Description

Technical Field

[0001] This utility model relates to the field of membrane switch technology, specifically a display membrane switch. Background Technology

[0002] A membrane switch is an operating system that integrates button functions, indicator elements, and an instrument panel. It consists of four parts: a panel, an upper circuit, an isolation layer, and a lower circuit. When the membrane switch is pressed, the contacts of the upper circuit deform downwards and make contact with the plates of the lower circuit to conduct electricity. When the finger is released, the contacts of the upper circuit bounce back, the circuit is broken, and the circuit triggers a signal. It is widely used in electronic communication, electronic measurement instruments, industrial control, medical equipment, automotive industry, smart toys, home appliances and other fields.

[0003] Currently, some membrane switches are connected via adhesive on the back and mating parts. The adhesive on the back of the membrane switch is protected by release paper. During bonding, the workers need to peel off the release paper. However, because the membrane switch material is relatively soft and contains LED lights and electronic components, peeling off the release paper can easily cause the membrane switch to bend, thereby damaging the membrane switch. Summary of the Invention

[0004] The purpose of this invention is to provide a display membrane switch to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a display membrane switch, comprising a display membrane switch body, a connector body for connecting to a screen being connected to one side of the surface of the display membrane switch body, release paper for protection being adhered to the surface of the display membrane switch body, a peeling head being fixed to one side of the surface of the release paper, a protective plate being provided on the surface of the display membrane switch body, a protective cover being provided on the surface of the protective plate, and a plurality of connecting feet being provided on the surface of the protective plate.

[0006] Preferably, the connecting leg is L-shaped and designed to be easily broken.

[0007] Preferably, the material of the peeling head is the same as that of the release paper, and it is semi-circular in shape.

[0008] Preferably, the surface of the protective cover is provided with a sealing strip, and the surface of the sealing strip is provided with a felt strip.

[0009] Preferably, the shape of the protective cover is complementary to the shape of the connector head.

[0010] Preferably, the protective plate is made of acrylic sheet and is transparent.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] When the display membrane switch body needs to be installed, the operator can use a peeling head to remove the release paper from the display membrane switch body. When the release paper is removed, the display membrane switch body is protected from bending under the protection of the protective plate, thus protecting the installation of the display membrane switch body. In addition, the protective plate can protect the display membrane switch body during transportation, preventing damage caused by friction or bending during daily transportation.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4As shown, a display membrane switch includes a display membrane switch body 1, a connector body 2 for connecting to a screen connected to one side of the surface of the display membrane switch body 1, release paper 3 for protection adhered to the surface of the display membrane switch body 1, a peeling head 4 fixed to one side of the surface of the release paper 3, a protective plate 5 provided on the surface of the display membrane switch body 1, a protective cover 7 provided on the surface of the protective plate 5, and a plurality of connecting feet 6 provided on the surface of the protective plate 5. When the display membrane switch body 1 needs to be installed, the operator can use the peeling head 4 to detach the release paper 3 from the display membrane switch body 1. When the release paper 3 is detached, the display membrane switch body 1 is prevented from bending under the protection of the protective plate 5, thus protecting the installation of the display membrane switch body 1. In addition, under the action of the protective plate 5, the display membrane switch body 1 can be protected during transportation, preventing damage caused by friction or bending during daily transportation.

[0020] The connecting pin 6 is L-shaped and designed to be easily broken. In this embodiment, this design improves the connection between the connecting pin 6 and the display membrane switch body 1, and facilitates the disconnection of the connecting pin 6 after the release paper 3 is peeled off.

[0021] The material of the peeling head 4 is the same as that of the release paper 3, and it is semi-circular. In this embodiment, this design allows the worker to apply force to the release paper 3 when the worker needs to remove it.

[0022] The protective cover 7 is provided with a sealing strip 8, and the surface of the sealing strip 8 is provided with a wool strip. In this embodiment, by setting the sealing strip 8, when the connector body 2 is placed inside the protective cover 7, the sealing strip 8 can be used to clamp and restrict the connector body 2, providing a damping feel, and the wool strip can be used to prevent dust.

[0023] The shape of the protective cover 7 is complementary to the shape of the head of the connector body 2. In this embodiment, this arrangement facilitates the connection between the connector body 2 and the protective cover 7, and improves the connection stability between the connector body 2 and the protective cover 7.

[0024] The protective plate 5 is made of acrylic sheet and is transparent. In this embodiment, this design improves the durability and anti-slip properties of the protective plate 5, and provides a certain degree of protection. Furthermore, the transparent material allows staff to directly observe the display membrane switch body 1.

[0025] Working principle: When the display membrane switch body 1 is installed by mating with the display membrane through the connector body 2, the operator first places the display membrane switch body 1 at the mating point and cleans the mating point with alcohol to remove oil and dust. Then, using the peeling head 4, the release paper 3 is peeled off. During the peeling process, the protective plate 5 protects the display membrane switch body 1, preventing it from bending and protecting the internal electronic components. After the release paper 3 is completely peeled off, the connecting pin 6 is exposed, and the operator can then break off the connecting pin 6 to remove the protective plate 5. During this process, the operator can also remove the connector body 2. After completing the above steps, the operator can then connect the display membrane switch body 1 to the mating point using the adhesive on the back.
