[0047] Exemplary embodiments will be described in detail herein, and examples thereof are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention.

It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present invention described herein, for example, can be implemented in an order other than those illustrated or described herein. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products, or devices.

[0049] As described in the background art, in the protection treatment of shielded wires on some new energy commercial heavy trucks, the main wire and the shield net are respectively crimped through terminals and then inserted into the sheath, and then PVC tape is used to wind and protect the exposed shield net part between the shielded wire and the terminal or the sheath to prevent water and dust from entering the joint. However, due to the different shapes between the shielded wire and the terminal or the sheath, it is usually impossible to seal tightly with tape, and the tape is easy to loosen and leak gaps, posing risks such as water ingress corrosion and short circuit, and the overall waterproof and dustproof performance is poor.

[0050] In view of the above problems existing in the prior art, the present invention provides a wire harness assembly and a vehicle. The wire harness assembly provided by the present invention includes a shielded wire, a connecting wire, a first connector, and a first protection member. Among them, the shielded wire includes a main wire, a shielding layer, and an insulating layer arranged in sequence from the inside to the outside. By providing a lead-out section on the exposed section of the shielding layer, the lead-out section is connected to the connecting wire through the first connector and bridged through the connecting wire. The first protection member is wrapped around the end of the shielded wire to seal the exposed section and the first connector, and at least seal the exposed metal parts on the shielding layer, the connecting wire, and the first connector, playing a role in dustproof and waterproof. Part of the main wire is located outside the first protection member and is electrically connected to the electrical component for interaction. Part of the connecting wire is located outside the first protection member and is used for grounding or common line connection or connection to the grounding end of the electrical component. That is, through bridging with the connecting wire, only the local connection part between the connecting wire and the shielding layer needs to be sealed, which is easy to achieve tight sealing, thereby improving the protection reliability of the shielded wire harness.

[0051] The following introduces the exemplary application scenarios of the embodiments of the present utility model.

[0052] The wire harness assembly provided by the present utility model can be applied to, but not limited to, new energy commercial heavy-duty trucks, and can also be applied to some light vehicles such as sedans, pickups, multi-purpose vehicles MPV (Multiple purpose vehicle), and sport utility vehicles SUV (Sport utility vehicle). Specifically, the wire harness assembly provided by the present utility model can be applied to electrical components, controllers, etc. in the above-mentioned vehicle models for interaction. In this way, through the connection bridge, only the local connection between the connecting wire and the shielding layer needs to be sealed, and it is easy to achieve a tight seal, thereby improving the protection reliability of the shielded wire harness.

[0053] The following uses specific embodiments to detail the technical solutions of the present utility model. These several specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0054] In the first aspect, referring to Figures 1 - 3 as shown, the wire harness assembly provided in this embodiment includes a shielded wire 100, a connecting wire 200, a first connector 300, and a first protective member 400. The shielded wire 100 includes a main wire 110, a shielding layer 120, and an insulating layer 130 arranged in sequence from the inside to the outside. The shielding layer 120 has an exposed section, and an extraction section 101 is provided on the exposed section. The extraction section 101 is connected to the connecting wire 200 through the first connector 300. The first protective member 400 is wrapped around the end of the shielded wire 100 to seal the exposed section and the first connector 300. Part of the main wire 110 is located outside the first protective member 400 and is used for electrical connection with electrical components, and part of the connecting wire 200 is located outside the first protective member 400.

[0055] In this embodiment, the main wire 110 is used for interaction, and it can be one or more, such as twisted pairs, and it can be connected to electrical components such as a CAN box and a controller. The shielding layer 120 is used to prevent electromagnetic waves from interfering with the main wire 110. It can be one layer or multiple layers, such as aluminum foil, metal mesh, etc. The shielding layer 120 is wrapped around the periphery of the main wire 110. There is an extraction section 101 on the shielding layer 120. For example, a part of the shielding layer 120 wrapped around the periphery of the main wire 110 is peeled off to expose a part of the exposed section and twisted together to form the extraction section 101. The insulating layer 130 is used to insulate and protect the shielding layer 120, and it can be an insulating glue layer. The insulating layer 130 is wrapped around the periphery of the shielding layer 120.

[0056] The connection line 200 is used to conduct the induced current in the shielding layer 120 and plays a bridging role. It can be a wire with an insulating skin. One end of the connection line 200 is peeled off and then connected to the lead-out section 101 through the first connector 300. Among them, the first connector 300 is used to connect the connection line 200 and the lead-out section 101, and it can be a crimping terminal, a compression sleeve, etc.

[0057] The first protection part 400 is used to at least seal the exposed metal at the connection of the connection line 200 and the lead-out section 101. It can be a protective sleeve, such as a heat-shrinkable tube, etc. The first protection part 400 is wrapped around the lead-out section 101, the first connector 300, part of the main line 110, part of the insulating layer 130 and part of the connection line 200 to meet the requirements of waterproofing, dustproofing, etc.

[0058] Part of the main line 110 is located outside the first protection part 400 and is electrically connected to the electrical component for interaction. Part of the connection line 200 is located outside the first protection part 400 and is used for direct grounding. Or, multiple wire harness components can be networked and connected in a common line. For example, Figure 2 As shown, the connection lines 200 on multiple wire harness components are connected in a common line and then connected through the second connector 210, and then sealed through the third protection part 220, so that the potentials of the shielding layers 120 on each wire harness component are the same.

[0059] Among them, the second connector 210 is used to quickly compress the common line of each connection line 200, and it can be a crimping terminal, a compression sleeve, etc. After wrapping the crimping part around the periphery of each connection line 200, it is then quickly compressed through a tool to achieve quick connection. The third protection part 220 can be a heat-shrinkable tube. A section of heat-shrinkable tube is sleeved on the second connector 210 and each connection line 200, and then this part of the heat-shrinkable tube is heat-shrunk and sealed through tools such as a hot air gun. It should be noted that the common line can be grounded through another connection line 200 to make the potential zero. Or, the common line is not grounded, and it is only necessary to ensure that the potentials of the shielding layers 120 are the same, which can be determined according to actual needs.

[0060] Or, it is connected to the grounding end of the electrical component. For example, Figure 3 As shown, the main line 110 and the connection line 200 are connected to the grounding end of the electrical component through a plug-in connector. It should be noted that except for the peeled parts at both ends of the above connection line 200 that are electrically connected, the middle part should have a complete insulating protective skin.

[0061] Compared with the prior art in which the shielding net is inserted into the sheath after being crimped by the terminal, and then the exposed part of the shielding net is wrapped with PVC tape for protection, the application of the wire harness assembly in this embodiment is bridged by the connecting wire 200, and only the local part at the connection between the connecting wire 200 and the shielding layer 120 needs to be sealed. The sealing surface is small, and it is easy to achieve a tight seal, reducing the possibility of water ingress and dust ingress, thereby improving the protection reliability of the shielded wire harness, and the connection operation is simple.

[0062] To further ensure the sealing effect, part of the main wire 110, the exposed section, part of the insulating layer 130, part of the connecting wire 200 and the first connecting piece 300 can be covered by the first protective piece 400 together, and the sealing is more comprehensive.

[0063] Therefore, the wire harness assembly provided in this embodiment includes a shielded wire 100, a connecting wire 200, a first connecting piece 300 and a first protective piece 400. Among them, the shielded wire 100 includes a main wire 110, a shielding layer 120 and an insulating layer 130 which are arranged in sequence from the inside to the outside. By providing a lead-out section 101 on the exposed section of the shielding layer 120, the lead-out section 101 is connected to the connecting wire 200 through the first connecting piece 300 and bridged through the connecting wire 200. The first protective piece 400 is covered on the end of the shielded wire 100 to seal the exposed section and the first connecting piece 300, and at least seal the exposed metal parts on the shielding layer 120, the connecting wire 200 and the first connecting piece 300, playing a role in dust and water prevention. Part of the main wire 110 is located outside the first protective piece 400 and is electrically connected to the electrical component for interaction. Part of the connecting wire 200 is located outside the first protective piece 400 and is used for grounding or common line connection or connection to the grounding end of the electrical component. That is, through the bridging of the connecting wire 200, only the local part at the connection between the connecting wire 200 and the shielding layer 120 needs to be sealed, and it is easy to achieve a tight seal, thereby improving the protection reliability of the shielded wire harness.

[0064] In some embodiments, the lead-out section 101 of the wire harness assembly provided in this application includes a lead-out part 1011 and an abutting part 1012, and the abutting part 1012 is connected to the shielding layer 120 through the lead-out part 1011. The main wire 110 passes through the lead-out part 1011, and the abutting part 1012 abuts against the connecting wire 200.

[0065] Specifically, as Figure 1 shown, holes or grooves are formed in the lead-out part 1011, so that the main wire 110 can pass through the holes or grooves in the lead-out part 1011, abut against the connecting wire 200 through the abutting part 1012, and be connected through the first connecting piece 300, making the structure more compact.

[0066] Furthermore, in the wire harness assembly provided in this embodiment, the lead-out part 1011 is bent towards the direction close to the insulating layer 130. Specifically, asFigure 1 As shown, the lead-out portion 1011 is bent in a direction approaching the insulating layer 130 on the shielding wire 100.

[0067] In this way, the tensile strength at the connection line 200, the abutting portion 1012, and the first connecting member 300 can be improved, and it is not easily broken.

[0068] Furthermore, in the wire harness assembly provided in this embodiment, the first connecting member 300 has opposite first pressing portions 310 and second pressing portions 320, and the first pressing portions 310 and the second pressing portions 320 jointly press the abutting portion 1012 and the connection line 200.

[0069] Exemplarily, as Figure 4 shown, the first connecting member 300 is generally a cylindrical cavity structure, and an opening groove is formed in the axial direction thereof. The two sides of the opening groove are respectively the first pressing portion 310 and the second pressing portion 320. After partially abutting the abutting portion 1012 and the partial connection line 200, they are jointly inserted into the cavity of the first connecting member 300, and then the first pressing portion 310 and the second pressing portion 320 are simultaneously pressed by a tool, so that the first pressing portion 310 and the second pressing portion 320 approach each other, thereby jointly pressing the abutting portion 1012 and the connection line 200.

[0070] Of course, the first connecting member 300 can also be replaced by other types of crimping members. The specific type, quantity, etc. of the first connecting member 300 can be determined according to actual installation requirements, and are not specifically limited in this embodiment.

[0071] Furthermore, in the wire harness assembly provided in this embodiment, the lead-out portion 1011 and the abutting portion 1012 are integrally formed with the shielding layer 120.

[0072] Specifically, the lead-out portion 1011 and the abutting portion 1012 can be peeled off from the shielding wire 100, so that the lead-out portion 1011 and the abutting portion 1012 and the shielding layer 120 are of an integral structure, ensuring the stability of the connection and not being easily broken.

[0073] Optionally, in the wire harness assembly provided in this embodiment, the shielding layer 120 includes an aluminum foil layer 121 and a metal mesh layer 122. The aluminum foil layer 121 is disposed outside the main wire 110. The metal mesh layer 122 is disposed outside the aluminum foil layer 121. Specifically, as Figure 1 shown, the aluminum foil layer 121 is used to shield high-frequency electromagnetic waves, and the metal mesh layer 122 is used to shield low-frequency electromagnetic waves, playing a dual shielding role for the main wire 110.

[0074] Exemplarily, as Figure 1As shown, the lead-out section 101 is located on the metal mesh layer 122. At this time, a part of the aluminum foil layer 121 that is the same length as the lead-out section 101 can be cut off to avoid interfering with the sealing of the first protective member 400. Of course, not shown in the figure, the lead-out section 101 can also be located on the aluminum foil layer 121 and the metal mesh layer 122. At this time, only an opening for the main line 110 to pass through needs to be left on the aluminum foil layer 121. The specific length of the lead-out section 101 can be determined according to actual needs and is not overly limited in this embodiment.

[0075] In order to achieve fast and effective sealing at the joint, in this embodiment, the first protective member 400 is a heat-shrinkable tube. Exemplarily, as Figure 1 shown, a section of heat-shrinkable tube is sleeved on the exposed section, the first connector 300, a part of the main line 110, a part of the insulating layer 130, and a part of the connecting line 200, and then this part of the heat-shrinkable tube can be heat-shrunk and sealed by tools such as a hot air gun, at least covering the exposed metal part at the joint. The operation is simple and the installation is convenient.

[0076] Among them, the heat-shrinkable tube can be a double-layer heat-shrinkable tube, making the sealing performance better. The specific model of the heat-shrinkable tube and the like can be determined according to actual needs and are not specifically limited in this embodiment.

[0077] Optionally, in the wire harness assembly provided in this embodiment, the main line 110 is a twisted pair. In this way, stable interaction is facilitated. Among them, the main line 110 can also be set as multiple groups of twisted pairs to transmit a larger amount of data. The specific number, model, etc. of the twisted pairs can be determined according to actual needs and are not specifically limited in this embodiment.

[0078] In a second aspect, an embodiment of the present invention further provides a vehicle, including a vehicle body, and the wire harness assembly provided in any of the above embodiments is disposed on the vehicle body.

[0079] Among them, the wire harness assembly has been described in detail in the above embodiments and will not be elaborated here one by one.

[0080] It can be understood that the wire harness assembly can be connected between electrical components of the vehicle for interaction and grounding.

[0081] The vehicle provided by the embodiment of the present utility model is equipped with a wiring harness assembly, including a shielded wire 100, a connecting wire 200, a first connector 300, and a first protective member 400. Among them, the shielded wire 100 includes a main wire 110, a shielding layer 120, and an insulating layer 130 arranged in sequence from the inside to the outside. By providing a lead-out section 101 on the exposed section of the shielding layer 120, the lead-out section 101 is connected to the connecting wire 200 through the first connector 300 and is bridged through the connecting wire 200. The first protective member 400 is wrapped around the end of the shielded wire 100 to seal the exposed section and the first connector 300, and at least seal the exposed metal parts on the shielding layer 120, the connecting wire 200, and the first connector 300, playing a role in dust prevention and waterproofing. Part of the main wire 110 is located outside the first protective member 400 and is electrically connected to an electrical component for interaction. Part of the connecting wire 200 is located outside the first protective member 400 and is used for grounding or common line connection or connection to the grounding end of an electrical component. That is, through the bridging of the connecting wire 200, only the local connection between the connecting wire 200 and the shielding layer 120 needs to be sealed, and it is easy to achieve a tight seal, thereby improving the protection reliability of the shielded wiring harness.

[0082] Further, in the vehicle provided by this embodiment, a plug-in connector 500 is also provided on the vehicle body. The plug-in connector 500 includes a plurality of plug-in terminals 510 and a second protective member 520 sleeved on the plug-in terminals 510. One end of the main wire 110 and the connecting wire 200 away from the lead-out section 101 is inserted into the second protective member 520 and is respectively connected to the corresponding plug-in terminals 510.

[0083] Specifically, as Figure 3 shown, the plug-in terminals 510 are used to achieve plugging between the main wire 110 or the connecting wire 200 among electrical components. They can be in the structures of plates, sheets, columns, etc., as long as the main wire 110 or the connecting wire 200 can be electrically connected to the plug-in terminals 510. The number of plug-in terminals 510 corresponds one-to-one to the number of the main wire 110 and the connecting wire 200.

[0084] In addition, the second protective member 520 is mainly used to protect the connection between the plug-in terminals 510 and the main wire 110 or the connecting wire 200. It can be in the structures of a housing, a sheath, etc. After the main wire 110 and the connecting wire 200 are correspondingly connected to the plug-in terminals 510, they are inserted into the second protective member 520, thereby realizing the protection of the joints between the main wire 110 and the connecting wire 200 and the plug-in terminals 510.

[0085] In this way, the plug-in connection with the electrical component can be realized through the plug-in connector 500, which is convenient for installation. Among them, the main wire 110 interacts with the electrical component through the plug-in terminals 510, and the connecting wire 200 bridges the shielding layer 120 and the grounding end in the electrical component through the plug-in terminals 510.
