  • Armoured resistor with an end sealing element
    Patent number: 9293283
    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.
    Type: Grant
    Filed: May 31, 2011
    Date of Patent: March 22, 2016
    Assignee: I.R.C.A. S.P.A. INDUSTRIA RESISTENZE CORAZZATE E AFFINI
    Inventors: Roberto Colombo, Gianni Palu′, Maurizio Biasi
  • Electric air heater, in particular for electrical domestic appliances
    Patent number: 8750692
    Abstract: Electric air heater, in particular for electrical domestic appliances, comprising at least one heating element (20) provided with an insulated supporting element (21) on which at least one resistance wire (22) is wound. An electrical connector (17) clamps, with at least one electrical pin (18), said at least one heating element (20), tapping at least one end of said resistance wire (22). The electrical connections of a thermostat (15) and/or a thermistor (14) are made by means of electrical tracks (16) formed directly on a surface (25) of housing (13) to which said thermostat (15) and/or thermistor (14) are attached. Said electrical connector (17) clamps said surface (25) with at least one further electrical pin.
