Problems solved by technology

[0002] At present, in the installation and use of power grid distribution lines, the connection and fastening of wires and cross-arm type, bobbin type and column type insulators are all connected and fastened by copper wires, aluminum wires or other metal wires. The technology and method not only bring troubles to the construction, but also waste wire materials, and the use effect is very poor and extremely unsightly, and the anti-theft performance is not strong

Embodiment 1

[0020] As shown in Figures 1 to 5, a fastening device for connecting power grid line insulators and wires, the connecting fastening device includes a housing 10 and a cassette 20 for connecting and fastening the housing, the housing 10 is made of high compressive strength And bendable elastic material is made, and the shape of its end face is U-shaped substantially, and wire 30 and insulator 40 are all located in housing 10, and the upper part of housing 10 has the inner circular arc that matches with the outer edge surface of wire 30 Surface wire groove, the shell 10 is placed on the wire 30 through the inner arc surface wire groove, and a hoop 11 for wrapping the insulator 40 is extended downward on the four groove sides of the two ends of the wire groove. The hoop is integrated with the edge of the slot; the hoop 11 has an inner arc surface that matches the outer edge of the insulator 40, and the hoop 11 clamps the insulator 40 through the inner arc surface, and the two hoop...

Embodiment 2

[0024] As shown in Figures 6 and 7, the difference from the first embodiment is that each hoop 11 has a through opening 14, and the openings 14 on the four hoops are symmetrically distributed, and the cable ties 50 are passed through the hoops. Symmetrically distributed openings on the hoop. This structure is suitable for the contact installation of the wire 30 and the insulator 40 in a T-shaped cross. During installation, vertically clamp the wire slot on the arc surface of the housing 10 on the wire 30, and at the same time be stuck between the wire slots of the insulator 40, and then use a cable tie 50 to pass through the four symmetrically distributed wires on the four hoops 11. A through hole 14 binds the wire 30 and the insulator 40 tightly. In order to tie tighter, also can offer more than two openings 14 on every hoop, like this as required, on the four openings of every group of symmetrical distribution, wear tie.

Embodiment 3

[0026] As shown in FIG. 8 , the housing 10 of this embodiment is made into an elbow shape, which is applicable to the bend of the wire 30 , and its installation and use methods are the same as those of the first embodiment.

[0027] In order to facilitate installation, bayonets and fastening parts can be provided at the ends of the hoops, and openings are opened in the middle of each hoop, so that the same part can be suitable for the installation needs of the above-mentioned wires and insulators in different forms.

Abstract

The invention discloses a fastener for connection of a power line insulator and a wire, and is characterized in that the fastener comprises a housing, and a fastening regulating structure for fastening the wire and the insulator, wherein a wire casing for the wire to pass through is arranged at the upper part of the housing, an anchor ear for wrapping the insulator is respectively downwardly extending from the four casing edges at two ends of the wire casing, and the anchor ears are integrated with the chase edges; and the fastening regulating structure is arranged on the anchor ears. The inventive connection fastener can regulate and fasten the connection of the insulator and the wire in accordance with the size thereof, and can keep the connection of the insulator and the wire when the wire turns at the angles. The invention has the advantages of convenient installation, esthetic appearance, good economical and practical value, firmness, good durability, and theft protection.

Description

technical field [0001] The invention relates to a fastening device for connecting insulators and wires of electric network lines, in particular to a fastening device for connecting cross-arm type, bobbin type and column type insulators and wires of electric network lines. Background technique [0002] At present, in the installation and use of power grid distribution lines, the connection and fastening of wires and cross-arm type, bobbin type and column type insulators are all connected and fastened by copper wires, aluminum wires or other metal wires. The technology and method not only bring troubles to the construction, but also waste wire materials, and the use effect is very poor and extremely unattractive, and the anti-theft property is not strong. Contents of the invention [0003] The object of the present invention is to provide an adjustable fastening device for the connection between the grid line insulator and the conductor. [0004] Above-mentioned purpose of ...
