Description

Technical Field

[0001] The utility model relates to the technical field of insulating wire clamps, in particular to an insulating wire clamp for aerial work. Background Art

[0002] Insulated wire clamps are small parts used to connect lines. They can hook the wires during the connection process and ensure that the lines are not damaged. At the same time, because they have insulation, they can effectively prevent short circuits. This type of wire clamp is widely used in the connection of circuits, control lines, and signal transmission lines, showing many advantages such as simple installation and reliable contact.

[0003] The existing insulated wire clamps are mostly installed by sleeved the upper and lower shells of the wire clamp on the outside of the cable, and then the torque nut on the wire clamp is tightened with a socket wrench. During the process, the contact blade will pierce the cable insulation layer and contact the conductor. It has the advantages of simple structure, convenient installation, constant puncture pressure without wire stripping, etc. However, when it is applied to high-altitude operations, there are some disadvantages. For example, the existing wire clamp shell is not stable enough when fixed. During use, the wire clamp may loosen and fall off due to factors such as wind and vibration, thereby affecting its use. In order to solve the above problems, while facilitating its quick installation, the connection between the insulated wire clamp and the cable is strengthened to avoid its falling off due to factors such as wind or vibration and affecting its use. For this reason, we propose an insulated wire clamp for high-altitude operations. Utility Model Content

Compared with a smooth shell, the multi-faceted design can better resist external pressure, vibration and impact, reduce the possibility of deformation and damage, and ensure the stability and reliability of the insulating wire clamp in high-altitude operations or other harsh environments. The shell surface with a multi-faceted structure has a larger heat dissipation area. When working under high load, a certain amount of heat may be generated inside the wire clamp. The multi-faceted design helps to increase the heat dissipation area, promote heat dissipation, reduce the working temperature of the wire clamp, improve the reliability of long-term use, and is more practical.

After placement, the nut 5 can be turned by a wrench, and the upper shell 1 and the lower shell 2 are squeezed close to each other through the threaded connection between the nut 5 and the insulating layer 6, so as to clamp the cable. After being pressed down to a certain depth, the puncture knife 14 will accurately pierce the cable to achieve electrical connection, reducing the problems of poor contact or unstable connection that may exist in traditional connection methods. When the upper shell 1 is pressed down, the blocks 13 on both sides of the bottom of the plug 10 will be retracted into the retraction groove 12 under the pressure of the slot 11, and the block 13 will be ejected by the spring after passing through the slot 11, so as to perform clamping, fixing and limiting, which is simpler to connect and fix the two sets of connection shells 8, and through the adsorption connection between the magnet 17 and the adsorption groove 18, the entire cable is The clamp structure is more compact and not easy to loosen. By setting the arc groove 9 between the two groups of connecting shells 8, the cables outside the connection are limited and fixed, so that the wire clamp can form a tighter combination when fixing the cable, preventing the cable from slipping or shifting during work, and by setting the multi-faceted structure of the outer wall of the upper shell 1, the structural strength and stability of the shell can be increased. In high-altitude operations or other harsh environments, the stability and reliability of the insulating wire clamp can be ensured, and the multi-faceted shell surface has a larger heat dissipation area. When working under high load, a certain amount of heat may be generated inside the wire clamp. The multi-faceted design helps to increase the heat dissipation area, promote heat dissipation, reduce the working temperature of the wire clamp, and improve the reliability of long-term use. Through the mutual cooperation between the above-mentioned structures, the device facilitates the quick installation of the wire clamp while effectively strengthening the connection between the insulating wire clamp and the cable, avoiding its falling off due to factors such as wind or vibration, which affects its use, and is more convenient and practical.
