A card edge connector, comprising:
- an insulating housing, the insulating housing being formed as an elongated shape extending along a longitudinal direction, the insulating housing having a top surface and a bottom surface which define an up-down direction, the insulating housing having a card edge inserting groove on the top surface along the longitudinal direction, the card edge inserting groove separating the insulating housing into a first wall body and a second wall body, a direction that the first wall body and the second wall body face each other defining a transversal direction, a direction that each of the first wall body and the second wall body faces the card edge inserting groove being an inner direction, and a direction that each of the first wall body and the second wall body is away from the card edge inserting groove being an outer direction, at least one of the first wall body and the second wall body having a plurality of terminal grooves which are arranged side by side in the longitudinal direction and each are provided in the transversal direction;
- and
- a plurality of flat plate-shaped terminals, each flat plate-shaped terminal being mounted in the corresponding terminal groove, an extending direction of a plate surface of each flat plate-shaped terminal being parallel to the transversal direction, each flat plate-shaped terminal comprising:
- a base portion positioned at a lower side of the flat plate-shaped terminal;
- a contact portion positioned above the base portion and extending into the card edge inserting groove;
- and
- an elastic arm portion positioned between the base portion the contact portion, the elastic arm portion sequentially comprising:
- a lower reverse bent section connecting the base portion, extending from the base portion toward the inner direction, reversely bending, and extending toward the outer direction and an inclined upward direction;
- an outward inclined arm section extending toward the outer direction and the inclined upward direction;
- an upper reverse bent section reversely bending and extending toward the inner direction and an inclined downward direction;
- and
- an inward inclined arm section extending toward the inner direction and the inclined downward direction,
- wherein the elastic arm portion is a two-arm configuration with a closed loop, the two-arm configuration has an inner arm and an outer arm, the inner arm and the outer arm are arranged along as overall profile of each flat plate-shaped terminal and have different profiles, the inner arm and the outer arm each have the corresponding lower reverse bent section, the corresponding outward inclined arm section, the corresponding upper reverse bent section and the corresponding inward inclined arm section which respectively correspond to the sections of the elastic arm portion.
