Title:
DISCONNECTION SPARK TESTING MACHINE
Document Type and Number:
Japanese Patent JP3675308
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To surely generate sparks in a disconnected cord for an electric power source.
SOLUTION: This testing machine is provided with a ring-like rotary body 1 rotatedly driven around a shaft, an arm 2 attached to the rotating body 1 to be projected toward an inner circumference side of the rotating body 1, and a holding ring 3 held to the arm 2 and rotatable freely around the shaft. In the ring 3, held insertedly with the disconnected electrical cord 5 of which the core is disconnected, a gyration radius r in rotation of the rotating body 1 is variable by changing a fixing position of the arm 2 on the rotating body 1. Since the rotating track of the cord 5 is fixed, the probability of spark generation is enhanced, and the radius of the rotating track is allowed to be set freely, in response to the kind of the cord 5.
