DETAILED DESCRIPTION

[0032] The following embodiments are combined with the accompanying drawings to further illustrate the specific implementation of the switch non-disassembly structure and the switch of the present utility model. The switch non-disassembly structure and the switch of the present utility model are not limited to the description of the following embodiments.

[0033] like Figure 1-Figure 3As shown, the switch of this embodiment includes a switch non-disassembly structure, which includes a base 6, a panel 2 and a cover plate 1, wherein the panel 2 is located between the base 6 and the cover plate 1, and the switch also includes a conductive system 5 installed in the base 6, a pressure plate 4 and a button assembly 3, wherein the conductive system 5 is installed in the base 6, the pressure plate 4 covers the base 6 to fix the conductive system 5, and the button assembly 3 passes through the pressure plate 4 to drive the movable contact assembly 52 of the conductive system 5. Figure 7 As shown, the conductive system 5 is made of copper or other conductive materials, including a moving contact assembly 52, a conductive assembly 53 electrically connected to the moving contact assembly 52, and two symmetrically arranged static contact assemblies 51. The static contact assembly 51 is provided with a static contact 511. The moving contact assembly 52 is a swing-piece structure located between the two static contact assemblies 51. The moving contact assembly 52 is provided with two moving contacts 521 corresponding to the static contacts 511 of the two static contact assemblies 51. Both the moving contacts 521 and the static contacts 511 have a graphene coating made of electroplated graphene. The conductive system 5 adopts a double-contact structure, including two groups of matching moving contacts 521 and static contacts 511. When the moving contact assembly 52 swings to a point where one group of moving contacts 521 and static contacts 511 are closed, the other group of moving contacts 521 and static contacts 511 are disconnected. Figure 8 As shown, the button assembly 3 includes a button 30 and a spring 33 connected between the button 30 and the moving contact assembly 52. ​​The button 30 is rotatably mounted on the pressure plate 4. The cover plate 1 of the switch non-disassembly structure can drive the button 30 to drive the moving contact assembly 52, so that the moving contact 521 and the static contact 511 are disconnected or closed.

[0034] Specifically, Figure 3 and Figure 8As shown, the button 30 has a button cross bar and a button vertical bar connected to the middle of the bottom surface of the button cross bar. The two ends of the button cross bar are lower than the middle of the button cross bar to form the swing arm 31 of the button 30. The bottom surface of the cover plate 1 is provided with two pressure ribs 13 driving and cooperating with the two swing arms 31 of the button 30. The connection between the button cross bar and the button vertical bar is provided with two button shafts 32 located on both sides; one end of the spring 33 is placed in the spring cavity of the button vertical bar, and the other end is connected to the moving contact assembly 52. ​​It should be noted that the driving structure and action principle between the button assembly 3 and the swing-piece moving contact assembly 52 of this embodiment are prior art, which will not be repeated here. The utility model can not only adopt the button assembly 3 and the swing-piece moving contact assembly 52 of this embodiment, but also other structures such as the button assembly and bridge-type moving contact assembly composed of a button, a spring and a top rod. The conductive system 5 may also be provided with only one stationary contact assembly 51, and the moving contact assembly 52 may be provided with only one moving contact 521. The button 30 may be rotatably installed, and the cover plate 1 may drive the button 30 to drive the moving contact assembly 52, so that the moving contact 521 is disconnected or closed with the stationary contact 511. The moving contact 521 and the stationary contact 511 may also not be provided with a graphene coating.

[0035] like Figure 4 As shown, in the switch disassembly-free structure of the present embodiment, the panel 2 is detachably mounted on the base 6, the cover plate 1 is rotatably mounted on the panel 2, the panel 2 is provided with a cover plate rotating shaft 21, the cover plate 1 is provided with a buckle foot 11, the buckle foot 11 is provided with a mounting hole 12 that is rotatably matched with the cover plate rotating shaft 21, and the mounting hole 12 is matched with the cover plate rotating shaft 21 in the radial upper limit position of the cover plate rotating shaft 21 so that the cover plate 1 is limitedly mounted on the panel 2. The switch disassembly-free structure and the switch of the present embodiment, by rotatably and limitedly mounting the cover plate 1 on the panel 2 instead of on the base 6, does not require the cover plate 1 to be disassembled when installing the switch, but only requires the panel 2 to be disassembled for installation, so that the buckle foot 11 of the cover plate 1 is not easily damaged, and the stability of the switch operation feel is ensured. Since the cover plate 1 has a decorative function and a function of driving the button 30, disassembly may easily lead to deformation, affecting the appearance and the cooperation with the button 30; while the panel 2 is blocked by the cover plate 1 and mainly plays a role of installation and fixing, and some deformation after removal does not affect the appearance and use. The switch of this embodiment only needs to remove the panel 2 to be installed, protecting the cover plate 1, ensuring the appearance of the switch and the stability of the operating feel. The detachable installation structure of the panel 2 can adopt a snap-fit ​​structure between the buckle on the inner side of the panel 2 and the slot on the outer side of the base 6 or other detachable structures.

[0036] like Figure 4 and Figure 5As shown, the specific structure of the mounting hole 12 of the present embodiment, the mounting hole 12 is a non-closed structure, including a connected circular hole 121 and a mounting entrance 122, the mounting entrance 122 has two limiting side walls 123 which are respectively connected to the side walls of the circular hole 121 and arranged opposite to each other, the circular hole 121 is rotatably matched with the cover plate shaft 21, and the distance between the two limiting side walls 123 is smaller than the outer diameter of the cover plate shaft 21, so that the side wall of the circular hole 121 is matched with the cover plate shaft 21 at the radial upper limit of the cover plate shaft 21 at the connection with the limiting side wall 123, so that the cover plate shaft 21 is not easy to escape from the circular hole 121. It is worth mentioning that the cover plate 1 is usually made of plastic, and the buckle foot 11 of the cover plate 1 is integrally formed with the cover plate 1 and has a certain elasticity, so that when the cover plate shaft 21 passes through the installation entrance 122, it squeezes the two limiting side walls 123 to increase the distance between the two limiting side walls 123, so that the cover plate shaft 21 can pass through the installation entrance 122 and enter the circular hole 121. Of course, as other embodiments, the installation hole 12 can also be a closed circular hole structure.

[0037] Furthermore, the two limiting side walls 123 are inclined, and the distance between the two limiting side walls 123 decreases in the direction away from the circular hole 121, so that the cover plate shaft 21 is not easy to escape from the circular hole 121, and the stability and reliability of the cover plate 1 installed on the panel 2 are further improved. Preferably, the installation entrance 122 has two guide side walls 124 respectively connected to the two limiting side walls 123 and arranged oppositely, and the two guide side walls 124 are inclined, and the distance between the two guide side walls 124 increases in the direction away from the circular hole 121, so that the installation operation of the cover plate 1 on the panel 2 is simpler and less laborious. Optionally, a groove 125 opposite to the installation entrance 122 is provided on the side wall of the circular hole 121. The provision of the groove 125 increases the deformability of the buckle foot 11, so that the cover plate shaft 21 can pass more smoothly between the two limiting side walls 123 of the installation entrance 122 and enter the circular hole 121 during installation.

[0038] like Figure 4 and Figure 6 As shown, a bridge plate 22 is integrally formed on the middle of the panel 2, and the length direction of the bridge plate 22 is parallel to the axial direction of the cover plate shaft 21. The panel 2 is provided with two cover plate shafts 21 located on both sides of the length direction of the bridge plate 22, and the cover plate 1 is provided with two buckle feet 11 corresponding to the two cover plate shafts 21. A bridge plate 22 is provided in the middle of the panel 2 to support the cover plate 1, which can increase the strength of the panel 2, prevent deformation, and make the switch operation feel better. Preferably, a disassembly port 24 is provided on the side of the panel 2 as the operating position of a disassembly tool such as a screwdriver to facilitate the disassembly of the panel 2.

[0039] like Figure 3-Figure 6As shown, the bridge plate 22 is provided with two avoidance holes 23 corresponding to the two pressure ribs 13 on the bottom surface of the cover plate 1. The pressure ribs 13 of the cover plate 1 pass through the avoidance holes 23 and extend into the base 6 to drive and cooperate with the swing arm 31 of the switch button 30. In this embodiment, the button 30 is rotatably mounted on the pressure plate 4 through the button shaft 32.

[0040] Preferably, as another embodiment, the button 30 is rotatably mounted on the panel 2 via a button shaft 32, preferably mounted on a raised bridge plate 22 of the panel 2. Compared with a panel 2 rotatably mounted on a pressure plate 4 or without a bridge plate 22, the rotation axis of the button 30 is higher, and the cover plate 1 only needs to swing a very small angle to drive the moving contact assembly 52 to swing a larger distance.

[0041] In the assembly process of the switch of this embodiment, the conductive system 5 is installed into the base 6, and then the button assembly 3 is first installed into the pressure plate 4, and then the pressure plate 4 is installed on the base 6, so as to firmly press the conductive system 5; the two buckle feet 11 of the cover plate 1 are buckled onto the two cover plate rotating shafts 21 of the panel 2. At this time, the cover plate 1 and the panel 2 are assembled into an integral cover plate 1 and panel 2 assembly, and the pressure rib 13 on the cover plate 1 passes through the avoidance hole 23, and then the cover plate 1 and panel 2 assembly is installed on the base 6, and the pressure rib 13 on the cover plate 1 passes through the avoidance hole 23 and contacts the swing arm 31 of the button assembly 3, and the switch assembly is completed.

[0042] When the switch needs to be installed at a usage location, such as a wall, use a tool to remove the panel 2 from the base 6 through the disassembly opening 24. Since the cover 1 is buckled on the panel 2, the cover 1 is removed together with the panel 2 at this time, that is, the cover 1 and panel 2 assembly is removed from the base 6 without removing the cover 1 separately. Then, the switch base 6 is fixed to the wall with mounting screws, and then the panel 2 is buckled on the base 6, that is, the cover 1 and panel 2 assembly is reinstalled on the base 6. At this time, the switch installation is completed.
