ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an electrical connector, and particularly to an electrical jack connector which receives a plug connector therein.
2. Description of the Prior Art
Referring to
FIG. 5
, a conventional jack connector comprises an insulative housing
100
and a first, second and third electrical contacts
101
,
102
,
103
mounted in the insulative housing
100
. The insulative housing
100
defines a pair of recesses
109
and a cavity
109
′ therein. The first and second electrical contacts
101
,
102
are substantially identical in shape and each comprises a hollow frame portion
104
, a tongue
105
upwardly and outwardly extending from a lower side of the frame portion
104
, and a tail
106
extending downwardly and opposite to the tongue
105
from the frame portion
104
. The third electrical contact
103
comprises a pair of retention plates
107
and an intermediate portion
108
therebetween. The retention plates
107
are parallel to each other. The frame portions
104
of the first and second electrical contacts
101
,
102
and the retention plates
107
of the third electrical contact
103
are retained in the grooves
109
and the cavity
109
′, respectively.
Manufacturing the above electrical contacts
101
-
103
is complicated because of difficulties in forming the frame portions
104
and bending the tongues
105
thereof. In addition, the retentions between the frame portions
104
and the housing
100
and between the retention plates
107
and the housing
100
are not reliable, particularly after the jack connector has undergone frequent mating/unmating cycles. Such faulty retentions adversely affect signal transmission between the jack connector and a complementary plug connector mating with the jack connector.
Therefore, an improved electrical connector is required to overcome the disadvantages of the prior art.
SUMMARY OF THE INVENTION
A major object of the present invention is to provide a jack connector which includes reliably retained electrical contacts having simplified structures.
An electrical jack connector of the present invention includes an insulative housing, a metallic shell substantially enclosing the insulative housing, and first, second, third and fourth electrical contacts mounted in the insulative housing. The first and second electrical contacts are similar in shape except that the first contact comprises a contact portion for engaging with an engaging portion of the third contact when a complementary plug connector is not mated with the jack connector. The first and second contacts are retained in a pair of recesses defined in a side wall of the housing. The third contact is retained by a cutout formed in a rear edge of a top wall of the housing and by a pair of grooves defined in a rear edge of a bottom wall of the housing.
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.
