Description

Technical Field

[0001] The utility model relates to the technical field of card holders for card reading devices, in particular to an anti-static side ESD card holder. Background Art

[0002] An IC card, short for Integrated Circuit Card, consists of an integrated circuit chip embedded in a plastic card. An IC card is about the same size as a magnetic card. The chip typically consists of non-volatile memory (ROM, EPROM, E2PROM), protection logic circuits, and even a CPU (central processing unit), leading to its use as a microcircuit card.

[0003] The communication method between the IC card and the reader / writer can be contact or contactless. Based on the communication interface, IC cards are divided into contact IC cards, contactless IC cards, and dual-interface cards (with both contact and contactless communication interfaces). The so-called contact IC card is an IC card that uses physical electrical contacts to connect the integrated circuit inside the card to the external interface device.

[0004] In daily life, when using IC cards, the IC card is inserted into the corresponding IC card holder and contacts the electrostatic conduction mechanism on the card holder to dissipate the accumulated electrostatic charge, thereby preventing static electricity from damaging the electronic components on the device motherboard and related circuit boards.

[0005] However, some metal IC cards currently on the market have printed coatings on the front or back, which causes the ESD structure of the IC card holder to be unable to effectively contact the metal IC card, resulting in a reduced ESD effect and even inability to conduct static electricity. Utility Model Content

[0006] (1) Technical problems solved

[0007] In response to the shortcomings of the existing technology, the utility model provides an anti-static side ESD card socket, which solves the problem that the ESD structure of the IC card socket cannot effectively contact the metal IC card due to the printed coating on the front or back of the metal IC card, resulting in a reduced ESD effect or even the inability to conduct static electricity.

[0008] (2) Technical solution

[0009] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0010] An anti-static side ESD card socket includes a card socket body and ESD terminals. The grooves arranged on both sides of the card socket body are matched with the locking parts arranged at the corresponding positions on both sides of the cover plate. The gap formed by the front end of the cover plate and the card socket body is used to insert the IC card, and the ESD terminals are placed in the installation grooves arranged on both sides of the front end of the card socket body. The card socket body is also provided with a conductive terminal that contacts the IC card.

[0011] Furthermore, the card base body is a plastic part, the material of which is LCP, and a sealing tape is attached to the card base body, the material of which is PET;

[0012] The rear end of the card holder body is also provided with eight connecting terminals;

[0013] A switch component is also arranged in the card seat body, and the switch component includes an enclosed switch and a switch spring. The enclosed switch is located above the switch spring.

[0014] Furthermore, the ESD terminal is a straight bar terminal, and the plug-in socket integrally formed on the straight bar terminal is inserted into the slot at the corresponding position of the mounting slot on the card holder body, and the arc-shaped bending resistance portion integrally formed at one end of the straight bar terminal extends from the mounting slot to the two ends of the gap for inserting the IC card, and resists the side of the IC card.

[0015] Furthermore, the ESD terminal is a snap-on terminal, and the lower snap-on plate and the upper snap-on plate integrally formed on the snap-on terminal are snapped into the slots at the corresponding positions of the mounting slots on the card holder body. The arc-shaped curved contact strip integrally formed at one end of the snap-on terminal extends from the mounting slot to the two ends of the gap for inserting the IC card, and abuts against the side of the IC card.

[0016] (3) Beneficial effects

[0017] Compared with the existing technology, this utility model provides an anti-static side ESD card holder with the following features:

[0018] Beneficial effects:

[0019] The utility model arranges ESD terminals at both ends of the IC card insertion gap on the card holder. When the IC card is inserted, the ESD terminals first contact the ESD terminals, which quickly conduct away the static electricity on the card body. The static electricity can be smoothly conducted away without inserting the IC card inside, effectively avoiding the interference of static electricity on the card holder and supporting equipment, and ensuring stable use.
