Armoured resistor with an end sealing element

摘要

Armored resistor with an end sealing element in which the electric pin (2) partially projecting from an end (1′) of the armor (1) and connected to said end by said sealing element (5) is provided with a part (22) with high roughness, i.e. knurling and/or toothing (22′, 22″, 22′″) and/or a circular groove (23, 23′), moreover said end (1′) of the armor is crimped in order to compress said sealing element (5) against said zone with high roughness.

1. An armoured resistor with two caps, of domestic appliances, comprising
an armour having two opposite ends, one first end of said opposite ends defining an axis of longitudinal extension (X), an electric pin partially projecting from said first end and connected to said first end by an annular element with axial symmetry comprising a through-cavity engaged by said electric pin so that the electric pin is coaxial with said axis of longitudinal extension (X), a thermal fuse arranged internally in said armour and electrically connected to said electric pin, the electric pin having a portion of peripheral surface in contact with the through-cavity of said annular element, characterized in that said portion of peripheral surface comprises knurling or toothing defining at least one component of extension parallel to said axis of longitudinal extension (X).
