[0033] To make the objectives, technical solutions, and beneficial effects of this application clearer, the following detailed description, in conjunction with the accompanying drawings and specific embodiments, further illustrates this application. It should be understood that the specific embodiments described in this specification are merely for explaining this application and are not intended to limit it.

[0034] In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0035] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0036] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0037] In the embodiments of this application, reference is made to Figures 1 to 7 This application provides a high-voltage connector 100, which has a first direction X, a second direction Z, and a third direction Y that intersect each other. Exemplarily, the high-voltage connector 100 also has a first direction X, a second direction Z, and a third direction Y that are perpendicular to each other. Here, "perpendicular" refers to a state where the angle formed by two lines, a line and a surface, or a surface is 89° to 91°.

[0038] Specifically, refer to Figures 1 to 2 The high-voltage connector 100 includes: a housing 110, a connection terminal 120, an electrical connector 130, and a flexible adapter 140.

[0039] Specifically, the connecting terminal 120 is installed within the housing 110 and is used for electrical connection with the terminals of other connectors; at least a portion of the electrical connector 130 is installed within the housing 110 and is electrically connected to the connecting terminal 120, and is used for electrical connection with external electrical components; the flexible adapter 140 is installed within the housing 110 and is disposed between the connecting terminal 120 and the electrical connector 130, and the connecting terminal 120 is electrically connected to the electrical connector 130 through the flexible adapter 140, thereby forming a direct electrical connection circuit of connecting terminal 120-flexible adapter 140-electrical connector 130. The flexible adapter 140 is configured to bear the stress generated by the displacement of the electrical connector 130, that is, the flexible adapter 140 can undergo corresponding deformation due to the stress generated by the displacement of the electrical connector 130.

[0040] The housing 110 is made of an insulating material. For example, in this application, the housing 110 is made of plastic, but it is not limited thereto.

[0041] The connecting terminal 120 is made of conductive metal. For example, in this application, the connecting terminal 120 is made of high-strength copper alloy such as copper-zinc alloy or copper-tin alloy, but it is not limited to this.

[0042] The electrical connector 130 is made of a conductive metal. For example, in this application, the electrical connector 130 is made of aluminum, but it is not limited thereto.

[0043] The flexible adapter 140 is made of a flexible conductive material. For example, in this application, the flexible adapter 140 is made of high-purity copper, but it is not limited thereto.

[0044] Understandably, to accommodate high-power fast charging conditions, existing connectors use aluminum busbars to electrically connect to the terminals. However, during connector assembly and subsequent use, the aluminum busbars may shift, applying stress to the terminals and causing damage, thus affecting the normal operation of the connector.

[0045] This application provides a flexible adapter 140 between the electrical connector 130 and the connecting terminal 120. The flexible adapter 140 enables an electrical connection between the electrical connector 130 and the connecting terminal 120, achieving a flexible connection between them. When the electrical connector 130 is displaced, stress is applied to the flexible adapter 140, causing it to deform. The connecting terminal 120 remains unaffected. This allows the flexible adapter 140 to absorb the stress generated by the displacement of the electrical connector 130, eliminating the impact of the electrical connector 130 on the contact performance of the connecting terminal 120. This improves the reliability and safety performance of the high-voltage connector 100, ensuring its normal operation.

[0046] In some embodiments, refer to Figures 1 to 2 Multiple connection terminals 120, electrical connectors 130, and flexible adapters 140 are provided. Multiple electrical connectors 130 and multiple flexible adapters 140 extend along the first direction X, and multiple connection terminals 120, multiple electrical connectors 130, and multiple flexible adapters 140 are arranged at intervals in the second direction Y. Each connection terminal 120 is electrically connected to a corresponding electrical connector 130 through a corresponding flexible adapter 140 to ensure that the high-voltage connection can use a large charging current and can be applied to different application scenarios, so that the high-voltage connector 100 has good compatibility and flexibility.

[0047] In some embodiments, refer to Figures 8 to 10 The flexible adapter 140 includes a first connecting part 141, a deformable part 142, and a second connecting part 143.

[0048] Specifically, the deformable portion 142 is disposed between the first connecting portion 141 and the second connecting portion 143, and the first connecting portion 141 is connected to the second connecting portion 143 through the deformable portion 142. The first connecting portion 141 is disposed closer to the connecting terminal 120 than the second connecting portion 143, and the first connecting portion 141 is fixedly connected to the connecting terminal 120, that is, the flexible adapter 140 is electrically connected to the connecting terminal 120 via the first connecting portion 141; the second connecting portion 143 is fixedly connected to the electrical connector 130, that is, the flexible adapter 140 is electrically connected to the electrical connector 130 via the second connecting portion 143, to form a direct electrical connection circuit of connecting terminal 120-first connecting portion 141-deformable portion 142-second connecting portion 142-electrical connector 130. The deformable portion 142 is configured to bear the stress generated by the displacement of the electrical connector 130, so as to produce corresponding deformation.

[0049] The first connecting portion 141, the deformable portion 142, and the second connecting portion 143 can be integrally formed, meaning they form a single, integrated structure. Alternatively, they can be separately configured and fixedly connected in pairs. For example, the deformable portion 142 can be fixedly connected to the first connecting portion 141 and the second connecting portion 143 via welding or other processes. No specific limitations are imposed in this application; the configuration can be tailored to the specific circumstances. For example, in this application, the first connecting portion 141, the deformable portion 142, and the second connecting portion 143 are integrally cast.

[0050] Understandably, this application provides a deformable part 142 to absorb the stress and deformation caused by the displacement of the electrical connector 130, thereby eliminating the influence of the electrical connector 130 on the contact performance of the connection terminal 120, improving the reliability and safety performance of the high-voltage connector 100, and ensuring the normal use of the high-voltage connector 100.

[0051] In some embodiments, the second connecting part 143 is welded and fixed to the electrical connector 130 to realize the connection and electrical connection between the flexible adapter 140 and the electrical connector 130, and facilitate the assembly connection between the flexible adapter 140 and the electrical connector 130, thereby improving the overall assembly efficiency of the high-voltage connector 100.

[0052] For example, the electrical connector 130 may be welded to the second connection portion 143 using ultrasonic welding or resistance welding, but is not limited thereto.

[0053] In some embodiments, refer to Figures 3 to 5 and Figures 8 to 10 A first through hole 121 is provided on the side of the connecting terminal 120 near the first connecting part 141, and a second through hole 1411 is provided on the first connecting part 141, and the second through hole 1411 communicates with the first through hole 121.

[0054] The first through hole 121 and the second through hole 1411 can be of any shape. For example, in this application, both the first through hole 121 and the second through hole 1411 are circular, but are not limited thereto.

[0055] Specifically, the high-voltage connector 100 further includes a first locking member 161 and a second locking member 162. The second locking member 162 is fixedly installed inside the housing 110, and the first locking member 161 passes through the first through hole 121 and the second through hole 1411 and is fixedly connected to the second locking member 162, thereby connecting the connecting terminal 120 to the first connecting part 141 and realizing the electrical connection between the connecting terminal 120 and the first connecting part 141. This ensures the normal electrical connection of the high-voltage connector 100 while ensuring the overall structural stability of the high-voltage connector 100, improving the reliability and safety performance of the high-voltage connector 100. At the same time, it facilitates the assembly connection between the connecting terminal 120 and the flexible adapter 140, improving the overall assembly efficiency of the high-voltage connector 100.

[0056] The connection between the first locking member 161 and the second locking member 162 can be by screwing, riveting or snap-fit, but is not limited to these methods.

[0057] For example, in this application, the first locking member 161 is a bolt and the second locking member 162 is a nut. The first locking member 161 passes through the first through hole 121 and the second through hole 1411 and is screwed to the second locking member 162 to realize the locking and fixing between the connecting terminal 120 and the first connecting part 141, and to realize the electrical connection between the connecting terminal 120 and the first connecting part 141.

[0058] In some embodiments, refer to Figures 2 to 5 The high-voltage connector 100 also includes a first fixing member 150, which is disposed inside the housing 110 and is used to limit and fix the connecting terminal 120 and the flexible adapter 140.

[0059] Specifically, the first fixing member 150 includes: a first fixing part 151 and a second fixing part 152 connected to each other. The first fixing part 151 and the second fixing part 152 cooperate to form a fixing cavity 153. The connecting terminal 120 and the flexible adapter 140 are fixedly installed in the fixing cavity 153 to realize the limiting and fixing of the connecting terminal 120 and the flexible adapter 140, so as to prevent the connecting terminal 120 and the flexible adapter 140 from moving freely, ensuring the overall structural stability of the high-voltage connector 100 and improving the reliability of the high-voltage connector 100.

[0060] Both the first fixing part 151 and the second fixing part 152 are made of insulating material. For example, in this application, both the first fixing part 151 and the second fixing part 152 are made of plastic, but are not limited thereto.

[0061] In some embodiments, refer to Figures 2 to 7The first fixing part 151 has a receiving groove 1511, and the second locking member 162 is embedded in the receiving groove 1511. Specifically, the second locking member 162 and the groove wall of the receiving groove 1511 adopt an interference fit to ensure the firmness of the second locking member 162, further ensuring the overall structural stability of the high-voltage connector 100 and improving the reliability of the high-voltage connector 100.

[0062] Specifically, the housing 110 has a first clearance hole 111, and the second fixing part 152 has a second clearance hole 1521. The first clearance hole 111, the second clearance hole 1521, the first through hole 121 and the second through hole 1411 are connected in sequence. The first locking member 161 is installed on the first fixing member 150 from the first clearance hole 111 and the second clearance hole 1521.

[0063] Understandably, when assembling the high-voltage connector 100, after the initial assembly of the connecting terminal 120 and the flexible adapter 140, the connecting terminal 120 and the flexible adapter 140 are initially fixed using the first fixing part 151 and the second fixing part 152. Then, the assembly unit of the connecting terminal 120, the flexible adapter 140, and the first fixing part 150 is assembled into the housing 110, ensuring that the first clearance hole 111, the second clearance hole 1521, the first through hole 121, and the second through hole 1411 are sequentially connected. The first locking member 161 passes through the second clearance hole 1521 from the first clearance hole 111, and simultaneously passes through the first through hole 121 and the second through hole 1411 and is screwed to the second locking member 162 to realize the locking and fixing between the connecting terminal 120 and the first connecting part 141. This facilitates the overall assembly of the components in the high voltage connector 100, prevents mutual interference during the assembly of the components, improves the assembly efficiency of the high voltage connector 100, and thus improves the production efficiency of the high voltage connector 100.

[0064] In some embodiments, refer to Figures 3 to 5 The housing 110 is provided with a first limiting part 112, and the second fixing part 152 is provided with a second limiting part 154. The second limiting part 154 abuts against the first limiting part 112 to limit the first fixing part 150, prevent the first fixing part 150 from being over-assembled, ensure the assembly position of the first fixing part 150 during assembly, and improve the assembly efficiency of the high voltage connector 100.

[0065] A limiting groove 113 is provided on the inner wall of the housing 110, and an elastic limiting part 155 is provided on the first fixing part 151. The elastic limiting part 155 is embedded in the limiting groove 113 to further realize the limiting and fixing between the housing 110 and the first fixing member 150, ensure the structural stability of the first fixing member 150, and thus ensure the overall structural stability of the high voltage connector 100 and improve the reliability of the high voltage connector 100.

[0066] In some embodiments, refer to Figures 3 to 7 The high-voltage connector 100 also includes a cover 114, which is fixedly connected to the housing 110 and blocks the first clearance hole 111 to ensure the overall airtightness of the high-voltage connector 100, improve the sealing performance of the high-voltage connector 100, thereby improving the waterproof performance and safety performance of the high-voltage connector 100, and ensuring the safety of signal transmission in the path of the high-voltage connector 100.

[0067] The cover 114 is made of an insulating material. For example, in this application, the cover 114 is made of plastic, but it is not limited thereto.

[0068] Specifically, the cover 114 and the housing 110 can be connected and fixed by any mechanical fixing method. For example, the cover 114 and the housing 110 can be fixed by snap-fit ​​or by screw, but are not limited to these methods.

[0069] A sealing element is also provided between the cover 114 and the housing 110 to ensure the airtightness of the connection between the cover 114 and the housing 110, improve the waterproof performance of the high voltage connector 100, and ensure the safety of signal transmission in the path of the high voltage connector 100.

The protective member 180 is installed on the side of the housing 110 near the electrical connector 130, and the electrical connector 130 passes through the protective member 180 to isolate the internal space of the housing 110 from the external space, achieving preliminary protection for the high-voltage connector 100, ensuring the overall airtightness of the high-voltage connector 100, improving the sealing performance of the high-voltage connector 100, and further improving the waterproof performance and safety performance of the high-voltage connector 100, ensuring the security of signal transmission in the path of the high-voltage connector 100.

[0071] The second fastener 170 is made of an insulating material. For example, in this application, the second fastener 170 is made of plastic, but it is not limited thereto.

[0072] The protective member 180 is made of an insulating material. For example, in this application, the second fastener 170 is made of plastic, but is not limited thereto.

[0073] In some embodiments, refer to Figure 2 The protective component 180 includes a first protective part 181 and a second protective part 182 that are separately provided, and the first protective part 181 and the second protective part 182 are fixedly connected to form the protective component 180.

[0074] Specifically, the first protective part 181 is provided with a snap-fit ​​part 183, and the second protective part 182 is provided with a slot 184. When the high-voltage connector 100 is assembled, the first protective part 181 and the second protective part 182 are assembled on the side of the housing 110 near the electrical connector 130, and the snap-fit ​​part 183 is snapped into the slot 184. The cooperation between the snap-fit ​​part 183 and the slot 184 realizes the fixed connection between the first protective part 181 and the second protective part 182, thereby realizing the assembly and fixation between the protective part 180 and the housing 110, which facilitates the overall assembly of the high-voltage connector 100 and improves the assembly efficiency of the high-voltage connector 100.

[0075] In some embodiments, refer to Figures 2 to 5 The high-voltage connector 100 further includes a first sealing element 191 and a second sealing element 192. A portion of the first sealing element 191 is disposed between the housing 110 and the protective element 180, and another portion is disposed between the housing 110 and the second fixing element 170. This ensures the sealing performance between the housing 110 and the protective element 180, and between the housing 110 and the second fixing element 170, improving the overall airtightness and sealing performance of the high-voltage connector 100, thereby enhancing its waterproof and safety performance and ensuring the security of signal transmission within the high-voltage connector 100's path.

[0076] The first seal 191 and the second seal 192 are both made of rubber, but are not limited to this.

[0077] Specifically, during assembly, the second seal 192 can be pre-assembled on the outer surface of the electrical connector 130 before the flexible adapter 140 and the electrical connector 130 are welded, so as to avoid the second seal 192 being damaged when the flexible adapter 140 and the electrical connector 130 are welded and then assembled, thus ensuring the sealing effect of the second seal 192.
