The invention belongs to the technical field of overhead line wire connecting devices, and discloses an electric power connecting fitting which comprises a first fitting piece, a second fitting pieceand a connecting piece. The connecting piece is arranged at one end of one of the first fitting piece and the second fitting piece, and a first semicircular groove is formed in the first fitting piecein the length direction. A plurality of semicircular grooves are formed in the groove bottom of the first semicircular groove, a second semicircular groove is formed in the length direction of the second fitting piece, a plurality of semi-convex rings are arranged at the groove bottom of the second semicircular groove, the semi-convex rings and the semicircular grooves are arranged in a one-to-one correspondence mode, and the first fitting piece and the second fitting piece are in an attached state. The side, provided with the first semicircular groove, of the first fitting piece is attachedto the side, provided with the second semicircular groove, of the second fitting piece, and the first fitting piece and the second fitting piece clamp a high-voltage cable connector in a circular groove defined by the first semicircular groove and the second semicircular groove. The power connection fitting can stably clamp the high-voltage cable connector, and the power supply stability of a high-voltage cable is ensured.
Description
technical field [0001] The invention relates to the technical field of connection devices for overhead wires, in particular to a power connection fitting. Background technique [0002] The overhead line of the transmission line needs to be connected with connecting fittings. The overhead line is usually a high-voltage cable. The components of the high-voltage cable from the inside to the outside include: conductor, inner insulator, inner sheath, filler and outer insulator. It is an important part of the installation of overhead conductors to withstand large tension, and the installation effect affects the power supply efficiency of the line. [0003] The existing connecting fittings are complex in structure, usually need to use hydraulic pliers to crimp and fix the connecting fittings, the operation is cumbersome, when the connecting fittings need to be replaced, hydraulic pliers are also required to operate the connecting fittings, otherwise the wires and connecting fitting...
