## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention generally relates to an electrical card connector, and more particularly to an electrical card connector having an ejecting mechanism.
2. Description of Prior Art
Modern times, the PC card is always used as an external equipment for increase the storage of the electrical consumer products, like Mobile phone, Digital camera, etc. The electrical card connector is used for electrically connecting the PC card and the electrical consumer products. An ejecting mechanism is used on the card connector for ejecting the card from the card connector.
TW. Pat. No. 325154 and TW. Pat. No. 314665 disclose a kind of nonage ejecting mechanism. The user just presses a knob one time to ejecting the card from the ejecting member. However, this kind of ejecting mechanism has a long part beyond the electrical card connector when the card is inserted into the electrical card connector. Therefore, the ejecting mechanism is easily broken when an improper force working on the part beyond the electrical card connector.
Another kind of ejecting mechanism is appeared for resolving this problem. U.S. Pat. No. 6,962,500 discloses another kind of ejecting mechanism, when the card in the electrical connector, the ejecting mechanism is not beyond the electrical connector except a knob. When ejecting the card, the user need to press the ejecting mechanism twice. Referring to FIG. 7, an electrical card connector has an ejecting member as mentioned-above is shown. The ejecting member 6 comprises a pushing pole 610, a base plate 611, a slider 612, a connecting pole 620 and an ejecting member (not shown). When the pushing pole 610 moving, the slider 612 moves subject to the pushing pole 610 along a heart-shaped track 6110 of the base plate 611 and resists on an engaging part 6200 of the connecting pole 620 to ejecting the card. However, when a card is not inserted into the card connector, the pushing pole 610 still has a possibility to beyond the card connector. Accordingly, the ejecting mechanism is easily broken when an improper force working on the part beyond the electrical card connector.
Hence, it is desirable to have an improved card connector to overcome the above-mentioned disadvantages of the prior art.
BRIEF SUMMARY OF THE INVENTION

DETAILED DESCRIPTION OF THE INVENTION
Reference will now be made to the drawing figures to describe the present invention in detail.
Referring to FIG. 1 to FIG. 4, an electrical card connector 1 in accordance with the present invention comprises a shield 2, a guiding member 3, an insulaitive housing 4 and an ejecting mechanism 5. The shield 2, made of metallic plate, has one end mounted on the insulative housing 4 and another end defining an inserting opening 10 provided for a card inserting. The guiding member 3 is placed in the shield 2 for guiding the card till a right position. In present embodiment, the electrical card connector 1 electrically connects with a Flexible Printed Circuit (FPC) 8, and is mounted on a base plate 9. The FPC 8 electrically connects to a board to board connector 20 at the end opposite to the electrical card connector 1.
The insulative housing comprises a main body 41 and a contacting portion 42 extending from the main body 41. A plurality of terminals (not labeled) are located in the main body 41 and the contacting portion 42 of the insulative housing for electrically connecting with the card.
The ejecting mechanism 5 comprises a lever mechanism 51 and a pushing mechanism 52 assembled with the lever mechanism 51. The ejecting mechanism 5 is assembled on a lateral side of the shield 2 by a retaining frame 30 locking with the shield 2. The lever mechanism 51 comprises a connecting pole 511, an ejecting member 513 and a lever member 512 connecting the connecting pole 511 and the ejecting member 513. The pushing mechanism comprises a base 521, a slider 522, a pushing bar 523, a spring member 524 and a stopping plate 525. The connecting pole 511 is sandwiched by the pushing bar 523 and the stopping plate 525.
The base 521 and the pushing bar 523, respectively, is configured of strip and are matched with each other. The base 521 defines a heart-shaped track 5211 thereon. The heart-shaped track comprises two straight slots with different length, two slant slots, respectively, extending from the straight and communicating with each other, and an incline slot communicating two straight slots opposite to the slant slots. We name four positions of the track as A, B, C and D. The position C is an original position of the longer straight slot; the position D is an end of the longer straight slot, the position A is the place of two slant slots joining; the position B is an end of a short straight slot. The pushing bar 523 comprises post 5231 and a knob 5232 opposite to the post 5231. The spring member 524 is mounted on the post 5231. The pushing bar 523 defines a receiving slot 5233, and the slider 522 is partially and movably received in the receiving slot 5233. The slider 522 forms a rib 5221 movably received in the heart track 5211 of the base 521.
The pushing bar 523 forms a stopping portion 5234 at a lateral side thereof. The stopping plate 525 comprises a panel (not labeled) and a beam 5251 extending slantly from the panel, and the beam defines a cutout (not labeled). During assembled, the stopping plate 525 is placed adjacent to the pushing bar 523 with the beam 5251 attached the pushing bar 523, and the cutout allows a part of the slider 522 to pass through. After assembled, the beam 5251 resists the stopping portion 5234.
Referring to FIG. 3, FIG. 5 and FIG. 6, when the card is not inserted in to the inserting opening 10 of the electrical card connector 1, only the knob 5232 of the pushing bar 523 is beyond the electrical card connector 1 provided for user to pressing. The rib 5221 of slider 522 is on the A position, and the beam 5251 of the stopping plate 525 resists on the stopping portion 5234 of the pushing bar 523. Thereby, even though the user presses the knob 5232, the pushing bar 523 can not move along the front-to-back direction cause of the beam 5251 resisting on the stopping plate 525. Accordingly, the pushing bar 523 keeps itself not beyond the electrical card connector 1 except knob 5232. The rib 5221 of slider 522 is at the D position.
When the card is inserted into the inserting opening 10 of the electrical card connector 1 along the front-to-back direction, the card pushing the ejecting member 513, and then the ejecting member 513 pushing the connecting pole 511 through the lever member 512, the connecting pole 511 moves along a direction opposite to the front-to-back direction till the connecting pole 511 engaging with the stopping plate 525 to separate the beam 5251 from the stopping portion 5234 of the pushing bar 523. The pushing bar 523 is still not beyond the electrical card connector 1 except knob 5232. When the card is inserted to a right position, the rib 5221 of the slider 522 moves from the D position to the A position.
When ejecting the card from the electrical card connector 1, the user presses the knob 5232, the pushing bar 523 moves along the front-to-back direction. The rib 5221 of the slider moves from the A position to the B position, and then to the C position cause of the resilient force of the spring member 524 and as the rib 5221 of the slider 522 moves from the B position to the C position, the slider 522 passed through the cutout of the stop plate 525. Now, the pushing bar 523 has a long portion beyond the electrical card connector 1. The user presses the knob 5232 again, the pushing bar 523 pushing the slider 522, the slider 522 pushing the connecting pole 511 along the front-to-back direction with the rib 5221 moving from the C position to the D position, and then the connecting pole 511 pushing the ejecting member 513 through the lever member 512 to ejecting the card. The pushing bar 523 resumes to the station when the card is not inserted into the inserting opening 10. The beam 5251 of the stopping plate 525 resists the stopping portion 5234 again.
Because the existing of the stopping plate 525, when the card is not inserted into the electrical card connector 1, the pushing bar 523 is not beyond the electrical card connector 1 all the time except the knob 5232.
It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
