Embodiment Construction

[0053] The following description is merely exemplary in nature and is not intended to limit the disclosure, application or uses. It should be understood that throughout the drawings, corresponding reference numerals indicate like or corresponding parts and features.

[0054] refer to Figure 1 to Figure 4 , shows an electric heater 10 . In the example provided, electric heater 10 may be used to heat a paving medium (eg, asphalt) in a mortar paving machine that may be used to pave roads and other surfaces on which vehicles operate. As such, electric heater 10 is configured to reach operating temperatures up to about 500°C while being exposed to various oils, fuels, corrosive chemicals, dirt, water, ice, and ambient temperatures below 0°C. It should be understood that the teachings of the present disclosure may be applied to other heater applications as well.

[0055] The electric heater 10 includes a heating member 14 , a power cable 18 and a connector assembly 22 . The hea...

Abstract

An electrical heater (10) and method includes heating member (14), a cable (18), and a connector (22). A resistance heating element (30) is within a sheath (26) of the heating member. A proximal end of the sheath is inserted into a slot of a first fitting (110) and welded to the first fitting with first and second leads extending into the first fitting. The second fitting (114) is threadably engaged with the first fitting. The second fitting defines a central bore disposed about the axis. An end of a power cable extends into the second central bore. A first wire is coupled to the first lead. Asecond wire is coupled to the second lead.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to provisional application 62 / 632,273, filed February 19, 2018. The disclosures of the aforementioned applications are incorporated herein by reference. technical field [0003] The present disclosure relates to connector assemblies for high voltage electric heaters. Background technique [0004] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0005] High voltage electric heaters typically include a power cable coupled to a resistive heating element configured to generate heat. The heating element is usually enclosed in a thermally conductive dielectric material surrounded by a metal sheath. The sheath protects the heating element, and in some applications, the sheath is configured to be submerged in a fluid. In other applications, the jacket may be attached to a radiator or heat exchanger to ...
