ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to electronic apparatuses, and more particularly to an electronic card-ejectable card connector capable of receiving at least two different kinds of electronic cards and ejecting the electronic card semi-automatically by pushing the card a second time after pushing the card into the card connector a first time.
2. Description of the Related Art
A conventional electronic card connector
70
, as shown in
FIG. 8
, is composed of a base frame
71
, a plurality of first and second contact pins
73
, and a card ejecting device
75
. The base frame
71
can accommodate first and second electronic cards to be inserted thereinto. The card ejecting device
75
includes a slide member
76
, which is formed of an arched portion
77
for accommodating the inserted first electronic card and a front end
78
for accommodating the inserted second electronic card.
However, the arched portion
77
of the slide member
76
is specifically designed to accommodate a complementary arched portion positioned at a front left side of a memory stick (MS) electronic card such that the aforesaid card connector
70
is inefficient in design and mould processing of its parts and is high in production cost.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide an electronic card-ejectable card connector, which is structurally simple, low in production cost, and capable of receiving at least two kinds of electronic cards and ejecting an electronic card semi-automatically.
The foregoing objective of the present invention is attained by the electronic card-ejectable card connector, which is composed of a base frame, a cover shell, two units of contact pins, and a card ejecting device. The base frame includes a concave portion longitudinally in proximity of a lateral side thereof and is covered with the cover shell thereon such that a receiving space having at least two different sized chambers is formed between the base frame and the cover shell. The receiving space has an exit at a front end thereof for inserting at least two different electronic cards and a butt at a rear end thereof. The cover shell includes a top plate having a slot, an elastic piece bent downwards from the slot of the top plate thereof, and at least one lateral wall bent vertically downwards from at least one side thereof and having a through hole at a predetermined position. The two units of contact pins are mounted on the base frame and respectively inside the at least two different sized chambers. The card ejecting device includes an elongated guide member, a positioning bar, and a biasing member. The guide member has a guide recess at a top side thereof and is movably mounted inside the concave portion of the base frame for traversing longitudinally in a predetermined section. The guide recess defines a circuit inside having a first stop point and a second stop point and is provided with a variety of elevations so as to be effective in non-return. The guide member has a crooked portion at rear end thereof extending transversally towards inside of the base frame and a tip portion positioned at a front end thereof. The positioning bar has a body portion held against by the elastic piece of the cover shell, a crank portion positioned at a rear end thereof and pivotably engaging the through hole of the lateral wall for pivoting at a small angle towards random directions by means of an external strength, and a hooked portion bent downwards from a front end thereof for slidably engaged in the guide recess. The biasing member has two ends respectively connected with the base frame and the guide member and provides rebounding resilience to bring the guide member back while the guide member moves backwards to drive the biasing member to be extended.
