Description

Technical Field

[0001] The utility model relates to the field of construction engineering, in particular to building electrical construction wiring. Background Art

[0002] Building electrical construction includes the laying of lines for all electrical systems in the building. According to the building electrical design drawings, cable laying construction is carried out at designated locations. The wire conduits are generally cast in the building structure, and the cables are passed through the conduits through threading equipment. This pre-buried method requires excavation of the building surface for repairs if problems arise with the cables later.

[0003] In the prior art, one way of wiring an electrical system line is to run it on the top, that is, to achieve line laying through a suspended ceiling. Generally, a junction box is installed on the top of a building, and the cables are laid in the junction box, such as the patent document with publication number CN116031809A and the patent document with publication number CN113629648B. Since there are some requirements for bending and turning the cables during cable laying, if the turning angle is not a right angle, the junction box needs to be cut with sharp corners on site to meet the connection requirements of the junction box, and the construction is relatively cumbersome. During the cable turning process, most of the cables are directly bent and connected inside the device. The sharp junction of the junction box may cause damage to the cable protective layer, and during the bending process, special tools must be operated, which may also damage the outer protective layer of the cable, affecting the line laying efficiency, and may also affect the construction quality, leaving safety hazards, and then affecting subsequent use (application publication number CN117477467A). Utility Model Content

The cables are bent by passing around the winding pole in the transfer unit shell. The bent cables then enter the buried unit connected to the other side of the transfer unit shell.

[0007] The utility model is provided with a transfer unit with a winding column, which bends the cable laid in the buried unit, and this bending will not cause damage to the cable protective layer, and the construction is convenient. The transfer unit shell with a polygonal structure can meet the bending of cables at different angles and the direction of different paths.

Afterwards, the upper buried unit component is sleeved on the lower buried unit component, so that the buried unit is in a closed state. Specifically, the snap-in convex portion of the upper buried unit component cooperates with the snap-in groove of the lower buried unit component to realize the snap-in connection between the upper buried unit component and the lower buried unit component.

[0009] A wire clamping member is provided in the buried unit, and the wire clamping member includes an upper part and a lower part.

[0010] The left and right sides of the clamping piece are clamped in the buried unit. After the upper and lower parts of the clamping piece are closed to clamp the cable, it is clamped into the lower part of the buried unit, and then the upper part of the buried unit is clamped with the lower part of the buried unit.
