[0034] To enable those skilled in the art to better understand the technical solutions of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] In the description of the embodiments of this application, it should be noted that the orientation or positional relationship indicated by "up", "down", "left", "right", "front", "back", etc. is based on the accompanying drawings and is only for the convenience of description, and is not intended to indicate or imply that the device 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.

[0036] like Figure 1 , Figure 2 As shown, Figure 1 This is a schematic diagram of the structure of a high-voltage connector 1 in an embodiment of this application; Figure 2 for Figure 1 Exploded view of medium- and high-voltage connector 1.

[0037] This application provides a high-voltage connector 1, including a socket body 11, terminals 12, and a sealing assembly 13. The socket body 11 has a receiving portion, and the terminals 12 are mounted in the receiving portion. The sealing assembly 13 includes a first sealing member 131, which is mounted between the terminals 12 and the inner wall surface of the receiving portion. A first direction and a second direction are defined. The first direction is parallel to the insertion direction of the terminals 12 and the socket body 11, and the second direction is also parallel to the socket direction of the terminals 12 and the socket body 11. The first direction and the second direction are opposite to each other.

[0038] Terminal 12 has a protrusion 122, and the protrusion 122 has a first limiting wall 122a along a first direction. One side of the first sealing member 131 abuts against the first limiting wall 122a. The receiving portion has a second limiting wall 1121a along a second direction, and the other side of the first sealing member 131 abuts against the second limiting wall 1121a. The receiving portion has a first recess 1121, and the first sealing member 131 is located in the first recess 1121, such as... Figure 6 As shown, Figure 6 for Figure 5 A cross-sectional view along the AA direction is shown. A first limiting wall 122a is provided on the side of the protrusion 122 near the receiving portion along the first direction, and a second limiting wall 1121a is provided on the side of the first recess 1121 near the protrusion 122 along the second direction. The first sealing member 131 abuts against the first limiting wall 122a and the second limiting wall 1121a on both sides along the first direction, respectively, restricting the displacement of the first sealing member 131 along the first and second directions. By using the first sealing member to seal the terminal individually, the sealing performance of the high-voltage connector can be improved, ensuring the safety of the terminal. In this embodiment, the shape of the first sealing member 131 is not limited. For example, the first sealing member 131 is a sealing gasket, which is directly fitted onto the terminal 12. Furthermore, the first sealing member 131 is provided with multiple ribs, which extend in a direction perpendicular to the first direction to prevent water and contaminants from entering between the terminal 12 and the receiving portion, ensuring the long-term sealing effect of the first sealing member 131.

[0039] The receiving portion is further provided with a second recess 1122. The first recess 1121 and the second recess 1122 are distributed along the second direction, and the recess width of the second recess 1122 is greater than the recess width of the first recess 1121. The protrusion 122 is located in the second recess 1122. The first limiting wall 122a of the protrusion 122 and the side of the second recess 1122 near the first recess 1121 abut against each other.

[0040] In some embodiments, one of the terminal 12 and the receiving portion is provided with a snap-fit ​​portion 121a, and the other is provided with a snap-fit ​​mating portion 11a, which snaps together. The snap-fit ​​portion 121a is provided on both sides of the terminal 12 symmetrical about the insertion direction, and the snap-fit ​​mating portion 11a is correspondingly provided in the receiving portion; or, the snap-fit ​​portion 121a is provided on both sides of the inner wall surface of the receiving portion symmetrical about the insertion direction, and the snap-fit ​​mating portion 11a is correspondingly provided in the terminal 12, which snaps together with the snap-fit ​​mating portion 11a, fixing the terminal 12 to the receiving portion and restricting the displacement of the terminal 12.

[0041] like Figure 3 As shown, Figure 3 for Figure 2 A magnified view of a section at point B in the middle.

[0042] In some embodiments, the snap-fit ​​portion 121a is a barb, with multiple barbs distributed along the insertion direction between the terminal 12 and the socket body 11. The barb has an inclined surface and a reverse hook; the inclined surface can smoothly slide into the snap-fit ​​portion 11a, and the hook can engage with the snap-fit ​​portion 11a to form an interlock and prevent retraction. In this embodiment, multiple barbs are provided symmetrically on both sides of the terminal 12 along the insertion direction, and the multiple barbs are distributed along the insertion direction. When the terminal 12 is inserted into the socket body 11, the barbs enter the corresponding snap-fit ​​portion 11a of the receiving portion along the first direction, allowing the terminal 12 to engage with the receiving portion, preventing the terminal 12 from retracting in the receiving portion and ensuring the reliability of the connection.

[0043] In some embodiments, a first slot 1111 is provided at one end of the receiving portion near the terminal 12, and at least a portion of the terminal 12 is exposed in the first slot 1111. This can be understood as follows: after the plug is connected to the socket body 11, it needs to contact the terminal 12. Providing the first slot 1111 at one end of the receiving portion near the terminal 12 exposes at least a portion of the terminal 12 in the first slot 1111, facilitating contact between the plug and the terminal 12, and enabling the socket body 11 to establish a reliable electrical connection path between the power supply and the load.

[0044] In some embodiments, terminal 12 includes a contact end 121 and a connecting end 123 disposed along a second direction, with a protrusion 122 located between the contact end 121 and the connecting end 123. The contact end 121 is inserted into the receiving portion. The connecting end 123 includes a bent section 1231 and a mounting section 1232. The bent section 1231 is angled relative to the contact end 121, and the mounting section 1232 is located at one end of the bent section 1231 and extends along the second direction. It can be understood that terminal 12 includes a contact end 121, a protrusion 122, and a connecting end 123 distributed along two directions. The contact end 121 is inserted into the receiving portion and engages with it. The protrusion 122 abuts against the second recess 1122 of the receiving portion. The connecting end 123 includes a bent section 1231 and a mounting section 1232 distributed along the second direction. The bent section 1231 is angled relative to the contact end 121, and the mounting section 1232 extends along the second direction. Mounting section 1232 is used to place and install copper busbars. Bending section 1231 ensures that the center of the copper busbar and the socket body 11 are on the same horizontal plane. In this embodiment, the angle between bending section 1231 and contact end 121 is not limited; it can be set according to actual usage requirements. To facilitate the connection between mounting section 1232 and copper busbar, a riveted nut is also provided on mounting section 1232. Fasteners are used to connect the copper busbar and the nut to fix the copper busbar and terminal 12.

[0045] like Figure 4 , Figure 5 As shown, Figure 4 for Figure 1 The main view; Figure 5 for Figure 4 Side view.

[0046] In some embodiments, the socket body 11 includes a body portion 111, with a receiving portion disposed within the body portion 111. The body portion 111 is provided with a plurality of guide strips 1112, which extend along the insertion direction between the terminal 12 and the socket body 11. This embodiment does not limit the number of guide strips 1112; it can be set according to actual installation requirements. A plurality of guide strips 1112 are provided above the outer wall surface of the body portion 111 to guide the plug and socket body 11 to insert along a second direction, ensuring the plug can be installed correctly and guaranteeing proper connection between the plug and the socket body 11. (See also...) Figure 1 As shown, two guide strips 1112 are provided below the outer wall of the main body 111, and corresponding guide parts are also provided on the plug to facilitate the connection between the plug and the main body 111. The distance between the two guide strips 1112 located below is not limited, and the distance can be adjusted according to the actual connection requirements to accommodate plugs with different guide parts.

[0047] In some embodiments, the body portion 111 further includes a connector 1113 extending in a direction away from the body portion 111, and the connector 1113 is used to lock the plug. This embodiment does not limit the connector 1113; exemplarily, in this embodiment, the connector 1113 is a boss, and the boss protrudes in a direction away from the body portion 111. The plug has a corresponding locking portion; after the plug is inserted into the socket body 11, the connector 1113 lifts the locking portion, locking the plug and plug body.

[0048] In some embodiments, the body portion 111 is further provided with a through hole 1114, and the socket body 11 also includes an inner cavity, with the through hole 1114 communicating with the inner cavity. This embodiment does not limit the number or position of the through holes 1114. For example, this embodiment provides two through holes 1114, and the two through holes 1114 are respectively located on both sides of the connector 1113 along the first direction. The through holes 1114 ensure that when the plug is inserted into the socket body 11, the gas inside the socket body 11 can be discharged, making the installation of the plug and socket body 11 easier.

[0049] In some embodiments, the socket body 11 further includes a mounting portion 112 disposed on the outer wall surface of the body portion 111; the sealing assembly 13 further includes a second sealing member 132, which is mounted on the side of the mounting portion 112 away from the guide strip 112. A second slot 1123 is provided on the side of the mounting portion 112 away from the guide strip 112, with the opening of the second slot 1123 facing away from the plug, and the second sealing member 132 is fixed to the second slot 1123. After the socket body 11 is connected to the socket hole wall, a portion of the second sealing member 132 is located in the second slot 1123, and another portion is located in the gap between the socket body 11 and the socket hole wall, which is used to prevent water and contaminants from entering the socket body 11 and ensure the long-term sealing effect of the second sealing member 132. This embodiment does not limit the shape of the second seal 132. For example, the second seal 132 is a sealing gasket with multiple protrusions, which can increase the friction between the second slot 1123 and the wall of the socket hole, preventing it from slipping out of the second slot 1123 while ensuring a seal.

[0050] In some embodiments, the mounting portion 112 is provided with a protective strip 1126, which is located on the side of the mounting portion 112 near the guide strip 1112. The protective strip 1126 surrounds the body portion 111 and has a gap with the outer wall surface of the body portion 111. In connection with the plug and socket body 11, it can be understood that after the plug and socket body 11 are inserted, the end of the plug contacts the side of the mounting portion 112 near the guide strip 1112. At this contact surface, a protective strip 1126 surrounds the body portion 111. The end of the plug is inserted into the gap between the protective strip 1126 and the body portion 111. The protective strip 1126 covers the end of the plug to increase its vibration resistance after connection and reduce plug misalignment.

[0051] A positioning part 1125 is also provided on the side of the mounting part 112 away from the second direction. The positioning part 1125 can be a column or an irregular shape; this embodiment is not limited as long as it can provide a positioning effect. A corresponding positioning mating part is provided on the wall of the socket hole to align and insert the socket body 11 with the wall of the socket hole, facilitating the installation of the socket body 11. To facilitate the installation between the socket body 11 and the wall of the socket hole, the mounting part 112 is also provided with a plurality of through holes 1124. The through holes 1124 penetrate the mounting part 112 along the first direction, and fasteners can be inserted into the through holes 1124 to fix the socket body 11 and the wall of the socket hole. Furthermore, a bushing 14 is provided inside the through hole 1124. Pressing the bushing 14 into the through hole 1124 can increase the installation strength of the fastener, making the connection between the socket body 11 and the wall of the socket hole tighter.

[0052] This embodiment also provides a high-voltage connector device, including a plug and a high-voltage connector. The high-voltage connector is the high-voltage connector 1 of any of the above embodiments, and has the same technical effect as the high-voltage connector 1 in the above embodiments, so it will not be described again. The plug is inserted into the high-voltage connector 1 along the second direction. This can be understood as follows: after the plug is inserted along the guide strip 1112 of the socket body 11, it is locked with the connector 1113, and then the plug contacts the terminal 12 to establish an electrical connection path.

[0053] This document uses specific examples to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make several improvements and modifications to this application without departing from the principles of this application, and these improvements and modifications also fall within the protection scope of the claims of this application.
