Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a connector, and more
particularly to a card connector.
[0003] 2. The Related Art
[0004] With the development of the information industry,
communication devices, such as mobile phones, are widely used in
people's daily lives. The mobile phone need be equipped with an
electronic card to realize the communication function, and the
electronic card electrically connects with a circuit board of the
mobile phone by virtue of a card connector. So the card connector
is an essential component of the mobile phone.
[0005] In general, the card connector includes an insulating
housing, a plurality of conductive terminals, an ejection
mechanism, a card tray and a shielding shell. The insulating
housing defines an insertion space penetrating through a top and a
front thereof. The conductive terminals are integrally molded to
the insulating housing. The ejection mechanism is assembled in one
side of the insulating housing. The shielding shell is covered on
the insulating housing. The card tray defines a receiving space
therein, and is slidably inserted into the insertion space of the
insulating housing.
[0006] In use, when the electronic card need be inserted in the
card connector, the card tray is pushed rearward by an auxiliary
tool to make the card tray push the ejection mechanism to move
rearward, then the auxiliary tool is loosened to release the card
tray, so that the ejection mechanism rebounds forward to eject the
card tray out of the insertion space of the card connector. The
card tray is pulled out from the insertion space of the card
connector. So the electronic card is received in the receiving
space of the card tray, and the card tray together with the
electronic card is pushed rearward into the insertion space of the
card connector. When the electronic card need be withdrawn from the
card connector, the card tray is pushed rearward again by the
auxiliary tool to make the card tray push the ejection mechanism to
move rearward, then the auxiliary tool is loosened to release the
card tray, so that the ejection mechanism rebounds forward to eject
the card tray out of the insertion space of the card connector. The
card tray is pulled out from the insertion space of the card
connector. So the electronic card is taken out of the receiving
space of the card tray.
[0007] However, in the process of the electronic card being
inserted in or withdrawn from the card connector, the auxiliary
tool is needed to assist in ejecting the card tray out of the
insertion space of the card connector that brings an inconvenience
to users on account of the users seldom carrying around the
auxiliary tool with them.
SUMMARY OF THE INVENTION
[0008] An object of the present invention is to provide a card
connector. The card connector includes an insulating housing, a
plurality of conductive terminals, an ejection mechanism, a card
tray and at least one restraining element. The insulating housing
includes a bottom wall, a first side wall and a second side wall
extended upward from two opposite sides of the bottom wall, and a
rear wall extended upward from a rear end of the bottom wall and
connected with the first side wall and the second side wall. An
insertion space is surrounded among the bottom wall, the first side
wall, the second side wall and the rear wall. The rear wall defines
a recess passing through a top surface and a front surface thereof.
A rear end of a substantial middle of the second side wall defines
a sliding groove penetrating through a top and a front thereof and
communicating with the recess. A rear end of a bottom surface of
the sliding groove is concaved downward to form a heart-shaped
tracking groove joined end to end. The conductive terminals are
integrally molded to the bottom wall of the insulating housing. The
ejection mechanism includes a connecting element slidably disposed
in the sliding groove, a push button, a guiding element slidably
disposed in the sliding groove, a rotating element rotatably
disposed in the recess and an elastic element restrained between a
rear inner surface of the second side wall and the connecting
element. The guiding element has two protruding pillars. One
protruding pillar is pivoted in the connecting element and the
other protruding pillar is slidably disposed in the tracking
groove. The push button is mounted to the front end of the
connecting element and projects beyond a front surface of the
insulating housing. One end of the rotating element is capable of
rotating to the insertion space, and a rear surface of the rotating
element abuts against the front surface of the rear wall for
limiting the other end of the rotating element in the recess. The
card tray is slidably assembled to the insertion space of the
insulating housing. The restraining element is restrained in one
side of the card tray.
[0009] As described above, in the process of the electronic card
being inserted in or withdrawn from the card connector, the card
tray is ejected out of the insertion space of the card connector by
virtue of the ejection mechanism. So no auxiliary tool is needed to
assist in ejecting the card tray out of the insertion space of the
card connector so as to bring a convenience to users.

53 to slide rearward and towards recess 141, the pushing block 532
of the guiding element 53 pushes against the blocking portion 543
of the rotating element 54 to make the rotating element 54 to
rotate anticlockwise pivoting the pivot pillar 142 so that the
abutting portion 544 projects into the insertion space 15 for
pushing against the card tray 60 to move forward, at the moment,
the two elastic portions 32 break away from the two cavities 613 of
the card tray 60, so the card tray 60 is ejected out of the
insertion space 15 of the card connector 100. Release the push
button 52, the elastic element 55 releases the elastic potential
energies to elastically push the connecting element 51 with the
push button 52 to move forward and the connecting element 51 drive
the protruding pillar 534 of the guiding element 53 to slide
rearward and towards the blocking wall 137 until the protruding
pillar 534 resists against the locking portion 138.
[0034] At last, pull out the card tray 60, the electronic card 200
is received in the receiving space 611 of the card tray 60, push
the card tray 60 together with the electronic card 200 therein into
the insertion space 15. The card tray 60 pushes against the
abutting portion 544 of the rotating element 54 to move rearward so
as to drive the rotating element 54 to rotate clockwise to be
located in the recess 141. At least one restraining element 30 is
restrained in one side of the card tray 60. The elastic portions 32
of the restraining elements 30 are restrained in the two cavities
613 of the base board 61 of the card tray 60.
[0035] Referring to FIG. 1 to FIG. 6, when the electronic card 200
need be withdrawn from the card connector 100, push the push button
52 rearward to push the connecting element 51 to move rearward so
as to make the connecting element 51 drive the protruding pillar
534 of the guiding element 53 to slide rearward and towards the
blocking wall 137 to break away from the locking portion 138. At
the moment, the elastic element 55 shows a compressing status to
accumulate elastic potential energies. Release the push button 52,
the elastic element 55 releases the elastic potential energies to
elastically push the connecting element 51 with the push button 52
to move forward and the connecting element 51 drive the protruding
pillar 534 of the guiding element 53 to slide forward until the
transverse portion 501 of the pushing portion 511 abuts against two
opposite sides of an inner surface of a front sidewall of the
sliding groove 133. At the moment, the pushing portion 511 with the
push button 52 projects out of the insulating housing 10.
[0036] Then, push the push button 52 rearward again to push the
connecting element 51 to move rearward so as to make the connecting
element 51 drive the protruding pillar 534 of the guiding element
53 to slide rearward and towards recess 141, the pushing block 532
of the guiding element 53 pushes against the blocking portion 543
of the rotating element 54 to make the rotating element 54 to
rotate anticlockwise pivoting the pivot pillar 142 so that the
abutting portion 544 projects into the insertion space 15 for
pushing against the card tray 60 together with the electronic card
200 therein to move forward, at the moment, the two elastic
portions 32 break away from the two cavities 613 of the card tray
60 together with the electronic card 200 therein, so the card tray
60 together with the electronic card 200 therein is ejected out of
the insertion space 15 of the card connector 100. Pull out the card
tray 60 together with the electronic card 200 therein, and take the
