Cable terminal tightening device

Abstract

The invention discloses a cable terminal tightening device. The cable terminal tightening device comprises a tightening device and a tightening wire clip, wherein the tightening device comprises a wire pressing body, a movable press block and a pressing screw rod; the wire pressing body comprises a connecting part and a support part; the movable press block is arranged between the connecting part and the support part through the pressing screw rod and is only performed with the linear movement between the connecting part and the support part; the tightening wire clip comprises a male clip, a female clip and a locking device; the male clip and the female clip are tightly matched with the movable press block and the support part; in the use process, a bent cable terminal is arranged between the male clip and the female clip, and then the pressing screw rod is rotated to enable the movable press block to move relative to the support part until the cable is pressed under the matching action of the male clip and the female clip; the male clip, the cable and the female clip are locked together through the locking device; finally, the pressing rod is reversely rotated to disengage the tightening wire clip from the tightening device. The cable terminal tightening device has the advantages that the cable terminal can be quickly tightened, the fixing efficiency of the cable terminal is greatly improved, the firmness is good, the structure is simple, and the universality is good.

Description

technical field [0001] The invention relates to the field of power tools, in particular to a cable terminal fastening device. Background technique [0002] It is very important to ensure the safe and stable operation of the power grid in today's society. The cable is erected on the pole or building through the street code. The cable end is generally fixed by bending the cable end around the terminal street code and then In the tensioned state, use metal wires or other fixing devices to bind or fix the cable ends; at present, construction workers usually use traditional methods such as manpower or simple tools to bend the cable ends and make the cable ends in a tensioned state The cable ends are bound and fixed with metal wires. Due to the thicker diameter of the cables with large currents, it is difficult to use the traditional metal wire binding method to operate, and there is no uniform standard for the binding method, which is very random, resulting in cable ends. The fi...

The cable end is generally fixed by bending the cable end around the terminal street code and then In the tensioned state, use metal wires or other fixing devices to bind or fix the cable ends; at present, construction workers usually use traditional methods such as manpower or simple tools to bend the cable ends and make the cable ends in a tensioned state The cable ends are bound and fixed with metal wires. Due to the thicker diameter of the cables with large currents, it is difficult to use the traditional metal wire binding method to operate, and there is no uniform standard for the binding method, which is very random, resulting in cable ends. The firmness of the binding is difficult to guarantee, and the cable end is easy to loosen and fall off the street yard, which brings safety hazards
