Description

Ground wire ground terminal installer

technical field

The utility model relates to grounding related equipment, in particular to a grounding wire ground terminal installer.

Background technique

As we all know, the substation is equipped with a large number of AC electrical equipment for power transformation, power transmission and distribution, and other electrical equipment. In order to ensure the normal operation and safety protection of these electrical equipment, these electrical equipment must be grounded safely and reliably. Currently, the commonly used The grounding wire ground end installer (as shown in Figure 1) includes a fixed part connected to the equipment to be grounded. The fixed part has an external thread and a lock hole. The grounding copper nose is fixed on the fixed part by a fastening nut, and then passed through The lock locks the keyhole. Because of the needs of work, such as measuring ground resistance, etc., this ground wire ground terminal installer needs to be disassembled frequently. When disassembling, you need to open the lock, unscrew the fastening nut, take out the copper nose, and then When installing, it is necessary to put on the copper nose, screw in the nut, and lock the lock. Such operations are too many, and the fastening nut is easily rusted after being exposed to wind and rain, making it impossible to disassemble.

Utility model content

In view of the above-mentioned problems existing in the ground wire ground end installer in the prior art, the utility model provides a ground wire ground end installer with less disassembly and assembly procedures, convenient operation, and fast clamping.

The technical solution adopted for the problem to be solved by the utility model is: the grounding wire ground end installer includes a fixing part and a clamping part, and a bump is arranged on the fixing part, and the cross section of the bump is octagonal , one end of the fixing part is fixed on the equipment to be grounded, the other end of the fixing part is provided with a lock hole, the clamping part includes a clamping cavity, the lock can pass through the clamping cavity to lock the lock hole, the clamping cavity The front part is provided with a plurality of claws at annular intervals, the claws are provided with clamping springs, the outer wall of the clamping chamber is provided with stretching springs, and the rear of the clamping chamber is connected with a copper nose and a grounding wire.

The advantages of the utility model are: 1. When disassembling the ground end of the grounding wire, the process of disassembling the fastening nut can be omitted, which can prevent the fastening nut from rusting and make it difficult to disassemble; 2. Adopt claws and bumps The clamping method between them, combined with the clamping spring and the stretching spring, makes the fastening performance good, and the operation is convenient and fast.

Detailed ways

In order to enable those skilled in the art to better understand the technical solution of the utility model, the utility model will be further described in detail below in combination with specific embodiments according to the accompanying drawings.

As shown in Figures 2 and 3, the ground wire ground end installer includes a fixing part 11 and a clamping part 3, the cross section of the clamping part matches the shape of the fixing part, and a bump 9 is arranged on the fixing part , the cross-section of the bump is octagonal, one end of the fixed part is fixed on the equipment 12 to be grounded, the other end of the fixed part is provided with a lock hole 5, the clamping part includes a clamping cavity 10, and the lock 8 can be Through the clamping cavity to lock the lock hole, the front part of the clamping cavity is provided with several claws 1 at annular intervals. The claws are made of an alloy material with good conductivity and elasticity. In order to quickly clamp the bump, grab the The outer inclined surface of the outer inclined surface of the protrusion is preferably matched with the outer inclined surface of the bump. The clamping spring 2 is arranged on the claw to ensure a certain clamping force when clamping. The outer wall of the clamping cavity is provided with a stretching spring 4. The function is that the clamping part maintains a certain degree of elasticity when it is inserted into the fixed part and taken out. The elastic force of the stretching spring should be greater than that of the clamping spring. The rear part of the clamping cavity passes through the gasket and the bolt (not shown in the figure) Copper nose 7 and ground wire 6 are connected.

When the utility model is in use, insert the clamping cavity of the clamping part into the fixed part, and force forward. Since the outer slope shape of the front-end claw matches the outer slope of the bump, the claw can quickly land on the slope of the bump. Move, and finally tighten the clamping projection under the clamping of the clamping spring. Similarly, when disassembling, the lock is released, and the clamping part can be easily taken out only by applying a little external force. The working efficiency is higher than that of the original The mounter has been greatly improved.

The above embodiments are only used to illustrate the technical solution of the utility model without limitation. Although the utility model has been described in detail with reference to specific embodiments, those skilled in the art should understand that the technical solution of the utility model can be modified or equivalent Replacement, without departing from the spirit and scope of the technical solutions of the present utility model, should be covered by the scope of protection of the claims of the present utility model.
