Description

Weak current power supply transmission wire harness suitable for rail transit system Technical Field The utility model relates to the field of power transmission wiring harnesses, in particular to a weak current power transmission wiring harness suitable for a rail transit system. Background The weak current power supply transmission harness of the rail transit system is a wire assembly which is specially designed for the rail transit system (such as subways, light rails, trams and the like) and is used for transmitting weak current signals or weak current energy. These harnesses typically include a plurality of insulated conductors encased in a common sheath for ease of installation, protection and management. The interface department of power transmission pencil among the prior art does not possess waterproof and dirt-proof effect, and simultaneously, power transmission pencil length is longer, and repeated carries out the plug to power transmission pencil can lead to intertwine between the power transmission pencil many times, is difficult to the arrangement. Accordingly, a weak current power transmission harness suitable for a rail transit system is provided by those skilled in the art to solve the problems set forth in the background art. Disclosure of utility model In order to solve the technical problems, the utility model provides a weak current power supply transmission wire harness suitable for a rail public transportation system, which comprises a wire harness, wherein one end of the wire harness is provided with a connector, the outer surface of the wire harness is provided with a wire collecting mechanism, the wire collecting mechanism comprises a hollow plate and moving wheels, a plurality of moving wheels are arranged in the hollow plate, the moving wheels are alternately arranged, and the wire harness is wound on the outer surface of the moving wheels; A plurality of moving holes are formed in the lower end of the hollow plate, a fixed cover is arranged at the lower end of the hollow plate, a threaded rod is connected in a rotating mode in the fixed cover, the position, corresponding to the moving holes, of the lower end of the hollow plate is fixedly connected with a first bevel gear through the fixed cover, the outer surface of the threaded rod is in threaded connection with a threaded sleeve, the threaded sleeve is connected with the moving wheel in a rotating mode, and the threaded sleeve is connected with the hollow plate and the fixed cover in a sliding mode. Preferably, conical protective cloth is arranged on the outer surface of the connector, and annular glue is arranged on the side face of the conical protective cloth. Preferably, the side surface of the fixed cover is provided with a rotating rod, the outer surface of the rotating rod is symmetrically and rotatably connected with the supporting block, and the supporting block is fixedly connected with the fixed cover.
