Problems solved by technology

[0006] The problem to be solved by the present invention is: if the structure is such that when a card with a thinner thickness is inserted, the contacts and electrodes contact with a normal amount of deflection, then when a card with a thicker thickness is inserted, it may be caused by the insertion of the card. If the pressure is too large, the contacts and the electrodes are in contact with an abnormally large amount of deflection to deform or destroy the contacts.
On the contrary, if the structure is such that when a thicker card is inserted, the contacts and electrodes contact with a normal amount of deflection, and when a thinner card is inserted, it may be caused by too little insertion pressure of the card. Poor contact between contacts and electrodes

Embodiment 1

[0046] Two types of IC cards inserted into or pulled out from the IC card connector of the present invention will be described with reference to FIG. 4 .

[0047] The second IC card 12 shown in Fig. 4 (a-1), Fig. 4 (a-2) and Fig. 4 (b-1), Fig. 4 (b-2), Fig. 4 (b-3), Fig. The length of the first IC card 11 shown in 4 (b-4) is the same; its width is that the narrow side edge portion 18 of the first IC card 11 is substantially the same as the outside edge portion of the second IC card 12; its thickness Because the first IC card 11 is thicker and the second IC card 12 is thinner; in addition, the electrodes 16 of the first IC card 11 and the electrodes 20 of the second IC card 12 are different in number and shape.

[0048] More specifically, the above-mentioned first IC card 11 is made into a rectangle, and a wide side portion 17 and a narrow side portion 18 having a step difference are formed on both sides, and on the front side of the wide side portion 17, The electrode 16 is f...

Abstract

The invention relates to a connector for IC card, which can make the electrode of IC card with thick thickness and IC card with thin thickness contact with contact in housing in normal bending amount. The housing can insert and remove at least two IC cards of different thickness. A cover covvers on the housing after storing each part article. A contact for card is formed in one side of the bottom. A contact for card is formed in the other side of the top. A clapboard which can moves freely in the housing is mounted on the connector for IC card. On inserting IC card of one side, the clapboard is thrusted in and the IC card of one side is held between the two card contacts to release contacting. On inserting IC card of the other side, the IC card moves to the clapboard to make the IC card of the other side held between the clapboard and card contact of any side to release contacting.

Description

technical field [0001] The present invention relates to a connector for an IC card in which two cards of approximately the same length and width but different in thickness are inserted in opposite directions and connected to internal contacts. A connector for IC cards that creates a gap inside the housing so that two types of cards can come into reliable contact with the contacts. Background technique [0002] There are various proposals for IC card connectors that can insert multiple IC cards into one IC card connector, and the IC card connector shown in FIG. -100369 Bulletin). [0003] What the scheme shown in Fig. 8 represents is that these two kinds of the first IC card 11 and the second IC card 12 that can be roughly the same with width and length and a kind of card (not shown) that width is narrow and length is long and width and length There are four kinds of IC card connectors corresponding to one type of card (not shown) with the same length. [0004] In the case...
