A heater assembly includes a pair of heating sections and a coupling assembly. The heating sections each include a conductive portion. The coupling assembly includes a coupling enclosure and a coupling member disposed inside the coupling enclosure. The conductive portions of the pair of heating sections are connected by the coupling member inside the coupling enclosure.

The present invention provides a device that reduces thermal influence from heated elements of equipment on the findings of the tubular electric heater and lowers the temperature of the host electrical connection. Tubular unit heaters include flange (cover) with threaded holes and bushings, which are rigidly sealed tubular heaters with the conclusions and findings of the tubular electric heater made of electric portable node connections, and protective jacket, which is mounted on the flange from the insights of the tubular heater, offered on the module flange tubular electric heaters, from the insights of tubular electric heaters, set the cylindrical shell, on the upper half of which to perform a through perforation, on the inner surface of the cylindrical shell rigidly fix at least two heat shields with holes for tubular electric heaters, and the diameter of the holes in the heat shields should exceed the outer diameter of the sleeve.

A connection unit for an exhaust gas heater in an exhaust gas system of a combustion engine includes an electrically conducting connection element, elongated in the direction of a connection element longitudinal axis (L). The connection element has an inner connection region for connection to a heating conductor and an outer connection region for connection to an electrical supply. A carrier arrangement surrounds the connection element and an insulating arrangement insulates the connection element with respect to the carrier arrangement.

A heater includes a first conducting pin, a second conducting pin, and a plurality of resistance coils. Each resistance coil includes a first end connected to the first conducting pin and a second end connected to the second conducting pin. At least one resistance coil among the plurality of resistance coils has a continuously variable pitch. In one form, the plurality of resistance coils are connected in a parallel circuit with the first and second conducting pin. A first resistance coil among the plurality of resistance coils may have a diameter that is different than a second resistance coil among the plurality of resistance coils.

A resistance element includes a resistance coil having a first end and a second end opposite the first end. The resistance coil defines a plurality of first portions defining a first constant diameter and a plurality of second portions defining a second constant diameter smaller than the first diameter. At least one of the first portions and the second portions has a continuously variable pitch. The resistance coil may also further define two third portions, each third portion being disposed adjacent to a corresponding first or second end. The resistance element may be disposed between first and second conducting pins in a heater.

A splice for a skin-effect effect heating cable is provided. The splice includes a primary shim configured to be shrunk over part of an insulation layer of a first portion of the heating cable, a secondary shim configured to be shrunk part of the insulation layer of a second portion of the heating cable, a connector configured to electrically couple the first portion of the heating cable and the second portion of the heating cable, and an outer cold shrink tube configured to be shrunk over the primary shim, the secondary shim, and the connector.
