[0046] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

[0047] The present disclosure provides a battery pack high voltage connector assembly, referring to Figure 1 As shown, the battery pack high-voltage connector assembly may include a high-voltage connector 1 and a protective component 2.

[0048] The high voltage connector 1 may include a connector body 11 , a first connector 12 and a second connector 13 , wherein the first connector 12 and the second connector 13 are both connected to the connector body 11 .

[0049] The connector body 11 can be connected to the housing of the battery pack to fix the high-voltage connector 1. The side of the connector body 11 away from the first connector 12 and the second connector 13 can have a corresponding interface, which is used to electrically connect to components such as motors, so as to realize the battery module in the battery pack to power components such as motors. The connector body 11 can have a sealing gasket, which is used to block the path of foreign matter from the external environment passing through the high-voltage connector 1 and entering the battery pack, so as to prevent foreign matter from damaging the internal components of the battery pack.

[0050] Reference Figure 2 As shown, in some embodiments, the first connector 12 has a first through hole 121, a first nut 122 and a first sub-isolator 123. The first through hole 121 is connected to the first connection row 3 of the battery pack through the first nut 122. The first sub-isolator 123 is opposite to the first through hole 121 and is used to accommodate the first nut 122. The second connector 13 has a second through hole 131, a second nut 132 and a second sub-isolator 133. The second through hole 131 is connected to the second connection row 4 of the battery pack through the second nut 132. The second sub-isolator 133 is opposite to the second through hole 131 and is used to accommodate the second nut 132.

[0051] Among them, the first connecting row 3 and the second connecting row 4 are electrically connected to the positive and negative poles of the battery module in the battery pack, respectively, so that the electrical energy in the battery module can be output to the outside through the first connecting member 12 and the second connecting member 13 to supply power to the components connected to the high-voltage connector 1 (for example: motor).

[0052] Reference Figure 1 As shown, the protection assembly 2 may include a protection base 21, an isolating member 22, and a protection cover plate 23. The protection base 21 is located on a side of the first connecting member 12 away from the second connecting member 13, the isolating member 22 is located between the first connecting member 12 and the second connecting member 13, and is connected to the protection base 21, and the protection cover plate 23 is located on a side of the second connecting member 13 away from the first connecting member 12, and is connected to the protection base 21.

[0053] The protective base 21 can prevent other components of the battery pack from contacting the first connector 12 during a vehicle collision or during assembly of the battery pack high-voltage connector assembly, thereby preventing short circuits, heating, or even fire caused by contact between the first connector 12 and other conductive components after power is supplied.

[0054] The protective cover 23 can prevent other components of the battery pack from contacting the second connector 13 during a vehicle collision or during assembly of the battery pack high-voltage connector assembly, thereby preventing short circuits, heating, or even fire caused by contact between the second connector 13 and other conductive components after power is supplied.

[0055] The isolating member 22 can prevent the first connector 12 and the second connector 13 from contacting each other during a vehicle collision or during assembly of the battery pack high-voltage connector assembly, thereby preventing the first connector 12 and the second connector 13 from contacting each other after power is turned on, causing a short circuit, failure of electrical components in subsequent circuits, heat generation, or even fire.

[0056] In some embodiments, the protective base 21, the isolation member 22 and the protective cover plate 23 are all made of plastic material (poly(hexamethylene adipamide) PA66 is used as an example). On the one hand, PA66 has good insulation performance and can effectively prevent the first connector 12, the second connector 13 and the conductor element from short-circuiting. On the other hand, PA66 has high mechanical strength and heat resistance, which can enhance the structural strength of the protective component 2 and extend the service life of the protective component 2.

[0057] The protective base 21, the isolating member 22 and the protective cover plate 23 can all be made of plastic materials, and the present disclosure does not specifically limit the processing technology of the protective base 21, the isolating member 22 and the protective cover plate 23 made of plastic materials. The protective base 21, the isolating member 22 and the protective cover plate 23 can also be made of a mixture of plastic materials and other materials, and can be specifically matched and set according to the use scenarios of different battery pack high-voltage plug assemblies, the life requirements of the protective component 2, the manufacturing cost and other factors.

[0058] Reference Figure 3 As shown, in some embodiments, the protective base 21 has a first receiving groove 211, and the first receiving groove 211 is opposite to the first nut 122. The size and shape of the first receiving groove 211 are adapted to the size and shape of the first sub-isolator 123, and the first receiving groove 211 and the first sub-isolator 123 can limit the freedom of the protective base 21 in the X direction and the Y direction. The plane formed by the X direction and the Y direction is perpendicular to the axis of the first nut 122.

[0059] Reference Figure 3 As shown, in some embodiments, the protective base 21 has a first buckle 212 and a second buckle 213, the first buckle 212 is engaged with the isolation member 22, and the second buckle 213 is engaged with the protective cover plate 23. The first buckle 212 is used to limit the freedom of the protective base 21 and the isolation member 22 in the Z direction, and the second buckle 213 is used to limit the freedom of the protective base 21 and the protective cover plate 23 in the Z direction. The Z direction is perpendicular to the X direction and the Y direction respectively.

[0060] The present disclosure does not specifically limit the number and size of the first buckles 212, which can be set according to the shape, size and other parameters of the spacer 22. The present disclosure does not specifically limit the number and size of the second buckles 213, which can be set according to the shape, size and other parameters of the protective cover 23.

[0061] The first buckle 212 and the second buckle 213 are used to fix the relative positions of the protective base 21, the isolation member 22, and the protective cover plate 23, without the need for bolts, welding, or other connection methods. The installation process is simple and fast, which is conducive to simplifying the assembly process of the protective component 2 and improving the assembly efficiency. At the same time, the buckle can be repeatedly disassembled and assembled, which is convenient for the subsequent maintenance and repair of the battery pack high-voltage plug assembly.

[0062] Reference Figure 4 As shown, in some embodiments, the protective cover plate 23 has a second receiving groove 231, and the second receiving groove 231 is opposite to the second nut 132. The size and shape of the second receiving groove 231 are adapted to the size and shape of the second nut 132, and the second receiving groove 231 and the second nut 132 can limit the freedom of the protective cover plate 23 in the X direction and the Y direction. The plane formed by the X direction and the Y direction is perpendicular to the axis of the second nut 132.

[0063] Reference Figure 5 As shown, in some embodiments, the isolation member 22 has a step structure 221, and the step structure 221 is in contact with the second connecting member 13. The step structure 221 is used to support the second connecting member 13, thereby increasing the structural strength of the second connecting member 13 and preventing the second connecting member 13 from extending too long and causing bending, breaking and other adverse phenomena.

[0064] In some embodiments, the isolating member 22 has a limiting structure 223 . The limiting structure 223 may include two protrusions. The two protrusions are engaged with the second sub-isolating member 133 , thereby limiting the freedom of the isolating member 22 in the X direction.

[0065] Reference Figure 2 As shown, in some embodiments, the first connecting row 3 has a first metal wire 31 and a first insulating shell 32. The first insulating shell 32 is sleeved on the outer wall of the first metal wire 31, and the two ends of the first metal wire 31 are exposed to the outside. The two ends of the first metal wire 31 are respectively connected to the battery module and the first connecting member 12.

[0066] Reference Figure 3 and Figure 4 As shown, the protective base 21 has a first wire groove 214, and the protective cover 23 has a second wire groove 232. The first wire groove 214 and the second wire groove 232 are opposite to each other. The wire space formed between the first wire groove 214 and the second wire groove 232 is used to cover the exposed end of the first metal wire 31 to prevent other conductor elements from contacting the exposed end of the first metal wire 31 and causing a short circuit.

[0067] Reference Figure 2As shown, in some embodiments, the second connecting row 4 has a second metal wire 41 and a second insulating shell 42. The second insulating shell 42 is sleeved on the outer wall of the second metal wire 41 and exposes both ends of the second metal wire 41. The two ends of the second metal wire 41 are respectively connected to the battery module and the second connecting member 13.

[0068] Reference Figure 4 and Figure 5 As shown, the isolating member 22 has a third wire groove 222, and the protective cover plate 23 has a fourth wire groove 233. The third wire groove 222 and the fourth wire groove 233 are opposite to each other. The wire space formed between the third wire groove 222 and the fourth wire groove 233 is used to cover the exposed end of the second metal wire 41 to prevent other conductor elements from contacting the exposed end of the second metal wire 41 and causing a short circuit.

[0069] The wire space formed between the first wire groove 214 and the second wire groove 232 and the wire space formed between the third wire groove 222 and the fourth wire groove 233 avoids direct exposure of metal wires, thereby increasing safety protection during the production, inspection and maintenance of the battery pack system. On the one hand, it avoids the risk of electric shock to operators, and on the other hand, it avoids short circuits caused by metal wires coming into contact with conductive foreign objects.

[0070] Below, the assembly process of the battery pack high-voltage connector assembly is exemplified.

[0071] Step 1: Install the connector body 11 on the battery pack housing through the corresponding mounting holes on the connector body 11.

[0072] Step 2: Reference Figure 6 As shown, the isolating member 22 is inserted between the first connecting member 12 and the second connecting member 13 until the limiting structure 223 on the isolating member 22 is engaged with the second sub-isolating member 133 .

[0073] The snap-fitting fit between the limiting structure 223 and the second sub-isolator 133 ensures a smaller gap between the isolator 22 and the second connecting member 13, thereby avoiding undesirable phenomena such as looseness or abnormal noise caused by a larger gap, and also ensures the moving distance of the isolator 22 in the X direction, making it easier for assemblers to receive feedback on the assembly to the specified position.

[0074] Step 3: Reference Figure 7 As shown, the first receiving groove 211 of the protection base 21 is aligned with the first nut 122 , and the protection base 21 is moved until the first buckle 212 is engaged with the isolation member 22 .

[0075] The matching relationship between the first receiving groove 211 and the first nut 122 ensures the relative position relationship between the protective base 21 and the first connecting member 12 in the X direction and the Y direction. The clamping position of the first buckle 212 ensures the relative position relationship between the protective base 21 and the first connecting member 12 in the Z direction.

[0076] Step 4: Reference Figure 8 (To show the first connecting member 12 and the second connecting member 13, Figure 8 As shown in the figure (the protective base 21 , the isolating member 22 , and the protective cover plate 23 are hidden), the first connecting member 12 is connected to the first connecting row 3 via the first nut 122 , and the second connecting member 13 is connected to the second connecting row 4 via the second nut 132 .

[0077] The first connection row 3 and the second connection row 4 have a high degree of freedom in installation and can be matched and set according to the positions of the positive and negative poles of the battery module, which is beneficial to the compatibility of the battery pack high-voltage connector assembly with different battery modules.

[0078] Step 5: Reference Fig. 9 As shown, the second receiving groove 231 of the protective cover plate 23 is aligned with the second nut 132 , and the protective cover plate 23 is moved until the second buckle 213 is engaged with the protective cover plate 23 .

[0079] The matching relationship between the second receiving groove 231 and the second nut 132 ensures the relative position relationship between the protective cover 23 and the second connecting member 13 in the X direction and the Y direction. The clamping position of the second buckle 213 ensures the relative position relationship between the protective cover 23 and the protective base 21 in the Z direction.

[0080] Through the operations of step 2, step 3, and step 5, effective constraints on the protection component 2 in the three directions of X, Y, and Z can be achieved, and complex connection methods such as bolts and welding can be avoided to achieve the installation of the protection component 2 at the specified position of the high-voltage connector 1.

[0081] The protection component 2 is made of plastic material, which can effectively prevent the first connector 12 from directly contacting other conductor components, the second connector 13 from directly contacting other conductor components, and the first connector 12 from directly contacting the second connector 13 to avoid short circuit.

[0082] Based on the same concept, an embodiment of the present disclosure also provides a vehicle, which may include a battery pack and the battery pack high-voltage connector assembly in any one of the above embodiments.

[0083] The battery pack has a first connection row 3 and a second connection row 4 . The first connection row 3 is electrically connected to the first connection member 12 , and the second connection row 4 is electrically connected to the second connection member 13 .
