ABSTRACT:
A crimper for crimping cable terminals, cable connectors, and similar materials to electric conductors, optical conductors, etc. has two handles (2 & 7) that can be displaced toward each other and two crimping jaws (3 & 5), whereby one crimping jaw (5) is mounted so that it can move on the other (3). The moving handle (7) is mounted on an articulated support (19) on the moving crimping jaw (5). A toggle-lever drive mechanism consists of a pressure-application arm (8) and of a toggle-lever section (18) on the moving handle, whereby the ratio between lengths is at least approximately 2:1. The closing motion of the toggle-lever drive mechanism is terminated just before the extended state is attained by stops (24 & 25). At least one articulated support (19 or 20) can be displaced to vary the pressure. There is an automatic locking mechanism with a resiliently movable but stationary latch (11) that prevents the crimper from opening before crimping jaws have closed. The latch is mounted on the pressure-application arm and the automatic locking mechanism has a toothed section (14) with a number of teeth (22) rigidly fastened to the moving handle.
