ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a ZIF socket, and particularly to a ZIF socket having enough space for manipulating an actuating rod thereof.
2. Description of Related Art
Conventionally, a low-profile ZIF socket receiving an integrated circuit (IC) chip has small space for handling. Referring to FIG.
3
and
FIG. 4
, a conventional ZIF socket
5
includes a base
6
, a sliding cover
7
and an actuating rod
7
. The base
6
comprises a plurality of through holes
60
for receiving corresponding contacts
50
, a lower receiving channel
61
and a concavity
62
in front of the lower receiving channel
61
. The sliding cover
7
is assembled on the base
6
and comprises a plurality of receiving holes
70
for receiving corresponding pins of an integrated circuit chip
52
. The sliding cover
7
includes a tailboard
71
in a rear end thereof. The tailboard
71
comprises a mounting section
74
and a second transverse receiving channel
73
in a middle of the mounting section
74
. The actuating rod
8
is substantially an L-shaped rod and comprises a straight handle
80
and a driving arm
81
perpendicular to the handle
80
. The driving arm
81
is retained in the lower receiving channel
61
by the mounting section
74
and includes a curved arm
82
extending forwardly in a middle thereof. The curved arm
82
is received in the concavity
62
of the base
6
and drives the sliding cover
7
to move longitudinally along the base
6
. When the handle
80
moves between a closed position and an open position, the curved arm
82
rotates in the concavity
62
and drives the sliding cover
7
to move longitudinally along the base
6
thereby moving the pins of the chip
9
to electrically connect with the contacts
50
.
However, when the handle
80
is in the closed position, i.e., in a horizontal position, a distance between the handle
80
and a mating printed circuit board
51
is too small to hold and the ZIF socket
5
is inconvenient to handle.
Hence, an improved ZIF socket with enough space for handling is required to overcome the disadvantages of the conventional ZIF socket.
SUMMARY OF THE INVENTION
Accordingly, the object of the present invention is to provide a ZIF socket with enough space for handling.
In order to achieve the object set forth, a ZIF socket with a plurality of contacts comprises a base, a sliding cover and an actuating rod. The base includes a baseboard and a mounting portion in a rear end thereof. The baseboard comprises a plurality of through holes for receiving the contacts. The mounting portion comprises a first transverse receiving channel. The sliding cover is assembled on the base and comprises a cover board and a tailboard in a rear end thereof. The cover board includes a pair of side walls extending from each transverse edge thereof. The tailboard comprises a second transverse receiving channel in middle thereof. The actuating rod includes a handle and a driving arm extending perpendicularly from an end of the handle. The driving arm comprises a pair of coaxial pivots received in the receiving channel and a curved arm extending forwardly between the pivots. The curved arm is received in the upper receiving channel and rotates to drive the sliding cover to move longitudinally along the base. The handle has a straight rod and a grasping arm parallel to the straight rod with an upswept distance. The grasp arm includes a remainder portion with removal of a lower portion thereof to afford large space for handling.
