Definitions

  • the present invention relates to metallic sheathed electric resistance heaters, more particularly to such heaters which are hermetically sealed against entrance of moisture or other deleterious substances, and the principal object of the invention is to provide new and improved heaters of the character described, and new and improved methods of making the same.
  • Such a heater assembly is shown and described in Letters Patent No. 2,659,795, assigned to the same assignee as is the instant case.
  • FIGURE 1 is a fragmentary elevational view of a completed heater assembly constructed in accordance with the present invention
  • FIGURE 2 is a view in longitudinal section of the as- 'y sembly seen in FIGURE l, and
  • FIGURES 3, 4 and 5 are views similar to FIGURE 2 but showing successive stages of manufacture.
  • FIGURES l and 2 there is illustrated a conventional electric resistance heating element of the type having a coiled resistor conductor 11 disposed -within a tubular metallic sheath 12 which is filled with electric-insulating, heat-conductive material 13 preferably compacted to a rock-like hardness.
  • Resistor conductor 11 preferably terminates short of the sheath end and a terminal conductor pin 14 is welded or otherwise electrically secured to the conductor 11 within the sheath and projects beyond the sheath end to provide for making an electrical lpower connection to the heating element.
  • a flexible, insulated lead Wire 15 is electrically connected to the protruding portion of the terminal pin 14 in any suitable manner and as herein disclosed, a connector 16 is crimped about their juncture for such purpose.
  • Embedding the juncture aforesaid of the wire and the terminal pin is a mass of cured, rubber-like material 17 3,387,364 Patented June 11, 1968 ICC which extends over both the adjoining end of the shea-th 12 and the insulating covering of the wire 15 and is bonded thereto.
  • Enclosing the mass of material 17 is a rubber-like sleeve 18 bonded to the material mass, the sheath and the wire covering.
  • the bared end of the lead wire 15 will be secured to the terminal pin 14 as by means of a suitable connector 16.
  • the adjoining ends of the sheath 12 and the insulation of the lead wire will be suitably treated to ensure a good bond with the mass of material 17.
  • Such treatment may, if desired, take place before the wire is secured to the terminal pin and may include sand blasting or pickling of the sheath end and the coating of the sheath end and the wire insulation with a suitable adhesive.
  • Ty-Ply-Up supplied by the Marbon Corporation of Gary, Ind.
  • an uncured body of rubber 17 y will be deposited over the juncture of the wire and the pin and preferably spanning the element sheath and the wire covering as shown in FIG- URE 4.
  • a sleeve of dielectric, iiexible, heat-shrinkable material 18 will be slid over the material mass 17, such sleeve preferably being somewhat greater in length than the material mass as illustrated in FIGURE 5.
  • Sleeve 18 is a product of Rayclad Tubes, Incorporated, and is known as Thermofit NT.
  • Such sleeve is formed of a flexible, dielectric, neoprene material which has been so modified in chemical structure that it will shrink in diameter as much as upon subjection to a temperature in excess of 175 C.
