Abstract
Abstract A card connector to be used for memory cards having a connector body and a plate-like frame attached to a frame member having a card insertion and removal opening(s), and a slider(s) operable in association with the card insertion/removal operation attached to the frame in an overlapping manner. The card connector is made thin with high mechanical strength assured. In particular, a plurality of cards may be overlappingly mounted on the card connector. Both release of the cards, held at setting positions and card unloading, are carried out by a single operation of actuators.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
144 words
A card connector comprising: a metallic plate-like frame having an upper side and a lower side; a frame member having a front end, a rear end, and provided at the front end thereof with a card insertion and removal opening; a connector body disposed at the rear end of said frame member; a slider longitudinally slidably attached to said frame; a spring for biasing said slider normally in the advancing direction thereof; a shaft swingingly attached to said frame; and an actuator; said frame being fitted in said frame member; said frame member having card guide grooves; said slider having at least one engagement pawl adapted to be opposite to the tip of a card when the card is inserted into said card guide grooves; and said shaft having one end swingingly connected to said slider and the other end opposite to said actuator.
Claim 2
Dependent Claim
144 words
A card connector comprising: a metallic plate-like frame having an upper side and a lower side; a frame member having a front end, a rear end, and provided at the front end thereof with a card insertion and removal opening; a connector body disposed at the rear end of said frame member; a slider longitudinally slidably attached to said frame; a spring for biasing said slider normally in the advancing direction thereof; a shaft swingingly attached to said frame; and an actuator; said frame being fitted in said frame member; said frame member having card guide grooves; said slider having at least one engagement pawl adapted to be opposite to the tip of a card when the card is inserted into said card guide grooves; and said shaft having one end swingingly connected to said slider and the other end opposite to said actuator.
Claim 3
Dependent Claim
71 words
A card connector as set forth in claim 1, wherein two shafts and two actuators are provided, the slider having the engagement pawls is attached to the frame at each of the upper and lower sides thereof, and the two shafts and two actuators are disposed such that one end of each shaft is swingingly connected to each slider and the other end of each shaft is opposite to each actuator.
Claim 4
Dependent Claim
253 words
In a card connector having a slider including at least one engagement pawl, and a connector body which houses, in a longitudinally movable manner, said slider, in which, when a card is inserted into said connector body, said slider is adapted moved to a retreat position with the tip of the card engaged with said engagement pawl, such that the card is held at a setting position, said card connector comprising, in addition to said connector body and said slider: a longitudinally movable actuator; a shaft swingingly attached to said connector body and having one end swingingly connected to said slider and the other end connected to said longitudinally movable actuator, projecting from the front end of said connector body; a swing member disposed on said connector body and provided at one end thereof with an engagement portion adapted to be engaged with and disengaged from a portion of the card held at said setting position to be engaged; and a cam surface formed at the tip of said actuator, which along with the other end of said swing member, is adapted to follow whereby play is formed between said actuator and the other end of said shaft, and when said actuator is pushed, said other end of said swing member is adapted to be displaced by said cam surface such that said engagement portion of said swing member is disengaged from said portion of the card to be engaged, while the play is removed and said shaft is interlocked with said actuator.
Claim 5
Dependent Claim
253 words
In a card connector having a slider including at least one engagement pawl, and a connector body which houses, in a longitudinally movable manner, said slider, in which, when a card is inserted into said connector body, said slider is adapted moved to a retreat position with the tip of the card engaged with said engagement pawl, such that the card is held at a setting position, said card connector comprising, in addition to said connector body and said slider: a longitudinally movable actuator; a shaft swingingly attached to said connector body and having one end swingingly connected to said slider and the other end connected to said longitudinally movable actuator, projecting from the front end of said connector body; a swing member disposed on said connector body and provided at one end thereof with an engagement portion adapted to be engaged with and disengaged from a portion of the card held at said setting position to be engaged; and a cam surface formed at the tip of said actuator, which along with the other end of said swing member, is adapted to follow whereby play is formed between said actuator and the other end of said shaft, and when said actuator is pushed, said other end of said swing member is adapted to be displaced by said cam surface such that said engagement portion of said swing member is disengaged from said portion of the card to be engaged, while the play is removed and said shaft is interlocked with said actuator.
