Title:
TERMINAL OVERHEAT DETECTOR
Document Type and Number:
Japanese Patent JP2017183244
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a terminal overheat detector capable of detecting abnormal overheat of terminal by simple configuration, without modifying a circuit breaker, and capable of confirming whether or not a normal output can be obtained by test operation.MEANS FOR SOLVING THE PROBLEM: A terminal overheat detector attached to the terminal of an electrical apparatus and displaying the temperature of the terminal includes a connection connected with the terminal and to which the heat thereof is conducted, a thermal element having one end fixed to the connection and the other end disposed to displace freely in response to change of heat, a displacement transmission part to which displacement of the thermal element is transmitted and which reciprocates corresponding to response, a display mechanism which is driven by displacement transmitted from the displacement transmission part, and a signal output part which is driven when the displacement transmitted from the displacement transmission part exceeds a predetermined threshold.SELECTED DRAWING: Figure 1
