Abstract: A multi-plug insert has a first part which provides a first number of contact inserts. A second part includes a second multiple number of connecting contacts relative to the first number. Each contact insert in the first part is permanently conductively connected to the multiple number of connecting contacts in the second part. The second part, between each two adjoining sets of multiple members of connecting contacts each permanently conductively connected to a contact insert in the first part is provided with an aperture into which it is possible to clamp a contact bridge. The contact bridge establishes a conducting connection between the two adjoining sets of multiple number of connecting contacts with all the connecting contacts remaining accessible.

Abstract: In crimping pliers for connecting contact elements to electrical conductors, which crimping pliers consist of a grip, a retaining plate, which is fixed to the latter and has a lateral recess accommodating the contact elements, on the upper side of which recess cutouts are made which interact with the crimping stamps which project at the upper side from a workplate displaceably guided in the retaining plate, on which workplate a hand lever is pivoted, the tightening movement of which displaces the workplate relative to the retaining plate and moves the crimping stamps into the open cutouts, a housing is fixed to the workplate in order to automatically feed a sheet-metal strip, which supports contact elements at intervals and has mating holes, and a linkage mechanism is pivoted on the hand lever.
