Memory card connector with card ejection mechanism

#The present invention generally relates to a memory card connector, more particularly to a memory card connector with card ejection mechanism.

#A prior memory card connector is disclosed in U.S. Pat. No. 6,508,402 issued on Jan. 21, 2003, which includes an insulating housing having a stopper, a plurality of terminals fixed in the insulating housing, a cover engaging with the insulating housing to form a holding space for holding a memory card and an ejection mechanism ejecting the memory card from the holding space. The ejection mechanism has a slider and a spring. When the ejection mechanism is assembled in the insulating housing, the spring is compressed between the insulating housing and the slider, and the slider is pushed to press the stopper by resilient fore of the spring.

#It is obvious that the spring is deformed under the compression of the insulating housing and the slider in the assembly. The deformed spring will bias the slider and make the slider rotate upward around its end that presses the stopper, hence the slider is often ejected from the insulating housing during assembling thereof. Therefore the assembly of the prior memory card connector is troublesome, which is hindrance to increase production efficiency.

#The present invention will be apparent to those skilled in the art by reading the following description of embodiment thereof, with reference to the attached drawings, in which:

#FIG. 1 is a perspective view of a memory card connector according to the present invention;

#FIG. 2 is an exploded, perspective view of the memory card connector shown in FIG. 1;

#With reference to FIG. 1 and FIG. 2, a memory card connector 10 according to the present invention is shown. The memory card connector 10 includes an insulating housing 100, a plurality of terminals 200 fixed on the insulating housing 100, a cover 300 which engages with the insulating housing 100 to form a holding space for holding a memory card 20 and an ejection mechanism 400 which ejects the memory card 20 from the holding space.

#The cover 300 has a top plate 310 and two side plates 320 which are bend downward from both side edges of the top plate 310 respectively, and a plurality of fixing holes 321 are formed in each side plate 320. One side plate 320 is provided with a first opening 322, and a pressing member 323 is provided at the front end thereof and extended into the first opening 322. Furthermore, a soldering leg 324 is extended from the front end of each side plate 320, which is soldered on a PCB (not shown) by means of SMT

#Along with reference to FIG. 3, the insulating housing 100 has a base plate 110 provided with a plurality of cavities 111 for fixing these terminals 200. Two side walls 120A, 120B and a rear wall 130 are extended upward from both side edges and rear edge of the base plate 110 respectively, and the side walls 120A, 120B, a rear wall 130 and the top plate 310 of the cover 300 enclose the holding space for the memory card 20 inserted therein. A stopper 140 is provided near to the side wall 120A at the front end of the base plate 110. A rib 112 is formed on the base plate 110 and extended parallel with the side walls 120A to form a sliding slot 113 therebewteen. The sliding slot 113 leads the ejection mechanism 400 to slide therein in the direction of insertion and ejection of the memory card 20.
