Cable terminal for European-style branch box and ring main unit

Abstract

The invention discloses a cable terminal for a European-style branch box and a ring main unit. The cable terminal is connected with a cable sleeve which is fixed on a European-style branch box / a ring main unit in an inserting mode, the cable sleeve comprises a base plate and a bolt arranged on the front of the base plate, the cable terminal comprises a T casing pipe, a cable wiring terminal and an insulation sealing head. The T casing pipe comprises a horizontal casing pipe part and a vertical casing pipe part, wherein the horizontal casing pipe part is communicated with the vertical casing pipe part, the base plate of the cable sleeve is connected with the left side of the horizontal casing pipe part in an inserting mode, the bolt is arranged inside the horizontal casing pipe part, the cable wiring terminal is inserted from a lower end mouth of the vertical casing pipe part and connected with the bolt in a sleeve mode, the insulation sealing head is connected with the right side of the horizontal casing pipe part in an inserting mode and connected with the front end of the bolt in a threaded mode. The cable terminal for the European-style branch box and the ring main unit is simple in structure and convenient to use, facilitates connection between the European-style branch box and the ring main unit and a bypass cable, reduces operation scope, and improves the line power supply reliability.

Description

technical field [0001] The invention relates to a cable terminal used for European-style branch boxes and ring network cabinets. Background technique [0002] When the underground cable between the two branch boxes / ring network cabinets is abnormal and needs to be repaired, after laying the bypass cable on the ground and taking safety protection measures, the bypass cable replaces the underground cable to supply power to the ring network cabinet, so as to achieve no power failure (less power failure) The purpose of maintenance. [0003] At present, the cable casings located in the European-style branch boxes and ring network cabinets mostly use fully insulated, fully enclosed, and fully sealed cable terminals, which cannot be separated from the cables connected to them. [0004] When laying the bypass cable, due to the small space of the European-style branch box and the inlet hole of the ring network cabinet, and the large volume of the cable terminal enclosed with the byp...

Problems solved by technology

[0003] At present, the cable casings located in the European-style branch boxes and ring network cabinets mostly use fully insulated, fully enclosed, and fully sealed cable terminals, which cannot be separated from the cables connected to them.

[0004] When laying the bypass cable, due to the small space of the European-style branch box and the inlet hole of the ring network cabinet, and the large volume of the cable terminal enclosed with the bypass cable, it is impossible to enter the European-style branch through the inlet hole Boxes and ring network cabinets, making it more difficult to connect bypass cables to branch boxes and ring network cabinets. Often, due to the inability to implement effective connections between branch boxes, ring network cabinets and bypass cables, the scope of work is expanded, and maintenance without power failure is required. Inconvenience caused by homework
