Kind of a contact tulip and are pressed against the contact pieces by individual leaf springs that are supported on a housing. Housing and leaf springs run this practically ψ no electricity. Furthermore, a Hochstront contact device is known for surface contact elements which can be moved relative to one another and in which contact lamellar strips are arranged in grooves in the contact surfaces (DT-OS 1 665 132), as they do

In Fig. 1 ist das stiftförmige Kontaktstück 1 im Bereich seiner Eingriffszone ballig ausgebildet. Das Kontaktstück arbeitet mit einer Vielzahl von Kontaktfingern 2 zusammen, welche innerhalb des stromführenden Gehäuses 3 angeordnet sind. Die Halterung der Kontaktfinger 2 ist so getroffen, dass die Kontaktfinger 2 unverlierbar und nachgiebig gelagert sind. Hierzu besitzt jeder Kontaktfinger 2 an den beiden Enden je einen Zylinderstift 4, welche in Bohrungen von Halteringen 5 eingreifen. Dadurch werden die Kontaktfinger 2 in ihrer Lage lose gehalten. Auf der dem Gehäuse 3 zugekehrten Seite "ist in Nuten 2a des Kontaktfingers 2 das.Kontaktlamellenband gIn Fig. 1, the pin-shaped contact piece 1 is in the area its engagement zone is convex. The contact piece works together with a large number of contact fingers 2, which are arranged within the current-carrying housing 3. The holder of the contact fingers 2 is made so that the Contact fingers 2 are captive and resiliently mounted. For this purpose, each contact finger has 2 at both ends a cylinder pin 4, which in bores of retaining rings 5 intervene. As a result, the contact fingers 2 are held loosely in their position. On the side facing the housing 3 "is das.Kontaktlamellenband g in grooves 2a of the contact finger 2

reibungsschlüssig und federnd eingesetzt, durch welches die Stromübertragung auf das Gehäuse 3 erfolgt. Die Zylinder-■ stifte l.i haben zugleich die Aufgabe, den Federweg des Kontaktlamellenbandes 6 zu begrenzen. Bei eingestecktem Kontaktstück 1 werden die Kontaktfinger 2 nach aussen gedrückt, wobei die Kontaktlamellenbänder 6 den für den Stromübergang nötigen , Kontaktdruck zwischen dem Gehäuse 3 und den Kontaktfingern 2. % einerseits, und zwischen den Kontaktfingern und dem Kontaktstück 1 andererseits, erzeugen. Der Sprengring 7 hält das System Kontaktfinger/Halteringe im Gehäuse 3. Wie Fig. 2 deutlich zeigt, kann der einzelne Kontaktfinger 2 in vorteilhafter Weise durch Abschneiden von einem gezogenen Kupfer— profil hergestellt sein, wobei das Kontaktlamellcnband 6 als ein auf entsprechende Länge geschnittenes Bandstück, das mit seinen Rändern in die Nuten 2a eingreift, aufgeschoben ist.Frictionally and resiliently used, through which the current is transmitted to the housing 3. The cylinder pins l .i also have the task of limiting the spring travel of the contact lamellar strip 6. When the contact piece 1 is inserted, the contact fingers 2 are pressed outwards, the contact lamellar strips 6 generating the contact pressure required for the current transfer between the housing 3 and the contact fingers 2% on the one hand, and between the contact fingers and the contact piece 1 on the other. The snap ring 7 holds the contact finger / retaining ring system in the housing 3. As FIG. 2 clearly shows, the individual contact finger 2 can advantageously be produced by cutting off a drawn copper profile, the contact lamella strip 6 being a piece of tape cut to the appropriate length , which engages with its edges in the grooves 2a, is pushed.
ψ Die neue Kontaktvorrichtung kann unter Stromlast achsial und radial wirkende Kräfte aufnehmen und lässt achsiale Verschiebungen zu. Wenn die Halteringe 5 im Gehäuse 3 entsprechend gesichert sind, kann die Kontaktvorrichtung auch Drehbewegungen vertragen. Ein weiterer Vorteil ist die billige und. raumsparende Bauweise. ψ The new contact device can absorb axially and radially acting forces under current load and allows axial displacements. If the retaining rings 5 are appropriately secured in the housing 3, the contact device can also tolerate rotary movements. Another advantage is the cheap and. space-saving construction.
