Description

Technical Field

[0001] The utility model relates to the technical field of light touch switches, in particular to a light touch switch with a waterproof function. Background Art

[0002] A touch switch, also known as a micro switch, is an electronic component designed so that users can control the connection and disconnection of the switch with just a light press. This switch uses an internal metal spring to produce a bouncing action when subjected to force, thereby opening and closing the circuit. The touch switch has many significant advantages, including low contact resistance, high-precision operating force and a variety of specifications. Due to these characteristics, the touch switch has been widely used in various electronic devices and household appliances, such as remote controls, mobile phones, computer keyboards, etc.

[0003] The current touch switches on the market generally have the problem of insufficient sealing performance, which makes it easy for moisture to penetrate into the switch, causing structural damage and eventually causing the switch to fail. In addition, in terms of design, in order to ensure a good sealing effect, the switch button usually uses a sealing ring to fit tightly with the outer wall of the button. However, this design will increase the friction resistance when the button is operated, requiring the user to apply more force to press the button. Not only that, the increased friction will also cause the button to return to its original position slowly after being released, which in turn affects the disconnection accuracy of the switch, reducing its practicality and reliability.

[0004] Therefore, a touch switch with waterproof function is needed to improve the above problems. Utility Model Content

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A light touch switch with waterproof function, comprising a switch base, a limiting protrusion is installed on the opposite side walls of the switch base, a sealing assembly is installed at the port of the switch base, a button is slidably connected to the inner wall of the switch base, a pin is installed on the side wall of the switch base, a spring is installed on the inner wall of the switch base, a cover plate is installed at the port of the switch base, a mounting hole is opened on the outer wall of the cover plate, a sealing sleeve is installed on the inner wall of the mounting hole, a button is slidably connected to the inner wall of the sealing sleeve, an elastic cloth is installed on the outer wall of the sealing sleeve, an arc clamp is installed on the side wall of the cover plate, and the arc clamp is buckled and installed on the outer wall of the limiting protrusion;

[0008] The sealing assembly includes a sealing pad and a mounting plate, the sealing pad is embedded in the port of the switch base, a sealing groove is opened on the base surface of the sealing pad, a sealing gasket is installed on the inner wall of the sealing groove, one end of the sealing gasket is connected to the inner wall of the cover plate, the mounting plate is installed on the side wall of the switch base, a mounting limit sleeve is embedded in the outer wall of the mounting plate, a rotating rod is rotatably connected to the inner wall of the limiting sleeve, a clamping block is installed on the outer wall of the rotating rod, and an arc-shaped protrusion is provided on one side of the cover plate and on the outer wall of the clamping block.

[0009] As a preferred solution of the utility model, the limiting bumps are provided in two groups and are respectively located on opposite outer walls of the switch base, the spring is located directly below the button, and the pins are provided in multiple groups and are respectively located on opposite outer walls of the switch base.

[0010] As a preferred solution of the utility model, the switch base is an integrally formed structure, the button is located in the inner cavity of the elastic cloth, the elastic cloth is made of silicone material, and two groups of sealing grooves are provided and are respectively located on the base surface of the sealing pad.

[0011] As a preferred solution of the utility model, the arc-shaped clamping plates are provided in two groups and are respectively located on opposite side walls of the cover plate, the sealing pad is located directly below the cover plate, and the sealing pad is located on one side of the sealing sleeve.

[0012] As a preferred solution of the utility model, the sealing gaskets are provided in two groups and are respectively located on the inner wall of the cover plate, and the mounting plates are provided in two groups and are respectively located on the opposite outer walls of the switch base.

[0013] As a preferred solution of the utility model, the limiting sleeves are provided in multiple groups and are respectively located on the outer wall of the mounting plate, and the limiting sleeves are located on one side of the switch base.

[0014] As a preferred solution of the utility model, the rotating rods are provided in multiple groups and are respectively located on the inner wall of the limiting sleeve, and the clamping block is a water drop-shaped structure.

[0015] As a preferred solution of the utility model, the arc-shaped protrusion is located between the cover plate and the clamping block, and the height of the arc-shaped protrusion is greater than the height of the gap between the cover plate and the clamping block.

[0016] Compared with the prior art, the utility model provides a sealing gasket in a touch switch with waterproof function, and the cover plate drives the sealing gasket to be embedded in the inner wall of the sealing groove for fixation, and the sealing gasket is installed on multiple groups of sealing grooves for fixation, so that the sealing effect is better, and the clamping block is rotated to make the clamping block drive the rotating rod to rotate on the inner wall of the limit sleeve, so that the clamping block drives the arc-shaped protrusion to move to the top of the cover plate. Since the height of the arc-shaped protrusion is higher than the gap between the cover plate and the clamping block, the arc-shaped protrusion exerts downward pressure on the cover plate, thereby making the cover plate fit more closely to the port of the switch base. At the same time, the connection between the sealing groove and the sealing gasket is tighter, the sealing is better, and better waterproof performance is brought, thereby solving the problem of insufficient sealing performance commonly existing in the touch switches currently on the market, which makes it easy for moisture to penetrate into the inside of the switch, causing structural damage and ultimately causing the switch to fail.

[0017] Because the button is located in the inner cavity of the elastic cloth, its sealing sleeve has a sealing effect on the installation hole. When the elastic cloth made of silicone material is pressed, the elastic cloth is deformed and squeezes the button downward, so that the button slides down on the inner wall of the sealing sleeve. The overall airtightness of the device is better, the sealing sleeve and the button are slidably connected, and the button does not need to fit tightly against the inner wall of the sealing sleeve to ensure that the button is easier to use. The elastic cloth has a sealing effect, thereby solving the problem that the switch button usually uses a sealing ring to fit tightly with the outer wall of the button. However, this design will increase the friction resistance when the button is operated, requiring the user to apply greater force to press the button. Not only that, the enhanced friction will also cause the button to return to its original position slowly after being released, which will affect the disconnection accuracy of the switch and reduce its practicality and reliability.

A sealing gasket 304 is installed on the inner wall of the sealing groove 303. The sealing gasket 304 is provided with two groups and is respectively located on the inner wall of the cover plate 7. One end of the sealing gasket 304 is connected to the inner wall of the cover plate 7. The mounting plate 302 is installed on the side wall of the switch base 1. The mounting plate 302 is provided with two groups and is respectively located on the switch On the outer wall opposite to the base 1, an installation limit sleeve 305 is embedded in the outer wall of the mounting plate 302. The limit sleeve 305 is provided in multiple groups and is respectively located on the outer wall of the mounting plate 302, and the limit sleeve 305 is located on one side of the switch base 1. A rotating rod 306 is rotatably connected to the inner wall of the limit sleeve 305. The rotating rod 306 is provided in multiple groups and is respectively located on the inner wall of the limit sleeve 305. A clamping block 307 is installed on the outer wall of the rotating rod 306. The clamping block 307 is a water drop-shaped structure. An arc-shaped protrusion 308 is provided on one side of the cover plate 7 and on the outer wall of the clamping block 307. The arc-shaped protrusion 308 is located between the cover plate 7 and the clamping block 307, and the height of the arc-shaped protrusion 308 is greater than the gap height between the cover plate 7 and the clamping block 307.

When the clamping block 307 drives the arc-shaped protrusion 308 to move to the outer wall of the cover plate 7, the arc-shaped protrusion 308 exerts downward pressure on the cover plate 7.

[0028] When the touch switch with waterproof function of the present invention is working, the switch base 1 has better overall airtightness due to the integrated structure of the switch base 1. At the same time, the sealing pad 301 is embedded in the port of the switch base 1, and a sealing groove 303 is provided on the base surface of the sealing pad 301. A sealing gasket 304 is installed on the inner wall of the sealing groove 303. One end of the sealing gasket 304 is connected to the inner wall of the cover plate 7. When the cover plate 7 passes through the arc clamping plate 11 and is stuck on the limiting protrusion, the cover plate 7 is locked in the limiting protrusion. 2, its cover plate 7 drives the sealing gasket 304 to be embedded in the inner wall of the sealing groove 303 for fixing.

The height is higher than the gap between the cover plate 7 and the clamping block 307, and the arc-shaped protrusion 308 exerts downward pressure on the cover plate 7, so that the cover plate 7 is more closely fitted to the port of the switch base 1, and at the same time, the connection between the sealing groove 303 and the sealing gasket 304 is tighter, and its airtightness is better, bringing better waterproof performance, thereby solving the problem of insufficient sealing performance of the current touch switches on the market, which makes it easy for moisture to penetrate into the switch, causing structural damage and ultimately causing the switch function to fail.

[0029] A mounting hole 8 is provided on the outer wall of the cover plate 7, a sealing sleeve 9 is installed on the inner wall of the mounting hole 8, a button 4 is slidably connected to the inner wall of the sealing sleeve 9, and an elastic cloth 10 is installed on the outer wall of the sealing sleeve 9. Since the button 4 is located in the inner cavity of the elastic cloth 10, the sealing sleeve 9 has a sealing effect on the mounting hole 8. When the elastic cloth 10 made of silicone material is pressed, the elastic cloth 10 is deformed and squeezes the button 4 downward, so that the button 4 slides downward on the inner wall of the sealing sleeve 9. The overall airtightness of the device is better, the sealing sleeve 9 and the button 4 are slidably connected, and the button 4 does not need to be tightly fitted on the inner wall of the sealing sleeve 9 to ensure that the button 4 is easier to use.
