Coaxial cable stripper

Abstract

A coaxial cable stripper, consisting of:—a cutting unit ( 1 ) comprising cutting means ( 7 ) for a plurality of sheaths, said cutting unit ( 1 ) being designed to surround a cable ( 5 ) and cut its sheaths simultaneously by rotation of said cutting means ( 7 ) about the cable ( 5 ),—an intermediate unit ( 2 ) designed to surround said cable ( 5 ) and comprising means ( 6, 29 - 31 ) for adjusting the rotation of said cutting means ( 7 ),—a fixing unit ( 3 ) comprising fixing means ( 8 ) for said cable ( 5 ), the three units ( 1 - 3 ) being adjacent to one another and aligned along a common axis defined by said cable ( 5 ).

1 . A coaxial cable stripper, consisting of: 
 a cutting unit ( 1 ) comprising cutting means ( 7 ) for a plurality of sheaths, said cutting unit ( 1 ) being designed to surround a cable ( 5 ) and cut its sheaths simultaneously by rotation of said cutting means ( 7 ) about the cable ( 5 ),    an intermediate unit ( 2 ) designed to surround said cable ( 5 ) and comprising means ( 6 ,  24 ,  29 - 32 ) of adjusting the rotation of said cutting means ( 7 ),    a fixing unit ( 3 ) comprising fixing means ( 8 ) for said cable ( 5 ),    the three units ( 1 - 3 ) being adjacent to one another and aligned along a common axis defined by said cable    said stripper being characterized in that:    the cutting unit ( 1 ) consists of a cylindrical housing ( 9 ) which is open on that side of its base ( 10 ) which is in contact with the intermediate unit ( 2 ), the inside of the housing ( 9 ) consisting of at least:    a) two rotary cutting disks ( 11 - 13 ) comprising an opening ( 14 ) in their center for passage of the cable ( 5 ), the face ( 15 ) of each rotary disk ( 11 - 13 ) which is opposite the intermediate unit ( 2 ) consisting of a swivel blade ( 7 ) designed to cut the sheaths of the cable ( 5 ), the other face ( 16 ) consisting of means ( 18 ) for fixedly connecting with the adjacent disk ( 11 - 13 ,  19 ) and means ( 17 ) for pivoting the blade ( 7 ),    b) a rotary guide disk ( 19 ) comprising guide means ( 20 ,  21 ) for said blades ( 7 ), said guide disk ( 19 ) being fixedly connected to the cutting disk ( 11 ) which is adjacent thereto by means of said connecting means ( 18 ),    the back of the housing ( 22 ) additionally consisting of driving means ( 18 ) for the rotary cutting disk ( 13 ) which is adjacent thereto;    the intermediate unit ( 2 ) being fixedly connected to the fixing unit ( 3 ).    
     
     
         2 . The stripper as claimed in the preceding claim, characterized in that that side ( 15 ) of a rotary cutting disk ( 11 - 13 ) which consists of the swivel blade ( 7 ) also consists of means ( 25 ) for adjusting the positioning of the connecting means ( 18 ) located on the face ( 16 ) of the adjacent disk, this in order to allow an adjustment of the cutting depth of the blades ( 7 ).  
     
     
         3 . The stripper as claimed in  claim 1  or  2 , characterized in that the rotary guide disk ( 19 ) comprises a cylinder ( 20 ) intended to surround the cable ( 21 ), said cylinder ( 20 ) comprising a series of slots ( 21 ) which are disposed perpendicularly to the direction defined by the cable ( 5 ) and are designed to guide the blades ( 7 ) as they are pivoted.  
     
     
         4 . The stripper as claimed in any one of the preceding claims, characterized in that said connecting means ( 18 ) and said means ( 7 ) for pivoting the blade are pivots disposed perpendicularly to the faces ( 15 ,  16 ) of the disks ( 11 - 13 ), the connecting pivot ( 18 ) entering into contact with a first circular-arc-shaped slot ( 26 ) made on the face ( 15 ) of the opposite disk, the pivot ( 17 ) acting on the blade ( 7 ) entering into contact with a second circular-arc-shaped slot ( 27 ) made on a part of the blade ( 7 ).  
     
     
         5 . The stripper as claimed in any one of the preceding claims, characterized in that the guide disk ( 19 ) also comprises cutting means ( 7 ).  
     
     
         6 . The stripper as claimed in any one of the preceding claims, characterized in that the adjusting means ( 6 ,  29 - 31 ) of the intermediate unit ( 2 ) consist of two disks ( 30 ,  31 ), the first disk ( 31 ) remaining fixedly connected to the assembly formed by the intermediate unit ( 2 ) and the fixing unit ( 3 ), the second disk ( 30 ) being designed to rotate about the cable ( 5 ) whilst exerting friction upon the first disk ( 31 ).  
     
     
         7 . Method of use of a stripper according to any one of the claims, characterized in that a rotation in one direction of the cutting unit ( 1 ) results in the blade ( 7 ) being moved toward the sheath to be cut and in that an oppositely directed rotation results in the blade ( 7 ) being moved further away from the sheath.
