Description

Technical Field

[0001] This utility model belongs to the field of rail transit vehicle technology, and more specifically, it relates to a rail transit vehicle wiring harness and connector fixing bracket. Background Technology

[0002] Rail transit vehicles involve a support structure for fixing pipelines based on the coupler mounting base. The main function of this structure is to fix the wiring harness and connectors from the coupler to the electrical cabinet. The coupler adopts a fully automatic close-connection coupler-slower device that integrates mechanical, pneumatic, and electrical systems. The electrical connector is a functional module in the fully automatic close-connection coupler-slower device that performs automatic connection and disconnection of circuits between train sets. With the automatic coupling and uncoupling of the mechanical coupler, the automatic coupling and disconnection of electrical lines between train sets is realized. The realization of the coupler function is inseparable from the wiring harness connection, and ensuring the reliable fixation of the wiring harness during vehicle operation is very important. In existing vehicles, the coupler wiring harness is fixed by pipe clamps, one end of the connector is mounted on the fireproof plate at the end of the vehicle, and the other end of the connector is directly plugged into it, with fixation relying solely on the connector's own shell. There is a risk of connector failure during vehicle operation, and replacing the connector at the fireproof plate end is labor-intensive. Therefore, it is necessary to design a structure to optimize this process.

[0003] The existing vehicle coupler-to-electrical cabinet wiring typically requires connectors to connect the coupler harness and the electrical cabinet harness. Connectors are divided into pin modules and socket modules. The socket module connector (equipment-side connector) is fixedly mounted on a fireproof plate, while the pin module connector (harness-side connector) connects to the coupler harness. The equipment-side connector is entirely mounted on the fireproof plate of the vehicle's end structure, with the electrical cabinet mounted above it. The harness-side connector directly plugs into the equipment-side connector and connects to the electrical cabinet to achieve electrical circuit connectivity. This presents the following technical drawbacks: 1) Harness-side connector fixation issues. The coupler harness-side connector is only fixed to the equipment-side connector by its own shell, posing a risk of connector failure under long-term vehicle operation. 2) Maintainability issues. The equipment-side connector module is mounted on the fireproof plate, resulting in significant workload for later maintenance and replacement. This requires disassembling the electrical cabinet, re-verifying the relevant harness insulation withstand voltage test, and re-adjusting the signal equipment within the electrical cabinet.

[0004] Existing technology includes a specification titled "Wire Harness Installation Device and Rail Transit Vehicle," with publication number CN218386522U. This specification discloses a wire harness installation device comprising a fastener, a clamp disposed on the fastener for allowing the wire harness to pass through, and an adjusting pad disposed on the fastener and adjacent to the clamp, wherein at least one clamp is provided. The wire harness installation device of this invention has a simple structure, facilitates the installation of wire harnesses on rail transit vehicles, ensures reliable wire harness fixation, and reduces weight and cost. This invention also discloses a rail transit vehicle. However, this technology does not address the technical problem and solution of this application. Utility Model Content
