Description

Technical Field

[0001] This utility model relates to the field of parallel groove wire clamp technology, and in particular to a torque-saving parallel groove wire clamp. Background Technology

[0002] Torque-powered parallel groove clamps are non-load-bearing connecting hardware primarily used in power transmission, substation, and distribution line systems for conductor splicing and jumper connections. Their design features include no voltage level limitation, reusability, highly corrosion-resistant aluminum alloy material, span design, and specially designed torque nuts. Parallel groove clamps are used for connecting small-to-medium cross-section aluminum stranded wire or steel-cored aluminum stranded wire, as well as steel stranded wire of overhead lightning protection lines, in non-tensioned positions. They are also used for jumper connections on non-straight towers. These power engineering materials (fittings) are used for connecting conductors to each other, primarily in power line engineering.

[0003] An existing torque-saving grooved wire clamp is prone to problems during actual use. Due to the fixed size of the groove in the clamp seat, it is difficult to flexibly adjust the clamp seat according to the actual cable storage, which affects the overall flexibility of the equipment and the stability of clamping. Utility Model Content

[0006] Through the above technical solution, a clamping groove is provided at the bottom of the first wire clamp, and the limiting clamp is located at the bottom of the clamping groove, which can ensure that the limiting clamp can stably clamp the wire in the clamping groove and provide reliable clamping force.

[0007] As a further improvement to the above scheme, the number of locking screws and locking sleeves is set to two, and the two locking screws and locking sleeves are symmetrically distributed back and forth with the first wire clamp as the center.

[0008] With the above technical solution, a locking sleeve is threadedly connected to the upper surface of the locking screw, and the bottom of the locking sleeve contacts the bottom surface of the first clamp seat. The locking screw can be fixed by the locking sleeve to ensure its stability during use.

[0009] As a further improvement to the above solution, the bottom of the locking sleeve contacts the bottom surface of the first wire clamp seat, the first wire clamp seat is located on top of the second wire clamp seat, and the limiting plate is inserted into the interior of the first wire clamp seat.

[0010] As a further improvement to the above solution, the limiting plate is inserted into the inside of the limiting slot, and the number of the limiting slots is set to two, which are symmetrically distributed on the left and right sides with the first line clamp as the center.

There are two limiting slots, which are symmetrically distributed on the left and right sides with the first wire clamp as the center.

[0016] This invention features a limit spring fixedly connected to the top of a connecting horizontal plate. Two limit springs are fixedly connected to the bottom of the second wire clamp seat and symmetrically distributed around the second wire clamp seat.

The sliding column and the limiting clamp are several in number and symmetrically distributed on the left and right sides with the second wire clamp seat as the center, which can ensure uniform distribution of clamping force and improve clamping stability. The limiting springs are symmetrically distributed on the left and right sides with the second wire clamp seat as the center, which can ensure the stability of the wire clamp in different directions and adapt to various usage scenarios.
