[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides a Type-C connector with anti-misinsertion function, such as Figures 1 to 6 As shown, it includes a Type-C male connector 1 and a Type-C female connector 2. The left end of the Type-C male connector 1 is movably inserted into the Type-C female connector 2. Both the Type-C male connector 1 and the Type-C female connector 2 have connecting wires 3 on opposite ends. A sliding locking sleeve 4 is movably sleeved on the Type-C male connector 1. A positioning sleeve 5 is fixedly installed on the Type-C female connector 2. The left side of the sliding locking sleeve 4 fits against the right side of the positioning sleeve 5. Two sets of guide grooves 6 are opened on the upper and lower sides of the Type-C male connector 1. A return spring 7 is installed in each of the four sets of guide grooves 6. The side of the sliding locking sleeve 4 that fits against the surface of the Type-C male connector 1 is movably inserted into the four sets of guide grooves 6. Anti-misinsertion components are provided on the sliding locking sleeve 4 and the positioning sleeve 5.

[0026] When the Type-C male connector 1 and the Type-C female connector 2 are mated, and the sliding locking sleeve 4 begins to contact the positioning sleeve 5, the sliding locking sleeve 4 will slide to the left along the surface of the Type-C male connector 1 under the action of external force. At the same time, the anti-misfit components on the front and rear sides of the sliding locking sleeve 4 will gradually insert into the front and rear ends of the positioning sleeve 5 under the action of external force. Even under the interference of external force, the correct connection of the Type-C male connector 1 and the Type-C female connector 2 can be guaranteed, effectively avoiding the problem of traditional Type-C connectors being easily reversed or misfitted.

[0027] Four sets of conductive pins 8 are fixedly installed on the left side of the Type-C male connector 1, and the four sets of conductive pins 8 are movably inserted into the Type-C female connector 2.

[0028] The four sets of conductive pins 8 further enhance the connection stability between the Type-C male connector 1 and the Type-C female connector 2. When the Type-C male connector 1 is inserted into the Type-C female connector 2, the four sets of conductive pins 8 can slide along the inner wall of the Type-C female connector 2 until it is fully inserted. This process not only plays a guiding role, but also effectively prevents the Type-C male connector 1 from shaking inside the Type-C female connector 2, thus improving the stability of the connector.

[0029] Four sets of anti-misalignment protrusions 9 are fixedly installed on the right side of both ends of the sliding lock sleeve 4. The four sets of anti-misalignment protrusions 9 are symmetrically arranged. Four sets of anti-misalignment grooves 10 are opened in the right end of the positioning sleeve 5. The four sets of anti-misalignment protrusions 9 are movably inserted into the four sets of anti-misalignment grooves 10. Locking buckles 11 are rotatably installed on both the front and rear sides of the sliding lock sleeve 4. Torsion springs 12 are installed at the connection between the two sets of locking buckles 11 and the sliding lock sleeve 4. Buckle grooves 13 are opened on the opposite side of the four sets of anti-misalignment protrusions 9 and in the front and rear ends of the two sets of positioning sleeves 5.

[0030] During the connection process, when the sliding lock sleeve 4 slides to the left along the Type-C male connector 1 to a certain extent, the four sets of anti-misalignment protrusions 9 will be inserted into the four sets of anti-misalignment grooves 10. At this time, the protruding ends of the two sets of locking buckles 11 are inserted into the buckle grooves 13 at the front and rear ends of the positioning sleeve 5, thereby realizing the locking between the sliding lock sleeve 4 and the positioning sleeve 5, further enhancing the stability of the connector.

[0031] The cross-section of the four sets of error-proof bumps 9 is triangular, and the opposite ends of the four sets of error-proof bumps 9 are acute angles.

[0032] This design allows the anti-misalignment protrusion 9 to enter the anti-misalignment groove 10 more smoothly. The acute-angled design makes it easier for the locking buckle 11 to snap into the buckle groove 13 to achieve the locking function. At the same time, the triangular cross-section design can also increase the contact area between the anti-misalignment protrusion 9 and the anti-misalignment groove 10, and improve the stability of the connection.

[0033] Both sets of locking buckles 11 are L-shaped, and the protruding ends of the two sets of locking buckles 11 are inserted into the buckle grooves 13 at the front and rear ends of the positioning sleeve 5.

[0034] When the connector needs to be disassembled, simply press the two sets of locking buckles 11 in the opposite direction to disengage their protruding ends from the buckle grooves 13. This will easily separate the sliding lock sleeve 4 from the positioning sleeve 5, allowing the Type-C male connector 1 to be pulled out of the Type-C female connector 2. The entire disassembly process is simple and quick, greatly improving efficiency.

[0035] The left ends of the four sets of return springs 7 are fixedly connected to the inner wall of the left end of the guide groove 6, and the right ends of the four sets of return springs 7 are fixedly connected to one end of the sliding lock sleeve 4 inserted into the four sets of guide grooves 6.

[0036] The four sets of return springs 7 serve as guides and resets, ensuring that the sliding sleeve 4 remains stable when sliding along the surface of the Type-C male connector 1 and does not deviate from the track, further improving the accuracy and stability of the connection.

[0037] Both the mating surfaces of Type-C male connector 1 and Type-C female connector 2 are provided with guide bevels.

[0038] The guide bevel allows for smoother insertion of the Type-C male connector 1 and Type-C female connector 2 during the mating process. Even if there is some deviation, the guide bevel can automatically correct the direction, ensuring a smooth connection. At the same time, the guide bevel can effectively reduce friction during mating, making it easier to insert and remove the connector and improving the user experience.

[0039] An insulating baffle is provided at the left end of conductive pin 8, which can effectively isolate current and prevent short circuits caused by misoperation, further improving the safety of the connector.

[0040] In use, this invention connects the Type-C male connector 1 and the Type-C female connector 2. The sliding locking sleeve 4 is movably fitted onto the Type-C male connector 1, and the positioning sleeve 5 is fixedly installed on the Type-C female connector 2. This allows the Type-C male connector 1 and the Type-C female connector 2 to automatically correct their orientation during insertion, ensuring proper connection. Simultaneously, the four sets of conductive pins 8 slide along the inner wall of the Type-C female connector 2, acting as a guide and preventing the Type-C male connector 1 from wobbling inside the Type-C female connector 2. When the sliding locking sleeve 4 and the positioning sleeve 5 begin to contact, the sliding locking sleeve 4, under the action of external force, will move to the left along the surface of the Type-C male connector 1. When the connector slides, the four sets of anti-misalignment protrusions 9 are precisely inserted into the four sets of anti-misalignment grooves 10. Subsequently, the protruding ends of the two sets of locking buckles 11 are inserted into the buckle grooves 13 at both ends of the positioning sleeve 5, realizing the locking between the sliding locking sleeve 4 and the positioning sleeve 5. Even under external force interference, the correct connection between the Type-C male connector 1 and the Type-C female connector 2 can be guaranteed. When it is necessary to disassemble the connector, press the two sets of locking buckles 11 in the opposite direction to make their protruding ends come out from the buckle grooves 13, so that the sliding locking sleeve 4 can be separated from the positioning sleeve 5, and then the Type-C male connector 1 can be pulled out from the Type-C female connector 2. The entire connector is scientifically and rationally designed, safe and convenient to use, and has high practicality.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
