An edge card connector includes a rectangular parallelepiped insulating body. The insulating body includes a butting surface, a mounting surface, and a narrow and long insertion slot that is recessed from the butting surface toward the mounting surface and is opened along the length direction of the insulating body.
An electrical connector assembly for receiving the edge of a printed circuit card, the edge of the printed circuit card is provided with a conductor pad. Various circuits, especially those related to computer applications, are formed on one or both sides of a circuit board or similar substrate to form separate circuits. These separate circuits are added to computers or other electronic devices after preliminary manufacturing.
