ABSTRACT:

BACKGROUND OF THE INVENTION
The present invention relates to a charging paddle of an inductive charger coupling, more particularly, to a noise reduction structure of a charging paddle. An inductive charger coupling typically includes a receptacle and a charging paddle, which supplies electricity to the receptacle from a power source.
FIG. 8
illustrates an inductive charger coupling, which includes a charging paddle
1
and a receptacle
6
. The paddle
1
is attached to the distal end of a cable
3
, which is connected to an electricity supplying apparatus
2
. The receptacle
6
is located in an electric vehicle
5
, which has a battery
4
. As shown by dotted line in
FIG. 8
, the paddle
1
is plugged into the receptacle
6
. The battery
4
is charged by electromagnetic induction between a coil in the paddle
1
and a coil in the receptacle
6
.
When electricity is supplied from the electricity supplying apparatus
2
to the battery
4
through the paddle
1
and the receptacle
6
, radiation noise is produced by the coils of the paddle
1
and the receptacle
6
. The radiation noise adversely affects communication devices and other devices. To prevent radiation noise from escaping from the receptacle
6
, the receptacle
6
is made of aluminum. Also, the paddle
1
has shielding member made of conductive resin. When the paddle
1
is plugged into the receptacle
6
, the shielding member closes the opening of the receptacle
6
. A plurality of conductive terminals are arranged at the opening of the receptacle
6
. When the paddle
1
is in the receptacle
6
, the terminals contact the shielding member. Radiation noise is absorbed by the shielding member, which is made of conductive resin, and is converted into a noise current. The noise current flows from the shielding member to a vehicle grounding terminal through the conductive terminals.
However, the shielding member has a relatively high resistance. Thus, the noise current flowing through the shielding member is limited, which hinders noise prevention.
SUMMARY OF THE INVENTION
Accordingly, it is an objective of the present invention to provide a charging paddle that effectively prevents radiation noise from escaping.
To achieve the foregoing and other objective and in accordance with the purpose of the present invention, a paddle of an inductive charger coupling is provided. The paddle is connected to a power source through a power line. Part of the power line is located in the paddle. The paddle is inserted into an opening of a receptacle for supplying electricity to a receptacle. The paddle includes a case, a conductive metal member and a conductor. The conductive metal member is located in the case. The conductive metal member absorbs noise radiated from the power line in the paddle and converts the absorbed noise into a noise current. The conductor conducts the noise current to the outside of the paddle. The conductor is electrically connected to the conductive metal member in the paddle.
Other aspects and advantages of the invention will become apparent from the following description, taken in conjunction with the accompanying drawings, illustrating by way of example the principles of the invention.
