Stacked connection device

摘要

An electrical connection device includes a lower connector and an identical upper connector stacked on and fixed to the lower connector to form a connector stack. A metal shield, including a front shielding member and a rear shielding member, encases the connector stack and a lower face of the lower connector is exposed for being positioned on a printed circuit board. The connectors retain conductive pins having free ends downwardly extending beyond the lower face for electrically engaging the circuit board. Each connector forms a dovetailed tenon on a top face thereof and defines a complementary dovetailed mortise on an opposite bottom face. The connectors are fixed together by means of a tenon and mortise joint formed between the upper connector and the lower connector. Alternatively, a coupler may be provided to connect the upper connector to the lower connector. The coupler comprises a tenoned top face and a mortised bottom face respectively forming a tenon-and-mortise joint with the upper and lower connectors thereby fixing the upper connector to the lower connector.
