Definitions
- the present invention relates to an Ic force for sealing and incorporating an integrated circuit board.
- a card using a magnetic drive as a memory medium is used as a magnetic card, and a card for an online system such as a bank is used as a card. It is widely used for credit cards.
- This type of IC card has a processor and memory internally composed of a CM0S type integrated circuit, and its external shape is shown in Fig. 3. As shown in the perspective view, it is formed as a card-shaped plastic case a made of plastic material, and the upper and lower surfaces are covered with a reinforcing metal plate b. ing . A connector c is provided on the end face of the card-like case to connect to related devices when writing data to the IC card or reading data. It has been broken.
- the metal plate that protects the formed IC card and the body of the IC card is reinforced to prevent its deformation and breakage. Since the connector c of the plastic on the end face is not covered with the metal plate b, the IC card may be accidentally dropped on the floor or the end face may be hit against an object. In some cases, the plastic case a forming the connector part c may be deformed or damaged.
- CMOS-type integrated circuits built into IC cards are vulnerable to charged static electricity, and especially when the air dries, the internal discharge is caused by the discharge of static electricity to the connector. There is a problem that the integrated circuit is destroyed.
- a connector provided on an end face of an IC card is physically and electrostatically protected by a metal plate in order to solve these problems.
- the purpose is to provide an IC card.
- an IC card in which an integrated circuit board is sealed and contained, wherein the case is made of a card-shaped synthetic resin material in which the integrated circuit board is contained, and A connector provided on the end face for connecting the integrated circuit board to an external circuit; and a reinforcing metal plate covering the case.
- the end of the metal plate is L-shaped. It can be bent to cover the end surface having the connector portion and the surface of the case integrally, and to provide an IC force connecting the ground point of the semiconductor integrated circuit to the metal plate.
- the ends of the metal plates on the upper and lower surfaces of the case are bent into an L-shape, and are covered from the corners of the end surface to the vicinity of the i-pin of the connector portion.
- IC card is protected from external impact
- the grounding point of the built-in integrated circuit is connected to the metal plate, so the static electric field near the connector is discharged to the metal plate. This has the effect of protecting the integrated circuit.
- FIG. 1 is a perspective view showing an embodiment of the present invention
- FIG. 2 is a sectional view taken along a cutting line I--I
- FIG. 3 is a perspective view showing an example of a conventional IC card. is there .
- FIG. 1 is a perspective view showing one embodiment of the present invention
- FIG. 2 is a sectional view taken along a cutting line I-I shown in FIG.
- 1 indicates a card-like case made of a synthetic resin material, in which a CMOS type integrated circuit (IC) 2 is embedded.
- IC CMOS type integrated circuit
- a processor and a memory are configured.
- the connector section 11 is used to connect the IC 2 to an external device when writing / reading data, and is provided on a specific end face of the case 1. .
- a plurality of contact pins 21 are provided inside the connector section 11, and are connected to predetermined terminals 22 of the IC 2.
- 3a and 3b are metal plates for reinforcement. These metal plates 3 a and 3 b are attached to the upper and lower surfaces of case 1, respectively. L-shaped end L-shaped end 3 1a, 3 lbs at connector 1 11 of bus 1. The L-shaped ends 3 la and 31 b are bent so as to cover from the corner of the end face where the connector 11 is provided to the vicinity of the connector. Have been taken.
- Reference numeral 4 denotes a lead wire, which electrically connects the built-in grounding point 23 of the IC 2 and the metal plates 3 a and 3 b attached to the upper and lower surfaces of the case 1. Due to the metal plates 3a and 3b, the electrostatic discharge generated near the connector section 11 causes the bent L-shaped ends 3 of the metal plates 3a and 3b, respectively. 1a and 31b are provided close to the contact bin 21 so as to be guided to the contact bin 21 to prevent external static electricity from being discharged to the IC 2 via the contact bin 21. Have been.
- the metal is L-shaped ends 31a and 31b of the board are used to cover the connector including the corners of the edge of the 1 is free from deformation and breakage.
- the end "" of the reinforcing metal plate stuck on the upper and lower surfaces of the case of the IC card is bent into an L-shape so as to be close to the connector.
- the connector is protected from external shocks, and is protected from deformation and damage. Since it is connected to the ground point of the circuit, even if an electrostatic discharge occurs near the connector, it is discharged to the metal plate and the internal integrated circuit is protected by the discharge.
