Wire crimping tool

Abstract

A wire crimping tool has two arms and an adjustable wire crimping device. The arms are pivotally connected to each other and each arm has a handle and a jaw. The adjustable wire crimping device is mounted on the jaws of the arms and has a duel crimping cavity and a threaded extension member. The duel crimping cavity is defined in a first one of the jaws and aligns with a second one of the jaws. The duel crimping cavity has an upper segment with a bottom and a lower segment. The lower segment is defined in the bottom of the upper segment and has a diameter smaller than that of the upper segment. The threaded extension member is adjustably mounted in the second jaw and has a crimping tip extending out of the second jaw and aligning with and extending into the duel crimping cavity.

1 . A wire crimping tool comprising:
 two arms pivotally connected to each other and each arm having two ends, a handle formed one end of the arm and a jaw formed on the other end of the arm; and   an adjustable wire crimping device mounted on the jaws of the arms and comprising
 a duel crimping cavity defined in a first one of the jaws and aligning with a second one of the jaws, wherein the crimping cavity comprises
 an upper segment with a bottom and a lower segment; and 
 the lower segment is defined in the bottom of the upper segment and has a diameter smaller than that of the upper segment; and 
 
 a threaded extension member adjustably mounted in the second jaw and having a crimping tip extending out of the second jaw and aligning with and extending into the duel crimping cavity. 
   
   
   
       2 . The wire crimping tool as claimed in  claim 1 , wherein
 the second jaw has
 a threaded through hole defined through the second jaw and aligning with the duel crimping cavity; and 
 a positioning threaded hole defined in a side of the second jaw and communicating with the threaded through hole; 
   the threaded extension member is mounted in the through hole in the second jaw; and   a lock screw is screwed into the positioning threaded hole and has an end abutting against the threaded extension member to hold the threaded extension member in position.   
   
   
       3 . The wire crimping tool as claimed in  claim 2 , wherein each jaw is C-shaped to define a space between the jaws. 
   
   
       4 . The wire crimping tool as claimed in  claim 3 , wherein the jaws each have a cutting end facing and selectively abutting against with each other; and
 the cutting end of each jaw has a triangular section to form a sharp tip on the cutting end for cutting and stripping insulated wires.   
   
   
       5 . The wire crimping tool as claimed in  claim 4 , wherein each arm further has a plate formed on the handle of the arm having an edge and corresponding to and selectively abutting with the plate on the other arm; and
 a stripping device is mounted between the edges of the plates on the arms and comprises multiple stripping holes defined in and along the edges of the plates and having diameters different from each other.   
   
   
       6 . The wire crimping tool as claimed in  claim 5 , wherein a crimping device is mounted between the edges of the plates on the arms and comprises
 a recess defined in the edge of the plate on a first one of the arms; and   at least one crimping edge formed on the edge of the plate on a second one of the arms and aligning with the recess in the first arm.   
   
   
       7 . The wire crimping tool as claimed in  claim 6 , wherein each arm has a coat made of an insulating material mounted around the handle. 
   
   
       8 . The wire crimping tool as claimed in  claim 1 , wherein each jaw is C-shaped to define a space between the jaws. 
   
   
       9 . The wire crimping tool as claimed in  claim 8 , wherein the jaws each have a cutting end facing and selectively abutting against with each other; and
 the cutting end of each jaw has a triangular section to form a sharp tip on the cutting end for cutting and stripping insulated wires.   
   
   
       10 . The wire crimping tool as claimed in  claim 1 , wherein each arm further has a plate formed on the handle of the arm, having an edge and corresponding to and selectively abutting with the plate on the other arm; and
 a stripping device is mounted between the edges of the plates on the arms and comprises multiple stripping holes defined in and along the edges of the plates and having diameters different from each other.   
   
   
       11 . The wire crimping tool as claimed in  claim 10 , wherein a crimping device is mounted between the edges of the plates on the arms and comprises
 a recess defined in the edge of the plate on a first one of the arms; and   at least one crimping edge formed on the edge of the plate on a second one of the arms and aligning with the recess in the first arm.   
   
   
       12 . The wire crimping tool as claimed in  claim 10 , wherein a wire cutter is mounted between the edges of the plates on the arms and comprises a cutting edge defined in the edge of one of the plates for cutting a wire with a desired length. 
   
   
       13 . The wire crimping tool as claimed in  claim 1 , wherein each arm has a coat made of an insulating material mounted around the handle.
