Description
Technical Field
[0001] The utility model relates to a wiring harness structure design in an automobile circuit, in particular to a spiral wiring harness structure. Background Art
[0002] In traditional wiring harness technology, wiring harnesses are usually formed by crimping copper contact terminals (connectors) with wires and cables, and then externally injection-molded insulators. This structure is generally called a "circuit group". However, with the increasing degree of automotive electronics, higher requirements are placed on the reliability and protection of wiring harnesses, especially in automotive steering systems under dynamic environments.
[0003] In the automotive steering system, the wiring harness needs to be stably and flexibly connected between the fixed end and the moving end. The traditional wiring harness connection method may not meet the durability requirements under dynamic stress and complex environments. In order to solve this problem, it is urgent to propose a spiral tube telescopic mechanism to adapt to the stretching and recovery requirements of the steering module during the steering process. Utility Model Content
[0004] The purpose of the utility model is to provide a spiral wiring harness structure in order to overcome the defects of the above-mentioned prior art. The spiral wiring harness body is realized by injection molding technology, which not only enhances the elasticity of the wiring harness, but also improves its adaptability in the automobile steering module.
[0005] The purpose of the utility model can be achieved through the following technical solutions:
[0006] The utility model provides a spiral wire harness structure, comprising a spiral wire harness body, a fixed connection element arranged at a first connection end of the spiral wire harness body, and a movable connection element arranged at a second connection end of the spiral wire harness body;
[0007] The fixed connection element can be fixed to the inactive part of the steering module of the vehicle, and the first connection end is connected to the wiring harness of the inactive part of the steering module;
[0008] The movable connection element can be fixed to the movable part of the steering module of the automobile, and the second connection end is connected to the wiring harness of the movable part of the steering module.
[0009] Furthermore, the spiral wire harness body includes a wire harness inner core and a plastic material injection-molded on the outside of the wire harness inner core.
[0010] Furthermore, the first connection end of the spiral wiring harness body is fixed to an inactive portion of a steering module of an automobile through a fixed connection element.
[0011] Furthermore, the second connection end of the spiral wiring harness body is fixed to the movable part of the vehicle steering module through a movable connection element.
[0012] Furthermore, the fixed connection element includes a first fixing plate and a first fastener, and the first fastener fixes the first fixing plate to an inactive portion of the vehicle steering module.
[0013] Furthermore, a first limiting buckle is provided on the first fixing plate, and the first connecting end is limited in the first limiting buckle.

[0016] Furthermore, the spiral wire harness body is one spiral wire harness or two parallel spiral wire harnesses.
[0017] Furthermore, the plastic material is an elastic plastic material.
[0018] Compared with the prior art, the utility model has the following technical advantages:
[0019] 1) The spiral harness structure of the utility model realizes the spiral shape of the harness body through injection molding technology. This design not only enhances the elasticity of the harness, but also improves its adaptability in the automotive steering module. The two ends of the fixed structure are respectively fixed to the fixed end and the movable end of the steering module, ensuring the stability of the harness during the steering process. When a pulling force or a pushing force is applied to the movable end, the spiral harness structure can be flexibly stretched and contracted to adapt to the activity requirements of the steering module. This design significantly improves the service life and reliability of the harness, and reduces the maintenance cost and time caused by harness damage.
[0020] 2) When the pulling or pushing force applied to the moving end disappears, the spiral harness structure can quickly return to its original state without additional operation or adjustment. This adaptive recovery mechanism ensures the stability and consistency of the harness during long-term use, while also reducing the potential risk of failure caused by harness deformation or damage. In addition, the injection-molded spiral structure also provides additional protection to prevent the harness from being damaged in complex environments, further improving the overall performance and safety of the automotive steering module.

[0021] Figure 1 This is a schematic diagram of the first type of spiral wiring harness structure in the utility model;
[0022] Figure 2 This is a second schematic diagram of the spiral wiring harness structure in the present invention.
[0023] In the figure: 1. spiral wiring harness body, 2. fixed connecting element, 3. movable connecting element. DETAILED DESCRIPTION
[0024] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. Any features such as preparation means, materials, structures or composition ratios not clearly described in this technical solution are considered to be common technical features disclosed in the prior art.
[0025] Example 1
[0026] The spiral wire harness structure in Example 1 includes a spiral wire harness body 1, a fixed connection element 2 provided at a first connection end of the spiral wire harness body 1, and a movable connection element 3 provided at a second connection end of the spiral wire harness body 1, see Figure 1 .
[0027] The main body of the harness is in a spiral shape, and the inner core of the harness is wrapped with elastic plastic material through injection molding technology. This structure not only gives the harness a high degree of elasticity, but also provides the necessary protection to prevent the harness from being damaged during the steering process. When the active part of the steering module is subjected to tension or thrust, the spiral harness structure can be stretched accordingly to adapt to the movement of the module. Once the external force disappears, due to the elasticity of the main body of the harness, the harness will automatically return to its original shape without the need for additional adjustment or maintenance.
[0028] The fixed connection element 2 can be fixed to the inactive part of the steering module of the automobile, and the first connection end is connected to the wiring harness of the inactive part of the steering module; the movable connection element 3 can be fixed to the active part of the steering module of the automobile, and the second connection end is connected to the wiring harness of the active part of the steering module. This fixing method ensures the stability and reliability of the wiring harness in the steering module.
