Description

Technical Field

[0001] This utility model relates to the field of electronic membrane switches, specifically a voltage-resistant electronic membrane switch. Background Technology

[0002] A membrane switch is an integrated operating system combining button functions, indicator elements, and an instrument panel. It consists of four parts: the panel, upper circuit, isolation layer, and lower circuit. When the membrane switch is pressed, the contacts in the upper circuit deform downwards, making contact with the plates in the lower circuit to conduct electricity. When the finger is released, the contacts in the upper circuit rebound, the circuit breaks, and the circuit triggers a signal. Membrane switches are characterized by their robust structure, aesthetic appearance, good sealing, moisture resistance, and long service life.

[0003] According to Chinese Patent No. CN217086437U, a pressure-resistant electronic membrane switch is disclosed. By setting a pressure-resistant mechanism on the surface of the membrane switch and the button, after the rubber frame, connecting strip and rib of the pressure-resistant mechanism are bonded to the surface of the membrane switch, the rubber pad between the ribs presses on the top of the button. At this time, the adhesive patch at the groove below the rubber pad is bonded to the surface of the button. At this time, the pressure-resistant mechanism is fixed on the surface of the membrane switch and the button. When the rubber pad is pressed by hand, the soft contact surface under the rubber pad and the soft adhesive patch press the button, thereby avoiding damage to the button from external pressure and friction, and improving the pressure resistance life of the button on the surface of the membrane switch.

[0004] Regarding the aforementioned patent content, a rubber disc is provided to shield and protect the buttons on the membrane switch and improve the pressure resistance of the membrane switch. However, after the rubber disc is pressed for a long time, it may be damaged or its pressure resistance may be reduced. At this time, the rubber disc needs to be replaced. However, multiple rubber discs are integrated with the rubber frame, which means that when a rubber disc is damaged, the entire rubber frame needs to be replaced, which increases the replacement cost. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a pressure-resistant electronic membrane switch to solve the technical problem of difficulty in disassembling and replacing individual rubber discs.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pressure-resistant electronic membrane switch, comprising a membrane switch body, a rubber frame bonded to the outer surface of the membrane switch body, a horizontal bar installed inside the rubber frame, and multiple connecting strips detachably disposed between the horizontal bar and the inner wall of the rubber frame, a disassembly assembly provided on the rubber frame and the horizontal bar, and the disassembly assembly including multiple positioning grooves opened on the outer surface of the horizontal bar and the outer surface of the rubber frame, multiple sliding grooves opened at the bottom and top of the horizontal bar and the upper and lower interior of the rubber frame, and a positioning block installed on the connecting strips, a spring installed inside the sliding groove, and a movable block connected to one end of the spring, a slot opened on one side of the positioning block, and a locking block extending into the slot installed on one side of the movable block.

[0007] By adopting the above technical solution, once the card block is removed from the card slot, it no longer clamps and limits the positioning block. In this way, the connecting strip and the rubber disc can be removed so that the damaged rubber disc can be replaced.

[0008] Furthermore, a pusher is installed on one side of the movable block that extends to the outside of the slide groove.

[0009] By adopting the above technical solution, it is convenient for staff to push the movable block to move, so that the movable block can drive the card block to move.

[0010] Furthermore, a rubber tray is connected between every two connecting strips, and an adhesive patch is provided on the back of the rubber tray. The crossbar is bonded and fixed to the membrane switch body.

[0011] By adopting the above technical solution, the rubber disc can protect the buttons.

[0012] Furthermore, multiple buttons are also installed on the outer surface of the membrane switch body.

[0013] By adopting the above technical solution, staff can press buttons to operate the membrane switch.

[0014] Furthermore, each button corresponds to a rubber disc, and the adhesive patch is bonded to the button.

[0015] By adopting the above technical solution, when a person presses the rubber plate, a soft contact surface under the rubber plate, together with a soft adhesive patch, presses the button, thereby avoiding damage to the button from pressure and friction caused by external objects, and improving the pressure resistance life of the button on the membrane switch surface.

[0016] Furthermore, a DuPont wire is connected to the top of the membrane switch body, and a plug is connected to the top of the DuPont wire.

[0017] By adopting the above technical solution, the combination of DuPont wires and plugs enables the membrane switch to be connected to an external circuit.

[0018] Furthermore, both the rubber disc and the connecting strip are detachably connected to the rubber frame via positioning blocks.

[0019] By adopting the above technical solution, it is convenient to disassemble and replace the rubber disc and connecting strip.

[0020] Furthermore, the positioning block is adapted to the positioning groove.

[0021] By adopting the above technical solution, the connecting strip and the rubber disc can be positioned after the positioning block is inserted into the positioning groove.

[0022] Furthermore, the card block is adapted to the card slot, and the card block is slidably connected to the slide groove via a movable block.

[0023] By adopting the above technical solution, once the card block is inserted into the card slot, the positioning block can be clamped and limited to prevent it from falling out of the positioning slot.

[0024] In summary, the present invention has the following main advantages:

[0025] This invention features a disassembly and assembly component. When the rubber disc is damaged due to prolonged pressure, it needs to be disassembled and replaced. The operator pushes a locking block to move it. Once the locking block moves out of the slot, it no longer clamps the positioning block, allowing the rubber disc to be pulled apart, separating the adhesive film from the button. This allows the connecting strip and rubber disc to be removed for replacement, preventing the damaged disc from being used continuously and compromising its protective effect on the button. This method also allows for quick disassembly and replacement of the rubber disc, simplifying the process and improving replacement efficiency. Furthermore, this method allows for replacement of a single rubber disc without disassembling the entire frame, thus saving replacement costs. Attached Figure Description

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0034] The embodiments of this utility model will be described below based on its overall structure.

[0035] Example 1:

[0036] A voltage-resistant electronic membrane switch, such as Figures 1-6 As shown, the device includes a membrane switch body 1. A plastic frame 3 is bonded to the outer surface of the membrane switch body 1. A horizontal bar 4 is installed inside the plastic frame 3, and multiple connecting strips 5 are detachably connected between the horizontal bar 4 and the inner wall of the plastic frame 3. A disassembly assembly 8 is provided on the plastic frame 3 and the horizontal bar 4. A plastic tray 6 is connected between every two connecting strips 5, and an adhesive patch 7 is provided on the back of the plastic tray 6. The horizontal bar 4 is bonded to the membrane switch body 1, and the plastic tray 6 can protect the button 2. Multiple buttons 2 are also installed on the outer surface of the membrane switch body 1. Button 2 corresponds one-to-one with the rubber plate 6. The adhesive patch 7 is bonded to button 2. When a person presses the rubber plate 6, the soft contact surface under the rubber plate 6, together with the soft adhesive patch 7, presses the button 2, thereby preventing the button 2 from being damaged by pressure and friction from external objects, and improving the pressure resistance life of button 2 on the surface of the membrane switch. The top of the membrane switch body 1 is connected to a DuPont wire 9, and the top of the DuPont wire 9 is connected to a plug 10. The combination of DuPont wire 9 and plug 10 enables the membrane switch to be connected to an external circuit.

[0037] See Figures 1-6The disassembly and assembly component 8 includes multiple positioning grooves 804 on the outer surface of the horizontal bar 4 and the outer surface of the rubber frame 3, multiple sliding grooves 801 on the bottom and top of the horizontal bar 4 and the upper and lower interior of the rubber frame 3, and positioning blocks 803 installed on the connecting bar 5. A spring 802 is installed inside the sliding groove 801, and one end of the spring 802 is connected to a movable block 807. A slot 806 is provided on one side of the positioning block 803, and a locking block 805 extending into the slot 806 is installed on one side of the movable block 807. When the locking block 805 is removed from the slot 806, it no longer locks and limits the positioning block 803, so that the connecting bar 5 and the rubber disc 6 can be removed for replacement of the damaged rubber disc 6.

[0038] Specifically, the rubber tray 6 and the connecting strip 5 are detachably connected to the rubber frame 3 via the positioning block 803, which facilitates the disassembly and replacement of the rubber tray 6 and the connecting strip 5. The positioning block 803 is adapted to the positioning groove 804. When the positioning block 803 is inserted into the positioning groove 804, the connecting strip 5 and the rubber tray 6 can be positioned. The locking block 805 is adapted to the locking groove 806. The locking block 805 is slidably connected to the sliding groove 801 via the movable block 807. When the locking block 805 is locked into the locking groove 806, the positioning block 803 can be locked and limited to prevent the positioning block 803 from falling out of the positioning groove 804.

[0039] Example 2:

[0040] Based on the above embodiment one, in order to facilitate the movement of the card block 805 by the staff so that the card block 805 can be moved out of the card slot 806, the following structure will be set.

[0041] See Figures 2-6 A pusher 808 is installed on one side of the movable block 807 that extends to the outside of the slide groove 801, so that the operator can push the movable block 807 to move, so that the movable block 807 can drive the locking block 805 to move, and the locking block 805 can be removed from the locking groove 806, thereby releasing the limit on the positioning block 803.

[0042] The working principle of this utility model is as follows: First, after the glue frame 3 and the horizontal bar 4 are glued to the surface of the membrane switch body 1, the glue tray 6 between the connecting strips 5 is pressed on the top of the button 2. At this time, the adhesive patch 7 at the groove below the glue tray 6 is glued to the surface of the button 2. At this time, the glue frame 3, the horizontal bar 4 and the glue tray 6 are fixed on the surface of the membrane switch body 1 and the button 2. When a person presses the glue tray 6, the soft contact surface below the glue tray 6, together with the soft adhesive patch 7, presses the button 2, thereby avoiding the button 2 from being damaged by external pressure and friction, and improving the pressure resistance life of the button 2 on the surface of the membrane switch body 1.

[0043] When the rubber disc 6 is damaged due to prolonged pressure, it needs to be disassembled and replaced. At this time, the operator pushes the locking block 805 with the pusher block 808. After the locking block 805 moves out of the slot 806, it no longer locks and limits the positioning block 803. Then the rubber disc 6 is pulled, causing the adhesive patch 7 to separate from the button 2. In this way, the connecting strip 5 and the rubber disc 6 can be removed so that the damaged rubber disc 6 can be replaced, avoiding the continued use of the damaged rubber disc 6 and affecting the protective effect on the button 2.
