[0002] The membrane switch is an operating system that integrates key functions, indicating elements, and instrument panels. It consists of four parts: panel, upper circuit, isolation layer, and lower circuit. During use, when the user applies a certain force to bring the upper and lower layers of the film close to each other, the conductors of the upper and lower layers of the film will contact each other and become electrically conductive, making it convenient for personnel to operate it.

DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0031] In order to facilitate the use of the limit card slot to connect and complete the assembly operation of the membrane switch, the structure is simple and easy to operate, and the use is more convenient and quick, which greatly improves the convenience of installation and improves the quality of use. Figure 1-3 As shown, the utility model discloses a conveniently installed membrane switch, comprising a housing 1, a membrane switch 2 and a positioning assembly 5. The membrane switch 2 is arranged in the housing 1. The housing 1 comprises a bottom plate 3 and a top cover 4. A positioning assembly 5 is arranged on one side of the housing 1.

[0032] A placement groove 301 is provided in the bottom plate 3, and a clamping strip 401 is connected to the bottom of the top cover 4 by screws. A sliding groove 402 is provided on the inner side of the clamping strip 401, and a positioning rod 403 is slidably connected in the sliding groove 402. A spring 404 is installed in the sliding groove 402 on the inner side of the positioning rod 403 through the clamping groove.

[0033] When in use, the membrane switch 2 can be limited by sliding the card strip 401 and the top cover 4, which improves the accuracy of its installation operation and makes it less likely to deviate, thereby improving the convenience and stability of the installation of the membrane switch 2. The spring 404 force is used to push the positioning rod 403 to slide, so that the limit fixation can be quickly completed. The structure is simple and easy to operate, and the use is more convenient and reliable.

[0034] In order to improve the use quality of the membrane switch, for example, Figure 4 As shown, the utility model also includes that the positioning assembly 5 includes a fixed block 501, and the bottom plate 3 is fixedly connected to the fixed block 501 by screws, a corresponding connecting block 502 is arranged on the top of the fixed block 501, and the top cover 4 is connected to the connecting block 502 by screws, a sliding sleeve 503 is arranged on one side of the fixed block 501, and the sliding sleeve 503 and the fixed block 501 are both provided with openings 505, and a sponge pad 504 is connected to the top and bottom of the opening 505 in the sliding sleeve 503 by gluing.

[0035] When in use, the sliding of the sleeve 503 can utilize the friction contact of the sponge pad 504 to assist in cleaning the membrane switch, thereby improving its stability in use. At the same time, the fixing hole 501, the connecting block 502 and the sleeve 503 can also improve the stability of the connection of the membrane switch 2 and reduce damage caused by bending.

[0036] For example, Figure 2 As shown, the utility model also includes that positioning holes 302 corresponding to the positioning rods 403 are opened on both sides of the placement groove 301, the bottom of the top cover 4 is located on the outside of the clamping strip 401 and is connected to the insertion strip 405 by screws, and the surface of the top of the bottom plate 3 is opened with a slot 303 corresponding to the insertion strip 405.

[0037] When in use, the stability of the assembly and disassembly operation of the housing 1 can be improved through the limiting connection between the inserting strip 405 and the slot 303 .

[0038] For example, Figure 5 As shown, the utility model also includes that the membrane switch 2 includes a DuPont line 201 .

[0039] When in use, the DuPont line 201 is used to connect the device for easy use.

[0040] For example, Figure 4 As shown, the utility model also includes that a first magnetic block 506 corresponding to the connecting block 502 is fixedly installed on the top of the fixing block 501 through a slot, and a second magnetic block 507 corresponding to the sliding sleeve 503 is arranged on the inner side of the fixing block 501 .

[0041] When in use, the first magnetic block 506 and the second magnetic block 507 can be used to quickly connect and position the fixing block 501 with the connecting block 502 and the sliding sleeve 503 by magnetism.

[0042] For example, Figure 3 As shown, the utility model also includes that moisture-proof particles 407 are arranged in the clamping strip 401, an air inlet hole 406 is opened on one side of the clamping strip 401, and the moisture-proof particles 407 are hygroscopic transparent silica gel particles.

[0043] When in use, a moisture-proof mechanism can be added to slow down the loss of the membrane switch caused by the working environment, thereby extending the stability and life of the membrane switch.

[0044] For example, Figure 1 As shown, the utility model also includes that a button 6 is provided on the surface of the top cover 4 .

[0045] When in use, the button 6 is used to press the membrane switch 2 to operate.

[0046] When the utility model is used, the operator first places the membrane switch 2 into the placement groove 301 of the bottom plate 3 during the installation process, and at the same time passes the Dupont line 201 through the fixing hole 501 and the opening 505 of the sliding sleeve 503, and then pushes the top cover 4 from the top side of the bottom plate 3, so that the insertion strip 405 is inserted into the corresponding slot 303. When the top cover 4 slides, the clamping strip 401 plays an auxiliary limiting role for the membrane switch 2, thereby improving the stability and accuracy of the installation, and it is more difficult to cause deviation. Moreover, when the top cover 4 is pushed to the specified position, under the push of the elastic force of the spring 404, the positioning rod 403 slides out of the sliding groove 402 and is clamped into the corresponding positioning hole 302 to complete the locking action. At the same time, the connecting block 502 is magnetically connected with the first magnetic block 506, thereby completing the installation operation of the shell. The structure is simple, the cost is low, and the disassembly and assembly are more convenient and reliable.

[0047] Moreover, before using the membrane switch 2, the sliding sleeve 503 can be pulled to slide back and forth, and the surface of the DuPont line 201 can be assisted to be cleaned through the sponge pad 504 in the opening 505, thereby improving the working quality of the membrane switch 2 and enhancing the stability of use.

[0048] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions in the specification are only to illustrate the principles of the utility model.
