Cable intermediate head connecting device

Abstract

The invention relates to the technical field of cable intermediate head connecting devices, and particularly discloses a cable intermediate head connecting device. The device is used for connecting end cells of two cables and comprises an outer connecting pipe, an inner connecting pipe a, an inner connecting pipe b and a plurality of bolts. Firstly, end battery cells of two cables are inserted into the inner connecting pipe a and the inner connecting pipe b respectively, then the inner connecting pipe a and the inner connecting pipe b are inserted into the outer connecting pipe from the two ends of the outer connecting pipe respectively, and finally the inner connecting pipe a and the inner connecting pipe b abut against the inner connecting pipe a and the inner connecting pipe b through bolts respectively, so that the inner connecting pipe a and the inner connecting pipe b can be fixed into the outer connecting pipe respectively. When the device abuts against the inner connecting pipe a and the inner connecting pipe b in the outer connecting pipe through a plurality of bolts, no burrs occur, and the service life of the cable intermediate head is not affected.

Description

technical field [0001] The invention relates to the technical field of cable intermediate head connection devices, in particular to a cable intermediate head connection device. Background technique [0002] With the development of the power industry, a large number of 10kV distribution network lines use cables to replace the original overhead lines. The advantages are high power supply reliability, good power supply security, and low operation failure rate. The service life largely depends on the production process level of the cable head and the middle head of the cable. At present, most of the crimping process of the wire core of the middle head of the cable uses a hydraulic copper connecting tube to crimp the two wire cores together. The crimping causes There are burrs on the surface of the copper tube. If the burr is not handled properly, the surface of the copper tube will be polished smooth, and a sharp discharge will occur on the copper tube, which will endanger the s...
