Patent ID: 8202125

Claim:
A card connector comprising: a first inserting slot for insertion of a first memory card with a plurality of first terminals extending thereinto for mating with the first memory card; a second inserting slot for insertion of a second memory card with a plurality of second terminals extending thereinto for mating with the second memory card; and a partition wall located between the first and second inserting slots for separating the first inserting slot and the second inserting slot; wherein the partition wall has at least one spring arm integrally extending therefrom and located between the first and second inserting slots, when one of the first and second memory cards is inserted into the corresponding one of the first and second inserting slots, the spring arm protrudes into the other one of the first and second inserting slots so as to prevent the other one of the first and second memory cards from being inserted into the other one of the first and second inserting slot, wherein the spring arm extends in a cantilevered manner, the spring arm has a fixed end connecting to the partition wall and a stopper formed at a free end opposite to the fixed end for protruding into the first or second inserting slots, wherein when there is no memory card inserted into the card connector, the stopper protrudes into the first inserting slot and does not protrudes into the second inserting slot, wherein when the first memory card is inserted into the first inserting slot, the first memory card pushes the stopper protruding into the second inserting slot so as to prevent the second memory card from being inserted into the second inserting slot, when the second memory card is inserted into the second inserting slot, the stopper having protruded into the first inserting slot keeps still and is enforced in its original position by the second memory card so as to prevent the first memory card from being inserted into the first inserting slot, wherein the stopper has a projection protruding into the first inserting slot and defining an inclined surface extending obliquely relative to the partition wall.
