Adjustable confluence clamp

Abstract

The invention discloses an adjustable confluence clamp, which comprises a clamp body (1), a clamp arm (2) and a cable connecting body (3), and is characterized in that the clamp body (1) is connected to the front end of the clamp arm (2); the cable connecting body (3) is coaxially connected with the rear end of the clamp arm (2); the clamp body (1) comprises a front fixed clamp head (11) and a rear movable clamp head (12), the clamp arm (2) comprises a conducting rod (21), and a rotating shaft (22) is arranged in a hollow cavity of the conducting rod (21); the cable connecting body (3) comprises a jack sleeve (31) which coaxially sleeves the rear end part of the conducting rod (21); and the rotating shaft (22) rotates to drive the rear movable clamp head (12) to move back and forth. The adjustable confluence clamp is simple in overall structure and light in weight, and safety and operability are improved.

Description

technical field [0001] The invention belongs to the technical field of uninterrupted operation tools for distribution networks, and in particular relates to an adjustable confluence clamp. Background technique [0002] At present, in the process of overhauling the distribution network without power outage, in order to realize the connection between the low-voltage output end of the mobile box-transformer, the emergency generator car and the generator set and the user end, the old-fashioned cable copper nose on the low-voltage cable and the user-end low-voltage cabinet are all used. The internal busbars are connected by bolts. This connection method takes a long time and has the risk of electric shock to the human body. [0003] With the rapid development of urban construction, the requirements for power supply reliability are getting higher and higher, and the frequency of use of various operation vehicles such as box-conversion vehicles and power generation vehicles has gre...

Problems solved by technology

[0003] With the rapid development of urban construction, the requirements for power supply reliability are getting higher and higher, and the frequency of use of various operating vehicles such as box-type vehicles and generator vehicles has increased greatly. The low-voltage side of box-type vehicles and generator vehicles and the busbar Connecting tool confluence clamps are often used when connecting; CN212908472U discloses an adjustable confluence clamp, which includes a clamp body, a cable crimping body and a sleeve rod, and the rear movable clamp head of the clamp body can be far away from or close to The front fixed clamp head can be adapted to clamp cables of different sizes, and the rear movable clamp head can move back and forth through the push-pull rod located in the sleeve rod; in order to facilitate the operation of the push-pull rod, the tail end of the sleeve rod passes through radially The cable crimping body exposes the tail of the push-pull rod. The axis of the sleeve rod and the axis of the cable crimping body are almost vertically intersected. However, this structure makes the structure of the cable crimping body complex, and the cable crimping body rotates around the sleeve rod. Connection, adding additional contact resistance points, will reduce the current carrying capacity of the system and increase the heat generation under the same current, affecting the stability of the system; while increasing the processing and manufacturing costs, the overall weight is relatively large; and after clamping the copper bar , When inserting the cable plug, it needs to bear a large insertion and withdrawal force. If the cable crimping body is installed vertically, a huge torque will be formed between the clamp body and the clamped equipment copper bar to make the bus bar and supporting copper bar in the cabinet The installed insulating parts bear relatively large stress, and a little carelessness during operation can easily cause damage to the insulating parts supporting the installation of the copper bars. Once the insulating parts are damaged, serious electrical accidents will occur
