Description

Technical Field

[0001] The utility model belongs to the technical field of membrane switches, and in particular relates to a waterproof membrane switch panel. Background Art

[0002] Membrane switches have a rigorous structure, beautiful appearance, good sealing, moisture resistance, and long service life. They are widely used in electronic communications, electronic measuring instruments, industrial control, medical equipment, automotive industry, smart toys, household appliances and other fields. They adopt an overall sealing structure composed of a flat multi-layer combination.

[0003] However, the existing waterproof membrane switch panels on the market have some defects during use. Due to the intrusion of moisture, gaps appear in the middle of the laminate, which ultimately affects the use of the membrane switch. To this end, we propose a waterproof membrane switch panel to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a waterproof membrane switch panel to solve the problems existing in the background technology.

[0005] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0006] A waterproof membrane switch panel, comprising a circuit board, a plurality of switch buttons evenly distributed in the middle of the upper end of the circuit board, a membrane board pasted on the upper end of the circuit board, a membrane button corresponding to each of the switch buttons is arranged on the upper end of the membrane board, the membrane board and the membrane buttons can protect the circuit board and each of the switch buttons to prevent water from entering the inside of the circuit board, causing a short circuit of the circuit board and affecting the normal use of the switch buttons, a sealing component is arranged between the circuit board and the membrane board, and the sealing component can further seal the membrane board and the circuit board;

[0007] The sealing assembly includes a sealing strip, an annular groove is opened at the upper end of the circuit board, and each of the switch buttons is located inside the annular groove, and the sealing strip is embedded in the lower end of the film plate, and the sealing strip and the annular groove match each other. After the film plate and the circuit board are adhered together, the sealing strip will be stuck in the annular groove, which can further prevent moisture from affecting the normal use of the switch button.

[0008] A pressing strip is arranged on the upper end of the film plate.

[0009] A plurality of card slots are symmetrically provided at one end of the circuit board opposite to the pressure plate strip, and card blocks corresponding to the card slots are provided at both upper and lower ends of the film board.

[0010] The four corners of the circuit board, the film board and the pressure plate strip are all arranged in arc shapes.

[0011] The four corners of the circuit board, the film board and the pressure plate strip are all provided with mounting holes.

[0012] In the utility model, the sealing strip is inserted into the annular groove, so that when the film plate and the circuit board are pasted together, multiple protective sealing effects can be achieved, thereby preventing moisture from entering the inside of the circuit board and causing a gap between the film plate and the circuit board, which would affect the subsequent use of the switch panel.

[0019] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0020] Embodiment 1:

[0021] like Figure 1-Figure 2 As shown, a waterproof membrane switch panel includes a circuit board 100, a plurality of switch buttons 101 are evenly distributed in the middle of the upper end of the circuit board 100, a membrane plate 102 is attached to the upper end of the circuit board 100, and membrane buttons 103 corresponding to the switch buttons 101 are arranged on the upper end of the membrane plate 102, and a sealing component is arranged between the circuit board 100 and the membrane plate 102;

[0022] The sealing assembly includes a sealing strip 104 . An annular groove 105 is formed at the upper end of the circuit board 100 , and each switch button 101 is located inside the annular groove 105 . The sealing strip 104 is embedded in the lower end of the film plate 102 , and the sealing strip 104 and the annular groove 105 match each other.

[0023] The circuit board 100 contains a circuit, and when the switch button 101 is pressed, a corresponding function is triggered. The film plate 102 is adhered to the upper end of the circuit board 100, which can initially protect the internal circuit and the switch button 101, so that the switch panel can be used normally. The film button 103 can be pressed downward to contact with the switch button 101, thereby allowing the switch panel to operate normally. After the circuit board 100 and the film plate 102 are adhered together, the sealing strip 104 will also be stuck in the corresponding annular groove 105, and the switch button 101 is secondary sealed around, thereby further ensuring that moisture will not contact with the switch button 101 and affect the use of the switch panel;

[0024] During the use of the switch panel: the film plate 102 is pasted on the upper surface of the circuit board 100, which can play a preliminary waterproof effect, and the sealing strip 104 is also stuck in the annular groove 105 to further seal the switch button 101, which can better prevent moisture from affecting the use of the circuit board 100 and the switch button 101;

[0025] In this embodiment, the sealing strip 104 is inserted into the annular groove 105, so that when the film plate 102 and the circuit board 100 are pasted together, multiple protective sealing effects can be achieved, thereby preventing moisture from entering the circuit board 100 and causing a gap between the film plate 102 and the circuit board 100, thereby affecting the subsequent use of the switch panel.

[0026] Embodiment 2:

[0027] Based on the first embodiment, other components on the waterproof membrane switch panel are further described, such as Figure 2-Figure 3 As shown, a pressure strip 200 is provided at the upper end of the film plate 102 .

[0028] A plurality of slots 201 are symmetrically formed at one end of the circuit board 100 opposite to the pressure plate strip 200 , and a clamping block 202 corresponding to each slot 201 is formed at both the upper and lower ends of the film board 102 .

[0029] The four corners of the circuit board 100 , the film board 102 and the pressing plate strip 200 are all configured to be arc-shaped.

[0030] The four corners of the circuit board 100 , the film board 102 and the pressing plate strip 200 are all provided with mounting holes 203 .

[0031] In this embodiment, the pressing strip 200 can press the edge of the film plate 102 to prevent a gap from appearing between the edge of the film plate 102 and the circuit board 100, thereby allowing moisture to enter the inside of the circuit board 100 and thus affecting the normal use of the switch panel;

[0032] When the pressure plate strip 200 is abutted against the upper end of the film plate 102, the pressure plate strip 200 and the circuit board 100 can clamp the film plate 102 to prevent the film plate 102 from falling off and warping, and the clamping block 202 of the film plate 102 will also be clamped into the corresponding clamping groove 201 to prevent the film plate 102 from shaking, thereby affecting the correspondence between the film button 103 and the switch button 101;

[0033] The staff can fix and install the circuit board 100, the film board 102 and the pressure plate strip 200 through the installation holes 203, which can further prevent the switch panel from moving and make it more convenient for people to use.

[0034] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
