A support for an elevator car in an elevator installation includes a plurality of tensile carriers, arranged parallel to one another, and a casing. The tensile carriers are enclosed by the casing, wherein the tensile carriers extend along a longitudinal axis of the support. The tensile carriers are freed at least partly from the casing on a section of the longitudinal axis of the support. Contact elements for electrical contacting of the exposed tensile carriers are fastened to the tensile carriers at this section.

Monitoring of support in elevator installations

The invention relates to an electrical plug connector including a plug and a coupling in which radially spring elastic annular contact lamellas are arranged. In order to prevent corrosion when the plug and the coupling are made from different materials the invention proposes a tin plated bushing in the coupling in which bushing the contact lamellas are arranged.

Electrical plug connector

The invention relates to an electrical plug connector including a pin-shaped plug and a sleeve-shaped coupling which encloses the plug with an intermediary cavity and open washer shaped spring elastic contact elements which are arranged in the cavity. In order to provide a good electrical contact the invention proposes two inward protruding knobs of the contact elements, wherein the knobs are arranged opposite to one another. Outward protruding knobs limit a maximum deformation of the contact elements and thus prevent a mechanical overload of the contact elements.

Electrical plug connector having a contact element with inwardly and outwardly protruding knobs

The invention concerns a plug connector for establishing a contact between an electrical component and a conductor bar of a lead frame (not shown). The plug connector has a lamellae packet with contact lamellae into whose slot the electrical conductor can be inserted. The invention proposes to place a spacer lamella between each two adjacent contact lamellae that would limit the insertion depth of the electrical conductor in the slot and would hold the electrical conductor in the slot between the contact springs by means of barbs.

Plug connector

The invention relates to a central electric system for a motor vehicle, having at least two pressed screens arranged parallel to one another with a distance between them, said pressed screens having web conductors formed by punching. For simple manufacture of the central electric system, the disclosure proposes that each pressed screens be extrusion coated with a holding frame of plastic; then the web conductors that are connected to one another at separation points are separated from one another; terminal contacts are bent at a right angle so they project away; the holding frames are assembled, and bent sections of web conductors of a pressed screen, cropped as web conductor connectors, are electrically connected to web conductors of another pressed screen e.g., by ultrasonic welding. The disclosure makes it possible to manufacture central electric systems with complex wiring and cabling with a few pressed screens by a simple method.
