ABSTRACT:
An improved thermal barrier for rigidly connecting the heater assembly to a handle assembly in a desoldering device. In a preferred embodiment, the thermal barrier includes a slotted spacer portion which is connected to the heater assembly and serves to reduce heat transferred into the thermal barrier by means of radiation, convection and reduced conductivity. The thermal barrier also includes a portion connecting the slotted spacer portions to mounting sections which are connected to the handle assembly such that an indirect path for heat conduction is established between the heater assembly and the handle assembly. In some preferred embodiments, a fin is included to increase the surface area of the thermal barrier and further transfer heat from the thermal barrier to the atmosphere. A further embodiment includes a slotted fin which not only increases the surface area of the thermal barrier but also increases the resistance to heat conductivity further improving the thermal characteristics of the heat barrier.
