Description

Technical Field

[0001] The utility model relates to the technical field of light touch switches, in particular to an embedded light touch switch. 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] In order to improve the compactness of the assembly structure, the touch switch is often designed to be embedded, thereby reducing space occupancy and enhancing the density of the overall structure. After a special groove is processed on the equipment, the switch can be simply inserted into the groove for fixation. However, this assembly method may sometimes be not stable enough, which may easily cause the switch to become loose during use, resulting in poor practicality. In addition, during the installation process of the touch switch, most of the pins are currently fixed by welding. During the plug-in and pull-out operations, the solder joints are easily broken due to excessive mechanical stress. Once this happens, repair becomes quite difficult, and the entire switch usually has to be scrapped, which not only increases the maintenance cost, but may also lead to an increase in the overall production cost.

[0004] Therefore, an embedded touch switch is needed to improve the above problems. Utility Model Content

[0005] In order to solve the problem that the touch switch may not be stable enough when embedded, which may easily lead to the switch becoming loose during use and poor practicality, the utility model provides an embedded touch switch to solve the above problem.

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

[0007] A built-in light touch switch comprises a switch base, wherein limiting protrusions are installed on opposite side walls of the switch base, mounting grooves are provided on opposite outer walls of the switch base, a connecting terminal is installed on the inner wall of the mounting groove, one end of the connecting terminal penetrates the switch base and extends to the inner wall of the switch base where a static contact terminal is installed, a fixing block is installed on the inner wall of the mounting groove, a pin sheet is plugged and connected on the inner wall of the fixing block, and the pin sheet is attached to the outer wall of the connecting terminal, a cover plate is installed at the port of the switch base, elastic arc plates are respectively installed on the opposite side walls of the cover plate, limiting grooves are provided on the outer wall of the elastic arc plate, a limiting protrusion is installed on the outer wall of the elastic arc plate, a button is installed on the inner wall of the cover plate, a spring sheet is installed on the inner wall of the switch base, one end of the spring sheet is connected to the connecting terminal, and the other end of the spring sheet is provided with a moving contact terminal.

[0008] As a preferred solution of the utility model, the limiting protrusions are provided in two groups and are respectively located on opposite side walls of the switch base. The cross section of the limiting protrusions is an L-shaped structure, and the limiting protrusions are located on one side of the elastic arc plate.

[0009] As a preferred solution of the utility model, the limiting protrusion is snap-connected to the inner wall of the limiting groove, and the static contact terminal is located directly below the moving contact terminal.

[0010] As a preferred solution of the utility model, the installation grooves are provided in multiple groups and are respectively located on opposite outer walls of the switch base, and the installation grooves are rectangular structures.

[0011] As a preferred solution of the utility model, the connection terminals are provided in two groups and are respectively located on the inner wall of the switch base, and both ends of the connection terminals sequentially penetrate the adjacent installation grooves and are respectively connected to pin pieces.

[0012] As a preferred solution of the utility model, the material of the pin piece is elastic material, and the pin pieces are provided in multiple groups and are respectively located on the inner wall of the mounting groove.

[0013] As a preferred solution of the utility model, one end of the pin piece extends to the outside of the mounting groove, and the shape of the elastic arc plate is an arc structure.

[0014] As a preferred solution of the utility model, the spring sheet is located directly below the button, and when the button slides downward on the inner wall of the switch base, the button applies downward pressure to the spring sheet.

[0015] Compared with the prior art, the utility model provides a pin sheet in the embedded touch switch. When the switch base is inserted into the engaged position, the pin sheet is located in the inner cavity of the mounting groove and one end of the pin sheet protrudes out of the outer side of the mounting groove, so that the pin sheet fits on the contact point. Since the pin sheet is made of elastic material, when squeezed, the pin sheet will be squeezed onto the inner wall of the mounting groove, so that the pin sheet will not be subjected to large mechanical stress during plugging and unplugging, and will not easily break. The practicality of the device is better, thereby solving the problem that most pins are currently fixed by welding. During the plugging and unplugging operation, the solder joints are easily broken due to excessive mechanical stress. Once this happens, repair becomes quite difficult, and the entire switch usually has to be scrapped, which not only increases the maintenance cost, but may also lead to an increase in the overall production cost.

[0016] When the switch base is embedded and inserted into the groove of the installation position, the outer side of the elastic arc plate is deformed by the extrusion force, and the elastic arc plate is deformed and fits on the inner wall of the groove. Since the limiting convex plate is located at one end of the elastic arc plate, when the elastic arc plate is deformed, the one end of the elastic arc plate drives the limiting convex plate to move outward, so that the limiting convex plate is clamped on the inner wall of the groove for fixation, and the elastic arc plate is clamped on the outer wall of the limiting convex block to install the cover plate. At the same time, the elastic arc plate is deformed and fits on the inner wall of the groove for fixation, thereby improving the stability of the switch when embedded, thereby solving the problem that after a special groove is processed on the equipment, the switch can be simply clamped into the groove for fixation. However, this assembly method may sometimes be not stable enough, which can easily cause the switch to loosen during use, resulting in poor practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In this embodiment, specific reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , two groups of limiting protrusions 2 are provided and are respectively located on the opposite side walls of the switch base 1, the cross-section of the limiting protrusion 2 is an L-shaped structure, and the limiting protrusion 2 is located on one side of the elastic arc plate 9, the limiting protrusion 2 is snap-connected to the inner wall of the limiting groove 10, the static contact terminal 5 is located directly below the moving contact terminal 14, the mounting groove 3 is provided with multiple groups and is respectively located on the opposite outer walls of the switch base 1, and the mounting groove 3 is a rectangular structure, two groups of connecting terminals 4 are provided and are respectively located on the inner wall of the switch base 1, and the two ends of the connecting terminal 4 sequentially penetrate the adjacent mounting grooves 3 and are respectively connected with pin sheets 7, the material of the pin sheet 7 is an elastic material, and the pin sheet 7 is provided with multiple groups and is respectively located on the inner wall of the mounting groove 3, one end of the pin sheet 7 extends to the outside of the mounting groove 3, the shape of the elastic arc plate 9 is an arc structure, the spring sheet 13 is located directly below the button 12, and when the button 12 slides downward on the inner wall of the switch base 1, the button 12 applies downward pressure to the spring sheet 13.

[0026] In which, downward pressure is applied to the button 12, so that the button 12 slides up and down on the inner wall of the switch base 1. At the same time, the button 12 applies downward pressure to the spring 13, so that the spring 13 is displaced and deformed, and the moving contact terminal 14 at one end of the spring 13 is attached to the outer wall of the static contact terminal 5 to achieve the connection of the device circuit. Similarly, when the button 12 is released, the deformed spring 13 is restored, so that the moving contact terminal 14 and the static contact terminal 5 are disconnected.

Because the pin piece 7 is located in the inner cavity of the mounting groove 3, and one end of the pin piece 7 protrudes from the outside of the mounting groove 3 , so that the pin piece 7 fits on the contact point. Since the pin piece 7 is made of elastic material, when it is squeezed, the pin piece 7 will be squeezed onto the inner wall of the mounting groove 3, so that the pin piece 7 will not be subjected to large mechanical stress during plugging and unplugging, and is not easy to break. The practicality of the device is better, thereby solving the problem that most pins are currently fixed by welding. During the plugging and unplugging operation, the solder joints are prone to breakage due to excessive mechanical stress. Once this happens, repair becomes quite difficult, and the entire switch usually has to be scrapped, which not only increases the maintenance cost, but may also lead to an increase in the overall production cost.

A limiting groove 10 is provided on the outer wall of the elastic arc plate 9, and a limiting convex plate 11 is installed on the outer wall of the elastic arc plate 9. The shape of the elastic arc plate 9 is an arc-shaped structure. When the switch base 1 is inserted into the groove at the installation position, the outer side of the elastic arc plate 9 is deformed by the extrusion force, and the elastic arc plate 9 is deformed and fits on the inner wall of the groove. Since the limiting convex plate 11 is located at one end of the elastic arc plate 9, when the elastic arc plate 9 is deformed, When the switch is shaped, one end of the elastic arc plate 9 drives the limiting convex plate 11 to move outward, so that the limiting convex plate 11 is stuck on the inner wall of the groove for fixation, and the elastic arc plate 9 is stuck on the outer wall of the limiting convex block 2 to install the cover plate 8. At the same time, the elastic arc plate 9 is deformed and fits on the inner wall of the groove for fixation, thereby improving the stability of the switch when embedded, thereby solving the problem that after a special groove is processed on the equipment, the switch can be simply stuck into the groove for fixation. However, this assembly method may sometimes be not stable enough, which may easily cause the switch to become loose during use, and has poor practicality.
