Abstract
A portable thermal wire stripper has a pair of heatable stripping blades which are electrically attached to an electrical power and control system. The electrical system converts a direct current output from a battery which is housed in the wire stripper into a variable alternating current power which is used for controlling the surface temperature of the heated blades.
Claims26
A portable device for stripping insulation from a wire for use with a source of direct current which comprises:
- a heating element;
- means to chop direct current from said source into pulses of direct current;
- means to vary the duration of said pulses;
- and
- switching means for inductively coupling said direct current power to said heating element to heat said heating element in proportion to the duration of said pulses.
A wire insulation stripping device for use with a direct current power source which comprises:
- an electrical heating element;
- means for adjustably converting said direct current from said power source to pulses of direct current, said pulses having an adjustable duration;
- and
- coupling means between said converting means and said heating element to establish an element temperature proportional to said duration of said pulses.
A method for stripping insulation from wires, comprising the steps of:
- selectively chopping direct current power to pulses of direct current;
- exciting an oscillator in response to the duration of said pulses to generate a flip-flop switching signal;
- coupling said direct current power to an electrical heating element to heat said heating element in response to said flip-flop switching signal;
- and
- positioning said heating element adjacent said insulation to heat said insulation for stripping said insulation from said wires.
A wire insulation stripping device for use with a direct current power source which comprises:
- heating means;
- means to convert said direct current power to an adjustable direct current pulses;
- and
- means to couple said direct current power to said insulation heating means to establish a temperature on said wire heating means in proportion to said direct current pulses.
A method for stripping insulation from a wire core, comprising the steps of:
- chopping direct current power to direct current pulses;
- varying the duration of said pulses;
- generating a flip-flop switching signal in response to said pulses;
- coupling said direct current power to a stripping blade to heat said blade in response to said switching signal;
- positioning said stripping blade adjacent said insulation to partially melt said insulation;
- and
- stripping said partially melted insulation from said wire.
