Embodiment Construction

[0017] refer to Figure 1-Figure 3 , in a specific embodiment of the present invention, the trunking body 1 is respectively fixed on the main beam under the vehicle by the lifting lugs 10 on its side. 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 for overall assembly and maintenance.

[0018] According to the shortage of space under the car and the difficulty of wiring, separate chambers and layered management are carried out in the wire slot body 1. The trunking body 1 is divided into four line cavities 14, 15, 16, and 17 by using an aluminum profile partition 9, and an insulating holding seat 2 is arranged inside the line cavity, and the feeder copper bar 3, Backflow busbar 6, auxiliary AC copper bar 7, high-voltage copper bar 12, and motor frequency conversion copper bar 11 are managed in layers. In view of the re...

Abstract

The invention discloses a copper bar type multi-wire integrated wire duct which comprises a wire duct body. The interior of the wire duct body is divided into four wire cavities. The wire duct is characterized in that insulation holders are arranged in the wire cavities of the wire duct body; the insulation holders are connected with copper bars; wiring terminals are arranged on the copper bars; the copper bars are arranged layer by layer according to voltage levels; external cables are connected into the wire duct body through the wiring terminals; layered management of voltage levels (highvoltage / frequency conversion / alternating current / low voltage) is adopted, so that wiring is tidier; wiring disorder, misconnection and misinsertion caused by assembly construction factors are reduced;and the overall electromagnetic compatibility environment of wiring is improved.

Description

technical field [0001] The invention belongs to the technical field of under-vehicle wiring of rail transit vehicles, and in particular relates to a copper row type multi-wire integrated wire slot. Background technique [0002] At present, the under-vehicle wiring of domestic and foreign urban rail transit vehicle projects is mostly completed in the form of cables in closed cavities, wire slots or wire support slots. On the one hand, there are problems of damage and aging in cable wiring during assembly, operation and maintenance. The industry often adopts solutions to replace cable insulation materials and replace new cables. When the cable connection needs a large space, it is necessary to set up a junction box or lead-out trunking to complete the connection, and then return to the trunking to complete the wiring. In multiple links such as vehicle assembly and operation and maintenance, there are constant factors such as product quality, large size, cumbersome maintainabi...
