Description

Technical Field

[0001] This utility model relates to a connector, and more particularly to a locking structure in which the locking and unlocking direction is parallel to the insertion and removal direction. Background Technology

[0002] Existing connector locking mechanisms require the handle 4 to be turned along the vertical plug insertion / removal direction (generally the connector width direction) to unlock, and the locking mechanism is released through the handle linkage. This structure occupies a lot of space in the product width direction during the opening and closing movement of the handle 4 during the unlocking process, and cannot meet the user's need for a mechanical locking structure in a compact space. Utility Model Content

[0003] To overcome the above deficiencies, this utility model provides a locking structure in which the locking and unlocking direction is parallel to the insertion and removal direction. This locking structure in which the locking and unlocking direction is parallel to the insertion and removal direction can meet the user's needs for a locking structure in a compact space.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a locking structure with the locking and unlocking direction parallel to the insertion and removal direction, including a socket and a plug. The socket is provided with a socket hole, and one end of the plug is provided with a plug pin. The plug pin can be inserted into the socket hole to realize the electrical connection between the plug and the socket. The socket is provided with a first latch, and the plug is provided with a second latch. The second latch can reciprocate a set distance on the plug along the direction perpendicular to the plug insertion and removal direction. When the plug pin of the plug is fully inserted into the socket hole, the reciprocating movement of the second latch along the direction perpendicular to the plug insertion and removal direction can engage or disengage with the first latch. The plug is also provided with an unlocking handle that can slide back and forth a set distance along the direction of plug insertion and removal. One end of the unlocking handle has an operating part exposed on the outer wall of the plug. The other end of the unlocking handle is linked with the second latch. By pushing and pulling the operating part at one end of the unlocking handle, the other end of the unlocking handle can drive the second latch to reciprocate along the direction perpendicular to the plug insertion and removal direction, thereby realizing the engagement or disengagement of the second latch with the first latch.

[0005] As a further improvement of this utility model, the socket is provided with a locking slot extending in the same direction as the socket. The first latch is a slot (which can be a groove or an opening) provided on the side wall of the locking slot. The second latch can be inserted into the slot to achieve a latching connection with the first latch, or disengage from the slot to achieve a disengagement from the first latch.

[0006] As a further improvement of this utility model, at least one locking slot is connected to at least one socket on the socket to form an integral structure, and at least one second buckle is installed on the side wall of at least one plug post. The second buckle is provided with a driving surface, and a locking gap is formed between the driving surface and the side wall of the plug post for the other end of the unlocking handle to be inserted. When the unlocking handle reciprocates along the plug insertion and removal direction, its other end can be inserted into or removed from the locking gap. The unlocking handle and the driving surface are in contact through an inclined surface extending along the sliding direction of the unlocking handle. The reciprocating sliding of the unlocking handle along the plug insertion and removal direction can force the second buckle to reciprocate along the direction perpendicular to the plug insertion and removal direction.

[0007] As a further improvement of this utility model, the second buckle includes an elastic cantilever provided on the side wall of the plug-in post and a protrusion provided on the side wall of the free end of the elastic cantilever. A locking gap is formed between the elastic cantilever and the side wall of the plug-in post. The elastic cantilever and the protrusion at its free end can be inserted into the locking slot of the socket together with the plug-in post. When the elastic cantilever is in a free state, the protrusion is located in the slot on the side wall of the locking slot or in the slot on the side wall of the locking slot. The other end of the unlocking handle slides back and forth along the locking gap, which can force the elastic cantilever to swing elastically, thereby allowing the protrusion at its free end to be inserted into the slot on the side wall of the locking slot to lock or to be released from the slot on the side wall of the locking slot to unlock.

[0008] As a further improvement of this utility model, the elastic cantilever of the second buckle extends obliquely along the plug insertion direction, the root of the elastic cantilever is located in the direction of the plug end, the free end of the elastic cantilever is located in the direction of the plug root, a wedge-shaped locking gap is formed between the elastic cantilever and the plug, the other end of the unlocking handle forms an arc contact surface, the unlocking handle contacts the elastic cantilever through the arc contact surface, and the thickness of the other end of the unlocking handle in the elastic swing direction of the elastic cantilever is greater than the root size of the wedge-shaped locking gap.

[0009] As a further improvement of this utility model, the plug is provided with a handle guide slide extending along the plug insertion and removal direction, the unlocking handle is inserted into the handle guide slide, and the unlocking handle can only slide back and forth in a straight line along the extension direction of the handle guide slide.

[0010] As a further improvement of this utility model, the side wall of the handle guide slide is also provided with an elongated hole extending along the plug insertion and removal direction. Limiting recesses are formed at both ends of the side wall of the elongated hole along the sliding direction of the unlocking handle. A guide post is provided on each of the two side walls in the width direction of the unlocking handle. The guide post can be slidably inserted into the elongated hole, and the guide post can be stopped and held in the limiting recess by the elastic pressure of the elastic cantilever.

[0011] As a further improvement of this utility model, the handle guide slide on the plug includes at least a pair of first baffles on the outer wall of the plug and at least a pair of second baffles on the side wall of the plug pin. The first baffle has an L-shaped cross-section. One end of the unlocking handle is inserted between the pair of first baffles, and the four sides of the unlocking handle perpendicular to its sliding direction are stopped on the inner side wall of the pair of first baffles. The other end of the unlocking handle is inserted between the pair of second baffles to achieve sliding guidance. The elongated hole is provided on at least one of the first baffles and the second baffle.

[0012] As a further improvement of this utility model, the operating part of the unlocking handle is a boss provided on one end of the unlocking handle. The boss can be accommodated in the gap between the pair of first retaining walls, and the surface of the boss is formed with an undulating pattern.

[0013] As a further improvement of this utility model, a reinforcing rib is also provided on the side wall of the other end of the unlocking handle.

[0014] The beneficial technical effects of this utility model are as follows: This utility model provides an unlocking handle on the plug that moves along the plug insertion and removal direction, and forms an operating part at one end of the unlocking handle for pushing and pulling it. The second latch installed on the plug moves back and forth along the direction perpendicular to the plug insertion and removal direction through the linkage of the other end of the unlocking handle, thereby realizing the engagement or disengagement with the first latch on the socket. When the plug is pulled directly by external force, it cannot be pulled out of the socket. It is necessary to push and pull the unlocking handle to unlock the second latch and the first latch before the plug can be pulled out of the socket. This structure changes the locking and unlocking direction of the connector latch from perpendicular to the insertion and removal direction to parallel to the insertion and removal direction. The space occupied in the movement stroke direction is small, which can meet the user's needs for a latch structure in a compact space. Attached Figure Description

[0024] Example: A locking structure with the locking and unlocking direction parallel to the insertion and removal direction includes a socket 1 and a plug 2. The socket 1 has a socket hole 11, and one end of the plug 2 has a plug pin 21. The plug pin 21 can be inserted into the socket hole 11 of the socket 1 to achieve electrical connection between the plug 2 and the socket 1. The socket 1 has a first latch, and the plug 2 has a second latch. The second latch can reciprocate a set distance on the plug 2 along a direction perpendicular to the insertion and removal direction of the plug 2. When the plug pin 21 of the plug 2 is fully inserted into the socket hole 11 of the socket 1, the second latch... The reciprocating motion of the buckle along the vertical insertion and removal direction of the plug 2 can engage or disengage with the first buckle. The plug 2 is also provided with an unlocking handle 3 that can slide back and forth a set distance along the insertion and removal direction of the plug 2. One end of the unlocking handle 3 has an operating part 31 exposed on the outer wall of the plug 2. The other end of the unlocking handle 3 is linked with the second buckle. By pushing and pulling the operating part 31 at one end of the unlocking handle 3, the other end of the unlocking handle 3 can drive the second buckle to reciprocate along the vertical insertion and removal direction of the plug 2, thereby realizing the engagement or disengagement of the second buckle with the first buckle.

[0025] When the connector is plugged in and connected, the plug pin 21 of the plug 2 is inserted into the socket 11 of the plug 2. By pushing and pulling the operating part 31 of the unlocking handle 3, the unlocking handle 3 slides along the plug 2 insertion and removal direction. Then, the second latch on the plug 2 moves towards the first latch along the direction perpendicular to the plug 2 insertion and removal direction, and the second latch engages with the first latch. At this time, the plug 2 and the socket 1 are locked, and the plug 2 cannot be pulled out of the socket 1 by pulling it out directly. When it is necessary to remove the plug 2 from the socket 1, first push and pull the handle in the opposite direction by the operating part 31 of the unlocking handle 3. Then, the second latch on the plug 2 moves towards the direction perpendicular to the plug 2 insertion and removal direction. The plug 2 is pulled away from the first latch, and the second latch engages and disengages from the first latch. At this time, the plug 2 can be pulled outward to remove it from the socket 1. Finally, the unlocking handle 3 slides towards the socket 1 to engage the second latch with the first latch for locking. The unlocking handle 3 slides away from the socket 1 to disengage the second latch from the first latch for unlocking. This utility model has a simple structure. The unlocking handle 3 can be slid along the plug 2 insertion and removal direction to lock or unlock. In this way, the unlocking handle 3 does not occupy the space in the width direction of the connector when locking and unlocking, which can be used for insertion and removal operations in narrow spaces.

[0026] The socket 1 is provided with a locking slot extending in the same direction as the socket 11. The first latch is a slot 12 (which can be a groove or an opening) on ​​the side wall of the locking slot. The second latch reciprocates linearly along the insertion and removal direction of the plug 2, and can be inserted into the slot 12 to achieve a locking connection with the first latch, or disengage from the slot 12 to achieve a disengaging connection with the first latch. Locking and unlocking are achieved by sliding the second latch into or out of the slot 12 on the side wall of the locking slot along the insertion and removal direction of the plug 2. The structure is simple and the locking connection is stable.

[0027] At least one locking slot is connected to at least one socket 11 on the socket 1 to form an integral structure. At least one second buckle is installed on the side wall of at least one plug post 21. The second buckle is provided with a driving surface. A locking gap is formed between the driving surface and the side wall of the plug post 21 for the other end of the unlocking handle 3 to be inserted. When the unlocking handle 3 moves back and forth in the plug-in direction of the plug 2, its other end can be inserted into or out of the locking gap. The unlocking handle 3 and the driving surface are in contact through an inclined surface extending in the sliding direction of the unlocking handle 3. The reciprocating sliding of the unlocking handle 3 in the plug-in direction of the plug 2 can force the second buckle to move back and forth in a direction perpendicular to the plug-in direction of the plug 2.

[0028] The other end of the unlocking handle 3 contacts the second buckle through an inclined surface, so that the movement direction of the unlocking handle 3 is perpendicular to the movement direction of the second buckle. Alternatively, it can be achieved by the guide post 32 being inserted into the inclined hole, or by a linkage mechanism. This is an equivalent replacement structure that can be easily conceived by those skilled in the art based on this application, and it falls within the protection scope of this application.

[0029] The second latch includes an elastic cantilever 22 disposed on the side wall of the plug post 21 and a protrusion 23 disposed on the side wall of the free end of the elastic cantilever 22. A locking gap is formed between the elastic cantilever 22 and the side wall of the plug post 21. The elastic cantilever 22 and the protrusion 23 at its free end can be inserted into the latch slot of the socket 1 together with the plug post 21. When the elastic cantilever 22 is in a free state, the protrusion 23 is located in the slot 12 on the side wall of the latch slot or in the slot 12 on the side wall of the latch slot. The other end of the unlocking handle 3 slides back and forth along the locking gap, which can force the elastic cantilever 22 to swing elastically, thereby allowing the protrusion 23 at its free end to be inserted into the slot 12 on the side wall of the latch slot to lock or to be released from the slot 12 on the side wall of the latch slot to unlock. The elastic cantilever 22 has an elastic swing function. When the second latch is inserted into the integrated structure of the latch slot and the socket 11 along with the plug pin 21, the elastic cantilever 22 is in a free state, and the protrusion 23 is separated from the slot 12 of the socket 1. When the unlocking handle 3 is pushed in the insertion direction, the other end of the unlocking handle 3 abuts against the elastic cantilever 22 and generates an elastic swing. Finally, the protrusion 23 on the free end of the elastic cantilever 22 is inserted into the slot 12 on the side wall of the latch slot, at which point the plug 2 and the socket 1 are locked. Alternatively, when the elastic cantilever 22 is in a free state, the protrusion 23 on it is in a plugged-in and engaged position with the slot 12 of the socket 1. When the unlocking handle 3 is pushed in the insertion direction, the other end of the unlocking handle 3 abuts against the elastic cantilever 22 and generates an elastic swing. Finally, the elastic cantilever 22... The protrusion 23 on the end of the plug 2 disengages from the slot 12 on the side wall of the latch slot, thereby unlocking the plug 2 and the socket 1. Those skilled in the art can choose between these two driving methods as needed. When the elastic cantilever 22 is in a free state, and the protrusion 23 on it is in a plug-in and latched position with the slot 12, the side of the protrusion 23 that contacts the side wall of the latch slot needs to be designed as a slope or arc surface to guide and avoid it. In addition to adopting the above-mentioned elastic cantilever 22 structure with protrusion 23, the second latch can also be a T-shaped plug-in post 21 with a stepped surface designed as a slope for the other end of the unlocking handle 3 to be inserted and contacted. It can also be automatically and elastically inserted into the slot 12 or elastically disengaged from the slot 12 by setting a spring on it. This is an equivalent replacement structure that those skilled in the art can easily conceive of based on this application and is within the scope of protection of this application.

[0030] The elastic cantilever 22 of the second buckle extends obliquely along the insertion direction of the plug 2. The root of the elastic cantilever 22 is located at the end of the plug post 21, and the free end of the elastic cantilever 22 is located at the root of the plug post 21. A wedge-shaped locking gap is formed between the elastic cantilever 22 and the plug post 21. The other end of the unlocking handle 3 forms an arc-shaped contact surface. The unlocking handle 3 contacts the elastic cantilever 22 through the arc-shaped contact surface, and the thickness of the other end of the unlocking handle 3 in the elastic swing direction of the elastic cantilever 22 is greater than the root size of the wedge-shaped locking gap. The unlocking handle 3 slides in contact with the elastic cantilever 22 through the arc-shaped contact surface, ensuring smooth movement of the unlocking handle 3 and preventing it from getting stuck. The elastic cantilever 22 extends obliquely along the insertion and removal direction of the plug 2, so the other end of the unlocking handle 3 can be smoothly inserted and withdrawn from the unlocking gap, and gradually contact the elastic cantilever 22 and gradually lift it up. In addition, the elastic cantilever 22 can also extend parallel to the side wall of the plug post 21, and the other end of the unlocking handle 3 can be designed as a bevel.

[0031] The plug 2 is provided with a handle guide slide extending along the insertion and removal direction of the plug 2. The unlocking handle 3 is inserted into the handle guide slide, and the unlocking handle 3 can only slide back and forth in a straight line along the extension direction of the handle guide slide. The handle guide slide is used to install and guide the unlocking handle 3 on the side wall of the plug 2.

[0032] The handle guide slide sidewall is also provided with an elongated hole 24 extending along the insertion / removal direction of the plug 2. Limiting recesses 25 are formed at both ends of the sidewall of the elongated hole 24 along the sliding direction of the unlocking handle 3. A guide post 32 is provided on each of the two sidewalls of the unlocking handle 3 in the width direction. The guide post 32 is slidably inserted into the elongated hole 24, and is held in place within the limiting recess 25 by the elastic pressure of the elastic cantilever 22. The elongated hole 24 and the guide post 32 cooperate to further guide the sliding of the unlocking handle 3. Simultaneously, the two limiting recesses 25 on the sidewall of the elongated hole 24 enable automatic positioning of the unlocking handle 3 in the unlocked and locked positions, ensuring the unlocking handle 3 remains in both positions, guaranteeing a stable locked state, and preventing accidental locking due to vibration or other reasons.

[0033] The handle guide slide on the plug 2 includes at least a pair of first baffles 26 on the outer wall of the plug 2 and at least a pair of second baffles 27 on the side wall of the plug post 21. The first baffles 26 have an L-shaped cross-section. One end of the unlocking handle 3 is inserted between the pair of first baffles 26, and the four sides of the unlocking handle 3 perpendicular to its sliding direction are stopped on the inner side wall of the pair of first baffles 26. The other end of the unlocking handle 3 is inserted between the pair of second baffles 27 to achieve sliding guidance. The elongated hole 24 is provided on at least one of the first baffles 26 and the second baffles 27.

[0034] By setting the first barrier 26 and the second barrier 27 respectively to guide the two ends of the unlocking handle 3, it is ensured that the sliding direction of the unlocking handle 3 is consistent with the insertion and removal direction of the plug 2.

[0035] The operating part 31 of the unlocking handle 3 is a boss located on one end of the unlocking handle 3. The boss can be accommodated in the gap between the pair of first retaining walls 26, and the surface of the boss has an undulating pattern. The surface of the boss can be an arc surface that matches the fingertip.

[0036] The other end of the unlocking handle 3 is also provided with a reinforcing rib 33. This increases the strength of the other end of the unlocking handle 3 and prevents it from breaking or deforming under stress.
