Abstract

A multi-directional hand-free kit. The kit has a main body receiving a printed circuit board therein for controlling audio signal sending and receiving incorporated with a mobile communication device and formed with a first oblique portion, a connector member connected to an external power source and formed at a portion thereof facing the first oblique portion with a second oblique portion which frictionally makes contact with the first oblique portion, and a shaft member for connecting the main body and the connector member in such a manner that the main body and the connector member are obliquely rotatable to each other.

Claims

1. A hand-free kit for a wireless communication device, comprising:

a main body including a printed circuit board for controlling audio signal sending and receiving with respect to a communication device, and formed at one side thereof with a first oblique portion;

a connector member for connection with an external power source so as to electrically communicate with the printed circuit board, the connector member being formed at a portion of said main body thereof facing the first oblique portion with a second oblique portion inclined by a substantially identical angle to an inclined angle of the first oblique portion, the second oblique portion frictionally making contact with the first oblique portion; and

a shaft member for connecting the main body and the connector member in such a manner that the main body and the connector member are obliquely rotatable to each other.

2. The kit as recited in claim 1, wherein the main body includes first and second housings which are detachable from each other and a speaker portion for forwardly propagating a sound wave, the speaker portion being electrically connected to the printed circuit board.

3. The kit as recited in claim 2, wherein the main body includes at outer sides thereof a microphone socket, an earphone socket, a light emitting diode for indicating operational modes of the printed circuit board and a volume knob for controlling a volume of an audio signal propagating outwardly from the speaker portion, each of which being electrically connected to the printed circuit board.

4. The kit as recited in claim 3, wherein the speaker portion, the microphone socket, the earphone socket and the light emitting diode turn with respect to the shaft member when the,,main body rotates.

5. The kit as recited in claim 1, wherein the connector member includes third and fourth housings extending in one direction and detachable from each other, and includes at a first portion thereof a pin which is made of a conductive that extends outwardly toward external power source, the connector member further receiving a fuse therein for preventing an over-current condition.

6. The kit as recited in claim 5, wherein a compression spring is disposed between the pin and the fuse so as to urge the pin toward an external power source.

7. The kit as recited in claim 5, wherein the first portion of the connector member is inserted into a holder having a ring shape, and a cap is engaged with the first portion for assembling the third and fourth housing together with the holder.

8. The kit as recited in claim 5, wherein the connector member is provided at both sides with plate springs bent outwardly by a predetermined thickness so as to be stably inserted into the external power source.

9. The kit as recited in claim 5, wherein the shaft member has a substantially cylindrical shape, is formed at a first end portion thereof with first and second flanges, and is formed at a second end portion thereof with an annular groove, the first and second flanges being slidably engaged with the second oblique portion of the connector member, the annular groove being inserted through the first oblique portion of the main body by a predetermined depth.

10. The kit as recited in claim 9, wherein an axial direction of the shaft member is orthogonal to the first and second oblique portions.

11. The kit as recited in claim 9, wherein the first and second flanges are spaced apart from each other by a predetermined interval substantially identical to a thickness of the second oblique portion so as to be inserted into an opening formed at the second oblique portion, thereby rotatably supporting the main body.

12. The kit as recited in claim 9, wherein an E-ring is disposed around the annular groove of the shaft member and makes contact with an inner wall around an opening formed at the first oblique portion so as to prevent the main body from being separated therefrom.

13. The kit as recited in claim 1, wherein the printed circuit board in the main body is electrically connected to the first portion of the connector member by electric lines extending through a core of the shaft member.

14. The kit as recited in claim 1, wherein an O-ring is disposed around the shaft member between the main body and the connector member for allowing the main body to smoothly slide with respect to the connector body.
