Abstract

A socket terminal strip is provided for receiving a complementary plug strip provided with knife contact pins. The socket terminal strip has an insulating body in whose chambers contact members are arranged. A row of webs extending crosswise is positioned longitudinally on the back side, which webs are separated from each other by incisions, so that a chamber-like arrangement is formed. In order to provide for increased connection possibilities with different contact assignment for the same number of contacts, a row of webs and incisions is provided on each of the two longitudinal edges on the back side of the insulating body, which webs and incisions are staggered. An incision of the second row is thus opposite to a corresponding web of the first row, and a web of the second row is opposite to a corresponding incision of the first row. Each chamber has two contact members with connection parts which reach out of the insulating body on opposing sides, such that the connection part are led alternatively over the webs and lie in the incisions. By this means electrically common connection lugs can then be soldered into different printed-circuit boards, thereby increasing the number of different connections that can be made to the plug strip.

Description

Die Erfindung geht von einer Buchsenleiste nach dem Oberbegriff des Anspruches 1 aus.The invention is based on a female header according to the preamble of claim 1.

Derartige Buchsenleisten sind als sogenannte Peritelevisionsverbindungen bekannt.Such socket strips are known as so-called Peritelevisionsverbindungen.

Bedingt durch neue Dienste in der Rundfunk-und Fernsehkommunikation, insbesondere im privaten Bereich, gewinnt die Peritelevision an zunehmender Bedeutung. Man denke hierbei nur an neue Anwendungen der Videotechnik, wie z. B. Videorecorder, elektronische Spiele, Videokameras, Videographie, Bildschirmtext, Videotext und vieles andere mehr. Auch die Einführung von Datenverarbeitungsgeräten im Heimbereich zählt hierzu. Der private Fernsehempfänger dient in diesen Anwendungsfällen als Sichtgerät. Diese neuen Dienste bzw. die entsprechenden audiovisuellen Geräte sollen allein oder auch gleichzeitig betrieben werden können. Ausserdem sollen sie für den Laien leicht bedienbar sein. Es bestand deshalb die Notwendigkeit, für die verschiedenen Geräte des audiovisuellen Systems eine universelle Verbindung zu schaffen. Diese Verbindung besteht aus einem Buchsenteil, der am Gerät fest montiert ist, und einem Steckerteil, der sich am Ende eines flexiblen Kabels befindet. Beide Teile weisen zwei Reihen von je 10 Kontakten in gegeneinander versetzter Anordnung auf und einen zusätzlichen Kontakt für die Abschirmung. Diese Abschirmung umgibt den Isolierteil, der die einzelnen Kontakte trägt. Als Kontakte werden Gabelfedern verwendet. Die Belegung der einzelnen Kontakte ist in einer Norm festgelegt. Abhängig von der beabsichtigten Anwendung gibt es vier Kabeltypen, wovon ein Typ alle in der genannten Norm aufgeführten Verbindungen enthält. Ein weiterer Typ enthält alle Video-Verbindungen ausser Audio. Der dritte Typ enthält die Anschlüsse für Audio-und Videosignale jedoch ohne RGB beim Farbfernseher. Der letzte Typ umfasst schliesslich alle Audio-Verbindungen ausser Video.Due to new services in radio and television communication, especially in the private sector, the peritelevision is becoming increasingly important. Just think of new applications in video technology, such as B. VCR, electronic games, video cameras, videography, on-screen text, teletext and much more. This also includes the introduction of data processing devices in the home area. In these applications, the private television receiver serves as a viewing device. These new services and the corresponding audiovisual devices should be able to be operated alone or simultaneously. In addition, they should be easy to use for the layperson. There was therefore a need to create a universal connection for the various devices of the audiovisual system. This connection consists of a socket part, which is permanently attached to the device, and a plug part, which is located at the end of a flexible cable. Both parts have two rows of 10 contacts each in a staggered arrangement and an additional contact for shielding. This shield surrounds the insulating part that carries the individual contacts. Fork springs are used as contacts. The assignment of the individual contacts is specified in a standard. Depending on the intended application, there are four types of cables, one of which contains all the connections listed in the standard. Another type contains all video connections except audio. The third type contains the connections for audio and video signals but without RGB for color television. The last type includes all audio connections except video.

Aus der DE-OS 24 52 402 ist bereits eine Gabelfeder bekannt, die in einer Kammer einer Buchsenleiste eingesetzt ist. Sie besitzt als ebenes Stanzteil zwei Anschlussteife zu beiden Seiten. In der Mitte ist eine U-förmige Kontaktgabel vorhanden, die über einen Mittelsteg mit einem Streifenteil verbunden ist. An dem Streifenteil schliessen sich beidseitig zwei U-förmige Anschlussfahnen an, deren Enden unten aus dem Gehäuse der Buchsenleiste herausragen. Mit diesen beiden Anschlussfahnen ist die Gabelfeder zusammen mit dem Gehäuse in nur eine gedruckte Schaltungsplatte eingelötet.From DE-OS 24 52 402 a fork spring is already known, which is used in a chamber of a socket strip. As a flat stamped part, it has two connecting bars on both sides. In the middle there is a U-shaped contact fork, which is connected to a strip part via a central web. The strip part is adjoined on both sides by two U-shaped connection lugs, the ends of which protrude from the bottom of the housing of the socket strip. With these two connection lugs, the fork spring is soldered together with the housing into just one printed circuit board.

Eine Rand-Steckverbindung für gedruckte Schaltungen ist aus der DE-OS 28 51 712 bekannt. Zur Kontaktierung der Leiterbahnen dient eine U-förmige Kontaktgabel, die über einen Steg mit zwei Steckanschlüssen für Anschlussdrähte verbunden ist. Die Anschlussdrähte sind am Ende abisoliert. Gehalten werden die Anschlussdrähte in den Steckanschlüssen durch als federnde Arme ausgebildete Widerhaken, die in Einsteckrichtung des Anschlussdrahtes zur Mitte geneigt angordnet sind.An edge connector for printed circuits is known from DE-OS 28 51 712. A U-shaped contact fork is used to make contact with the conductor tracks and is connected to two plug connections for connecting wires via a web. The connection wires are stripped at the end. The connecting wires are held in the plug connections by barbs designed as resilient arms, which are arranged inclined towards the center in the direction of insertion of the connecting wire.

In der DE- PS 2 104406 ist ebenfalls eine Steckverbindung zur Verbindung zweier Leiterplatten mit einer U-förmigen Gabelfeder beschrieben. Ein Gehäuse besitzt mehrere Kammern, in die jeweils die Gabelfedern eingesetzt sind. Diese Gabelfedern sind aus einem einzigen Stanzteil hergestellt, das an einer Biegekante so gebogen ist, dass zwei im wesentlichen symmetrische Kontaktfederteile entstehen. Ausserdem ist ein Lappen vorgesehen, der dazu dient, beideTeile nach dem Zusammenlegen zusammenzuhalten. Dadurch, dass es sich um eine Steckverbindung zwischen zwei in gleicher Ebene liegenden Leiterplatten handelt, ist kein Anschlussteil erforderlich.In DE-PS 2 104406 a connector for connecting two circuit boards with a U-shaped fork spring is also described. A housing has several chambers, in each of which the fork springs are inserted. These fork springs are made from a single stamped part that is bent at one bending edge so that two essentially symmetrical contact spring parts are created. In addition, a rag is provided which serves to hold both parts together after being folded. Because there is a plug connection between two circuit boards lying on the same level, no connecting part is required.

Aufgabe der vorliegenden Erfindung ist es, eine Buchsenleiste nach der eingangs genannten Art zu schaffen, die bei gleicher Anzahl der Kontakte mehrere Anschlussmöglichkeiten mit unterschiedlicher Belegung der Kontakte in mehreren Ebenen gestattet.The object of the present invention is to provide a socket strip of the type mentioned at the outset, which, with the same number of contacts, allows several connection options with different assignment of the contacts in several levels.

Diese Aufgabe wird erfindungsgemäss durch die im Kennzeichnungsteil des Anspruches 1 angegebenen Merkmale gelöst.According to the invention, this object is achieved by the features specified in the characterizing part of claim 1.

Vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen.Advantageous refinements result from the subclaims.

Die Erfindung wird nachfolgend für zwei Ausführungsbeispiele anhand der Zeichnungen näher erläutert.The invention is explained in more detail below for two exemplary embodiments with reference to the drawings.

Figur 1 zeigt in perspektivischer Ansicht eine Buchsenleiste, die aus einem länglichen, aus Kunststoff hergestellten Isolierstoffkörper 1 besteht. An den beiden Schmalseiten ist je ein Ansatz 19 angeformt, in dem ein Durchbruch 20 ausgespart ist. An jedem Ansatz angeformt ist auf der Unterseite eine Haltezunge 18, mit der der Isolierstoffkörper in eine in den Figuren nicht dargestellte gedruckte Schaltung eingeschnappt und gehalten werden kann. Mit Hilfe von durch die Durchbrüche gesteckten Schrauben ist der Isolierstoffkörper zusammen mit der gedruckten Schaltung an einem Gehäusechassis befestigt. An der Vorder- seiteistderlsolierstoffkörper1 1 mit einer umlaufenden Vertiefung 21 zur Aufnahme der metallenen Abschirmung des Steckers versehen. Durch die Vertiefung 21 wird im lsolierstoffkörper 1 ein umlaufender Rand 22 und ein Mittelteil 23 gebildet. In die Vertiefung 21 ist als Kontaktelemente eine Gabelfeder eingesetzt, die die Abschirmung des Steckers mit Masse verbindet.Figure 1 shows a perspective view of a socket strip, which consists of an elongated, made of plastic insulating body 1. On the two narrow sides, an extension 19 is formed, in which an opening 20 is recessed. Formed on each shoulder is a holding tongue 18 on the underside, with which the insulating body can be snapped and held in a printed circuit, not shown in the figures. With the help of screws inserted through the openings, the insulating body is fastened to a housing chassis together with the printed circuit. On the front side, the insulating body 11 is provided with a circumferential recess 21 for receiving the metal shielding of the plug. A circumferential edge 22 and a central part 23 are formed in the insulating body 1 by the recess 21. In the recess 21, a fork spring is used as contact elements, which connects the shield of the plug to ground.

Im Mittelteil 23 sind zwei parallele sich in Längsrichtung des Isolierstoffkörpers erstreckende, gegeneinander versetzte Reihen von Kammern 2 vorgesehen. In die Kammern sind Kontaktelemente 3 in der Form von U-förmigen Gabelfedern eingesetzt. Wenn eine Steckerleiste in die Buchsenleiste eingeführt wird, dann treten die 3,6 mm breiten Messerstifte der Steckerleiste mit den Gabelfedern in elektrischen Kontakt. In der einen Reihe sind zehn Kammern angeordnet, während sich in der anderen reihe ebenfalls zehn Kammern und der zusätzliche Massekontakt befinden.In the middle part 23 two parallel rows of chambers 2 extending in the longitudinal direction of the insulating material body are provided. Contact elements 3 in the form of U-shaped fork springs are inserted into the chambers. When a plug connector is inserted into the socket connector, the 3.6 mm wide male pins of the connector connector come into electrical contact with the fork springs. Ten chambers are arranged in one row, while in the other row there are also ten chambers and the additional ground contact.

Die Rückseite des lsolierstoffkörpers 1 ist in Figur 2 in perspektivischer Ansicht dargestellt. Entlang des oberen Längsrandes des Isolierstoffkörpers erstreckt sich in einer ersten Reihe abwechselnd in einer kammartigen Anordnung Stege 7 und Einschnitte 8. Entlang des unteren Längsrandes befinden sich in einer zweiten Reihe ebenfalls in einer kammartigen Anordnung Stege 9 und Einschnitte 10. Beide Reihen sind gegeneinanderversetzt, so dass einem Steg 7 der ersten Reihe ein Einschnitt 10 der zweiten Reihe, bzw. einem Einschnitt 8 der ersten Reihe ein Steg 9 der zweiten Reihe gegenüberliegt. Die Stege sind bezüglich der Längsränder quer hierzu angeordnet und sie erstrecken sich, wie aus Figur 2 entnommen werden kann, bis etwa ein Drittel der Breite des Isolierstoffkörpers 1 und zwar bis dahin, wo sich die Austrittsöffnungen der Kontaktelemente aus dem Isolierstoffkörper befinden.The rear of the insulating body 1 is shown in FIG. 2 in a perspective view. Along the upper longitudinal edge of the insulating body, webs 7 and incisions 8 alternate in a first row in a comb-like arrangement. Along the lower longitudinal edge there are webs 9 and incisions 10 in a second row, likewise in a comb-like arrangement. Both rows are offset from one another, so that a web 7 of the first row is opposite an incision 10 of the second row, or an incision 8 of the first row is a web 9 of the second row. The webs are arranged transversely with respect to the longitudinal edges and, as can be seen from FIG. 2, they extend to about a third of the width of the insulating material body 1, to the point where the outlet openings of the contact elements from the insulating material body are located.

Figur 3 zeigt in perspektivischer Ansicht ein Paar in einer Kammer angeordneter Kontaktelemente 3 ohne Isolierstoffkörper. Es handelt sich hierbei um sogenannte Gabelfedern. Sie bestehen aus einem U-förmigen Kontaktteil 4, an das sich zwei Anschlussteile 5, 24 und eine Anschlussfahne 6 anschliesst. Das Kontaktelement 3 ist zwischen dem Kontaktteil und dem ersten Anschlussteil 5 mit einer Einschnürung versehen, so dass sich eine erste Sollbiegestelle 11 ergibt. Zwischen dem ersten Anschlussteil 5 und dem zweiten Anschiusstei) 24 befindet sich eine weitere Einschnürung, so dass hierdurch eine zweite Sollbiegestelle 12 gebildet wird. Schliesslich ist die Anschlussfahne 6 und der zweite Anschlussteil 24 durch eine weitere Einschnürung miteinander verbunden. Dies stellt die Befestigungsstelle 13 dar. Das Kontaktelement kann nun je nach Bedarf an den Sollbiegestellen oder auch an der Befestigungsstelle in etwa einem rechten Winkel abgebogen werden.FIG. 3 shows a perspective view of a pair of contact elements 3 arranged in a chamber without an insulating body. These are so-called fork springs. They consist of a U-shaped contact part 4, to which two connecting parts 5, 24 and a connecting lug 6 are connected. The contact element 3 is provided with a constriction between the contact part and the first connection part 5, so that there is a first predetermined bending point 11. There is a further constriction between the first connecting part 5 and the second connecting member 24, so that a second predetermined bending point 12 is thereby formed. Finally, the connecting lug 6 and the second connecting part 24 are connected to one another by a further constriction. This represents the fastening point 13. The contact element can now be bent at approximately a right angle as required at the predetermined bending points or also at the fastening point.

Um nun die Möglichkeiten der äusseren Beschaltung zu erhöhen, ist erfindungsgemäss in jeder Kammer ein zweites Kontaktelement angeordnet, das zumindest bezüglich des Kontaktteils 4 mit dem ersten Kontaktelement deckungsgleich ist. Die Anschlussfahnen können jedoch verschieden sein, z.B. geeignet für gedruckte Schaltungen, für Drahtanschlüsse usw. Die beiden Kontaktelemente einer Kammer sind an unterschiedlichen Sollbiegestellen umgebogen. So ist ein Kontaktelement an der zweiten Sollbiegestelle gebogen und über den Steg z.B. der ersten Reihe geführt, während das andere Kontaktelement an der ersten Sollbiegestelle gebogen ist und in dem dem Steg gegenüberliegenden Einschnitt der anderen Reihe liegt. Beide Anschlussfahnen liegen damit in unterschiedlichen Ebenen und sie ragen auf unterschiedlichen Seiten aus dem Isolierstoffkörper heraus. Bei den beiden Nachbarkontaktelementen ist es genau umgekehrt.In order to increase the possibilities of the external wiring, a second contact element is arranged in each chamber according to the invention, which is congruent with the first contact element at least with respect to the contact part 4. However, the connection lugs can be different, e.g. suitable for printed circuits, for wire connections etc. The two contact elements of a chamber are bent at different predetermined bending points. A contact element is bent at the second predetermined bending point and e.g. the first row, while the other contact element is bent at the first predetermined bending point and lies in the incision of the other row opposite the web. Both connection lugs are on different levels and they protrude from the insulating body on different sides. With the two adjacent contact elements, it is exactly the opposite.

Ist nun eine erste Reihe von Stegen und Einschnitten vorhanden, so ist z.B. ein Kontaktelement aus der zweiten Kammerreihe an der ersten Sollbiegestelle umgebogen. Das benachbarte Kontaktelement aus der ersten Kammerreihe ist entlang der Kontur des Steges geführt und an der zweiten Sollbiegestelle umgebogen. Die Kontaktfahnen beider Kontaktelemente liegen in verschiedenen Ebenen, wobei das Kontaktelement der ersten Kammerreihe in dem Einschnitt liegt, während die Anschlussfahne des Kontaktelementes der zweiten Kammerreihe auf der Höhe der Oberkante des Steges aus dem Isolierstoffkörper herausragt.If there is now a first row of bars and incisions, e.g. bent a contact element from the second row of chambers at the first predetermined bending point. The adjacent contact element from the first row of chambers is guided along the contour of the web and bent at the second predetermined bending point. The contact lugs of both contact elements lie in different planes, the contact element of the first row of chambers lying in the incision, while the connecting lug of the contact element of the second row of chambers protrudes from the insulating material body at the level of the upper edge of the web.

Um die einzelnen Anschlussteile besser und elektrisch sicherer voneinander zu trennen, sind zwischen den einzelnen Anschlussteilen dünne Rippen 15 an den Isolierstoffkörper 1 angeformt. Diese erstrecken sich zwischen den Stegen und Einschnitten der beiden Reihen. In Figur 5 ist dies dargestellt.In order to separate the individual connecting parts better and more electrically, thin ribs 15 are formed on the insulating body 1 between the individual connecting parts. These extend between the webs and incisions of the two rows. This is shown in FIG. 5.

Zur Befestigung der Kontaktelemente an dem Isolierstoffkörper sind an den Stegen und in den Einschnitten längsrandseitig Zungen 14 vorgesehen, die verformbar sind und mit deren Hilfe die Kontaktelemente an den Befestigungsstellen 13 festgelegt werden. Die Festlegung erfolgt durch Warmverformung der Zungen z.B. mittels eines Stempels.To fasten the contact elements to the insulating body, tongues 14 are provided on the webs and in the incisions on the longitudinal edge side, which are deformable and with the aid of which the contact elements are fixed at the fastening points 13. The determination is made by hot deformation of the tongues e.g. by means of a stamp.

Wie aus Figur 2 zu entnehmen ist, ist an jeden Steg ein Stützzapfen 17 angeformt, auf dem sich der Anschlussteil abstützt. Die Stützzapfen befinden sich an dem den Zungen 14 gegenüberliegenden Ende der Stege.As can be seen from Figure 2, a support pin 17 is formed on each web, on which the connecting part is supported. The support pins are located at the end of the webs opposite the tongues 14.

Bei einem ersten Ausführungsbeispiel liegen die beiden Kontaktelemente in den Kammern so, dass sich beide Kontaktteile berühren. Eine weitere zweite Ausführung sieht gemäss Figur 4 vor, dass die Kontaktteile durch Querwände 16 voneinander getrennt sind. Wird der relativ breite Steckerstift eingeführt, so werden beide Kontaktelemente elektrisch miteinander verdunden. Der Steckerstift hat damit die Funktion einer Kontaktbrücke übernommen.In a first embodiment, the two contact elements are located in the chambers in such a way that both contact parts touch. According to FIG. 4, another second embodiment provides that the contact parts are separated from one another by transverse walls 16. If the relatively wide connector pin is inserted, both contact elements are electrically twisted together. The plug pin has thus taken over the function of a contact bridge.
