Description

Branching box and have its rail vehicle

Technical Field

The utility model belongs to the technical field of railway vehicles, and particularly relates to a junction box and a railway vehicle with the same.

Background

In the traditional connection of the vehicle body underframe cables, the junction boxes are adopted, the traditional junction boxes need to be provided with pipe joints or cable fastening pieces and the like at the positions of the openings for realizing sealing, and the pipe joints or the cable fastening pieces and the like need certain installation space, so that the openings of the traditional junction boxes need to consider larger space intervals, and thus larger volume is needed to meet the requirements of the openings, the traditional junction boxes occupy large space, and the traditional junction boxes are difficult to be used for branching in some local areas with narrow space of the vehicle body underframe; secondly, the traditional outlet mode of the junction box is generally horizontal or vertical outlet, the outlet mode needs to bend the cable in a narrow local area, such as the vehicle bottom, and some cables with thicker wire diameters are easy to break after being bent.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a junction box and a railway vehicle with the same, and aims to solve the technical problem that an outgoing cable of a vehicle bottom junction box is broken due to excessive bending.

In order to achieve the purpose, the specific technical scheme of the utility model is as follows:

the utility model provides a junction box, this junction box includes the box body, the lower extreme of box body is equipped with the apron, the preceding terminal surface of box body is installed the cable and is worn to separate the subassembly, the cable is worn to separate the subassembly and is included a plurality of wire holes, form first contained angle between the axial extending direction of wire hole and the horizontal direction after the installation.

Therefore, the space interval of the wire outlet holes can be effectively controlled by arranging the cable penetrating and separating component, the volume of the junction box is reduced, the included angle is formed between the axial extension direction of the wire outlet holes and the horizontal direction, the bendable range of the cable can be effectively enlarged, and the requirement of the bending radius with the larger wire diameter can be met.

Further, a second included angle is formed between the front end face and a section perpendicular to the length direction of the box body; one side of the bottom end face of the box body, which is close to the front end face, is bent downwards to form an inclined plane.

Still further, the first included angle ranges from 10 ° to 40 °, and preferably the first included angle is 20 °.

Still further, the second included angle ranges from 10 ° to 40 °, with the second included angle preferably being 20 °.

Furthermore, a drain hole is arranged on the cover plate; the drainage can be realized without opening the cover plate during drainage.

Furthermore, a sealing element is arranged on the outlet holes, and a fastening element matched with the sealing element is further arranged on the cable penetrating and separating assembly.

Based on the same design concept, the utility model also provides a railway vehicle which comprises a vehicle body underframe, wherein a cable is arranged in a cavity of the vehicle body underframe, the junction box is arranged on the lower end face of the vehicle body underframe, the upper end of the box body is connected with the lower end face of the vehicle body underframe, and the cable penetrates through the vehicle body underframe, enters the box body and is led out from a wire outlet hole of the box body.

Therefore, the junction box is used for the wiring structure of the vehicle body underframe, can be well suitable for the narrow space of the vehicle body underframe, bends the front end surface of the junction box downwards, leads a cable to be bent downwards for outgoing, and avoids the cable from being excessively bent after outgoing and being broken.

The utility model has the following advantages: by designing the cable penetrating and separating assembly, the volume of the junction box is fully reduced, and the space under the vehicle is saved; compare in traditional junction box, with the front end face downward bending of junction box, make the axial extending direction and the horizontal direction of wire hole have the contained angle, can effectively increase the flexible scope of cable, can realize the demand of thick footpath bending radius.
