[0002] Vehicle-mounted components usually need to be well sealed during use, for example, sensor components are usually sealed by epoxy resin or glue. Since vehicle-mounted components usually need to be electrically connected to external devices through a wiring harness, multi-core wiring harnesses are widely used due to their good flexibility. Since there is an intermediate joint between the multi-core wiring harnesses, water from the outside can easily enter the gap between the cores of the multi-core wiring harness, and then enter the vehicle-mounted component, which can cause the vehicle-mounted component to fail. SUMMARY

[0003] Therefore, a vehicle, a multi-core wiring harness and an intermediate joint structure thereof are provided. The intermediate joint structure can prevent water from entering the vehicle-mounted component through the gap between the cores, ensuring that the vehicle-mounted component will not fail due to water ingress. Thus, the multi-core wiring harness using the intermediate joint structure will not be waterlogged.

Meanwhile, the first sealing part formed by the cooperation of the first sealing member and the connecting joint can seal one end of the first wire harness, so as to seal the gap in the first wire core group and the gap between the first wire core group and the first insulation layer, avoid water from entering the gap in the first wire core group, avoid water from entering the inside of the multi-core wire harness, avoid water from entering the vehicle-mounted component through the multi-core wire harness, and ensure that the vehicle-mounted component will not fail due to water.

[0028] As shown in Figure 1 and Figure 2 In one embodiment, an intermediate joint structure is provided, including a first wire harness 100, a second wire harness 200, and an intermediate connecting assembly 400. The first wire harness 100 includes a first wire core group 110 for electrically connecting with a vehicle-mounted component (not shown), and a first insulation layer 120 sleeved on the first wire core group 110; the second wire harness 200 includes a second wire core group 210 for electrically connecting with the outside world, and the second wire core group 210 can be electrically connected with the first wire core group 110 to form a connecting joint 300; the intermediate connecting assembly 400 includes a first sealing member 410 sleeved on the first insulation layer 120 and the connecting joint 300, and the first sealing member 410 can cooperate with the connecting joint to form a first sealing portion 420 for sealing one end of the first wire harness 100.

[0029] The intermediate joint structure of the above embodiment electrically connects one end of the first wire core group 110 of the first wire harness 100 with the vehicle-mounted component, electrically connects one end of the second wire core group 210 of the second wire harness 200 with the outside world, and electrically connects the other end of the first wire core group 110 with the other end of the second wire core group 210, thereby achieving electrical connection between the vehicle-mounted component and the outside world. At the same time, the first sealing portion 420 formed by the cooperation of the first sealing member 410 and the connecting joint 300 seals one end of the first wire harness 100, thereby sealing the gap in the first wire core group 110 and the gap between the first wire core group 110 and the first insulation layer 120, avoiding water from entering the gap in the first wire core group 110, thereby avoiding water from entering the vehicle-mounted component through the gap between the first wire core group 110, and ensuring that the vehicle-mounted component will not fail due to water ingress.

[0030] It should be noted that, as shown in Figure 1 and Figure 2As shown, the first wire core group 110 can be provided to include a plurality of first wire cores 111 arranged at intervals, and the first wire core 111 can be provided as a copper wire core or an aluminum wire core; the second wire can be provided to include a plurality of second wire cores 211 arranged at intervals, and the second wire core 211 can be provided as a copper wire core or an aluminum wire core; it is only required to satisfy the conduction of current. The first insulation layer 120 can be made of polyvinyl chloride, polyethylene or the like, and it is only required to satisfy the corresponding insulation requirements. The electrical connection of the first wire core group 110 and the second wire core group 210 can be that the first wire core 111 of the first wire core group 110 is connected in one-to-one correspondence with the second wire core 211 of the second wire core group 210, which can be achieved by welding or fusion. The first sealing member 410 is provided with a mounting cavity, one end of the first insulation layer 120 is inserted into the mounting cavity of the first sealing member 410, and then the first sealing member 410 is matched with the connecting joint to form the first sealing part 420, thereby achieving the sealing of the gap of the first wire core group 110. Sealing one end of the first wire harness 100 means sealing the gap between the first wire core 111 of the first wire core group 110 and the gap between the first insulation layer 120 and the first wire core 111 by using the first sealing part 420.

[0031] The sealing cooperation of the first sealing member 410 and the connecting joint 300 is preferably achieved by fusion such as welding, which is convenient, fast and reliable in sealing.

[0032] In one embodiment, the first sealing member 410 and the connecting joint 300 form the first sealing part 420 by heat fusion. In this way, after the first sealing member 410 is sleeved on the first insulation layer 120 and the connecting joint 300, the first sealing member 410 and the connecting joint 300 can be heat fused together by ultrasonic welding or friction welding, i.e. the molten material formed by melting the first sealing member 410 and the connecting joint 300 (the first wire core 111 and the second wire core 211) is used to seal one end of the first wire harness 100, thereby preventing water from entering the gap between the first wire core 111. The ultrasonic welding method can reduce the hot air heat fusion process.

[0033] The first sealing member 410 can be provided in a tubular or cylindrical shape, which can only be able to be sleeved on the first insulation layer 120 and the connecting joint 300, and the first sealing member 410 can be matched with the connecting joint 300 to form the first sealing part 420.

[0034] In one embodiment, the first sealing member 410 is provided as a copper pipe or an aluminum pipe. In this way, when the copper pipe or the aluminum pipe is welded at the connection with the connecting joint 300 by ultrasonic welding or the like, the contact part or the whole can be molten and integrated, and the sealing effect is good.

[0035] As shown in FIG. 1, the first wire harness 100 includes a first wire core group 110, a second wire core group 210, a first insulation layer 120, a first sealing member 410 and a connecting joint 300. Figure 1 and Figure 2As shown, on the basis of any of the above embodiments, the intermediate connecting assembly 400 further comprises a second sealing member 440 arranged between the first sealing member 410 and the first insulation layer 120. In this way, the gap between the first sealing member 410 and the first insulation layer 120 is sealed by the second sealing member 440, which can prevent water from entering the gap of the first core group 110 through the gap between the first sealing member 410 and the first insulation layer 120, and has a good waterproof effect.

[0036] The second sealing member 440 seals the first sealing member 410 and the first insulation layer 120, and can be arranged in the form of a sealing ring or a sealing sleeve, as long as it can achieve a tight seal.

[0037] In one embodiment, the second sealing member 440 is arranged as a second elastic sealing sleeve. In this way, when the first sealing member 410 is sleeved on the first insulation layer 120, the second elastic sealing sleeve can be squeezed to deform elastically, thereby increasing the contact area of the second elastic sealing sleeve with the first insulation layer 120 and the first sealing member 410, and improving the sealing effect and the waterproof effect. The second elastic sealing sleeve can be made of rubber or silicone.

[0038] On the basis of any of the above embodiments, the first sealing member 410 is provided with a second guide portion (not shown) for guiding the first insulation layer 120 to enter. In this way, the second guide portion can make the first sealing member 410 smoothly and quickly sleeved on the first insulation layer 120, without damaging the surface of the first insulation layer 120, and avoiding the problems of electric leakage or short circuit. The second guide portion can be arranged as a guide slope or a guide arc surface, and the second guide portion is arranged at the opening edge position of one end of the first sealing member 410.

[0039] As shown, on the basis of any of the above embodiments, the intermediate connecting assembly 400 further comprises a second sealing member 440 arranged between the first sealing member 410 and the first insulation layer 120. In this way, the gap between the first sealing member 410 and the first insulation layer 120 is sealed by the second sealing member 440, which can prevent water from entering the gap of the first core group 110 through the gap between the first sealing member 410 and the first insulation layer 120, and has a good waterproof effect. Figure 2As shown, based on any of the above embodiments, the second wire harness 200 further includes a second insulating layer 220 sleeved on the second wire core group 210. Thus, the second insulating layer 220 can protect the second wire core group 210, preventing short circuits or leakage caused by exposure. The second insulating layer 220 can be made of materials such as polyvinyl chloride or polyethylene, as long as it meets the corresponding insulation requirements. A first sealing member 410 is sleeved on the first insulating layer 120, the connecting joint 300, and the second insulating layer 220, and the first sealing member 410 can cooperate with the connecting joint 300 to form a first sealing portion 420 for sealing one end of the first wire harness 100 and one end of the second wire harness 200. Thus, the first sealing part 420 not only seals one end of the first wire harness 100, thereby sealing the gaps in the first core group 110 and preventing water from entering the gaps in the first core group 110 and thus preventing water from entering the vehicle components through the gaps between the first core groups 110; it also seals one end of the second wire harness 200, thereby sealing the gaps in the second core group 210 and preventing water from entering the gaps in the second core group 210 and thus preventing water from entering the external vehicle components through the gaps between the second core groups 210, resulting in better waterproofing. Similarly, sealing one end of the second wire harness 200 means using the first sealing part 420 to seal the gaps between the second cores 211 of the second core group 210, and using the first sealing part to seal the gap between the second insulation layer 220 and the second cores 211.

[0040] In one embodiment, the first seal 410 is provided with a first guide portion (not shown) for guiding the second insulating layer 220 into place. Thus, the first guide portion allows the first seal 410 to be smoothly and quickly fitted onto the second insulating layer 220 without damaging the surface of the second insulating layer 220, avoiding leakage or short circuit problems. The first guide portion can be configured as a guide slope or a guide arc surface, and is located at the opening edge of the other end of the first seal 410.

[0041] like Figure 2 As shown, in one embodiment, the intermediate connection assembly 400 further includes a first sealing member 430 disposed between the first sealing member 410 and the second insulating layer 220. Thus, by using the first sealing member 430 to seal the gap between the first sealing member 410 and the second insulating layer 220, water can be further prevented from entering the gap of the second core assembly 210 through the gap between the first sealing member 410 and the second insulating layer 220, further preventing water from entering external electrical components.

[0042] The first sealing member 430 seals the first sealing member 410 and the second insulation layer 220. The first sealing member 430 can be in the form of a sealing ring or a sealing sleeve, as long as it can achieve a tight seal.

[0043] In one embodiment, the first sealing member 430 is a first elastic sealing sleeve. When the first sealing member 410 is sleeved on the second insulation layer 220, the first elastic sealing sleeve can be squeezed to elastically deform, thereby increasing the contact area of the first elastic sealing sleeve with the second insulation layer 220 and the first sealing member 410, and achieving better sealing and waterproof effects. The first elastic sealing sleeve can be made of rubber or silicone.

[0044] In one embodiment, a multi-core wire harness is also provided, which includes the intermediate joint structure of any of the above embodiments.

[0045] The multi-core wire harness of the above embodiments electrically connects one end of the first wire core group 110 of the first wire harness 100 with the vehicle-mounted component, electrically connects one end of the second wire core group 210 of the second wire harness 200 with the outside world, and electrically connects the other end of the first wire core group 110 with the other end of the second wire core group 210, thereby achieving electrical connection between the vehicle-mounted component and the outside world. Meanwhile, the first sealing member 410 and the connecting joint 300 cooperate to form the first sealing portion 420 to seal one end of the first wire harness 100, thereby sealing the gaps in the first wire core group 110 and the gaps between the first wire core group 110 and the first insulation layer 120, preventing water from entering the gaps in the first wire core group 110, and thereby preventing water from entering the inside of the multi-core wire harness and entering the vehicle-mounted component through the multi-core wire harness, ensuring that the vehicle-mounted component will not fail due to water ingress.

[0046] In one embodiment, a vehicle is also provided, which includes the multi-core wire harness of the above embodiments.

[0047] When the vehicle-mounted component is electrically connected with the outside world by the multi-core wire harness of the above embodiments, water can be prevented from entering the gaps in the first wire core group 110, thereby preventing water from entering the inside of the multi-core wire harness and further preventing water from entering the vehicle-mounted component, ensuring that the vehicle-mounted component will not fail due to water ingress, and achieving good waterproof performance.

[0048] It should be noted that the above multi-core wire harness can be applied not only to vehicles such as cars and motorcycles, but also to other electrical equipment that requires the use of a multi-core wire harness, as long as it meets the waterproof requirement.

[0049] Any combination of the technical features in the above embodiments can be made, and for the sake of brevity, not all possible combinations are described above. However, any combination of features described above is deemed to be within the scope of the present disclosure, as long as such a combination is not obviously contradictory.

[0050] The above embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a restriction on the scope of the patent. It should be pointed out that for ordinary skilled persons in the art, some modifications and improvements can be made without departing from the concept of the present application, and these are within the protection scope of the present application. Therefore, the protection scope of the present application patent should be subject to the appended claims.
