Abstract
An IC card arranged so that a connector cannot come off a frame during an assembly process in which the connector and a circuit board are accommodated in the frame and panels are thereafter attached to obverse and reverse surfaces of the frame. Projections on sides of the connector and resilient engaging/fixing hooks with oblique surfaces on the frame are engaged. As the connector is forced into the frame, the projections of the connector are brought into engagement with and temporarily deflect the engaging/fixing hooks of the frame. The connector is thereby fixed firmly on the frame.
Claims10
An IC card for insertion into and connection to an external unit, said IC card comprising:
- a circuit board having a major surface and at least one edge;
- electronic parts mounted on the major surface;
- at least one connector fixed on the edge of said circuit board and electrically connected to said electronic parts;
- a frame receiving said circuit board and said connector, laterally surrounding said circuit board and said connector with said circuit board fixed to said frame and a face of said connector exposed;
- connector fixation means fixing said connector to said frame;
- and
- a pair of panels attached to obverse and reverse surfaces of said frame, covering said circuit board and said connector.
A method of manufacturing an IC card having a frame, a circuit board on which electronic parts are mounted, a connector electrically connected to the electronic parts, and panels attached to opposite surface of the frame, the circuit board and the connector being accommodated in said frame, said method comprising:
- fixing the connector on the circuit board by soldering;
- fitting in the frame the circuit board on which the connector is fixed, fixing the circuit board on the frame by caulking, and fixing the connector on the frame with connector fixation means;
- and
- attaching the panels to the opposite surfaces of the frame.
