Abstract

The invention relates to a thermal link (1) for electrical appliances, comprising an insulating part (10) with electrical terminals (11) and contact springs (12) for providing electrical contact between said terminals (11), a fusible material insert (15) that acts as the thermal trip element and a transmission pin (13), which is displaceably mounted in the insulting part (10), one end of which engaging with the fusible material insert (15) and the other end with the contact springs (12). Said link is characterised in that the fusible material insert (15) is situated in a casing (141) that is configured as one piece with the heat transfer plate (14). The invention also relates to a method for producing a thermal link (1) comprising the following steps: the casing (141) for housing the fusible material insert (15) and the casings (144) that connect the heat transfer plate (14) to the insulating part (10) are drawn from the heat transfer plate (14); the fusible material insert (15) is inserted into the casing (141) and formed; the insulating part (10) is placed on the heat transfer plate (14) and connected in a positive fit to the graduated inner sections (107) of the inner cavities (…
