Abstract:
An electrical card connector for holding an inserted electrical card, the card having a plurality of surfaces, and preventing scratching of the surfaces of the inserted electrical card, comprising:a body having a partition wall and parallel spaced apart frames extending from both ends of said partition wall, said partition wall and parallel spaced apart frames partly defining a card insertion space, said card insertion space defining card inserting and ejecting directions;a slider mounted on said body so as to be slidable along said body in the card inserting and ejecting directions between an initial position and a pushed-in position;spring means mounted to said housing for engaging said slider to bias said slider in said ejecting direction;said slider having at least one arm formed as part of said slider, said at least one arm having a basal portion and a head portion including an engaging portion, said head portion protruding into said card insertion space, said engagement portion being engaged with the inserted electrical card when the card is inserted into said card insertion space and moved in the card insertion direction;at least one contact piece member attached to said body, said at least one contact piece member having a basal portion, a curved section extending from said basal portion, said curved section having a top defining a contact portion, said basal portion and said curved section extending into said card insertion space, and a projecting piece situated adjacent to a side edge of said basal portion, said projecting piece extending parallel in the electrical card ejection direction, said contact portion having an external contact surface for contacting a surface of the inserted electrical card, said at least one contact piece member having elasticity for urging said contact portion into said card insertion space; anda contact position regulating mechanism comprising said projecting piece, an opening in said slider associated with each of said at least one contact piece member, and a pressing portion extending into said opening such that when said slider is in said initial position said pressing face overlaps said projecting piece preventing said projecting piece from being displaced upwardly into said opening by the elasticity of said at least one contact piece member, said opening allowing said projecting piece to be displaced upwardly therein as said slider slides from said initial position to said pushed-in position, wherein, in the middle of the insertion of an electrical card between said initial position and said pushed-in position, before an external contact forming region of the electrical card reaches the initial position opposing said contact of said contact piece member, a condition in which said pressing face overlaps said projecting piece is maintained, and, when the external contact forming region of the electrical card reaches the pushed in position opposing said contact of said contact piece member, said projecting piece extends into said opening.
