ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a jack connector, and particularly to an audio jack connector which has contacts with desirable resiliency.
2. Brief Description of the Prior Art
U.S. Pat. No. 5,092,795 discloses a conventional connector
6
(shown in
FIG. 6
) which comprises a dielectric housing
101
, a metallic grounding shroud
500
enclosing the housing
101
, a conductive grounding contact
200
, a first contact
300
and a second contact
400
.
The housing
101
includes a case
103
for receiving the contacts
200
,
300
and
400
and a sleeve
102
forwardly projecting from the case
103
through which a complementary plug (not shown) is inserted. The U-shaped grounding shroud
500
forms a grounding leg
501
for grounding the complementary plug (not shown) and a pair of soldering fingers
502
outwardly extending. The grounding terminal
200
has a flat base
201
, a grounding arm
203
upwardly depending from the base
201
and a soldering finger
202
rearwardly and horizontally extending from a middle rear edge of the base
201
. The first contact
300
includes a flat base
301
, a soldering finger
302
depending outwardly from a bottom edge of the base
301
, and a longitudinal engaging arm
303
continuing forwardly from the base
301
. The second contact
400
has an elongated base
401
, a soldering finger
402
outwardly depending from a bottom edge of the base
401
, and a longitudinal engaging arm
403
depending rearwardly from the base
401
. The engaging arm
303
of the first contact
300
and the engaging arm
403
of the second contact
400
are laterally spaced from each other and cooperate for mating with the inserted complementary plug (not shown).
In assembly, the first contact
300
and the second contact
400
are respectively located at right and left interior sides of the case
103
of the housing
101
. The grounding terminal
200
is forwardly inserted from a rear end of the housing
101
. The shroud
500
is then engaged with the outside of the case
103
.
As can be seen, since the first contact
300
and the second contact
400
engage with the inserted plug (not shown) at lateral sides of the plug (not shown), the conventional connector
6
has great transverse dimension. Moreover, the engaging beams
303
and
403
are substantially linear so that they have less rigidities thereof, unsuitable for reliable engagement with the inserted plug (not shown).
Hence, an improved electrical connector is required to overcome the disadvantages of the prior art.
BRIEF SUMMARY OF THE INVENTION
An object of the present invention is to provide a connector with contacts which possesses desirable resiliency.
To achieve the above-mentioned object, a connector provided includes a housing with a rectangular case, a dielectric holding member enclosed by the case, a first contact and a pair of second contacts. The case defines two slots, in each of two opposite sides thereof. The holding member has an irregular body, a pair of grooves in lateral sides of the body, and a cutout in a rear end of the body. A pair of latches and a pair of blocks extend outwardly from the body.
The first contact has a base and a connecting plate connecting a soldering plate with the base, and a pair of engaging plates extending upwardly from-the base. The engaging plate is configured to mating with an inserted plug.
Each second contact has a beam, a soldering pad projecting outwardly from a bottom end of the beam, and an engaging beam extending inwardly from a top end of the beam. A pair of shoulders projects from lateral sides of the beam. The engaging beam has a stamped engaging projection at a free end thereof for reliable contacting a mated plug. The shoulders engage with the holding member so that a cantilever is formed by a part of the beam above the shoulders providing desired resiliency thereof.
In assembly, the first contact is retained on the holding member by means of the connecting plate thereof mating with the cutout. The second contacts are retained in the holding member by means of the beam fitting in the grooves and the pair of shoulders downwardly pressing against the body of the holding member. Then, the housing downwardly encloses the holding member by the latches and the blocks fitting with the slots thereof thereby securing the first and the second contacts therebetween.
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.
