Wire splicer

Abstract

A wire splicer has a disk with opposite first and second faces and a plurality of holes extending through said disk between said first and second faces. A nose protrudes convergently from a central portion of the said first face, and the holes are distributed in an annular array extending around and adjacent said nose. A shank extending from said second face in alignment with said nose can be inserted into the chuck of an electric drill for rotating the wire splicer with the ends of wires inserted through the holes to splice the wire ends together. A method of splicing wires employs such a wire splicer.

1 . A splicer, comprising;
 a splicer head;   said splicer head having opposite first and second sides, a central portion and a plurality of wire reception holes open at said first side of said splicer head;   a wire guide and spreader boss protruding from said central portion at said first side of said splicer head;   said wire reception holes being distributed around said wire guide and spreader boss;   said wire guide and spreader boss having a surface which converges outwardly from said first side of said splicer head; and   a shank projecting from said central portion of said splicer head at said second side of said splicer head.   
   
   
       2 . A wire splicer as claimed in  claim 1 , wherein said wire reception holes each taper convergently from said first side of said splicer head. 
   
   
       3 . A wire and splicer as claimed in  claim 2 , wherein said wire reception holes have frusto-conical surfaces. 
   
   
       4 . A wire splicer as claimed in  claim 3 , wherein said wire reception holes are counterbored holes. 
   
   
       5 . A wire splicer as claimed in  claim 2 , wherein said holes extend through said splicer head from said first side to said second side of said splicer head. 
   
   
       6 . A wire splicer as claimed in  claim 1 , wherein an opening extends through said splicer head at said central portion, said shank has an end portion extending through said opening and said boss is formed on said end portion of said shank. 
   
   
       7 . A wire splicer, comprising:
 a disk;   said disk having opposite first and second faces and a plurality of holes extending through said disk between said first and second faces;   a nose protruding convergently from said first face;   said holes being distributed in an annular array extending around and adjacent said nose; and   a shank extending from said second face in alignment with said nose.   
   
   
       8 . A wire splicer as claimed in  claim 7 , wherein said holes teach taper convergently from said first face. 
   
   
       9 . A wire splicer as claimed in  claim 7 , wherein said holes are counter-bored. 
   
   
       10 . A wire splicer as claimed in  claim 7 , wherein said nose is frusto-conical, with a rounded tip. 
   
   
       11 . A wire splicer as claimed in  claim 7 , wherein said disk has a smooth annular periphery. 
   
   
       12 . In combination, a pair of wires and a wire splicer,
 the wires each comprising wire wires and an insulation sheathing extending around said wire wires;   the wire splicer comprising;   a splicer head;   said splicer head having opposite first and second sides, a central portion and a plurality of wire reception holes open at said first side of said splicer head;   a wire guide and spreader boss protruding from said central portion at said first side of said splicer head;   said wire reception holes being distributed around said wire guide and spreader boss;   said wire guide and spreader boss having a surface which converges outwardly from said first side of said splicer head; and   a shank projecting from said central portion of said splicer head at said second side of said splicer head,   said wire reception holes each having a shape which tapers towards said second side of said splicer head to a cross-sectional area which is sufficient to receive therethrough one of said wires but which is less than the cross-sectional area of said insolation on said wire.   
   
   
       13 . A wire splicer as claimed in  claim 12 , wherein said wire reception holes are counterbored holes. 
   
   
       14 . A wire splicer, comprising;
 a splicer head;   said splicer head having opposite first and second sides, a central portion and a plurality of wire reception holes open at said first side of said splicer head; and   a wire guide and spreader boss protruding from said central portion at said first side of said splicer head;   said wire reception holes being distributed around said wire guide and spreader boss; and   said wire guide and spreader boss having a wire guide surface which converges outwardly from said first side of said splicer head.   
   
   
       15 . A wire splicer as claimed in  claim 14 , wherein said wire reception holes each taper convergently from said first side of said splicer head. 
   
   
       16 . A method of splicing wires, comprising the steps of:
 displacing the wires towards a wire splicer;   deflecting the wires on a nose on said wire splicer towards respective holes in said splicer so as to guide end portions of said wires into said holes; and   rotating said wire splicer to splice said end portions of said wires together.   
   
   
       17 . A method as claimed in  claim 16 , which includes providing the holes with minimum cross-sectional areas less than the cross-sectional area of insulation sheathing on the end portions of the wires and restricting the passage of the insulation sheathing into the holes by abutment of the insulation sheathing against sides of said holes at the cross-sectional areas of the holes.
