SPARK-RESISTANT PLUG STRUCTURE AND POWER SUPPLY ADAPTOR

Title:

SPARK-RESISTANT PLUG STRUCTURE AND POWER SUPPLY ADAPTOR

Document Type and Number:

WIPO Patent Application WO/2009/152660

Kind Code:

A1

Abstract:

A spark-resistant plug includes a first terminal set (11) comprising a first anode terminal (12), a second anode terminal (13) and a first cathode terminal (14); and a second terminal set (21) comprising a third anode terminal (22), a fourth anode terminal (23) and a second cathode terminal (24), which are adapted to connect with the first anode terminal, the second anode terminal and the first cathode terminal correspondingly. Firstly, the fourth anode terminal is contacted with the second anode terminal, and the second cathode terminal is contacted with the first cathode terminal when they are connected with each other. Then the third anode terminal is contacted with the first anode terminal. A resistor (25) is in series with the fourth anode terminal. The plug can be used to prevent an electrical appliance with a capacitor from being broken because of an arc spark generated instantaneously when the electrical appliance is electrified.
