Abstract
A crimping tool for connecting a cable fitting to the end of a coaxial cable is made up of one or more die members having tapered die surfaces of circular configuration, a chuck which is axially spaced from the die surfaces to support the fitting in loosely assembled relation to the end of the cable, and a handle is pivotally mounted in such a way as to cause axial movement of the chuck toward and away from the die surfaces and specifically to axially force the fitting into the die cavity and uniformly reduce the circumference of one end of the fitting into a generally conical configuration snugly engaging the cable.
Claims20
A crimping device for connecting a cable fitting having a generally tubular connector sleeve to an end of a coaxial cable wherein said sleeve is composed of a thin-walled deformable material, said device comprising:
- a die member defining a tapered cavity having a first diameter at a first end thereof substantially corresponding to an outer diameter of said sleeve and a second diameter axially spaced from said first diameter which substantially corresponds to an outer diameter of said cable end;
- carrier means axially spaced from said cavity for supporting said sleeve in facing relation to said first end of said cavity with said cable end extending through said cavity and at least partially inserted into said sleeve;
- and
- support means mounting said carrier for axial movement toward and away from said die member whereby to force said sleeve axially into said cavity under sufficient force to radially contract said sleeve into a tapered configuration conforming with said tapered cavity of said die to thereby connect said sleeve to said end of said cable.
A portable crimping tool for connecting a cable fitting having a generally tubular connector sleeve to an end of a coaxial cable wherein said sleeve is composed of a thin-walled deformable material, said tool comprising:
- a die member defining a tapered cavity having a first diameter at a first end thereof corresponding to an inner diameter of said sleeve and a second diameter axially spaced from said first diameter which corresponds to an outer diameter of said cable end;
- a chuck member axially spaced from said cavity, said sleeve disposed on one end of said chuck in alignment with said first end of said cavity with said cable end extending through said cavity and at least partially inserted into said sleeve;
- a pivotal handle;
- and
- support means pivotally mounting said pivotal handle for axial movement of said chuck member toward and away from said die whereby to force said sleeve axially into said cavity under sufficient force to uniformly reduce a circumferential portion of said sleeve into a generally conical configuration conforming with said tapered cavity of said die snugly engaging said end of said cable.
A crimping device for connecting a cable fitting having a generally tubular connector sleeve to an end of a coaxial cable wherein said sleeve is composed of a thin-walled deformable material, said device comprising:
- a die member defining a tapered cavity having a first diameter at a first end thereof substantially corresponding to an outer diameter of said sleeve and a second diameter axially spaced from said first diameter which substantially corresponds to an outer diameter of said cable end, said die member having segmental die portions defining circumferential portions of said cavity, at least one of said die portions being movable into and out of circumferential alignment with the other of said die portion, pivot means for pivoting said one die portion into and out of circumferential alignment with said other of said die portions including a lever arm having a cam member engageable with said one die portion in advancing said one die portion into circumferential alignment with said other die portion;
- carrier means axially spaced from said cavity for supporting said sleeve in facing relation to said first end of said cavity with said cable end extending through said cavity and at least partially inserted into said sleeve;
- and
- support means mounting said carrier for axial movement toward and away from said die member whereby to force said sleeve axially into said cavity under sufficient force to radially contract said sleeve into a tapered configuration conforming with said tapered cavity of said die to thereby connect said sleeve to said end of said cable.
