Claims26
A thermal tool comprising:
- a frame having a pair of oppositely disposed prongs each terminating in a chuck;
- a pair of thermal cartridges each having a thermal distal end assembly with a first portion designed to fit securely within said chucks of said frame, each thermal distal end assembly further including a hollow section projecting at an angel from said first portion and a blade or tip attached to said hollow section;
- and
- a pair of heater assemblies each shaped and sized to fit securely within said hollow section of said thermal cartridges.
A thermal wire stripper comprising:
- a frame having a pair of oppositely disposed prongs each terminating in a pair of chucks, each chuck having a cutout at its distal end;
- and
- a pair of blade cartridges each having stripping blades, the stripping blades having a first portion designed to fit securely within said chucks of said frame, a part cylindrical hollow section extending at an angle from said first portion, said part cylindrical hollow section removably enclosing a heater assembly, and a blade extending from said part cylindrical section, whereby said cutout of said chuck has a shape matching the shape of an exterior surface of said part cylindrical hollow section of said stripping blades to precisely align and position said stripping blades within said chucks preventing rotational misalignment of said stripping blades.
A thermal tool comprising:
- a frame having a pair of oppositely disposed prongs each terminating in a pair of chucks, each chuck having a cutout at its distal end;
- a pair of cartridges each having a distal end, each distal end having a first portion designed to fit securely within said chucks of said frame, a part cylindrical hollow section extending at an angel to said first portion, said part cylindrical hollow section enclosing a heater assembly, and an edge extending from said part cylindrical section, said cartridges further including a sleeve secured at a distal end to said first portion of said blades and at a proximal end to a connector;
- and
- each of said pair of distal ends is securely affixed within said pair of chucks to have distal end faces beveled at an angle whereby when opposing edges of said distal end faces are touched together, said flat distal end faces define an obtuse angle.
A replaceable cartridge for a thermal tool, comprising:
- a blade, a sleeve secured at a distal end to a first portion of said blade and at a proximal end to a connector, and a heater assembly;
- said blade having a first portion designed to fit securely within a chuck of a frame of a thermal tool;
- a part cylindrical section extending generally perpendicular to said first portion, said part cylindrical section having a hollow axial section for receiving said heater assembly;
- and
- a blade extending from said part cylindrical section.
A two piece stripping blade for a thermal wire stripper, comprising:
- a blade body having a first portion designed to fit securely within a chuck of a frame of a thermal wire stripper and a part cylindrical section extending generally perpendicular to said first portion, said part cylindrical section having a hollow axial section for removably receiving a heater assembly;
- and
- a blade removably attached to said part cylindrical section of said blade body whereby said blade may be removed and replaced.
A thermal tool comprising:
- a frame having a pair of oppositely disposed prongs each terminating in a chuck;
- a pair of cartridges each having a thermal distal end assembly having a first thermal tip portion, a central sleeve and a proximal connector, each thermal tip portion designed to fit securely within said chucks of said frame, each thermal tip portion further including a hollow section encasing a heater assembly shaped and sized to fit securely within said hollow section.
A heating tool comprising:
- a frame having a pair of oppositely disposed prongs each terminating in a chuck;
- and
- a pair of blade cartridges each having a stripping blade having a first portion designed to fit securely within said chucks of said frame, and a pair of heater assemblies within said stripping blades.
A method of assembling a replaceable stripping cartridge for a thermal tool having a frame including a pair of oppositely disposed and resiliently biased prongs, each prong terminating in a chuck, the method comprising:
- forming a stripping blade having a first portion designed to fit securely within a chuck of a frame of a thermal tool, a part cylindrical section extending at a generally perpendicular angle of 70 to 120 degrees to said first portion, said part cylindrical section having a hollow axial section for removably receiving a heater assembly, and a blade extending from said part cylindrical section;
- forming a heater coil from a Kanthal wire and a ceramic core and attaching the ends of the Kanthal wire to conductors;
- inserting said heater assembly into said hollow axial section of said part cylindrical section of said stripping blade;
- threading said conductors attached to said Kanthal wire heater coil through said first portion of said stripping blade;
- inserting said conductors and the proximal end of said first portion of said stripping blade into the distal end of a sleeve;
- attaching a connector to the proximal end of said conductors and said sleeve, said stripping blade, said sleeve and said connector forming a stripping cartridge;
- and
- inserting said connector end of said stripping cartridge through said chuck until said part cylindrical section of said stripping blade engages with said chuck and said connector establishes electrical contact with a connector socket mounted in the frame of said thermal tool.
A thermal tool comprising:
- a frame having a pair of oppositely disposed prongs each terminating in a chuck;
- and
- a pair of cartridges each having a thermal distal end assembly having a thermal tip portion, a central sleeve and a proximal connector, each thermal tip portion designed to fit securely within said chucks of said frame, each thermal tip portion further including a heater assembly.
