DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments.

[0038] Unless otherwise defined, all technical terms used in the embodiments of the present application have the same meanings as commonly understood by those of ordinary skill in the art.

[0039] In order to make the technical solutions and advantages of the present application more clear, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0040] The automotive wiring harness acts as a neural network in the vehicle, connecting various electrical appliances to realize functions such as power supply, communication and control between electrical appliances. With the rise of new energy vehicles, the number of automotive electrical appliances continues to increase, and the number of wiring harness loops continues to increase, making it increasingly difficult for existing wiring harnesses to adapt to the increasingly complex in-vehicle installation environment, and it is easy to cause short circuit risks, affecting the normal operation of the vehicle.

[0041] In order to solve the above technical problems, the present application provides an automotive wiring harness assembly and an automobile, which can improve the adaptability of the automotive wiring harness assembly to the in-vehicle installation environment while reducing the risk of short circuit.

[0042] like Figure 1 As shown, the automobile wiring harness assembly includes a wiring harness body 1, a first connecting terminal 2, a second connecting terminal 3 and an insulating protective cover 4.

[0043] The first connecting terminal 2 is connected to the first end of the wiring harness body 1, and the second connecting terminal 3 is connected to the second end of the wiring harness body 1. The first connecting terminal 2 and the second connecting terminal 3 both include a connected fixing portion 31 and a transition portion 32. The fixing portion 31 surrounds the outer periphery of the wiring harness body 1, and the transition portion 32 of the first connecting terminal 2 and / or the second connecting terminal 3 is inclined to the length direction of the fixing portion 31.

[0044] The first end and the second end of the wiring harness body 1 are two ends in the extension direction of the wiring harness body 1. Figure 1 The left end of the center wire harness body 1 is a first end, and the right end is a second end.

[0045] like Figure 2 As shown, the fixing portion 31 is at least partially arc-shaped and can be semi-wrapped around the outer circumference of the wiring harness body 1. Two crimping wings 33 are provided at one end of the fixing portion 31 away from the adapter portion 32. The two crimping wings 33 are arranged opposite to each other in a direction perpendicular to the length direction of the fixing portion 31. The two crimping wings 33 are respectively used for crimping with the insulation skin and the core wire of the wiring harness body 1.

[0046] It can be understood that crimping is the process of forcing the wire to the contact surface of the terminal by external force. Specifically, crimping is achieved by the upper and lower blades of the crimping die relying on the force of the crimping machine. In fact, it is the process of the terminal from free bending to correct bending. This connection method does not require welding materials, is suitable for mass production, and has reliable connection and long life.

[0047] The transition portion 32 is in a plate or sheet shape. For example, in the first connection terminal 2, the extension plane of the transition portion 32 is parallel to the length direction of the fixing portion 31; Figure 2 As shown, in the second connecting terminal 3 , the extension plane of the transition portion 32 is inclined to the length direction of the fixing portion 31 .

[0048] The angle between the adapter portion 32 and the fixing portion 31 in the length direction can be set according to actual needs. For example, the angle between the adapter portion 32 and the fixing portion 31 in the length direction is 120°.

[0049] The adapter 32 is used to connect with automobile accessories, such as Figure 2 As shown, the adapter part 32 is provided with a first through hole 321 , which penetrates the adapter part 32 along the thickness direction of the adapter part 32 , and is used to allow threaded fasteners to pass through, so as to connect the automotive accessory to the adapter part 32 using the threaded fasteners.

[0050] There are many parts inside the car and the space is relatively small. By arranging the adapter portion 32 in an inclined direction relative to the length direction of the fixing portion 31, the first connecting terminal 2 and / or the second connecting terminal 3 can be adapted to the installation environment inside the car. Figure 3 As shown, there is a certain angle and distance between the fixing portion 31 and the automobile accessory (ie, the DC / DC converter 100 ), which can prevent the wiring harness body 1 from being damaged or even broken due to excessive bending, thereby improving the stability of the wiring harness body 1 .

[0051] The insulating protective cover 4 is sleeved on the end of the wiring harness body 1 , and the insulating protective cover 4 is located adjacent to the first connecting terminal 2 and / or the second connecting terminal 3 .

[0052] The number of the insulating protective sleeves 4 can be one or more. Exemplarily, there are two insulating protective sleeves 4, and the insulating protective sleeves 4 are arranged on the adjacent sides of the first connection terminal 2 and the second connection terminal 3; or, there is one insulating protective sleeve 4, as Figure 1 shown, the insulating protective sleeve 4 is arranged on the adjacent side of the second connection terminal 3.

[0053] The insulating protective sleeve 4 is made of insulating material. By sleeving the insulating protective sleeve 4 on the end of the wire harness body 1, the probability of short circuit of the first connection terminal 2 and / or the second connection terminal 3 due to contacting metal during repair or electric drive operation is reduced, and certain protection ability is provided to reduce the probability of liquid splashing onto the first connection terminal 2 and / or the second connection terminal 3.

[0054] Exemplarily, the first connection terminal 2 is used to connect with the electrical box of the vehicle, the second connection terminal 3 is used to connect with the DC / DC converter 100 of the vehicle, and the wire harness body 1 is the low-voltage positive wire harness of the DC / DC converter 100.

[0055] In the related art, the DC / DC converter 100 is often integrated in the CDU (Conversion & Distribution Unit, three-in-one integrated vehicle-mounted charging and power distribution assembly) or the multi-in-one motor. The DC / DC converter 100 is mainly used for the conversion of high-voltage direct current of the battery pack to low-voltage direct current. The DC / DC converter 100 is connected to the electrical box through a low-voltage wire harness to realize the power supply of the low-voltage battery and the low-voltage electrical appliances of the whole vehicle. The low-voltage wire harness part of the DC / DC converter 100 includes positive and negative wire harnesses. The positive wire harness bears low-voltage large current, and the negative wire harness is mainly used for module grounding to keep the module at "0" potential. The DC / DC converter 100 is usually arranged outside the cabin, while the electrical box is located inside the cabin. The local part of the positive wire harness is located outside the cabin, suffering from harsh environment, needing to withstand high temperature, and at the same time there are risks such as wading, salt spray, and corrosion, which are prone to failure or damage, affecting the normal use of the vehicle.

[0056] By arranging the insulating protective sleeve 4 on the adjacent side of the second connection terminal 3, it plays a certain protective role for the second connection terminal 3 and a part of the wire harness body 1 located in the harsh environment, and improves the rust prevention, corrosion prevention and salt spray resistance performance of the second connection terminal 3 and the local wire harness body 1.

[0057] Exemplarily, the wire harness body 1 is a FLRY wire. The FLRY wire adopts a polyvinyl chloride insulated single-core symmetrical conductor structure, which is suitable for electrical equipment in high-temperature environments. Its conductor is stranded by bare copper wires or tinned copper wires, has a multi-strand stranded structure, and has good thermal stability and mechanical properties, and can resist acid and alkali, oil resistance, moisture resistance, etc.

[0058] Alternatively, the wiring harness body 1 is a FL2G heat-resistant wire, which is a silicone insulated cable for automobiles, suitable for low-voltage cables for road vehicles, and has the characteristics of high temperature resistance, low temperature resistance, oil resistance, and corrosion resistance.

[0059] Exemplarily, the first connection terminal 2 and / or the second connection terminal 3 are provided with a metal coating, such as a matte tin coating, which can improve the wear resistance, conductivity, reflectivity and corrosion resistance of the first connection terminal 2 and / or the second connection terminal 3 and improve the appearance of the parts. The thickness of the metal coating can be 3μm to 7μm, for example, the thickness of the metal coating is 5μm, which improves the rust, corrosion and salt spray resistance of the first connection terminal 2 and / or the second connection terminal 3.

[0060] Exemplarily, the board-end connector of the DC / DC converter 100 is connected to the second connection terminal 3 using an OT terminal, which has the advantages of stable connection, easy installation, high conductivity, good corrosion resistance, etc.

[0061] Optionally, the OT terminal and the second connection terminal 3 are fastened by M6 screws, and the fastening torque is 15±1N.

[0062] Optionally, the first connecting terminal 2 is connected to the electrical box using M8 screws, with a tightening torque of 13±2N.

[0063] The automotive wiring harness assembly provided in the embodiment of the present application is configured such that the adapter portion 32 of the first connecting terminal 2 and / or the second connecting terminal 3 is inclined to the length direction of the fixing portion 31, so that a certain angle is provided between the adapter portion 32 and the fixing portion 31. While being adapted and connected to the automotive accessories through the adapter portion 32, a certain distance is provided between the fixing portion 31 and the automotive accessories, thereby avoiding interference between the first connecting terminal 2 and / or the second connecting terminal 3 and the automotive accessories. This not only enables the first connecting terminal 2 and / or the second connecting terminal 3 to be suitable for different in-vehicle installation environments, but also reduces the risk of short circuit of the first connecting terminal 2 and / or the second connecting terminal 3 due to squeezing or contacting the automotive accessories. By providing an insulating protective cover 4, insulation protection is provided for the wiring harness body 1 and the first connecting terminal 2 / the second connecting terminal 3, thereby reducing the probability of liquid splashing onto the first connecting terminal 2 and / or the second connecting terminal 3, further reducing the risk of short circuit, and improving the safety performance of the automotive wiring harness assembly and the automobile.

[0064] In a further embodiment, the insulating protective cover 4 is made of a flexible material with elastic deformation capability.

[0065] Exemplarily, the insulating protective sleeve 4 is made of materials such as rubber and plastic, and specifically may be EPDM rubber.

[0066] By setting the insulating protective cover 4 to be made of a flexible material with elastic deformation ability, it not only has good chemical corrosion resistance, insulation performance, waterproof properties and other characteristics, but also has good elasticity and flexibility, and can fit tightly to the wiring harness body 1 and the first connecting terminal 2 / second connecting terminal 3 to provide effective protection.

[0067] In a further embodiment, the insulating protective cover 4 includes a main body 41 and a cover 42 connected to each other. The main body 41 is sleeved on the outer periphery of the wiring harness body 1 and has an interference fit with the wiring harness body 1 , and the cover 42 covers the first connecting terminal 2 and / or the second connecting terminal 3 .

[0068] like Figure 4 As shown, the main body 41 is substantially tubular and is used to be sleeved on the wire harness body 1 , and the cover 42 is located at one end of the main body 41 in the length direction.

[0069] By providing interference fit between the main body 41 and the wire harness body 1 , the connection firmness and stability between the main body 41 and the wire harness body 1 are ensured.

[0070] like Figure 4 As shown, the cover body portion 42 is a cover-like structure with an opening at the bottom, and the cover body portion 42 is used to cover the first connecting terminal 2 and / or the second connecting terminal 3, thereby providing shielding and protection for the first connecting terminal 2 and / or the second connecting terminal 3 to prevent liquid from splashing onto the first connecting terminal 2 and / or the second connecting terminal 3.

[0071] Since the insulating protective cover 4 is made of a flexible material with elastic deformation capability, the cover portion 42 and the main body portion 41 can move relative to each other. The operator can lift up the cover portion 42 to expose the first connecting terminal 2 and / or the second connecting terminal 3, thereby facilitating the connection of the first connecting terminal 2 / the second connecting terminal 3 with automotive accessories and completing the installation of the automotive wiring harness assembly.

[0072] Furthermore, a boss portion 43 is protruded from the outer wall of the cover portion 42 .

[0073] like Figure 4 As shown, the boss portion 43 is in a strip or block shape, and the boss portion 43 is convex relative to the top surface of the outer wall of the cover body portion 42 .

[0074] By providing the boss portion 43, it is convenient for the operator to grasp the boss portion 43 and lift up the cover portion 42, thereby exposing the first connection terminal 2 and / or the second connection terminal 3, making it convenient to connect the first connection terminal 2 / the second connection terminal 3 to the automotive accessories and complete the installation of the automotive wiring harness assembly.

[0075] In a further embodiment, the automobile wiring harness assembly further includes a sealing member 5 , which is sleeved on the outer periphery of the wiring harness body 1 and is sealed and connected to the wiring harness body 1 .

[0076] Specifically, the wire harness body 1 is divided into an indoor section and an outdoor section, and the seal 5 is installed between the indoor section and the outdoor section of the wire harness body 1, that is, the seal 5 is located in the wet-dry transition area of the wire harness body 1.

[0077] By arranging the seal 5 in the wet-dry transition area of the wire harness body 1, the wet-dry separation of the automotive wire harness assembly is realized, the sealing performance of the automotive wire harness assembly in the wet-dry transition area is improved, the wire harness body 1 is prevented from short-circuiting and other failures due to water ingress, and the waterproof performance of the automotive wire harness assembly is improved.

[0078] The seal 5 is connected to the automotive parts, so that the automotive wire harness assembly passes through the automotive parts, with a part located indoors and another part located outdoors. Protecting the wire harness body 1 with the seal 5 helps to improve the wear resistance of the automotive wire harness assembly. Exemplarily, the seal 5 is connected to the automotive storage box, and the automotive wire harness assembly passes through the automotive storage box.

[0079] Optionally, the seal 5 and the wire harness body 1 are hermetically connected by means such as glue sealing, O-ring sealing, and clamp sealing.

[0080] In a specific embodiment, the seal 5 includes an interference-fit connecting member 51 and a skeleton 52. The skeleton 52 is sleeved on the outer periphery of the wire harness body 1, and the connecting member 51 is provided with a plurality of elastic buckles 511, and the elastic buckles 511 are adapted to be clamped with the automotive parts.

[0081] As Figure 5 shown, the skeleton 52 includes a tubular structure 521 and a disc-shaped structure 522. The wire harness body 1 passes through the tubular structure 521, and the disc-shaped structure 522 is disposed around the outer periphery of the tubular structure 521.

[0082] Specifically, the connecting member 51 encloses the periphery of the tubular structure 521 and is in interference fit with the disc-shaped structure 522 to realize the connection between the connecting member 51 and the skeleton 52.

[0083] As Figure 5 shown, the connecting member 51 is provided with elastic buckles 511. Correspondingly, automotive parts such as the automotive storage box are provided with slots for cooperating with the elastic buckles 511. When the elastic buckles 511 are cooperatively connected with the slots, the elastic buckles 511 rebound and collide with the automotive parts, so as to prompt the operator to complete the connection between the seal 5 and the automotive parts.

[0084] Among them, the disc-shaped structure 522 is also used for clamping with the automotive parts to play a role in fixing the wire harness.

[0085] Optionally, the seal 5 is a rubber part, which has the advantages of high elasticity, corrosion resistance, good insulation performance, good sealing performance, etc.

[0086] In a further embodiment, a waterproof material is filled between the main body portion 41 and the wire harness body 1; and / or, a waterproof material is filled between the skeleton 52 and the wire harness body 1.

[0087] The waterproof material can be anti-cement, polyurethane sealant, silicone sealant, epoxy resin sealant, etc., and the present application does not make specific limitations.

[0088] By filling the waterproof material, the gaps between the wire harness body 1 and the main body portion 41 / skeleton 52 are further filled, preventing moisture, dust or other pollutants from entering, and improving the sealing effect.

[0089] In one embodiment, the automotive wire harness assembly further includes a wire harness bracket 6 connected to the wire harness body 1. The wire harness bracket 6 is provided with a plurality of tie holes 61 for allowing tie straps to pass through.

[0090] The wire harness bracket 6 is used to restrict the routing of the wire harness body 1, so that a certain distance is maintained between the wire harness body 1 and automotive accessories. For example, a gap of 200 mm is maintained between the wire harness body 1 and the cross beam.

[0091] As Figure 6 shown, the wire harness bracket 6 is provided with a second through hole 62, a third through hole 63, a fourth through hole 64 and tie holes 61. Among them, there are two tie straps, and the second through hole 62, the third through hole 63 and the fourth through hole 64 are all one.

[0092] Among them, the second through hole 62 is used to provide a fixing point for automotive accessories, such as providing a fixing point for the rear motor wire harness.

[0093] The third through hole 63 is used to allow fasteners to pass through, thereby connecting the wire harness bracket 6 and the wire harness body 1. For example, the third through hole 63 is used to allow kidney-shaped staples to pass through, and the wire harness bracket 6 and the wire harness body 1 are fixedly connected by kidney-shaped staples.

[0094] The fourth through hole 64 is used to provide a connection position between the wire harness bracket 6 and automotive accessories, such as providing a position for threaded fastening connection between the wire harness bracket 6 and the motor. Optionally, the wire harness bracket 6 and the motor are connected by an M8 screw, and the tightening torque is 20 ± 3 N.

[0095] The tie holes 61 are used to allow tie straps to pass through, facilitating the use of tie straps to control the routing of the wire harness body 1 and avoiding damage to the wire harness body 1 due to vibration, displacement or interference with other components.

[0096] Optionally, the wire harness bracket 6 is made of a metal material and has high strength. For example, the wire harness bracket 6 is an electrophoretic iron part. The electrophoretic treatment forms a sealed coating on the surface of the iron workpiece, which can effectively prevent the metal part from rusting. Especially in harsh environmental conditions such as seawater, oil stains, and acid rain, the anti-corrosion effect of the coating is more significant. Moreover, after the electrophoretic treatment, a high-hardness coating will be formed on the surface of the workpiece, which can effectively prevent the surface of the workpiece from being scratched, worn, and damaged, thereby increasing its service life.

[0097] By providing the wire harness bracket 6, a connection position is provided for the wire harness body 1 and other automotive accessories, improving the stability of the wire harness body 1, facilitating the control of the routing of the wire harness body 1, realizing the layout of the wire harness body 1 in a narrow space, avoiding damage to the wire harness body 1 due to vibration, displacement, or interference with other components, and preventing the wire harness body 1 from being squeezed or worn through due to lack of fixation.

[0098] In one embodiment, the automotive wire harness assembly further includes a thermal insulation layer 7, and the thermal insulation layer 7 wraps at least a part of the wire harness body 1.

[0099] Exemplarily, the thermal insulation layer 7 is made of metal. For example, the thermal insulation layer 7 is an aluminum foil.

[0100] By wrapping the thermal insulation layer 7 around at least a part of the wire harness body 1, the temperature resistance of the wire harness body 1 is improved, and the temperature resistance can be increased by about 10°C - 20°C, which is beneficial to improving the stability of the automotive wire harness assembly and increasing the service life of the automotive wire harness assembly.

[0101] The embodiment of the present application also provides an automobile, which includes the automotive wire harness assembly provided in any of the above embodiments.

[0102] In the present application, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance. The term "plurality" refers to two or more, unless otherwise clearly defined.
