Description

Technical Field

[0001] This utility model relates to the field of wire trough technology and provides a modular structure for wire troughs. Background Technology

[0002] To protect the wiring harnesses of rail vehicles, cable trays are typically installed on the vehicle, covering the wiring harnesses. However, when designing and installing these cable trays, their shape must be compatible with the wiring harness's routing and the layout of the surrounding space to avoid interference between the cable trays and surrounding components. For example, for wiring harnesses located at the bottom of the rail vehicle, cable trays are installed at the bottom of the car body, with the cable trays running through the vehicle. To avoid obstructing the underframe sleeper beam area and the bogie's motion envelope, the cable trays need to be designed with a special shape.

The length of the processed wire groove is fixed, and it only has one shape, which cannot be adjusted according to the wiring requirements of the wire harness. Since the wire harness routing and the layout of the surrounding space are different for each model and even each rail vehicle, the required shape of the wire groove is different. It is necessary to design wire grooves and stamping molds of corresponding shapes, resulting in poor interchangeability and high processing costs.

[0004] Therefore, how to solve the problem that the shape and length of the wire trough in the relevant technology cannot be arbitrarily adjusted according to the wiring requirements of the wire harness has become an important technical problem to be solved by those skilled in the art.

[0032] The embodiments of the present application will be further described in detail below with reference to the drawings and examples. The following examples are used to illustrate the present application, but cannot be used to limit the scope of the present application.

[0033] The embodiments of the present application will be further described in detail below with reference to the drawings and examples. The following examples are used to illustrate the present application, but cannot be used to limit the scope of the present application. Figures 1 to 9 The wire slot modular structure of the present application is described below.

[0034] As shown in Figures 1 to 9 The wire slot modular structure provided by the embodiments of the present application includes at least two wire slot assemblies 1, and each wire slot assembly 1 includes two wire slot modules 2.

[0035] Specifically, each wire slot module 2 has a wire passing channel for wire harness to pass through, and the wire passing channels of the two adjacent wire slot modules 2 are correspondingly communicated.

[0036] The two ends of any one wire slot assembly 1 can be rotatably connected with the ends of the remaining wire slot assemblies 1, so that the wire slot assemblies 1 can be connected in series, and any two adjacent wire slot assemblies 1 can rotate relative to each other, and the relative rotation axes of any two adjacent wire slot assemblies 1 are arranged along the reference direction, so that the wire slot formed by connecting the wire slot assemblies 1 can be deformed in a first plane, and the first plane is perpendicular to the reference direction, and the reference direction is indicated by the direction of m in Figure 1 、 Figure 2 and Figure 6 .

[0037] The two wire slot modules 2 of the wire slot assembly 1 are rotatably connected, and the relative rotation axes of the two wire slot modules 2 are perpendicular to the reference direction. Thus, the wire slot formed by connecting the wire slot assemblies 1 can be deformed in a second plane or a second curved surface, and the second plane and the second curved surface are parallel to the reference direction.

[0038] In this way, the modular design of the wire slot is realized, and the number of wire slot assemblies 1 can be selected according to the length of the target wire slot. The selected wire slot assemblies 1 can be rotatably connected in series to form a target wire slot with the desired length. The target wire slot can be deformed in two different planes, and can be straight, planar curved, or spatially curved. The deformability of the target wire slot is improved, and the shape and length of the target wire slot can be adjusted as required, improving the interchangeability of the wire slot and reducing costs. The problem of the shape and length of the wire slot in the related art cannot be adjusted as required is solved.

When the locking assembly 3 is switched to the unlocked state, the two wire slot modules 2 corresponding to the locking assembly 3 can rotate relative to each other, and at this time, the target wire slot can be deformed at the position of the locking assembly 3. When the locking assembly 3 is switched to the locked state, the two wire slot modules 2 corresponding to the locking assembly 3 are relatively fixed, and at this time, the target wire slot cannot be deformed at the position of the locking assembly 3.

[0042] The connecting nut is screwed with the connecting bolt, and the relative rotation of the two wire slot modules 2 can be limited by the extrusion force and friction force between the connecting nut and the wire slot module 2 and the extrusion force and friction force between the connecting bolt and the wire slot module 2 at this time, which corresponds to the locking state of the locking assembly 3.

[0043] The connecting nut is unscrewed from the connecting bolt, and the extrusion force and friction force between the connecting nut and the wire slot module 2 and the extrusion force and friction force between the connecting bolt and the wire slot module 2 no longer exist, so that the two wire slot modules 2 can rotate relative to each other at this time, which corresponds to the unlocking state of the locking assembly 3.

[0044] In this way, the connecting bolt and the connecting nut not only realize the effect of the locking assembly 3, but also realize the rotation connection of the two adjacent wire slot assemblies 1, and the structure is simplified.
