Abstract

The spring sets and terminals are intended for the field coil of a compact miniature relay, whose terminals can be secured in its housing. The terminal inner ends are fitted with switching and contact springs, or extensions for securing the lead wires of the field coil, as in 2830074. The terminals (6-9) are stamped from a flat metal strip. The stamping process leads connecting straps between the stamped terminals. Then stationary contacts (23, 23') are welded to the contact springs, while a switching spring (6') is provided with welded switching contacts (24). Then the connecting straps are severed and the ends with the contacts are angularly bent. Then the assembly is inserted as a unit into the relay housing.

Description

Die Erfindung betrifft ein Verfahren zum Herstellen von Federsätzen und Anschlüssen für die Erregerwicklung mit im Gehäuse fixierbaren Anschlüssen, die an den inneren Enden Schalt- und Kontaktfedern bzw. Verlängerungen für die Befestigung der Anschlussdrähte der Erregerwicklung tragen, insbesondere für Minikompaktrelais nach Patent (Patentanmeldung P 28 30 074.5).The invention relates to a method for producing sets of springs and connections for the field winding with connections that can be fixed in the housing and that have switching and contact springs or extensions on the inner ends for attaching the connection wires of the field winding, in particular for mini-compact relays according to patent (patent application P 28 30 074.5).

Nach dem Hauptpatent ist das Relaisgehäuse durch eine Wanne und außen auf Seitenwänden derselben aufgebrachten Plattenteilen gebildet, die zwischen sich und den Seitenwänden die Anschlüsse für die Federsätze und der Erregerwicklung dicht und fest aufnehmen. Bei einem weiter bekannten Relais dieser Art sind die Anschlüsse in Gehäusehalbschalen umspritzt gehalten. Den Relais ist insgesamt der Nachteil gemeinsam, dass die Anschlüsse nur in umständlicher Weise unabhängig in die Gehäuseteile einbringbar sind.According to the main patent, the relay housing is formed by a trough and plate parts which are applied to the outside of the side walls of the same and which tightly and firmly accommodate the connections for the sets of springs and the field winding between them and the side walls. In a further known relay of this type, the connections are held in overmolded housing shells. The overall disadvantage of the relays is that the connections can only be brought into the housing parts independently in a cumbersome manner.

Die Erfindung hat eine weitere Ausbildung des Gegenstandes des Hauptpatentes, dadurch zum Inhalt, dass die Anschlüsse gemeinsam gleichzeitig unter Belassung von Verbindungsstegen aus einem ebenen Metallstreifen ausgeschnitten, nachfolgend mit Festkontakten und einer Schaltfeder mit Schaltkontakten verschweißt, sodann von weiteren Verbindungsstegen befreit und an den die Festkontakte und der Schaltfeder zugewandten Enden abgewinkelt sowie weitere Verbindungsstege weggeschnitten werden und danach als einstückiger Schnittformteil in das Gehäuse des Relais eingesetzt und durch Freischneiden von den restlichen Verbindungsstegen unabhängig werden. Die Verfahrensschritte erlauben eine gleichzeitige Herstellung der Anschlüsse mit Federsätzen und Verlängerungen und geben die Voraussetzung zur Automatisierung der Herstellung und der Montage derselben.The invention has a further development of the subject matter of the main patent, in that the connections are cut out of a flat metal strip at the same time while leaving connecting webs, then welded to fixed contacts and a switching spring with switching contacts, then freed from further connecting webs and to which the fixed contacts and the ends facing the switching spring are angled and further connecting webs are cut away and then inserted as a one-piece sectional molded part into the housing of the relay and are made independent of the remaining connecting webs by cutting them free. The process steps allow the connections to be made simultaneously with sets of springs and extensions and provide the prerequisites for automating the production and assembly of the same.

Es versteht sich, dass das Verfahren gleichermaßen bei Relais mit beliebig großen Bauformen anwendbar ist.It goes without saying that the method can be used equally with relays with any size.

Die Erfindung ist in der Zeichnung an einem Ausführungsbeispiel verdeutlicht.The invention is illustrated in the drawing using an exemplary embodiment.

Mit 21´ ist ein Metallstreifen, z.B. ein dünner Federblechstreifen bezeichnet, der von einer Vorratsrolle (nicht gezeigt) abgewickelt sein kann oder als Rähmchen ausgebildet ist. Mittels eines Schnittwerkzeuges mit Stempel 23 bis 38 werden zunächst die Anschlüsse 6, 7, 8, 9 und die Verbindungsstege 1´, 2´, 3´, 4´; 1´´, 2´´, 3´´, 4´´, 5´´ und 1´´´, 2´´´, 3´´´, 4´´´ ausgeschnitten. Nach Verschweißen einer Schaltfeder 6´ auf den Anschluss 6 und der Festkontakte 23, 23´ auf die Anschlüsse 7 und 8 werden die Anschlüsse 6, 7, 8, 9 von den Verbindungsstegen 1´, 2´, 3´, 4´ befreit und die Anschlüsse 6, 7, 8 um die Biegelinien 39, 40, 41 abgewinkelt sowie die Verbindungsstege 1´´, 2´´, 3´´, 4´´, 5´´ weggeschnitten. Der verbleibende Schnittformteil wird danach in das Gehäuse (nicht gezeigt) des Relais eingesetzt und danach die Anschlüsse 6, 7, 8, 9 von den Verbindungsstegen 1´´´, 2´´´, 3´´´, 4´´´ freigeschnitten.A metal strip, e.g. a thin spring sheet metal strip, is designated by 21 ', which can be unwound from a supply roll (not shown) or is designed as a frame. By means of a cutting tool with punch 23 to 38, the connections 6, 7, 8, 9 and the connecting webs 1 ', 2', 3 ', 4'; 1 ", 2", 3 ", 4", 5 "and 1" ", 2" ", 3" ", 4" "cut out. After welding a switching spring 6 'to the connection 6 and the fixed contacts 23, 23' to the connections 7 and 8, the connections 6, 7, 8, 9 are freed from the connecting webs 1 ', 2', 3 ', 4' and the Connections 6, 7, 8 angled around the bending lines 39, 40, 41 and the connecting webs 1 ″, 2 ″, 3 ″, 4 ″, 5 ″ cut away. The remaining cut part is then inserted into the housing (not shown) of the relay and then the connections 6, 7, 8, 9 are cut free from the connecting webs 1 ″ ″, 2 ″ ″, 3 ″ ″, 4 ″ ″.
