Technical Field

[0001] This utility model relates to a connector, and more particularly to a locking mechanism for a connector. Background Technology

[0002] The existing connector locking mechanism consists of a slot on the socket and a spring hook 3 on the plug. In use, the plug is inserted into the socket slot, and the spring hook on the plug automatically engages with the slot 4 on the socket, thus locking the plug and socket. To unplug the plug, the operating part 5 on the plug needs to be pressed, causing the spring hook to swing at a certain angle and disengage from the slot. Simultaneously, the plug needs to be pulled outwards with force to remove it from the socket. This type of connector locking mechanism has the following disadvantages:

[0003] 1. When unplugging the plug, you need to press down on the latch on the plug and hold the plug to pull it out. This requires leaving space around the product for your hand. The product has a large operating space, resulting in wasted space and limiting the product's usability.

[0004] 2. Because pressing down on the operating end of the latch is required when unplugging the plug, it is more difficult to pull out the plug. Utility Model Content

[0016] The beneficial effects of this utility model are as follows: By setting a hook in the socket slot and a swingable hanging platform on the plug, when the plug is inserted into the socket slot, the hanging platform automatically engages with the hook to achieve a stable connection. When the plug needs to be removed, simply pull the lever on the plug outwards. As the other end of the lever slides outwards, it forces the hanging platform to reverse at a certain angle, thereby disengaging it from the hook in the socket and unlocking the plug from the socket. Continuing to pull the lever outwards will remove the plug from the socket slot. This utility model also has a retaining ring at the end of the lever located on the outside of the plug. When removing the plug, simply pull the ring outwards; there is no need to grip the plug tightly. The operation requires little space and can be used in confined spaces. The entire process only requires pulling the ring outwards, making it convenient and labor-saving. Attached Figure Description

[0040] Example: A locking mechanism for a connector, wherein the connector plug 1 can be inserted into the slot 21 of the socket 2 to achieve electrical connection, and a hook 211 is fixedly provided in the slot 21 of the socket 2. The plug 1 is provided with a hanging platform 11 that can be rotated at a set angle, and the plug 1 is also provided with a pull rod 12 that can slide a set distance along the insertion and removal direction of the plug 1. One end of the pull rod 12 extends to the outside of the end of the plug 1 facing away from the socket 2, and the other end of the pull rod 12 slides with the pull rod 12 to swing the hanging platform 11. When the hanging platform 11 swings forward, it can hook and position itself with the hook 211 in the slot 21 of the socket 2. When the hanging platform 11 swings backward, it can disengage and separate from the hook 211 in the slot 21 of the socket 2.

[0041] During normal communication, plug 1 is inserted into slot 21 of socket 2. The mounting plate 11 on plug 1 is engaged with the hook 211 inside slot 21 of socket 2 to achieve locking and positioning. When plug 1 needs to be removed, simply pull the lever 12 outward. The lever 12 slides under the pulling force, and the other end of the lever 12 swings in conjunction with the mounting plate 11 to disengage from the hook 211. Continue to pull the lever 12 outward, and the lever 12, along with plug 1, completely exits from slot 21 of socket 2. With this structure, when removing plug 1, it is not necessary to press the switch while holding plug 1 and pulling it outward. Just pull the lever 12. Removing plug 1 is convenient and effortless. It does not require gripping plug 1, saving space around plug 1. Plug 1 can be easily removed even in confined spaces.

[0042] One end of the pull rod 12 is fixedly provided with a pull ring 121 for inserting a finger. When taking out the plug 1, you only need to hook your finger on the pull ring 121 to pull the plug 1 outward, which is more convenient to operate, easier to apply force, and saves more operating space.

[0043] The other end of the pull rod 12 has a linkage inclined surface 122 that is inclined along the swing direction of the hanging platform 11. A push arm 111 is fixed on the hanging platform 11. The push arm 111 can slide along the linkage inclined surface 122, thereby driving the hanging platform 11 to swing. The other end of the pull rod 12 contacts the push arm 111 on the hanging platform 11 through the linkage inclined surface 122. When the pull rod 12 is pulled outward, the push arm 111 is pushed up by the linkage inclined surface 122, thereby causing the hanging platform 11 to rotate in the opposite direction around the pivot, realizing the disengagement of the hanging platform 11 from the hook 211. When the pull rod 12 is pushed inward towards the plug 1, the push arm 111 descends along the linkage inclined surface 122, thereby causing the hanging platform 11 to rotate in the forward direction around the pivot, realizing the engagement connection between the hanging platform 11 and the hook 211.

[0044] The push arm 111 on the mounting platform 11 is a hook-shaped structure formed by bending, and the hook-shaped structure has an inclined structure that matches the linkage inclined surface 122.

[0045] A limiting block 123 is also provided on the side wall of the pull rod 12, and a pull rod reset elastic element 112 is also provided on the mounting platform 11 or the plug 1. The pull rod reset elastic element 112 can provide an elastic holding force to the limiting block 123 on the side wall of the pull rod 12 towards the socket 2. By applying an elastic reset force to the pull rod 12 through the pull rod reset elastic element 112, the pull rod 12 will automatically return to its initial state after being released, so that the mounting platform 11 at the upper end of the plug 1 can automatically engage with the buckle on the socket 2 when the plug 1 is plugged into the socket 2 next time.

[0046] The pull rod reset elastic element 112 includes an elastic cantilever root extending from the mounting base 11 and a hook formed by bending the elastic cantilever root. The hook hooks onto the side wall of the limiting block 123 facing away from the socket 2. The elastic deformation of the elastic cantilever and the hook is used to adapt to the outward pull of the pull rod 12 and the automatic inward elastic reset. In addition to the above structure, the pull rod reset elastic element 112 can also be a spring installed on the plug 1, which provides elastic force to the pull rod 12 in the direction of the socket 2 to realize the automatic elastic reset of the pull rod 12. Such equivalent replacement structures are easily conceived by those skilled in the art based on this patent and are within the scope of protection of this patent.

[0047] The mounting bracket 11 is also equipped with a torque reset elastic element 113, which can provide a positive swing torque to the mounting bracket 11. When the pull rod 12 is released, the mounting bracket 11 rotates forward and returns to its initial state under the action of the torque reset elastic element 113, so that when the plug 1 is plugged into the socket 2 next time, the upper end of the mounting bracket 11 of the plug 1 can automatically and stably engage with the buckle on the socket 2.

[0048] The plug 1 is provided with a mounting plate reset baffle 13. The torque elastic reset component is an elastic cantilever structure integrally formed on the mounting plate 11. The elastic cantilever structure can swing synchronously with the swing of the mounting plate 11, and the elastic cantilever structure extends inclined towards the opposite swing direction of the mounting plate 11. The free end of the elastic cantilever structure can elastically press against the mounting plate reset baffle 13 on the plug 1 as the mounting plate 11 swings in the opposite direction, and generate elastic deformation. The elastic deformation generated by the elastic cantilever structure integrally formed on the mounting plate 11 being blocked by the mounting plate reset baffle 13 gives the mounting plate 11 a tendency to rotate in the forward direction. In addition, the torque reset elastic component 113 can also be a torsion spring installed on the rotating shaft of the mounting plate 11, which provides the mounting plate 11 with a forward rotation torque. The torque reset elastic component 113 can also be a tension spring or a compression spring, which provides tension or pressure to the edge of the mounting plate 11, causing it to rotate in the forward direction. These are equivalent replacement structures that are easily conceived by those skilled in the art based on this patent and are within the scope of protection of this patent.

[0049] The plug 1 has a locking channel extending along its insertion / removal direction. The mounting bracket 11 is installed in the locking channel. The other end of the pull rod 12 can be slidably inserted into the locking channel. A limiting groove is provided on the inner side wall of the locking channel. A limiting protrusion 124 is fixedly provided on the side wall of the pull rod 12. The limiting protrusion 124 can be slidably inserted into the limiting groove. A hook positioning rod 212 extending along its depth direction is fixedly provided on the bottom surface of the slot 21 of the socket 2. The hook 211 with an inverted structure is fixedly provided on one side wall of the end of the hook positioning rod 212. When the plug 1 is inserted into the slot 21 of the socket 2, the hook positioning rod 212 and the hook 211 on it are correspondingly inserted into the locking channel of the plug 1, and the other side wall of the hook positioning rod 212 is stopped on the inner side wall of the locking channel. The locking channel is used to accommodate the mounting platform 11 and its push arm 111, pull rod reset elastic element 112 and torque elastic reset element. The locking channel also limits the swing angle of the mounting platform 11 and guides the sliding of the pull rod 12. The limiting protrusion 124 on the pull rod 12 slides in the limiting groove on the side wall of the locking channel, which can limit the sliding distance of the pull rod 12. The locking channel also allows the hook positioning rod 212 to be inserted and supports the hook positioning rod 212 to ensure a stable connection between the hook 211 and the mounting platform 11.

[0050] The mounting bracket 11 has a rectangular frame structure. An inclined guide arm 114 is fixedly provided at one end of the mounting bracket 11 facing the socket 2. The inclined guide arm 114 contacts the hook 211 via its inclined surface. By providing the inclined guide arm 114 in front of the mounting bracket 11 before insertion, and utilizing its inclined surface to contact the hook 211, rotational guidance is achieved before the mounting bracket 11 and hook 211 are engaged, preventing the mounting bracket 11 from jamming and failing to engage when the plug 1 is inserted.
