Abstract
A thermochromic pellet for a thermochromic indicator of the heating of an electrical connection terminal of an electrical unit, is configured to change colour when its temperature exceeds a predetermined transition temperature. The thermochromic pellet is further configured to be fixed reversibly to a support limb belonging to the thermochromic indicator and fixed to the terminal.
Claims18
An electrical unit comprising:
- one or more electrical connection terminals;
- one or more thermochromic indicators, each of the thermochromic indicators being associated with a respective terminal from the one or more electrical connection terminals, each of the thermochromic indicators respectively comprising:
- a thermochromic pellet configured to change color when a temperature of the thermochromic pellet exceeds a predetermined transition temperature;
- and
- a support limb formed from a thermally conductive material, the support limb including:
- a fixing portion fixed to the respective terminal;
- and
- an indicating portion distinct from the fixing portion, the indicating portion having one or more protrusions;
- and
- wherein the thermochromic pellet includes a cavity configured to engage with the one or more protrusions of the indicating portion, the thermochromic pellet being configured to be reversibly attached to the indicating portion.
