Method and device for compressing a cylindrical sleeve for wire strand

Abstract

[Problems]Present invention develops and provides a stranded wire cylindrical sleeve compression method and compression device, which fits together and inserts a conventional cylindrical sleeve onto a stranded wire, and, matching the outer circumference of the sleeve to the outer circumferential surface of stranded wire, compresses the cylindrical sleeve. [Means to Solve the Problem]As a means for solving this problem, the compressor in the present invention is provided with a pair of handles, and a pair of jaws operated by said pair of handles, and a center portion of said pair of jaws being provided with a plurality of types of pairs of compression portions having a predetermined width and matching the cross-sectional outer circumferential shape of a stranded wire so as to be used for a plurality of cylindrical sleeve sizes, and with a use of the compression portion of said compression device, compressing the entire outer circumference of the cylindrical sleeve, to fully close a gap between the stranded wire and the cylindrical sleeve for full contact with each other, thus providing an increased contact surface area between the wire and the sleeve.

1 . A stranded wire and cylindrical sleeve compression method, characterized by the fact that: when a stranded wire to be connected to a terminal insertion connecting portion of a power meter or a switch, etc. is compressed via a cylindrical sleeve (S), said stranded wire (SL) is pinched and compressed with an intersecting compression device ( 1 ) formed by opposing compression grooves that match the cross-sectional outer circumferential shape of the stranded wire (SL), compressing and securing the stranded wire (SL) and the sleeve (S).  
   
   
       2 . In a compression device for a cylindrical sleeve (S) for a stranded wire to be connected to terminal insertion connecting portions of a power meter or a switch, etc., said compression device ( 1 ) being characterized by being provided with a pair of handles ( 2 ), and being provided with a pair of jaws ( 3 ) operated by said pair of handles ( 2 ), and having a center portion of said pair of jaws ( 3 ) being provided with a plurality of types of pairs of compression portions ( 4 ) having a predetermined width (W) and matching a stranded wire (SL) cross-sectional outer circumferential shape so as to be used for a plurality of cylindrical sleeve (S) sizes, and with a use of the compression portion ( 4 ) of said compression device ( 1 ), compressing the entire outer circumference of the cylindrical sleeve (S), to fully close a gap between the stranded wire (SL) and the cylindrical sleeve (S) for full contact with each other, thus providing an increased contact surface area between the wire and the sleeve.
