Abstract
The present invention relates to crimping pliers in particular used for forming at least three recesses at a contact element housing an electrical conductor. The inventive crimping pliers (1) comprise a toggle lever drive (6). The toggle lever drive (6) is built with an elastic pressure lever (18). The pressure lever (18) is preferably built with an offset or cranking (33) so that with the application of a longitudinal force the pressure lever (18) is biased by a bending. The flexible design of the pressure lever (18) provides a variable crimping stroke (in particular also in connection with a forced locking mechanism (28)) for different dimensions of the contact elements to be crimped.
Claims24
Crimping pliers for crimping a workpiece, the crimping pliers comprising:
- a) a pliers head comprising a base body and an actuation body, wherein the actuation body is movable relative to the base body for causing a crimping movement,
- b) a fixed hand lever fixedly connected to the base body,
- c) a movable hand lever operatively connected to the actuation body, the moveable hand lever comprising a toggle joint,
- d) a pressure lever pivotably linked to the fixed hand lever at a pivot bearing of the fixed hand lever,
- e) wherein the movable hand lever is pivotably linked to the pressure lever via the toggle joint, and
- f) wherein the pressure lever is elastic such that a length of the pressure lever between the toggle joint and the pivot bearing decreases in response to applied hand forces upon the fixed hand lever and the moveable hand lever.
