Description

Technical Field

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

[0002] After the connector fixed end and the connector plug-in end are plugged in, they achieve electrical connection for communication. To ensure stable communication, a locking mechanism is needed to lock the connector fixed end and the connector movable end to prevent the connector plug-in end from being pulled out by tension, which would cause communication interruption. The existing technology extends a cantilever latch 4 from the side of the connector plug-in end, and forms a slot for inserting the cantilever latch on the connector fixed end. A fixing hook is set on the side wall of the slot. When the connector plug-in end is plugged into the connector fixed end, the cantilever latch on the connector plug-in end is simultaneously inserted into the slot of the connector fixed end. The elasticity of the cantilever allows the hook on the cantilever latch to engage with the fixing hook inside the slot of the connector fixed end. When pulled out, pressing the end of the cantilever causes the hook to separate.

[0003] In the prior art, this locking structure requires space in the cavity of the fixed end, resulting in a large volume of the fixed end of the connector. Furthermore, this locking structure is difficult to apply to splicing plug-in ends. Summary of the Invention

[0004] To overcome the above shortcomings, this utility model provides a locking structure for a pluggable connector. This locking structure reduces the volume and material usage of the connector's fixed end and can also be applied to the pluggable end of splicing connectors.

The outer wall of the connector fixed end is provided with a fixed hook. A latch is installed on the outer wall of the connector pluggable end, which can rotate at a set angle. The latch forms a lever structure with its pivot as the fulcrum. The pivot of the latch extends along the direction perpendicular to the pluggable direction. The latch has a movable hook and a pressing operation arm at its two ends of the fulcrum, respectively. The movable hook can engage or disengage with the fixed hook as the latch rotates forward and backward. Pressing the pressing operation arm on the latch can make the movable hook rotate in the direction of disengagement from the fixed hook. A latch elastic element is also provided, which can provide an elastic force to the movable hook to rotate in the direction of engagement with the fixed hook.

[0006] As a further improvement of this utility model, the locking elastic element is an elastic cantilever structure integrally formed on the side wall of the locking element. The free end of the elastic cantilever structure can elastically abut against the side wall of the connector insertion end, and the deformation elastic force of the elastic cantilever structure provides rotational torque to the locking element.

[0007] As a further improvement of this utility model, the latch is a V-shaped structure, and the pivot of the latch is a protruding post located on both sides of the bend of the V-shaped structure. A latch mounting groove is formed on the side wall of the connector plug-in end, and shaft holes are respectively provided on both sides of the latch mounting groove. The protruding posts on both sides of the bend of the latch V-shaped structure are rotatably inserted into the shaft holes on both sides of the latch mounting groove.

[0008] As a further improvement of this utility model, the elastic cantilever structure extends from the pressing operation arm toward the movable hook, and the opening of the latch mounting groove is provided with a stop beam that spans the latch. The free end of the elastic cantilever structure of the latch is pressed against the stop beam, thereby giving the pressing operation arm of the latch an elastic pressure toward the direction of keeping the movable hook and the fixed latch engaged.

[0009] As a further improvement of this utility model, the elastic cantilever structure extends from the bend of the V-shaped structure of the latch toward the direction of the pressing operation arm, and the free end of the elastic cantilever structure of the latch is tightly pressed against the bottom surface of the latch mounting groove, thereby giving the pressing operation arm of the latch elastic pressure toward the direction of keeping the movable hook and the fixed latch engaged.

[0010] As a further improvement of this utility model, the locking elastic element is a spring, with both ends of the spring connected to the side wall of the connector plug-in end and the locking buckle respectively. The spring provides the pressing operating arm of the locking buckle with an elastic force in the direction of keeping the movable hook and the fixed locking buckle engaged.

[0011] As a further improvement of this utility model, a locking mounting groove is formed on the side wall of the connector plug-in end. A shaft hole is provided on each side wall of the locking mounting groove. The rotating shaft on the lock is a protrusion on each side wall in the width direction of the lock. The protrusion is inserted into the shaft hole. The pressing operation arm of the lock can be accommodated in the locking mounting groove on the side wall of the connector plug-in end. A spring mounting groove is provided on the bottom surface of the locking mounting groove on the side wall of the connector plug-in end. A spring guide post is provided on the pressing operation arm of the lock. One end of the spring is fixedly inserted into the spring mounting groove, and the other end of the spring is fixedly sleeved on the outside of the spring guide post. When the pressing operation arm is pressed, it can compress the spring and insert the spring guide post into the spring mounting groove.

[0012] As a further improvement of this utility model, the connector plug-in end includes a left plug-in body and a right plug-in body. The left plug-in body and the right plug-in body are connected by riveting through riveting holes and riveting posts to form an integral unit. The two side walls of the locking mounting groove are respectively located on the left plug-in body and the right plug-in body.

[0013] As a further improvement of this utility model, the end surface of the pressing operation arm of the latch is provided with a pressing operation surface, and the pressing operation surface is formed with a textured structure.

[0014] As a further improvement of this utility model, the fixing hook on the side wall of the fixed end of the connector is an inverted protrusion structure, and the side wall of the movable hook end of the lock is formed with an inverted hook body. When the connector plug-in end is plugged into the connector fixed end, the inverted hook body of the movable hook of the lock and the inverted protrusion of the fixed hook are in contact through the inclined surface.

[0015] The beneficial technical effects of this utility model are as follows: A fixing hook is fixedly installed on the outer wall of the connector fixed end, and a latch is hinged to the outer wall of the connector plug-in end. When the connector plug-in end is inserted into the connector fixed end, the movable hook of the latch automatically hooks onto the fixing hook on the outer wall of the connector fixed end under the action of the latch elastic element, thus locking the connector plug-in end and the connector fixed end. When pulling out the connector plug-in end, simply pinch the pressing arm of the latch and the side wall of the connector plug-in end with your fingers and pull the connector plug-in end outwards. This utility model eliminates the need for an additional slot for the latch to be inserted into the connector fixed end; only a fixing hook on the side wall of the connector fixed end is required, reducing the volume and material usage of the connector fixed end. Furthermore, the latch structure of this utility model can be applied to both integrated plug-in ends and spliced ​​plug-in ends, making it widely applicable. Attached Figure Description

Detailed Implementation

[0017] Example: A locking structure for a pluggable connector includes a connector fixed end 1 and a connector pluggable end 2. The connector fixed end 1 has a socket 11, and one end of the connector pluggable end 2 has a plug pin 21. The plug pin 21 can be inserted into the socket 11 of the connector fixed end 1 to achieve electrical connection between the pluggable end and the connector fixed end. A fixing hook 12 is provided on the outer wall of the connector fixed end 1, and a locking buckle 3 is installed on the outer wall of the pluggable end, which can rotate at a set angle. The locking buckle 3 is formed by… The lever structure has a pivot as its fulcrum. The pivot of the latch 3 extends along the vertical insertion and extraction direction. The latch 3 has a movable hook 31 and a pressing operating arm 32 at its two ends of its fulcrum, respectively. The movable hook 31 can engage or disengage with the fixed hook 12 as the latch 3 rotates in both directions. Pressing the pressing operating arm 32 on the latch 3 can cause the movable hook 31 to rotate in the direction of disengaging from the fixed hook 12. The latch 3 also has an elastic element, which can provide an elastic force to the movable hook 31 to rotate in the direction of engaging with the fixed hook 12.

[0018] When using the pluggable connector, the plug pin 21 of the pluggable end 2 is inserted into the socket 11 of the connector fixed end 1, achieving terminal contact and conduction. Simultaneously, the movable hook 31 of the latch 3 mounted on the side wall of the pluggable end 2 engages with the fixed hook 12 on the outer side wall of the connector fixed end 1. Under the elastic force of the latch 3's elastic element, the latch 3 remains engaged with the fixed hook 12. At this time, even under tension, the pluggable end 2 cannot detach from the connector fixed end 1, maintaining stable communication. To remove the pluggable end 2 from the connector fixed end 1, simply... By grasping the side wall of the connector plug-in end 2 and the pressing operating arm 32 of the latch 3, the pressing operating arm 32 of the latch 3, after being subjected to pressure in the vertical plugging and unplugging direction, overcomes the elastic force of the latch 3 elastic element and swings, causing its movable hook 31 to disengage from the fixed hook 12. At this time, the plug-in end of the connector can be pulled out directly. This utility model has a simple structure and does not require a slot for the latch 3 to be inserted on the connector fixed end 1. It can simplify the structure of the connector fixed end 1, reduce the volume of the connector fixed end 1, and save the materials required for the production of the connector fixed end 1. This latch 3 structure can be used on various types of connectors and is more flexible in use.

[0019] The locking element 3 is an integrally formed elastic cantilever structure 33 on the side wall of the locking element 3. The free end of the elastic cantilever structure 33 can elastically abut against the side wall of the connector insertion end 2. The deformation elastic force of the elastic cantilever structure 33 provides rotational torque to the locking element 3. By using the elastic cantilever structure 33 integrally formed on the side wall of the locking element 3, no additional elastic element is needed, saving parts and facilitating assembly. The free end of the elastic cantilever mechanism abuts against the side wall of the connector insertion end 2, and the elastic deformation of the elastic cantilever structure 33 achieves unlocking and locking.

[0020] The latch 3 has a V-shaped structure, and its pivot is a protruding post 34 located on both sides of the bend of the V-shaped structure. A latch mounting groove 22 is formed on the side wall of the connector plug-in end 2. Shaft holes 221 are respectively provided on both sides of the latch mounting groove 22. The protruding posts 34 on both sides of the bend of the V-shaped structure of the latch 3 are rotatably inserted into the shaft holes 221 on both sides of the latch mounting groove 22. The latch 3's V-shaped structure allows its pressing arm 32 to extend from the latch mounting groove 22, facilitating pressing operation and enabling the integral molding of the elastic cantilever structure 33. The bottom surface of the latch mounting groove 22 can be a V-shaped groove with an angle greater than the included angle of the latch 3's V-shaped structure, allowing the latch 3's swing angle to be limited by the bottom surface of the latch mounting groove 22.

[0021] The elastic cantilever structure 33 extends from the pressing operating arm 32 toward the movable hook 31. A stop beam 222 spanning the latch 3 is provided at the opening of the latch mounting groove 22. The free end of the elastic cantilever structure 33 of the latch 3 abuts against the stop beam 222, thereby applying elastic pressure to the pressing operating arm 32 of the latch 3 in the direction of maintaining the movable hook 31 and the fixed latch 3 in engagement. By providing the stop beam 222 at the opening of the latch mounting groove 22, and by having the free end of the integrally formed elastic cantilever structure 33 on the latch 3 abut against the stop beam 222, an elastic torque is applied to the latch 3.

[0022] The elastic cantilever structure 33 extends from the V-shaped bend of the latch 3 toward the pressing operating arm 32. The free end of the elastic cantilever structure 33 of the latch 3 abuts against the bottom surface of the latch mounting groove 22, thereby applying elastic pressure to the pressing operating arm 32 of the latch 3 in the direction of maintaining the engagement between the movable hook 31 and the fixed latch 3. The elastic cantilever structure 33 of the latch 3 and the pressing operating arm 32 of the latch 3 form a U-shaped structure, and the elastic torque is achieved by the free end of the elastic cantilever structure 33 abutting against the bottom surface of the latch mounting groove 22.

[0023] The elastic element of the latch 3 is a spring 5. Both ends of the spring 5 are connected to the side wall of the connector plug-in end 2 and the latch 3, respectively. The spring 5 provides an elastic force to the pressing operating arm 32 of the latch 3 in the direction of engaging the movable hook 31 with the fixed latch 3. By utilizing the elastic force provided by the spring 5, the latch 3 can form a linear structure. When the spring 5 is a compression spring, it can be installed on the pressing operating arm 32 of the latch 3; when the spring 5 is a tension spring, it can be installed on the movable hook 31 of the latch 3; the spring 5 can also be a torsion spring, directly installed on the rotating shaft of the latch 3.

[0024] The connector plug-in end 2 has a locking mounting groove 22 on its side wall. The locking mounting groove 22 has shaft holes 221 on its two side walls. The pivot of the lock 3 is a protrusion 34 on each side wall in the width direction of the lock 3, which is inserted into the shaft hole 221. The pressing arm 32 of the lock 3 can be accommodated in the locking mounting groove 22 on the side wall of the connector plug-in end. The bottom surface of the locking mounting groove 22 on the side wall of the connector plug-in end 2 has a spring mounting groove 223. A spring guide post 35 is mounted on the pressing arm 32 of the lock 3. One end of the spring 5 is fixedly inserted into the spring mounting groove, and the other end of the spring 5 is fixedly sleeved on the outside of the spring guide post 35. When the pressing arm 32 is pressed, it can compress the spring 5 and insert the spring guide post 35 into the spring mounting groove 223. The spring mounting groove 223 and the elastic guide post can position and guide the spring 5, preventing radial deformation under pressure.

[0025] The connector plug-in end 2 includes a left plug-in body 23 and a right plug-in body 24. The left plug-in body 23 and the right plug-in body 24 are connected by riveting through riveting holes 25 and riveting posts 26 to form an integral unit. The two side walls of the locking mounting groove 22 are respectively located on the left plug-in body 23 and the right plug-in body 24. The connector plug-in end 2 is formed by splicing the left plug-in body 23 and the right plug-in body 24, which facilitates the assembly of the locking 3. Riveting holes 25 and riveting posts 26 can also be provided on both sides of the right plug-in body 24, and a plug-in body cover plate with only riveting posts 26 on the side wall can be designed to realize the splicing of multiple plug-in bodies to form a spliced ​​plug-in connector.
