Abstract
Abstract The electrical connector according to the present invention is adapted to guide a card in the front-to-back direction thereof by left- and right-hand guides projecting from the electrical connector body. The electrical connector body incorporates a card ejecting mechanism, which comprises a swingable cam, a card pushing portion formed at the cam, and a lever connected to a mounting portion of the cam. The ejecting mechanism having the arrangement above-mentioned does not project on and under the electrical connector, thus enabling the electrical connector to be made thin and in small sizes.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
174 words
A multipolar electrical connector comprising: contact pin groups; an electrical connector body from which said contact pin groups project; guides rearwardly extending from said electrical connector body at the ends of both lateral sides thereof, said guides being adapted to guide, in the front-to-back direction, a card provided in the front end surface thereof with pin insertion holes corresponding to said contact pin groups, while said guides respectively come in slide contact with both lateral sides of said card; a cam swingably pin-connected to said electrical connector body at the end of the left or right side thereof; a card pushing portion formed on said cam at a portion thereof, said card pushing portion being adapted to be moved toward or away from one end side of a card setting space in the right-to-left direction thereof when said cam is swung, said card setting space being formed between said left and right-hand guides; and a mounting portion formed on said cam at another portion thereof and connected to an actuator for swinging said cam.
Claim 2
Dependent Claim
174 words
A multipolar electrical connector comprising: contact pin groups; an electrical connector body from which said contact pin groups project; guides rearwardly extending from said electrical connector body at the ends of both lateral sides thereof, said guides being adapted to guide, in the front-to-back direction, a card provided in the front end surface thereof with pin insertion holes corresponding to said contact pin groups, while said guides respectively come in slide contact with both lateral sides of said card; a cam swingably pin-connected to said electrical connector body at the end of the left or right side thereof; a card pushing portion formed on said cam at a portion thereof, said card pushing portion being adapted to be moved toward or away from one end side of a card setting space in the right-to-left direction thereof when said cam is swung, said card setting space being formed between said left and right-hand guides; and a mounting portion formed on said cam at another portion thereof and connected to an actuator for swinging said cam.
Claim 3
Dependent Claim
44 words
