Abstract

The metallic connecting piece (10) having a galvanised surface has a plate (18) and two tongues (20, 21), which are mutually opposite said plate and are folded back with respect to one another in such a manner that their end edges (22, 23) and the region of the plate (18) adjacent thereto form a groove (24). The insulating wire (30) (lead) which is wound on the connecting piece (10) is located in the obliquely arranged groove (24). Subsequently, the connecting piece (10) and the wire (30) are joined together by means of electrical resistance welding to form an electrical connection.

Stand der TechnikState of the art

Die Erfindung betrifft eine elektrische Verbindung eines Anschlußstücks nach dem Oberbegriff des Anspruchs 1. Eine derartige Verbindung ist aus der DE-PS 6 28 084 bekannt, bei der ein Zurückdrücken der Schweißstelle und ein Abquetschen der Leitung im Schweißbereich praktisch ausgeschlossen sind. Diese technisch günstige Verbindung ist wegen der verhältnismäßig tiefen Rille nur bei Anschlußstücken mit großem Querschnitt durchführbar und bei insbesondere dünnen Flachschienen nicht möglich.The invention relates to an electrical connection of a connector according to the preamble of Claim 1. Such a connection is known from DE-PS 6 28 084, in which a push back of the Welding point and pinching of the cable in the welding area are practically impossible. These Technically favorable connection is only possible with large connectors because of the relatively deep groove Cross-section feasible and not possible with thin flat rails in particular.

Der Erfindung liegt daher die Aufgabe zugrunde, eine elektrische Verbindung zu schaffen mit einem Anschlußstück, das als insbesondere dünnwandige Flachschiene ausgebildet ist. Ausgehend von einer Verbindung der im Oberbegriff des Anspruchs 1 genannten Art wird diese Aufgabe durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst. Dadurch, daß die Rille durch Zurückfalten der beiden Zungen gebildet wird, erreicht man eine doppelte Höhe im kritischen Bereich der Schweißstelle.The invention is therefore based on the object of creating an electrical connection with a connector, which is designed as a particularly thin-walled flat rail. Based on a connection of the im This task is achieved by the characterizing features of the type mentioned in the preamble of claim 1 Claim 1 solved. The fact that the groove is formed by folding back the two tongues is achieved double the height in the critical area of the weld.

Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen beschrieben. Mit der Ausgestaltung der Verbindung nach Anspruch 2 läßt sich vor dem Schweißvorgang das Endstück der Leitung in deren Wickelsinn günstig auf dem Anschlußstück befestigen. Mit Anspruch 3 ist eine Beschädigung der Leitung durch scharfe Kanten ausgeschlossen.Advantageous further developments of the invention are described in the subclaims. With the design the connection according to claim 2 can be the end of the line in their prior to the welding process Attach the winding direction conveniently to the connector. With claim 3 damage to the line is through sharp edges excluded.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und in der Figurenbeschreibung näher erläutert. Es zeigtAn embodiment of the invention is shown in the drawing and in the description of the figures explained in more detail. It shows

F i g. 1 zeigt ein für eine elektrische Verbindung als Flachschiene ausgebildetes metallenes Anschlußstück 10 mit einer verzinnten Oberfläche. Das Anschlußstück hat einen S-förmig abgekröpften Lappen 11 und einen sich einstückig fortsetzenden Schweißbereich 12. Von einer Vorrichtung für das elektrische Widerstandsschweißen sind schematisch angedeutet: Ein Schweißgenerator 14, eine amboßähnliche Festelektrode 15 und eine bewegliche, vorzugsweise ballig geformte Elektrode 16, deren Schweißhub Pfeil 17 versir bildlicht.F i g. 1 shows a metal connector designed as a flat bar for an electrical connection 10 with a tinned surface. The connecting piece has an S-shaped bent tab 11 and one welding area 12 continuing in one piece from a device for electrical resistance welding are indicated schematically: A welding generator 14, an anvil-like fixed electrode 15 and a movable, preferably spherically shaped electrode 16, the welding stroke of which arrow 17 is illustrated.

Die Fig.2 und 3 zeigen vom Anschlußstück 10 abschnittsweise dessen Lappen 11, an dem sich eine Platte 18 anschließt. Eine erste und zweite Zunge 20,21 sind einandergegenüberliegend einstückig an der Platte 18 angeformt und in Abschnitt 20', 21' derart gegeneinander zurückgefaltet, daß die eine und andere Stirnkante 22, 23 mit dem anliegenden Bereich der Platte 18 eine U-förmige Rille 24 bildet.2 and 3 show sections of the connector 10 of the tab 11 on which there is a Plate 18 connects. A first and second tongue 20, 21 are opposite one another in one piece on the plate 18 and folded back against each other in section 20 ', 21' in such a way that one and the other Front edge 22, 23 forms a U-shaped groove 24 with the adjacent area of plate 18.

Die Richtung der Stirnkante 22, 23 der Zunge 20, 21 verläuft von einer Kehle 25, die eine Kante 26 des Lappens 11 mit einer Kante 27 der Zunge 21 bilden, zu einer entsprechenden schräg gegenüberliegenden Kehle 28. Die beiden Ecken, die von der Stirnkante 22 und einer Kante 29, 29'; 27, 27' gebildet sind, weisen einen großen Radius auf.The direction of the front edge 22, 23 of the tongue 20, 21 runs from a groove 25 which forms an edge 26 of the Form flap 11 with an edge 27 of the tongue 21, too a corresponding diagonally opposite throat 28. The two corners from the front edge 22 and an edge 29, 29 '; 27, 27 'are formed have a large radius.

Ein isolierter Kupferdraht 30 (Leitung) ist zuerst um den Lappen 11 bis in die Kehle 28 gewickelt, danach in die Rille 24 bis zur anderen Kehle 25 eingelegt, und schließlich ist das Endstück 31 des Drahtes 30 am Lappen 11 festgelegt. Anschließend erfolgt das elektrische Widerstandsschweißen (Fig. 1) durch Hubbewegung der Elektrode 16 gemäß Pfeile 17 (F i g. 1); hierbei werden der Draht 30 und die beiden Stirnkanten 22,23 derart zusammengequetscht und erhitzt, daß die Isolierung des Drahtes aufweicht und mittels des erweichten Zinns auf der Oberfläche des Anschlußstücks 10 eine elektrische (metallische), unlösbare Verbindung zwischen dem Anschlußstück 10 und dem Grad 30 zustandekommt.An insulated copper wire 30 (line) is wrapped first around the tab 11 up to the throat 28, then in the groove 24 inserted up to the other throat 25, and finally the end piece 31 of the wire 30 is on Flaps 11 set. The electrical resistance welding (Fig. 1) then takes place by means of a lifting movement the electrode 16 according to arrows 17 (FIG. 1); here the wire 30 and the two end edges 22, 23 squeezed together and heated in such a way that the insulation of the wire softens and by means of the softened tin on the surface of the connector 10 is an electrical (metallic), non-detachable Connection between the connector 10 and the degree 30 comes about.
