ABSTRACT:

BACKGROUND OF THE INVENTION
The present invention relates to electric connectors and, more particularly, to a vibrator connector adapted to connect a vibrator to a circuit board.
Following fast development of telecommunication technology, a variety of mobile telephones have been disclosed, and are intensively used for communication for the advantage of high mobility. Modern mobile telephones are commonly equipped with a vibrator to provide a silent mode. When receiving a message under the silent mode, the vibrator is triggered to vibrate, informing the user of the incoming of the message. The vibrator is connected to a circuit board through a vibrator connector.
FIGS. 8 and 9
show a vibrator connector according to the prior art. This structure of vibrator connector comprises an electrically insulative shell B, and two terminals A respectively mounted in the shell B. The shell B comprises two terminal slots B
1
, and two stop edges B
11
respective disposed in the terminal slots B
1
. The terminals A are respectively mounted in the terminal slots B
1
, each comprising a contact arm A
3
, a stop face A
31
stopped against one stop edge B
11
of the shell B, a receptacle portion A
4
, a connecting portion A
1
connected to the circuit board, and a retaining strip A
2
secured to the peripheral wall of the respective terminal slot B
1
. The vibrator C has lead wires connected to a matching connector comprised of an electrically insulative shell D, which is coupled to the shell B, and two terminals D
1
, which are respectively fastened to the receptacle portion A
4
of each of the terminals A. This structure of vibrator connector has drawbacks. Because a matching connector D;D
1
must be used with the vibrator connector to connect the vibrator C to the circuit board, the installation cost of the vibrator C is high. Further after insertion of the terminals A in the terminal slots B
1
of the shell B, a special tool must be used to bent the retaining strip A
2
, enabling the retaining strip A
2
to be secured to the respective terminal slot B
1
.
SUMMARY OF THE INVENTION
The present invention has been accomplished to provide a vibrator connector, which eliminates the aforesaid drawbacks. According to one aspect of the present invention, the vibrator connector comprises an electrically insulative shell mounted on the circuit board, the shell having two parallel terminal slots extended in reversed directions and a top stop wall spaced above the terminal slots, and two terminals mounted in the terminal slots inside the shell, the terminals each having a connecting plate soldered to the circuit board, a curved springy extension arm stopped below the top stop wall of the shell and terminating in a contact portion suspending above the top stop wall of the shell and disposed in contact with a respective contact of the vibrator. According to another aspect of the present invention, the electrically insulative shell comprises two retaining notches respectively disposed in the terminal slots at one side, and the terminals each comprise a stop tooth obliquely backwardly extended from the respective mounting base and respectively engaged into the retaining notch in each of the terminal slots of the electrically insulative shell.
