The electric connector comprises a mounting seat, a plurality of high-voltage poles and a plurality of first mounting pieces. The high-voltage poles are mounted on the mounting seat through the first mounting pieces, and at least one high-voltage pole is arranged on each first mounting piece. Compared with using an integral mounting piece to mount all the poles, the scheme of mounting the poles by the plurality of first mounting pieces can effectively avoid the fracture of the first mounting pieces, thereby further ensuring the mounting stability of the high-voltage poles, and further ensuring the smooth electrical connection between the battery pack and the electric vehicle, and improving the driving stability of the electric vehicle. On the other hand, if an integral first mounting piece is used to mount all the poles, the position of each pole needs to be accurately positioned during the manufacturing of the first mounting piece. The mounting by the plurality of first mounting pieces is beneficial to reducing the production difficulty and reducing the production cost.

Description

Technical Field

[0001] This invention relates to the field of electrical connector technology, and particularly to an electrical connector, an electrical connection assembly, an electric vehicle, and a battery pack. Background Technology

[0002] In recent years, new energy vehicles have developed rapidly. Electric vehicles, which rely on batteries as their driving energy, have the advantages of zero emissions and low noise. As the market share and usage frequency of electric vehicles are increasing, electric commercial vehicles, such as electric heavy-duty trucks and electric light-duty trucks, are also gradually appearing in their respective application scenarios.

[0003] In the prior art, battery packs and electric vehicles are generally connected by electrical connectors. The electrical connectors contain high-voltage terminals. In order to improve the installation stability of the high-voltage terminals, mounting components are generally used to install them. Currently, a single mounting component is usually used to install all the high-voltage terminals. However, such mounting components are large in size, which reduces their strength and makes them prone to breakage. This is not conducive to long-term use, and the installation position of each terminal on the mounting component requires high precision. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defects of the prior art, which is that the strength of the mounting component is low and the positioning accuracy is high due to the use of an integral mounting component to install all high voltage poles. The present invention provides an electrical connector, an electrical connection assembly, an electric vehicle, and a battery pack.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

[0006] An electrical connector includes a mounting base, a plurality of high-voltage terminals and a plurality of first mounting members, wherein the high-voltage terminals are mounted on the mounting base via the first mounting members, and at least one of the high-voltage terminals is mounted on the first mounting member.

[0007] In this design, the high-voltage terminals are mounted on the mounting base using a first mounting component. This ensures the stability of the high-voltage terminal installation and facilitates a smooth electrical connection between the battery pack and the electric vehicle. Specifically, this embodiment uses multiple first mounting components to install multiple high-voltage terminals on the mounting base. Compared to using a single, integrated mounting component to install all terminals, this approach effectively ensures the strength of the first mounting components and prevents breakage. This further enhances the stability of the high-voltage terminal installation, thereby ensuring a smooth electrical connection between the battery pack and the electric vehicle and improving the stability of the electric vehicle's operation.

[0008] On the other hand, if a single first mounting component is used to install all the poles, the position of each pole needs to be precisely positioned when manufacturing the first mounting component. However, by using multiple separate first mounting components, it is not necessary to position the multiple poles separately during manufacturing, which helps to reduce production difficulty and production costs.

[0009] Preferably, each of the first mounting components is provided with one of the high-voltage terminals.

[0010] In this design, each first mounting component is used to install only one high-voltage terminal, which helps to further improve the installation strength of the terminal, prevent the first mounting component from breaking, and further ensure the smooth and safe electrical connection between the electric vehicle and the battery pack.

[0011] Preferably, the high-voltage poles are symmetrically arranged on both sides of the centerline of the mounting base.

[0012] In this design, the symmetrical arrangement allows the high-voltage terminals to be evenly distributed on the mounting base, avoiding the instability that would occur when the battery pack is connected to the electric vehicle due to the high-voltage terminals being concentrated on one side. On the other hand, it also allows for a more reasonable arrangement of wiring within the electrical connector, preventing interference between leads and ensuring a proper arrangement of the high-voltage terminals and leads within the electrical connector.

[0013] Preferably, the high-voltage terminal includes a positive high-voltage terminal and a negative high-voltage terminal, which are respectively located on both sides of the centerline of the mounting base.

[0014] In this design, the positive high-voltage terminals are uniformly distributed on one side of the center line of the mounting base, and the negative high-voltage terminals are uniformly distributed on the other side of the center line of the mounting base. This will further facilitate the rational arrangement of the positive and negative leads, help ensure the neat and orderly internal structure of the electrical connector, and thus avoid short circuits or poor contact, ensuring the safety and reliability of the electrical connector during use.

[0015] Preferably, the high-voltage poles located on each side of the centerline of the mounting base are arranged in at least one of the following: a linear arrangement, a polygonal arrangement, and a matrix arrangement.

[0016] In this design, different arrangements of high-voltage terminals ensure that they are evenly distributed on the mounting base. This results in a more dispersed and uniform distribution of connection points between the electric vehicle and battery pack connectors, improving the safety and stability of the connection. Conversely, if the high-voltage terminals are concentrated on one side, the connection points at that concentration may bear excessive force, potentially leading to damage or breakage over time and shortening the lifespan of the electrical connectors.

[0017] Preferably, the number of high-voltage terminals is four, with two high-voltage terminals located on each side of the centerline of the mounting base arranged longitudinally, laterally, or diagonally along the mounting base.

[0018] In this scheme, the four high-voltage terminals are arranged in the above manner, which can achieve a uniform arrangement of the four high-voltage terminals on the mounting base.

[0019] Preferably, the number of high-voltage terminals is six, with three high-voltage terminals located on each side of the centerline of the mounting base arranged in a triangular pattern, or arranged longitudinally, laterally, or diagonally along the mounting base.

[0020] In this solution, the three high-voltage terminals located on the same side are arranged in a triangle, which not only enables the six high-voltage terminals to be evenly distributed on the mounting base, but also reduces the length of the electrical connector in the horizontal and vertical directions, thereby reducing the overall size of the electrical connector; of course, the six high-voltage terminals can also be evenly distributed on the mounting base by arranging them along the longitudinal, horizontal or diagonal direction of the mounting base.

[0021] Preferably, the three high-voltage terminals located on each side of the centerline of the mounting base are arranged in a triangular pattern, including two first high-voltage terminals arranged along the longitudinal direction of the mounting base.

[0022] Preferably, the three high-voltage terminals located on each side of the centerline of the mounting base further include a second high-voltage terminal, which does not overlap with the two first high-voltage terminals in the lateral or longitudinal direction of the mounting base.

[0023] In this design, the aforementioned structure allows for a more even distance between the three high-voltage terminals on the same side. This ensures uniformity in the arrangement of the high-voltage terminals while reducing the size of the electrical connector and improving space utilization. If the second high-voltage terminal overlaps with the first high-voltage terminal in both the lateral and longitudinal directions of the mounting base, the distance between them would be too great, hindering the uniform arrangement of the three high-voltage terminals and wasting connector space.

[0024] Preferably, the number of high-voltage terminals is eight, with four high-voltage terminals located on each side of the centerline of the mounting base arranged in a rectangular pattern.

[0025] In this scheme, the eight high-voltage terminals are arranged in the above manner, which can achieve a uniform arrangement of the eight high-voltage terminals on the mounting base.

[0026] Preferably, the electrical connector further includes a low-voltage terminal block disposed on the center line of the mounting base, and the high-voltage terminals are disposed on both sides of the low-voltage terminal block.

[0027] In this design, the low-voltage terminal is positioned in the middle of the mounting base, and is used as the axis of symmetry of the high-voltage terminal. This makes the overall distribution of the high-voltage and low-voltage terminals more compact, which helps to reduce the overall size of the electrical connector. It also facilitates the subsequent reasonable arrangement of the leads and avoids interference between them.

[0028] Preferably, there are multiple low-voltage terminals, and the electrical connector further includes a second mounting member, through which the multiple low-voltage terminals are mounted on the mounting base.

[0029] In this design, a separate second mounting component is used to install the low-voltage terminal, instead of using the same mounting component to install both the low-voltage and high-voltage terminals. This avoids the risk of breakage from the large mounting component, ensuring the stability of the low-voltage and high-voltage terminals. Furthermore, it eliminates the need to separately position the low-voltage and high-voltage terminals during the manufacturing of the mounting component, which helps reduce production difficulty and costs.

[0030] Preferably, the electrical connector further includes a positioning structure, wherein a plurality of the high-voltage terminals are arranged circumferentially around the positioning structure.

[0031] In this design, when the vehicle-side electrical connector and the battery-side electrical connector are connected, the positioning structure aligns the two connectors, thereby aligning their high-voltage and low-voltage terminals, ensuring a smooth and reliable connection. Furthermore, surrounding the high-voltage terminal with the positioning structure further improves the accuracy of the high-voltage terminal alignment.

[0032] Preferably, the electrical connector further includes a grounding terminal, which is disposed on the mounting base.

[0033] The above-mentioned structural form is adopted in this solution to ensure the safety of the electrical connector during use.

[0034] Preferably, the grounding electrode is mounted on the mounting base via the second mounting member, and the grounding electrode is located on one or both sides of the low-voltage electrode.

[0035] In this design, the grounding terminal is mounted on the mounting base via a second mounting component, which improves the stability of the grounding terminal when mounted on the mounting base. The grounding terminal is located on both sides of the low-voltage terminal, making reasonable use of the space on both sides of the low-voltage terminal, which helps to make the internal structure of the electrical connector more compact, thereby reducing the overall size of the electrical connector.

[0036] Preferably, the second mounting component includes a first mounting portion and a second mounting portion, the first mounting portion protruding from the second mounting portion, the low-voltage terminal being disposed in the first mounting portion, and the grounding terminal being disposed in the second mounting portion.

[0037] In this design, since the low-voltage pole is generally small in size, the thickness of the first mounting part used to install the low-voltage pole is greater than the thickness of the second mounting part, thereby improving the structural strength of the first mounting part and ensuring the stability of the connection between the low-voltage pole and the mounting base.

[0038] Preferably, the first mounting component includes a mounting portion and an insulating portion. The insulating portion has a mounting hole adapted to the high-voltage electrode post, and the high-voltage electrode post passes through the mounting hole. The mounting portion extends from the outer wall surface of the insulating portion along the radial direction of the high-voltage electrode post away from the insulating portion, and the mounting portion is fixedly connected to the mounting base.

[0039] In this solution, the insulating part is sleeved on the high-voltage pole to protect it, so as to avoid collision or wear between the high-voltage pole and other components inside the electrical connector. It can also prevent short circuits or poor contact caused by the high-voltage pole coming into contact with other components, thereby ensuring the functional integrity of the high-voltage pole.

[0040] Preferably, the mounting portion has a connection hole for engaging with a fastener, the fastener passing through the mounting portion and the mounting base to securely connect the two.

[0041] Preferably, in the axial direction of the high-voltage pole, the insulating portion protrudes from the surface of the mounting portion.

[0042] In this solution, by adopting the above-mentioned structural form, the insulation part can cover more of the surface of the high-voltage pole, which helps to increase the protection range of the insulation part, thereby further avoiding short circuits or poor contact of the high-voltage pole, and further ensuring the normal use of the high-voltage pole.

[0043] Preferably, the mounting base has a mounting surface for mounting the high-voltage pole and the first mounting member, and the electrical connector further includes a reinforcing member disposed on the mounting surface.

[0044] In this solution, the above-mentioned structural form is adopted, which improves the structural strength of the mounting surface and can prevent the mounting surface from breaking. As a result, the high-voltage pole, low-voltage pole, first mounting component and second mounting component will be more stable when installed on the mounting surface.

[0045] Preferably, the reinforcement is disposed adjacent to at least one of the first mounting members.

[0046] In this solution, since the mounting surface with the first mounting component and the high-voltage pole is more prone to fracture than the mounting surface without the first mounting component, the reinforcement is placed close to the first mounting component to specifically strengthen the mounting surface around the first mounting component.

[0047] Preferably, the reinforcing member includes a first reinforcing member and a second reinforcing member, the first reinforcing member extending laterally along the mounting surface, the second reinforcing member extending longitudinally along the mounting surface, and the first reinforcing member and the second reinforcing member being cross-connected.

[0048] In this solution, the above-mentioned structural form is adopted, which enhances the structural strength and stability of the mounting surface.

[0049] Preferably, the first mounting members of adjacent high-voltage poles are spaced apart, and the first reinforcing member and / or the second reinforcing member surround the outer peripheral surface of at least one of the first mounting members.

[0050] In this solution, the above-mentioned structural form can be used to specifically strengthen the strength of the mounting surface around the first mounting component, further ensuring the connection stability between the first mounting component and the high-voltage terminal, thereby ensuring the stability of the connection between the battery pack and the electric vehicle.

[0051] Preferably, the mounting surface is provided with a plurality of first reinforcing members, which are spaced apart along the longitudinal direction of the mounting surface, and are continuous or discontinuous along the transverse direction of the mounting surface.

[0052] And / or, the mounting surface is provided with a plurality of second reinforcing members, which are spaced apart along the transverse direction of the mounting surface, and are continuous or discontinuous along the longitudinal direction of the mounting surface.

[0053] In this scheme, depending on the different arrangement of the high-voltage poles, there may be interference between the first reinforcing member or the second reinforcing member and the first mounting member. When interference occurs with the first mounting member, the first and second reinforcing members can be discontinuous, i.e., intermittent. When there is no interference with the first mounting member, the first and second reinforcing members can be continuous. In this way, the respective functions of the reinforcing members and the first mounting member can be guaranteed.

[0054] An electrical connection assembly, the electrical connector device comprising two mating electrical connectors, the terminals of the two electrical connectors being connected; wherein at least one of the electrical connectors is an electrical connector as described above.

[0055] In this solution, both the electrical connector installed on the electric vehicle and the electrical connector installed on the battery pack include multiple high-voltage terminals and multiple first mounting components. Each high-voltage terminal of the electrical connector at the vehicle end and the electrical connector at the battery pack end is mounted on a mounting base through a separate first mounting component, thereby ensuring the strength of the first mounting component, avoiding the breakage of the first mounting component, ensuring the installation stability of the high-voltage terminal, and thus ensuring a smooth electrical connection between the electric vehicle and the battery pack, which is beneficial to improving the driving stability of the electric vehicle.

[0056] Preferably, one electrical connector is installed in the electric vehicle and the other electrical connector is installed in the battery pack, the electric vehicle and the battery pack being electrically connected via the electrical connection assembly.

[0057] An electric vehicle, the electric vehicle including the electrical connector as described above.

[0058] In this solution, after the electric vehicle uses the aforementioned electrical connector, when the electric vehicle is connected to the battery pack, it can ensure a smooth electrical connection between the electric vehicle and the battery pack, and at the same time, it is conducive to improving the safety and stability of the electric vehicle during operation.

[0059] A battery pack comprising an electrical connector as described above.

[0060] In this solution, after the battery pack uses the aforementioned electrical connector, when the battery pack is connected to the electric vehicle, it can ensure a smooth electrical connection between the electric vehicle and the battery pack, and at the same time, it is conducive to improving the safety and stability of the electric vehicle.

[0061] The positive and progressive effects of this invention are as follows:

[0062] This invention mounts the high-voltage terminals onto the mounting base using a first mounting member, which helps ensure the stability of the high-voltage terminal installation and thus facilitates a smooth electrical connection between the battery pack and the electric vehicle. Specifically, in this embodiment, multiple high-voltage terminals are mounted onto the mounting base using multiple first mounting members. Compared to using a single, integrated mounting member to mount all terminals, this approach effectively ensures the strength of the first mounting members and prevents breakage. This further enhances the stability of the high-voltage terminal installation, thereby ensuring a smooth electrical connection between the battery pack and the electric vehicle and improving the stability of the electric vehicle's operation.

[0063] On the other hand, if a single first mounting component is used to install all the poles, the position of each pole needs to be precisely positioned when manufacturing the first mounting component. However, by using multiple separate first mounting components, it is not necessary to position the multiple poles separately during manufacturing, which helps to reduce production difficulty and production costs.

[0095] The present invention will be described more clearly and completely below with reference to a preferred embodiment and the accompanying drawings.

[0096] Example 1

[0097] like Figure 1 As shown, this embodiment discloses an electrical connector 100, which includes a mounting base 1, a plurality of high-voltage terminals 2 and a plurality of first mounting members 3. The high-voltage terminals 2 are mounted on the mounting base 1 through the first mounting members 3, and at least one high-voltage terminal 2 is provided on the first mounting member 3.

[0098] Installing the high-voltage terminal 2 onto the mounting base 1 via the first mounting member 3 helps ensure the stability of the high-voltage terminal 2 installation, which in turn helps ensure a smooth electrical connection between the battery pack and the electric vehicle. In particular, in this embodiment, multiple high-voltage terminals 2 are installed on the mounting base 1 separately via multiple first mounting members 3. Compared to using a single integral mounting member to install all terminals, the scheme of installing multiple first mounting members 3 separately can effectively ensure the strength of the first mounting members 3 and avoid the possibility of breakage. This further helps to ensure the installation stability of the high-voltage terminal 2, thereby further ensuring a smooth electrical connection between the battery pack and the electric vehicle and improving the driving stability of the electric vehicle.

[0099] On the other hand, if a single mounting piece is used to install all the poles, the position of each pole needs to be precisely positioned when manufacturing the mounting piece. However, by using multiple separate first mounting pieces 3, it is not necessary to position the multiple poles separately during manufacturing, which helps to reduce production difficulty and production costs.

[0100] like Figures 1-3 As shown, in this embodiment, each first mounting member 3 is provided with a high-voltage terminal 2, meaning each first mounting member 3 is used to install only one high-voltage terminal 2. This helps to further prevent the first mounting member 3 from breaking and further ensures a smooth and safe electrical connection between the electric vehicle and the battery pack. In other embodiments, each first mounting member 3 may be provided with two or more high-voltage terminals 2.

[0101] like Figures 1-3 As shown, the high-voltage terminals 2 are symmetrically arranged on both sides of the center line of the mounting base 1. The symmetrical arrangement allows the high-voltage terminals 2 to be evenly distributed on the mounting base 1, avoiding the situation where the high-voltage terminals 2 are concentrated on one side, which would cause instability when the battery pack is connected to the electric vehicle. On the other hand, it also allows for a more reasonable arrangement of wiring in the electrical connector 100, avoiding interference between the leads and ensuring a reasonable arrangement of the high-voltage terminals 2 and leads in the electrical connector 100.

[0102] The high-voltage terminal 2 includes a positive high-voltage terminal 21 and a negative high-voltage terminal 22. The positive high-voltage terminal 21 and the negative high-voltage terminal 22 are respectively located on both sides of the center line of the mounting base 1. That is to say, the positive high-voltage terminal 21 is uniformly distributed on one side of the center line of the mounting base 1, and the negative high-voltage terminal 22 is uniformly distributed on the other side of the center line of the mounting base 1. In this way, it will further facilitate the reasonable arrangement of the positive and negative leads, help ensure the neat and orderly internal structure of the electrical connector 100, and thus avoid short circuits or poor contact, ensuring the safety and reliability of the electrical connector 100 during use.

[0103] Specifically, the high-voltage terminals 2 located on each side of the centerline of the mounting base 1 are arranged in at least one of the following ways: linear arrangement, polygonal arrangement, and matrix arrangement. The specific arrangement can be selected according to the different numbers of high-voltage terminals 2. When different numbers of high-voltage terminals 2 are arranged in different ways, they can be evenly distributed on the mounting base 1. In this way, when the electrical connector 100 at the electric vehicle end and the electrical connector 100 at the battery pack end are connected, the more dispersed and evenly distributed connection points can improve the safety and stability of the connection between the battery pack and the electric vehicle. If the high-voltage terminals 2 are concentrated on one side, the concentrated connection points may bear more force, which may lead to damage or breakage of the high-voltage terminals 2 after long-term use, which is not conducive to extending the service life of the electrical connector 100.

[0104] When the number of high-voltage terminals 2 is four, in this embodiment, as follows: Figure 2 As shown, the two high-voltage terminals 2 located on each side of the centerline of the mounting base 1 are arranged longitudinally along the mounting base 1. In other embodiments, the two high-voltage terminals 2 located on each side of the centerline of the mounting base 1 can be arranged laterally or diagonally along the mounting base 1. By adopting the aforementioned arrangement, the four high-voltage terminals 2 can be evenly distributed on the mounting base 1.

[0105] When the number of high-voltage terminals 2 is six, in this embodiment, as follows: Figure 1 and Figure 3As shown, the three high-voltage terminals 2 located on each side of the centerline of the mounting base 1 are arranged in a triangular pattern. This not only ensures that the six high-voltage terminals 2 are evenly distributed on the mounting base 1, but also reduces the length of the electrical connector 100 in both the horizontal and vertical directions, thereby reducing the overall size of the electrical connector 100. In other embodiments, the three high-voltage terminals 2 located on each side of the centerline of the mounting base 1 can be arranged along the longitudinal, horizontal, or diagonal direction of the mounting base 1.

[0106] Furthermore, when the number of high-voltage terminals 2 is six, and the three high-voltage terminals 2 located on each side of the centerline of the mounting base 1 are arranged in a triangle, such as... Figure 3 As shown, the three high-voltage terminals 2 located on the same side include two first high-voltage terminals 23, which are arranged longitudinally along the mounting base 1. The three high-voltage terminals 2 located on the same side also include a second high-voltage terminal 24, which does not overlap with the two first high-voltage terminals 23 in the transverse or longitudinal direction of the mounting base 1.

[0107] Specifically, in this embodiment, the second high-voltage terminal 24 and the two first high-voltage terminals 23 do not overlap longitudinally in the mounting base 1, but partially overlap laterally. This ensures a more even distance between the three high-voltage terminals 2 on the same side, reducing the size of the electrical connector 100 and improving space utilization while maintaining the uniformity of the high-voltage terminal arrangement. In other optional embodiments, the second high-voltage terminal 24 and the two first high-voltage terminals 23 may also not overlap laterally in the mounting base 1, but partially overlap longitudinally. However, if the second high-voltage terminal 24 and the first high-voltage terminals 23 do not overlap laterally or longitudinally in the mounting base 1, the distance between them will be too large, which is not conducive to ensuring the uniform arrangement of the three high-voltage terminals 2 and wastes space in the electrical connector 100.

[0108] When there are eight high-voltage terminals 2, the four high-voltage terminals 2 located on each side of the centerline of the mounting base 1 are arranged in a rectangular pattern. By adopting the aforementioned arrangement, the eight high-voltage terminals 2 can be evenly distributed on the mounting base 1.

[0109] Of course, in other embodiments, the number of high-voltage terminals 2 can be arbitrary. The selection of the number of high-voltage terminals 2 can be based on the power output required by the electric vehicle. For example, when the electric vehicle requires a large power output, more high-voltage terminals 2 can be set. The four, six, and eight high-voltage terminals 2 schemes disclosed in this embodiment are all applicable to heavy-duty electric trucks.

[0110] like Figures 1-3As shown, the electrical connector 100 also includes a low-voltage terminal 4, which is located on the center line of the mounting base 1, and high-voltage terminals 2 are located on both sides of the low-voltage terminal 4. Positioning the low-voltage terminal 4 in the middle of the mounting base 1 and using it as the axis of symmetry for the high-voltage terminal 2 makes the overall distribution of the high-voltage terminal 2 and low-voltage terminal 4 more compact, which helps reduce the overall size of the electrical connector 100. Furthermore, it facilitates the subsequent rational arrangement of the leads and avoids interference between them.

[0111] Furthermore, there are multiple low-voltage terminals 4, and the electrical connector 100 also includes a second mounting component 5. Multiple low-voltage terminals 4 are mounted on the mounting base 1 through the second mounting component 5. The low-voltage terminals 4 are mounted separately using the second mounting component 5, instead of mounting the low-voltage terminals 4 and the high-voltage terminals 2 through the same mounting component. On the one hand, this avoids the situation where large-sized mounting components are prone to breakage, ensuring the installation stability of the low-voltage terminals 4 and the high-voltage terminals 2. On the other hand, it eliminates the need to separately position the low-voltage terminals 4 and the high-voltage terminals 2 when manufacturing the mounting component, which helps to reduce production difficulty and production costs.

[0112] The electrical connector 100 also includes a positioning structure 6. Multiple high-voltage terminals 2 are arranged circumferentially around the positioning structure 6. When the vehicle-side electrical connector 100 and the battery-side electrical connector 100 are connected, the positioning structure 6 aligns the positions of the two electrical connectors 100, thereby aligning the high-voltage terminals 2 and low-voltage terminals 4 of the two electrical connectors 100, ensuring a smooth and reliable connection. Furthermore, surrounding the high-voltage terminals 2 around the positioning structure 6 further improves the accuracy of the alignment of the high-voltage terminals 2 of the two electrical connectors 100.

[0113] To ensure the safety of the electrical connector 100 during use, the electrical connector 100 also includes a grounding terminal 7, which is disposed on the mounting base 1.

[0114] The grounding terminal 7 is mounted on the mounting base 1 via the second mounting member 5, thereby improving the stability of the grounding terminal 7 when mounted on the mounting base 1. In this embodiment, the grounding terminal 7 is located on both sides of the low-voltage terminal 4, making reasonable use of the space on both sides of the low-voltage terminal 4, which helps to make the internal structure of the electrical connector 100 more compact, thereby reducing the overall size of the electrical connector 100. In other embodiments, the grounding terminal 7 may be located on one side of the low-voltage terminal 4.

[0115] like Figure 5As shown, the second mounting component 5 includes a first mounting portion 51 and a second mounting portion 52. The first mounting portion 51 protrudes from the second mounting portion 52. The low-voltage terminal 4 is disposed in the first mounting portion 51, and the grounding terminal 7 is disposed in the second mounting portion 52. Since the low-voltage terminal is generally small in size, the thickness of the first mounting portion 51 used to mount the low-voltage terminal 4 is greater than the thickness of the second mounting portion 52, thereby improving the structural strength of the first mounting portion 51 and ensuring the stability of the connection between the low-voltage terminal 4 and the mounting base 1.

[0116] like Figure 4 As shown, the first mounting component 3 includes a mounting portion 31 and an insulating portion 32. The insulating portion 32 has a mounting hole 321 adapted to the high-voltage electrode 2, through which the high-voltage electrode 2 passes. The mounting portion 31 extends from the outer wall surface of the insulating portion 32 along the radial direction of the high-voltage electrode 2 away from the insulating portion 32, and is fixedly connected to the mounting base 1. Both the high-voltage electrode 2 and the insulating portion 32 are fixedly connected to the mounting base 1 through the mounting portion 31. The insulating portion 32, sleeved on the high-voltage electrode 2, protects the high-voltage electrode 2 to prevent it from colliding or abrading with other components inside the electrical connector 100, and also prevents short circuits or poor contact caused by contact between the high-voltage electrode 2 and other components, thereby ensuring the functional integrity of the high-voltage electrode 2.

[0117] In the axial direction of the high-voltage pole 2, the insulating part 32 protrudes from the surface of the mounting part 31, so that the insulating part 32 can cover more of the surface of the high-voltage pole 2, which helps to increase the protection range of the insulating part 32, thereby further avoiding short circuits or poor contact of the high-voltage pole 2, and further ensuring the normal use of the high-voltage pole 2.

[0118] Specifically, the mounting part 31 has a connection hole for engaging with the fastener 8. The fastener 8 passes through the mounting part 31 and the mounting base 1 to securely connect the two. The fastener 8 can be a bolt, stud, screw, etc.

[0119] like Figure 6 As shown, the mounting base 1 has a mounting surface 11 for mounting the pole and the first mounting member 3. In order to improve the structural strength of the mounting surface 11, the electrical connector 100 also includes a reinforcing member 9. The reinforcing member 9 is provided on the mounting surface 11, thereby preventing the mounting surface 11 from breaking. As a result, the high voltage pole 2, low voltage pole 4, first mounting member 3 and second mounting member 5 will be more stable when mounted on the mounting surface 11.

[0120] The reinforcing member 9 is positioned close to the first mounting member 3. Since the mounting surface 11 with the first mounting member 3 and the high-voltage pole 2 is more prone to breakage than the mounting surface 11 without the first mounting member 3, this embodiment positions the reinforcing member 9 close to the first mounting member 3 to specifically strengthen the strength of the mounting surface 11 around the first mounting member 3, while the rest of the mounting surface 11 does not need to be reinforced, thus saving processing steps and materials.

[0121] Specifically, the reinforcing member 9 includes a first reinforcing member 91 and a second reinforcing member 92. The first reinforcing member 91 extends laterally along the mounting surface 11, and the second reinforcing member 92 extends longitudinally along the mounting surface 11. The first reinforcing member 91 and the second reinforcing member 92 are cross-connected, thereby strengthening the structural strength and structural stability of the mounting surface 11.

[0122] In this embodiment, the first mounting members 3 of adjacent high-voltage terminals 2 are spaced apart, and the first reinforcing member 91 and the second reinforcing member 92 surround the outer peripheral surface of the first mounting member 3. The first reinforcing member 91 and the second reinforcing member 92 may surround only a portion of the outer peripheral surface of the first mounting member 3, or they may surround all of the outer peripheral surface of the first mounting member 3. This allows for targeted reinforcement of the mounting surface 11 around the first mounting member 3, further ensuring the connection stability between the first mounting member 3 and the high-voltage terminal 2, and thus ensuring the stability of the connection between the battery pack and the electric vehicle. Alternatively, only the first reinforcing member 91 or only the second reinforcing member 92 may surround the outer peripheral surface of the first mounting member 3.

[0123] Furthermore, the mounting surface 11 is provided with a plurality of first reinforcing members 91, which are spaced apart along the longitudinal direction of the mounting surface 11, and are continuous or discontinuous along the transverse direction of the mounting surface 11. The mounting surface 11 is also provided with a plurality of second reinforcing members 92, which are spaced apart along the transverse direction of the mounting surface 11, and are continuous or discontinuous along the longitudinal direction of the mounting surface 11. Depending on the different arrangements of the high-voltage poles 2 described above, interference may occur between the first reinforcing member 91 or the second reinforcing member 92 and the first mounting member 3. When interference occurs, the first reinforcing member 91 and the second reinforcing member 92 can be discontinuous, i.e., discontinuous. When no interference occurs, the first reinforcing member 91 and the second reinforcing member 92 can be continuous. This ensures the realization of the respective functions of the reinforcing member 9 and the first mounting member 3.

One electrical connector 100 is installed in an electric vehicle, and the other electrical connector 100 is installed in a battery pack, and the electric vehicle and the battery pack are electrically connected through the electrical connection assembly 200.

[0126] Both the electrical connector 100 installed in the electric vehicle and the electrical connector 100 installed in the battery pack include multiple high-voltage terminals 2 and multiple first mounting members 3. Each high-voltage terminal 2 of the electrical connector 100 at the vehicle end and the electrical connector 100 at the battery pack end is mounted on the mounting base 1 through a separate first mounting member 3. This ensures the strength of the first mounting member 3, avoids the breakage of the first mounting member 3, and ensures the installation stability of the high-voltage terminal 2. This also ensures a smooth electrical connection between the electric vehicle and the battery pack, which helps to improve the driving stability of the electric vehicle.
