ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a socket connector having an ejector for easily removing an integrated circuit (IC) module received in the socket connector.
2. Description of the Prior Art
A conventional socket connector for carrying a land grid array (LGA) IC module usually defines restricting fingers for resiliently retaining the IC module in the socket connector. Examples of such socket connectors are disclosed in U.S. Pat. Nos. 6,146,152, 6,186,797, 6,164,978, 6,203,331 and 6,179,624.
FIG. 6
shows a conventional socket connector
6
as disclosed in U.S. Pat. No. 6,146,152. The socket connector
6
provides a recessed area
63
to receive an LGA IC module
7
thereon. The recessed area
63
defines a plurality of passageways
60
, and each passageway
60
accommodates a conductive contact
8
therein. The socket connector
6
has a pair of push fingers
611
on two adjacent sides
61
thereof respectively. Each push finger
611
comprises a spring portion
6111
extending from the side
61
, and a restricting portion
6112
extending from the distal end of the spring portion
6111
and protruding into a space above the recessed area
63
. Thus, the restricting portion
6112
projects beyond an inner edge of the side
61
. When the IC module
7
is received on the recessed area
63
, the push fingers
611
retain the IC module
7
in the correct position. However, if the IC module
7
is required to be removed from the recessed area
63
for replacement or maintenance, this is difficult because of the confined spaces in and around the socket connector
6
. A conventional method is to pull the push fingers
611
away from the recessed area
63
to release the IC module
7
. However, this is liable to break the push fingers
611
and damage the restricting mechanism of the socket connector
6
.
Hence, a new socket connector which overcomes the above-described disadvantages is desired.
SUMMARY OF THE INVENTION
Accordingly, a primary object of the present invention is to provide a socket connector having an ejector for easily removing an IC module received in the socket connector.
In order to achieve the above mentioned object, a socket connector in accordance with a preferred embodiment of the present invention comprises an insulative housing mounted on a printed circuit board (PCB), a plurality of contacts received in the housing, and an ejector pivotally jointed with the housing. The ejector comprises a pivot axle pivotally received in the housing, a lever extending from a middle portion of the pivot axle, a transverse pressing button extending from a distal end of the lever perpendicularly, and an ejecting portion extending from the middle portion of the axle in a direction substantially perpendicular to the lever. When the IC module is received in the housing, the ejecting portion of the ejector is suppressed under the IC module. When the IC module is required to be removed from the housing, the pressing button of the ejector is pressed down and, as a result, the ejecting portion rotates about the pivot axle and finally pushes the IC module upwardly. Thus, the IC module is removed from the housing easily.
Other objects, advantages and novel features of the present invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings, in which:
