An insulation body for an electrical connector unit includes at least two insertion channels into each of which a contact pin or a contact bush can be inserted, which preferably are aligned parallel to a main axis of the insulating body into which a securing channel empties, preferably perpendicular to it, in which a set screw is supported so as to turn, by means of which the related contact pin or the related contact bush can be mechanically impinged on, and to which an insulating collar is assigned, which is arranged on the outer side of the insulating body, at least approximately coaxial to the related securing channel. Preferably each of the insulating collars has at least one collar opening that is limited on both sides by collar ends.

Insulating body for an electrical plug connection unit

The connector includes an electrically insulating one-part or multi-part housing, in which at least one contact element is arranged, which is accessible via a first opening of the housing by a contact element of a complimentary second connector, and which is connectable with an electrical cable that can be introduced through a second opening of the housing. The housing of the assembled connector, which is made from a first material, includes at least a first coupling element, which corresponds to at least one second coupling element that is included on a tubular element, which is manufactured from a second material which after processing includes a higher mechanical strength than the first material, and wherein the housing is releasably held within the tubular element by the releasably interlinked coupling elements.

Connector

The invention relates to a plug connector having a main part, comprising a contact blade basket or skirt having at least one first and one second contact zone. Said contact zones are disposed one after the other in the longitudinal direction of the plug connector and have a plurality of contact blades. Adjacent contact blades are separated from each other by a gap. An intermediate wall is provided between the contact zones disposed one after the other, forming a conductive contact both between the contact blades of the first contact zone and the contact blades of the second contact and between the individual contact blades of the first contact zone and the individual contact blades of the second contact zone.

Electrical plug connector

An improved electrical plug-and-socket connectors with screw-type clamping connections has a step-shaped screw brake for protecting against loss of the clamping screw of connecting stranded conductors of electrical components having as the clamping mode a screw-type clamping connection. The screw brake has one, two or more strips. The plug-and-socket connector has a screw-type connection, having an insulating part, arranged to accommodate at least one contact insert. The contact insert has a substantially cylindrical shape and comprises a contact portion for electrical/mechanical connection to an oppositely shaped contact piece of a matched plug-and-socket connector at a first end of the contact insert. It further comprises an insertion opening for at least one connecting stranded conductor at a second end of the contact insert, there opening in the insertion opening a screw hole which is oriented substantially transversely relative to the central longitudinal axis thereof and comprises an internal thread. The insulating part has a screw channel which is substantially in alignment with the screw hole when a contact insert is accommodated in the insulating part. The screw channel has at least one step. The inside width of the screw channel reduces from a first, greater dimension towards a second, lesser dimension in the direction towards the screw hole of the insertion opening. The screw channel has one or more strips which are oriented substantially coaxially relative to its central longitudinal axis of the and which are so dimensioned that a clamping screw to be inserted in the screw channel fastening the connecting stranded conductor in the insertion opening of the contact insert is subjected to a first, lesser resistance at the strip/strips of the first inside width, and is subjected to a second, greater resistance at the strip/strips of the second inside width.
