Electrical card connector with improved card restriction structure

An electrical card connector for insertion of a first card and a second card which is wider than the first card, comprising:

• an insulative housing defining a front mating face and a card receiving space recessed from the front mating face for receiving the first and the second cards;
• a plurality of contacts with contact portions extending into the card receiving space for mating with the first and the second cards;
• a pair of elastic springs each including a coiled portion and a pair of first and second abutting portions extending from opposite ends of the coiled portion;
• and
• a rotatable card restriction member including a main body upwardly extending into the card receiving space and a pair of pivots extending from lateral sides of the main body to be received through the coiled portions, the first and the second abutting portions abutting against the main body and the insulative housing, respectively;
• and wherein the main body comprises an inclined guiding surface and a raised portion protruding upwardly beyond the guiding surface, under a condition that the first card is sidewardly restricted by the raised portion with insertion of the first card into the card receiving space, and the second card abuts against an upper surface of the raised portion with insertion of the second card into the card receiving space.

An electrical card connector assembly for use with first and second cards, comprising:

• an insulative housing defining a front mating face and a card receiving space behind the front mating face for receiving at least first and second cards mutually exclusively;
• a plurality of contacts disposed within the housing with contacting sections extending into the card receiving space;
• an up-and-down moveable card restriction member positioned in the card receiving space adjacent to the front mating face, some of said contacts located under said card restriction member, said card restriction member including a main body defining a plurality of juxtaposed slots in a front-to-back direction and in alignment with the corresponding ones of said some of the contacts in a vertical direction;
• said main body defining an upper abutment face at an upper level and a lower abutment face at the lower level, respectively, wherein
• the upper abutment face supports the first card during insertion of the first card;
• the second abutment face supports the second card during insertion of the second card.
