ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to a board-to-board connector assembly, and particularly to a pair of plug and receptacle connectors mating with each other.
2. The Related Art
Board-to-board connectors may be referred to U.S. Pat. Nos. 5,224,866, 5,310,357, 5,433,616, 5,393,250, 5,478,248, 5,545,051 and 5,556,286. Anyhow, an object of the invention is to provide a pair of board-to-board receptacle and plug connectors which are adapted to be reliably and securely coupled to each other.
SUMMARY OF THE INVENTION
According to an aspect of the invention, a pair of board-to-board connectors including a receptacle connector and a plug connector. The receptacle connector includes an insulative first housing having a plurality of first passageways for receiving a corresponding number of first contacts therein, respectively. Each first contact is of a resilient bellow type and the distal end thereof abuts against the butting wall of the housing for pre-loading consideration, thus controlling the contact gap for mating. The plug connector includes an insulative second housing having a plurality of second passageways for receiving a corresponding number of second contacts therein, respectively. Each second contact is of a stiff stick type and the distal end thereof abuts against the side wall for confronting the mated corresponding first contact. A pair of lateral projections are formed at either end of each housing for protecting the tails of the contacts therebetween.
Another object of the invention is to provide an extension type receptacle connector which has an increased height wherein to stabilize the longer body of the contact, a supporting block is inserted into the cavity of the housing for full engagement with the body of the contact so that the contact can be stably and reliably retained within the corresponding passageway for efficiently resisting the improper impact.
