Abstract:
A method for insulating leads of a thermal fuse with insulating tubes (4), said thermal fuse comprising a fusible alloy (6) accommodated in an insulating case (1), and leads (3) that are connected to both ends of said fusible alloy (6) and that protrude externally from seals (2) provided on openings of the both ends of said insulating case (1), wherein an inner diameter of the insulating tubes (4) and an outer diameter of the leads (3) is chosen so that there exists a hollow space for an adhesive (5) between an outer circumference of the leads (3) and an inner circumference of the insulating tubes (4) put on the leads (3), in which method, the adhesive (5) is applied to the circumferences of said leads (3), and the insulating tubes (4) are put on surfaces of the leads (3) while rotating the insulating tubes (4), so that the adhesive (5) is present inside the insulating tubes (4) in said hollow space.
