Abstract
Abstract The invention relates to an electrical card connector (hereinafter referred to as "connector") which is used for a card C such as an IC card. The invention proposes a structure in which scratches are not formed on the surface of the card when the card C is inserted into the connector or when the card C is ejected from the connector. The connector has a body 1, a slider 4, and a cover 7. The slider 4 is disposed so as to be slidable. The connector has a contact position regulating mechanism 8 which, when the slider 4 is in an initial position, retracts a contact 26 to the outside of a card insertion space S1 and, when the slider 4 reaches a pushed position, causes the contact 26 to protrude into the card insertion space S1. When the slider 4 is in the initial position, the contact position regulating mechanism 8 causes the contact to be retracted to the outside of the card insertion space. When the slider 4 is in the pushed position, the contact is caused to protrude into the card insertion space by the function of the contact position regulating mechanism 8.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
256 words
An electrical card connector comprising: a body having a card insertion space; a slider which is held by said body so as to be slidable in card inserting and ejecting directions between an initial position on the side of a rear portion of said body and a pushed position on the side of a front portion of said body; elastically urging means for always elastically urging said slider in said card ejecting direction; an engaging portion which is disposed in said slider and which protrudes into said card insertion space, said engagement portion being engaged with a tip end of a card which is inserted into said card insertion space and being pushed and moved in the card inserting direction; a contact piece member which is held by said body and which comprises a contact which uses an external contact on a surface of said card as a counter part, said contact piece member having elasticity for always urging said contact in a direction along which said contact protrudes into said card insertion space; and a contact position regulating mechanism which is interposed between said contact piece member and said slider, which, when said slider is at the initial position, retracts said contact of said contact piece member to the outside of said card insertion space against the elasticity of said contact piece member, and which, as said slider slides from the initial position to the pushed position, allows said contact to protrude into said card insertion space by the elasticity of said contact piece member.
Claim 2
Dependent Claim
197 words
An electrical card connector according to claim 1, wherein said contact piece member elongates from an end portion of said body in the card inserting direction along the card ejecting direction, an end portion of said contact piece member is bent and formed as an angled portion, a top portion of said angled portion is formed as a contact, and said contact position regulating mechanism comprises: a projecting piece which is cut and raised to protrude in the card ejecting direction from a slope portion positioned closer to a basal portion of said contact piece member than said top portion of said angled portion; a pressing face which is formed on said slider, and which, when said slider is at the initial position, overlaps said projecting piece to prevent said projecting piece from being displaced in a direction toward said card insertion space by the elasticity of said contact piece member; and an opening which is formed in a portion adjacent to said pressing face in said slider, and which allows said projecting piece to be displaced in the direction toward said card insertion space as said slider slides from the initial position to the pushed position.
Claim 3
Dependent Claim
87 words
An electrical card connector according to claim 2, wherein, in the middle of the insertion of said card, when an external contact forming region of said card does not reach a position opposing said contact of said contact piece member, a condition in which said pressing face of said slider overlaps said projecting piece is maintained, and, when said external contact forming region of said card reaches said position opposing said contact of said contact piece member, an opening of said slider corresponds to said projecting piece.
Claim 4
Dependent Claim
219 words
An electrical card connector according to claim 1, wherein said slider comprises an arm which has elasticity, in which a basal portion is cantilevered by said slider, and which elongates in the card inserting direction, a tip end portion of said arm has a head portion which protrudes in said card insertion space when said slider is at the initial position, an upward slope face which is formed in said head portion functions as said engaging portion which is to be engaged with said tip end of said card, an engagement pawl is disposed in said head portion, and said body comprises: a guide face on which, when said slider is pushed and moved by said card from the initial position to the pushed position, said engagement pawl slides, thereby preventing said head portion from being pressed by said card; an opening which is disposed adjacent to said guide face, and in which, when said slider reaches the pushed position, said engagement pawl of said head portion which is pushed against the elasticity of said arm by said card falls in said opening, thereby allowing said tip end of said card to ride over said head portion; and an engaging portion which is to engage with said engagement pawl which is in the opening, in the card ejecting direction.
Claim 5
Dependent Claim
32 words
An electrical card connector according to claim 4, wherein said slider, said arm, said head portion, and said engagement pawl are formed as an integrally molded body made of a synthetic resin.
Claim 6
Dependent Claim
104 words
An electrical card connector according to claim 4, wherein said card insertion space is a space between a flat-plate partition wall which is disposed in said body and which forms a slider housing space on the side of a back face, and a face of a cover which is mounted on said body, said cover face opposing said partition wall, and, when said engagement pawl is engaged with said engaging portion, said card is pressingly held in an elastic manner by said head portion which is elastically in contact with said card due to the elastic restoring force of said arm, and said cover.
Claim 7
Dependent Claim
81 words
An electrical card connector according to claim 2, wherein said card insertion space is a space between a flat-plate partition wall which is disposed in said body and which forms a slider housing space on the side of a back face, and a face of a cover which is mounted on said body, said cover face opposing said partition wall, and an opening through which said angled portion of said contact piece member can pass is formed in said partition wall.
Claim 8
Dependent Claim
77 words
An electrical card connector according to claim 4, wherein said card insertion space is a space between a flat-plate partition wall which is disposed in said body and which forms a slider housing space on the side of a back face, and a face of a cover which is mounted on said body, said cover face opposing said partition wall, and an opening into which said head portion is loosely fitted is formed in said partition wall.
Claim 9
Dependent Claim
32 words
An electrical card connectors according to any one of claims 1 to 8, wherein said electrical card connector is a multipolar electrical card connector comprising a number of said contact piece members.
