Anschlußkralle für elektrische FlachleiterConnection claw for electrical flat conductors

Die Neuerung bezieht sich auf eine Anschlußkralle für elektrische Flachleiter eines Bandkabels, die aus einem Blechstanzteil gebildet ist und einen flachen Boden besitzt, an dessen Längs— rändern sich nach oben gebogene Seitenschenkel anschließen und der Kralle einen U-förmigen Querschnitt verleihene The innovation relates to a connecting claw for electrical flat conductors of a ribbon cable, which is formed from a stamped sheet metal part and has a flat bottom, at the longitudinal edges of which upwardly curved side legs adjoin and give the claw a U-shaped cross-section e

Eine bekannte Anschlußkralle besitzt abgebogene Zähne, die die Leiterisolierung durchdringen und für eine ausreichende Kontaktierung sorgen sollen. Die Zähne, »eiche beim Aufbringen des Anschlußelements durch die oberhalb des Flachleiters befindliche Isolation hindurchgreifen und dann umgebogen werden, bewirken
zum einen die Verbindung zwischen dem isolierten Flachleiter
und dem Anschlußelement und zum anderen die Kontaktgabe» Letztere ist also gleichzeitig in erheblichem Maße von der Verankerung abhängig.A known connecting claw has bent teeth which penetrate the conductor insulation and are intended to ensure adequate contact. The teeth, »which when the connection element is applied, reach through the insulation located above the flat conductor and are then bent over, have the effect
on the one hand the connection between the insulated flat conductor
and the connection element and, on the other hand, the making of contact » The latter is therefore at the same time dependent to a considerable extent on the anchoring.

Der Neuerung liegt die Aufgates zugrunde, eine Anschlußkralle der eingangs genannten Art in bezug auf Festigkeit und Kontaktgabe zu verbessern und die Herstellung zu vereinfachen-The innovation is based on the Aufgates, a connecting claw of the to improve the aforementioned type in terms of strength and contact and to simplify the production.

Diese Aufgabe wird der Neuerung zufolge dadurch gelöst, daß in den flachen Boden zumindest ein sich quer über die Bodenfläche erstreckender prismatischer Grat eingeprägt ist, dessen Scheitel zwischen den Seitenschenkeln liegt. Beim Umkrimpen der Seiteiischenkel, die dann bereits die den Flachleiter beidseitig flankierende Isolierung durchdrangen haben, drücken die freien Enden der Seitenschenkfcl den Flachleiter gegen den relativ spitzen schneidenförmigen Scheitel des prismatischen Grates· Dabei durchdringen sowohl die Enden der Seitenschenkel als auch gegenüberliegend die Gratspitze beidseitig des Flachleiters die Isolierung und bewirken damit eine zuverlässige Kontaktierung der miteinander verbundenen Teile. Durch die Querausrichtung des prismatischen Grate» ist die se geschaffene elektrische Kontaktverbindung auch relativ unempfindlich gegen Zugbeanspruchungen,According to the innovation, this object is achieved in that at least one extends across the floor surface in the flat floor extending prismatic ridge is embossed, the apex of which lies between the side legs. When crimping the side legs, which then have already penetrated the insulation flanking the flat conductor on both sides, press the free ends the side leg penetrate the flat conductor against the relatively pointed, blade-shaped apex of the prismatic ridge · thereby penetrate both the ends of the side legs and the opposite edge of the ridge on both sides of the flat conductor provide the insulation and thus cause reliable contact to be made between the parts connected to one another. Due to the transverse alignment of the prismatic Burrs »is this electrical contact connection that is created also relatively insensitive to tensile loads,

Nach einem »eiteren Merkmal der Neuerung kann vorgesehen sein, daß die freien Enden der Seitenscheitel, die zur Durchdringung der zwischen dem anzuschließenden riachieiter und den benachbarten Flachleitern liegenden Isolation und nach dem Einrollen bzw« Krimpen zur Kontaktierung bestimmt sind, in an sich bekannter Weise eine schneidenförmige Anprägung besitzen· Diese schneidenförmigen Anprägungen können schließlich in Längsrichtung gewellt oder gezackt ausgebildet sein«According to another characteristic of the innovation, it can be provided that the free ends of the side vertices that are used to penetrate the insulation lying between the riachieiter to be connected and the adjacent flat conductors and after rolling or crimps are intended for contacting, have a knife-edge embossing in a manner known per se Knife-shaped embossments can finally be wavy or jagged in the longitudinal direction "

Der Gegenstand der Neuerung wird nachfolgend anhand eines auf der Zeichnung dargestellten Ausführungsbeispiels kurz erläutert, Es zeigenίThe subject of the innovation is briefly explained below using an exemplary embodiment shown in the drawing, Show itί

Es ist zumindest ein prismatischer Grat 31 vorzusehen, jedoch wird die Kontaktsicherheit, sowie auch die Stabilität mit zunehmender Anzahl von prismatischen Graten entscheidend verbessert.Strength, so that relatively thin-walled sheet metal material is used can be. At least one prismatic ridge 31 is to be provided, but the contact security, as well as the stability significantly improved with an increasing number of prismatic ridges.
