Abstract

Device for plugging onto a group of pins of a terminal panel. It is desired to combine the pins of a terminal panel such that a specific selectable group of these pins provides connection conditions to a contact spring strip, which conditions are comparable to a blade strip. Small metal plates having a perforation like a locking hole are anchored in a dielectric plate. The perforations have two partial openings separated from one another by a narrow point. The plate is plugged onto the pins with the larger of the respective partial openings and is pushed laterally at a chosen plug depth, the edge of the smaller, second partial opening engaging in the pins and fixing the plate in the plug direction. The plate, provided with guide walls, together with the free pin ends now forms a blade strip with which one or more contact blade strips arranged side-by-side can be plugged together for a specific purpose. The device simplifies the making of contacts with pins of a terminal panel, e.g. of rear wall wiring with spring strips. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Vorrichtung zum Aufstecken auf Stifte oder Pfosten, die in einem bestimmten Raster mit zueinander parallelem Verlauf angeordnet sind, mit einer Iso­lierstoffplatte, die im Raster der Stifte oder Pfosten von Kanälen durchsetzt ist.The invention relates to a device for attaching to pins or posts, which are arranged in a certain grid with a parallel course, with an insulating plate which is penetrated by channels in the grid of pins or posts.

Eine solche Vorrichtung ist z.B. aus der DE-PS 30 21 049 be­kannt. Die auf die Pfosten eines Anschlußfeldes aufsteckbare Isolierstoffplatte ist dabei Bestandteil einer Steckvorrich­tung, die Kontaktfedern enthält, welche jeweils mit einem der Pfosten beim Aufstecken der Vorrichtung in Verbindung treten. Kontaktelementfreie Blindkammern, die im Rechteck­raster der Pfosten liegen, verhindern mit einem rechtwinklig zur Einführungsrichtung eines Pfostens, also Kontaktstiftes des Anschlußfeldes, daß beim Aufstecken der Vorrichtung eine bestimmte Stecktiefe überschritten wird. Dadurch kann die An­schlußvorrichtung beim Aufstecken auf die Stifte eines Wrap­stiftfeldes mit den Stiften durch Wrapen hergestellte Leitungs­verbindungen nahe einer Isolierstoffplatte nicht beeinträch­tigen, in der die Wrapstifte verankert sind. Allerdings bietet die bekannte Vorrichtung keine Möglichkeit, die Stecktiefe wahlweise einzustellen.Such a device is e.g. known from DE-PS 30 21 049. The insulating material plate which can be plugged onto the posts of a connection field is part of a plug-in device which contains contact springs which each come into contact with one of the posts when the device is plugged on. Contact element-free blind chambers, which lie in the rectangular grid of the posts, prevent with a right angle to the insertion direction of a post, that is, the contact pin of the connection field, that a certain insertion depth is exceeded when the device is plugged on. As a result, the connecting device cannot interfere with line connections made by wrap when plugged onto the pins of a wrap pin array with the pins, in which the wrap pins are anchored. However, the known device does not offer the option of optionally setting the insertion depth.

Es ist daher Aufgabe vorliegender Erfindung, eine Vorrich­tung der eingangs genannten Art so auszugestalten, daß die Stecktiefe der Vorrichtung in gewissem Umfang frei gewählt werden kann.It is therefore an object of the present invention to design a device of the type mentioned at the outset in such a way that the insertion depth of the device can be freely selected to a certain extent.

Erfindungsgemäß ergibt sich die Lösung dieser Aufgabe dadurch, daß wenigstens einigen der Kanäle quer zur Verlaufsrichtung der Kanäle angeordnete und mit einem ringförmig geschlosse­nen Außenrand im Isolierstoffkörper der Platte verankerte Metallplättchen zugeordnet sind, daß die Metallplättchen jeweils mit einem schlüssellochartigen Durchbruch versehen sind, der zwei durch eine Engstelle voneinander getrennte, verschieden große Teilöffnungen aufweist, und daß die Kanäle jeweils einen beide Teilöffnungen umfassenden Querschnitt haben.According to the invention, this object is achieved in that at least some of the channels arranged transversely to the direction of the channels and anchored with an annularly closed outer edge are anchored in the insulating body of the plate, that the metal plates are each provided with a keyhole-like opening, two by one Has narrow openings that are separate from one another and of different sizes, and that the channels each have a cross section that includes both partial openings.

Bei geeigneter Bemessung der beiden Teilöffnungen läßt sich die Platte mit Hilfe der größeren Teilöffnungen ungehindert auf die Stifte oder Pfosten des Anschlußfeldes aufschieben. Beim Erreichen einer vorwählbaren bestimmten Stecktiefe wird die Platte quer zum Verlauf der Stifte so verschoben, daß die Stifte von der größeren Teilöffnung über die Engstelle in die kleinere Teilöffnung gedrückt werden. Ist die kleinere Teil­öffnung dabei so auf das Profil der Stifte abgestimmt, daß sich die Berandung der kleineren Teilöffnung teilweise in die Stifte eingräbt, so wird die Vorrichtung dadurch an den Stiften ver­ankert. Die Stecktiefe einer auf die Stifte aufgesteckten Kon­taktfederleiste wird nun durch die Platte so begrenzt, daß z.B. Wrapverbindungen, die unterhalb der Platte liegen, vor Beein­trächtigungen geschützt sind.With a suitable dimensioning of the two partial openings, the plate can be pushed freely onto the pins or posts of the connection panel using the larger partial openings. When a preselectable specific insertion depth is reached, the plate is displaced transversely to the course of the pins in such a way that the pins are pressed from the larger partial opening via the narrow point into the smaller partial opening. If the smaller partial opening is matched to the profile of the pins in such a way that the edge of the smaller partial opening partially digs into the pins, the device is thereby anchored to the pins. The insertion depth of a contact female connector plugged onto the pins is now limited by the plate so that e.g. Wrap connections that lie below the plate are protected from impairments.

In weiterer Ausgestaltung der Erfindung kann vorgesehen sein, daß die kleinere der beiden Teilöffnungen zwei von einem rechtwinklig zur Verbindungslinie der beiden Teilöffnungen gerichteten Querrand ausgehende Schrägränder aufweist, die keilförmig in Richtung zur Engstelle aufeinanderzulaufen und in die abgerundete Engstelle übergehen, und daß die größere Teilöffnung ein rechteckiges Profil mit abgerundetem Übergang zur Engstelle hat.In a further embodiment of the invention, it can be provided that the smaller of the two partial openings has two oblique edges starting from a transverse edge directed at right angles to the connecting line of the two partial openings, which converge in a wedge shape towards the narrow point and merge into the rounded narrow point, and that the larger partial opening opens has a rectangular profile with a rounded transition to the constriction.

Durch diese Ausgestaltung der Teilöffnungen wird sicher ver­hindert, daß die von der Berandung der kleineren Teilöffnung umschlossenen Pfosten nicht wieder aus diesen Teilöffnungen in unerwünschter Weise herauswandern können.This configuration of the partial openings reliably prevents the posts enclosed by the edges of the smaller partial opening from being able to migrate out of these partial openings again in an undesirable manner.

Ferner kann im Rahmen vorliegender Erfindung vorgesehen sein, daß die rechteckförmige Platte entlang ihrer Längsseiten mit parallel zum Verlauf der Kanäle gerichteten, einseitig von der Platte abstehenden Wänden versehen ist, daß die Wände an ihren Seiten die der Platte zugewandt sind, Füh­rungsrippen aufweisen, daß die Wände in die Querseiten der Platte übergreifende Abwinkelungen aufweisen und daß die Platte auf der von den Wänden abgewandten Seite mit Einführungsab­schrägungen versehen ist, die die einzelnen Kanäle lediglich in dem Teilbereich umgeben, der der größeren Teilöffnung zuge­ordnet ist.Furthermore, it can be provided in the context of the present invention that the rectangular plate is provided along its longitudinal sides with walls directed parallel to the course of the channels and projecting on one side from the plate, that the walls on their sides facing the plate have guide ribs that Have walls in the transverse sides of the plate cross-bends and that the plate is provided on the side facing away from the walls with chamfers that surround the individual channels only in the portion that is assigned to the larger partial opening.

Wände und Rippen erleichtern zusätzlich die Zuordnung von Kontaktfederleisten zu Pfosten-Gruppen des Anschlußfeldes, mit denen die Kontaktfedern der Kontaktfederleisten in Ver­bindung treten sollen und die nur den größeren Teilöffnungen zugeordneten Einführungsabschrägungen begünstigen beim Auf­stecken der Platte auf die Stifte oder Pfosten des Anschluß­feldes, daß die Stifte den größeren Teilöffnungen zugeführt werden.Walls and ribs additionally facilitate the assignment of contact spring strips to post groups of the connection field with which the contact springs of the contact spring strips are to come into contact and the insertion bevels associated only with the larger partial openings, when the plate is plugged onto the pins or posts of the connection field, favor that the pins are fed to the larger partial openings.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand von drei Figuren noch näher erläutert.An embodiment of the invention is explained in more detail below with reference to three figures.

Dabei zeigen, jeweils stark vergrößert,

  • FIG 1 ein Verriegelungsplättchen, wie es bei der Vorrich­tung verwendet wird, von oben gesehen,
  • FIG 2 in Seitenansicht und im Schnitt ein Abschnitt der Vorrichtung und
  • FIG 3 die Vorrichtung von oben gesehen.
Show, greatly enlarged,
  • 1 shows a locking plate as used in the device, seen from above,
  • 2 in side view and in section a section of the device and
  • 3 seen the device from above.

Im einzelnen ist den Figuren zu entnehmen, daß eine nicht­leitende Isolierstoffplatte 1 von zueinander parallelen Ka­nälen 2 durchsetzt ist, die in einem bestimmten Rastermaß angeordnet sind.In detail, it can be seen from the figures that a non-conductive insulating material plate 1 is penetrated by channels 2 which are parallel to one another and which are arranged in a certain grid dimension.

Jedem Kanal ist ein Verriegelungsplättchen 3 zugeordnet. Die Verriegelungsplättchen 3 sind mit ihren Flachseiten quer zur Verlaufsrichtung der Kanäle 2 so in das Kunst­stoffmaterial der Platte 1 eingebettet, daß sie fest in der Platte 1 verankert sind. Die Verriegelungsplättchen 3 sitzen dabei mit einem Außenrand 4 im Material der Plat­te 1.A locking plate 3 is assigned to each channel. The locking plates 3 are embedded with their flat sides transversely to the direction of the channels 2 in the plastic material of the plate 1 that they are firmly anchored in the plate 1. The locking plates 3 sit with an outer edge 4 in the material of the plate 1.

Wie insbesondere FIG 1 zeigt, ist jedes Plättchen 3 mit einem Durchbruch 5 versehen, der ein schlüssellochartiges Profil hat und sich aus zwei Teilöffnungen 6, 7 zusammensetzt, die durch eine Engstelle 8 verbunden sind. Die beiden Teilöff­nungen 6, 7 sind ungleich groß. Die größere Teilöffnung 7 mit etwa quadratischem Profil ist so bemessen, daß ein Stift, bzw. Anschlußpfosten 9, dessen Umriß in FIG 1 im Bereich der Teilöffnung 7 strichliert angedeutet ist, mit Spiel durch die Teilöffnung 7 des Verriegelungsplättchens 3 hindurchgesteckt werden kann.As shown in FIG 1 in particular, each plate 3 is provided with an opening 5, which has a keyhole-like profile and is composed of two partial openings 6, 7, which are connected by a constriction 8. The two partial openings 6, 7 are not the same size. The larger partial opening 7 with an approximately square profile is dimensioned such that a pin or connecting post 9, the outline of which is indicated by dashed lines in FIG. 1 in the area of the partial opening 7, can be inserted through the partial opening 7 of the locking plate 3 with play.

Die Engstelle 8 ist so bemessen, daß die Dicke des Pfostens 9, also der Abstand von zwei einander gegenüberliegenden Seiten des Pfostens 9, der vorzugsweise ein quadratisches Profil hat, größer ist, als der Abstand der die Engstelle 8 begrenzenden einander gegenüberstehenden Ränder 10 des Verriegelungsplätt­chens. Daher gelangt der Pfosten 9, der die Teilöffnung 7 durch­setzt, nur unter einem bestimmten Kraftaufwand in die Teil­öffnung 6, wenn das Verriegelungsplättchen 3 quer zur Verlaufs­richtung des Pfostens 9 bewegt wird.The constriction 8 is dimensioned such that the thickness of the post 9, i.e. the distance from two opposite sides of the post 9, which preferably has a square profile, is greater than the distance between the opposing edges 10 of the locking plate that delimit the constriction 8 . Therefore, the post 9, which passes through the partial opening 7, only enters the partial opening 6 with a certain amount of force when the locking plate 3 is moved transversely to the direction of the post 9.

Hinter der durch abgerundete Ränder 10 begrenzten Engstelle 8 laufen die Ränder 11 des Plättchens 3, die die Teilöffnung 6 umschließen, schräg auseinander, um schließlich in einen Querrand 12 überzugehen, der die Teilöffnung 6 quer zu einer Verbindungslinie zwischen den Teilöffnungen 6 und 7 begrenzt.Behind the narrow point 8 delimited by rounded edges 10, the edges 11 of the plate 3, which enclose the partial opening 6, run diagonally apart, in order finally to merge into a transverse edge 12 which delimits the partial opening 6 transversely to a connecting line between the partial openings 6 and 7.

Wie aus FIG 1 zu ersehen, ist die Teilöffnung 6 so bemessen, daß die Schrägränder 11 auf einen in der Teilöffnung 6 steckenden Pfosten 9 eine Kraft ausüben, die den Pfosten 9 gegen den Querrand 12 preßt, weil sich auch die beiden Kan­ten 13, die eine der Teilöffnung 7 zugewandte Seite des Pfostens 9 begrenzen, im Bereich der Schrägränder 11, also hinter der Engstelle 8, befinden.As can be seen from FIG. 1, the partial opening 6 is dimensioned such that the oblique edges 11 exert a force on a post 9 inserted in the partial opening 6, which presses the post 9 against the transverse edge 12, because the two edges 13, which delimit a side of the post 9 facing the partial opening 7, in the region of the inclined edges 11, that is to say behind the constriction 8.

Das Profil der Kanäle 2 der Platte 1 ist so bemessen, daß beide Teilöffnungen 6, 7 der Verriegelungsplättchen 3 innerhalb der lichten Weite der Kanäle 2 liegen.The profile of the channels 2 of the plate 1 is dimensioned such that both partial openings 6, 7 of the locking plate 3 lie within the clear width of the channels 2.

Die Platte 1 ist auf der Seite 14, die beim Aufstecken der Platte 1 auf die Pfosten eines Anschlußfeldes den frei­en Enden der Pfosten zugewandt ist, an der Mündung eines jeden Kanals 2 mit Einführungsabschrägungen 15 versehen. Diese Abschrägungen 15 sind jedoch auf den Teilbereich eines jeden Kanals beschränkt, der mit der größeren Teil­öffnung 7 der Verriegelungsplättchen 3 fluchtet. Auf diese Weise wird beim Aufstecken der Platte 1 auf die Pfosten eines Anschlußfeldes das Einführen der Pfosten in die größeren Teilöffnungen 7 begünstigt.The plate 1 is provided on the side 14, which faces the free ends of the posts when the plate 1 is plugged onto the posts of a connection field, at the mouth of each channel 2 with insertion bevels 15. However, these bevels 15 are limited to the partial area of each channel that is aligned with the larger partial opening 7 of the locking plate 3. In this way, the insertion of the posts into the larger partial openings 7 is promoted when the plate 1 is placed on the posts of a connection field.

Auf der von der Seite 14 abgewandten Seite der Platte 1 sind entlang der Längsseiten 16 der Platte 1, die einen etwa recht­eckförmigen Umriß hat, parallel zum Verlauf der Kanäle 2 ge­richtete Führungswände 17 vorgesehen. Die Führungswände greifen mit Abwinkelungen 18 in die Querseiten der Platte über und be­ grenzen dadurch einen Aufnahmeraum, in den eine oder auch mehrere Kontaktfederleisten nebeneinander eingeschoben werden können. Rippen 19 entlang der Längswände sorgen dabei für eine in gewissem Ausmaß elastische Führung der Kontaktfederleisten.On the side of the plate 1 facing away from the side 14, along the longitudinal sides 16 of the plate 1, which has an approximately rectangular outline, guide walls 17 directed parallel to the course of the channels 2 are provided. The guide walls overlap with bevels 18 in the transverse sides of the plate and be thereby delimit a receiving space into which one or more contact spring strips can be inserted next to one another. Ribs 19 along the longitudinal walls ensure a somewhat elastic guidance of the contact spring strips.
