For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0038] The directions or positional relationships indicated by terms such as "upper", "lower", "left", "right", "front", "back", "top", "bottom", "inside" and "outside" are based on the directions or positional relationships shown in the accompanying drawings, or are the directions or positional relationships in which the utility model product is usually placed when in use. They are only for the convenience of description and simplified description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the utility model.

[0039] The terms "first", "second", "third" and the like are merely used to distinguish elements of similar nature, and do not indicate or imply relative importance or a particular order.

[0040] The terms "comprises," "comprising," or any other variations thereof, are intended to cover a non-exclusive inclusion of the elements listed and may also include additional elements not expressly listed.

[0041] As attached Figure 2 and attached Figure 3 As shown, the direction along the X-axis of the coordinate system is defined as the first direction, and the direction along the Y-axis is defined as the second direction, wherein the first direction and the second direction are perpendicular. This coordinate system is intended to illustrate the positional relationship and connection relationship of each component, and does not mean that each component can only be set in this orientation.

[0042] As attached Figure 1 As shown, the high-voltage wire harness connection assembly for a vehicle proposed by the utility model comprises a main body 10, the main body 10 comprises a fixing portion 101 and a sealing portion 102, and is combined with an attached Figure 3The fixing portion 101 is used to connect the first wiring harness 20 and the second wiring harness 30, and to electrically connect the first wiring harness 20 and the second wiring harness 30, wherein the materials of the first wiring harness 20 and the second wiring harness 30 are different, and the sealing portion 102 is used to seal the connection between the first wiring harness 20 and the second wiring harness 30 to isolate the connection between the first wiring harness 20 and the second wiring harness 30 from the external environment.

[0043] Combined with Figure 2 and attached Figure 3 The fixing portion 101 includes a support member 11 and a positioning member 12 at least located at one end of the support member 11 in the first direction. The first wiring harness 20 includes a first connecting segment 21, and the second wiring harness 30 includes a second connecting segment 31. The support member 11 is used to contact and electrically connect with the first connecting segment 21 and the second connecting segment 31. The positioning member 12 is used to contact and connect with at least one side of the first connecting segment 21 and / or the second connecting segment 31 in the second direction to achieve rapid positioning of the support member 11, which is beneficial to improving the connection efficiency and connection quality of the support member 11 with the first connecting segment 21 and the second connecting segment 31, and increases the connection area with the first connecting segment 21 and / or the second connecting segment 31, which is beneficial to improving the stability of the connection between the first wiring harness 20 and the second wiring harness 30 and reducing the risk of breakage.

[0044] As attached Figure 2 As shown, the sealing portion 102 includes a kit 13, which is sleeved on the outside of the fixing portion 101. The kit 13 completely covers the outside of the fixing portion 101 in at least the first direction to isolate the fixing portion 101 from the external environment. The kit 13 enables the fixing portion 101 to seal and connect the first wiring harness 20 and the second wiring harness 30, and can play a role in sealing, waterproofing, and dustproofing. The kit 13 can support the fixing portion 101, increase the structural strength of the fixing portion 101, and is beneficial to improving the stability of the connection between the fixing portion 101 and the first wiring harness 20 and the second wiring harness 30.

[0045] In one example, the length dimension of the support member 11 in the first direction is greater than or equal to the sum of the lengths of the first connecting segment 21 and the second connecting segment 31 in the first direction. Such a configuration enables the support member 11 to have a larger contact area with the first connecting segment 21 and the second connecting segment 31, which is beneficial to improving the connection strength of the support member 11 to ensure that the connection between the first wiring harness 20 and the second wiring harness 30 is firm and not easy to break.

[0046] In one example, as shown in the attached Figure 2As shown, a functional layer 111 is provided on the side of the support member 11 that contacts the first connecting section 21 and / or the second connecting section 31. When the support member 11 is connected to the first connecting section 21 and / or the second connecting section 31, the functional layer 111 is deformed by force, so that the functional layer 111 can fit tightly and firmly with the first connecting section 21 and / or the second connecting section 31, which is beneficial to increase the stability of the connection.

[0047] Optionally, the support member 11 is a sheet-type copper terminal.

[0048] In one example, the first wire harness 20 is a copper wire harness with an end surface area of ​​35 mm 2 The axial length is 1.08m, and the second wiring harness 30 is made of aluminum wiring harness, and its end surface area is 50mm 2 , the axial length is 1.95 m. Optionally, the first wire harness 20 is a non-shielded copper alloy wire harness, and the second wire harness 30 is a non-shielded aluminum alloy wire harness.

[0049] Copper wiring harnesses have good electrical conductivity and mechanical strength, and are the best choice for vehicle high-voltage wiring harnesses. However, they are dense and expensive. Although the electrical conductivity of aluminum wiring harnesses is inferior to that of copper wiring harnesses, they have the advantages of lower density, lower cost and better stability, and can meet the needs of lightweight design of vehicle wiring harnesses. However, aluminum wiring harnesses have poor mechanical strength. If aluminum wiring harnesses are used for high-voltage wiring harnesses connected to dynamic vibrating parts such as motors, the stability of the high-voltage wiring harnesses will be poor, and in severe cases, there will be a risk of breakage, affecting driving safety. The cooperation of the support member 11 and the positioning member 12 can increase the stability of the connection, and the kit 13 can enhance the structural strength of the fixing portion 101, which can effectively reduce the risk of breakage.

[0050] Optionally, the support member 11 and the first connecting section 21 are connected by ultrasonic welding.

[0051] Optionally, the support member 11 and the second connecting section 31 are connected by ultrasonic welding.

[0052] Optionally, the functional layer 111 includes at least a sawtooth that cooperates with the second wiring harness 30. When the second wiring harness 30 is an aluminum wiring harness, since aluminum is easily oxidized, an oxide layer will be formed on the surface. The oxide layer will affect the conductivity of the aluminum wiring harness. The sawtooth of the functional layer 111 can pierce the oxide layer on the surface of the second wiring harness 30, so that the electrical connection between the fixing part 101 and the second wiring harness 30 is more stable and the conductor performance is better.

[0053] In one embodiment, as shown in the attached Figure 4As shown, the positioning member 12 includes first contact members 121 located at both ends of the support member 11 in the first direction, and the two first contact members 121 are located on the same side of the support member 11 in the second direction, and are used to contact and connect with one side of the first connecting section 21 and the second connecting section 31 in the second direction. In this way, the first contact members 121 can position the support member 11 in the second direction, so that the support member 11 can be quickly and accurately connected with the first connecting section 21 and the second connecting section 31. Optionally, the first contact members 121 are welded to the first connecting section 21 and the second connecting section 31.

[0054] Optionally, the first contact member 121 and the support member 11 are integrally formed.

[0055] Optionally, the functional layer 111 is disposed on a side of the first contact member 121 close to the first connecting section 21 and the second connecting section 31 .

[0056] In one example, as shown in the attached Figure 5 As shown, a pressing piece 1211 is protruded from one end of at least one first contact member 121 away from the support member 11, and the pressing piece 1211 is spaced apart from and arranged opposite to the support member 11. The pressing piece 1211 is located on the side of the first connecting section 21 and / or the second connecting section 31 away from the support member 11, that is, at least one of the first connecting section 21 and the second connecting section 31 is clamped between the support member 11 and the pressing piece 1211. The pressing piece 1211 cooperates with the first contact member 121 to position the connection between the support member 11 and the first connecting section 21 and / or the second connecting section 31 in two directions, so as to ensure that the connection position between the support member 11 and the first connecting section 21 and / or the second connecting section 31 is accurate, which is beneficial to improving the connection efficiency.

[0057] Optionally, at least one of the first contact piece 121 and the pressing piece 1211 is provided with the above-mentioned functional layer 111 at one end close to the first connecting section 21 and / or the second connecting section 31. The setting of the functional layer 111 makes the spacing between the pressing piece 1211 and the support piece 11 slightly smaller than the thickness of the first connecting section 21 and / or the second connecting section 31, so as to achieve crimping with the first connecting section 21 and / or the second connecting section 31, which can increase the accuracy and firmness of positioning and connection, thereby solving the problem that the connection between the first wiring harness 20 and the second wiring harness 30 is weak and easy to break during driving, and can also play a role in piercing the oxide layer on the surface of the second connecting section 31 to improve the conductivity.

[0058] Optionally, two first contact members 121 located at both ends of the support member 11 in the first direction are both provided with pressing members 1211 , that is, the number of the pressing members 1211 is the same as the number of the first contact members 121 , so as to have a good positioning effect.

One of the first contact member 121 and the second contact member 122 is used to contact and connect with the first connecting section 21, and the other is used to contact and connect with the second connecting section 31. The first contact member 121 and the second contact member 122 cooperate to limit the first connecting section 21 and the second connecting section 31 in the second direction, so as to prevent the support member 11 from shifting in the second direction during the connection process with the first connecting section 21 and the second connecting section 31, which is conducive to improving the connection efficiency. Optionally, one of the first contact member 121 and the second contact member 122 is welded to the first connecting section 21, and the other is welded to the second connecting section 31.

[0060] Optionally, the first contact member 121 and the second contact member 122 are integrally formed with the support member 11 .

[0061] In one example, as shown in the attached Figure 6 As shown, at least one of the first contact member 121 and the second contact member 122 is provided with a pressing piece 1211 at the end away from the support member 11, and the pressing piece 1211 is spaced apart from and arranged opposite to the support member 11. The pressing piece 1211 is located on the side of the first connecting section 21 and / or the second connecting section 31 away from the support member 11, that is, at least one of the first connecting section 21 and the second connecting section 31 is clamped between the support member 11 and the pressing piece 1211, and the pressing piece 1211 cooperates with the first contact member 121 and / or the second contact member 122 to position the connection between the support member 11 and the first connecting section 21 and / or the second connecting section 31 in two directions, so as to ensure that the connection position between the support member 11 and the first connecting section 21 and / or the second connecting section 31 is accurate, which is beneficial to improving the connection efficiency.

[0062] Optionally, at least one of the first contact piece 121, the second contact piece 122 and the pressing piece 1211 is provided with the above-mentioned functional layer 111 at one end close to the first connecting section 21 and / or the second connecting section 31. The setting of the functional layer 111 makes the spacing between the pressing piece 1211 and the support piece 11 smaller than the thickness of the first connecting section 21 and / or the second connecting section 31, so as to achieve crimping with the first connecting section 21 and / or the second connecting section 31, which can increase the accuracy and firmness of positioning and connection, thereby solving the problem that the connection between the first wiring harness 20 and the second wiring harness 30 is weak and easy to break during driving, and can play a role in piercing the oxide layer on the surface of the second connecting section 31, thereby improving the conductivity.

[0063] In yet another embodiment, as shown in the attached Figure 3As shown, the positioning member 12 includes two first contact members 121 located at both ends of the first direction of the support member 11, and two second contact members 122 located at both ends of the first direction of the support member 11. The first contact members 121 and the second contact members 122 are relatively distributed on both sides of the support member 11 along the second direction. Such an arrangement can increase the stability and firmness of the connection between the first wiring harness 20 and the second wiring harness 30.

[0064] In one example, at least one of the first contact member 121 and the second contact member 122 is provided with a pressing member 1211 protruding from an end away from the support member 11 , and the pressing member 1211 can increase the stability and firmness of the connection between the first wire harness 20 and the second wire harness 30 .

[0065] Optionally, at least one of the first contact member 121 , the second contact member 122 and the pressing member 1211 is provided with the above-mentioned functional layer 111 at one end close to the first connecting section 21 and / or the second connecting section 31 .

[0066] In one example, as shown in the attached Figure 2 As shown, the kit 13 includes a sleeve hole 130 , and the kit 13 uses a double-wall heat shrink tube, which is sleeved on the outside of the fixing part 101 through the sleeve hole 130 . In another example, the kit 13 uses PVC (Polyvinylchloride) tape, which is wrapped around the outside of the fixing part 101 .

[0068] Optionally, the outer diameter of the first sleeve 131 is smaller than the outer diameter of the second sleeve 132.

[0078] Based on the above-mentioned vehicle high-voltage wiring harness connection assembly, as shown in the attached Fig. 9 As shown, the utility model also proposes a high-voltage wire harness assembly for a vehicle, comprising at least one first wire harness 20, at least one second wire harness 30, and a main body 10 for connecting the first wire harness 20 and the second wire harness 30. The first wire harness 20 and the second wire harness 30 are made of different materials. The main body 10 electrically connects the first wire harness 20 and the second wire harness 30. Figure 3 The first wiring harness 20 includes a first connecting section 21, and the second wiring harness 30 includes a second connecting section 31. The above-mentioned support member 11 is used to contact and connect with the first connecting section 21 and the second connecting section 31. The above-mentioned positioning member 12 is used to contact and connect with at least one side of the first connecting section 21 and / or the second connecting section 31 in the second direction. The above-mentioned sealing portion 102 includes a kit 13 that at least covers the outside of the fixing portion 101, so that the first wiring harness 20 and the second wiring harness 30 are sealed and connected, which can meet the vibration, waterproof and other performance requirements of the vehicle wiring harness.

[0079] In one example, when there are two or more first wire harnesses 20, the first wire harnesses 20 are arranged in parallel, and when there are two or more second wire harnesses 30, the second wire harnesses 30 are arranged in parallel. Such an arrangement can increase the current carrying capacity of the wire harnesses.

[0080] In one example, the first wire harness 20 is a copper wire harness with an end surface area of ​​35 mm 2The axial length is 1.08m, and the second wiring harness 30 is made of aluminum wiring harness, and its end surface area is 50mm 2 , the axial length is 1.95 m. Optionally, the first wire harness 20 is a non-shielded copper alloy wire harness, and the second wire harness 30 is a non-shielded aluminum alloy wire harness.

[0081] As attached Fig. 9 As shown, one end of the first wire harness 20 away from the main body 10 is connected to the high voltage connector 40 , and one end of the second wire harness 30 away from the main body 10 is connected to the DC charging socket 50 .

[0082] Optionally, the high voltage connector 40 includes a round terminal which is crimped to the first wire harness 20 .

[0083] Optionally, the DC charging socket 50 includes a sheet-type copper terminal, and the sheet-type copper terminal is connected to the second wire harness 30 by ultrasonic welding.

[0084] In one example, a plurality of the above-mentioned reinforcements 16 are sleeved on the outside of the first wiring harness 20 and / or the second wiring harness 30. The reinforcements 16 are used to fix and gather the first wiring harness 20 and / or the second wiring harness 30 so as to adjust the direction and position of the wiring harness as needed. This can meet the spatial layout requirements of the wiring harness, and is helpful in avoiding surrounding parts so that the wiring harness does not interfere with surrounding parts, which is helpful in improving the reliability of the wiring harness. The aperture of the connecting hole 161 can be adjusted according to the outer diameter of the first wiring harness 20 and the second wiring harness 30, and the wiring harness has good applicability.

[0085] When the same current is conducted, the weight of the aluminum wiring harness is only one-third of that of the copper wiring harness, which is beneficial to reducing the weight and cost of the vehicle wiring harness. During the operation of the vehicle, due to the high-speed operation of the motor, the high-voltage connector 40 and the DC charging socket 50 vibrate to varying degrees with the vehicle, causing the wiring harness to vibrate accordingly. By setting the fixing portion 101, the firmness of the wiring harness connection can be increased, and the risk of breakage at the connection between the first wiring harness 20 and the second wiring harness 30 during driving is reduced. Since the high-voltage connector 40 is close to the motor and the vibration is more severe, a copper wiring harness is arranged on the side of the high-voltage connector 40. Compared with the aluminum wiring harness, the copper wiring harness has better strength and can play a good anti-vibration role, ensuring the stability of the wiring harness, which is beneficial to ensuring the service life of the wiring harness. An aluminum wiring harness is arranged on the side of the DC charging socket 50, and aluminum is used instead of copper, which is beneficial to reducing the overall weight of the wiring harness.

[0086] Therefore, the utility model proposes a better high-voltage wiring harness assembly for a vehicle, in which the first wiring harness 20 is arranged on the side close to the vibration source, and the second wiring harness 30 is arranged on the side away from the vibration source, which can not only ensure the high-strength performance of the wiring harness assembly, but also play a role in reducing weight and cost.

[0087] The beneficial effects of the high-voltage wire harness connection assembly for a vehicle proposed by the utility model are:

[0088] The support member 11 of the fixed portion 101 can contact and electrically connect with the first connecting section 21 and the second connecting section 31, and can play a role in connecting the wire harness in the first direction. The positioning member 12 can play a role in positioning the first connecting section 21 and / or the second connecting section 31 in the second direction, and can achieve rapid positioning of the support member 11, thereby improving the connection efficiency. The positioning member 12 can increase the contact area between the support member 11 and the first connecting section 21 and / or the second connecting section 31, which is beneficial to improving the connection strength. The sealing portion 102 includes a kit 13, which can at least cover the outside of the fixed portion 101, and can support the fixed portion 101 to increase the structural strength of the fixed portion 101, thereby ensuring the stability of the connection, and can ensure that the fixed portion 101 is sealed and connected to the first wire harness 20 and the second wire harness 30, thereby playing a role in waterproofing and dustproofing, thereby ensuring the connection quality of the first wire harness 20 and the second wire harness 30.

[0089] The beneficial effects of the high-voltage wiring harness assembly of a vehicle proposed by the utility model are:

[0090] The connection between the first wiring harness 20 and the second wiring harness 30 is stable and reliable, and the overall weight is reduced, which is conducive to achieving weight reduction and cost reduction, and has good economy and practicality.
