[0038] In the connector 100 of the embodiment of the present application, the first housing 10 is provided with a first accommodating space 101, the second housing 20 is provided with a second accommodating space 202, and the second housing 20 is detachable and sealedly connected to the first housing 10. The first terminal 110 is at least partially disposed in the first accommodating space 101, and the second terminal 210 is accommodated in the second accommodating space 202 and electrically connected to the first terminal 110. The first sealing member 31 is connected to the inner wall of the second accommodating space 202, and is used for sealingly connecting with the wire inserted into the second accommodating space 202 and connected to the second terminal 210.

[0039] The connector 100 of the embodiment of the present application can be used for connecting and charging low-voltage electrical equipment of a vehicle 1000. The first housing 10 and the second housing 20 are sealed and connected to protect the first terminal 110 and the second terminal 210 from being exposed during charging. The first sealing member 31 is sealed and connected to the wire connected to the second terminal 210, which enhances the sealing and waterproof performance of the connector 100, thereby making the first terminal 110 and the second terminal 210 less prone to rust. In addition, the first housing 10 and the second housing 20 are detachably connected, which is convenient for disassembly and assembly and has low cost.

[0040] Specifically, the first housing 10 and the second housing 20 can be snap-fitted together, and a sealing rubber ring 35 can be used to seal the connection between the first housing 10 and the second housing 20. The first housing 10 and the second housing 20 are sealed and connected, the first accommodation space 101 and the second accommodation space 202 are connected, the first terminal 110 and the second terminal 210 are electrically connected in the second accommodation space 202, and the first housing 10 and the second housing 20 can isolate the connection between the first terminal 110 and the second terminal 210 from the external environment.

[0041] One end of the second terminal 210 is connected to the first terminal 110, and the end of the second terminal 210 away from the first terminal 110 can be connected to a wire and electrically connected to an electrical device of the vehicle 1000 through the wire. The first sealing member 31 can wrap the wire inserted into the second accommodating space 202, connect the inner wall of the second accommodating space 202, and seal the inserted wire segment in the second housing 20. The first sealing member 31 can be a component with good insulation and airtightness, such as a silicone ring, a rubber sleeve, etc., which can be set outside the wire and cover the part of the wire inserted into the second accommodating space 202.

[0042] See also Figure 2 and Figure 3 In some embodiments, the first terminal 110 partially extends out of the first accommodating space 101 , and the first terminal 110 is used to be at least partially inserted into the box body 201 along with the first shell 10 , and the first shell 10 is sealed and connected to the box body 201 .

[0043] In this way, the first housing 10 is sealedly connected to the box 201 , and when the first terminal 110 is installed on the box 201 along with the first housing 10 , the first terminal 110 and the interior of the box 201 can be protected from water and dust.

[0044] Specifically, the portion of the first terminal 110 inserted into the box 201 can be connected to the circuit in the box 201 by gluing, and then sealed with the box 201 by insert injection molding. The waterproof and dustproof performance of the sealed connection between the first housing 10 and the first terminal 110 and the box 201 can reach IP68 level and IP6K9K level.

[0045] See also Figure 2-Figure 4 , Figure 3 1 is a perspective schematic diagram of the structure of the connector 100 in some embodiments of the present application in the first housing 10. In some embodiments, the first housing 10 includes a first mounting portion 11 and a second mounting portion 12 connected to the first mounting portion 11, the first mounting portion 11 and the second mounting portion 12 together form a first accommodating space 101, and the first terminal 110 partially extends out of the second mounting portion 12.

[0046] A step surface 13 is formed at the connection between the first mounting portion 11 and the second mounting portion 12 . The connector 100 includes a second sealing member 32 disposed on the step surface 13 and surrounding the second mounting portion 12 . The second sealing member 32 is used for sealingly connecting with the outer surface of the box body 201 .

[0047] Thus, by forming a step surface 13 between the first mounting portion 11 and the second mounting portion 12, the first housing 10 is easily inserted into the box body 201. By surrounding the second mounting portion 12 on the step surface 13 with the second sealing member 32, the sealing property of the connection between the first housing 10 and the box body 201 can be enhanced, and the probability of corrosion of the first terminal 110 can be reduced.

[0048] Specifically, the first mounting portion 11 and the second mounting portion 12 may both be hollow tubular or columnar structures, the first mounting portion 11 and the second mounting portion 12 may be coaxial, and the first mounting portion 11 may be connected to the upper part of the second mounting portion 12 along the axial direction of the first mounting portion 11 and the second mounting portion 12. The outer wall of the first mounting portion 11 may extend beyond the second mounting portion 12 in the lateral direction to form a step surface 13, and the inner wall position of the first mounting portion 11 may be close to the inner wall position of the second mounting portion 12. The first housing 10 is inserted into the box body 201, and is engaged with the outer surface of the box body 201 through the step surface 13. The second mounting portion 12 may be the part of the first housing 10 inserted into the box body 201, and the first mounting portion 11 may be exposed outside the box body 201. It should be noted that the first mounting portion 11 and the second mounting portion 12 are parts of different shapes or sizes on the first housing 10, and the first mounting portion 11 and the second mounting portion 12 may be an integral structure formed in one piece.

[0049] The second sealing member 32 may be a silicone ring, a rubber sleeve or other element with certain elasticity and insulation. The second sealing member 32 may be sleeved outside the second mounting portion 12 and fit on the step surface 13. When the first housing 10 is inserted into the box body 201, the second sealing member 32 seals and connects the step surface 13 and the outer surface of the box body 201, thereby ensuring that the connection between the first terminal 110 and the box body 201 is waterproof and dustproof, thereby preventing the first terminal 110 from rusting.

[0050] Please continue reading Figure 2-Figure 4 In some embodiments, a third sealant 33 is disposed between the first terminal 110 and the inner wall of the first accommodating space 101 , and the third sealant 33 seals the gap between the first terminal 110 and the inner wall of the first accommodating space 101 .

[0051] In this way, the gap between the first terminal 110 and the inner wall of the first accommodating space 101 is sealed by the third sealing member 33 , so that the first terminal 110 can be further prevented from being corroded.

[0052] Specifically, the first terminal 110 is partially accommodated in the first accommodation space 101, and the shapes of the first terminal 110 and the first accommodation space 101 are not completely consistent. There is a certain gap between the first terminal 110 and the inner wall of the first accommodation space 101, and the gap is relatively small and the shape is relatively irregular. The third sealing member 33 can be a sealant, or a rubber sleeve with a certain elasticity, so that it can adapt to the shape of the gap. The third sealing member 33 can also be formed by pouring liquid sealant into the gap between the first terminal 110 and the inner wall of the first accommodation space 101 by pouring, and then solidifying. The sealant can fill the gap between the first terminal 110 and the inner wall of the first mounting portion 11 and the second mounting portion 12, and discharge the air in the gap. The third sealing member 33 fits the outer surface of the first terminal 110 and the inner surface of the first mounting portion 11 and the second mounting portion 12. On the one hand, it can strengthen the waterproof, dustproof and corrosion-resistant protection of the first housing 10 to the first terminal 110, and on the other hand, it can also bond and fix the first terminal 110 to the inner wall of the first housing 10.

[0053] See also Figure 2 , Figure 5 and Figure 6 , Figure 5 1 is a perspective schematic diagram of the partial structure of the connector 100 in the second housing 20 of some embodiments of the present application. In some embodiments, the second housing 20 includes a first connection portion 21 and a second connection portion 22 connected and communicating with the first connection portion 21, the first connection portion 21 and the second connection portion 22 form an angle in the axial direction, the first connection portion 21 forms a second accommodating space 202, the second connection portion 22 is rotatably inserted in the first housing 10, and the end face of the second connection portion 22 is sealed and connected to the first housing 10.

[0054] In this way, the first connection part 21 and the second connection part 22 form an axial angle to facilitate the assembly of the first shell 10 and the second shell 20. The second connection part 22 can rotate relative to the first shell 10, which is beneficial for the connector 100 to adapt to the vehicle 1000.

[0055] Specifically, the first connection part 21 and the second connection part 22 can be connected as an integral part and can be integrally formed. The first connection part 21 can be in the shape of a hollow column, and the inner wall of the first connection part 21 and the inner contour of the first connection part 21 define the second accommodating space 202. The first connection part 21 can form an opening at one end to accommodate the insertion of the wire, and the second connection part 22 can be formed on a side surface of the first connection part 21, located at an end away from the connection between the wire and the second terminal 210, and extending in a direction different from the axial direction of the first connection part 21.

[0056] The axial direction of the first connection part 21 can be perpendicular to the axial direction of the second connection part 22, the second connection part 22 can be inserted into the first accommodating space 101, and the outer wall of the second connection part 22 is matched with the inner wall of the first mounting part 11. The second connection part 22 can be coaxial with the first mounting part 11, and the second connection part 22 can rotate around the axial direction of the first mounting part 11, and the rotation angle range of the second connection part 22 relative to the first housing 10 can be 0° to 360°.

[0057] See also Figure 2 In some embodiments, the second connection portion 22 is disposed around the first terminal 110 .

[0058] In this way, the second connecting portion 22 can be easily rotated relative to the first housing 10 .

[0059] Specifically, the first housing 10 and the second housing 20 are installed together, and the second connection portion 22 and the first mounting portion 11 are inserted and nested together, and the first accommodation space 101 and the second accommodation space 202 are connected. A sealing rubber ring 35 can be provided on the connection surface where the first mounting portion 11 and the second connection port are inserted for sealing. The first terminal 110 is provided in the second accommodation space 202 and can be coaxial with the first mounting portion 11 and the second mounting portion 12.

[0060] The first terminal 110 can partially extend from the first accommodating space 101 into the second accommodating space 202, facing the inner wall of the second connecting portion 22. The second connecting portion 22 can be a thin-walled column, inserted into the first accommodating space 101, and can rotate along the axial direction of the second terminal 210. The second connecting portion 22 can drive the second housing 20 to rotate relative to the first housing 10 around the axial direction of the second terminal 210.

[0061] See also Figure 2 and Figure 6 In some embodiments, it is characterized in that the connector 100 includes an end cover 23 arranged at an end of the first connection part 21 away from the second connection part 22, and the first sealing member 31 is arranged in a port 231 of the first connection part 21 away from the second connection part 22.

[0062] Thus, by covering the port 231 of the first connection part 21 away from the second connection part 22 with the end cap 23, a certain protection can be formed for the second terminal 210 when no wire is inserted into the second housing 20, and a certain support can be provided when the wire is inserted.

[0063] Specifically, the first housing 10 is connected to the second housing 20 at the second connection portion 22, and a port 231 is provided at the end of the first connection portion 21 away from the second connection portion 22, and the port 231 can accommodate a wire passing through the port 231 and extending into the second accommodation space 202. The end cover 23 is sleeved outside the port 231, and a first sealing member 31 is provided inside the port 231, thereby providing protection and support for the connection between the wire inserted into the second accommodation space 202 and the second terminal 210.

[0064] like Figure 8 As shown, the end of the second terminal 210 near the port 231 may be in the shape of a cylinder or a hollow column, and may be crimped together with the wire inserted into the second housing 20 by the wire crimping device 24. Figure 7 As shown, one end of the second terminal 210 close to the port 231 may also be flat, and may be adapted to fit an aluminum wire, and connected to the aluminum wire by ultrasonic welding.

[0065] Please refer again Figure 2 and Figure 6 In some embodiments, the second terminal 210 is formed with a mounting hole 211 , and the connector 100 includes a fastener 25 , which is passed through the mounting hole 211 and partially inserted into the first terminal 110 to be fastened to the first terminal 110 .

[0066] In this way, the first terminal 110 and the second terminal 210 are fastened and connected by the fastener 25, and the connection is more stable.

[0067] Specifically, the second terminal 210 is installed in the second accommodation space 202, with one end close to the port 231 for connection with the wire. The end of the second terminal 210 away from the port 231 can be in the shape of a flat sheet, and a mounting hole 211 is formed in the flat sheet part, and the mounting hole 211 faces the extension direction of the second connecting portion 22, and is used to connect the second terminal 210. The fastener 25 can be a bolt, a screw rod or the like, and the fastener 25 can be in the same axial direction as the second connecting portion 22, pass through the mounting hole 211 and partially extend into the first accommodation space 101, and the portion of the fastener 25 extending into the first accommodation space 101 can be formed with a thread. The portion of the first terminal 110 located in the first accommodation space 101 can form a screw hole, and the first terminal 110 and the fastener 25 can be fastened and connected by screw thread matching.

[0068] It should be noted that the first terminal 110 and the second terminal 210 are locked and connected by the fastener 25. When the fastener 25 is not locked, the second terminal 210 and the second connecting portion 22 can rotate along the axial direction of the first terminal 110. When the fastener 25 is locked, the second terminal 210 is firmly connected to the first terminal 110, and the first shell 10 and the second shell 20 can remain relatively still.

[0069] The sealing connection between the first shell 10 and the second shell 20 and the provision of the second sealing member 32 and the third sealing member 33 can also reduce the corrosion of the fastener 25 .

[0070] Please continue reading Figure 2 and Figure 6 In some embodiments, the second shell 20 is provided with an installation window 261 , the fastener 25 is directly opposite to the installation window 261 , and the connector 100 includes a protective cover 26 detachably connected to the second shell 20 and closing the installation window 261 .

[0071] In this way, the fastener 25 can be installed through the installation window 261 to connect the first terminal 110 and the second terminal 210 , and the installation window 261 can be closed by the protective cover 26 to ensure the sealing of the second housing 20 and prevent water and dust.

[0072] Specifically, the installation window 261 can be formed on the side opposite to the second connection portion 22, facing the fastener 25. The installation window 261 can be formed as a circular or elliptical window to effectively utilize the housing surface area of ​​the first connection portion 21. The protective cover 26 is detachably connected to the second housing 20. When the protective cover is removed, the fastener 25 can be installed, inspected, and removed through the installation window 261, and the connection between the first terminal 110 and the second terminal 210 can be observed and adjusted.

[0073] The protective cover 26 completely covers the installation window 261, and the protective cover 26 may have a part of the cover wall covering the outer wall of the first connecting portion 21. A fourth sealing member 34 may be provided inside the protective cover 26, and the fourth sealing member 34 may be a rubber sleeve or a rubber ring, which is used to seal and connect the protective cover 26 and the first connecting portion 21. The fourth sealing member 34 may be sleeved on one end of the fastener 25 located in the second accommodating space 202, and abut against the inner wall of the protective cover 26 and the first connecting portion 21.

[0074] See also Figure 2 and Figure 5 In some embodiments, the connector 100 further includes a flexible member 27 connecting the protective cover 26 and the second shell 20 .

[0075] In this way, the protective cover 26 and the second shell 20 are connected by the flexible member 27, which facilitates the assembly of the entire vehicle and prevents the protective cover 26 from being lost.

[0076] Specifically, a through hole 271 may be formed on the protective cover 26, and the flexible member 27 may pass through the through hole 271 and be fixed at the through hole 271. The flexible member 27 may form a collar and may be sleeved outside the end cover 23 and the second shell 20. The length of the flexible member 27 may be set to form a collar sleeved outside the end cover 23 and the second shell 20, so that the protective cover 26 and the second shell 20 can be tightly sleeved together. The flexible member 27 may also be fixed to the protective cover 26 at one end and wrapped around the protective cover 26 and the second shell 20 at the other end to tie the protective cover 26 and the second shell 20 together.

[0077] The flexible member 27 may be a plastic rope, such as a nylon rope, a polypropylene rope, a polyester rope, etc. The flexible member 27 may have a certain elasticity, so that it can be sleeved outside the protective cover 26 and the second shell 20, and can be removed from the protective cover 26 and the second shell 20, so that the protective cover 26 can be detachably connected to the second shell 20.
