Power fittings are metal accessories that connect and combine various devices in the power system to transmit mechanical loads, electrical loads, and a certain protective effect. Puncture-type power fittings can take electricity from the wire and pierce the insulator protective layer of the wire. It has good contact with the conductor, so as to draw out the electric energy and introduce part of the current in the main line into the branch line. The existing piercing power fittings may loosen due to the different thickness of the wire when fixing the wire. It is inconvenient to operate with tools, and it is difficult to remove after fixing, which is not conducive to subsequent maintenance operations.

The puncture-type power fitting includes a left and right adjacent puncture system. The puncture system includes a housing. The middle of the upper side wall of the housing is provided with an adjusting head up and down. The inside of the adjusting head is provided with an adjusting rod, and the lower end of the adjusting rod is provided with a puncture needle. The upper and lower sides of the outer side wall of the adjusting rod are respectively provided with limit rings. The inside of the housing and between the upper and lower limit rings are provided with a fixing seat. The inside of the fixing seat is provided with an adjusting nut, which is threadedly connected with the adjusting rod. , The middle of the lower side wall of the housing is provided with a clamping groove, the lower side wall of the housing is provided with a piercing hole through the upper side of the clamping groove, and the upper surface of the inner cavity of the housing is provided with a reset seat in left-right symmetry , The left and right ends of the upper side wall of the housing are respectively provided with reset through holes up and down, and the reset head is slidably connected inside the reset through hole. A reset spring is provided between the adjacent reset head and the reset seat. The lower end of the reset head is provided with a reset There is a reset rack, the left and right ends of the lower side wall of the housing are respectively provided with fixing through holes up and down, the lower end of the housing is provided with a clamping seat, and the middle of the upper surface of the clamping seat is provided with two clamping grooves. The left and right ends of the upper surface of the seat are respectively provided with fixed racks for use with the reset racks, the fixed racks pass through the fixing through holes, and the left and right corresponding adjusting nuts are provided with wires that pass through the fixed seat and the housing .

Compared with the prior art, the present invention has the beneficial effects that the puncture-type power fittings respectively fix the main line with current flowing and the branch line that needs to be introduced through two puncture systems, and drive the puncture needle to move up and down through two puncture systems. The branch line is pierced, and the puncture needle is inserted into the external wire. There is no need to remove the insulation protection layer of the wire in advance, puncture the conductor part of the wire, and shunt the current in the main line into the branch line for electricity. The fixed rack and the reset rack fix the clamping base on the shell, so that the clamping base can only be pushed upwards, but cannot be pulled out, which ensures the clamping degree of the external wires and avoids the loosening of the external wires. , The distance between the clamping base and the housing can be adjusted at will, so that the device can clamp wires of different diameters. When the device needs to be removed from the wire, push the reset head to the inside to make the reset rack no longer The fixed rack is clamped, and then the clamping base can be removed, and the return spring is used for resetting. The upper surface of the inner cavity of the housing is provided with reset seats symmetrically, and the left and right ends of the upper side wall of the housing are respectively provided with reset through holes, which can clamp wires of different diameters, and the clamping wires are not loose and easy to remove.
