Abstract

PURPOSE:To eliminate loss of durability of a metal contact in contact with an electrode terminal by engaging small protrusions with small holes to integrate a card base with a circuit board, and exposing the terminal with a cutout between pectinated guides. CONSTITUTION:Small protrusions 32 are engaged with small holes 40 to be combined. An electronic component mounted on a circuit board 26 is contained in the recess of the rear surface of a card base 24, and the protrusions 32 protrude from the rear surface of the board 26. When the material of the base 24 is thermoplastic, the base 24 can be coupled with the board 26 by applying pressure to the protrusions while heating them. Accordingly, they can be combined without using a both-side adhesive tape or adhesive, and improper contact due to extension of the tape or the adhesive is eliminated. When an IC card is inserted into an opposite side connector, the metal contact 42 of the connector is contained in a cutout 30 in contact with an electrode terminal 38, thereby transmitting information.

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an IC card in which electronic components are incorporated into the card. This is to prevent damage and to not impair the durability of the contacts that come into contact with the electrode terminals.

For example, a conventional IC card has a card 10 as shown in FIG.
Some electrode terminals 12 are exposed on the surface. In such devices, when a person carries them around in their clothes, the electrode terminals 12 come into contact with clothes that are charged with static electricity due to friction, destroying electronic components such as internal semiconductors and causing important data to be lost. There was a risk of being destroyed. Furthermore, if there are no guide portions on both sides of the electrode terminals 12 and the spacing between the electrode terminals is narrow, there is a risk that the mating connector will come into contact with the adjacent electrode terminal and malfunction.

Therefore, as a solution to these problems, the third
An IC card 14 shown in the figure has been proposed. This has a guide portion 16 formed therein, and electrode terminals 18 are accommodated in the four inner portions 20 thereof.

According to the IC card 14 shown in FIG. 3, the electrode terminals 18 are housed in the recesses 20, so even if you carry them around inside your clothes, they will not come into contact with your clothes, thereby preventing damage due to static electricity. I can do it.

However, in such a structure, when inserting the IC card 14, the metal contact portion of the mating connector must climb over the platform-shaped slide portion 22 and come into contact with the electrode terminal 18, so that the metal contact portion is largely bent. For this reason, the metal contact portion tends to lose its springiness, resulting in a shortened lifespan. Further, since the electrode terminal 18 is housed in the recess 20, lumps and the like tend to accumulate, causing poor contact.

According to this invention, the metal contact portion of the mating connector comes into contact with the electrode terminal through the notch between the comb-shaped guides. According to this, since the comb-shaped guide does not have the platform-shaped sliding part 22 like the IC card 14 in FIG. 3,
The metal contact portion of the mating connector can contact the electrode terminal without climbing over the card base portion. Therefore, the metal contact portion of the mating connector is less bent, and its springiness can be maintained for a long period of time, thereby extending its life.
