Edge card connector and an assembly of the edge card connector with an inserted card

An electrical connector assembly comprising:

• a card having a wedge formed on a rear bottom surface thereof;
• and
• an electrical connector comprising:
• a dielectric housing having a head section and a bottom plate extending rearwardly from a lower portion of the head section, the head section defining a receiving slot to divide the head section into an upper wall and a lower wall;
• and
• a plurality of contacts retained in the head section with engaging portions extending downwardly into the receiving slot for electrically contacting with the card;
• wherein the lower wall of the head section defines an inclined plane along the insertion direction of the card into the receiving slot and opposite to the engaging portions of the contacts, the inclined plane cooperating with the wedge to maintain the card constantly parallel to the bottom plate of the housing during the insertion of the card into the connector.

An electrical connector assembly comprising:

• an edge card connector comprising:
• a dielectric housing having a head section, a bottom plate extending rearwardly from a lower portion of the head section and a pair of guiding arms upwardly projecting from opposite side edges of the bottom plate;
• a plurality of contacts retained in the head section;
• and
• a pair of cards disposed on the bottom plate and arranged in a side-by-side manner between the guiding arms, the cards having mating portions electrically contacting with the contacts.

An electrical connector assembly comprising:

• an insulative housing having on a front portion a head section defining a receiving slot extending in a first direction along a longitudinal dimension of the housing and exposed to an exterior in a second direction perpendicular to said first direction;
• one row of contacts located by one side of said receiving slot;
• a bottom plate extending from the head section in said second direction;
• an electronic card defining a narrowed front region adapted to be received in said receiving slot, a plurality of conductive pads located on said front region for mechanical and electrical engagement with the corresponding contacts, respectively;
• and
• tapered mechanism formed on a rear portion of at least one of said housing and said electronic card to have the electronic card move relative to the housing in a third direction toward the contacts when the card is inserted into the receiving slot along said second direction;
• said first direction, said second direction and said third direction being perpendicular to one another;
• wherein
• most portions of the card are exposed outside the head section and supported by the bottom plate.
