Title:
TERMINAL BLOCK
Document Type and Number:
WIPO Patent Application WO/2019/205115
Kind Code:
A1
Abstract:
It provides a terminal block including: an insulating body, having a duct and at least one hole formed through a wall of the insulating body, a conductive linking bar in the insulating body for connecting at least one wire respectively passing through the at least one hole, a temperature detector partially received by the duct and made of thermal conductive material exhibiting thermal resistivity lower than the insulating body having at least one first end, a second end, and a connecting portion mechanically linking the first end and the second end, and a discoloration layer in contact with the second end of the temperature detector having at least a thermochromic layer. The first end and at least a part of the connecting portion of the temperature detector is arranged to pass through the duct towards the conductive linking bar so that the discoloration layer on the second end of the temperature detector is farther to the conductive linking bar than the first end of the temperature detector. By having such arrangement, it is helpful to allow the discoloration layer to be viewed by an external observer indicating overheating in the terminal block, thus make it more sensitive to the internal temperature of the terminal block.
