Link for crimping tool

Abstract

The invention relates to a link for a crimping tool (2) comprising at least two crimping dies (12,14,16,18) and two tool handles (6,8), where the movable link (23) is arranged between the tool handles (6,8), the link (23) having an opening (72) arranged to engage a guide element (70) on a first handle (6) and being pivotally fixed to a second handle (8), where the guide element (70) is arranged to move from engagement with a first edge (71) of the opening (72) into engagement with a second opposite edge (73) of the opening (72) when the handles (6,8) are brought together to a position where the workpiece (19) is engaged by the crimping dies (12,14,16,18), the link (23) thus enabling the person using the crimping tool (2) to utilize the optimum gripping range of the hand that is about to exert a large force on the handles (6,8) in order to bring them further together for the crimping of the workpiece (19), this regardless of the dimension of the workpiece (19) to be crimped.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 shows schematically a side view of a crimping tool according to the invention in open position, i.e. before the beginning of the crimping stroke,

FIG. 2 shows the four crimping dies shown in FIG. 1 in an exploded view,

FIG. 3 shows schematically the crimping tool according to FIG. 1 in a closed position, i.e. after the crimping stroke,

FIG. 4 shows schematically the body of the tool,

FIG. 5 shows schematically the cooperation between the tooth flanks on body and die, and

FIG. 6-9 shows the crimping tool according to FIG. 1 without the toothed segment.

Claims

1. Link for crimping tool (2) comprising at least two crimping dies (12,14,16,18) and two tool handles (6,8), characterized in, that the movable link (23) is arranged between the tool handles (6,8), the link (23) having an opening (72) arranged to engage a guide element (70) on a first handle (6) and being pivotally fixed to a second handle (8), where the guide element (70) is arranged to move from engagement with a first edge (71) of the opening (72) into engagement with a second opposite edge (73) of the opening (72) when the handles (6,8) are brought together to a position where the workpiece (19) is engaged by the crimping dies (12,14,16,18), the link (23) thus enabling the person using the crimping tool (2) to utilize the optimum gripping range of the hand that is about to exert a large force on the handles (6,8) in order to bring them further together for the crimping of the workpiece (19), this regardless of the dimension of the workpiece (19) to be crimped.

2. Link according to claim 1, characterized in, that the movable link (23) comprises at least one recess (74,76,78) at the second edge (73) of the opening (72) which recess is arranged for receiving the guide element (70), said recess (74,76,78) corresponding to a workpiece (19) cross-section dimension range.

3. Link according to claim 2, characterized in, that the movable link (23) is arranged to be somewhat elastically deformable thus acting as a spring balancing the forces between the handles (6,8) and the crimping dies (12,14,16,18) when the guide element (70) is in a recess (74,76,78) at the second edge (73) of the opening (72) and the handles (6,8) are brought further together, thus acting as a spring balancing the forces between the handles (6,8) and the crimping dies (12,14,16,18) in order to compensate for different dimensions of the workpiece (19) within said workpiece (19) cross-section dimension range.
