Cable splicing connecting box

Abstract

The invention discloses a cable splicing connecting box, which belongs to a cable line construction and maintenance technology field, and is mainly used for cable splicing connection. The cable splicing connecting box comprises an upper box body, a potting opening, a potting opening cover plate, an upper C-shaped sealing gasket, a sealing strip, a protection cover, a cable core wire connector, a lower C-shaped sealing gasket, a lower box body, a fastening bolt, and liquid gel. The cable splicing connecting box is mainly used for solving problems of conventional technical schemes such as complicated technology, easy heating of electrical connecting points, poor insulation and waterproof performance, frequent occurrence of short circuit or open circuit faults. The technical scheme of the cable splicing connecting box is characterized in that 1, terminal sheathes and cable core wire insulation layers of two cables are stripped off, and the in-phase cable core wire conductors of the two cables are oppositely inserted in conductor slots at the same length, and then bolts are tightened, and the in-phase cable wire core conductors are pressed tightly;2, the box is buckled, and the box body is filled with the liquid gel in a potted way, and after a plurality of minutes, the liquid gel is solidified.

Description

technical field [0001] The invention belongs to the technical field of cable line construction and maintenance, and relates to a cable splicing and connecting box. Background technique [0002] In the construction and maintenance of cable lines, it is often necessary to insulate, seal, and waterproof the connection of two sections of cables. The existing technical solutions provide heat-shrinkable or cold-shrinkable cable joints. Practice has proved that these two technical solutions have many shortcomings. First, the construction process is complicated; second, the contact resistance of the electrical connection point is large, and it is easy to generate heat to cause electrical fire accidents; third, the insulation and waterproof performance is poor; fourth, short circuit and open circuit faults occur frequently, especially when the cable is directly buried In particular, short-circuit flash explosion accidents of joints caused by poor insulation and waterproof performance...
