Description

Technical Field

[0001] The utility model relates to the technical field of membrane switches, in particular to a high-viscosity and impact-resistant composite conductive functional membrane switch. Background Art

[0002] There are multiple groups of silicone buttons on the surface of the membrane switch, and a circuit board with a control system is fixed inside. The upper circuit where the silicone buttons are located contacts the lower circuit fixed on the surface of the circuit board to convey instructions. When the finger leaves the silicone button, the contact can be broken and the operation can be interrupted. The next command can only be issued after pressing it again.

[0003] Most membrane switches in the past lack a reset structure and have poor impact resistance. If the membrane switch button cannot automatically bounce back after being pressed and remains attached to the touch point of the circuit board, and if the program is still in progress and commands are issued back and forth many times, it is very easy to damage the electronic device components connected to the switch.

[0004] Now, a new type of high-viscosity and impact-resistant composite conductive functional membrane switch is proposed to solve the above problems. Utility Model Content

[0005] The utility model aims to provide a high-viscosity and impact-resistant composite conductive functional membrane switch to solve the problem of inconvenience in resetting the membrane switch mentioned in the background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-viscosity and impact-resistant composite conductive functional membrane switch, comprising a main plate and a sub-plate, the sub-plate being arranged on the right side of the main plate, the main plate and the sub-plate being longitudinally arranged with an inner cavity, the front of the main plate and the sub-plate being covered with a cover plate, and five groups of circular rings are fixed on the surface of the cover plate, silicone buttons are movably inserted in the circular rings, screw holes are arranged at the four corners of the cover plate, and screws are meshed and connected in the screw holes, five groups of pressing sheets are arranged inside the inner cavity, and touch points are installed in the pressing sheets, guide rods are fixed on both sides of the rear of the pressing sheets, ten groups of jacks are arranged at the rear of the inner cavity, and springs are fixedly connected between the two sides of the rear of the pressing sheet and the inner cavity respectively.

[0007] Preferably, the guide rod is embedded in the insertion hole, and the spring is wound around the outside of the guide rod.

[0008] Preferably, the silicone button is arranged in front of the pressing sheet, and the silicone button can swing back and forth in the ring.

[0009] Preferably, five groups of transverse grooves are arranged on the inner side behind the main plate and the auxiliary plate, a wire row is fixed at the center behind the pressing plate, and a metal plug is fixed at the port of the wire row, an open slot is arranged on the right side of the transverse groove, five groups of cylindrical chambers are arranged inside the right side of the main plate and the auxiliary plate, and a roller is movably connected to the upper part of the inner side of the cylindrical chamber.

[0010] Preferably, the center of the wire row is embedded in the bottom of the roller, and the remaining part of the wire row is wound on the surface of the roller.

[0011] Preferably, the roller can rotate in situ in the cylindrical chamber, and the right side of the cylindrical chamber is open.

[0012] Preferably, a groove is provided inside the lower part of the main plate, and a connecting key is movably connected between the front and rear parts inside the groove, an active chamber is provided inside the lower part of the sub-plate, and a connecting key is installed between the front and rear parts inside the active chamber, a positioning bolt is movably connected below the front end of the sub-plate, and a fastening bolt is movably connected below the front end of the main plate.

[0013] Preferably, the right side of the connecting key can rotate in situ in the movable chamber, and the left side of the connecting key can rotate in situ in the groove.

[0014] Compared with the prior art, the utility model has the following beneficial effects: the high-viscosity and impact-resistant composite conductive functional membrane switch not only realizes the anti-punching of the silicone button and the storage of the redundant wire row, but also realizes the adjustment of the assembly method of each button;

[0015] By installing a touch point in the pressing sheet, the cover plate with the silicone button is installed in front of the main plate or the sub-plate through screws in the screw holes at the four corners. When the silicone button is pressed, the touch point above the pressing sheet at the rear can be touched under the restriction of the ring to issue a command. After the silicone button loses the pressing force, it can be reset by its own rebound ability. When the springs on both sides of the pressing sheet are stretched, the pressing sheet adjusts its position along the guide rod embedded in the jack to avoid the touch point from contacting the silicone button again, thereby achieving the purpose of impact resistance.

[0016] Five sets of transverse grooves are arranged on the inner side of the rear of the main plate and the auxiliary plate, and five sets of cylindrical chambers are arranged on the sides of the main plate and the auxiliary plate. The winding roller can be turned through the grooves here. Because the center of the wire row is embedded in the bottom of the winding roller, the part of the wire row connected to the pressing plate remains unchanged, and the other end is wound on the surface of the winding roller. The metal plug can be pulled out at the slot, and then the length of the wire row can be adjusted to prevent the wire row from being damaged due to excessive dragging;
