Abstract
Abstract An electrical card connector comprises an ejector (4), a spring member (10) pushing the ejector backward and an ejecting bar (5) advanced by a force from the ejector, applying the force to a transmission mechanism. The ejector comprises an engaging member (12) guided by a cam member (7) provided in housing. The engaging member is engaged with and released from engaging bar. The cam member is provided as a cam groove (17) forming a circulation rout. The cam groove is formed so that the engaging member engages with the ejecting bar only when the ejector advances for card ejection and the engaging member (12) is released from the ejecting bar and the ejector (4) is moved backward under a pressure from the spring member (10) at other times than the card ejection.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
164 words
An electrical card connector, comprising: an arm having first and second guidance sections; an ejector guided by said first guidance section in a longitudinal direction of said arm and having a press button; a spring member provided between said first guidance section and said ejector to push said ejector backward toward an exit of said first guidance section; an ejecting bar pushed by said ejector and guided by said second guidance section; a cam groove provided in said arm; an engaging member engaging with said cam groove to guide said ejector and able to engage with said ejecting bar in said longitudinal direction; characterized in that said cam groove is formed so that said engaging member makes engagement with said ejecting bar only when said ejector is advanced by a pressure from said press button and is released from said engagement with said ejecting bar while said ejector is moved backward by a pressure from said spring member when said ejector is not advanced.
Claim 2
Dependent Claim
164 words
An electrical card connector, comprising: an arm having first and second guidance sections; an ejector guided by said first guidance section in a longitudinal direction of said arm and having a press button; a spring member provided between said first guidance section and said ejector to push said ejector backward toward an exit of said first guidance section; an ejecting bar pushed by said ejector and guided by said second guidance section; a cam groove provided in said arm; an engaging member engaging with said cam groove to guide said ejector and able to engage with said ejecting bar in said longitudinal direction; characterized in that said cam groove is formed so that said engaging member makes engagement with said ejecting bar only when said ejector is advanced by a pressure from said press button and is released from said engagement with said ejecting bar while said ejector is moved backward by a pressure from said spring member when said ejector is not advanced.
Claim 3
Dependent Claim
42 words

Claim 4
Dependent Claim
40 words
An electrical card connector according to claim 2, wherein said cam groove is divided into a plurality of areas having different depths, forming shoulders or slopes between said areas so that said engaging member can move only in one direction.
Claim 5
Dependent Claim
29 words
An electrical card connector according to claim 3, wherein a leaf spring is fixed to said ejector to push said engaging member to a bottom of said cam groove.
