Ic card

Abstract

Abstract PURPOSE:To insert accurately an IC card into a connector of an external device by providing a protrusions between adjacent terminals. CONSTITUTION:Terminals 5a to 5f provided on a printed board 1 are plated with gold on flat surfaces on the same side, and protrusions 8 are provided between adjacent ones of the terminals 5a to 5f so as to separate the terminals from each other. When a connector 10 of an external device 9 is provided with grooves 11 for respective engagement with the protrusions 8, it is possible to bring the terminals 5a to 5f into accurate contact with corresponding connector terminals 12 of the connector 10. With the protrusions 8 provided, the danger of short-circuit can be precluded even where the terminals are set as close as possible to each other.
