The utility model discloses a silica gel button has adopted dropout prevention means, simple structure, and reasonable in design through the structure of falling the boss on the dropout prevention means, with silica gel button left-hand thread in the mounting groove on the silica gel base plate to avoid the silica gel button to drop, reduce the secondary assembly.
Description
Technical Field
The utility model belongs to a button, concretely relates to silica gel button with dropout prevention means.
Background
The press of many electronic product buttons realizes through the light touch switch on the PCBA when switching on at present, and PCBA's protection requirement grade is higher, can satisfy this requirement through the structural style that the compressed silica gel pad formed the inside sealed cavity of remote control key. Therefore, the silicon rubber pad structure is widely applied to the key design of electronic products, and meanwhile, in order to improve the pressing comfort level, the key design of most electronic products can be matched with plastic keys on the basis of the silicon rubber pad structure.
In the prior art, the silica gel pad structure comprises a silica gel pad and a silica gel key arranged on the silica gel pad, the front surface of the silica gel key is arranged opposite to the back surface of the plastic key, the back surface of the silica gel key is arranged opposite to the tact switch on the PCBA, and when a user presses the front surface of the plastic key, the pressing force is applied to the tact switch through the silica gel key contacted with the plastic key, so that the tact switch is switched on.
However, when the number of times of pressing the key increases, the key is easy to fall off, so that secondary assembly is caused, and the production efficiency is affected.
Disclosure of Invention
The to-be-solved technical problem of the utility model is to provide a silica gel button with dropout prevention means, simple structure, reasonable in design has effectively reduced when pressing down the number of times and increasing, the phenomenon that the button drops.
In order to solve the technical problem, the utility model discloses take following technical scheme: the utility model discloses a silica gel button with dropout prevention means, its innovation point lies in: the key groove is arranged on the front surface of the silica gel substrate, and the silica gel key is arranged in the key groove; a mounting groove for mounting the silica gel key is formed in the back side of the silica gel substrate corresponding to the silica gel key, and conductive contacts are arranged at four corners of the mounting groove; the mounting groove is provided with an anti-drop device, the anti-drop device is a cylindrical geometric body, and the middle part of the anti-drop device is of an inverted boss structure.
Preferably, four corners of the reverse side of the silica gel substrate are provided with fixing columns and positioning holes, and the fixing columns and the positioning holes are arranged on the same connecting edge in a staggered mode.
Preferably, the top of the anti-falling device penetrates through the installation groove to be connected with the silica gel key, and the upper end of the inverted boss structure is fixed inside the installation groove.
Preferably, the diameter of the inverted boss structure is larger than the diameters of the top and the bottom of the anti-falling device.
Preferably, an arc surface for transition is further arranged between the inverted boss structure and the top of the anti-falling device.
The utility model has the advantages that: the utility model discloses a silica gel button has adopted dropout prevention means, simple structure, and reasonable in design through the structure of falling the boss on the dropout prevention means, with silica gel button left-hand thread in the mounting groove on the silica gel base plate to avoid the silica gel button to drop, reduce the secondary assembly.

Detailed Description
The technical solution of the present invention will be described clearly and completely through the following detailed description.
The utility model relates to a silica gel key with an anti-drop device, which is mainly composed of a silica gel key 2 arranged on a silica gel substrate 1, the concrete structure is shown in figure 1, and two side edges of the silica gel substrate 1 are provided with symmetrical installation positioning grooves 3 for convenient installation and positioning; the front surface of the silica gel substrate 1 is provided with a key slot 4, and the silica gel key 2 is arranged in the key slot 4.
As shown in fig. 2, a mounting groove 5 is formed on the back surface of the silica gel substrate 1 corresponding to the silica gel key 2 for mounting the silica gel key 2; for convenience of installation, four corners of the reverse side of the silica gel substrate 1 are provided with fixing columns 6 and positioning holes 7, and the fixing columns 6 and the positioning holes 7 are arranged on the same connecting edge in a staggered manner; conductive contacts 8 are provided at four corners of the mounting groove 5.
The utility model discloses still be equipped with dropout prevention means 9 on mounting groove 5, as shown in fig. 2, fig. 3, dropout prevention means 9 is a column geometry, and its middle part is for falling lug boss structure 10. The diameter of the inverted boss structure 10 is larger than the diameters of the top and the bottom of the anti-falling device 9. An arc surface 11 for transition is further arranged between the inverted boss structure 10 and the top of the anti-falling device 9. The utility model discloses well anti-drop device 9's top is passed mounting groove 5 and is connected with silica gel button 2, and falls the upper end of boss structure 10 and fix inside mounting groove 5.
