Problems solved by technology

In this case, however, when IC cards with worse thickness tolerances are put on the market, protrusions formed of sheet metal may come into contact with conductive sheets of the IC card, causing electrical failures such as short circuits

Abstract

A card connector for an IC card according to the present invention is provided with a preventive wall of an anti-floating mechanism in an ejector mechanism on a substrate, for suppressing the floating-up of the inserted IC card. Also, projections of an erroneous insert prevention mechanism for inhibiting the opposite insert of the card are provided with a sheet metal cover to prevent the IC card from floating up or being erroneously inserted, so that the IC card is not damaged and no short-circuit accident occurs. The card connector for an IC card is constructed into a hollow flat housing formed of a substrate and a metal sheet cover combined therewith, having the anti-floating mechanism for suppressing the floating-up of the IC card and the erroneous insert prevention mechanism for preventing the IC card from being inserted in such a manner that the rear end is directed forward.

Description

technical field [0001] The present invention relates to a card connector, in particular to an IC card connector into which an IC card is inserted. Background technique [0002] Recently, IC cards in which an IC portion called an IC chip is incorporated are becoming widely used, and therefore, a card connector for inserting the IC card is widely required. This type of conventional card connector is composed of a base and a cover, and is required to have an overall small height and sufficient strength to withstand the insertion and removal of an IC card in order to meet market demands. In addition, such a card connector is required to have a certain strength, be able to hold the IC card, and withstand violent twisting of the IC card. To achieve this strength, the card connector includes a sheet metal cover on the top surface of the substrate in such a way that the metal plate is bonded to the substrate of the card connector. There are similar requirements for a so-called rev...
