A loose-proof connecting cable clamp

A technology for connecting cables and cable clamps, which is applied in the direction of connection, conductive connection, and electrical component connection. It can solve problems such as easy loosening of bolt connections, failure of connecting cable clamps to work normally, and poor handling of wire connections, so as to avoid maintenance.

Problems solved by technology

[0002] In today's society, it is very important to use electricity safely and ensure the safe and stable operation of the power grid. The poor connection of wires has brought a lot of trouble to people, and even has potential safety hazards.
The bolt connection of the existing cable clamp used to clamp the bare wire of the cable will loosen after a long time, especially in the environment with a lot of grease or high-frequency vibration, the bolt connection is more likely to loosen, which will cause the cable clamp to clamp The bare wire holding the cable is unstable or even loose, causing the corresponding connecting cable clamp to fail to work normally

Embodiment 1

[0023] like Figure 1-2 As shown, a kind of anti-loose connection cable clamp includes two cable clamps made of conductive metal, which are respectively the first cable clamp 21 and the second cable clamp 22, the first cable clamp 21 and the second cable clamp The two cable clamps 22 respectively include a first clamp body and a second clamp body, each of which is provided with two anti-loosening bolt assemblies 1 .

[0024] Wherein, the anti-loosening bolt assembly 1 includes a bolt 11 and an anti-slip pressure plate 12, the back of the anti-slip pressure plate 12 is rotatably connected to the front end of the bolt 11, and the surfaces of the bolt 11 and the anti-slip pressure plate 12 are respectively provided with relative first stops. The anti-reverse helical gear and the second anti-reverse helical gear, the first anti-reverse helical gear and the second anti-reverse helical gear are respectively composed of a plurality of first anti-reverse helical teeth 111 and a plural...

Embodiment 2

[0032] On the basis of the technical solution of embodiment 1, the anti-slip structure of the anti-slip pressure plate is improved in another way:

[0033] like Figure 4 As shown, the anti-skid structure is a straight groove structure 123 arranged on the top pressure part. The straight groove structure 123 is a concave arc straight groove, so that the surface of the bare cable wire can be embedded in it, and the top pressure part is snapped through the straight groove structure 123 The outer surface of the bare wire of the cable being pressed can limit the rotation of the anti-slip pressing plate 12 relative to the bare wire of the cable.

Abstract

The present invention relate to the field of power tools, in particular to a loose-proof connecting cable clamp which comprises at least two fixedly connected cable clamps, each cable clamp includes aclamp body and an anti-loosening bolt assembly, each anti-loosening bolt assembly includes a bolt and an anti-skid pressing plate, the surface of the bolt in contact with the anti-skid pressing plateis respectively provided with a first check helical tooth and a second check helical tooth, the top pressure part of the anti-skid pressing plate is provided with an anti-skid structure, the wire clamp body is provided with a static clamp head and a threaded hole which are arranged opposite to each other, the bolt is threaded with the threaded hole and faces the static clamp head so as to be ableto cooperate with the static clamp head to clamp the bare wire, and the cable bare wire clamped in each cable clamp can be electrically connected through the cable clamp. The anti-skid structure restricts the rotation of the anti-skid pressing plates relative to the cable, and the engagement of the second anti-skid helical tooth and the first anti-skid helical tooth prevents the bolt from rotating opposite to the anti-skid pressing plate, thereby ensuring that the bolt is not loosened.

Description

technical field [0001] The invention relates to the field of power tools, in particular to an anti-loose connection cable clamp. Background technique [0002] In today's society, it is very important to use electricity safely and ensure the safe and stable operation of the power grid. The poor handling of wire connections has brought a lot of trouble to people, and even has potential safety hazards. The bolt connection of the existing cable clamp used to clamp the bare wire of the cable will loosen after a long time, especially in the environment with a lot of grease or high-frequency vibration, the bolt connection is more likely to loosen, which will cause the cable clamp to clamp The bare wire of the holding cable is unstable or even loose, causing the corresponding connecting cable clamp to fail to work normally. Contents of the invention [0003] In order to solve the above problems, the task of the present invention is to provide an anti-loose connection cable clamp....
