection method includes steps of firstly, sequentially penetrating two wedge-shaped fasteners into two inner holes of a double-hole main pipe from threaded structures in opposite directions; secondly, respectively penetrating two plain washers into threaded positions of the two wedge-shaped fasteners, and further respectively penetrating two nuts into the threaded positions of the two wedge-shaped fasteners; fourthly, penetrating the wires into the wedge-shaped fasteners, fastening the nuts and the plain washers at the double-hole main pipe by the aid of wrenches and fixing the wires. The insertion type connection method has the advantages that problems of complexity in connection, low work efficiency and poor power supply reliability of existing wire connection modes can be solved by the aid of the insertion type connection method, and the wires can be fixed by the aid of the insertion type connection method.

Description

technical field [0001] The invention relates to a sleeve-in type wire non-load bearing joint connection device. It belongs to the field of wire connecting fittings. Background technique [0002] The sleeve-type wire non-load-bearing joint connection device is one of the indispensable fittings for the non-load-bearing connection of power system transmission and distribution line wires. In actual work, parallel groove clamps are generally used for installation and connection. The reliability of the connection is not strong. After the bolts are loose, the wires will fall into the air or be placed on the cross arm, causing the line grounding fault; the device is fastened by wedge After being tightened with a wrench, the contact is tight and there is no loosening of the wire. It is a new type of fitting for installing and connecting the non-load-bearing joint of the wire. It has the characteristics of improving work efficiency, ensuring the reliability of power supply, and conn...
