ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention generally relates to a contact for an electrical connector, and particularly to a contact for a Central Processing Unit (CPU) socket connector.
2. Description of Related Art
U.S. Pat. No. 6,267,615 discloses a conventional contact for a CPU socket connector. As is shown in
FIG. 4A
, the contact
5
comprises a base
50
and a pair of arm sections
60
connected to the base
50
. The base
50
includes a body section
51
, a head section
52
extending upwardly from the body section
51
, and a soldering section
53
extending perpendicularly from a bottom edge of the body section
51
. A pair of upper projections
521
and a pair of lower projections
511
are respectively formed on opposite lateral edges of a top portion of the head portion
52
and a bottom portion of the body section
51
. The upper and lower projections
521
,
511
interferentially secure the contact
5
in the CPU socket connector.
Each arm section
60
includes an upper arm
61
extending forwardly from opposite sides of the body section
51
to the soldering portion
53
, an elbow
62
at a bottom portion of the upper arm
61
, a forearm
63
extending upwardly from the elbow
62
, a substantially planar clamp
64
at a top portion of the forearm
63
, and a palm
65
extending from a distal end of the clamp
64
toward the body section
51
. The two palms
65
and the body section
51
together define a free space
7
therebetween. The two clamps
64
define a clamping space
641
therebetween for clamping a pin
8
(see
FIG. 4B
) of the CPU socket connector.
Referring to
FIG. 4B
, the pin
8
is vertically inserted into the free space
7
and moved in direction A to the clamping space
641
. The direction A is perpendicular to the interferential direction of the upper and lower projections
521
,
511
with the CPU socket connector, whereby the contact
5
can not be retained in the CPU socket connector securely and may move with the pin
8
.
Referring to
FIG. 5
, the arm section
60
of the contact
5
is formed by a metal strip
60
′ at each side of a base strip
50
′ of a carrier strip. The pitch between two contacts
5
′ on the carrier strip is large, normally three times that of adjacent contact holes defined in the CPU socket connector. This adversely affects the efficiency of punching and assembling because one row of contact holes of the CPU socket connector must be filled up with contacts three times.
Furthermore, the contact portion (the clamp
64
′) should be gilded for improving the conductive characteristic. Because the carrier
90
and the clamp
64
′ are arranged on the same side, both of them will be immersed in electrolyte solution and the waste of aurum is great.
SUMMARY OF THE INVENTION
An object of the present invention is to provide a contact securely retained in a contact hole of a CPU socket connector.
Another object of the present invention is to provide a contact which can be efficiently inserted into the contact hole of the CPU socket connector.
A further object of the present invention is to provide a contact during gilding of which the wastage of aurum is reduced.
To fulfill the above mentioned objects, a contact for a socket connector in accordance with the present invention comprises a base and a pair of arm sections. The base has a body section adapted for being secured in the socket connector. The body section has an engaging portion extending therefrom. The pair of arm sections extends from opposite lateral sides of the base in a direction opposite to the engaging portion. The arm sections have a pair of respective planar clamps at upper ends thereof and a pair of respective palms extending from the planar clamps toward the engaging portion and away from each other.
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description of the present embodiment when taken in conjunction with the accompanying drawings.
