Card connector with ejector

Claim 2

A card connector for use with a card having a rear edge and opposite side edges comprising: a frame which includes a cavity for receiving said card and walls for closely guiding said card in movement rearwardly into said cavity and forwardly out of said cavity; an ejector movably mounted on said frame and having card engaging portions positioned to engage said rear edge of said card when said card is fully inserted into said cavity; a depressible ejector button movably mounted on said frame; a lever pivotally mounted on said frame and having first and second parts pivotally coupled respectively to said button and to said ejector, so depression of said button causes movement of said ejector in a forward direction to eject said card; said ejector having first and second spaced locations that are each slidably mounted directly on said frame to move accurately in said rearward and forward directions, and said card engaging parts include two spaced parts located to abut said card rear edge at locations thereon lying adjacent to the opposite side edges of the card; said first and second locations being spaced apart by more than half the width of said card; said spaced parts which engage said card rear edge are each slidably mounted on said frame to form said first and second locations that are each slidably mounted on said frame.

Claim 3

The card connector described in claim 1 wherein: said spaced parts which engage said card rear edge are each slidably mounted on said frame to form said first and second locations that are each slidably mounted on said frame.

Claim 4

The card connector described in claim 1 wherein: said first and second locations are spaced apart along a direction perpendicular to the direction of said card movement; said ejector is separately slidably mounted on said frame at said first and second locations and also at a separate third location spaced forward of said first and second locations, with each of said locations including apart slidably received in a separate groove extending in said forward and rearward directions.

Claim 5

A card connector for use with a card having a rear edge and opposite side edges comprising: a frame which includes a cavity for receiving said card and walls for closely guiding said card in movement rearwardly into said cavity and forwardly out of said cavity; an ejector movably mounted on said frame and having card engaging parts positioned to engage said rear edge of said card when said card is fully inserted into said cavity; a depressible ejector button which is slidably mounted on said frame to move in said rearward and forward directions between extreme rearward and forward positions; a lever pivotally mounted on said frame and having first and second parts pivotally coupled respectively to said button and to said ejector, so depression of said button causes movement of said ejector in a forward direction to eject said card; said ejector being slidably mounted directly on said frame to move accurately in said rearward and forward directions, and said card engaging portions include two spaced parts located to abut said card rear edge at locations thereon lying adjacent to the opposite side edges of the card; said button includes a rearward end having a shaft extending perpendicular to said forward and rearward directions and having an enlarged tip; said lever has a hole that receives said shaft and which can pivot thereon, said lever having first and second faces; said button is installable on said frame by moving said button rearwardly into said frame until said button passes said most forward position, said button and frame having stopper parts that normally prevent forward movement of said button forwardly past said extreme forward position; said lever hole is elongated and has a wide first end which is positioned to receive said tip of said shaft only when said button lies forward of said extreme forward position.

Claim 6

A card connector for use with a card having a rear edge and opposite side edges comprising: a frame which includes a cavity for receiving said card and walls for closely guiding said card in movement rearwardly into said cavity and forwardly out of said cavity; an ejector movably mounted on said frame and having card engaging parts positioned to engage said rear edge of said card when said card is fully inserted into said cavity; a depressible ejector button which is slidably mounted on said frame to move in said rearward and forward directions between extreme rearward and forward positions; a lever pivotally mounted on said frame and having first and second parts pivotally coupled respectively to said button and to said ejector, so depression of said button causes movement of said ejector in a forward direction to eject said card; said ejector being slidably mounted directly on said frame to move accurately in said rearward and forward directions, and said card engaging portions include two spaced parts located to abut said card rear edge at locations thereon lying adjacent to the opposite side edges of the card; said button includes a rearward end having a shaft extending perpendicular to said forward and rearward directions and having an enlarged tip; said lever has a hole that receives said shaft and which can pivot thereon, said lever having first and second faces; said button is installable on said frame by moving said button rearwardly into said frame until said button passes said most forward position, said button and frame having stopper parts that normally prevent forward movement of said button forwardly past said extreme forward position; said lever hole is elongated and has a wide first end which is positioned to receive said tip of said shaft only when said button lies forward of said extreme forward position.
