The accompanying drawings are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification. The drawings illustrate embodiments of the invention and, together with the description, serve to explain the principles of the invention.
Reference will now be made in detail to the present preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the description to refer to the same or like parts.
Referring to
As seen along the line B-B, the insulative housing 10 has a front face 10a, a rear face 10b, a left face 10c, a right face 10d, a top face 10e and a bottom face 10f. The insulative housing 10 is provided with a first opening 102 on the front face 10 thereof, and a second opening 104 on the rear face 10b thereof. The two openings 102, 104 are communicated with each other for accommodating the central terminal 50. A third insertion slot 105 for receiving the audio terminal 40 is provided on the front face 104 of the insulative housing 10. Furthermore, the bottom surface of the insulative housing 10 has a first insertion slot 101 and a second insertion slot 103 for inserting the first conductive terminal 20 and the second conductive terminal 30, which are formed an integrated body with the insulative housing 10.
The first conductive terminal 20 is substantially a single piece element made of metal, which includes a U-shaped portion 207, a first elastic arm 201 perpendicularly connected to and extending from the U-shaped portion 207, a first base portion 205 connected to and extending from the U-shaped portion 207, a first elastic contact arm 203 extending from the first base portion 205, and a first elastic contact portion 209 extending from first elastic contact arm 203. In detail, the first elastic arm 201 is extending upward from the first U-shaped portion 207. The first elastic contact arm 203 is formed by making horizontal cutting on three sides. The first elastic contact arm 203 and the body of the first U-shaped portion 207 are connected with the first base portion 205, and the first elastic contact arm 203 extends from the first base portion 205 in the cutting direction. The first elastic contact arm 203 is connected to the first elastic contact portion 209.
The aforementioned second conductive terminal 30 includes a L-shaped latching plate 303 and a second elastic arm 301 extending upward from a top end of a L-shaped surface of the latching plate 303. Furthermore, the bottom end at another surface of the L-shaped latching plate 303 has a concave upward groove 350.
The ends of the aforementioned central terminal 50 includes a first contact portion 501 and a second contact portion 507 respectively, and the central terminal 50 further has a latching portion 503 and a joining portion 505 disposed between the first contact portion 501 and the second contact portion 507. Furthermore, the joining portion 505 has a width smaller than the latching portion 503. The surface of the latching portion 503 is engraved with a protruding pattern 504 such that the protruding pattern 504 may form a tight interferential fitting with the insulative housing 10 when the central terminal 50 is assembled inside the insulative housing 10. This prevents the central terminal 50 from rotating with respect to the insulative housing.
As shown in
The aforementioned audio terminal 40 is substantially a single piece element made of metal, which includes a third elastic arm 401, a second base portion 403, a second elastic contact arm 405, a O-shaped portion 407, and a second elastic contact portion 409. In detail, the third elastic arm 401 is perpendicularly connected to a top end of the O-shaped portion 407. The second elastic contact arm 405 is formed by making horizontal cutting on three sides. The second elastic contact arm 405 and the body of the O-shaped portion 407 are connected with the second base portion 403 and the second elastic contact arm 405 extends from the second base portion 403 in the cutting direction. The second elastic contact arm 405 is connected to the second elastic contact portion 409. In addition, the audio terminal 40 has a protruding plate 402 underneath the O-shaped portion 407 such that the protruding plate 402 may latch onto the latching hole 107 on the insulative housing 10 when the audio terminal 40 is inserted into the insulative housing 10. Hence, the audio terminal 40 is prevented from detaching from the insulative housing 10.
According to the present invention, the second conductive terminal 30 and the central terminal 50 serves as a recharging/signal transmitting unit.
When a user of the mobile communications device having the above audio jack 100 insert a first female connector of his/her charger into the audio jack, the second conductive terminal 30, central terminal 50 and the first conductive terminal 20 of the audio jack 100 form an electrical path allowing the charger to recharge the mobile communications device.
When a second female connector of his/her headset is inserted into the audio jack, the second conductive terminal 30, the central terminal 50 and the audio terminal 40 of the audio jack 100 form another electrical path allowing the mobile communications device to transmit the audio signals to the headset.
It will be apparent to those skilled in the art that various modifications and variations can be made to the structure of the present invention without departing from the scope or spirit of the invention. In view of the foregoing, it is intended that the present invention cover modifications and variations of this invention provided they fall within the scope of the following claims and their equivalents.
