Description

Die Erfindung betrifft einen Steckverbinder für gedruckte oder anderweitig hergestellte Leiterkarten insbesondere gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a connector for printed or otherwise manufactured printed circuit boards, in particular according to the preamble of patent claim 1.

Zur Stromversorgung einer Vielzahl von Leiterkarten in elektronischen Geräten insbesondere für verdrahtete Rückwände in der Computerindustrie sind - unabhängig von der jeweiligen technischen Ausführung der Rückwände beispielsweise in Wickeltechnik, Metallplattentechnik, als gedruckte Schaltung in Löt- oder Einpreßtechnikverschiedene Lösungen für die Stromversorgung und verschiedene Stromschienenkonzepte bekannt, die jedoch prinzipiell eine Gemeinsamkeit aufweisen: Es werden zur Übertragung des Stroms auf die einzelnen Tochterkarten innerhalb der Steckverbindung die üblichen Kontakte des Kartensteckverbinders benutzt. Bekannt ist auch die direkte Kontaktierung einer Stromschiene mittels eines Zusatzsteckers.For the power supply of a large number of printed circuit boards in electronic devices, in particular for wired back panels in the computer industry - regardless of the respective technical design of the back panels, for example in winding technology, metal plate technology, as a printed circuit in soldering or press-fit technology, various solutions for the power supply and various busbar concepts are known However, in principle they have one thing in common: The usual contacts of the card connector are used to transmit the current to the individual daughter cards within the connector. The direct contacting of a busbar by means of an additional plug is also known.

Bei Geräten mit Niederspannungsversorgung, wie sie heute zunehmend insbesondere bei Rechenanlagen vorgesehen ist, erreichen jedoch die über die Stromversorgungskontakte fließenden Ströme erhebliche Werte,so vor allem dann, wenn sehr schnell schaltende Haltbleiterbauelemente mit Metall-Sperrschicht (Schottky-Sperrschicht) verwendet werden. Häufig ist es auch erwünscht, beim Anschließen einer Leiterkarte über den Steckverbinder sicherzustellen, daß die Stromversorgung in jedem Fall für alle Teile der Schaltung sichergestellt ist bevor irgendein Bauelement auf der anzuschließenden Leiterkarte eine bestimmungsgemäße Schaltfunktion ausführen kann. Man spricht hier von einer sogenannten erwünschten "Stromvoreilung". Wird jedoch die Stromversorgung über die üblichen Kontakte des Kartensteckverbinders hergestellt, so müssen bei relativ hohen Versorgungsströmen mehrere Kontakte belegt werden, für die die gleichzeitige und gleichmäßige Kontakgabe gewährleistet sein muß. Ersichtlicherweise stellt in diesem Fall auch die Forderung einer Stromvoreilung ein gewisses Problem dar.In devices with a low-voltage supply, as is increasingly the case today in computing systems, the currents flowing through the power supply contacts reach considerable values, especially when very fast switching semiconductor components with a metal barrier layer (Schottky barrier layer) are used. It is also often desirable when connecting a circuit card via the connector to ensure that the power supply is guaranteed for all parts of the circuit before any component on the circuit card to be connected can perform an intended switching function. One speaks here from a so-called desired "current advance". However, if the power supply is established via the usual contacts of the card connector, then at relatively high supply currents, several contacts must be occupied, for which the simultaneous and uniform contact must be guaranteed. Obviously, in this case, the requirement for a power lead is also a certain problem.

Die andere bekannte Lösung der direkten Kontaktierung der Stromschiene mittels eines Zusatzsteckers ist jedoch offensichtlich aufwendiger und kann in manchen Fällen auch zu räumlichen Problemen im Gerät führen.However, the other known solution for direct contacting of the busbar by means of an additional plug is obviously more complex and in some cases can also lead to spatial problems in the device.

Die im Patentanspruch 1 angegebene erfindungsgemäße Lösung bietet den besonderen Vorteil einer direkten Kontaktierung der Stromschiene durch eine geringfügige Modifikation bestehender indirekter Kartenstecker, wobei die Erfindung dadurch gekennzeichnet ist daß an wenigstens einer Schmalseite der Kontaktfederleiste des Steckverbinders eine zusätzliche Kontaktfeder eingesetzt ist zur Kontaktierung ener mehreren Steckverbindern zugeordneten Stromschiene über eine Aussparung in der entsprechenden Schmalseite des Schutzkragens der Kontaktfederleiste.The solution according to the invention specified in claim 1 offers the particular advantage of direct contacting of the busbar by a slight modification of existing indirect card plugs, the invention being characterized in that an additional contact spring is used on at least one narrow side of the contact spring strip of the connector for contacting several plug connectors Busbar via a recess in the corresponding narrow side of the protective collar of the contact spring strip.

Vorteilhafte Weiterbildungen des Erfindungsgedankens sind in Unteransprüchen angegeben sowie in der nachfolgenden Beschreibung erläutert.Advantageous developments of the inventive concept are specified in the subclaims and explained in the description below.

Vorteilhaft ist es zur Erhöhung der Kontaktsicherheit an der Stromschiene in der erwähnten Schmalseite der Kontaktfederleiste zwei oder auch mehr zusätzliche elektrisch-galvanisch parallel verbundene Kontaktfedern vorzusehen.To increase the contact reliability on the busbar, it is advantageous to provide two or more additional electrically-galvanically connected contact springs in the aforementioned narrow side of the contact spring strip.

Um für den Steckverbinder gleichzeitig einen Verdrehschutz gegen unbeabsichtigt falsches Zusammenstecken der Kontaktleiste und der Kontaktfederleiste gewährleisten zu können, ist bei einer vorteilhaften Ausführungsform vorgesehen, den oder due zusätzliche (n) Kontaktfeder (n) in einen kammerartigen Vorsprung einzusetzen, der seitlich offen ist und aus der für die Stromschienenkontaktgabe vorgesehenen Schmalseite der Kontaktfederleiste vorspringt und zwar um ein Stück das in etwa der Wandstärke des Schutzkragens der Kontaktleiste entspricht. Am Schutzkragen ist dann eine entsprechende Aussparung vorgesehen, über die der Kontaktgabe-Zugriff des oder der zusätzlichen Kontaktfeder(n) gewährleistet ist.In order to be able to guarantee twist protection for the plug connector against inadvertently incorrect plugging together of the contact strip and the contact spring strip, in an advantageous embodiment it is provided that the additional contact (s) be inserted into a chamber-like projection which is open on the side and off the narrow side of the contact spring strip provided for the contact with the busbar projects by a piece which corresponds approximately to the wall thickness of the protective collar of the contact strip. A corresponding recess is then provided on the protective collar, via which the contacting access of the additional contact spring (s) is ensured.

Die Stromschiene selbst kann in am Gehäuseteil der Messer- oder Stiftkontaktleise angespritzte Kunststoffhaken eingeklipst oder durch zusätzliche mit diesem Gehäuseteil verbundene Federelemente so gehalten sein, daß auf einfache Weise die Höhe der Stromschiene variiert werden kann, um so eine gewünschte Voreilung der Kontaktgabe der Hochstromkontakte gegenüber den Signalkontakten des Steckverbinders sicherzustellen. Die Voreilung der Stromkontaktgabe kann aber auch durch eine unterschiedliche insbesondere etwas größere Länge des oder der zusätzlichen Kontaktfeder (n) erreicht werden.The conductor rail itself can be clipped into plastic hooks molded onto the housing part of the knife or pin contact rail or held by additional spring elements connected to this housing part in such a way that the height of the conductor rail can be varied in a simple manner in order to achieve a desired advance of the contacting of the high-current contacts over the Ensure signal contacts of the connector. The advance of the current contact can also be achieved by a different, in particular somewhat larger, length of the additional contact spring (s).

Nachfolgend wird ein Ausführungsbeispiel der Erfindung unter Bezug auf einen Steckverbinder nach DIN 41 612, Bauform R beschrieben, der erfindungsgemäß mit den seitlichen Zusatzkontakten versehen ist. Es zeigen:

Die Rückwand 1, beispielsweise eines elektronischen Rechengerätes, ist mit einer Mehrzahl von (Messer- oder Stift-) Kontaktleisten 11 bestückt, die in Parallelausrichtung gleichabständig nebeneinander von der Oberseite in die Rückwand eingesetzt sind und deren durch die Rückwand hindurchgehende Kontakstifte unterseitig in hier nicht gezeigter Weise beispielsweise in sogenannter Wickeltechnik verdrahtet sind. Die Kontakstifte 16 einer Kontaktleise 11 sind von einem Schutzkragen 2 umgeben, dessen Innenabmessungen an die Umrandungsmaße einer (in der Darstellung herausgenommenen) Federleiste 6 angepaßt sind, die in bekannter Weise mit einer der Anzahl der Kontakstifte 16 entsprechenden Zahl von (nicht gezeigten) Federkontakten bestückt ist und gleichzeitig zur mechanischen Halterung keweils einer aus einer Mehrzahl von Tochterkarten 5 dient. Eine oder beide Wände des Schutzkragens 2 der Kontaktleiste 11 sind bis auf einen Restabschnitt - den Nocken 7, der in später näher zu beschreibender Weise als Verdrehschutz dient - auf der Schmalseite 10 der Kontaktleiste 11 entfernt, so daß eine Aussparung 9 gebildet ist. Entlang den Schmalseiten 10 verlaufen im dargestellten Beispiel zwei Stromschienen 3, 4, die von der Innenseite des Schutzkragens 2 aus über die Aussparung 9 frei zugänglich, das heißt im Bereich der Aussparung elektrisch kontaktierbar sind. Falls für die Stromversorgung der Tochterkartens 5 nur eine Stromschiene benötigt wird, so kann an jeder Kontaktleiste 11 gegebenenfalls auch nur eine Aussparung 9 bzw. nur ein Nocken 7 vorgesehen sein. Die Stromschienen 3, 4 bilden also im Bereich der Aussparungen 9 den stirnseitigen Abschluß des Schitzkragens 2 der Kontaktleisten 11.The rear wall 1, for example of an electronic computing device, is equipped with a plurality of (knife or pin) contact strips 11, which are inserted in parallel in parallel alignment next to one another from the top into the rear wall and whose contact pins, which pass through the rear wall, are not shown on the underside here Are wired for example in so-called winding technology. The contact pins 16 of a contact track 11 are surrounded by a protective collar 2, the internal dimensions of which are adapted to the outline dimensions of a spring strip 6 (removed in the illustration) which, in a known manner, is equipped with a number of spring contacts (not shown) corresponding to the number of contact pins 16 and at the same time one of a plurality of daughter cards 5 is used for mechanical mounting. One or both walls of the protective collar 2 of the contact strip 11 are removed except for a residual section - the cam 7, which serves as protection against rotation in a manner to be described later - on the narrow side 10 of the contact strip 11, so that a recess 9 is formed. In the example shown, two conductor rails 3, 4 run along the narrow sides 10, which are freely accessible from the inside of the protective collar 2 via the cutout 9, that is to say can be electrically contacted in the area of the cutout. If only one power rail is required for the power supply of the daughter cards 5, then only one cutout 9 or only one cam 7 can be provided on each contact strip 11. The busbars 3, 4 thus form in the region of the cutouts 9 the front end of the collar 2 of the contact strips 11.

Die in Fig. 2 in vergrößerter Perspektiv-Teilansicht gezeigte Federleiste 6 läßt im Bereich der dargestellten Schmalseite 10' in dem in den Schutzkragen 2 eingreifenden Abschnitt zwei vorspringende Seitenwände 14, 15 erkennen, die eine zur Schmalseite 10' offene Kammer bilden, in die im dargestellten Beispiel zwei zusätzliche Kontaktfedern 8 eingesetzt sind, welche über die Aussparung 9 die zugeordnete Kontaktschiene 3 oder 4 kontaktieren. Ersichtlicherweise kann auch lediglich eine Kontaktfeder 8 oder es können mehr als zwei Kontaktfedern vorgesehen sein. Für eine sichere Kontaktierung der zugeordneten Stromschiene 3 oder 4 dürften jedoch in der Regel zwei Kontaktfedern 8 zweckmäßig sein, die unmittelbar und einstückig mit einem oder mehreren Anschlußkontakstift (en) 13 verbunden sind. Der Abstand der beiden Seitenwände 14, 15 der Kammer 12 entspricht der Breite der Aussparung 9 während ein restlicher Stirnwandabschnitt 18 etwa der Breite des Nockens 7 entspricht. Die Außenmaße der Kammerwände 14, 15 im Zusammenwirken mit der Aussparung 9 sowie der restliche Stirnwandabschnitt 18 in Zusammenwirken mit dem Nocken 7 bilden einen "Verwechslungsschutz" bzw. einen Verdrehschutz, so daß immer sichergestellt ist, daß die jeweilige Tochterkarte 5 mit der zugeordneten Federleiste 6 jeweils seitenrichtig in die zugeordnete Kontaktleiste 11 eingesteckt wird.The female connector 6 shown in FIG. 2 in an enlarged perspective partial view shows two projecting side walls 14, 15 in the region of the narrow side 10 'shown in the section engaging in the protective collar 2, which form a chamber open to the narrow side 10' into which Example shown two additional contact springs 8 are used, which contact the associated contact rail 3 or 4 via the recess 9. Obviously, only one contact spring 8 or more than two contact springs can be provided. However, two contact springs 8, which are connected directly and in one piece to one or more connecting contact pin (s) 13, should generally be expedient for reliable contacting of the assigned busbar 3 or 4. The distance between the two side walls 14, 15 of the chamber 12 corresponds to the width of the recess 9, while a remaining end wall section 18 corresponds approximately to the width of the cam 7. The outer dimensions of the chamber walls 14, 15 in cooperation with the recess 9 and the remaining end wall section 18 in cooperation with the cam 7 form a "mix-up protection" or an anti-twist protection, so that it is always ensured that the respective daughter card 5 with the associated female connector 6th is inserted correctly into the associated contact strip 11 in each case.

Die Stromschienen 3, 4 können mittels an dem Schutzkragen 2 bzw. an der Rückwand 1 oder auch am Gehäuse des nicht gezeigten Gerätes angebrachten Kontaktfedern so befestigt sein, daß eine geringfügige Höhenverstellung der Kontakschienen 3, 4, das heißt also senkrecht zur Ebene der Rückwand 1, und damit eine Einstellung der Kontaktgabe-Voreilung der Stromversorgung möglich ist. Die Stromschienen 3, 4 können auch in Aufnahmeschlitze 20 im Isolierkörper der Kontaktleisten 11 eingesetzt werden und durch einen oder zwei unmittelbar an die Kontaktleisten 11 angespritzte Rasthaken 22 bzw. 24, 26 durch Einklipsen fixiert sein (vgl. Fig. 3 und 4).The busbars 3, 4 can be attached by means of contact springs attached to the protective collar 2 or to the rear wall 1 or else to the housing of the device (not shown) in such a way that a slight height adjustment of the contact rails 3, 4, that is to say perpendicular to the plane of the rear wall 1 , and thus an adjustment of the contact lead advance of the power supply is possible. The busbars 3, 4 can also be used in receiving slots 20 in the insulating body of the contact strips 11 and be fixed by one or two snap-in hooks 22 or 24, 26 molded directly onto the contact strips 11 by clipping (see FIGS. 3 and 4).

Eine andere Lösung zur geringfügig höhenverstellbaren Fixierung der Stromschiene 3 bzw. 4 zeigt die Fig. 5° Hier ist die Stromschiene 3 bzw. 4 ebenfalls in stirnseitige Aufnahmeschlitze 20 des Isolierkörpers der Kontaktleiste 11 eingesetzt. Zur Fixierung der Stromschiene 3 bzw. 4 dient eine metallische Klammer 28, welche die Stromschiene 3 bzw. 4 gegen einen am Isolierkörper angespritzten Nocken 30 zieht.Another solution for the slightly height-adjustable fixing of the busbar 3 or 4 is shown in FIG. 5 °. Here, the busbar 3 or 4 is likewise inserted into the front receiving slots 20 of the insulating body of the contact strip 11. A metal bracket 28 is used to fix the busbar 3 or 4, which pulls the busbar 3 or 4 against a cam 30 molded onto the insulating body.
