[0020] The present invention will now be described in detail with reference to the accompanying drawings.

[0021] like Figures 1 to 3 As shown, this utility model discloses a rotary snap connector, including a male end 1 and a female end 2, which are inserted into each other. A first conductive element 3 is provided inside the male end 1; a second conductive element 4 is provided inside the female end 2. The second conductive element 4 has an elastic structure, and the first conductive element 3 is inserted into the second conductive element 4 and abuts against the elastic structure. The elastic structure ensures a continuous and stable contact pressure between the first conductive element 3 and the second conductive element 4, thereby improving the conductive contact reliability of the connector and compensating for the mating tolerance.

[0022] A locking structure is provided between male terminal 1 and female terminal 2. The rotary locking structure 5 can firmly lock male terminal 1 and female terminal 2, effectively preventing the connector from accidentally loosening under vibration and other environments, and simplifies the connection operation, realizing quick insertion and removal.

[0023] The user first aligns the male end 1 with the female end 2 and pushes it axially. As the male end 1 and female end 2 are inserted, the first conductive element 3 enters the interior of the second conductive element 4 and begins to contact the elastic structure. Further pushing in the first conductive element 3 compresses the elastic structure, creating a stable contact. This ensures a reliable and stable electrical connection between the first conductive element 3 and the second conductive element 4 through the elastic structure, overcoming the influence of fit tolerances. After the first conductive element 3 and the second conductive element 4 are fully inserted, the user rotates either the male end 1 or the female end 2. The rotation drives the rotation locking structure 5 to engage or latch, thus achieving a mechanical lock between the male end 1 and the female end 2. This ensures the secure connection between the male end 1 and the female end 2 and prevents accidental separation under vibration or tension. To disconnect the male end 1 and the female end 2, simply rotate in the opposite direction to unlock, and then pull it out axially.

[0024] like Figure 2 As shown, in this embodiment, the first conductive member 3 is provided with a first limiting part 31, and the second conductive member 4 is provided with a second limiting part 41; The male end 1 is provided with a first outer shell 11, and the female end 2 is provided with a second outer shell 21. Both the first outer shell 11 and the second outer shell 21 are provided with a rear cover 6, and the rear cover 6 is fixed to the first outer shell 11 and the second outer shell 21 respectively. The rear cover 6 is provided with claws 61 that respectively abut against the first limiting part 31 and the second limiting part 41. The rear cover 6 and the claws 61 are integrally set, which facilitates the assembly and maintenance of the connector.

[0025] By having the claw 61 abut against the first limiting part 31 and the second limiting part 41, the first conductive element 3 and the second conductive element 4 are effectively axially limited and fixed, ensuring the installation stability and reliability of the conductive elements inside the male end 1 and the female end 2, and preventing them from loosening or falling out when inserted, removed or subjected to force.

[0026] like Figure 1 As shown, both the first outer shell 11 and the second outer shell 21 in this embodiment are provided with locking holes 22, and the rear cover 6 is provided with a locking block 62 that engages with the locking holes 22. Utilizing the locking action between the locking block 62 and the locking holes 22, a quick and reliable connection is achieved between the rear cover 6 and the first outer shell 11 and the second outer shell 21. This locking structure greatly simplifies the assembly process, improves the production efficiency of the connector, and provides convenience for the subsequent maintenance and repair of the connector.

[0027] like Figure 2 As shown, in this embodiment, a first blocking part 12 is provided inside the first outer shell 11, and the end of the first limiting part 31 facing away from the claw 61 abuts against the first blocking part 12. This provides a second axial limiting for the first conductive element 3.

[0028] By combining the contact of the claw 61 with the other end of the first limiting part 31, a comprehensive, bidirectional axial fixation of the first conductive element 3 is achieved. This dual limiting effectively prevents the first conductive element 3 from axial displacement when subjected to insertion force, extraction force, or impact, greatly improving the stability of the first conductive element 3 installed inside the first housing 11 and the reliability of the connector.

[0029] like Figure 2 As shown, in this embodiment, a second blocking portion 23 is provided inside the second outer casing 21, and the end of the second conductive member 4 away from the second limiting portion 41 abuts against the second blocking portion 23. This provides a second axial limiting for the second conductive member 4.

[0030] The claws 61 on the rear cover 6 engage with the second limiting part 41, achieving comprehensive, bidirectional axial fixation of the second conductive element 4. This dual limiting effectively prevents axial displacement of the second conductive element 4 when subjected to insertion force, extraction force, or impact, greatly improving the stability of the second conductive element 4 installed inside the second housing 21 and the reliability of the connector.

[0031] like Figure 2 As shown, the locking structure of this embodiment includes a locking guide groove 51 disposed on the inner wall of the first housing 11 and a latch 52 disposed on the outer wall of the second housing 21; the latch 52 engages with the locking guide groove 51. The engagement of the latch 52 with the locking guide groove 51 provides a precise and reliable mechanical lock for the first housing 11 and the second housing 21. The engagement of the locking guide groove 51 and the latch 52 effectively locks the male end 1 and the female end 2 together, solving the problem of unstable mechanical connection of the connector in harsh environments, and supporting rapid rotation locking operation, ensuring convenient connection.

[0032] like Figure 2 As shown, the locking guide groove 51 in this embodiment includes a guide groove 511 and a locking groove 512; The buckle 52 is slidably connected to the guide groove 511, providing clear guidance for the male end 1 and the female end 2 during the rotation locking process, making the operation smoother and more convenient.

[0033] The locking groove 512 engages with the latch 52. When the latch 52 reaches the locked position, it engages with the locking groove 512, reliably maintaining the connector's locked state and effectively preventing accidental loosening, thereby further ensuring the reliability of the mechanical locking.

[0034] like Figure 2 As shown, the elastic structure in this embodiment is a first elastic element 7, which includes a first fixing ring 71, a second fixing ring 72, and an arc-shaped elastic bar 73. Both the first fixing ring 71 and the second fixing ring 72 abut against the second conductive element 4. There are multiple arc-shaped elastic bars 73, and multiple arc-shaped elastic bars 73 are connected between the second fixing ring 72 and the second conductive element 4.

[0035] The multiple arc-shaped elastic strips 73 provide uniform, multi-point, and sustained contact pressure to the inserted first conductive element 3, significantly improving the reliability of the conductive contact between the first conductive element 3 and the second conductive element 4. Simultaneously, both the first fixing ring 71 and the second fixing ring 72 abut against the second conductive element 4, ensuring the installation stability of the first elastic element 7 itself and further guaranteeing the long-lasting reliability of the conductive connection.

[0036] like Figure 3 As shown, the elastic structure in this embodiment is a second elastic element 8, which includes spring pieces 81 spaced apart from the second conductive element 4. The spring pieces 81 achieve elastic contact between the first conductive element 3 and the second conductive element 4. The spring piece 81 structure provides uniform and stable radial contact pressure when the first conductive element 3 is inserted, ensuring the reliability and stability of the conductive contact and effectively solving the technical problem of unstable conductive contact. Simultaneously, the design of the spring piece 81 and the second conductive element 4 has good integration, which helps simplify the internal design of the connector.

[0037] like Figure 3 As shown, the second outer shell 21 of this embodiment has a constriction portion 211 inside, which abuts against the spring piece 81. The constriction portion 211 achieves axial fixation and limitation of the spring piece 81. The constriction portion 211 effectively prevents the spring piece 81 from axially displacing when the first conductive member 3 is inserted, removed, or subjected to force, ensuring the installation stability of the second elastic member 8 inside the second outer shell 21, and further ensuring the long-term reliability of the conductive connection.

For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
