ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an electrical connector assembly, and particularly to an electrical connector assembly for electrically connecting a chipset to a printed circuit board.
2. Description of Prior Art
The trend of the computer industry is continuing toward improvement of functional abilities, miniaturization of electrical component, and convenience of assembly. A conventional chipset is connected to a printed circuit board by soldering contact tails of the chipset to the board. Since the tails of the chipset are densely arranged, the soldering procedure is inconvenient. Furthermore, if the chipset requires replacement, it cannot be easily removed from the PCB. Thus, the conventional assembly process is inadequate and does not follow the trend of the computer industry.
To overcome the problems mentioned above, some chipsets are detachably mounted to a print circuit board by mating the contacts of the chipset with the resilient terminals of a connecting component, and then attaching the connecting component to the PCB. However, when a force is exerted on the chipset, disconnection with the connecting component may occur.
SUMMARY OF THE INVENTION
Accordingly, an object of the present invention is to provide an electrical connector assembly having a fastening piece for facilitating retention of a chipset therein.
In the preferred embodiment of the present invention, an electrical connector assembly comprises a dielectric housing having a plurality of terminal receiving passageways defined between a top mating face and a bottom terminating face thereof, and connecting protrusions formed opposite sides thereof. A plurality of terminals is received in the passageways of the housing. Each terminal has a contact portion and a tail portion extending from the contact portion. A fastening piece is attached to the housing, and includes a body and legs extending substantially perpendicular from opposite ends of the body. Each leg defines a mating groove on an inner face thereof for mating with the corresponding connecting protrusion of the housing. When the fastening piece is mounted to the housing, a chipset is securely sandwiched between the fastening piece and the housing, and when the fastening piece is removed from the housing, the chipset can be easily detached from the housing.
