Problems solved by technology
The tension towers on the line need to have multiple connecting wires for connecting fittings. If the connecting fittings are not tightly connected and there is a gap between the fittings, the current will be conducted in the gap between the fittings (the conductor is air at this time), resulting in Excessive heat, causing wire splices to overheat
[0003] If the method of power outage maintenance is adopted, it will have a great impact on the construction of electric customers and reduce the reliability of equipment power supply

The invention discloses a splicing fitting clamping device, and belongs to the technical field of live-line work tools and instruments. The splicing fitting clamping device includes an insulating bar and a clamping mechanism, wherein the insulating bar is movably connected with the clamping mechanism; the clamping mechanism includes an E-shaped framework and split press blocks in the frame work; the split press blocks are in cuboid structure; a gap being greater than the thickness of the splicing fitting is formed between the split press blocks and the inner wall of the framework in the up and down direction; the split press blocks include a first press block and a second press block; the press block and the second press block contact each other through an inclined plane; the first press block is connected with the framework in the up and down direction in a sliding manner; the front and back surfaces of the frame work are each provided with a baffle plate which is used for stopping the split press blocks moving back and forth; the insulating bar pushes the second press block to move left and right; and the second press block drives the first press block to move upwards to clamping the splicing fitting. The splicing fitting clamping device can fasten the splicing fitting in a live line situation, is simple in structure, and is easy and simple to operate.
Description
technical field [0001] The invention belongs to the technical field of live working tools, and in particular relates to a clamping device for connecting metal tools. Background technique [0002] Splicing fittings are fittings used for the connection between two wires and can meet the mechanical and electrical performance requirements of the wires. The tension towers on the line need to have multiple connecting wires for connecting fittings. If the connecting fittings are not tightly connected and there is a gap between the fittings, the current will be conducted in the gap between the fittings (the conductor is air at this time), resulting in Excessive heat, causing overheating of the wire connectors. [0003] If the method of power outage maintenance is adopted, it will have a great impact on the construction of electric customers and reduce the reliability of equipment power supply. So there is an urgent need for a tool or device that can fasten the connecting fittings ...
