Abstract
Abstract A shunt (20) for electrically joining terminal posts (12) each having a width (W) comprises a base (22) which is apertured (23) to freely receive the posts (12) therethrough, and arms (26) extending upwardly from opposite sides of the base (22) and converging to a constriction (28) between free ends (18) thereof. A dimension (D) of the constriction (28) is less than the width of the posts (12), whereby the posts may be captured between the free ends (18). The base (22) has ears (24) at opposite ends which extend beyond side edges (27) of the arms (26) and are adapted to be engaged by the tool (30). The tool comprises a body (32) and a separator (34) extending from the body. The separator (34) has a width (S) which is greater than the constriction dimension (D) but less than the width (W) of the posts. The separator (34) is insertable in the constriction (28) to resiliently deflect the arms (26) and thereby become engaged between the free ends (18) to frictionally retain the shunt (20) to the tool (30). An inserter (36) extending from the body substantially parallel to the separator (34) is arranged such that, when the separator (34) is engaged between the free ends (18), a leading end (37) of the inserter is engageable against the base (22) without the inserter (36) being engaged between the free ends (18).

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
226 words
A tool for installing an electrical shunt on terminal posts each having a width, the shunt having a base which is apertured to freely receive the posts therethrough, and arms extending upwardly from opposite sides of the base and converging to a constriction between free ends thereof, a dimension of the constriction being less than the width of the posts wherein the posts may be captured between the free ends, the tool comprising: a body; a separator extending from the body, the separator having a width which is greater than the constriction dimension but less than the width of the posts, the separator being insertable in the constriction to resiliently deflect the arms and thereby become engaged between the free ends to frictionally retain the shunt to the tool; and, an inserter extending from the body substantially parallel to the separator and arranged such that, when the separator is engaged between the free ends, a leading end of the inserter is engageable against the base without the inserter being engaged between the free ends; wherein the posts may be received through the apertured base and the shunt may be urged downwardly by the leading end of the inserter to cause entry and capture of the posts between the free ends, thereby releasing the separator from engagement between the free ends and permitting withdrawal of the tool.
Claim 2
Dependent Claim
226 words
A tool for installing an electrical shunt on terminal posts each having a width, the shunt having a base which is apertured to freely receive the posts therethrough, and arms extending upwardly from opposite sides of the base and converging to a constriction between free ends thereof, a dimension of the constriction being less than the width of the posts wherein the posts may be captured between the free ends, the tool comprising: a body; a separator extending from the body, the separator having a width which is greater than the constriction dimension but less than the width of the posts, the separator being insertable in the constriction to resiliently deflect the arms and thereby become engaged between the free ends to frictionally retain the shunt to the tool; and, an inserter extending from the body substantially parallel to the separator and arranged such that, when the separator is engaged between the free ends, a leading end of the inserter is engageable against the base without the inserter being engaged between the free ends; wherein the posts may be received through the apertured base and the shunt may be urged downwardly by the leading end of the inserter to cause entry and capture of the posts between the free ends, thereby releasing the separator from engagement between the free ends and permitting withdrawal of the tool.
Claim 3
Dependent Claim
17 words
The tool according to claim 1, wherein the separator is insertable between a pair of the posts.
Claim 4
Dependent Claim
30 words
The tool according to claim 2, wherein the inserter comprises a pair of inserter prongs each having a said leading end and disposed on respective opposite sides of the separator.
Claim 5
Dependent Claim
36 words
The tool according to claim 3, wherein said inserter prongs are spaced from the separator such that said pair of posts may each be received between the separator and a respective one of said inserter prongs.
Claim 6
Dependent Claim
21 words
The tool according to claim 4, wherein said inserter prongs are arranged such that they do not extend through the constriction.
