Description

Technical Field

[0001] This application relates to the field of connector technology, and in particular to a connector. Background Technology

[0002] Electrical connectors are indispensable basic components in modern electronic, electrical, and communication systems, and their reliability directly affects the stability and safety of the entire system. To ensure that connectors do not loosen under conditions such as vibration, impact, or accidental pulling, they are usually designed with specialized locking mechanisms. Currently, the most common locking methods on the market include threaded tightening, snap-fit, and push-pull self-locking. Among them, threaded tightening connections, although providing high locking force and extreme security, are cumbersome to operate, inefficient, and it is difficult to determine whether the optimal locking state has been achieved. In contrast, snap-fit ​​connections, while allowing for quick insertion and removal, have lower locking force, and the elastic elements they rely on are at risk of aging or breakage, resulting in limited reliability.

[0003] Although more advanced push-pull self-locking connectors offer a balance between speed and reliability to some extent, their internal structure is usually more complex, resulting in higher manufacturing costs.

[0004] In summary, existing technical solutions often fail to simultaneously meet the key requirements of quick and convenient operation, high reliability of connection, clear feedback on locking status, and reasonable manufacturing cost.

[0005] There is a need for a new type of connector that can achieve the robustness of a threaded connection, enable quick and convenient operation, and provide the operator with a clear locking confirmation signal to avoid connection risks caused by misoperation. Utility Model Content

[0006] The purpose of this application is to provide a novel connector that solves the problems of complex operation or low reliability of connectors in the prior art.

[0007] To achieve the above objective, this application provides a connector, including a male head and a female head that can be plugged into each other.

[0008] The outer peripheral wall of the male head is provided with a locking groove for locking with the female head;

[0009] The female head is equipped with a rotating sleeve, which can rotate relative to the female head;

[0010] The inner wall of the rotating sleeve is provided with a boss that mates with the slot;

[0011] The male and female connectors are locked together by the cooperation of the slot and the boss.

[0012] Preferably, the boss is connected to the slot by rotation.

[0013] Preferably, the male head has a locking boss in the slot. When the boss on the rotating sleeve is at the end of the slot, the rotating sleeve is locked and limited by the locking boss.

[0014] Preferably, there are three slots, which are evenly distributed circumferentially on the outer peripheral wall of the male connector.

[0015] Preferably, the female head is provided with a first rotating stop platform, and the rotating sleeve is provided with a second rotating stop platform that cooperates with the first rotating stop platform. The cooperation between the first rotating stop platform and the second rotating stop platform is used to limit the rotation angle of the rotating sleeve.

[0016] Preferably, the outer peripheral wall of the female head is provided with a first retaining ring groove, and the inner wall of the rotating sleeve is provided with a second retaining ring groove, and an open retaining ring is installed in the second retaining ring groove;

[0017] During the process of pressing the female head into the rotating sleeve, when the first circlip groove and the second circlip groove are aligned, the open circlip limits the relative positioning of the female head and the rotating sleeve.

[0018] Preferably, the male connector has a first anti-foolproof feature on its mating surface, and the female connector has a second anti-foolproof feature on its mating surface that matches the first anti-foolproof feature.

[0019] Preferably, the male head is provided with a first pin and a second pin, and the female head is provided with a socket that mates with the first pin and the second pin. The tail of the first pin and the tail of the socket are provided with double barbs, which are used to fix the first pin and the second pin in the male head or the female head.

[0020] Preferably, the outer side of the rotating sleeve is provided with anti-slip texture.

[0021] Preferably, the slot is L-shaped and includes an axial guide section parallel to the insertion / removal direction of the male connector and a circumferential locking section communicating with the end of the axial guide section.

[0022] Compared to the aforementioned background technology, this solution overcomes the shortcomings of existing technologies by setting a groove on the male end, fitting a rotatable rotating sleeve on the female end, and utilizing the engagement of a boss on the inner wall of the rotating sleeve with the groove for locking. Compared to traditional threaded connections, this solution eliminates the need for cumbersome multi-turn rotations, requiring only a single small-angle turn to achieve rapid locking and unlocking, significantly improving operational efficiency. Compared to ordinary snap-fit ​​connections, its mechanical interlocking structure is more robust, provides stronger locking force, and offers higher connection reliability.

[0036] 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, and 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.

[0037] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] It should be noted that the directional terms such as "upper end," "lower end," "left side," and "right side" mentioned below are defined based on the accompanying drawings in the instruction manual.

[0039] Please see Figures 1 to 10 A connector includes a male head 1 and a female head 13 that can be plugged into each other, a slot 2 formed on the male head 1, and a rotating sleeve 7 disposed on the female head 13.

[0040] The rotating sleeve 7 has a boss 8 on its inner wall. When connecting the male connector 1 and the female connector 13, the boss 8 on the inner wall of the rotating sleeve 7 is first aligned with the slot 2 on the outer peripheral wall of the male connector 1 and inserted. Then, the rotating sleeve 7 is rotated in a specific direction, causing the boss 8 to move inside the slot 2, ultimately achieving a reliable lock between the male connector 1 and the female connector 13. Furthermore, this solution eliminates the need for cumbersome multi-turn rotations; a single small-angle rotation is sufficient to quickly lock and unlock the connector, greatly improving operational efficiency.

[0041] The slot 2 is formed on the outer peripheral wall of the male head 1 and is used to lock with the female head 13; there are three slots 2, which are evenly distributed circumferentially on the outer peripheral wall of the male head 1.

[0042] Three sets of L-shaped slots 2, evenly distributed in a 120° circumferential direction, are opened on the outer peripheral wall of the metal shell of the male head 1. Their function is to form a geometric constraint with the linkage boss 8 on the inner wall of the rotating sleeve 7, so as to realize the reliable locking and stability control of the male head 1 and the female head 13.

[0043] The slot 2 is L-shaped and includes an axial guide section parallel to the insertion and removal direction of the male head 1 and a circumferential locking section connected to the end of the axial guide section.

[0044] The slot 2 adopts an L-shaped structure, comprising two functional areas: an axial guide section and a circumferential locking section. During connection operation: the boss 8 first undergoes linear displacement along the axial guide section (at this time, the male head 1 and the female head 13 remain relatively stationary in the circumferential direction); when the boss 8 touches the positioning surface at the end of the axial guide section, the rotational torque drives the rotating sleeve 7 to move the boss 8 in an arc along the circumferential locking section, simultaneously achieving stable contact between the pin 4 and the socket 5 under radial pressure. This design, through a two-stage action sequence from axial guidance to circumferential locking, achieves connection reliability exceeding that of spring clips while maintaining low insertion and extraction forces, making it suitable for long-term stable connections in vibration environments.

[0045] The female head 13 is provided with a rotating sleeve 7, which can rotate relative to the female head 13; the outer side of the rotating sleeve 7 is provided with anti-slip texture. (See attached diagram) Figure 3 The rotating sleeve 7 is circular and has a protrusion 8 inside. The anti-slip texture makes it easy for the operator to rotate the rotating sleeve 7.

[0046] In some embodiments, the outer peripheral wall of the female head 13 is provided with a first snap ring groove 16, and the inner wall of the rotating sleeve 7 is provided with a second snap ring groove 9. An open snap ring 10 is installed in the second snap ring groove 9. During the process of the female head 13 being pressed into the rotating sleeve 7, when the first snap ring groove 16 and the second snap ring groove 9 are aligned, the open snap ring 10 limits the relative positioning of the female head 13 and the rotating sleeve 7.

[0047] The female head 13 and the rotating sleeve 7 adopt an innovative elastic snap-fit ​​axial limiting mechanism. Specifically, a first snap ring groove 16 is precisely machined on the outer peripheral wall of the female head 13, and a second snap ring groove 9 is provided at the corresponding position on the inner wall of the rotating sleeve 7. Moreover, an open snap ring 10 is pre-installed in the second snap ring groove 9, and its design diameter is greater than the groove depth to ensure elastic pre-tightening force.

[0048] During the assembly and locking process of the rotating sleeve 7 onto the female head 13: when the rotating sleeve 7 is pressed into the female head 13 along the axis, the inner wall will gradually compress the open retaining spring 10. When the second retaining spring groove 9 and the first retaining spring groove 16 are precisely aligned, the elastic restoring force of the retaining spring 10 will cause it to automatically engage in the annular space formed by the double grooves. This process produces obvious tactile feedback and an audible "click" sound, providing operation confirmation for the assembly personnel.

[0049] This method prevents the axial loosening of the rotating sleeve 7 by mechanical hard limiting, and the annular design of the second snap ring groove 9 and the first snap ring groove 16 can also ensure that the rotating sleeve 7 can rotate without resistance in the circumferential direction.

[0050] The inner wall of the rotating sleeve 7 is provided with a boss 8 that mates with the slot 2. The male head 1 and the female head 13 are locked together through the engagement of the slot 2 and the boss 8. Specifically, the boss 8 is connected to the slot 2 by rotation.

[0051] The mechanism, through the cooperation of the boss 8 and the L-shaped slot 2, first achieves precise guidance and insertion by means of the axial groove section, ensuring the accuracy of the initial alignment; then, a two-stage locking mechanism is formed by circumferential rotation: initially ensuring positioning and finally achieving mechanical self-locking.

[0052] In some embodiments, the male head 1 has a locking boss 3 in the slot 2. When the boss 8 on the rotating sleeve 7 is at the end of the slot 2, the locking boss 3 locks and limits the rotating sleeve 7.

[0053] This invention provides a mechanical locking mechanism with multiple protective functions by setting a locking boss 3 in the slot 2, which cooperates with the boss 8 on the rotating sleeve 7. The mechanism automatically triggers locking when the boss 8 rotates to the end of the slot 2. The locking boss 3 forms a circumferential barrier, effectively preventing accidental loosening of the connecting parts due to vibration or external force. The design employs a gradually rising inclined surface structure, making the locking process smooth while requiring appropriate torque for unlocking, ensuring both locking reliability and ease of operation. When the boss 8 is in position, a clear tactile feedback (change in resistance) and an audible "click" sound indicate that locking is complete. The locking boss 3 is optimized to ensure that locking only occurs when the boss 8 is fully in position, avoiding the risk of partial locking.

[0054] In some embodiments, the female head 13 is provided with a first rotating stop platform, and the rotating sleeve 7 is provided with a second rotating stop platform 11 that cooperates with the first rotating stop platform. The cooperation between the first rotating stop platform and the second rotating stop platform 11 is used to limit the rotation angle of the rotating sleeve 7.

[0055] The first rotating stop platform on the female head 13 and the second rotating stop platform 11 on the rotating sleeve 7 form an angle limiting mechanism. This embodiment can precisely limit the maximum rotation angle of the rotating sleeve 7 and achieve buffering through gradual rotational resistance when approaching the limit, avoiding hard impact. Furthermore, the anti-misalignment design ensures the uniqueness of the assembly direction through the asymmetrical boss shape, and tactile feedback points are set at the extreme positions, allowing the operator to accurately perceive the rotation position by hand.

[0056] In some embodiments, the mating surface of the male connector 1 is provided with a first anti-foolproof feature 5, and the mating surface of the female connector 13 is provided with a second anti-foolproof feature 12 that matches the first anti-foolproof feature 5.

[0057] In some embodiments, the male head 1 is provided with a first pin 4 and a second pin 6, and the female head 13 is provided with a socket 15 that mates with the first pin 4 and the second pin 6. The tail of the first pin 4 and the tail of the socket 15 are provided with double-ring barbs 14, which are used to fix the first pin 4 and the second pin 6 in the male head 1 or the female head 13.

[0058] The first pin 4 and the second pin 6 are arranged in an asymmetrical manner (the center distance between the first pin 4 and the second pin 6 is different). Together with the first anti-misoperation feature 5 and the second anti-misoperation feature 12, they ensure that the male head 1 and the female head 13 are inserted in the correct direction, avoiding damage to the snap-fit ​​structure due to misoperation.

[0059] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.
