Fig. 1 is a schematic structural diagram of a card reading device of an IC card according to a preferred embodiment of the present invention, and for convenience of description, only the parts related to the embodiment are shown, which are detailed as follows:

referring to fig. 1, a card reading device of an IC card provided by an embodiment of the present application includes a card slot 10, a metal card mouth 20, and a grounding device 30, where the card slot 10 is used for inserting a metal IC card 100; the metal bayonet 20 is arranged outside the bayonet 10, and the metal bayonet 20 is provided with a conductive socket 21 which penetrates through the metal bayonet 20 and is opposite to the bayonet 10; the metal bayonet 20 is electrically connected with the grounding device 30; the metal card nozzle 20 is used for acquiring electrostatic charges on the metal IC card 100 during the insertion of the metal IC card 100 into the conductive socket 21 and guiding the electrostatic charges to the ground through the grounding device 30.

It should be noted that the metal IC card 100 in the embodiment of the present application is an unconventional IC card, which supports two functions of a non-contact IC card and a contact IC card, the front and back surfaces of the card are both made of insulating materials, the interlayer of the card is made of metal, the metal is a conductor, and can have charges, the static charges accumulate on the metal, when the charges are accumulated to a certain extent, and then the card is swiped through the metal IC card 100, and the card is not in contact with a card reading device but is infinitely close, an arc discharge occurs, so that the metal card mouth 20 is arranged outside the card insertion port 10, the static charges accumulated on the metal IC card 100 are transferred to the metal card mouth 20, and are released to the ground through the grounding device 30, during this process, the static charges can be guided to be discharged according to a known discharge path, that is, the metal IC card 100-the metal card mouth 20-the grounding device 30-ground, so as to effectively prevent the static charges accumulated on the metal IC card 100 from being transferred to the card reading device, and the work abnormity or the dead damage to the card reading device caused by static electricity is discharged according to the unknown static electricity discharge path.

It can be understood that the metal card mouth 20 of the embodiment of the present application may be in a closed loop shape, and may be attached to the side of the card reading device where the card insertion slot 10 is disposed by a double-sided adhesive, such an installation method is simple and convenient, and may be rapidly modified for the existing card reading device, for example, a metal card mouth 20 is attached to the side of the card insertion slot 10 where the existing card reading device is disposed, and then the metal card mouth 20 is grounded, so that the existing card reading device which is easily affected by the electrostatic discharge may be modified into a card reading device which may guide the electrostatic discharge according to a preset path, may not cause an abnormal operation or a crash damage to the card reading device, reduces the cost of manufacturing the card reading device for preventing electrostatic discharge, and may not cause the existing card reading device to be discarded to be wasted.

Optionally, the metal card nozzle 20 according to the embodiment of the present application may also be sleeved on a side wall of the card reading device near the card insertion slot 10, so that the metal card nozzle 20 surrounds the card insertion slot 10, and thus the metal card nozzle 20 may cover a position on the card reading device, which may be in contact with or infinitely close to the metal IC card 100, so that even if the metal IC card 100 does not approach the card reading device from a direction opposite to the card insertion slot 10, electrostatic charges accumulated on the metal IC card 100 are not transferred to the card reading device, and the card reading device is protected more comprehensively. It should be noted that, due to the limitation of the installation manner of the metal bayonet 20, the through hole formed in the middle of the metal bayonet 20 can be used as the conductive insertion opening 21, and it is obvious that the size of the conductive insertion opening 21 is larger than that of the insertion opening 10; of course, the through hole formed in the middle of the metal card mouth 20 may also be set to be a step hole, the through hole with a large diameter is sleeved on the side wall of the card reading device near the card slot 10, the through hole with a small diameter is set to be the same as the card slot 10 in shape and size, and the through hole with a small diameter is connected with the card slot 10, so that the through hole with a small diameter can be used as the conductive socket 21.

Specifically, the metal card mouth 20 of the embodiment of the present application can be integrally made of a conductive metal material such as electroplated zinc alloy; of course, a plastic card mouth may also be adopted, and a zinc alloy plating layer is electroplated on the outer surface of the plastic card mouth, so that the zinc alloy plating layer on the outer surface of the plastic card mouth may also receive and discharge the electrostatic charges accumulated on the metal IC card 100, and the plastic material is used in the structures of the plastic card mouth and the zinc alloy plating layer, so as to achieve the purpose of electric conduction through the zinc alloy plating layer, reduce the usage of the zinc alloy material, and reduce the manufacturing cost of the metal card mouth 20, but it should be noted that in the practical use, the impedance of the metal card mouth 20 with such a structure is easily affected by the environment, generates large fluctuation, and affects the stability of the electrostatic discharge capacity, so the structure type of the metal card mouth 20 may be selected according to the specific use condition.

According to the card reading device of the IC card provided by the embodiment of the present application, the metal card mouth 20 is arranged outside the card insertion opening 10, and the metal card mouth 20 has the conductive insertion opening 21 facing the card insertion opening 10, so that when the metal IC card 100 is inserted into the card insertion opening 10, the metal IC card 100 passes through the conductive insertion opening 21, the electrostatic charge on the metal IC card 100 is transferred to the metal card mouth 20, and the metal card mouth 20 is electrically connected to the grounding device 30, so that the electrostatic charge is introduced to the ground through the grounding device 30, and before the metal IC card 100 contacts the card insertion opening 10, the electrostatic charge on the metal IC card 100 is discharged through the metal card mouth 20, thereby effectively protecting the card reading device of the IC card from being influenced by static electricity to cause abnormal operation or crash.

In one embodiment, referring to fig. 1, the shape of the conductive socket 21 is the same as that of the socket 10, and the end edge of one end of the conductive socket 21 is attached to the end edge of the socket 10.

It should be noted that the shape of the conductive socket 21 can be consistent with the shape of the card slot 10, and the end edge of one end of the conductive socket 21 is attached to the end edge of the card slot 10, so that the card slot 10 is extended outward by a distance, and the metal IC card 100 can be smoothly inserted into the card slot 10 from the conductive socket 21.

Optionally, on the basis that the shape of the conductive socket 21 is the same as the shape of the card socket 10, the size of the conductive socket 21 may be larger than the size of the card socket 10, that is, the card socket 10 is located in the orthographic projection of the conductive socket 21 on the card reading device, so as to ensure that the metal IC card 100 can be smoothly inserted into the card socket 10 from the conductive socket 21.

In one embodiment, referring to fig. 1-2, the metal card tip 20 is electrically connected to the grounding device 30 through a flexible circuit board 40.

Specifically, the Flexible Printed Circuit board 40 (FPC), also called Flexible Circuit board or Flexible Circuit board, is a Flexible Printed Circuit board made of polyimide or polyester film as a base material, which has high reliability and is excellent. The high-density light-weight LED lamp has the characteristics of high wiring density, light weight, thin thickness and good bending property.

It should be noted that, since the metal card mouth 20 is located outside the card inserting port 10, the connection path between the metal card mouth 20 and the grounding device 30 may be located on the outer side surface of the card reading device, and therefore, the flexible circuit board 40 is used as the conductive connecting member between the metal card mouth 20 and the grounding device 30, which not only has a conductive function, but also has certain rigidity and flexibility, and is suitable for various connection environments existing between the metal card mouth 20 and the grounding device 30, and after the metal card mouth 20 and the grounding device 30 are connected together, even if exposed outside the card reading device, the metal IC card 100, the metal card mouth 20, the grounding device 30, and the ground static discharge path will not be damaged easily.

In one embodiment, referring to fig. 3-4, the flexible circuit board 40 is attached to the metal card mouth 20 and the grounding device 30 by conductive adhesive at two ends.

Specifically, the conductive adhesive is an adhesive having a certain conductivity after being cured or dried. It can connect multiple conductive materials together to form an electrical path between the connected materials. The conductive adhesive has the conductive principle that conductive particles are mutually contacted to form a conductive path, so that the conductive adhesive has conductivity, and the stable contact among the particles in an adhesive layer is caused by the solidification or drying of the conductive adhesive. Before the conductive adhesive is cured or dried, the conductive particles are separated in the adhesive and are not in continuous contact with each other, so that the conductive adhesive is in an insulating state. After the conductive paste is cured or dried, the volume of the adhesive shrinks due to the volatilization of the solvent and the curing of the adhesive, so that the conductive particles are in a stable continuous state with each other, thereby exhibiting conductivity.

It should be noted that, the step of electrically connecting the metal card mouth 20 and the grounding device 30 can be simplified by attaching the flexible circuit board 40 to the metal card mouth 20 and the grounding device 30 through the conductive adhesive, and since the grounding device 30 is not limited to one, the flexible circuit board 40 is electrically connected to the grounding device 30 through the conductive adhesive, so that the flexible circuit board 40 can be disconnected from the currently connected grounding device 30 and disconnected from another grounding device 30. In addition, the grounding device 30 of the embodiment of the present application is the grounding device 30 of the card reading device itself, so that the flexible circuit board 40 is connected to the grounding device 30 through a conductive adhesive, and the metal card tip 20 can also be fixed outside the card slot 10 through a double-sided adhesive, so that the metal card tip 20 can be conveniently disposed on the card reading device, so that static electricity on the metal IC card 100 is discharged according to a preset path, and the electrical performance of the grounding device 30 is not damaged by directly attaching the conductive adhesive.

It can be understood that, since at least the outer surface of the metal card mouth 20 is made of conductive metal, the flexible circuit board 40 can be adhered to any position of the metal card mouth 20 to achieve electrical connection with the metal card mouth 20, but preferably, the flexible circuit board 40 can be adhered to the surface of the metal card mouth 20 close to the card insertion opening 10, and since the surface of the metal card mouth 20 close to the card insertion opening 10 is adhered to the side surface of the card reading device where the card insertion opening 10 is arranged, the flexible circuit board 40 is clamped between the metal card mouth 20 and the side surface of the card reading device where the card insertion opening 10 is arranged, so that the connection tightness between the flexible circuit board 40 and the metal card mouth 20 is further enhanced. The flexible circuit board 40 is electrically connected to the grounding device 30, specifically, the flexible circuit board 40 is adhered to the metal of the grounding device 30 by conductive adhesive, so that the flexible circuit board 40 is electrically connected to the grounding device 30.

In one embodiment, referring to fig. 1-2 and 4, the flexible circuit board 40 is provided with an avoiding hole 41, and the avoiding hole 41 is used for preventing components on a path where the flexible circuit board 40 is disposed from being covered by the flexible circuit board 40.

Specifically, when the metal card mouth 20 in the embodiment of the present application is additionally installed on the existing card reading device, the flexible circuit board 40 connected between the metal card mouth 20 and the grounding device 30 may be located on the outer side surface of the existing card reading device, so that the existing card reading device may further be provided with a sound generating device such as a speaker, and therefore, the outer side surface of the existing card reading device may be provided with a sound generating hole, the flexible circuit board 40 may cover the sound generating hole to affect the sound generating effect, and the flexible circuit board 40 is provided with the avoiding hole 41, which may prevent the sound generating hole from being covered by the flexible circuit board 40, and may not adversely affect the sound generating effect.

In one embodiment, the grounding device 30 is optionally a SIM card socket.

It should be noted that, the grounding device 30 in the present application is a card reading device itself, and in the actual connection process between the metal card nozzle 20 and the grounding device 30, one grounding device 30 that is convenient to connect can be selected according to the structure of the card reading device, most of the existing card reading devices are mobile phones, and have one or more SIM card holders in the battery cover, the SIM card holders are metal, and the card holders are all grounded, so that the metal card nozzle 20 and the SIM card holder in the embodiment of the present application can be electrically connected together. If the card reading device does not have a SIM card socket, other grounded grounding devices 30 may be found inside the card reading device, or the grounding device 30 of the card reading device may be led out inside the card reading device through other forms such as a conductive foam or a connector.

It can be understood that when the metal card nozzle 20 is electrically connected to the SIM card socket, the flexible circuit board 40 is further provided with an avoiding hole 41 matched with the SIM card, so that the normal assembly of the SIM card on the SIM card socket is not affected.

Optionally, after the metal card mouth 20 is arranged outside the card inserting port 10 in the embodiment of the present application, the conductive inserting port 21 on the metal card mouth 20 is equivalent to a new card inserting port of a card reading device, so that a dustproof component may be arranged at one end of the conductive inserting port 21 away from the card inserting port 10, and the dustproof component may be a dustproof strip or a metal dustproof door, and is used to prevent external dust from entering into a hollow cavity of the card reading device, so as to cause contamination of the hollow cavity.

For example, when the metal card mouth 20 is not disposed outside the card insertion opening 10, that is, when a preset electrostatic discharge path is not disposed to guide the discharge of the electrostatic charges accumulated on the metal IC card 100, when the simulated human body is charged with static electricity, the two-in-one metal IC card 100 is used to brush an IC card on a card reading device, 4KV static electricity may cause the card reading device to work abnormally; when the metal card mouth 20 is disposed outside the card insertion opening 10 and the metal card mouth 20 is electrically connected to the grounding device 30, a preset electrostatic discharge path is set to guide the electrostatic charges accumulated on the metal IC card 100 to discharge, and under the same experiment condition, the card reading device still works normally under 8KV electrostatic charge. Therefore, the embodiment of the present application is equivalent to setting the preset electrostatic discharge path, so that when the metal IC card 100 is swiped, the electrostatic charges accumulated on the metal IC card 100 can be guided to discharge along the preset electrostatic discharge path, and the card reading device is protected from being influenced by static electricity to cause abnormal work or even crash.

The above description is only for the specific embodiments of the present application, but the scope of the present application is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present application, and shall be covered by the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
