Description

Technical Field

[0001] This invention relates to a plug-in connector, and more particularly to a plug-in connector with an improved structure. Background Technology

[0002] Currently, plug-in connectors rely on the friction between the plug and the socket to achieve a stable connection after the plug is inserted into the socket. However, if the connector is subjected to vibration or external force during use, the plug may easily become loose or even fall off the socket, resulting in poor circuit connection and open circuit. Summary of the Invention

[0003] To overcome the above-mentioned defects, the present invention provides a plug-in connector with improved structure, which can ensure that the plug and socket maintain a stable connection during the plugging process and avoid open circuit.

[0004] The technical solution adopted by the present invention to solve its technical problem is: an improved plug-in connector, including a plug and a socket, one end of the plug can be inserted into the socket to achieve electrical connection, a first buckle is provided on the side wall of the socket, and a second buckle is provided on the outer side wall of one end of the plug, the first buckle and the second buckle can be fastened together, and the plug or socket is also provided with a separation device, which can separate and release the first buckle from the second buckle.

[0005] Both the plug and socket include an insulating body and metal parts within the insulating body. When the plug and socket are inserted into each other, the corresponding metal parts also make point contact, thus forming an electrical connection. After the plug and socket are inserted, the first latch of the socket engages with the second latch of the plug, making the plug and socket inseparable. After operating the separation device, the separation device disengages the first latch from the second latch, allowing the plug to be pulled out of the socket. By setting the first and second latches on the plug and socket, a stable insertion state can be maintained when the plug and socket are inserted, preventing external forces from causing the metal parts on the plug and socket to detach, resulting in a circuit break and avoiding poor contact. When it is necessary to unplug the plug from the socket, simply operate the separation device to disengage the first latch from the second latch, allowing the plug to be easily unplugged. The engagement structure on the plug and socket can be one or more sets, and the corresponding separation device can be one or more, depending on the actual situation.

[0006] As a further improvement of the present invention, the first latch is a mounting platform located on the inner wall of the socket, and the second latch is a protruding locking point located on the outer wall of one end of the plug, or the first latch is a protruding locking point located on the inner wall of the socket, and the second latch is a mounting platform located on the outer wall of one end of the plug. The mounting platform can prevent the protruding locking point from moving in the direction of disengagement between the first and second latches. The mounting platform can be hung on the locking point 11 of the plug to prevent the plug and socket from separating, thereby realizing the fastening connection between the two. In addition to the fastening connection of the first and second latches by mounting platform and protruding locking point, magnetic elements can also be used to magnetically attract and fasten the two when they are close together, etc.

[0007] As a further improvement of the present invention, the mounting bracket is a concave groove, a perforated hole, or a hook structure, and the protruding locking point is an inverted snap structure, a hook structure, or a ball head structure with a thickness less in the direction towards the socket than in the direction away from the socket. The mounting bracket and the protruding locking point can be engaged and connected using any of the above structures; the specific structure is not limited, as long as the two can hook together.

[0008] As a further improvement of the present invention, the first buckle can be elastically moved along its fastening direction and installed on the side wall of the socket, or the second buckle can be elastically moved along its fastening direction and installed on the outer side wall of one end of the plug. The separation device can move the first buckle or the second buckle elastically to disengage the first buckle and the second buckle.

[0009] The plug and socket can be easily plugged in and quickly fastened by the elastic movement of the first or second latch to avoid collision. At the same time, after the first or second latch is disengaged, the elastically moving first or second latch can automatically reset to ensure automatic fastening after the next plugging. In addition to using the elastic movement to achieve a tight fastening of the first and second latches, a tight fit or a sliding and then stopped and positioned by the connector can also be used, such as using screws, pins, etc. These are equivalent design solutions that can be easily conceived by those skilled in the art based on this patent and are within the scope of protection of this patent.

[0010] As a further improvement of the present invention, the socket sidewall is formed by tearing to form at least one elastic cantilever structure, and the first buckle is fixedly installed on the cantilever structure of the socket sidewall; or at least one elastically deformable cantilever structure is formed on the outer sidewall of one end of the plug, and the second buckle is fixedly installed on the cantilever structure of the outer side of one end of the plug.

[0011] The first or second buckle can be made to move elastically by means of a cantilever structure. In addition, it can also be made by means of a spring and a sliding pin to form an elastic sliding pin, or by means of a spring piece, etc. These are equivalent design solutions that can be easily thought of by those skilled in the art based on this patent, and they are within the scope of protection of this patent.

[0012] As a further improvement of the present invention, the separating device includes an arched spring that can elastically deform. One end of the arched spring is fixedly connected to the outer wall of the socket or plug, and the other end of the arched spring forms a free end. The free end of the arched spring can extend into the cantilever structure on the outer wall of the plug or the cantilever structure on the socket sidewall, and the free end sidewall of the arched spring can press against the sidewall of the opening end of the cantilever structure to cause the cantilever structure to elastically deform in the direction of disengagement of the first and second latches.

[0013] By pressing the arched spring, the arched spring deforms and extends between the first and second latches, prying them apart and thus disengaging the first and second latches. Alternatively, the separation device can be a sliding button fixedly connected to the first or second latch. By pushing or pulling the sliding button, the first or second latch can be moved, thereby disengaging the first and second latches.

[0014] As a further improvement of the present invention, the free end of the cantilever structure on the side wall of the socket and the free end of the cantilever structure on the outer side wall of one end of the plug are formed with a chamfered structure or a warped structure to allow the free end of the arched spring to extend into. The free end of the arched spring forms a tapered upturned head with gradually decreasing thickness. The tapered upturned head of the free end of the arched spring is a flat structure that is flat against the outer side wall of the plug or the inner side wall of the socket. The tapered upturned head and the arcuate surface of the arched spring are connected by a rounded corner.

[0015] The free end of the cantilever structure on the side wall of the socket or the outer side wall of one end of the plug forms a guide slope through a chamfered or warped structure. A V-shaped gap is formed between the guide slope and the outer side wall of one end of the plug or the inner side wall of the socket. This V-shaped gap forms a clearance for the free end of the arched spring to extend into. The free end of the arched spring is inserted into the V-shaped gap through a conical upturned head, ensuring that the free end of the arched spring is smoothly inserted and presses against the side wall of the cantilever structure, forcing it to undergo elastic deformation so that the first and second latches can disengage.

[0016] As a further improvement of the present invention, the separation device further includes a limiting beam, which is fixedly disposed on the side wall of the plug or socket. An annular gap is formed between the limiting beam and the plug or socket to accommodate the expansion and contraction of the free end of the arched spring piece. The outer surface of the free end of the arched spring piece stops against the inner side wall of the annular gap. The limiting beam spans across the arched spring piece to limit and guide it, preventing the arched spring piece from tilting or deflecting, ensuring that it extends into the cantilever structure after being pressed, prying up the cantilever structure, thereby disengaging the first and second latches.

[0017] As a further improvement of the present invention, a protruding hook is formed on the outer wall of the plug or socket, the end size of the protruding hook is larger than the root size, the separation device also includes a square frame-shaped limiting frame, one end of the arched spring is integrally formed on the edge of the limiting frame at one end along the extension direction of the arched spring, the limiting frame forms a limiting beam at the other end along the extension direction of the arched spring, the arched spring is accommodated in the hollow part in the middle of the limiting frame, and an L-shaped groove is formed on each of the two side walls of the limiting frame parallel to the extension direction of the arched spring, the protruding hook on the outer wall of the plug or socket can be locked onto the stepped surface of the L-shaped groove on the two side walls of the limiting frame, and the two ends of the protruding hook on the outer wall of the plug or socket along the length direction of the arched spring are stopped on the two side walls at the two ends of the extension direction of the L-shaped groove. This structure integrally molds the arched spring piece onto the limiting frame, making it a separate part. It is fixedly assembled together by the L-shaped slot and the protruding hook structure, so that the arched spring piece and the limiting frame on it are fixedly installed on the side wall of the plug or socket, which is convenient for installation. Alternatively, it can be integrally molded onto the side wall of the plug or socket, or fixed to the side wall of the plug or socket by screws, snap-fit, heat fusion or other methods. These are equivalent design solutions that can be easily conceived by those skilled in the art based on this patent, and they fall within the scope of protection of this patent.

[0018] As a further improvement of the present invention, a limiting protrusion is fixedly provided on the outer wall of the plug or socket, facing the arched spring piece. The limiting protrusion stops the inner arc side of the arched spring piece. By forming a limiting protrusion on the side wall of the plug or socket, the amount of elastic deformation of the arched spring piece is limited, preventing the arched spring piece from being pressed into permanent deformation.

[0019] The beneficial effects of this invention are as follows: By setting a first latch and a second latch on the socket and plug of the pluggable connector respectively, when the two are plugged in, the first latch and the second latch are engaged together, which prevents the plug and socket from becoming loose when subjected to vibration or external impact, and avoids poor contact or even open circuit. When the plug is pulled out of the socket, the first latch and the second latch can be disengaged by operating the separation device, so that the plug can be pulled out of the socket smoothly, avoiding the situation where it cannot be pulled out. This invention has a novel design and ensures the stability of the pluggable connector. Attached Figure Description

[0030] Example: An improved plug-in connector includes a plug 1 and a socket 2. The plug and socket each include an insulating body and a metal component within the insulating body. When the plug and socket are inserted into each other, the corresponding metal components also make point contact. The plug 1 includes at least one raised locking point 11 and a separation device 3. The socket 2 has at least one elastic cantilever structure 21 on its sidewall. The elastic cantilever structure 21 can open under external force and return to its original position when the external force disappears. The elastic cantilever structure 21 has a hanging platform 22 that can be hung on the raised locking point 11 of the plug to prevent the plug and socket from separating. This hanging platform 22 can be a hole or a barb; the specific structure is not limited, as long as it hooks onto the raised locking point 11 on the plug. The front end of the elastic cantilever structure 21 has a relief portion 23 formed by an inclined surface for the separation device to be inserted to open the elastic cantilever structure 21. The insulating body of the plug also includes a raised hook 12 for fixing the separation device and a limiting protrusion 13. The separation device 3 includes a rectangular limiting frame 31. An arched spring piece 32 is formed in the middle of the rectangular limiting frame. The arched spring piece 32 is parallel to the long side of the rectangular limiting frame. One end of the arched spring piece is connected to one short side of the rectangular limiting frame, and the other side is a free end that passes under the other short side of the limiting frame. The free end of the arched spring piece forms a conical upturned head 33. Inside the long side of the rectangular limiting frame 31, there is a set of L-shaped slots 34. The L-shaped slots 34 and the protruding hooks 12 of the plug 1 are engaged with each other, and the protruding hooks 12 are just locked inside the rectangular limiting frame 31, so that the separation device is completely fixed on the plug 1 and cannot move.

[0031] After the plug and socket are inserted, the socket's mounting bracket 22 hooks onto the protruding locking point 11 on the plug under the elastic force of the elastic cantilever structure 21, preventing the plug and socket from separating. Pressing the arched spring piece 32 of the separation device 3 causes the free end of the arched spring piece 32 to slide forward, and its conical tip 33 inserts into the clearance part 23 of the elastic cantilever structure 21 of the socket. Continuing to press causes the conical tip to slide forward further, thus opening the elastic cantilever structure 21 of the socket, separating the mounting bracket 22 from the protruding locking point 11 of the plug, at which point the plug can be pulled out of the socket. Releasing the arched spring piece 32 on the separation device 3 causes the arched spring piece 32 to drag the conical tip 33 back to its original position under its own elastic force. On the side wall of the plug below the arched spring piece 32 of the separation device 3, a limiting protrusion 13 is designed to limit the downward pressing position of the arched spring piece 32, preventing the arched spring piece from being permanently deformed.
