Patent ID: 8063732

Claim:
Electrical resistor structure comprising: an electrical resistor ( 3 ) which forms a band which is folded in a serpentine manner so that the band comprises rectilinear portions ( 18 ) which extend in a longitudinal direction of the electrical resistor ( 3 ), and portions ( 19 ) which are curved in a U-shaped manner and which comprise two branches ( 20 , 21 ), the two branches ( 20 , 21 ) being spaced-apart from each other by a distance (D 1 ), a frame ( 2 ) comprising cross-members, and means ( 8 , 9 ) for fixing the electrical resistor ( 3 ), the fixing means ( 8 , 9 , 12 , 14 , 24 ) being fixed to two opposing cross-members ( 5 , 6 ), the fixing means ( 8 , 9 , 12 , 14 , 24 ) comprising spacing members ( 12 ) which are provided with projections ( 14 ) which are spaced-apart from each other and which together define zones ( 24 ) for receiving at least a part of the curved portions ( 19 ), by means of clamping and with a clearance in the longitudinal direction, characterised in that each branch ( 20 , 21 ) of each curved portion ( 19 ) comprises a zone ( 15 ) which is shaped so that the spacing (D 2 ) between the shaped zones ( 15 ) of two branches ( 20 , 21 ) of the same curved portion ( 19 ) is reduced relative to the spacing (D 1 ) between the main faces of the two branches ( 20 , 21 ), the shaped zone ( 15 ) being produced without any cuts or weld seams, the shaped zones ( 15 ) being capable of engaging between the projections ( 14 ) of the spacing members.
