Abstract
Abstract The invention relates to a card connector, and more particularly to a card connector having a function of half-locking a card 100 such as a memory card inserted into a card insertion space of a case 1 , in an extractable state. The invention provides a card connector which exhibits an excellent half-lock performance for a long term, and which, in a card-set state, exhibits an enhanced half-lock performance. In the card connector of the invention, a slider 3 is attached to the case 1 in a longitudinally movable manner, and the slider 3 is always elastically urged in the card ejecting direction. A half-lock mechanism 5 which engagingly holds the card in an extractable manner is disposed on the slider 3 . The half-lock mechanism 5 is formed with being divided into: a movable piece 52 which is configured by a resin-molded member, and which has an engaging projection 51 that engagingly holds the card 100 in an extractable manner; and a metal-made-spring member 55 which elastically urges the movable piece 52 in the direction along which the engaging projection 51 is to be fitted into a recess 110 of the card 100 . The card connector further has an auxiliary spring member 70 which, when the slider 3 is at the pushed position, increases the elastic force of the spring member 55.

Claim 1
Independent Claim
201 words
A card connector in which a slider which is to be pushed by a card that is inserted into a card insertion space of a case, to be moved from a stand-by position to a pushed position corresponding to a card-set position is attached to said case in a longitudinally movable manner, said slider at the pushed position being elastically urged in a card ejecting direction, said card connector has functions of locking said slider to the pushed position, and canceling the locked state of said slider which is locked at the pushed position, and said slider comprises a half-lock mechanism which engagingly holds said card in an extractable manner, wherein components of said half-lock mechanism are formed with being divided into: a movable piece which is configured by a flexurally deformable resin-molded member, and which integrally comprises an engaging projection that is to ride over said card inserted into the card insertion space to be fitted into a recess of said card, thereby engagingly holding said card in an extractable manner; and a metal-made spring member which elastically urges said movable piece in a direction along which said engaging projection is to be fitted into said recess of said card.
Claim 2
Dependent Claim
201 words
A card connector in which a slider which is to be pushed by a card that is inserted into a card insertion space of a case, to be moved from a stand-by position to a pushed position corresponding to a card-set position is attached to said case in a longitudinally movable manner, said slider at the pushed position being elastically urged in a card ejecting direction, said card connector has functions of locking said slider to the pushed position, and canceling the locked state of said slider which is locked at the pushed position, and said slider comprises a half-lock mechanism which engagingly holds said card in an extractable manner, wherein components of said half-lock mechanism are formed with being divided into: a movable piece which is configured by a flexurally deformable resin-molded member, and which integrally comprises an engaging projection that is to ride over said card inserted into the card insertion space to be fitted into a recess of said card, thereby engagingly holding said card in an extractable manner; and a metal-made spring member which elastically urges said movable piece in a direction along which said engaging projection is to be fitted into said recess of said card.
Claim 3
Dependent Claim
97 words
A card connector according to claim 1 , wherein said movable piece elongates in a cantilevered manner from said slider in a direction along which said card is to be inserted into the card insertion space, said engaging projection that is to ride on a side end face of said card to be fitted into said recess formed in a side end portion of said card is disposed at a tip end portion of said movable piece, and said spring member is accommodated and held in a recess formed in said slider and behind said movable piece.
Claim 4
Dependent Claim
97 words
A card connector according to claim 2 , wherein said spring member has a spring main portion which elongates along a back face of said movable piece that elongates in a cantilevered manner from said slider 3 said spring main portion being placed overlappingly with the back face, and said movable piece comprises a load dispersing portion in a place including a continuous place where said movable piece is continuous to said slider, a thickness of said load dispersing portion being changed in a manner that the thickness is smaller as further separating from said continuous place.
Claim 5
Dependent Claim
60 words
A card connector according to claim 3 , wherein, in said movable piece, a place which elongates from said place continuous to said slider to an intermediate point in the elongating direction is formed as said load dispersing portion, and a portion which elongates from an end of said load dispersing portion to a free end has a uniform thickness.
