Connector and connector groove

A memory card connector, which is electrically connected to a memory card by inserting the memory card having surface contact terminals arranged at an end part, the memory card connector comprising:

• a housing comprising a card holding part of an approximately thin rectangular parallelepiped shape including a housing space and a card insertion port, through which the memory card is inserted, the memory card being held in the housing space so that the surface contact terminals are located at a near position from the card insertion port;
• and
• a plurality of cantilever contacts having contact points being positioned in the card holding part, the contact points to be contacted with the surface contact terminals of the memory card, each of the cantilever contacts having a lead part, to be solder-bonded to an opposite side to the contact points, extending outside from a stopping wall opposite to the card insertion port;
• wherein a plurality of first press-fitting grooves for holding first fixed parts near free ends part having the contact points, are formed in a bottom surface of the card holding part,
• wherein a plurality of second press-fitting grooves for holding second fixed parts near the lead parts, are formed in a bottom face of the housing that opposes to the bottom face of the card holding part,
• each of the first press-fitting grooves has upper-face opened recess parts and lower-face opened recess parts, which are continuous with the first press-fitting groove, formed therein in an alternating manner, and each of the first press-fitting groove is formed in an intermittent manner by the upper-face opened recess parts and lower-face opened recess parts.

A press-fitting groove, in which a fixed part of a cantilever contact is press-fitted, wherein:

• the press-fitting groove is defined by two pairs of opposing walls,
• a first pair of walls extend continuously in parallel along a longitudinal direction;
• a second pair of walls extend discontinuously in parallel along the longitudinal directions, the first and second pairs of walls being adjoining at edges thereof;
• when the first pair of walls are disposed separately and oppositely with a predetermined distance in a lateral direction, the second pair of walls are disposed separately and oppositely with another predetermined distance in a vertical direction, the second pair of walls comprising a first wall and a second wall;
• the first and second walls extend in a longitudinal direction in a discontinuous manner and do not overlap in a plan view.
