A dustproof and waterproof deck

Abstract

The invention relates to the technical field of card holders for POS machines, and discloses a dustproof and waterproof card holder, comprising an upper cover and a lower casing, the upper cover and the lower casing are fastened and sealed, and one end thereof is an open end; the bottom surface of the lower casing It is closed and embedded with multiple terminals. The upper surface of the terminal is exposed on the upper surface of the lower case, and the other end of the terminal is exposed through the bottom of the lower case. When the card is inserted into the card holder through the open end , the chip of the card is in contact with the terminals. Compared with the prior art, the present invention arranges the terminals and switches in the upper cover and the lower housing, and provides three-side seals and one side opening, which can prevent dust and prevent water from penetrating into the card holder. Extend the service life of the POS machine.

Description

technical field [0001] The invention relates to the technical field of POS card holders, in particular to a dustproof and waterproof card holder. Background technique [0002] At present, with the rapid development of electronic technology, the application of POS machines is extremely wide, and POS machines are required to swipe cards in charge control fields such as stores. The POS machines read the information of the cardholder on the bank card through the card reader. The POS operator enters the transaction amount, the cardholder enters the personal identification information, and the POS machine uploads the above information to the card-issuing bank system through the UnionPay center to complete the online transaction. [0003] On a traditional POS machine, the IC card holder is patched on the PCB, the solder pins are exposed on the periphery and the card slot is connected to the socket hole and wiring at the bottom, and water will flow into the bottom of the POS machine...

AI Technical Summary

Problems solved by technology

[0003] On a traditional POS machine, the IC card holder is patched on the PCB, the solder pins are exposed on the periphery and the card slot is connected to the socket hole and wiring at the bottom, and water will flow into the bottom of the POS machine through the gap. When it is in the water, it is easy to break the POS machine, and the welding feet are exposed outside. After a long time of use, a large amount of dust will be generated, which will greatly reduce the use effect of the card and greatly affect people's lives.

[0004] Moreover, the friction force between the card holder terminal structure and the card of the traditional POS machine is relatively large, and the metal chip on the card is easy to be damaged after long-term use, and it is not smooth when inserting the card, making it difficult to insert the card.
