[0043] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.
[0044] Reference below Figures 1 to 12 A quick connection structure according to an embodiment of the utility model is described.
[0045] According to the quick connection structure of the embodiment of the utility model, it includes a shell 100, a button 200, a conductive component and a spring-pressing member 400. The button 200 is arranged on the shell 100 and is provided with a pressing portion 210; the conductive component is arranged on the shell 100 and includes a plug-in terminal 310 for inserting a wire, and the plug-in terminal 310 is provided with a wire threading hole 311; the spring-pressing member 400 is arranged on the conductive component and includes a spring-pressing portion 410 with elasticity.
[0046] The upper part of the spring-pressing portion 410 extends to correspond to the wire threading hole 311 of the plug-in terminal 310, and the spring-pressing portion 410 can elastically press the wire inserted from the wire threading hole 311 to the conductive component; the upper part of the spring-pressing portion 410 is inclined in a direction away from the wire threading hole 311, and the upper part of the spring-pressing portion 410 is provided with a latch position 411 that can clamp the wire, and the spring-pressing portion 410 is provided with a pressed portion 412 corresponding to the pressing portion 210, and the pressed portion 412 is offset from the latch position 411.
[0047] When in use, the wire is passed through the plug terminal 310 from the wire threading hole 311. Since the upper part of the spring-pressing part 410 is inclined in the direction away from the wire threading hole 311, when the wire passes through the spring-pressing part 410, the spring-pressing part 410 is squeezed to move downward, and the spring-pressing part 410 elastically presses the wire to the conductive component, thereby forming an electrical connection. At the same time, the latch position 411 is used in conjunction with the oblique spring-pressing part 410 to prevent the wire from exiting the plug terminal 310, thereby clamping the wire. When the wire needs to be pulled out, the button 200 is pressed, and the pressing part 210 pushes the pressed part 412, so that the spring-pressing part 410 moves downward, so that the wire is disengaged from the latch position 411, and the wire can be pulled out, thereby realizing quick plug-in of the wire, improving wiring efficiency, facilitating wiring, and meeting wiring operations in a smaller operating space.
[0048] Specifically, Figure 1 , Figure 2 In the socket, the wiring position is located inside the socket, and it is very inconvenient to operate with a screwdriver. By adopting the wiring structure of the utility model, the wiring requirements of this position can be met, and the wiring is simpler.
[0049] In some embodiments of the present invention, the pressed portion 412 and the latching position 411 are staggered to prevent the pressed portion 412 from affecting the normal insertion of the wire.
[0050] Specifically, the pressed portion 412 and the latch position 411 are offset from each other in the projection of the wire insertion direction. When the wire is biased toward the pressed portion 412, the pressing portion 210 of the button 200 can block the insertion of the wire, or guide the wire to deviate (such as by providing a guide surface on the pressing portion 210) to a position corresponding to the latch position 411, so that the wire can be normally plugged in and locked, thereby improving the reliability of the quick wiring structure.
[0051] In some embodiments of the present invention, the wire hole 311 of the plug terminal 310 is aligned with the latch position 411, so that when the wire is inserted forward, it directly enters the position that matches the latch position 411, thereby improving the success rate of wiring.
[0052] like Figures 5 to 8 As shown, in some embodiments of the present invention, the wire is set to be inserted into the plug terminal 310 from front to back, the upper part of the spring-pressing part 410 is inclined toward the rear side, and the latch position 411 is a pointed structure at the upper end of the spring-pressing part 410. When the latch position 411 presses against the wire, it can be partially inserted or stuck on the wire. Since the upper part of the spring-pressing part 410 is inclined toward the rear side, an anti-retraction structure is formed, and the wire is pulled outward to make the wire and the latch position 411 fit more tightly, thereby achieving a loosening effect, the wire is not easy to fall off, and the reliability of wiring is improved.
[0053] Specifically, Figure 7 , Figure 8 As shown, the latching position 411 is the upper section of the spring-pressing portion 410 , and the latching position 411 formed by the sharp angle structure of the edge of the upper section of the spring-pressing portion 410 is used to press the wire.
[0054] like Figure 8 As shown, in some embodiments of the present invention, the latching position 411 is recessed at the upper end of the spring pressing portion 410 to increase its contact with the wire and improve the stability of the wiring.
[0055] Specifically, when the latching position 411 is concave, it can form a longer contact section with the pressed wire, further increasing the wire withdrawal resistance and improving stability.
[0056] like Figures 4 to 8 As shown, in some embodiments of the present invention, the spring-pressing part 400 is a metal plate with a V-shaped structure, one end of the metal plate forms a spring-pressing part 410, and the other end of the metal plate is a connecting part 420, and the connecting part 420 is connected to the conductive component or the shell 100. The top end of the V-shaped structure of the metal plate abuts against the conductive component or the shell 100, and the spring-pressing part 410 is the free end of the metal plate. The metal plate with a V-shaped structure forms a spring pressure, and has certain conductive properties.
[0057] Of course, in the specific implementation process, the elastic member 400 can also be formed by a compression spring and an inclined metal sheet, which will not be described in detail here.
[0058] like Figure 7 , Figure 8 As shown, in some embodiments of the present invention, one end of the metal plate is separated by a dividing groove 401 to form two spring-pressing parts 410, and two wire threading holes 311 corresponding to the spring-pressing parts 410 are arranged on the plug terminal 310, so as to form a double wiring structure to meet different wiring requirements, with a simple structure and good conductive effect of the wires.
[0059] like Figure 7 , Figure 8 As shown, in some embodiments of the present invention, the bottom of the separation groove 401 is an arc-shaped transition groove 402 or a curved transition groove. The arc-shaped transition groove 402 or the curved transition groove reduces the stress concentration during the elastic deformation of the spring-pressing part 410, making it less likely to break, thereby improving the reliability of the wiring structure.
[0060] like Figure 7 , Figure 8 As shown, in some embodiments of the present invention, the pressure-receiving portion 412 of the spring-pressing portion 410 is located on a side close to the dividing groove 401, and the latching position 411 is located on a side of the spring-pressing portion 410 away from the dividing groove 401, that is, the two pressure-receiving portions 412 are close to each other, which is convenient for control by the pressing portion 210 of a single button 200, and the two latching positions 411 are far apart, reducing the occurrence of interference or mis-insertion of the two wires.
[0061] It can be understood that in some embodiments of the present invention, one or more spring-pressing members 400 may be disposed in the plug-in terminal 310 to meet the requirements of multiple wiring.
[0062] In some embodiments of the present invention, the connecting portion 420 is connected to the conductive component via a clamping structure, which facilitates assembly.

[0065] like Figures 4 to 7As shown, in some embodiments of the present invention, a snap-fitting protrusion 421 is provided at the end of the connecting portion 420 , and the extending portion 312 is provided with a snap-fitting groove 313 into which the snap-fitting protrusion 421 can be inserted, so that the connecting portion 420 is snap-fitted to the extending portion 312 .
[0066] like Figure 5 As shown, in some embodiments of the present invention, a concave position corresponding to the top of the V-shaped structure of the metal plate is provided at the bottom of the plug-in terminal 310 to improve the stability of the metal plate when it is installed into the plug-in terminal 310 .
[0067] like Figure 4 , Figure 5 As shown, in some embodiments of the present invention, the conductive component also includes a conductive metal plate 320, and the two ends of the plug-in terminal 310 are respectively connected to the conductive metal plate 320 to form a accommodating space corresponding to the spring-pressing part 400.

[0068] Specifically, connecting protrusions 316 are respectively provided at both ends of the plug-in terminal 310, and holes corresponding to the connecting protrusions 316 are provided in the conductive metal plate 320. The connecting protrusions 316 are inserted into the holes and then bent, thereby connecting both ends of the plug-in terminal 310 to the conductive metal plate 320 respectively.
[0069] It can be understood that in some embodiments of the present invention, both ends of the plug terminal 310 can also be connected to the conductive metal plate 320 by welding, riveting, screw connection, etc.

[0073] Specifically, the plug terminal 310 is in an L-shaped structure, and one open side of the L-shaped structure is blocked by the housing 100 so as to be abutted against the top end of the V-shaped structure of the metal plate.
[0074] like Figure 8 , Fig.12 As shown, in some embodiments of the present invention, a snap-in recess 422 is provided at the end of the connecting portion 420, and a snap-in section 315 is provided at the bending portion 314 for the snap-in recess 422 to be snapped into.
