Description

Technical Field

[0001] The utility model relates to the field of electricity, in particular to a push-button switch, and more particularly to a connection structure for a push-button switch. Background Art

[0002] The push-button switch is a commonly used component in the field of electricity. In the prior art, the installation method of the head of the push-button switch and the middle seat is through the sliding of a clamping plate. The clamping plate pushes the middle seat to deform, so that the head disengages from the clamping position of the middle seat, and then the head is pulled out; the installation process is the opposite. When the head is pressed, the clamping position of the middle seat deforms to give way, and the head groove coincides with the clamping position of the middle plate. In this solution, the deformation of the clamping position of the middle seat is easily affected by plastic aging and does not rebound, resulting in the head being easily detached and the button failing. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a connection structure for a push-button switch. The connection structure for a push-button switch is to solve the technical problem that the connection fastener of the push-button switch in the prior art fails due to plastic aging.

[0004] To achieve the above purpose, the utility model provides the following technical solutions:

[0005] A connection structure for a push-button switch includes a cylindrical plug-in. A chute is arranged on the side wall surface of the plug-in. The chute is wedge-shaped. The hypotenuse of the chute is connected to a clamping groove. A guiding groove is arranged on the side wall surface. The guiding groove is arranged parallel to the axial direction of the plug-in.

[0006] It further includes a middle seat. A first through hole is arranged in the middle of the middle seat. A slot is arranged on the side wall of the middle seat. The length direction of the slot is perpendicular to the axial direction of the first through hole. A guiding block is arranged on the inner wall surface of the first through hole. The number and position of the guiding blocks are respectively arranged in cooperation with the guiding grooves.

[0007] It further includes an insertion piece. A second through hole is arranged in the middle of the insertion piece. A wedge-shaped clamping block is arranged on the inner wall surface of the second through hole. The number and position of the clamping blocks are respectively arranged in cooperation with the chutes.

[0008] The insertion piece is arranged in the slot. A reset mechanism is arranged between the front end of the insertion piece and the inner wall of the slot. The second through hole and the first through hole are coaxially arranged. The plug-in passes through the first through hole and the second through hole. The guiding block is arranged in the guiding groove, and the clamping block is arranged in the clamping groove.

[0009] Further, the reset mechanism includes a first positioning post and a second positioning post. The first positioning post is arranged at the front end of the insertion piece, and the second positioning post is arranged on the inner wall surface of the card slot. The first positioning post and the second positioning post are coaxially arranged. A spring is also included, and both ends of the spring are respectively sleeved on the outer circumferences of the first positioning post and the second positioning post.

[0010] Further, the length direction of the card slot is perpendicular to the axial direction of the plug-in component.

[0011] Further, the number of the sliding grooves is two, and they are symmetrically arranged on both sides of the plug-in component along the axis of the plug-in component.

[0012] Working principle:

[0013] The upper part of the plug-in component is connected to the button head, and the bottom of the middle seat is connected to the module base. Insert the insertion piece into the slot, and then insert the plug-in component with the button head into the middle seat, and the assembly of the push-button switch can be completed.

[0014] In the utility model, the wedge-shaped sliding groove on the plug-in component guides the clamping block on the insertion piece to slide into the card slot connected to the sliding groove, realizing the limit of the insertion piece to the plug-in component, thereby ensuring the reliable connection of the push-button switch.

[0015] Compared with the prior art, the beneficial effects of the utility model are: the connection relationship is reliable and stable, the installation and removal operations are convenient, and the failure condition will not occur. Brief description of the drawings

[0020] Embodiment 1

[0021] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , the utility model provides a technical solution:

[0022] A connection structure for a push-button switch, including a cylindrical plug-in 1. A chute 11 is provided on the side wall surface of the plug-in 1. The chute 11 is wedge-shaped, and the hypotenuse of the chute 11 is connected to a card slot 12. A guiding groove 13 is provided on the side wall surface, and the guiding groove 13 is arranged parallel to the axis of the plug-in 1.

[0023] It also includes a middle seat 2. A first through hole 21 is provided in the middle of the middle seat 2. A slot 22 is provided on the side wall of the middle seat 2. The length direction of the slot 22 is perpendicular to the axis of the first through hole 21. A guiding block 23 is provided on the inner wall surface of the first through hole 21. The number and position of the guiding blocks 23 are respectively arranged in cooperation with the guiding grooves 13.

[0024] It further includes a inserting piece 3. A second through hole 31 is provided in the middle of the inserting piece 3. A wedge-shaped locking block 32 is provided on the inner wall surface of the second through hole 31. The number and position of the locking blocks 32 are respectively arranged in cooperation with the chutes 11.

[0025] The inserting piece 3 is arranged in the slot 22. A reset mechanism is provided between the front end of the inserting piece 3 and the inner wall of the slot 22. The second through hole 31 and the first through hole 21 are coaxially arranged. The plug-in 1 passes through the first through hole 21 and the second through hole 31. The guiding block 23 is arranged in the guiding groove 13, and the locking block 32 is arranged in the card slot 12.

[0026] Further, the reset mechanism includes a first positioning post 41 and a second positioning post 42. The first positioning post 41 is arranged at the front end of the inserting piece 3. The second positioning post 42 is arranged on the inner wall surface of the card slot 12. The first positioning post 41 and the second positioning post 42 are coaxially arranged. It also includes a spring 4. The two ends of the spring 4 are respectively sleeved on the outer circumferences of the first positioning post 41 and the second positioning post 42.

[0027] Further, the length direction of the card slot 12 is perpendicular to the axis of the plug-in 1.

[0028] Further, the number of the chutes 11 is two, and they are symmetrically arranged on both sides of the plug-in 1 along the axis of the plug-in 1.

[0029] Working process:

[0030] During installation, the upper part of the plug-in 1 is connected to the button head, and the bottom of the middle seat 2 is connected to the module base. Insert the insert piece 1 into the slot 22, and then insert the plug-in 1 with the button head into the middle seat 2. During this process, because the wedge-shaped chute 11 is wider at the bottom than at the top, the wedge-shaped inclined surface of the wedge-shaped chute 11 interacts with the locking block 32, pushing the insert piece 3 to slide into the slot 22, compressing the spring 4. When the locking block 32 passes the high point of the wedge-shaped inclined surface and slides to the entrance of the card slot 12, the spring 4 rebounds, pushing the locking block 32 into the card slot 12, making the plug-in 1 unable to move up and down. In this way, the assembly of the button switch can be completed. The cooperation of the guiding groove 13 and the guiding block 23 ensures that the plug-in 1 has a stable path during insertion and does not rotate circumferentially.

[0031] During disassembly, press the insert piece 3 deep into the slot 22 to compress the spring 4. At the same time, the locking block 32 on the insert piece 1 slides out of the card slot 12, and then the button head and the plug-in 1 can be pulled out upward.
