Electrical cabinet of cab

Abstract

The invention relates to an electrical cabinet applicable to a cab. The electrical cabinet comprises a cuboid outer frame, and the cuboid outer frame is formed by combining a rectangular top frame, a rectangular bottom frame and a plurality of parallel stand columns. Waist beams perpendicular to the stand columns are arranged in the middles of two side frames of the outer frame respectively, and an internal secondary frame is fixed to the upper portion of the outer frame. An internal panel is fixed to the lower portion of the internal secondary frame, and a plurality of first wiring ducts perpendicular to the stand columns of the outer frame body are fixed to the internal panel. A plurality of second wiring ducts parallel with or perpendicular to the stand columns of the outer frame body are arranged in the side frames of the outer frame. The first wiring ducts are communicated with the second wiring ducts perpendicular to the stand columns of the outer frame body. Electrical products in the electrical cabinet are distributed evenly in order, the wiring directions are clear and orderly, and the electrical cabinet of the cab is convenient to maintain in the later stage due to the design.

Description

technical field [0001] The invention relates to an electrical cabinet, in particular to an electrical cabinet suitable for a driver's cab. Background technique [0002] There are a large number of electrical equipment and related cables carried by the electrical cabinet of the driver's cab on the rail vehicle. With the increase of electrical functions of rail vehicles. Equipment such as chassis equipment, disc-shaped equipment, a large number of low-voltage electrical components, and various electrical connection components need to be installed in the electrical cabinet of the driver's cab. The electrical cabinet in the driver's cab should not only play the role of a switchboard, but also serve as an installation carrier for large-scale equipment in various systems on the vehicle. The frame structure design scheme of the existing electrical cabinets on rail vehicles is relatively simple. For example, the Chinese patent with the publication date of 2014.3.5 and the applicat...

Problems solved by technology

The frame structure design scheme of the existing electrical cabinets on rail vehicles is relatively simple. For example, the Chinese patent with the publication date of 2014.3.5 and the application number of 201310602805.9 discloses "a D-shaped electrical cabinet". Although the design takes into account the installation stability , but the wiring is complicated and the maintenance is poor; there is also an electrical cabinet, such as Figure 1-2 Shown: There is no fixed main wiring harness area, resulting in intricate wiring in the cabinet, and the wiring harness cannot be horizontally flat and vertically

At the bend of the wire harness, the main wire harness is too thick, the stress is too large, and the aesthetics is poor

The wire harness that flows from the main wire harness to each equipment area is easy to be too thick, knotted, and squeezed

The arrangement of equipment and wiring in the entire cabinet is not coordinated, the space utilization rate is low, the maintainability and aesthetics are poor, the space in the cabinet is airtight, and the heat dissipation is poor
