Power cable connecting joint

Abstract

The invention discloses a connector device which can connect slave-master connecting devices through a single-hand suspended operation so as to connect a cable when high-altitude work is performed. The power cable connecting joint is characterized in that one side of a connecting plate is arranged at one end of a main connecting sleeve, the inner wall of the main connecting sleeve is provided witha plurality of conical bulges, the main connecting sleeve is made of copper, the internal part of the connecting plate is provided with a strip-shaped slot, one side of a supporting plate is arrangedat the other side of the connecting plate, the supporting plate is provided with two through holes which are close to the other side of the supporting plate, one side of a limiting plate is arrangedat the other side of the connecting plate, the limiting plate is located above the supporting plate, the limiting plate is provided with two through holes which respectively correspond to the two through holes in the supporting plate, the limiting plate is provided with a square groove, a pressing plate is arranged in the square groove and is hinged with the limiting plate, a limiting bulge is arranged on the pressing plate and faces towards the supporting plate, the limiting bulge is hemispherical, and two clamping plates are located between the limiting plate and the supporting plate and arerespectively located at two sides of the pressing plate.

Description

technical field [0001] The invention relates to a power cable connecting joint, relates to a connecting head device used in power construction for connecting power cables, and belongs to the field of power construction. In particular, it relates to a connector device capable of connecting two sub-mother connecting devices and further connecting cables through a one-hand suspension operation during high-altitude operations. Background technique [0002] At present, in electrical construction operations, when connecting and continuing the cable end, the wire lug is usually used as the connecting device. When in use, the wire lug is connected to the position of the stripped cable end to be pressed and fixed, and then the two fixed The cable lug is fixed and connected by bolts. The cable connection operation is usually carried out at high altitude. When tightening the bolts, two wrenches are required, one for fixing the bolt and the other for tightening the nut. Tightening of t...

Problems solved by technology

[0002] At present, in electric power construction operations, when connecting and continuing the cable ends, wire lugs are usually used as connection devices. The wire lug is fixedly connected by bolts. The cable connection operation is usually carried out at high altitude. When tightening the bolts, two wrenches are required, one is used to fix the bolts and the other is used to tighten the nuts. The fastening of bolts has certain dangers for hands detached from the support surface for high-altitude operations. In order to ensure the fastness of the connection, the bolts are usually tightened very tightly, which requires a certain strength for the muscles of the arms of the workers. Long-term work will make the The operator's arm is sore, and the wrench is not firmly held and may fall, which poses a threat to the safety of the ground operator, and the use effect is not good
