Definitions
- the invention relates to an electrical connector strip which is provided with a plurality of rows of contact elements which are connected by means of connecting elements to a printed circuit board of an electrical assembly, the portions of the connecting elements of the connecting elements of the rows most distant from the printed circuit board projecting from receiving chambers obliquely towards the printed circuit board are turned.
- Connector strips with connecting elements bent vertically outside the receiving chambers are e.g. known from US-A-3 413 594 and GB-A-2 024 539, respectively.
- the invention has for its object to improve the electrical conditions in the connector.
- the deflection within the chamber in particular in the case of the outer connection elements, increases the creepage distances and the distance of the connection element from neighboring assemblies. This improves the electrical conditions of the connector.
- the length of the connecting elements is reduced, which not only saves material, but also improves the electrical conditions.
- the fixing point is given by the widening of the connection element. This widening causes a firm hold in the receiving chamber, so that the connection elements can be bent after the contact elements have been inserted into the receiving chambers. This does not require a cross-section-reducing predetermined bending point. Due to the recess already provided in the injection molded body, the contact elements can be inserted particularly easily into the chambers.
- a multi-row connector strip consists of a housing 1 with chambers 2, into which contact elements 3 are inserted.
- the contact elements 3 are formed in one piece from contact springs 4 and connection elements 5.
- the connecting elements 5 are inserted at their free ends into holes in a printed circuit board 6 which is firmly connected to the housing 1.
- the circuit board extends in the direction of insertion of the connector strip.
- the free ends of the connection elements 5 are consequently outside the housing 1 perpendicular to it.
- the two most distant connection elements 5 from the printed circuit board 6 are angled obliquely towards the printed circuit board 6.
- the beveling already begins within the receiving chambers 2 for the contact elements 3.
- the connecting elements 5 have a collar-like widening 7 at the bending point, which widen into lateral groove-shaped depressions 8 in the inner walls of the receiving chambers 2.
- Fig. 2 shows the shape of the collar-shaped widening 7 of the connecting elements 5 made of flat material, as well as the shape of the groove-shaped recesses 8.
- the bending edge is located directly next to the collar-shaped widening 7. This lies so deep within the receiving chamber 2 that the connecting element 5 on the Outlet opening already has a considerable lateral distance from the side wall of the housing 1. This increases the creepage distances and the other electrical conditions of the connector strip.
- the length of the connecting element 5 is reduced, which enables a smaller punching strip width.

Abstract
Description
Die Erfindung betrifft eine elektrische Steckverbinderleiste die mit mehreren Reihen von Kontaktelementen versehen ist, die mittels Anschlußelementen mit einer Leiterplatte einer elektrischen Baugruppe verbunden sind, wobei die aus Aufnahmekammern für die Kontaktelemente herausragenden Abschnitte der Anschlußelemente der von der Leiterplatte am weitesten entfernten Reihen schräg zur Leiterplatte hin abgebogen sind.The invention relates to an electrical connector strip which is provided with a plurality of rows of contact elements which are connected by means of connecting elements to a printed circuit board of an electrical assembly, the portions of the connecting elements of the connecting elements of the rows most distant from the printed circuit board projecting from receiving chambers obliquely towards the printed circuit board are turned.
Bisher war es üblich, die Anschlußelemente der Steckverderleiste erst außerhalb der Aufnahmekammern für die Kontaktelemente senkrecht oder schräg zur Leiterplatte hin abzubiegen. Steckverbinderleisten mit außerhalb der Aufnahmekammern senkrecht abgebogenen Anschlußelementen sind z.B. aus der US-A-3 413 594 bzw. der GB-A-2 024 539 bekannt.Until now, it was customary to bend the connecting elements of the connector strip only outside the receiving chambers for the contact elements perpendicularly or obliquely to the printed circuit board. Connector strips with connecting elements bent vertically outside the receiving chambers are e.g. known from US-A-3 413 594 and GB-A-2 024 539, respectively.
Der Erfindung liegt die Aufgabe zugrunde, die elektrischen Verhältnisse im Stecker Zu verbessern.The invention has for its object to improve the electrical conditions in the connector.
Diese Aufgabe wird durch die im Patentanspruch beschriebene Steckverbinderleiste gelöst. Durch die Abbiegung innerhalb der Kammer insbesondere bei den äußeren Anschlußelementen werden die Kriechstrecken und der Abstand des Anschlußelementes Zu benachbarten Baugruppen vergrößert. Damit verbessern sich die elektrischen Verhältnisse des Steckers. Außerdem verringert sich die Länge der Anschlußelemente was nicht nur eine Materialersparnis mit sich bringt, sondern ebenfalls die elektrischen Bedingungen verbessert. Die Festlegestelle ist durch die Verbreiterung des Anschlußelementes gegeben. Diese Verbreiterung bewirkt einen festen Halt in der Aufnahmekammer, so daß das Abbiegen der Anschlußelemente nach dem Einsetzen der Kontaktelemente in die Aufnahmekammern erfolgen kann. Es bedarf hierzu keiner querschnittsverringernden Sollbiegestelle. Durch die bereits im Spritzgußkörper vorgesehene Vertiefung können die Kontaktelemente besonders leicht in die Kammern eingeschoben werden.This object is achieved by the connector strip described in the claim. The deflection within the chamber, in particular in the case of the outer connection elements, increases the creepage distances and the distance of the connection element from neighboring assemblies. This improves the electrical conditions of the connector. In addition, the length of the connecting elements is reduced, which not only saves material, but also improves the electrical conditions. The fixing point is given by the widening of the connection element. This widening causes a firm hold in the receiving chamber, so that the connection elements can be bent after the contact elements have been inserted into the receiving chambers. This does not require a cross-section-reducing predetermined bending point. Due to the recess already provided in the injection molded body, the contact elements can be inserted particularly easily into the chambers.
Im folgenden wird die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispieles näher erläutert.

- zeigt einen Querschnitt durch eine Steckverbinderleiste mit einer elektrischen Leiterplatte,
- Fig. 2
- einen Teilschnitt durch die Steckverbinderleiste entlang der Linie II-II in Fig. 1.
- Fig. 1
- shows a cross section through a connector strip with an electrical circuit board,

- a partial section through the connector strip along the line II-II in Fig. 1st
Nach Fig. 1 besteht eine mehrreihige Steckverbinderleiste aus einem Gehäuse 1 mit Kammern 2, in die Kontaktelemente 3 eingesetzt sind. Die Kontaktelemente 3 sind einstückig aus Kontaktfedern 4 und Anschlußelementen 5 gebildet. Die Anschlußelemente 5 sind an ihren freien Enden in Bohrungen einer Leiterplatte 6 eingesetzt, die mit dem Gehäuse 1 fest verbunden ist. Die Leiterplatte erstreckt sich in der Steckrichtung der Steckverbinderleiste. Die freien Enden der Anschlußelemente 5 stehen demzufolge außerhalb des Gehäuses 1 senkrecht dazu. Die beiden von der Leiterplatte 6 am weitesten entfernten Anschlußelemente 5 sind schräg zur Leiterplatte 6 hin abgewinkelt. Die Abschrägung beginnt bereits innerhalb der Aufnahmekammern 2 für die Kontaktelemente 3. Die Anschlußelemente 5 weisen an der Biegestelle eine kragenartige Verbreiterung 7 auf, die in seitliche nutförmige Vertiefungen 8 in den Innenwänden der Aufnahmekammern 2 eingreifen.According to FIG. 1, a multi-row connector strip consists of a housing 1 with
Fig. 2 zeigt die Form der kragenförmigen Verbreiterung 7 der aus Flachmaterial bestehenden Anschlußelemente 5, sowie die Form der nutförmigen Vertiefungen 8. Die Biegekante liegt unmittelbar neben der kragenförmigen Verbreiterung 7. Diese liegt so tief innerhalb der Aufnahmekammer 2, daß das Anschlußelement 5 an der Austrittsöffnung bereits einen erheblichen seitlichen Abstand zur Seitenwand des Gehäuses 1 aufweist. Dadurch vergrößern sich die Kriechstrecken und die sonstigen elektrischen Verhältnisse der Steckverbinderleiste. Außerdem verringert sich die Länge des Anschlußelementes 5, was eine geringere Stanzstreifenbreite ermöglicht.Fig. 2 shows the shape of the collar-shaped widening 7 of the connecting elements 5 made of flat material, as well as the shape of the groove-
