ABSTRACT:
A short-circuit-proof card connector is composed of a shell and at least two (first and second) terminal groups. The shell includes an opening, at least two receiving spaces for receiving a first card and a second card respectively, two first guiding faces formed at bilateral sides of the first receiving space, and two second guiding faces formed at bilateral sides of the second receiving space. The second terminal group close to the opening has a power terminal and a grounded terminal. A first interval is defined between the first and second guiding faces close to the power terminal. A second interval is defined between the first and second guiding faces close to the grounded terminal. The first interval is smaller than the second interval such that an electrically conductive surface of the first card does not touch the power terminal to avoid short circuit while the first card is inserted.
