초록 ▼

A PC card electrical connector with an expandable ejector includes an intermediate bar (10) having a cam follower pin (13); an ejector button section (20) for motion between a lock position (A2) where the ejector button section projects little more than a front end of the casing and a release position (C2) where the ejector button section projects far from the front end of the casing; a line spring (28) having a cam follower end (30); a first biasing spring (30) for biasing the ejector button section forwardly so that when the ejector button section is depressed a first time to release the follower end of the line spring from the lock position, the ejector button section is brought to the release position; and a second biasing spring (49) for biasing the intermediate bar onto a side of the ejector button section so that when the ejector button section is moved forward to the release position, the intermediate bar is turned to connect to the ejector button section, thereby making it possible that by depressing a second time the ejector button section to move the intermediate bar rearwardly, the receiving plate is brought to the removing position for removal of the PC card.

대표청구항 ▼

A PC card electrical connector with an expandable ejector, comprising: a housing having a receiving cavity therein; receiving means provided in said receiving cavity and being movable between a rearward receiving position wherein a PC card is pushed in said receiving cavity and a forward removing position wherein said PC card is removable from said receiving cavity; a casing secured to a side of said housing and having a bottom on which first and second cam channels and a guiding slot are formed; an ejector bar provided in said casing and linked to said receiving means at a rear end thereof; an intermediate bar provided in said casing so as to contact said ejector bar at a rear end thereof and having, near said rear end, a shaft for sliding engagement with said guiding slot and, at a lower front portion, a cam follower pin for sliding engagement with said second cam channel; an ejector button section provided in said casing for motion between a lock position where a front end portion of said ejector button section projects little more than a front end of said casing and a release position where said front end portion of said ejector button section projects far from said front end of said casing; first spring means extending rearwardly from a middle portion of said ejector button section and having a rear cam follower end for sliding engagement with said first cam channel to thereby hold said ejector button section at said lock position when said receiving means is at said receiving position; first biasing means provided between said ejector button section and said casing for biasing said ejector button section forwardly so that when said front end portion of said ejector button section is depressed a first time to release said follower end of said spring means from said lock position, said ejector button section is brought forwardly to said release position; and second biasing means provided between said intermediate bar and said casing for biasing said intermediate bar onto a side of said ejector button section so that when said ejector button sections is moved forward to said release position and separated from said intermediate bar, said intermediate bar is turned about said shaft past said ejector button section so that a front end of said intermediate bar is connected to a rear end of said ejector button section, thereby making it possible that by depressing a second time said front end of said ejector button section against said first biasing means to move said intermediate bar and said ejector bar rearwardly, said receiving means is brought to said removing position for removal of said PC card.
