Description

Technical Field

[0001] The utility model relates to the technical field of vehicle wiring harnesses, and particularly relates to a high-voltage wiring harness for new energy vehicles that is easy to bind. Background Art

[0002] When a new energy vehicle is working, in order to enable multiple electrical components in the vehicle to work properly, relevant electrical components are connected to the main interface of the new energy vehicle through a high-voltage wiring harness.

[0003] Connect the wiring plug of the high-voltage wiring harness to the main interface of the new energy vehicle, and then connect the multiple wiring terminals on the high-voltage wiring harness to the corresponding electrical components respectively. After the connection is completed, generally, multiple wiring harnesses are directly tied together with a tie strap to prevent scattering.

[0004] However, the method of directly binding with a tie strap will cause contact between multiple wiring harnesses, and they are relatively closely attached. As a result, when multiple electrical components work simultaneously, multiple wiring harnesses are all energized to work, which leads to the phenomenon that heat accumulates easily at the binding position of the tie strap, and then the wiring harness is damaged, shortening the service life of the high-voltage wiring harness. For this reason, we propose a high-voltage wiring harness for new energy vehicles that is easy to bind. Content of the Utility Model

Specific embodiments

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] The present invention provides a Figures 1-5 new energy vehicle high-voltage wire harness that is easy to bind as shown in the figure, including a wire harness main body 101 and a separating mechanism. There are multiple wire harness main bodies 101. One end of the multiple wire harness main bodies 101 is fixedly connected with a wiring plug 801, and the other ends of the multiple wire harness main bodies 101 are all fixedly connected with wiring terminals 802. By inserting the wiring plug 801 into the main machine interface of the new energy vehicle, the interface can be divided into multiple sub-interfaces through the wire harness main body 101 and the wiring plug 801, and then different devices are connected to the wiring terminals 802.

[0025] In a preferred embodiment, the separating mechanism is arranged on the outer wall of the wire harness main body 101. The separating mechanism is used to prevent the wire harness main bodies 101 from contacting each other. The separating mechanism includes a snap ring 201. A card slot 202 is opened at the top of the snap ring 201. The card slot 202 is fan-shaped. Connecting mechanisms are arranged on both sides of the snap ring 201. The multiple wire harness main bodies 101 are respectively stuck in the card slots 202 of the multiple snap rings 201. In this way, the multiple wire harness main bodies 101 can be separated by the multiple snap rings 201. At the same time, with the cooperation of the connecting mechanism, the multiple wire harness main bodies 101 can be arranged in a horizontal array or a circular array, avoiding the phenomenon of heat accumulation caused by the mutual contact of the multiple wire harness main bodies 101, thereby improving the stability of the use of the wire harness main body 101 and extending the service life of the wire harness main body 101.

[0026] Among them, the central angle of the card slot 202 is 240°. The radius of the card slot 202 is greater than the radius of the wire harness main body 101. The opening width of the card slot 202 is smaller than the diameter of the wire harness main body 101. A protection mechanism is provided at the top of the snap ring 201. When the wire harness main body 101 is inserted into the card slot 202, when the wire harness main body 101 just comes into contact with the snap ring 201, it will cause the wire harness main body 101 to squeeze the opening of the card slot 202, causing the snap ring 201 to deform, so that the wire harness main body 101 is completely snapped into the card slot 202. At this time, the snap ring 201 is restored, which can make the snap ring 201 stably sleeved on the outer wall of the wire harness main body 101, thereby improving the stability of the use of the snap ring 201.

[0027] Among them, the protection mechanism includes a semi-circular arc surface 301, which is opened at the top of the snap ring 201. Through the setting of the semi-circular arc surface 301, when the wire harness main body 101 is snapped into the card slot 202, the wire harness main body 101 will not show damage, thereby improving the protection effect on the wire harness main body 101.

[0028] Among them, the connection mechanism includes a fixing block 403 fixedly connected to one side of the snap ring 201. Rotating shafts 404 are provided on the front and back of the fixing block 403. The other side of the snap ring 201 is symmetrically and fixedly connected with fixing plates 401. Rotating holes 402 are opened on the front of the two fixing plates 401. When adjacent snap rings 201 are connected, the rotating shaft 404 on the outer wall of one snap ring 201 is inserted into the rotating hole 402 on the outer wall of the other snap ring 201, and the connection of the two snap rings 201 can be completed. And through the rotation of the rotating shaft 404 on the inner wall of the rotating hole 402, the two snap rings 201 can rotate around the position of the rotating shaft 404 inserted into the rotating hole 402. When multiple snap rings 201 are connected in pairs, multiple wire harness main bodies 101 can be separated in a circular array, such as Figure 4 For five snap rings 201 connected in pairs, Figure 5 For six snap rings 201 connected in pairs, when multiple wire harness main bodies 101 are not connected end to end, that is, as Figure 1 shown, three wire harness main bodies 101 are separated in a horizontal array, thereby improving the applicability of the separation mechanism.

[0029] Among them, movable holes 501 are provided on both the front and back of the fixed block 403. The outer wall of the rotating shaft 404 is movably inserted and connected with the inner wall of the movable hole 501. A connecting cavity 502 is provided between the two movable holes 501. Limiting blocks 601 are fixedly connected to the opposite ends of the two rotating shafts 404. The outer walls of the two limiting blocks 601 are slidably connected with the inner wall of the connecting cavity 502. A spring 503 is arranged between the two limiting blocks 601. Through the elastic action of the spring 503, the two limiting blocks 601 are simultaneously extruded by the spring 503, so that the rotating shaft 404 can be stably inserted into the corresponding rotating hole 402, thereby improving the working stability of the connecting mechanism. Moreover, the movable hole 501 limits the limiting block 601, so that the limiting block 601 cannot enter the movable hole 501, so that the rotating shaft 404 will not be separated from the movable hole 501, further improving the working stability of the connecting mechanism.

[0030] Among them, communicating grooves 701 are symmetrically provided at the top of the fixed block 403. The interiors of the two communicating grooves 701 are both communicated with the interior of the connecting cavity 502. Sliders 702 are fixedly connected to the tops of the two limiting blocks 601. The outer walls of the two sliders 702 are respectively slidably connected with the inner walls of the two communicating grooves 701. Through the arrangement of the sliders 702, the two rotating shafts 404 can be moved above the fixed block 403, thereby improving the operation convenience of the connecting mechanism.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
