Title: Terminal box for detection switch with connector
Inventor: TANAKA KUNIAKI
IPC: H01H36/00
Filed: 1999-02-12
Abstract: PROBLEM TO BE SOLVED: To easily enable the inspection of a detection switch by providing a lamp circuit capable of lighting a lamp in a terminal box main body and by connecting the terminal of the lamp circuit to the terminal of the detection switch. SOLUTION: This detection switch (proximity switch) 30 opens terminals 30a and 30b when a metal is not close to it. A power source 15 carries current through a rectifier S of a lamp circuit so that a lamp (LED) L is lit by a rectified direct-current power supply. The lamp circuit is so designed that a current i consumed by the lamp circuit flows through an output detector 20 at this time but the current i is set so as not to activate the output detector 20. When the detection switch 30 detects a metal, the terminals 30a and 30b carry current and junction terminals 2A and 2B also carry current. Thereby, the output detector 20 carries current more than the current i and is activated through a relay. Potential differences are not generated in the rectifier S so that the lamp L is extinguished and the normal conditions can be confirmed.
