Abstract
A memory card is disclosed which has a card body (2) having a concavity (9) formed at the forward end thereof in the inserting direction and in which terminals (5) are disposed and projections (10) are formed between the terminals (5) to prevent the terminals (5) from being touched or accessed from outside. A receptacle for the memory card is also disclosed. The memory card has a simple structure designed to positively protect the terminals and easily let out dust or the like from inside, thereby permitting to assure a positive connection with the receptacle.
Claims4
A system having a memory card and a memory card receptacle for writing or reading information signals to/from said memory card;
- said memory card comprising:
- a card body incorporating at least one memory chip, the card body having a top, a forward and a rearward end;
- the top of the card body having a concavity open at the forward end;
- and
- a plurality of terminals disposed side by side in the concavity in the inserting direction of the card body;
- and
- a projection formed in at least a part of a space between two successive terminals disposed in the concavity to protect the terminals from undesired outside contact;
- the concavity having an inner wall inclined to the inserting direction of the card body;
- said memory card receptacle comprising:
- a body;
- a receiving concavity open at an end of the body of said memory card receptacle and in which said memory card is introduced;
- a plurality of terminals to be connected to said plurality of terminals of said memory card respectively;
- and
- a plurality of projections;
- wherein said plurality of projections are slidable on said plurality of terminals of said memory card respectively before said plurality of terminals of said memory card receptacle are connected to said plurality of terminals of said memory card.
A memory card receptacle comprising:
- a body;
- a receiving concavity open at an end of the body of said memory card receptacle and in which a memory card is introduced, said memory card having a memory card body, a concavity formed in the card body having an inclined wall, and electrical contacts disposed in the concavity;
- a plurality of terminals to be connected to the contacts of the memory card respectively, and the tips of said plurality of contacts being disposed inside said receiving concavity;
- and
- a plurality of projections provided ahead of the plurality of terminals of said memory card receptacle and formed so as to slide on the contacts of the memory card respectively before said plurality of terminals of said memory card receptacle are connected to said contacts of said memory card so that the projections remove foreign materials from inside the concavity of the memory card over the inclined wall of the concavity of the memory card.
