Card connector
The card connector, into which an IC card having a plurality of pads arranged in parallel at front and back positions is inserted, includes a plurality of contacts each contacting a corresponding one of the plurality of pads of the IC card and a base member that supports the plurality of contacts. Each of the plurality of contacts has a first and a second elastic piece each having a contact point portion that electrically contacts a pad of the IC card. The first and second elastic pieces are formed such that contact pressures of the respective contact point portions against the pads are different from each other. The plurality of contacts is arranged on the base member in parallel at front and back positions and a first and a second contact piece are arranged in an opposite manner in contacts aligned linearly at front and back positions.
1. A card connector into which an IC card is inserted into, the IC card having a plurality of external contact points arranged in parallel at a first row position and a second row position, said card connector comprising:
at least two contacts of a plurality of contacts configured to contact two corresponding external contact points of said plurality of external contact points of said IC card;
a base member configured to support the at least two contacts of the plurality of contacts; and
a cover member configured to form a card accommodation space into which said IC card is inserted when the cover member is overlapped on said base member; wherein
said IC card is inserted into said card accommodation space through a card insertion opening in which said card accommodation space opens,
the at least two contacts of said plurality of contacts including a first and a second elastic piece, the first and second elastic pieces each having a contact point portion that electrically contacts an external contact point of said IC card,
the first and second elastic pieces being configured such that a contact pressure of the first elastic piece against a corresponding external contact point is different from a contact pressure of the second elastic piece against another corresponding external contact point, and
said plurality of contacts being arranged on the base member in parallel at a first row position and a second row position in an IC card insertion direction, the first elastic piece in the first row position being linearly aligned with the second elastic piece in the second row position, and the second elastic piece in the first row position being linearly aligned with the first elastic piece in the second row position.
2. The card connector according to claim 1 , wherein said first and second elastic pieces of said contact are formed to have the same length and different widths.
3. The card connector according to claim 1 , wherein said first and second elastic pieces of said contact are formed to have different lengths and the same width.
4. The card connector according to claim 1 , wherein said first and second elastic pieces of said contact are formed to have different lengths and different widths.
5. The card connector according to claim 1 , wherein a contact pressure of the first elastic piece is greater than a contact pressure of the second elastic piece.
