Abstract

A cable cutter for cutting a cable by using an explosive event is provided. The cable cutter includes a main body and an initiator assembly connected to the main body. The main cutter includes a cutterjaw and a receptacle having an opening accommodating a cable, a longitudinal bore formed in the housing and connected to the receptacle and having an inner opening and an outer opening, a cutter blade having a cutting edge facing the inner opening and a base facing the outer opening, being inserted into the bore of the receptacle, and slidably moving toward the cutter jaw within the bore of the receptacle to cut a cable disposed within the receptacle and between the cutter jaw and the cutting edge of the cutter blade. The initiator assembly includes a coupler, a passageway formed within the coupler, a cap covering having a hole connected to the coupler, and an explosive material and detonator are inserted through the hole in the cap into the passageway. A cone shaped surface is extended from a circumferential inner surface of one end of the passageway to an opening of the coupler connected to the main body.

Dependent claims

A cutting device, comprising:

a main body, with first and second ends, having a workpiece holder formed on said first end of said main body;
a bore having enter and exit ends formed inside of said main body wherein said first end faces said workpiece holder;
a cutter having a blade and a base disposed within said bore, said blade proximate to said exit end and said base proximate to said enter end;
a coupler having a passageway formed inside of said coupler and having front and back ends, said front end of said coupler connected to said second end of said main body wherein said bore and said passageway align;
forward and rear portions of said passageway, said forward portion proximate to said front end of said coupler having a diameter wherein said diameter enlarges in approximately a conical shape;
a cap coupled to said back end of said coupler, having a hole formed on said cap;
an explosive material within said passageway;
and,
means to detonate said explosive material inserted through said hole of said cap wherein detonation creates a shock wave directed by said conical shape to push said base of said cutter so that said blade of said cutter passes through said workpiece holder.
