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.

Plug-and-socket connector with screw-type connection

A cable connector includes a core receiving part and a contact carrier joined by a connecting part. The core receiving part houses one or more cores of a cable. The contact carrier is provided with at least one contact element. By means of the connecting part, the core of the receiving part is held in electrical contact with the content element of the contact carrier.

Cable connector

A cable clamp ( ) for clamping cable ( ) in a tubular cable feed-through part ( ) that has a pressure piece ( ) comprised of two pressure rings ( ) with a clamping spring ring ( ) positioned between the two pressure rings ( ) to encircle the cable ( ). The pressure rings ( ) are interconnected so that they are movable with respect to each other in an axial direction over a distance permitting the clamping spring ring ( ) to have an inner diameter equal or somewhat greater than the outside diameter of the cable ( ) or compressed so as to have an inner diameter that is less than the outside diameter of cable ( ).

Cable clamp

A connecting device ( ) for electrically connecting to at least two electrical conductors ( ) in a housing ( ) having a tubular connecting plug ( ), with a contact holder ( ) in the tubular connecting plug ( ), the contact holder ( ) having contact elements ( ) passed through recesses ( ) in conductor holders ( ) to make contact with the conductors. The connecting device ( ) can be expanded into an array of connecting networks with, for example, plug-in connectors, cable bolted assemblies and connecting elements.

Connecting device

In the case of a housing seal (,) for cable through-duct apertures that can be inserted into receptacles (,) for the cable through-duct apertures, whereby housing seal (,) has at least two sealing areas (,or,) with different sealing contours and can be inserted into receptacles (,) in different directions as desired, a low overall height and the use of the housing seal with the same shape for the inlet and outlet apertures of a housing are possible even when asymmetrically profiled cables are used if two sealing areas (,or,) are provided on adjacent sides of housing seal (,), whereby one side points in the direction of the cable through-duct.
