Description

Technical Field

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

[0002] The membrane switch is an operating system that integrates key functions and instrument panels. It consists of four parts: panel, upper circuit, isolation layer, and lower circuit. By pressing the membrane switch, the contacts of the upper circuit deform downward and contact and conduct with the plates of the lower circuit. Then, when the finger is released, the contacts of the upper circuit rebound and reset, disconnecting the circuit and triggering a signal.

[0003] In the current prior art, the line outlet of the membrane switch is easily bent by pressure, resulting in line breakage and damage. Therefore, when packaging the membrane switch at the factory, the line outlet of the membrane switch needs to be clamped in the positioning groove of the protective box for protection. Although the line outlet of the membrane switch can be supported to prevent bending and damage, there is a lack of limit fixation for the membrane switch and the line outlet, which makes it easy for the membrane switch to shake in the positioning groove of the protective box during transportation. This may cause bending and damage at the connection between the membrane switch and the line outlet. In view of this, the present utility model is specially proposed. Utility Model Content

[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0021] Embodiment 1:

[0022] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A membrane switch outlet terminal protection structure includes a sealing protective member, wherein the sealing protective member includes a lower protective plate 1, an upper protective plate 102 and a groove 103 opened on the upper protective plate 102, and the lower protective plate 1 is detachably connected to the upper protective plate 102; an elastic protective member is arranged in the groove 103 and is used to provide support and protection for the membrane switch outlet terminal placed between the lower protective plate 1 and the upper protective plate 102.

[0023] The lower protective plate 1 is symmetrically fixedly connected with a plug-in block 2, and the upper protective plate 102 is penetrated by a plug-in slot 201 corresponding to the plug-in block 2; it also includes a clamping component, the plug-in block 2 is plugged into the plug-in slot 201, and is fixedly connected to the upper protective plate 102 through the clamping component.

[0024] The snap-fit ​​component includes a snap-fit ​​block 204 , a slide groove 202 is provided on the plug-in block 2 , the snap-fit ​​block 204 is slidably connected in the slide groove 202 , a spring 203 is fixedly connected between the snap-fit ​​block 204 and the inner wall of the slide groove 202 , and the snap-fit ​​block 204 is snap-fitted to the outer surface of the upper protective plate 102 .

[0025] A positioning groove 101 is formed on the lower protection plate 1 .

[0026] The elastic protective member includes an elastic protective pad 104 , and the elastic protective pad 104 is fixedly connected in the groove 103 .

[0027] When in use, the membrane switch and the outlet terminal of the membrane switch are placed in the positioning groove 101, and then the upper protective plate 102 is covered on the lower protective plate 1, so that the upper protective plate 102 forms a sealing protective member in combination with the lower protective plate 1, thereby being able to provide effective protection for the membrane switch and the outlet terminal of the membrane switch, and prevent the outlet terminal of the membrane switch from being bent and damaged during transportation. At the same time, the membrane switch is wrapped by the elastic protective member. Since the elastic protective member adopts an elastic latex pad, the latex pad has good elasticity and can fit the membrane switch well, thereby being able to play a role in firmly limiting and fixing the membrane switch, and preventing the membrane switch from shaking in the positioning groove 101, causing the outlet terminal of the membrane switch to be bent and damaged;

[0028] At the same time, when the upper protective plate 102 is covered on the lower protective plate 1, the plug-in block 2 is plugged into the plug-in slot 201. At this time, the clamping block 204 is squeezed by the upper protective plate 102 to slide into the slide slot 202 and compress the spring 203 until the clamping block 204 is completely retracted into the slide slot 202. When the upper protective plate 102 is in contact with the lower protective plate 1, the slide slot 202 on the plug-in block 2 moves out of the plug-in slot 201, and the compressed spring 203 generates a thrust, pushing the clamping block 204 to slide into the slide slot 202 and clamp on the outer surface of the upper protective plate 102, thereby firmly limiting and fixing the upper protective plate 102 and the lower protective plate 1 that are assembled together, thereby facilitating the staff to quickly assemble the upper protective plate 102 and the lower protective plate 1.

[0029] When the membrane switch and the wire outlet of the membrane switch need to be taken out from the sealing protection component, the clamping block 204 is pressed, and the clamping block 204 moves into the slide groove 202 after being pressed, and compresses the spring 203 until the clamping block 204 is completely retracted into the slide groove 202, thereby releasing the limit fixation of the upper protective plate 102 and the lower protective plate 1, and then the upper protective plate 102 covering the lower protective plate 1 is removed, and then the staff can take the membrane switch and the wire outlet of the membrane switch out from the sealing protection component.

[0030] Embodiment 2:

[0031] Reference Figure 1 , Figure 4 A membrane switch outlet terminal protection structure is basically the same as that of Example 1, and further, a plurality of positioning grooves 101 are evenly spaced; through the plurality of positioning grooves 101 evenly spaced on the lower protective plate 1, a plurality of membrane switches together with the outlet terminals of the membrane switches can be preliminarily positioned.

[0032] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention.
