Abstract

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.
