ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a card edge connector, and particularly to a VRM (Voltage Regulate Module) connector having an ejector at an end of a housing.
2. Description of Related Art
U.S. Pat. Nos. 5,780,463 and 5,746,614 disclose a card edge connector having a pair of ejectors at two opposite ends for ejection of a daughter board inserted therein
FIG. 6
shows a conventional card edge connector
7
having an ejector
8
. The card edge connector
7
comprises an insulative housing
9
which defines a central receiving channel
90
for receiving a daughter board (not shown). Two spaced guide walls
91
are formed on each longitudinal end of the insulative housing
9
. Each of the guide walls
91
defines a pivot hole
92
for receiving a pivot spindle
81
of the ejector
8
thereby allowing the ejector
8
to be movable with respect to the guide walls
91
between a secured position and a released position. Projections
82
are formed on opposite sidewalls
80
of the ejector
8
for reliably engaging with recesses
93
defined in the guide walls
91
for retaining the ejector
7
at the secured position. A cavity
83
is defined in the ejector
8
between the sidewalls
80
for enhancing the resiliency of the ejector
8
thereby facilitating engagement between the projections
82
and the recesses
93
of the guide walls
91
.
However, when the ejector
8
is subjected to vibration or shock, the ejector
8
may resiliently deform and move from the secured position to the released position so that the daughter board in the slot
90
may disengage from the insulative housing
9
, therefore, the electrical connection between the connector
7
and the daughter board will be affected.
Therefore, an improved card edge connector is required to overcome the disadvantages of the conventional card edge connector.
SUMMARY OF THE INVENTION
Accordingly, the object of the present invention is to provide a card edge connector which can securely retain a daughter board therein.
In order to achieve the object set forth, a card edge connector for securing a daughter board therein comprises an elongated insulative housing and a pair of ejectors assembled on the insulative housing. The insulative housing comprises a central receiving channel for receiving the daughter board therein, and a pair of towers positioned at two opposite ends thereof. Each tower includes a pair of opposite guide walls defining a slot therebetween. The ejector is movably received in the slot of the tower and includes a header on a top thereof. The header comprises a locker extending toward the central receiving channel for securely retaining the daughter board in the central receiving channel, and a pair of arms extending opposite to the locker. The arms each include a respective retention protrusion for releasably locking to the guide walls.
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
