## Abstract

A connecting device includes an input portion, a first connecting member, a second connecting member, a wire and an output portion. The input portion is configured for electrically connecting to one of the two electronic devices. The first connecting member includes a first surface. The first surface forms a number of first electrical contacts electrically connected to the input portion. The output portion is configured for electrically connecting to the other electronic devices. The second connecting member includes a second surface, the second surface forms a number of second electrical contacts electrically connected to the output portion via the wire. The first and second connecting members magnetically attract each other so that the first and the second surface contact each other, and as a result, the first and second electrical contacts communicate with each other.

## Claims

### Claim 1

A connecting device for interconnecting two electronic devices, the connecting device comprising:
an input portion configured for electrically connecting to one of the electronic devices;
a first connecting member comprising a first surface, the first surface being flat and forming a plurality of first electrical contacts electrically connected to the input portion;
an output portion configured for electrically connecting to the other electronic device;
a second connecting member comprising a second surface, the second surface being flat and forming a second electrical contact electrically connected to the output portion; and
a projection protruded upward from the center of the first surface the projection having a plurality of first electrical contacts formed thereon an opening being defined in the center of the second surface corresponding to the location of the projection, the opening having a bottom surface having a plurality of second electrical contacts defined thereon, the first and second connecting members being capable of magnetically attracting each other so that the first and the second surfaces contact and the first and second electrical contacts electrically communicate.

### Claim 2 (depends on 1)

The connecting device as claimed in claim 1, wherein the input portion comprises a plug compliant with universal serial bus standard.

### Claim 3 (depends on 1)

The connecting device as claimed in claim 1, wherein the input portion and the first connecting member are integrally formed.

### Claim 4 (depends on 1)

The connecting device as claimed in claim 1, wherein the first electrical contacts are male pins, the second connecting contacts are female pins for receiving the first electrical contacts.

### Claim 5 (depends on 1)

The connecting device as claimed in claim 1, wherein the output portion comprises a universal serial bus plug.

### Claim 6 (depends on 1)

The connecting device as claimed in claim 1, wherein the connecting device further includes a first attracting member and the second attracting member, the first attracting member surrounds the projection, the second attracting member surrounds the opening.

### Claim 7 (depends on 1)

The connecting device as claimed in claim 1, wherein the second connecting member is electrically wired to the output portion.

### Claim 8 (depends on 1)

The connecting device as claimed in claim 1, wherein the first and the second connecting members are made of permanent magnetic material, the first and the second surfaces being magnetized with opposite polarities respectively.

### Claim 9 (depends on 1)

The connecting device as claimed in claim 1, wherein the first and second surface mates with each other so as to be capable of engaging with each other to prevent the first and second connecting member from sliding against each other, thereby, the stability of communication between the first and second electrical contact is ensured.

### Claim 10 (depends on 6)

The connecting device as claimed in claim 6, wherein the first and second attracting member are made of permanent magnetic material and magnetized with opposite polarities respectively.

### Claim 11 (depends on 1)

The connecting device as claimed in claim 1, wherein the first connecting member and the second connecting member are made of plastic cement, except the first and the second surface which are made of permanent magnetic material, and the first and second surfaces are magnetized with opposite polarities.
