Patent ID: 8109794

Claim:
A card adaptor, comprising: a case member forming a card insertion space; an insulator having an attaching portion in said case member; and a contacting portion of a contact to be contacted with a contact pad which is disposed on one principal face of a card to be inserted in the case member, the contact being placed in the card insertion space, wherein: between the attaching portion and the contacting portion, a first plate spring piece portion extends in a cantilevered manner within a contact housing groove disposed on the bottom face of the card insertion space opposed to one principal face of the card on which the contact pad is disposed, said first plate spring piece portion having on one side a first fulcrum portion which is continuously integrated with the attaching portion and always butts against a bottom face of the contact housing groove, said first plate spring piece portion extending in said cantilevered manner from said first fulcrum portion in a direction opposite to a card insertion direction so as to be elastically deformable in a thickness direction of said card, the first plate spring piece portion gradually separating from the bottom face of the contact housing groove as said first plate spring piece portion extends away from said first fulcrum portion; a second plate spring piece portion extended from said first plate spring piece portion having on one side a second fulcrum portion which is another side of said first plate spring piece portion which butts against the bottom face of the contact housing groove when the first plate spring piece portion is flexurally deformed with setting the first fulcrum portion as a first fulcrum is formed in a shape where said second plate spring piece portion extends at an inclination angle in a cantilevered manner from said second fulcrum portion in the card insertion direction so as to be elastically deformable in the card thickness direction, and another side of said second plate spring piece portion is the contacting portion to be contacted with said contact pad of said card; and an external connection terminal is continuously integrated with a side of said attaching portion which is opposite to the first plate spring piece portion.
