Some embodiments of the present utility model are described in detail below with reference to fig. 1 to 5. The following embodiments and features of the embodiments may be combined with each other without conflict.

Referring to fig. 1 and 2, the electronic switch includes a holder 10, a power board 20, a pressing board 30, a control board 40, a panel 50, and buttons 60.

The fixing frame 10 is mainly used as a bearing main body for fixing the power panel 20, the pressing plate 30, the control panel 40 and the panel 50, and the fixing frame 10 is used for being arranged on a wall body, a table body and other parts.

The power panel 20 is located in the fixing frame 10, and the pressing plate 30 is pressed on the power panel 20 and connected with the fixing frame 10 through screws, so that the power panel 20 is fixed in the fixing frame 10.

The outer frame of the panel 50 and the fixing frame 10 can be connected in a snap-fit manner, the control board 40 is located between the pressing board 30 and the panel 50, the control board 40 is pressed on the panel 50 by the pressing board 30, the button 60 is connected to the outer frame of the panel 50, and a user can touch the micro switch 41 on the control board 40 to switch on or off by pressing the button 60.

In the prior art, in order to fasten the connection between the pressing plate 30 and the panel 50 to compress the control board 40 therebetween, a countersunk hole 51 is provided in the middle area of the panel 50, a through hole corresponding to the countersunk hole 51 is provided in the middle area of the control board 40, and a threaded hole corresponding to the through hole is provided in the middle area of the pressing plate 30, so that a screw passes through the countersunk hole 51 and the through hole and then is locked into the threaded hole, so that the panel 50 and the pressing plate 30 are connected to compress the control board 40.

However, since the fixing frame 10 is generally fixed to an object such as a wall body, a seat body, etc. through the mounting holes 11 by using the mounting screws, the fixing frame 10 is deformed to be downwardly recessed due to the pressing of the mounting screws during the locking of the fixing frame 10 by the mounting screws, and simultaneously, the power board 20 and the pressing board 30 locked by the screws are downwardly recessed as the fixing frame 10 is downwardly recessed due to the mounting of the pressing board 30 and the power board 20 on the fixing frame 10 by the screws. Meanwhile, since the pressing plate 30 is connected with the panel 50 through the screw, the pressing plate 30 can pull the middle part of the panel 50 to sink through the screw, the frame part is tilted, so that the clamping force applied to the control board 40 between the panel 50 and the pressing plate 30 is insufficient, the panel 50, the control board 40 and the pressing plate 30 cannot be completely locked, further, shaking abnormal sound is generated, and in addition, the sinking of the middle area of the panel 50 can cause the increase of the distance between the button 60 connected to the outer frame of the panel 50 and the micro switch 41 on the control board 40, so that the micro switch 41 cannot be effectively touched when the button 60 is pressed, the problem of product function failure is caused, and the use experience of a customer is affected.

Based on the above-described drawbacks, the inventors have studied to provide an embodiment of a connection structure for improvement. The panel 50, the control board 40 and the pressing plate 30 are connected by a connecting structure.

Wherein, since the connecting body 310 is connected to the pressing plate 30 through the elastic portion 311, the elastic force provided by the elastic portion 311 can enable the connecting body 310 to have a trend of moving along the thickness direction of the pressing plate 30 relative to the pressing plate 30, so that even if the fixing frame 10 is deformed due to the downward sinking of the fixing frame due to the locking of the screw, the connecting body 310 is connected with the locking member 70 to enable the elastic portion 311 to be elongated, thereby avoiding the sinking of the middle portion of the panel 50 by the locking member 70, and the control board 40 can be locked by the locking member 70 and the connecting body 310 to avoid the generation of shaking abnormal sound, and simultaneously, the sinking of the middle portions of the control board 40 and the panel 50 can be avoided, so that the push button 60 can effectively contact the micro switch 41 when being pressed, thereby ensuring the normal use of the switch product function.

In addition, in the assembly process of the electronic switch product of the related art, in order to secure the assembly efficiency of the product, the product is conventionally assembled such that parts are sequentially stacked from the fixing frame 10 and are locked by a fastening position or a screw. However, in order to ensure that the control board 40 can be firmly locked on the panel 50, the switch product is assembled in a flip-chip order, that is, the panel 50, the control board 40 and the pressing board 30 are locked by screws, and then the pin 42 in the control board 40 is combined with the pin 21 in the power board 20, so that the assembly of the product is completed. In the installation mode, the pin 42 is easily damaged due to the fact that the pin 42 cannot be accurately connected in the assembly process of the pin 21, so that the product is damaged and scrapped.

In this embodiment, by providing the connection structure, the switch product can be installed in the forward direction, that is, the power panel 20 is assembled to the fixing frame 10 by the pressing plate 30, then the control panel 40 and the panel 50 are sequentially prevented from being sequentially arranged on the pressing plate 30, after the outer frame of the panel 50 is buckled with the fixing frame 10, the locking member 70 passes through the middle area of the panel 50 and the control panel 40 and then is locked into the connection body 310, so that the assembly yield and efficiency of the row of the pins 42 and the row of the nuts 21 can be ensured.

Referring to fig. 3 and 4, in the present embodiment, the pressing plate 30 is provided with a through hole 32, and the connection body 310 is disposed through the through hole 32 and connected to the pressing plate 30 through the elastic portion 311, so that the total thickness of the connection body 310 and the pressing plate 30 can be reduced, thereby ensuring the consistency of the overall thickness dimension of the switch and the thickness dimension of the conventional product.

Specifically, the elastic portion 311 has a strip-shaped structure, a first end thereof is connected to the connecting body 310, a second end thereof is connected to the inner wall of the through-hole 32, and the first end and the second end are opposite ends of the elastic portion 311 respectively. So set up the elastic part 311 to the strip structure, elastic deformation takes place more easily in the elastic part 311 to the elastic part 311 is less through the pulling force of connecting main part 310 downward pulling control panel 40 when clamp plate 30 sinks, in order to better avoid the middle part of panel 50 to take place towards clamp plate 30 indent, moreover, because the second end of elastic part 311 is the inner wall that is connected to through-hole 32, consequently can avoid because the connection setting of elastic part 311 leads to the problem of clamp plate 30 thickness increase.
