Highway tunnel illumination distribution system and branch module

Abstract

The invention provides a highway tunnel illumination distribution system and branch modules; a flat cable and branch modules are employed, thus realizing modularization branch connection; the construction becomes simple, fast and reliable; the system comprises a cable bridge stand, a round cable, a feed interface, the flat cable, a flat cable support, an A-phase branch module, a B-phase branch module, a C-phase branch module, an end seal, and branch module matching plugs; each system contains a plurality of branch modules and corresponding matching plugs. By using the system, one branch connection can be finished within only 1 minute, thus improving the work efficiency by 50-60 times when compared with a conventional method.

Description

technical field [0001] The invention relates to the field of tunnel lighting power distribution, in particular to a highway tunnel lighting power distribution system and a branch module. Background technique [0002] In the prior art, in domestic expressway tunnel lighting distribution, ordinary round cables are often placed in the bridge frame, and branch joints are made on site to lead out branch lines to supply corresponding lighting fixtures. Some of the branch wires drawn from the branch connector are directly connected to the lighting lamp, and some are connected to the socket. The former is not easy to check and maintain, and the latter is mostly an ordinary socket, so it is difficult to guarantee waterproof and moisture-proof. [0003] At present, there are three methods for making branch joints on site: 1. Strip the cable sheath, strip off the conductor insulation respectively, crimp three groups of main lines and branch lines with three 'C' type clips, respectivel...

AI Technical Summary

Problems solved by technology

For these three, in the process of making joints, the five stranded insulated wire cores of the main line must be operated with a large space distance with a hard object, which will undoubtedly cause a certain degree of damage to the conductor insulation. greater chance of failure

These three methods not only take a long time to work, but also require operators with certain skills. Even so, the performance of multiple joints cannot be guaranteed to be consistent, and the quality is difficult to control.

And because of high-altitude operations, these are undoubtedly difficult and cumbersome, and consume a lot of man-hours

The branch joints made by the first method are small in size, but because of the manual wrapping insulation, the moisture-proof sealing performance is poor; the branch joints made by the latter two methods are large and bloated

If the sealant is not poured, it will not be moisture-proof; if the sealant is poured, the heat dissipation of the joint will be poor

In addition, if the main line and branch line conductors are non-round cores, piercing clamps and T clamps are not applicable
