Abstract

Abstract A crimping tool has identical stamped and formed second class levers which are pivotally joined at their first ends so that a pair of pliers or the like may be used to apply compression force at the opposite free ends to cause the levers to pivot toward each other. The levers respectively have aligned, intermediate portions which include at least one pair of dies in their opposed faces for crimping a terminal to a wire when compression force is applied at the free ends. The first ends are in over-lapping side-by-side relationship with respective coaxially aligned holes extending therethrough to receive a pin about which the levers pivot. The free ends are respectively misaligned and include overlapping alignment tabs so that when the tool is oriented with respect to the pliers in any position which will cause the levers to pivot toward each other, the compression forces are resolved in a direction to produce sliding contact between the tabs and the free ends to maintain the intermediate portions of the tool in alignment throughout crimping.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 370 words
An improved crimping tool of a type having a pair of second class levers stamped and formed from a sheet of metal, said pair of levers being joined at their first ends for relative pivotal movement, each of said levers having an opposite free end at which a compression-exerting tool applies force to said levers to cause them to pivot toward each other, said levers having aligned intermediate portions movable in a first plane which longitudinally bisects each of said intermediate portions, said intermediate portions having at least one pair of dies in opposed faces of said intermEdiate portions, said pair of dies capable of receiving a termianl herein for crimping said terminal to a wire by an application of said force with said compression-exerting tool, which improvement comprises: said first ends of said levers disposed in overlapping side-byside relationship to define a second plane therebetween, said second plane being generally parallel with said first plane, each of said first ends having a hole extending therethrough which said holes are coaxially aligned and disposed generally perpendicularly with respect to said second plane; fastening means extending through said holes for pivotally joining said first ends of said levers; said free ends of said levers disposed generally parallel to each other and displaced one from the other at opposite sides of a third plane defined therebetween, said third plane being generally parallel to said first and second planes; and at least one of said free ends having an integral alignment tab extending coplanarly therefrom, said tab being disposed in over-lapping sliding contact with the other of said free ends along said thrid plane, whereby said displacement of said free ends allows said crimping tool to be oriented with respect to said compression-exerting tool in any position at which said compression-exerting tool forces said levers toward each other and thereby causes said application of said force on said free ends to be in a direction to intersect said third plane at a small acute angle with respect to said third plane and each of said free ends to be respectively forced toward said third plane to cause said integral alignment tab to maintain said intermediate portions in alignment during crimping of said terminal.
Claim 2
Dependent Claim 370 words
An improved crimping tool of a type having a pair of second class levers stamped and formed from a sheet of metal, said pair of levers being joined at their first ends for relative pivotal movement, each of said levers having an opposite free end at which a compression-exerting tool applies force to said levers to cause them to pivot toward each other, said levers having aligned intermediate portions movable in a first plane which longitudinally bisects each of said intermediate portions, said intermediate portions having at least one pair of dies in opposed faces of said intermEdiate portions, said pair of dies capable of receiving a termianl herein for crimping said terminal to a wire by an application of said force with said compression-exerting tool, which improvement comprises: said first ends of said levers disposed in overlapping side-byside relationship to define a second plane therebetween, said second plane being generally parallel with said first plane, each of said first ends having a hole extending therethrough which said holes are coaxially aligned and disposed generally perpendicularly with respect to said second plane; fastening means extending through said holes for pivotally joining said first ends of said levers; said free ends of said levers disposed generally parallel to each other and displaced one from the other at opposite sides of a third plane defined therebetween, said third plane being generally parallel to said first and second planes; and at least one of said free ends having an integral alignment tab extending coplanarly therefrom, said tab being disposed in over-lapping sliding contact with the other of said free ends along said thrid plane, whereby said displacement of said free ends allows said crimping tool to be oriented with respect to said compression-exerting tool in any position at which said compression-exerting tool forces said levers toward each other and thereby causes said application of said force on said free ends to be in a direction to intersect said third plane at a small acute angle with respect to said third plane and each of said free ends to be respectively forced toward said third plane to cause said integral alignment tab to maintain said intermediate portions in alignment during crimping of said terminal.
Claim 3
Dependent Claim 19 words
A crimping tool as set forth in claim 1, wherein said first, second and third planes are generally coplanar.
Claim 4
Dependent Claim 34 words
A crimping tool as set forth in claim 2, wherein: said first end and said free end of a first of said pair of levers are disposed at one side of said first plane.
Claim 5
Dependent Claim 45 words
A crimping tool as set forth in claim 3, wherein: each of said free ends includes said integral alignment tab and each of said tabs is disposed for said overlapping sliding contact with said tab of said other free end and said other free end.
Claim 6
Dependent Claim 27 words
A crimping tool as set forth in claim 4, wherein: said first of said pair of levers is identical to a second of said pair of levers.
Claim 7
Dependent Claim 34 words
A crimping tool as set forth in claim 2, wherein: said first end and said free end of a first of said pair of levers are disposed at opposite sides of said first plane.
Claim 8
Dependent Claim 45 words
A crimping tool as set forth in claim 6, wherein: each of said free ends includes said integral alignment tab and each of said tabs is disposed for said overlapping sliding contact with said tab of said other free end and said other free end.
Claim 9
Dependent Claim 27 words
A crimping tool as set forth in claim 7, wherein: said first of said pair of levers is identical to a second of said pair of levers.
