Abstract: A memory card connector includes an insulating housing defining conductive terminal grooves and a switch terminal groove. A metallic shell coupling with the insulating housing to form a card cavity therebetween has a top section and two side sections. The front of a top surface of one side section extends and inclines to the front of the top section to form an anti-mismating portion connecting with the front of the top section to form an inclined corner at the front of the metallic shell. One side section extends rearward to form a touching portion protruding toward the inner of the card cavity. Conductive terminals received in the conductive terminal grooves have a base portion, a soldering portion and a contacting portion. A switch terminal assembled in the switch terminal groove has a main body extending rearward to form a resilient arm received in the card cavity. The resilient arm defines a contacting projection facing the touching portion and a pressing portion facing the inner of the card cavity.

Abstract: A memory card connector includes an insulating housing having a top wall and two sidewalls and defining conductive terminal grooves and a switch terminal groove. One sidewall extends upward and then extends toward the other sidewall to define an anti-mismating portion having a transverse portion above the top wall and a vertical portion connecting with the transverse portion and the sidewall. A metallic shell coupling with the insulating housing to form a card cavity has two side sections. One side section extends rearward to form a touching portion. Conductive terminals received in the conductive terminal grooves have a base portion, a soldering portion and a contacting portion. A switch terminal assembled in the switch terminal groove has a main body extending rearward to form a resilient arm received in the card cavity. The resilient arm defines a contacting projection facing the touching portion and a pressing portion facing the inner of the card cavity.

Abstract: A memory card connector includes an insulating housing defining conductive terminal grooves and two locating grooves at a sidewall thereof. A shelter shell coupling with the insulating housing to form a card cavity has a top section and two side sections. A front surface of the top section extends frontward and then extends downward to form two anti-mismating portions adjacent to the two side sections. The two anti-mismating portions have different width and vertical length. Conductive terminals are fixed in the conductive terminal grooves and soldered to a printed circuit board for electrically engaging with corresponding contacts of a memory card inserted into the card cavity. And a pair of switch terminals mounted in the locating grooves and soldered to the printed circuit board. One switch terminal is pressed outward by the memory card fully inserted into the card cavity, which causes the two switch terminals to contact with each other for grounding.
