The invention discloses a novel
power cable connecting device. The device comprises a connecting
pipe, a connector is mounted at the right end in the connecting
pipe; a socket ring is fixedly installed on the right side of the connector, a plurality of annularly-distributed contact pins located in the socket ring are fixedly installed on the right side of the connector, a conductive elastic piecelocated in the connecting
pipe is fixedly installed on the left side of the connector, an installation ring is arranged at the left end of the inner side of the connecting pipe, and a conductive wireis arranged on the inner side of the installation ring. According to the invention, the triangular pyramids play a role in
cutting and stripping wires and cables and also play a role in fixed-size
cutting; the vertical surface of the triangular
pyramid is matched with the vertical surface of the triangular
pyramid-shaped groove; the conductive wire can be effectively prevented from slipping from the connecting device, accidents such as
fire disasters are prevented, the mounting process of the device is also simple, the conductive wire can be fixed and prevented from slipping only by insertingthe conductive wire from the left side of the connecting pipe, and subsequent maintenance of the conductive wire and the device is facilitated for workers.
