Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a type of electric connector assembly, and more particularly to an electric connector assembly which is attached to two circuit boards and which engages by rotating and inserting a predetermined range. .

[0002]

2. Description of the Related Art In a notebook, a circuit board for a specific purpose is rotated by a predetermined angle and then abutted on a main board, so that a board-to-board type electrical connector assembly that can be inserted and connected by rotation is provided. is necessary.
However, since the conventional board-to-board type electrical connector assembly can generally only abut in the vertical direction, if an attempt is made to insert the connection by rotation, the insertion connection end of the electric connector will be generated during the engagement. Will interfere with each other and it will not be possible to smoothly insert and connect.

Another conventional technique uses a flexible printed circuit board to connect a circuit board for a specific purpose to a main board. However, since the method of connecting via the flexible printed circuit board is used for the case where the rotation angle of the circuit board is small, the contact pressure of the flexible printed circuit board is not large in the insertion connection with a large rotation angle. Since it is sufficient, it is easy to be pulled out or damaged.

Due to the rapid development of computers, the manufacture and installation of notebooks requires pivoting insert connections with large pivoting angles for board-to-board electrical connector assemblies, and the present invention addresses this need. Accordingly, an improved design was made to the conventional electrical connector assembly.
