A card connector includes a base, a shell and a contact. The contact has a contact portion, a first elastic portion and a second elastic portion. The contact portion abuts an electrode of an IC card inserted into a slot between the base and the shell. The first elastic portion extends from the contact portion in an insertion direction of the IC card and has a first end fixed to the base. The second elastic portion extends from the contact portion in an ejection direction of the IC card and has a second end fixed to the base.
1. A card connector comprising:
a base comprising synthetic resin, the base including an external terminal disposed on a back side in an insertion direction of an IC card;
a shell comprising metal, the shell configured to form a slot between the shell and the base into which the IC card is insertable; and
a contact comprising a contact portion abutting an electrode which is exposed from a surface of the IC card when the IC card is inserted into the slot, a first elastic portion extending from the contact portion in the insertion direction of the IC card and comprising a first end which is embedded in the base to be fixed to the base, and a second elastic portion extending from the contact portion in an ejection direction of the IC card and comprising a second end which is embedded in the base to be fixed to the base, the contact which is continuously formed from the first end to the second end via the contact portion.
2. The card connector of claim 1 , wherein
the first end is connected to the external terminal, and
a section between the first end and the external terminal is embedded in the base.
3. The card connector of claim 1 , wherein
the first elastic portion and the second elastic portion are disposed in symmetry at 180 degree with the contact portion as the center.
4. The card connector of claim 3 , wherein
the contact comprises a first transition portion leading from the contact portion to the first elastic portion and a second transition portion leading from the contact portion to the second elastic portion, and
the first transition portion and the second transition portion are slightly round.
5. The card connector of claim 1 , wherein
the shell comprises a leg at a side portion, the leg soldered on an electrode provided on a printed wiring board which is disposed under the base and is connected to the external terminal.
