Abstract:
A coaxial cable end connector for being crimped by axial compression and for use with a coaxial cable having a central conductor, an inner insulation, an outer conductor, and an outer insulation, the coaxial cable end connector comprising:an outer barrel having a bore, a longitudinal axis, and a wall, said wall of said outer barrel having at least one collapsible band extending between a first non-collapsible wall portion and a second non-collapsible wall portion, said collapsible band having an inner side facing toward the longitudinal axis of said outer barrel, said collapsible band having an outer side facing away from the longitudinal axis of said outer barrel, said collapsible band having a bend about midway between said first non-collapsible wall portion and said second non-collapsible wall portion when viewed in cross section, said outer side of said collapsible band having a first portion extending between said bend and said first non-collapsible wall portion, said outer side of said collapsible band having a second portion extending between said bend and said second non-collapsible wall portion, said first portion of said outer side of said collapsible band and said second portion of said outer side of said collapsible band forming an obtuse angle therebetween, said inner side of said collapsible band having a first portion extending between said bend and said first non-collapsible wall portion, said inner side of said collapsible band having a second portion extending between said bend and said second non-collapsible wall portion, said first portion of said inner side of said collapsible band and said second portion of said inner side of said collapsible band forming an obtuse angle therebetween, such that said bend is positioned radially closer to the longitudinal axis of said outer barrel than any other portion of said collapsible band when said collapsible band is viewed in cross section and prior to axial compression of said outer barrel, andan inner tube positioned at least in part within the bore of said outer barrel, said inner tube being coaxial with said outer barrel,said collapsible band forming an annular rib projecting inward toward said inner tube when said outer barrel is axially compressed,to thereby fixedly grip the outer conductor and the outer insulation of the coaxial cable between said outer barrel and said inner tube, and simultaneously frictionally fix said inner tube to the coaxial cable and relative to said outer barrel, when the coaxial cable is inserted into said outer barrel, such that the central conductor and the inner insulation are inserted into said inner tube and the outer conductor and the outer insulation are positioned intermediate said outer barrel and said inner tube, prior to compression of said outer barrel.
