[0030] Embodiment: A quick-reset plug-in connector, comprising a socket 1 and a plug 2, wherein a plug connector 11 on the socket 1 can be inserted into a plug hole 21 of the plug 2, a first fastener is formed on the side wall of the plug connector 11 on the socket 1, and an unlocking handle 3 is also installed on the plug 2 in a slidable manner within a set range, one end of the unlocking handle 3 forms a pressing operation end, and a second fastener is provided at the other end of the unlocking handle 3, and an avoidance notch 211 is provided on the side wall of the plug hole 21 of the plug 2, and the second fastener at the other end of the unlocking handle 3 can extend into the plug hole 21 through the avoidance notch 211 and connect with the plug connector 1 inserted into the plug hole 21 1 is buckled and connected with the first buckle on the side wall, the plug 2 is also provided with an elastic member 5 supporting platform 4, the elastic member 5 supporting platform 4 is provided with an elastic member 5 formed by bending a spring sheet or a wire spring, both ends of the elastic member 5 can slide along the surface of the elastic member 5 supporting platform 4, the bent portion 50 in the middle of the elastic member 5 tightly attached to the surface of the elastic member 5 supporting platform 4 is connected to the unlocking handle 3, the bent portion 50 of the elastic member 5 provides the unlocking handle 3 with an elastic retaining force to keep its second buckle in a buckled connection position with the first buckle, and the pressing operation end of the unlocking handle 3 can drive the unlocking handle 3 to overcome the elastic retaining force and slide to disengage the second buckle from the first buckle.
[0031] When the plug 2 is inserted into the socket 1, the plug connector 11 on the socket 1 is simultaneously inserted into the plug hole 21 on the plug 2. When the plug is in place, the unlocking handle 3 on the plug 2 automatically reaches the locked position under the action of the elastic member 5. At this time, the second fastener on the unlocking handle 3 just extends into the plug hole 21 and is snap-connected with the first fastener on the side wall of the plug connector 11. At this time, the plug post and the plug hole 21 are stopped and positioned, and the plug 2 and the socket 1 cannot be separated. When it is necessary to unlock and separate the plug 2 from the socket 1, only the unlocking handle needs to be operated. 3, the unlocking handle 3 overcomes the elastic force of the elastic member 5 and slides toward the unlocking direction. At this time, the second fastener on the unlocking handle 3 is gradually disengaged from the first fastener on the plug post, thereby realizing the disengagement of the plug connector 11 on the socket 1. At this time, the plug 2 can be easily unplugged from the socket 1. When unlocking, the deformation of the bent portion 50 in the middle of the elastic member 5 gradually decreases, and the two ends of the elastic member 5 slide in the opposite direction along the elastic member 5 support platform 4 to adapt to the deformation of the elastic member 5. At this time, the bent portion 50 of the elastic member 5 generates elastic storage force. When the pressing operation end of the unlocking handle 3 is released, the elastic member 5 formed by the bending of the spring sheet or the wire spring restores the original bending state, so that the unlocking handle 3 is automatically reset to the locked position. The elastic member 5 of the utility model is formed by bending a spring sheet or a wire spring. The spring sheet or the wire spring has high bending strength and is not easy to be damaged after long-term use. When the bending portion 50 of the elastic member 5 is compressed and deformed to produce a change in the length direction, the two ends of the elastic member 5 reciprocate along the elastic member 5 support platform 4 for adaptive adjustment to avoid damage to the elastic member 5. The elastic member 5 has a simple structure, occupies a small space, and is low in price, which effectively reduces the cost of the locking structure of the plug 2 and the socket 1. The structure is easy to operate, ensures the electrical connection stability of the plug 2 and the socket 1 when they are plugged in, and facilitates the rapid unlocking and separation of the two. When the plug 2 is separated from the socket 1, no tools are required. Just grab the plug 2 with your hand and press the unlocking handle 3 with your thumb. The plug 2 and the socket 1 can be unlocked. While pressing the unlocking handle 3, pull the plug 2 outward to unplug the plug 2 from the socket 1, which is easy to use.
[0032] The elastic member 5 is an annular structure formed by winding a wire spring at least one circle or a sheet spring. The elastic member 5 of the annular structure is symmetrically bent along the axial mid-plane passing through its axis, and the elastic member 5 of the annular structure is projected on the axial section perpendicular to the axial mid-plane to form a "V"-shaped structure. When the elastic member 5 is wound into a circle using a wire spring, it can be wound one circle or more circles. The elastic member 5 of the annular structure is bent in the middle, and it contacts the elastic member 5 support platform 4 through the circular arc portion. When sliding, the friction force is small and the sliding is smooth. The middle part is connected to the unlocking handle 3 through two symmetrical convex arc surfaces, and the force is stable and the support is stable. The annular elastic member 5 of this application has good elasticity and high strength, and is not easy to be damaged after long-term use.
[0033] The elastic member 5 support platform 4 is provided with a guide column 41, the elastic member 5 of the annular structure is sleeved on the outside of the guide column 41, the unlocking handle 3 is provided with a guide sleeve 31, the guide sleeve 31 can be slidably sleeved on the outside of the guide column 41, and the elastic member 5 of the annular structure is tightly clamped between the elastic member 5 support platform 4 and the end surface of the guide sleeve 31. The guide column 41 cooperates with the guide sleeve 31 to realize the positioning of the elastic member 5 and the guidance of the deformation direction, so as to avoid radial elastic deformation of the elastic member 5 of the annular structure.
[0034] The elastic member 5 is a V-shaped sheet structure formed by bending the middle of the spring sheet, and arc-shaped curling structures 51 are formed at both ends of the length direction of the V-shaped sheet structure, respectively. The arc-shaped curling structures 51 at both ends of the length direction of the V-shaped sheet structure can slide and tightly contact with the elastic member 5 support platform 4, and the unlocking handle 3 is provided with a pressing portion along its sliding direction, and the convex arc surface in the middle of the V-shaped sheet structure is tightly against the surface of the pressing portion on the unlocking handle 3. The middle part of the V-shaped sheet structure can contact with the surface of the pressing portion on the unlocking handle 3 through a plane, and the plane in the middle of the V-shaped sheet structure transitions with the inclined portion of the V-shaped structure through an arc to form a stable support. At the same time, the two ends of the V-shaped sheet structure in the length direction are in contact with the elastic member 5 support platform 4 through the arc-shaped curling structures 51, which can increase the strength of the two ends of the elastic member 5 on one hand, and can also ensure that the two ends of the elastic member 5 slide more smoothly on the elastic member 5 support platform 4.
[0035] The two side walls of the middle part of the elastic member 5 of the V-shaped sheet structure are respectively provided with guide slots 52, and two limit rods 42 are arranged at intervals on the elastic member 5 support platform 4, and the two limit rods 42 can be inserted into the guide slots 52 and can slide relative to each other, and the pressing part on the unlocking handle 3 can be inserted between the two limit rods 42. The above structure can guide the elastic deformation direction of the elastic member 5 of the V-shaped sheet structure, prevent it from being deformed in other directions under pressure, and ensure that the unlocking handle 3 automatically resets after losing external force.
[0036] The plug 2 is provided with a handle slide 22 with one end open and the other end closed, the avoidance notch 211 on the side wall of the plug hole 21 connects the plug hole 21 with the handle slide 22, the unlocking handle 3 can be inserted in the handle slide 22 by sliding a set distance, the pressing operation end of one end of the unlocking handle 3 is exposed to the outside of the plug 2 through the handle slide 22, and the bottom surface of the other end of the handle slide 22 forms an elastic member 5 support platform 4. The unlocking handle 3 is installed inside the plug 2 to protect it.
[0037] The handle slide 22 and the plug hole 21 are staggered and cross vertically, and the side walls of the intersection of the plug hole 21 and the handle slide 22 are connected through an avoidance notch 211. The avoidance notch 211 is located on the side of the intersection and tangency of the plug hole 21 and the handle slide 22, close to the other end of the handle slide 22. The avoidance notch is an arc-shaped notch extending along the circumferential direction of the plug hole 21. The second fastener is fixed on the side wall of the other end of the unlocking handle 3, and the second fastener can be movably inserted in the avoidance notch. When the unlocking handle 3 slides along the handle slide 22, since the boss on the side wall at the other end of the unlocking handle 3 will be located at different positions of the avoidance gap on the side wall of the plug-in hole 21, the closer it is to the plug-in hole 21 and the intersection and tangency position of the handle slide 22, the longer it is inserted into the plug-in hole 21, and vice versa, and it will eventually exit the plug-in hole 21. In addition to the staggered and cross-arranged arrangement of the handle slide 22 with the plug-in hole 21, the slide of the unlocking handle 3 can also be a directly connected structure extending radially along the plug-in hole 21, and the second fastener can be arranged at the other end of the unlocking handle 3. The second fastener can be inserted into or exited from the plug-in hole 21 by sliding the unlocking handle 3 radially along the plug-in hole 21. This is an equivalent replacement structure that can be easily thought of by technicians in this field based on the present application, and it belongs to the protection scope of the present application.
[0038] The first fastener is a circle of annular bosses 111 arranged on the outer wall of the plug connector 11, and the second fastener is an inverted convex block 32. After the annular bosses 111 on the outer wall of the plug connector 11 are inserted into the plug hole 21, they can press against the inclined surface of the second fastener to force the second fastener to overcome the elastic reset force of the elastic member 5 and slide out of the plug hole 21. The second fastener is provided with a blocking surface formed perpendicular to the axial direction of the plug hole 21. The blocking surface on the second fastener can press against the end face of the annular bosses 111 on the outer side of the plug connector 11 that is plugged in place, facing the opening direction of the plug hole 21. The annular bosses 111 are generally arranged at the end of the plug connector 11 of the socket 1, and the blocking surface of the second fastener blocks the annular bosses 111 of the plug connector 11 to achieve sliding resistance of the plug connector 11. In addition, a radial slot can be formed on the plug connector 11, and the second fastener is inserted into the slot of the plug connector 11 to prevent the plug connector 11 from sliding out of the plug hole 21.
[0039] The other end of the unlocking handle 3 is stopped on the bottom surface of the other end of the handle slide 22, and at least two guide grooves 221 extending along the sliding direction of the unlocking handle 3 are evenly spaced on the side wall of the handle slide 22, and a limiting boss structure 222 is provided on the inner side wall of the guide groove 221. At least two guide ribs 33 extending along the sliding direction of the unlocking handle 3 are evenly spaced on the side wall of the unlocking handle 3, and the guide rib 33 can be slidably inserted in the guide groove 221, and a limiting boss 34 of an undercut structure is provided on the guide rib 33, and the limiting boss 34 is stopped on the side wall of the limiting boss structure 222 toward the bottom surface of the other end of the handle slide 22. The guide rib 33 slides in the guide slot 221 to guide the sliding of the unlocking handle 3, ensuring that the second fastener is always in the avoidance gap, preventing the second fastener from slipping out of the avoidance gap. When the unlocking handle 3 is assembled into the handle slide 22, the limiting protrusion 34 on the guide rib 33 contacts the limiting boss in the guide slot 221 through the inclined surface, ensuring that the limiting protrusion 34 smoothly passes over the limiting boss, and finally blocks the limiting boss toward the bottom surface of the handle slide 22 through its plane, thereby limiting the slide distance of the unlocking handle 3.
[0040] The opening at one end of the handle slide 22 forms a countersunk structure 223 with an outwardly expanded size, and a radially outwardly expanded pressing piece 35 is formed on the pressing operation end at one end of the unlocking handle 3. The pressing piece 35 can float up and down and be accommodated in the countersunk structure at one end of the handle slide 22. A concave-convex pattern is formed on the surface of the pressing piece 35. The pressing piece 35 floating in the countersunk structure is not easy to be accidentally unlocked, and at the same time, it is convenient for users to press and unlock with their fingers.
