Title:
ELECTRICAL CONNECTION USING WORM GEAR
Document Type and Number:
Japanese Patent JP2003231072
Kind Code:
A
Abstract:

To prevent a power feed cord from twisting even if electric equipment is rotated in an electrically connected state by transmitting a rotation in the direction of twisting the power feed cord to a worm gear when using the electric equipment such as an electric drill and a hair dryer handled with its cord connected to a power supply.

A conductive material is used for worms and worm wheels constituting the worm gear and the plurality of worms are disposed on a same rotary shaft. A power feed terminal electrically connected to the respective worms is provided along the same rotary shaft as the worms and power incoming terminals electrically connected to the worm wheels assembled with the respective worms are provided. The worms and the worm wheels are so geared as to constantly contact to each other and retain the electrical connection. The electrical connection using the worm gear of the aforementioned constitution is disposed between the power feed cord and the electric equipment receiving the power. The power feed terminal/the worms and the worm wheels/the power receiving terminals are mutually rotated around the rotary shaft of the worms and the energization is retained by the contact between the worms and the worm wheels.
