PC card electrical connector

Claim 2

A PC card electrical connector for receiving a PC card having a plurality of contact elements provided at a front end, comprising: a housing having a pair of guide sections for guiding sides of said PC card into said housing and a connector section connected to rear portions of said guide sections and having a fulcrum projection; a slider member provided on said connector section for sliding movement along said guide sections and having abutment portions for abutment against said front end of said PC card; an ejector bar connected to said ejector lever and movable rearwardly when depressed; and said ejector lever having a first push portion provided near said fulcrum projection for pushing forwardly said slider member and a second push portion spaced from said fulcrum projection further than said first push portion for applying spring forces to said slider at least after said PC card is disconnected from said connector section by said first push portion said elector bar directly connected to said ejector lever at an end opposite to said first and second push portions with respect to said fulcrum so that when it is depressed with a force, it rotates said elector lever counterclockwise to elect said PC card with said pushing force.

Claim 3

A PC card electrical connector according to claim 1, wherein said second push portion is made in a form of cantilever beam spring extending from said ejector lever and flexes when said slider member moves forwardly and further moves said PC card with spring forces when said PC card is disconnected from said connector section.

Claim 4

A PC card electrical connector for connection with a PC card having a plurality of contact elements provided at a front end, comprising: a housing having a pair of guide sections for guiding sides of said PC card into said housing and a connector section connected to rear portions of said guide sections and having a fulcrum projection; a slider member provided on said connector section for sliding movement along said guide sections and having abutment portions for abutment against said front end of said PC card; an ejector lever rotatable about said fulcrum projection of said housing and having a push portion provided near said fulcrum projection; an ejector bar connected directly to said ejector lever at an end opposite to said push portion with respect to said fulcrum and movable rearwardly when depressed so that when it is depressed with a force, it rotates said elector lever counterclockwise to disconnect said PC card from said connector section; a spring provided between said slider member and said housing and elastically deformed as said slider member is moved rearwardly; and lock means for locking said spring in said elastically deformed state when said PC card is inserted into said housing and releasing said lock when said PC card is disconnected from said connector section so that said spring further pushes said disconnected PC card toward removal.

Claim 5

A PC card electrical connector for connection with a PC card having a plurality of contact elements provided at a front end, comprising: a housing having a pair of guide sections for guiding sides of said PC card into said housing and a connector section connected to rear portions of said guide sections and having a fulcrum projection; a slider member provided on said connector section for sliding movement along said guide sections and having abutment portions for abutment against said front end of said PC card; an ejector lever rotatable about said fulcrum projection of said housing and having a push portion provided near said fulcrum projection; an ejector bar connected directly to said ejector lever at an end opposite to said push portion with respect to said fulcrum and movable rearwardly when depressed so that when it is depressed with a force, it rotates said elector lever counterclockwise to disconnect said PC card from said connector section; a spring provided between said slider member and said housing and elastically deformed as said slider member is moved rearwardly; and lock means for locking said spring in said elastically deformed state when said PC card is inserted into said housing and releasing said lock when said PC card is disconnected from said connector section so that said spring further pushes said disconnected PC card toward removal.

Claim 6

A PC card electrical connector for connection with a PC card having a plurality of contact elements provided at a front end, comprising: a housing having a pair of guide sections for guiding sides of said PC card into said housing and a connector section connected to rear portions of said guide sections and having a fulcrum projection; a slider member provided on said connector section for sliding movement along said guide sections and having abutment portions for abutment against said front end of said PC card; an ejector lever rotatable about said fulcrum projection of said housing and having a push portion provided near said fulcrum projection; an ejector bar connected directly to said ejector lever at an end opposite to said push portion with respect to said fulcrum and movable rearwardly when depressed so that when it is depressed with a pushing force, it rotates said elector lever counterclockwise to disconnect said PC card from said connector section; and a spring provided between said slider member and said housing and elastically deformed as said slider member is moved rearwardly by said PC card inserted and having a spring force smaller than a connection force between said PC card and said connector section so as to push said disconnected PC card toward further removal.

Claim 7

A PC card electrical connector for connection with a PC card having a plurality of contact elements provided at a front end, comprising: a housing having a pair of guide sections for guiding sides of said PC card into said housing and a connector section connected to rear portions of said guide sections and having a fulcrum projection; a slider member provided on said connector section for sliding movement along said guide sections and having abutment portions for abutment against said front end of said PC card; an ejector lever rotatable about said fulcrum projection of said housing and having a push portion provided near said fulcrum projection; an ejector bar connected directly to said ejector lever at an end opposite to said push portion with respect to said fulcrum and movable rearwardly when depressed so that when it is depressed with a pushing force, it rotates said elector lever counterclockwise to disconnect said PC card from said connector section; and a spring provided between said slider member and said housing and elastically deformed as said slider member is moved rearwardly by said PC card inserted and having a spring force smaller than a connection force between said PC card and said connector section so as to push said disconnected PC card toward further removal.
