technical field

The invention belongs to the technical field of under-vehicle wiring of rail transit vehicles, and in particular relates to a copper-bar type multi-wire integrated wire trough.

Background technique

At present, the under-vehicle wiring of domestic and foreign urban rail transit vehicle projects is mostly completed by cables in the form of closed cavities, wire troughs or wire trays. On the one hand, the cable wiring has problems of damage and aging during assembly, operation and maintenance. The industry mostly adopts the solution of replacing the cable insulation material and replacing the new cable. It is narrow and requires a large space for the connection of the cable. It is necessary to set up a junction box or a lead-out slot to complete the connection, and then return to the cable slot to complete the wiring. In vehicle assembly, operation and maintenance and other links, there are constant factors such as product quality, large volume, cumbersome maintainability, and poor availability.

SUMMARY OF THE INVENTION

The invention aims to optimize the wiring of the narrow structure under the vehicle, enhance the manufacturability of the overall disassembly and maintenance of the wire groove and the wiring, and prolong the overall maintenance period of the wiring under the vehicle.

In order to achieve the above purpose of the invention, the present invention provides a copper row type multi-wire integrated wire trough, which includes a wire trough body, and the wire trough body is divided into four wire cavities. It is characterized in that: the wire cavities of the wire trough body are provided with insulation The holding seat is connected to the copper bar through the insulating holding seat. The copper bar is provided with a wiring terminal. The copper bar is arranged in layers according to the voltage level, and the external cable is connected to the trunking body through the wiring terminal.

The copper bars are divided into low-voltage return busbars, high-voltage copper bars, auxiliary AC copper bars, motor frequency conversion copper bars, and feeder copper bars. The row, the motor frequency conversion copper row and the feeder copper row are respectively placed on the insulating holder in the upper part of the trunking body.

The wire cavity in the wire groove body is separated by an aluminum profile partition.

Threaded connection holes are reserved on the aluminum profile separator, and the insulating holder is assembled with the aluminum profile separator through threads.

The advantages and progress that the present invention has with respect to the prior art are as follows:

1. Compared with the existing technical structure, the copper-bar type multi-wire integrated wire trough is simplified. The use of copper-bar wire trough will better optimize the vehicle wiring weight. The integrated design of the return copper bar reduces the number of cable connection points. The electromagnetic compatibility of the conductor connection is optimized, the inductive reactance of the circuit is reduced, etc., the motor frequency conversion copper bar and the auxiliary AC copper bar are arranged in layers and the same cavity, and the space size and manufacturing economic cost have been optimized to a certain extent.

2. The copper bar-type multi-wire integrated wire trough has better overall integration performance, and provides a modular solution for the wiring and distribution of the main vehicle. It provides a better guarantee for the lightweight of vehicles, which can reduce the operating energy cost of the subway. It enhances the maintainability of vehicle design, makes the wiring integration of trunking products more independent, and improves the convenience of assembly and maintenance.

3. Copper bar type multi-line integrated wire trough, using T2 copper bar as the conductor material in the wire trough, and using the insulating holder as the supporting frame, effectively avoid the rubber aging and aging of wires and cable sheaths used in existing products. Repair problem.

4. The copper-bar type multi-wire integrated trunking adopts the layered management of voltage levels (high voltage \ frequency conversion \ AC \ low voltage), the wiring is more tidy, and the wiring confusion and misconnection and misinsertion caused by assembly and construction factors are reduced. Improves the overall electromagnetic compatibility environment of wiring.

Among them: trunk body 1, insulating holder 2, feeder copper bar 3, terminal 4, metal cable waterproof connector 5, return bus bar 6, auxiliary AC copper bar 7, external cable 8, aluminum profile partition 9, wire trough The lifting ears 10 on the side of the body, the motor frequency conversion copper bar 11, the high-voltage copper bar 12, the auxiliary AC copper bar 13, and the four wire cavities 14-17.

Detailed ways

1-3, in the specific embodiment of the present invention, the wire trough body 1 is respectively fixed to the main beam under the vehicle by the lifting lugs 10 on the side thereof. For external wiring, it is only necessary to connect the external cable 8 to the inside of the trunking body 1 through the metal cable waterproof joint 5 through the terminal 4, which greatly saves the time of overall assembly and maintenance.

According to the shortage of space under the car and the difficulty of wiring, the line groove body 1 is divided into cavities and managed in layers. The wire slot body 1 is separated into four wire cavities 14, 15, 16, and 17 by the aluminum profile partition plate 9, and an insulating holder 2 is arranged inside the wire cavity. The return bus bar 6, the auxiliary AC copper bar 7, the high voltage copper bar 12, and the motor frequency conversion copper bar 11 are managed in layers. In view of the relatively low voltage of the return bus bar 6, in order to ensure safety, it is placed at the bottom layer, and the feeder copper bar 3, auxiliary AC copper bar 7, and high-voltage copper bar 12 with higher voltage are placed close to the trunk body 1. on the upper insulating holder 2. According to the different wiring position requirements of the equipment, the feeder copper bar is set on the third layer to set the point and position of the cable connection, and the auxiliary AC copper bar is provided on the fourth layer to provide the form of cross-connection.

The insulating holder 2 is assembled by screwing on the reserved opening on the aluminum profile partition plate 9 . According to the process from high voltage to low voltage, the feeder copper bar 3, the return bus bar 6, the auxiliary AC copper bar 7, and the high voltage copper bar 12 are assembled into the trunking body 1 in layers. The use of feeder copper bar 3, return bus bar 6, auxiliary AC copper bar 7, and high-voltage copper bar 12 saves the insulation rubber layer of the cable sheath in the existing structure to the greatest extent, and relieves the high duty cycle of the conductor and the laying conditions. poor condition. And solves the problem of difficult wiring in the trunking body 1 caused by the narrow space and the difficulty in bending the cable.
