Description

Technical Field

[0001] The utility model belongs to the technical field of POS terminals, and in particular relates to a POS terminal with a silica gel key and an anti-disassembly switch based on a carbon oil structure. Background Art

[0002] The card swiping machine is referred to as POS terminal. The terminal first sends the information to the UnionPay platform by dialing the telephone line. After the UnionPay platform identifies the relevant information, it will send the deduction information to the issuing bank. After confirmation by the issuing bank, the information will be sent back to the UnionPay platform. After confirmation by UnionPay, the processed information will be sent to the front-end terminal. The terminal receives the confirmed information and then prints the receipt.

[0003] The mainstream design of the physical buttons for function settings and digital input in the current POS terminals on the market is a three-piece combination of "fixed shell + silicone buttons + pot pieces". At the same time, a carbon particle pressing process is added to the silicone buttons to achieve an anti-dismantling function. This assembly method has great limitations, and the material and assembly costs are relatively high, which is not conducive to equipment cost control. Utility Model Content

[0009] As a further description of the above technical solution:

[0010] The plurality of silica gel button main bodies, the button body, the plurality of thin walls and the plurality of anti-disassembly switch bodies are integrally formed.

[0011] As a further description of the above technical solution:

[0012] The deformation amount of the anti-disassembly switch body is 0.3-0.5mm.

[0013] As a further description of the above technical solution:

[0014] The number of the silicone key bodies is 16, and the number of the anti-disassembly switch bodies is 8.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0016] In the utility model, the anti-disassembly function is realized by brushing carbon oil on the anti-disassembly switch body of the button body to contact with the PCB body, and the key function is realized by brushing carbon oil on the silicone button body to contact with the PCB body. This design eliminates a pot piece material. After eliminating the pot piece material, the anti-disassembly and key functions are realized while reducing the material and assembly costs of the whole machine, and the feel of the key and the reliability of the whole machine can be guaranteed.
