Abstract
A metal sheathed heater includes a thermostat, a means for mounting the thermostat in a secure location, and a joint interconnecting the thermostat with a source of power and a lead wire of the metal sheathed heater. The joint is a type that is moisture and abrasion resistant, mechanically strong, and electrically insulating.
Claims5
In an heater having a metal sheath encasing a heater cable, a clamp assembly attached to ends of the metal sheath for securing the metal sheath to a component for heating purposes, heater lead wires, and a connection where each end of the heater cable connects to a respective end of each heater lead wire, the improvement comprising a thermostat with a pair of thermostat lead wires forming an assembly with the metal sheathed heater, one thermostat lead wire adapted to connect to one of the heater lead wires with the other thermostat lead wire adapted to connect to a source of power, means for mounting the thermostat to a structure to allow for temperature sensing, and a connection joining the one heater lead wire to the one wire of the pair of lead wires, the connection being a high strength, moisture and abrasion resistant, and electrically insulating type, wherein the connection is one of the following:
- a) a splice connection further comprising a crimpable splice interconnecting the wire portion of each of the one thermostat lead wire and the one heater lead wire, a layer of adhesive covering an end portion of an insulating layer of the one heater wire and the one thermostat lead wire, and a heat shrinkable tube sized to cover the end portions and the crimpable splice;
- b) a splice connection further comprising a crimpable splice interconnecting the wire portion of each of the one thermostat lead wire and the one heater lead wire, a potting material covering the crimpable slice and an end portion of an insulating layer of the one heater lead wire and the one thermostat lead wire, and a heat shrinkable tube sized to cover the potting material;
- or
- c) a splice connection further comprising a crimpable splice interconnecting the wire portion of each of the one thermostat lead wire and the one heater lead wire, and a potting material covering the crimpable splice and an end portion of an insulating layer of each of the one heater lead wire and the one thermostat lead wire.
