ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to the art of electrical connectors, and more particularly to a land grid array connector assembly having a fastening device for securing a central processing unit (CPU) therein.
2. Description of the Prior Art
A conventional land grid array connector assembly
6
, as shown in
FIG. 8
, commonly includes a fastening device
60
and a socket
61
received in the device
60
. The fastening device
60
comprises a quadrate frame
63
, a lever
62
and a metal clip
64
respectively mounted to opposite sides of the frame
63
. The frame defines a pair of locating slots
66
at one side thereof and a pair of guiding grooves
65
at another opposite side thereof. Each guiding groove
65
has a first inner wall
651
and a second inner wall
652
. The lever
62
has a pair of locating portions
623
pivotally positioned in locating slots
66
of the frame
63
, a driving portion
621
defined between the locating portions
623
, and a handling portion
622
bending vertically from one of the locating portions
623
. The clip
64
has a pair of securing portion
641
movably received in the guiding grooves
65
of the frame
63
and a driving hook
644
defined at a free end thereof.
In use, the clip
64
is firstly set up perpendicular to the frame
63
with the securing portion
641
pressing close to the first inner walls
651
of the guiding grooves
65
, a CPU
7
, together with a copper plate
8
which functions as a heat dissipation device, is assembled on the socket
61
. Then, the clip
64
is rotated to a parallel position and abuts against the copper plate
8
. However, as can be seen from
FIG. 9
, during the rotation of the clip
64
, the clip
64
may simultaneously move along the guiding grooves
65
towards the second inner wall
652
which leads to the driving hook
644
of the clip
64
extending beyond its correct position. As a result, when rotating the handling portion
622
of the lever
62
, the driving portion
621
of the lever
62
cannot slide into the driving hook
644
of the clip
64
and drive it, which leads to the clip
64
can not reach its final pressing position. Thus, the clip
64
fails to locate the CPU
7
and the copper plate
8
securely.
SUMMARY OF THE INVENTION
Accordingly, an object of the present invention is to provide a land grid array connector assembly having a fastening device for retaining a central processing unit (CPU) securely in the connector assembly.
Another object of the present invention is to provide a fastening device for a land grid array socket to fasten a CPU in the land grid array socket.
In order to achieve the objects set forth, a land grid array connector assembly in accordance with the present invention includes a socket and a fastening device surrounding the socket. The fastening device comprises a frame having a first side and a second side opposite to the first side, a lever pivotally mounted to the first side of the frame, and a metal clip movably mounted to the second side of the frame.
The frame includes a pair of locating slots defined at opposite ends of the first side and a pair of locating grooves defined at opposite ends of the second side, each locating groove has a horizontal portion and an arced portion connected with the horizontal portion. The lever has a pair of locating portions received in the locating slots, a driving portions defined between the locating portions, and a handling portion bending vertically from one of the locating portions. The clip has a pair of acting portions respectively received in the locating grooves and a driving hook defined at a free end thereof. The acting portions of the clip can only rotate in the arced portions of the locating grooves when the clip rotates from a vertical position to a horizontal position and can only slide in the horizontal portions of the locating grooves when the driving portion of the lever drives the driving hook of the clip.
