Abstract
Description
Technical Field
[0001] The present application relates to the technical field of IC card socket structure design, and in particular to an IC card socket. Background Art
[0002] The IC card holders commonly used in the market are designed to ensure stable insertion and reading of IC cards. However, during long-term use, foreign objects such as dust and paper scraps are easily accumulated at the tail end of these card holders. These foreign objects gradually accumulate and agglomerate, hindering the normal insertion of IC cards, thereby affecting the function and service life of the card holders.
[0003] In the prior art, in order to solve the problem of foreign matter accumulation in the IC card holder, the card holder is usually disassembled frequently and regularly to remove the foreign matter, or a new card holder is directly replaced. These methods are not only cumbersome to operate, but also increase the cost of maintenance and replacement.
[0004] Therefore, based on the above problems, the prior art needs to be improved. Utility Model Content
[0005] The purpose of this application is to effectively extend the service life of the card holder and reduce maintenance costs.
[0006] The above technical purpose of the present application is achieved through the following technical scheme: an IC card socket, comprising a base, a cover body is provided on the base, the base and the cover body together form a slot for accommodating an inserted IC card, and a plurality of terminals are provided on the base; a limit block is provided at the bottom of the slot, the limit block is arranged on the base or the cover body, and through the limit block, a storage gap is formed between the IC card inserted into the slot and the bottom of the slot.
[0007] By adopting the above technical solution, by setting a limit stopper at the bottom of the slot, the IC card will not be inserted too deep during the insertion process, ensuring that the card stays stably at the predetermined position, avoiding poor contact or damage to the card caused by too deep insertion. The storage gap is set at the tail end of the card holder to form a space. When foreign objects such as dust and paper scraps accumulate and agglomerate during long-term use, foreign objects are accumulated through the storage gap to avoid foreign objects hindering the normal insertion of the IC card, thereby affecting the function and service life of the card holder. The design of the limit stopper ensures that the IC card can be accurately positioned in the slot, thereby ensuring a reliable connection between the card and the terminal, and avoiding physical damage to the card that may be caused by excessive insertion. The storage gap provides a certain buffer space for the card, reducing the pressure and friction on the card in the slot. Even if there are tiny foreign objects, the storage gap can effectively isolate these foreign objects to prevent them from affecting the contact performance, thereby improving the stability and reliability of signal transmission.
[0008] Optionally, a mounting groove is recessed in the base, a hollow bottom of the mounting groove is formed with an escape opening, a switch is provided at the escape opening, a spring sheet is installed in the mounting groove, one end of the spring sheet away from the switch is fixed to the mounting groove wall, and one end of the spring sheet close to the switch abuts against or separates from the switch.
[0009] By adopting the above technical solution, the avoidance formed in the recessed installation groove in the base, combined with the spring and switch structure installed in the groove, can automatically trigger the switch when the IC card is inserted. Due to the automatic detection function, the user does not need to manually confirm whether the card is inserted properly, and the operation is simpler. The instant feedback when inserting the card (such as the device prompt sound or indicator light) also improves the user experience and increases the convenience and reliability of use.
[0010] Optionally, there are a plurality of limit stops.
[0011] By adopting the above technical solution, the setting of multiple limit blocks ensures that the IC card remains horizontal when inserted and does not tilt, thereby ensuring uniform contact between the card and the terminal, reducing data transmission problems caused by poor contact, and improving the stability and reliability of signal transmission. The design of multiple limit blocks disperses the pressure when the card is inserted, avoids wear or damage caused by excessive pressure on a single position, and extends the service life of the IC card and the IC card holder.
[0012] Optionally, the width of the storage gap is 0.1 mm to 10 mm.
[0013] By adopting the above technical solution and adjusting the width of the storage gap according to actual conditions, it can better accommodate various foreign objects around the card holder that may enter the slot, including dust, paper scraps, etc., which helps to minimize the impact of foreign object accumulation on the normal operation of the IC card holder and IC card, and improves the reliability and flexibility of the IC card holder.
[0014] Optionally, the base is hollow and has an embedding groove, and a grounding plate is provided in the embedding groove.
[0015] By adopting the above technical solution, the grounding plate is stably installed through the mounting groove, and the grounding plate is electrically connected to the PCB board. The setting of the grounding plate can effectively provide electromagnetic shielding protection and reduce the impact of external electromagnetic interference on the internal circuit of the IC card holder and the IC card. By connecting to the ground wire, the grounding plate can guide external electromagnetic waves into the ground, thereby protecting the signal transmission inside the IC card holder from interference and improving the stability and reliability of the system.
[0016] Optionally, the base and the cover are detachably connected, a first clamping piece is provided on the base, a second clamping piece is provided on the cover, and the first clamping piece and the second clamping piece are engaged with each other.
[0017] By adopting the above technical solution, the detachable connection design of the base and the cover makes maintenance and replacement more convenient. When the inside of the base needs to be repaired or replaced, only the cover needs to be removed without removing the entire IC card holder, saving time and cost for maintenance and replacement. After removing the base and the cover, the inside of the IC card holder can be cleaned more easily. This helps to keep the IC card holder clean, reduces the impact of foreign matter accumulation on the normal operation of the equipment, and extends the service life of the IC card holder.
[0018] In summary, this application has at least the following beneficial effects:
[0019] 1. By setting a limit stopper at the bottom of the slot, the IC card will not be inserted too deep during the insertion process, ensuring that the card stays stably in the predetermined position, avoiding poor contact or damage to the card caused by too deep insertion. The storage gap is set to form a space at the tail end of the card holder. When foreign objects such as dust and paper scraps accumulate and clump during long-term use, foreign objects accumulate through the storage gap to prevent foreign objects from obstructing the normal insertion of the IC card, thereby affecting the function and service life of the card holder. The design of the limit stopper ensures that the IC card can be accurately positioned in the slot, thereby ensuring a reliable connection between the card and the terminal, and avoiding physical damage to the card that may be caused by excessive insertion. The storage gap provides a certain buffer space for the card, reducing the pressure and friction on the card in the slot. Even if there are tiny foreign objects, the storage gap can effectively isolate these foreign objects to prevent them from affecting the contact performance, thereby improving the stability and reliability of signal transmission.
[0020] 2. By adjusting the width of the storage gap according to actual conditions, it can better accommodate various foreign objects around the card holder that may enter the slot, including dust, paper scraps, etc., which helps to minimize the impact of foreign matter accumulation on the normal operation of the IC card holder and IC card, and improves the reliability and flexibility of the IC card holder.
[0021] 3. The detachable connection design of the base and cover makes maintenance and replacement more convenient. When the inside of the base needs to be repaired or replaced, only the cover needs to be removed without removing the entire IC card holder, saving time and cost for maintenance and replacement. After removing the base and cover, the inside of the IC card holder can be cleaned more easily. This helps keep the IC card holder clean, reduces the impact of foreign matter accumulation on the normal operation of the equipment, and extends the service life of the IC card holder.

[0027] The present application is further described in detail below in conjunction with the accompanying drawings.
[0028] In this embodiment, refer to Figure 1-3 An IC card holder includes a base 1 and a cover 2. The base 1 and the cover 2 are combined to form a slot 3 for accommodating an IC card 4, providing a stable card insertion environment and ensuring the safe insertion and use of the IC card 4. The base 1 is provided with a plurality of terminals 5, which are integrated on a PCB board and are used to connect with the IC card 4 to realize functions such as signal transmission and power supply.
[0029] A limit stopper 7 is provided at the bottom of the slot 3. There are a plurality of limit stoppers 7, which are provided on the base 1 or the cover 2. Preferably, two limit stoppers 7 are provided, and the two limit stoppers 7 are provided on the base 1 at intervals. When the IC card 4 is inserted into the slot 3 and abuts against the limit stopper 7, a storage gap 8 is formed between the bottom of the slot 3 and the IC card 4, which can ensure that the IC card 4 is inserted into the correct position. At the same time, the storage gap 8 is used to store accumulated foreign matter to prevent the accumulation of foreign matter from affecting the normal use of the IC card 4.
[0030] In this embodiment, refer to Figure 3 The base 1 is provided with a mounting groove 9 in a concave shape. The bottom of the mounting groove 9 is hollowed out to form an escape opening 10. A switch 11 is provided at the escape opening 10. The switch 11 is embedded in the escape opening 10. The switch 11 is integrated on the PCB board. A spring 12 is installed in the mounting groove 9. The spring 12 is usually made of metal or elastic plastic material and has certain flexibility and elasticity. The end of the spring 12 away from the switch 11 is fixed to the wall of the mounting groove 9, and the end of the spring 12 close to the switch 11 can abut or separate from the switch 11. When the IC card 4 is inserted into the slot 3, the IC card 4 abuts against the spring 12 so that the spring 12 abuts against the switch 11, and the switch 11 is controlled to be turned on; when the IC card 4 is pulled out of the separation slot 3, the spring 12 rebounds away from the switch 11, and the switch 11 is controlled to be closed.

By adjusting the width of the storage gap 8 according to the actual situation, it can better accommodate various foreign objects around the card holder that may enter the slot 3, including dust, paper scraps, etc., which helps to minimize the impact of foreign object accumulation on the normal operation of the IC card holder and the IC card 4, and improves the reliability and flexibility of the IC card holder. Preferably, the width of the storage gap 8 is 1.5 mm, that is, the straight-line distance between the end of the limit stopper 7 away from the bottom of the slot 3 and the bottom of the slot 3 is 1.5 mm.
[0032] In this embodiment, refer to Figure 2-3 The base 1 is hollow with an embedding groove 13, and a grounding plate 14 is arranged in the embedding groove 13. The grounding plate 14 is integrated on the PCB board, and the grounding plate 14 is stably installed through the embedding groove 13. The grounding plate 14 is electrically connected to the PCB board. The setting of the grounding plate 14 can effectively provide electromagnetic shielding protection and reduce the influence of external electromagnetic interference on the internal circuit of the IC card holder and the IC card 4. By connecting to the ground wire, the grounding plate 14 can guide external electromagnetic waves into the ground, thereby protecting the signal transmission inside the IC card holder from interference, and improving the stability and reliability of the system.

The base 1 is provided with a first clamping member 15, and the cover 2 is provided with a second clamping member 16. Preferably, the first clamping member 15 is a card slot, and the second clamping member 16 is a buckle. The first clamping member 15 and the second clamping member 16 cooperate to clamp, so that the cover 2 is stably installed on the base 1. When the inside of the base 1 needs to be repaired or replaced, only the cover 2 needs to be removed, without removing the entire IC card holder, saving time and cost for maintenance and replacement.
