ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an audio jack, and particularly to an audio jack having a side mount grounding terminal for engaging with an audio plug.
2. Description of Related Art
U.S. Pat. No. 6,056,602 discloses a conventional audio jack
9
with a top loading grounding terminal
92
shown in FIG.
6
. The grounding terminal
92
has a center portion
923
, an elongate portion
920
inwardly extending from an upper edge of the center portion
923
, and a solder pad
921
outwardly extending from a lower edge of the center portion
923
. A stepped engaging portion
922
ends from the elongate portion
920
. The grounding terminal
92
is adapted to be mounted to a body
90
with the center portion
923
received in a first fixing groove
902
and the elongate portion
920
received in a second fixing groove
903
. The engaging portion
922
of the grounding terminal
92
extends into an opening
904
in a top wall
900
of the body
90
for contacting a corresponding portion of an inserted audio plug (not shown) for grounding. The opening
904
is defined at the junction of a front wall
901
and a sleeve
91
projecting from the front wall
901
. Therefore, the opening
904
reduces the strength of the front wall
901
and the sleeve
91
. When the audio plug is frequently inserted into or pulled out of the audio jack, the sleeve
91
and the body
90
must bear certain stress. Accordingly the sleeve
91
is easy to break after repeated insertions of the audio plug or especially when a vertical force is applied thereto due to the position of the opening
904
.
Therefore, an audio jack having a side mount grounding terminal is desired to increase the strength of a sleeve thereof.
SUMMARY OF THE INVENTION
Accordingly, the object of the present invention is to provide an audio jack for receiving an audio plug, the audio jack having a side mount grounding terminal for increasing the strength of a sleeve thereof.
In order to achieve the object set forth, an audio jack of the present invention comprises an insulative casing inside which a plurality of conductive terminals and a grounding terminal are disposed. The casing has a front face, a rear face, a pair of opposite side faces, and a bottom wall defining a recess in an inner side thereof. An interior space is defined in the casing. The front face has a sleeve formed thereon and defined a channel in communication with the interior space for receiving a pin of a mating plug for audio signals transmission. One side face of the casing defines a window communicated with the interior space via the recess and a slit communicated with the window. The grounding terminal comprises a horizontal plate portion received in the slit, an upwardly extending contact portion extending through the window and projecting into the interior space through the recess, and a solder pad for being mounted on a printed circuit board.
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description of the preferred embodiment when taken in conjunction with the accompanying drawings.
