Crimping Tool

a technology of crimping tool and crimping die, which is applied in the direction of stripping off devices, basic electric elements, electrical equipment, etc., can solve the problems of work piece breaking free from the crimping contour, and achieve the reduction of the geometrical moment of inertia, the effect of avoiding the deformation of the crimping contour, and reducing the force required for removing the work piece from the crimping die halves

Abstract

The present invention relates to a crimping tool, in particular crimping pliers. The crimping tool comprises crimping die halves having a resilient deformation region. At the end of a crimping process the resilient deformation region is elastically deformed with the result that the crimping contour opens and contour parts automatically move apart. Accordingly, the crimping contour “breaks free” from the work piece for an ease of the removal of the work piece from the crimping tool.

Description

CROSS REFERENCE TO RELATED APPLICATIONS

[0001] This application claims priority to co-pending German Patent Application No. DE 10 2009 001 949.9 entitled “Gesenkhalfte and Presswerkzeug”, filed Mar. 27, 2009.FIELD OF THE INVENTION

[0002] The present invention generally relates to a crimping tool which might be driven by hand or by a hydraulic, an electrical or any other drive and which is used for crimping a work piece. Without restricting the invention to the following examples, the work piece might be a fitting for connecting tubes or conduits, a cable shoe, a sleeve for an end of a cable, a plug, a crimp connection without lead, a double connection for a wire and an insulation of the wire, a socket or a connecting element for an electrical cable or an optical fiber cable.BACKGROUND OF THE INVENTION

[0003] When using crimping tools, it might happen that the work piece keeps attached or sticks to the crimping contour of the crimping die halves at the end of the crimping process. To remov...

Embodiment Construction

[0037]The invention relates to a crimping tool, in particular crimping pliers 1, with any drive mechanism, in particular manually activated hand levers or an electric or hydraulic drive. The crimping pliers 1 (besides the inventive features described in the following) might have any design or construction known from prior art. In particular, the crimping pliers 1 might have activation mechanisms, a force locking unit, a locator or a head of the pliers or other constructive details known from crimping pliers distributed by the present applicant, in particular known from documents U.S. Pat. No. 4,794,780, U.S. Pat. No. 5,153,984, EP 0 471 977 B1, U.S. Pat. No. 5,187,968, DE 44 27 553 C2, U.S. Pat. No. 5,913,933, DE 197 09 639 A1, DE 197 53 436 C2, U.S. Pat. No. 6,053,025, U.S. Pat.
