Lower profile card edge connector

A card edge connector, comprising:

• an insulative housing defining a central slot extending along a longitudinal direction, a first wall and a second wall located on the opposite sides of the central slot and a rear wall connecting the first and second walls;
• a plurality of first terminals retained in the first wall of the insulative housing and each including a first contacting arm extending into the central slot and a first soldering portion extending outside of the insulative housing;
• and
• a plurality of second terminals retained in the second wall of the insulative housing and each including a second contacting arm extending into the central slot and a second soldering portion extending outside of the insulative housing in an opposite direction of the first soldering portion;
• wherein
• the first and second soldering portions are located in a same mounting plane which is higher than the bottom face of the first wall.

A card edge connector assembly comprising:

• a printed circuit board defining a through opening extending through opposite upper and lower surfaces of said printed circuit board in a vertical direction and circumferentially bounded by corresponding edge sections of the printed circuit board essentially composed of opposite front and rear edge sections and opposite side edge sections;
• an elongated insulative housing defining a horizontal card receiving slot located between opposite upper and lower walls in a longitudinal direction perpendicular to said vertical direction;
• a plurality of upper contacts disposed in the upper wall with resilient upper contacting sections extending into the card receiving slot and upper tail sections soldered to the printed circuit board around the rear edge sections;
• and
• a plurality of lower contacts disposed in the lower wall with resilient lower contacting sections extending into the card receiving slot and lower tail sections soldered to the printed circuit board around the front edge sections;
• wherein
• a lower portion of the lower wall of the housing being a fitting portion, is disposed in the through opening.
