Description

Technical Field

[0001] This utility model relates to the field of wiring harness technology for new energy vehicles, and more specifically, to a wiring harness assembly for new energy vehicles with multiple protection structures. Background Technology

[0002] New energy vehicle wiring harnesses include high-voltage wiring harnesses and low-voltage wiring harnesses. High-voltage wiring harnesses are typically used for the connection between the battery and the motor, carrying high voltage and current. High-voltage wiring harnesses are usually equipped with shielding layers to reduce the radiation interference generated by the high-voltage wiring harness itself, and also to reduce the impact of external electromagnetic interference on the wiring harness. Currently, there are three common shielding methods for high-voltage wiring harnesses. One of them is external rigid sleeve shielding. The rigid shielding sleeve can be made of aluminum tube with high thermal conductivity and light weight, which can play the role of shielding and protection at the same time.

[0003] Existing rigid shielding sleeves lack flexibility, making it difficult to adapt to changing shapes or orientations in complex layouts or confined spaces. Due to this lack of flexibility and adaptability, the installation and connection of rigid shielding sleeves may require more time and specialized tools, increasing construction costs and complexity. Therefore, we propose a new energy vehicle wiring harness assembly with a multi-layered protection structure. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a new energy vehicle wiring harness assembly with multiple protection structures to solve the technical problem of poor functionality of existing rigid shielding sleeves.

[0005] To solve the above technical problems, this utility model provides the following technical solution: a new energy vehicle wiring harness assembly with multiple protection structures, including a high-voltage conductor, a spiral shielding layer detachably connected to the outside of the high-voltage conductor, a flexible binding layer detachably connected to the outside of the spiral shielding layer, and metal shielding mesh strips fixedly connected to both ends of the spiral shielding layer;

[0006] The spiral shielding layer includes a rigid spiral corrugated tube, and spiral connecting sleeves and spiral connecting parts are fixedly connected to the spiral edges on both sides of the rigid spiral corrugated tube, respectively. The cross-sections of the spiral connecting sleeves and spiral connecting parts are both "Ω" and can be connected to each other by snapping.

[0007] The flexible restraint layer includes a flexible mesh sleeve, with restraint loops fixedly connected to both ends of the flexible mesh sleeve. The flexible mesh sleeve and the restraint loops are detachably connected by snap fasteners at their side openings.

[0008] Preferably, the high-voltage conductor includes a conductor, and the conductor is wrapped with an insulating layer.

[0009] Preferably, the spiral connecting sleeve includes a first spiral edge, which is fixedly installed on one side of the spiral edge of the rigid spiral corrugated pipe, and a spiral buckle sleeve is integrally connected to the first spiral edge.

[0010] Preferably, the spiral connector includes a second spiral edge, which is fixedly installed on the spiral edge of the other side of the rigid spiral corrugated pipe, and a spiral buckle is fixedly connected to the outside of the second spiral edge;

[0011] The spiral fastener is made of flexible material, and a third spiral edge is integrally connected to the other side of the second spiral edge. The third spiral edge is curved in the direction opposite to the second spiral edge.

[0012] Preferably, the flexible sleeve and the side opening of the binding ring are respectively fixedly connected to a first buckle sleeve and a side strip at both ends, and a first buckle member is fixedly connected to the side strip. The cross-sections of the first buckle sleeve and the first buckle member are both arrow-shaped and can be matched and connected to each other.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model achieves a shielding effect by using a rigid spiral corrugated tube fitted over a high-voltage conductor. While providing excellent pressure resistance and protection, it also exhibits good flexibility and extensibility, making it suitable for complex layouts and space-constrained environments. The rigid spiral corrugated tube can be quickly installed and removed from the middle of the high-voltage conductor via a spiral connecting sleeve and spiral connector that are Ω-shaped on both sides and can be interlocked. The outer side is secured by a flexible binding layer with snap-fit ​​connections at the opening, increasing the protective effect while preventing the spiral shielding layer from loosening, thus solving the problem of poor functionality in existing rigid shielding sleeves.

[0015] 2. This utility model also achieves the effect of quick installation of rigid spiral corrugated pipe and side sealing after installation by designing a spiral connecting sleeve and spiral connecting piece structure in the shape of "Ω" that can be matched and snapped together, thereby further solving the problem of poor functionality of existing rigid shielding sleeves.

[0025] like Figures 1 to 4 As shown, the present invention relates to a new energy vehicle wiring harness assembly with multiple protection structures, including a high-voltage conductor 1, a spiral shielding layer 2 detachably connected to the outside of the high-voltage conductor 1, a flexible binding layer 3 detachably connected to the outside of the spiral shielding layer 2, and metal shielding mesh strips 7 fixedly connected to both ends of the spiral shielding layer 2.

[0026] The spiral shielding layer 2 includes a rigid spiral corrugated tube 4. The spiral connecting sleeve 5 and the spiral connecting piece 6 are fixedly connected to the spiral sides of the rigid spiral corrugated tube 4 respectively. The cross-sections of the spiral connecting sleeve 5 and the spiral connecting piece 6 are both "Ω" and can be connected to each other by snapping.

[0027] The flexible binding layer 3 includes a flexible mesh 301, with binding loops 302 fixedly connected to both ends of the flexible mesh 301. The flexible mesh 301 and the binding loops 302 are detachably connected by snap-fit ​​at the side openings. This utility model achieves a shielding effect by using a rigid spiral corrugated tube 4 that is fitted over the high-voltage conductor 1. While providing good pressure resistance and protection, it also has good flexibility and extensibility, making it suitable for complex layouts and environments with limited space. The rigid spiral corrugated tube 4 can be quickly installed and removed from the middle of the high-voltage conductor 1 through a spiral connecting sleeve 5 and a spiral connecting piece 6 that are Ω-shaped on both sides and can be snap-fitted together. The outer side is bound by the flexible binding layer 3 that is snap-fitted at the opening, which increases the protection effect and prevents the spiral shielding layer 2 from loosening.

[0028] Furthermore, the high-voltage conductor 1 includes a conductor 101, which is wrapped with an insulation layer 102. The shielding method is achieved by using an outer shielding sleeve for the conductor. However, the high-voltage conductor 1 itself has its shielding layer removed. After the shielding layer is removed, the outermost wire sheath, which serves to protect and insulate, is no longer needed. At this point, the structure of the high-voltage conductor 1 consists only of the insulation layer 102 and the conductor 101. For wire harness manufacturers, this simplifies the production process and reduces equipment investment.

[0029] Furthermore, the spiral connecting sleeve 5 includes a first spiral edge 501, which is fixedly installed on the spiral edge of one side of the rigid spiral corrugated pipe 4, and a spiral snap sleeve 502 is integrally connected to the first spiral edge 501.

[0030] Furthermore, the spiral connector 6 includes a second spiral edge 601, which is fixedly installed on the spiral edge of the other side of the rigid spiral bellows 4. A spiral buckle 602 is fixedly connected to the outside of the second spiral edge 601. When the buckle is connected, the first spiral edge 501 is fastened to the second spiral edge 601.

[0031] The spiral fastener 602 is made of flexible material. The third spiral edge 603 is integrally connected to the other side of the second spiral edge 601. The third spiral edge 603 is curved in the opposite direction to the second spiral edge 601. After the spiral connecting sleeve 5 and the spiral connecting piece 6 are fastened together, the upward-curving third spiral edge 603 pressed down strengthens the connection between the spiral connecting sleeve 5 and the spiral connecting piece 6, reduces the generation of connection gaps, and enhances the shielding effect.

[0032] Furthermore, the flexible mesh 301 and the binding ring 302 are respectively fixedly connected to the two ends of the side openings with a first buckle sleeve 303 and a side strip 305. A first buckle member 304 is fixedly connected to the side strip 305. The cross-sections of the first buckle sleeve 303 and the first buckle member 304 are both arrow-shaped and can be connected to each other by buckling. The flexible mesh 301 can not only bind the spiral shielding layer 2 to prevent it from loosening, but also provide appropriate cushioning when subjected to external impacts, thus playing a further protective role. Moreover, due to its mesh structure, it is easy to dissipate heat.

[0033] Working Principle: This embodiment provides a new energy vehicle wiring harness assembly with multiple protection structures. In use, this utility model achieves shielding through a rigid spiral corrugated tube 4 fitted over the high-voltage conductor 1. While providing excellent pressure resistance and protection, it also exhibits good flexibility and extensibility, making it suitable for complex layouts and space-constrained environments. First, the metal shielding mesh 7 at one end of the spiral shielding layer 2 is wrapped around the outside of the high-voltage wiring harness. The spiral shielding layer 2 is then wrapped around the outside of the high-voltage wiring harness, so that the spiral connecting sleeve 5 presses against the upper part of the spiral connector 6. The spiral buckle sleeve 502 is pressed against the spiral buckle 602 until the flexible rubber spiral buckle 602 elastically deforms and is squeezed into the spiral buckle sleeve 502, completing the buckling fixation. A third spiral edge 603 is integrally connected to the other side of the second spiral edge 601. The third spiral edge 603 curves upwards in the direction opposite to the second spiral edge 601, so that after the spiral connecting sleeve 5 and the spiral connector 6 are buckled together, the upward-curving third spiral edge 603, pressed below, enhances the spiral... The connection between the connecting sleeve 5 and the spiral connector 6 reduces the generation of connection gaps and enhances the shielding effect. Then, the metal shielding mesh 7 at the other end is wrapped around the other end of the high-voltage wire harness. The rigid spiral corrugated tube 4 can be quickly installed and removed in the middle of the high-voltage conductor 1 through the spiral connecting sleeve 5 and the spiral connector 6, which are Ω-shaped on both sides and can be connected by a snap fastener. The binding loops 302 at both ends of the flexible binding layer 3 are pressed against the metal shielding mesh 7 on both sides respectively. The arrow-shaped first snap fastener 304 is pressed into the first snap fastener sleeve 303 that matches it to complete the snap fastening. The outer side of the spiral shielding layer 2 is bound by the flexible binding layer 3 connected by a snap fastener at the opening, which increases the protection effect and prevents the spiral shielding layer 2 from loosening. It can also provide appropriate cushioning when subjected to external impacts, which can further protect it. Moreover, due to its mesh structure, it is easy to dissipate heat. When wiring is required, one end of the flexible binding layer 3 is first untied, and then one end of the spiral shielding layer 2 is untied. After wiring, the spiral shielding layer 2 and the flexible binding layer 3 can still wrap around the wiring point.

[0034] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
