[0041] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0044] See Figures 1-3This application provides an electrical connector, including a plug 100, a socket 200, and a latch 300. The latch 300 includes a snap-fit ​​groove 301, and the socket 200 includes a snap-fit ​​portion 201 and a base 202. The snap-fit ​​groove 301 and the snap-fit ​​portion 201 are slidably connected. The inner wall of the latch 300 is provided with a mounting groove 302. The end of the plug 100 is provided with a first protrusion 304, which cooperates with the mounting groove 302. The outer wall of the latch 300 is provided with a cantilever 303, and the end of the cantilever 303 is provided with a second protrusion. The outer wall of the snap-fit ​​portion 201 is provided with a plurality of grooves 203 that cooperate with the second protrusion.

[0045] Specifically, the latch 300 and the socket 200 are initially fixed through a sliding connection of the snap-fit ​​groove 301 and the snap-fit ​​part 201. Meanwhile, the plug 100 and the latch 300 are connected by the cooperation of the first protrusion 304 and the mounting groove 302, enhancing connection stability. Furthermore, the second protrusion of the cantilever 303 on the outer wall of the latch 300 cooperates with the groove 203 on the outer wall of the socket 200, providing a foolproof function for multi-angle insertion.

[0046] Specifically, the snap-fit ​​part 201 and the seat 202 are an integral structure.

[0047] In use, when the plug 100 is inserted into the socket 200, the first protrusion 304 engages with the mounting groove 302 of the latch 300 to ensure the correct relative position of the plug 100 and the socket 200. Subsequently, the snap-fit ​​groove 301 of the latch 300 slides into contact with the snap-fit ​​part 201 of the socket 200, achieving initial fixation. The second protrusion on the cantilever 303 engages with the groove 203 on the outer wall of the socket 200 to further ensure that the connector can only be correctly mated at a specific angle, thereby improving the stability and safety of the electrical connector during mating and achieving a foolproof function for multi-angle free mating.

[0048] It should be noted that the shape of the latch 300 is adapted to the interface shape of the electrical connector. For example, when the interface is round, square, or regular polygonal, the shape of the latch 300 is round, square, or regular polygonal, respectively.

[0049] In summary, the electrical connector provided by this utility model, when in use, has the snap-fit ​​groove 301 snap-fitted into the snap-fit ​​part 201, and the second protrusion of the cantilever 303 snap-fitted into a groove 203, forming a relative fixation between the latch 300 and the socket 200. The first protrusion 304 cooperates with the mounting groove 302, forming a relative fixation between the latch 300 and the plug 100. This arrangement allows the plug 100 and the socket 200 to be freely inserted at multiple angles in the circumferential direction, realizing wire exit at any angle in the 360-degree circumferential direction. At the same time, the cooperation between the first protrusion 304 and the mounting groove 302 realizes the foolproof function of the electrical connector, improving the safety of the electrical connector during use.

[0050] To optimize the above technical solution, the snap-fit ​​part 201 and the seat 202 form a closed ring. The larger the distribution area of ​​the snap-fit ​​part 201 and the groove 203 within the ring, the larger the rotation angle of the locking component can be, that is, the larger the range of foolproof protection. The latch 300 is a non-closed ring, and the length of the latch 300 is less than the length of the snap-fit ​​part 201.

[0051] Specifically, the length of the latch 300 is less than the length of the latching portion 201, allowing the latch 300 to move freely along the latching portion 201. The multi-angle rotation effect between the latch 300 and the socket 200 matches the position and structure of the second protrusion. Specifically, because the latch 300 needs to move on the latching portion 201, and the second protrusion needs to move within the distribution area of ​​the groove 203 to meet the multi-angle insertion requirements of the plug 100 and the socket 200, the larger the distribution area of ​​the latching portion 201 and the groove 203, the greater the range of movement of the latch 300 and the second protrusion, and the more insertion angles can be achieved. At the same time, installation space for the base 202 needs to be reserved. Therefore, it is preferable that the distribution area of ​​the latching portion 201 is greater than half the size of the ring, and the distribution area of ​​the groove 203 is greater than half the size of the ring. Under the premise of meeting the above structural conditions, the maximum rotation angle of the latch 300 can be increased or decreased with the increase or decrease of the distribution area of ​​the latching portion 201 and the groove 203.

[0052] The closed ring formed by the snap-fit ​​part 201 and the base 202, as well as the non-closed ring design of the snap-fit ​​part 201, the groove 203, and the latch 300, optimize the structure of the socket 200 and the latch 300, ensuring that they can cooperate more stably. This allows the connector to achieve stable mating at multiple angles, enhances the structural stability of the connector, and improves the flexibility and safety of multi-angle mating.

[0053] In some embodiments, a limiting groove 205 is radially formed on the outer wall of the snap-fit ​​portion 201, and a limiting block 305 is provided on the inner wall of the snap-fit ​​groove 301. The limiting block 305 is slidably connected to the limiting groove 205, and the limiting block 305 is used to limit the movement of the latch 300 along the axial direction.

[0054] Specifically, the limiting groove 205 is a continuous groove, that is, the limiting block 305 can move against the outer wall of the snap-fit ​​part 201.

[0055] During the insertion of the plug 100 into the socket 200, the latching groove 301 of the latch 300 slides into contact with the latching part 201 of the socket 200, while the limiting block 305 also slides into contact with the limiting groove 205. The setting of the limiting block 305 on the inner wall of the latching groove 301 restricts the latch 300 in the axial direction, preventing it from moving freely.

[0056] This solution, through the cooperation of the limiting block 305 and the limiting groove 205, restricts the axial movement of the locking buckle 300, ensuring the stability of the connector during the docking process, preventing connection failure caused by the movement of the locking buckle 300, and improving the safety of the electrical connector during use.

[0057] In other embodiments, the outer wall of the snap-fit ​​portion 201 is provided with a limiting groove 205 in the radial direction, the outer wall of the latch 300 is L-shaped, the cantilever 303 is disposed on the vertical part of the latch 300, the horizontal part of the latch 300 is snapped into the interior of the limiting groove 205, and the horizontal part of the latch 300 is used to limit the axial movement of the latch 300.

[0058] Specifically, the design of the L-shaped latch 300 enables the latch 300 to have stronger resistance to deformation when subjected to external forces, while the limiting groove 205 serves to constrain the movement of the latch 300.

[0059] During use, as the plug 100 is inserted into the socket 200, the horizontal part of the L-shaped latch 300 engages within the limiting groove 205 on the outer wall of the socket 200. This design constrains the latch 300 in the axial direction, preventing it from moving freely. Simultaneously, the vertical part of the L-shaped latch 300 slides into the engaging portion 201 of the socket 200, ensuring a stable connection for the connector.

[0060] The L-shaped latch 300 and the limiting groove 205 work together to ensure that the connector remains tightly connected even when subjected to external force, making it less likely to fall off or loosen, thereby improving the connection stability and safety of the connector.

[0061] See Figure 4 and Figure 5 In order to optimize the above technical solution, the outer wall of the latch 300 is provided with a U-shaped groove, and the end of the cantilever 303 is suspended inside the U-shaped groove. The cantilever 303 includes an elastic arm.

[0062] Specifically, the U-shaped groove provides sufficient space for the cantilever 303 to elastically deform, and the elastic cantilever 303 can adaptively adjust its position to ensure accurate docking with the socket 200.

[0063] During use, as the plug 100 is inserted into the socket 200, the second protrusion guides the insertion into the groove 203. The end of the cantilever 303 engages with the groove 203 on the outer wall of the socket 200. Because the cantilever 303 includes an elastic arm made of elastic material, it can adaptively adjust its position to ensure accurate alignment with the groove 203, achieving multi-angle positioning. Simultaneously, the U-shaped groove design and elastic design allow the cantilever 303 to elastically deform when subjected to external forces, thereby absorbing some of the impact force, protecting the connector from damage, and extending the service life of the electrical connector.

[0064] Specifically, the preferred elastic arm is made of PA66+GF plastic material.

[0065] To optimize the above technical solution, a boss 204 is arranged radially on the outer wall of the snap-fit ​​part 201. The boss 204 is used to support the outer wall of the latch 300. The length of the outer wall of the latch 300 is less than the length of the inner wall of the latch 300.

[0066] Specifically, the design of the boss 204 provides support for the latch 300, ensuring that the connector remains stable during the docking process. This allows the latch 300 to have stronger support when subjected to external forces, making it less prone to deformation or detachment due to uneven force.

[0067] Specifically, by making the length of the outer wall of the latch 300 shorter than the length of the inner wall of the latch 300, it is possible to meet the engagement requirements of the second protrusion and the groove 203, and ensure that the outer and inner walls of the latch 300 can effectively clamp the latching part 201, while reducing the material used in the latch 300 and lowering the production cost.

[0068] During use, as the plug 100 is inserted into the socket 200, the boss 204 acts as a guide, ensuring accurate alignment between the plug 100 and the socket 200. At the same time, the bottom of the latch 300 contacts and is supported by the boss 204, further improving the stability and safety of the connector.

[0069] To optimize the above technical solution, the second protrusion includes a polygonal structure or a circular structure.

[0070] Specifically, the first protrusion 304 includes a polygonal structure or a circular structure.

[0071] Specifically, the shape of the second protrusion can be adapted to the shape of the groove 203.

[0072] Specifically, the cross-sectional shape of the first protrusion 304 and the second protrusion is polygonal or circular.

[0073] This design utilizes a polygonal or circular second protrusion to provide a more reliable foolproof mechanism. This design aims to ensure that the connectors connect accurately during mating, avoiding power transmission problems caused by incorrect mating of the plug 100 and socket 200.

[0074] A polygonal or circular second protrusion is cleverly designed on the outer wall of the latch 300, while the outer wall of the socket 200 is correspondingly provided with multiple grooves 203 that match the shape of the second protrusion. When the plug 100 is fully inserted into the socket 200, the second protrusion will accurately engage with the corresponding groove 203, forming a stable connection, thereby ensuring the correct mating between the plug 100 and the socket 200 and effectively preventing power transmission failures caused by incorrect mating.

[0075] It is worth noting that the engagement of the second protrusion with the groove 203 does not depend on the insertion angle of the plug 100, but rather on the relative position between the plug 100 and the socket 200. Therefore, regardless of how the plug 100 approaches the socket 200 (in the vertical direction), as long as the plug 100 can be fully inserted into the socket 200, the second protrusion will engage with the groove 203 to achieve the foolproof function.

[0076] To optimize the above technical solution, the number of limiting blocks 305 is two, and they are respectively arranged at both ends of the inner wall of the snap-fit ​​groove 301.

[0077] Specifically, the number of limit blocks 305 can be two or more to improve the limiting effect. Increasing the number of limit blocks 305 can improve the stability of the latch 300 in axial movement.

[0078] During use, as the plug 100 is inserted into the socket 200, the two limiting blocks 305 slide against the limiting grooves 205 on the outer wall of the socket 200. Since the two limiting blocks 305 are respectively arranged at both ends of the inner wall of the snap-fit ​​groove 301, they can jointly constrain the movement of the latch 300 in the axial direction, so that the connector can maintain a stable connection when subjected to external force.

[0079] To optimize the above technical solution, the top of the latch 300 is provided with an opening 306, the position of which corresponds to the position of the limiting block 305.

[0080] Specifically, the limiting block 305 is disposed on the inner wall of the snap-fit ​​groove 301, and the opening 306 is disposed on the bottom of the snap-fit ​​groove 301. The position of the opening 306 corresponding to the position of the limiting block 305 means that when the latch 300 is in such a position... Figure 4 When the position is shown, the latch 300 is cut vertically, and the opening 306 and the limiting block 305 are at the same cross section of the snap-fit ​​groove 301.

[0081] Specifically, the design of the opening 306 allows users to intuitively see whether the limiting block 305 is correctly matched with the limiting groove 205, thereby ensuring the correct connection of the connector. At the same time, based on the product's mold production process, the design of the opening 306 is beneficial to the simplification and strength of the mold.

[0082] See Figure 6To optimize the above technical solution, the socket 200 includes an unlocking component 400, which is arranged inside the base 202. The unlocking component 400 includes a buckle 401 and a spring 402. The base 202 has a placement groove, and the buckle 401 is arranged inside the placement groove and can move along the placement groove. A limiting hole is provided on the side of the placement groove away from the locking part 201. A limiting protrusion 403 that cooperates with the limiting hole is provided on the outer surface of the buckle 401. The first end of the spring 402 abuts against the bottom of the placement groove, and its second end is connected to the outer surface of the buckle 401. An arc-shaped rib is arranged on the side of the buckle 401 near the locking part 201. The arc-shaped rib is used to lock the first protrusion 304.

[0083] Specifically, the unlocking component 400 is used to enable easy unlocking and disassembly of the connector.

[0084] Specifically, when the plug 100 is cylindrical, the placement groove is located on the side away from the latch 300 and close to the first protrusion 304. The extension direction of the placement groove is the tangential direction when the first protrusion 304 rotates. When the operator presses in the latch 401, the arc-shaped rib avoids the first protrusion 304, the spring 402 pops out the latch 401, and the arc-shaped rib is engaged between two adjacent first protrusions 304.

[0085] When the connector needs to be unlocked, the user can release the connection between the plug 100 and the socket 200 by operating the latch 401 in the unlocking component 400. Initially, the spring 402 is slightly compressed or not compressed, and the limiting protrusion 403 is engaged with the outward end of the limiting hole to prevent the latch 401 from falling out of the placement groove. The arc-shaped rib is engaged between two adjacent first protrusions 304. When unlocking is required, the user presses the latch 401 inward, and the latch 401 moves along the placement groove until the limiting protrusion 403 is engaged with the inward end of the limiting hole. The spring 402 is in a compressed state, and at the same time, the arc-shaped rib disengages from between the two adjacent first protrusions 304, no longer engaging the plug 100, thus unlocking the plug 100 from the socket 200.

[0086] During the unlocking process, the user only needs to press the latch 401 to release the connector's locked state, enabling convenient unlocking and disassembly, making connector maintenance and replacement simpler and more convenient.
