The invention relates in general to a cutting and clamping sleeve contact for contacting a cable core transversely to the sleeve axis, and in particular for cable cores of the telecommunication technology. The contact is made of a metal sleeve shell and includes a clamping slot for the insulated cable core and a cutting and clamping contact slot within the sleeve for the stripless termination of the cable core. The present invention also relates to a method for producing the cutting and clamping sleeve contact. A portion 13 of a sleeve shell 12 is bent off radially into an interior of the sleeve body 12 and is provided with a cutting/clamping contact slot 2. A clamping slot 3 is opposite to the cutting/clamping contact slot 2 and is cut into the sleeve shell 15. The present invention improves the cutting and clamping sleeve contact, with regard to the independence of the cutting/clamping slot 2 from the movements at the clamping slot 3, and with regard to the observation of accurate tolerances.

Cutting and clamping sleeve contact

The invention relates to a connector bank for telecommunication systems comprising connecting elements 4, 25, 26 for cable wires and comprising contact elements 10 for electrical connection of the connecting elements 4, 25, 26 with the circuit tracks of a printed-circuit board 20. The arrangement prevents damage due to connecting forces which are otherwise transferred to the contact elements when connecting the cable wires to the connecting elements 4, 25, 26. According to the invention the contact elements 10 are provided as separate components of a contact pin 11 and of a plug connector member 12 being formed as one piece therewith for connection with the connecting elements 4, 25, 26.

Connector bank for telecommunication systems

The invention relates to a cutting/clamping contact (1) for contacting an insulated cable core (5), comprising two contact legs (2, 3) made of a blade-type, resilient metal material, between the inner sides (13, 14; 23, 24) of which an upwardly open contact slot (4) with an enlarged wire introduction section (7) is formed. In order to provide a cutting/clamping contact (1) which allows for contacting cable cores (5) having a thick insulation (6) as well as cable cores having a thin conductive core (12), in particular with a ratio of insulation to conductive core diameter larger than 3, the inner side (13, 14; 23, 24) of at least one contact leg (2, 3) comprises, in the wire introduction section (7) an inclined surface (8, 9) forming a cutting edge (10) directed into the wire introduction section (10).
