## Abstract

When a memory card is inserted into a housing of a memory card connector, a terminal of the memory card contacts a contact terminal so formed as to extend in an inserting direction in the housing. When the memory card reaches a mounting position, a locking mechanism locks the memory card at the mounting position by engaging with a side recess of the memory card.

## Claims

### Claim 1

A memory card connector comprising:
a housing forming an insertion part into which a memory card is inserted;
a contact terminal formed long in an inserting direction in said housing so as to contact a terminal of said memory card;
a locking mechanism locking said memory card at a predetermined mounting position by engaging with a side recess of said memory card when said memory card is inserted into said insertion part and reaches a vicinity of said mounting positions said locking mechanism including a locking member changing position to a locking position so as to engage with said side recess of said memory card when said memory card is inserted into said insertion part and reaches the vicinity of said mounting position;
a sliding member supporting said locking member so as to cause said locking member to engage with said side recess of said memory card, and including a contact portion contacting on an inserting end of said memory card so as to be pressed in the inserting direction,
an engaging portion contacting on a contact surface of said side recess by so inclining with respect to said contact surface as to bite thereinto, and
a plate spring portion causing said engaging portion to contact on said contact surface of said side recess by a pressing force.

### Claim 2 (depends on 1)

The memory card connector as claimed in claim 1, wherein said housing comprises an unlocking guide portion causing said locking member to change position to an unlocking position according to a sliding movement of said sliding member by said memory card moving further in the inserting direction from said mounting position.
