Problems solved by technology

[0004] There are many problems in the actual installation of the grounding wire. For example, the elastic coefficient of the tension spring of the existing grounding wire clip is relatively large, and it takes a lot of force to stretch the grounding wire operating rod to a certain opening, which limits the gender of the operator; The clip blocks the operator's sight during the installation process, and it is not easy to install it in place at one time, which increases the difficulty of installation; during the installation process of the existing ground wire clip, it is necessary to move the operating lever back and forth and up and down to find the best installation position, which increases the The physical energy consumption of the operator increases the operational risk, etc.

Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings.

[0025] like figure 1 and figure 2 As shown, the bite-type grounding clamp is composed of four parts: clamping device 100, linkage device 200, booster spring 400, and bracket 300. Except for booster spring 400, other parts are made of aluminum with low density and high conductivity. The booster spring 400 is arranged in the bracket 300 , the linkage device 200 passes through the booster spring 400 and is fixed by the bracket 300 , and controls the clamping device 100 to engage.

[0026] like image 3 As shown, the clamping device 100 is composed of three parts, which are respectively the connecting shaft 103, the wire clamp ring 101 and the linkage buckle 104, and one end of the two arc-shaped wire clamp rings 101 is connected with the connecting shaft 103, so that the constituted The diameter of the wire clamp ring 101 is large enough to completely clamp the wire, ...

Abstract

The invention discloses an engaging-type ground wire clamp, which consists of a clamping device, a linkage device, a support and a power-assisted spring. The power-assisted spring is disposed in the support. The linkage device passes through the power-assisted spring, is fixed by means of the support, and controls engaging of the clamping device. A ground wire adopting the wire clamp is time-saving and labor-saving to install. Therefore, the visual field of an operator is broadened, the success rate of installation of a ground wire at one time is increased, the contact area of the ground wire clamp and a lead is increased, operation risks are minimized, and the operation efficiency is improved.

Description

technical field [0001] The invention relates to an accessory structure of a maintenance tool for electric equipment, in particular to a snap-fit ​​grounding clamp. Background technique [0002] In the power system work, the staff must strictly implement the "Electricity Safety Work Regulations" in their work. The "Electrical Safety Work Regulations" stipulates that technical measures must be taken to ensure safety for electrical equipment and lines that need to be repaired after power outages. The technical measures to ensure safety mainly include: power failure, power inspection, grounding, hanging signs and installing barriers. [0003] Grounding is mainly achieved by installing grounding wires. As an important part of switching operations, the installation of grounding wires is often performed by substation operation and maintenance personnel, especially in the process of comprehensive automation transformation and equipment overhaul. [0004] There are many problems in...
