Problems solved by technology

[0002] Because the traditional steel-cored aluminum conductor is greatly affected by temperature during power transmission, it is prone to sag, which seriously affects the transmission capacity of the power grid. , light weight, less transmission loss, corrosion resistance and other advantages solve various technical bottlenecks in the field of overhead transmission, and become the development trend of overhead conductors in the future, but there is currently a lack of matching special clamps in the market. During the construction, the carbon fiber core and the outer aluminum wire often slide away, resulting in loose strands of the wire

Embodiment Construction

[0015] Such as figure 1 Shown: a pressure-resistant clamp dedicated to carbon fiber wires, including an outer sleeve 2 and an inner member, the inner member includes a compression tube 3 with a groove at one end, a compression tube 6 with grooves at both ends, and a The end pipe 7 of the groove, the compression pipe 6 with grooves at both ends is threadedly connected with the compression pipe 3 and the end pipe 7 with grooves at one end respectively, and the grooves are provided with frustum cavity The structural member 4, the shuttle-shaped collet 5 is arranged in the cavity of the frustum body.

[0016] As a preferred solution of the present invention, both the structural member 4 and the shuttle-shaped collet 5 are made of hard aluminum-magnesium alloy.

[0017] As a further preferred solution of the present invention, the front end of the compression tube 3 with a groove at one end is a compressible deformation zone.

[0018] As a further preferred solution of the prese...

Abstract

The invention discloses a special pressure-resistant wire clamp for carbon fiber wires, which includes an outer sleeve and an inner piece. The inner piece includes a compression tube with a groove at one end, a compression tube with grooves at both ends and a compression tube with a groove The end pipes, the compression pipes with grooves at both ends are respectively screwed with the compression pipes with grooves at one end and the end pipe, and the grooves are equipped with structural parts with frustum cavity inside. A shuttle-shaped elastic collet is arranged in the cavity of the frustum body. The present invention fully fastens the inside and outside of the carbon fiber wire by adopting a double fastening mechanism, which effectively avoids the occurrence of slippage between the inner core and the outer layer, and adopts an organic compression tube structure to further improve the tightness of the wire clamp. Solid reliability, simple structure, easy operation, safe, stable and reliable.

Description

technical field [0001] The invention relates to the technical field of electric carbon fiber wire construction equipment, in particular to a pressure-resistant clamp specially used for carbon fiber wires. Background technique [0002] Because the traditional steel-cored aluminum conductor is greatly affected by temperature during power transmission, it is prone to sag, which seriously affects the transmission capacity of the power grid. , light weight, less transmission loss, corrosion resistance and other advantages solve various technical bottlenecks in the field of overhead transmission, and become the development trend of overhead conductors in the future, but there is currently a lack of matching special clamps in the market. During the construction, the carbon fiber core and the outer aluminum wire often slide, resulting in loose strands of the wire. Contents of the invention [0003] The object of the present invention is to provide a special voltage-resistant clam...
