Definitions
- the invention relates to a shield device for a plug connector of a backplane of a module frame, the shield device along the side walls of a connector housing having shield plates perpendicular to the backplane, which are connected to a shield position of the backplane.
- Such a screen device is e.g. made known by DE-U-92 05 780.2.
- the shield plates are provided with pin-like projections which can be pressed into holes in the circuit board. It is customary to design these bores as plated-through holes which are connected to the ground layers of the printed circuit board. This creates a close shield contact between the shield plate and the ground layers.
- the shield plates have a plurality of spring tongues standing in the plugging direction, which can be connected to a shield housing of an attachable mating connector.
- the spring tongues are punched out of the shield plate and bent towards the side walls of the connector housing. This results in breakthroughs in the shield plate, which can impair its shielding effect. But there is also a gap between the shield plate and the outer wall of the attached shield housing, which can further reduce the shielding effect.
- the invention is based on the rises to improve the shielding security of the rear wall connector.
- the contact spring strip enables the shield plate to be formed without openings. It can work with a variety of closely adjacent spring tongues are provided which result in a large number of decoupled contacts and which close the gap between the plug-in shield housing of the mating connector and the shield plate in a high-frequency-tight manner.
- the contact spring strip can be designed in terms of its shape and nature so that it has optimal spring and contact properties.
- the spring plate can therefore be provided with a higher rigidity.
- the mating connector can then be guided and supported on the shield plate with its shield housing, which increases the contact reliability of the plug connection.
- the contact spring strip according to claims 3 and 4 can be easily manufactured and results in a high stability of the spring tongues even in the lateral direction. This makes it possible to fix the contact spring strip on the shield plate on the side facing away from the mating connector, without the other ends of the spring tongues being damaged or bent when the shield housing is inserted. Spot welding creates very good contact between the contact spring strip and the shield plate on the side facing the ground layers of the printed circuit boards. This allows the interference currents to be diverted to the ground layers in the shortest possible way.
- the development according to claim 5 ensures that the shield housing of the mating connector is not on the upper edges of the contact spring strip and damage it.
- the postage clearances according to claim 7 create favorable attachment areas for the insertion tool in the region of the double bend.
- the advantages of the shielding device can be used in particular for cable connectors which can be plugged on at the rear and which are exposed to external mechanical influences and are therefore subject to considerably greater loads in terms of their guiding and contact properties than the modules which are plugged on at the front.
- the transverse shield plates according to claim 9 can e.g. be arranged along the short end walls of the connector housing. However, there is also the possibility of arranging several of these transverse shield plates one behind the other at shorter intervals. It is then possible to put several short mating connectors in a row on the connector. For the inner cross plates, it is then advisable to attach the contact spring strips on both sides.
- bevels are formed on the contact spring strips which are steplessly bulged from the shield plate to the shield housing. This prevents the contact spring strips from being caught and damaged by the shield housing when the mating connector is plugged on. The rags close the frankings, which improves the shielding effect of the transverse shielding plates.
- a connector 1 is provided with a shield housing 2, which is placed on the outside of a backplane 3.
- the plug connector 1 is provided with plug pins 4 which protrude through the rear wall circuit board 3 and on the inside of which plug-in plug-in modules 5 can be contacted.
- Shield plates 7 are arranged along side walls 6 of the plug housing 2 and are pressed into through-bores of the rear wall circuit board 3 with pin-like projections 13. This is e.g. formed as a multi-layer plate which has closed ground layers on the outside, which are connected to the plated-through holes.
- contact spring strips 8 are attached which are provided with a bulge perforated by transverse slots 9 towards the side walls 6. Between the transverse slots 9 there are spring tongues which extend in the insertion direction of a mating connector (not shown in more detail), the shield housing 11 of which is indicated by dash-dotted lines and stands directly above the side walls 6. The shield housing 11 with the mating connector can be pushed over the side walls 6 in the direction indicated by the arrow and is then contacted with the bulges of the spring tongues 10. These are supported at their two ends on the shield plate 7.
- the spring tongues 10 are held on their side facing the backplane 3 on a connecting web 11 which e.g. is attached to the shield plate 7 by spot welding. At the opposite ends of the spring tongues 10, these are connected to one another by thin transverse webs 12, which are slidably supported on the shield plate 7.
- the bulge is so high that the distance between the spring tongues 10 of the outer wall 6 is smaller than the thickness of the shield housing 11, which ensures reliable contact.
- the shield plate 7 has over the crossbars 12 of the contact spring strip 8, a double bend 14, which covers the outer edge of the contact spring strip 8 in the manner of a crank, so that the upper longitudinal edge of the contact spring strip 8 can not be detected by the shield housing 11 attached.
- the shield plate 7 is formed closed in the area of the contact spring strip 8.
- the spring tongues 10 are strung together so closely that they close the gap between the shield plate 7 and the shield housing 11 in a high-frequency-tight manner.
- the shield plates 17, 18 according to FIGS. 3 to 6 have a crenellated shape on their side facing away from the projections 13 Clearances 23, into which, closing these, protruding flaps 24 of the contact spring strips 19, 20 complementary. These tabs run in the direction of curvature of the arcuate bulges of the contact spring strips 19, 20 obliquely into the clearances 23, whereby the upper edges of the tabs 24 lie in the overlap area of the shield plates (17, 18) and cannot be detected by the shield housing of the cable connector to be plugged on.
- the inner shield plates 17 arranged between the end faces of the connector have contact spring strips on both sides which are bent in one piece around the lower edge of the shield plate 17 facing the projections 13. Their tabs 24 projecting into the franking 23 are halved in width and alternately protrude into the frankings 23 from one side and the other side.

Description
Die Erfindung bezieht sich auf eine Schirmeinrichtung für einen Steckverbinder einer Rückwandleiterplatte eines Baugruppenrahmens, wobei die Schirmeinrichtung entlang den Seitenwänden eines Steckergehauses senkrecht zur Rückwandleiterplatte stehende Schirmbleche aufweist, die mit einer Schirmlage der Rückwandleiterplatte verbunden sind.The invention relates to a shield device for a plug connector of a backplane of a module frame, the shield device along the side walls of a connector housing having shield plates perpendicular to the backplane, which are connected to a shield position of the backplane.
Eine derartige Schirmeinrichtung ist z.B. durch DE-U-92 05 780.2 bekannt geworden. Danach sind die Schirmbleche mit stiftartigen Vorsprüngen versehen, die in Bohrungen der Leiterplatte einpreßbar sind. Es ist Üblich, diese Bohrungen als Durchkontaktierungen auszubilden, die mit den Masselagen der Leiterplatte in Verbindung stehen. Dadurch ist zwischen dem Schirmblech und den Masselagen ein enger Schirmkontakt hergestellt.Such a screen device is e.g. made known by DE-U-92 05 780.2. Then the shield plates are provided with pin-like projections which can be pressed into holes in the circuit board. It is customary to design these bores as plated-through holes which are connected to the ground layers of the printed circuit board. This creates a close shield contact between the shield plate and the ground layers.
Die Schirmbleche weisen eine Vielzahl von in der Steckrichtung stehenden Federzungen auf, die mit einem Schirmgehause eines aufsteckbaren Gegensteckers verbindbar sind. Die Federzungen sind aus dem Schirmblech freigestanzt und zu den Seitenwanden des Steckergehäuses hin ausgebogen. Dabei ergeben sich Durchbrüche im Schirmblech, die dessen Schirmwirkung beeintrachtigen können. Aber auch zwischen dem Schirmblech und der Außenwand des aufgesteckten Schirmgehäuses ergibt sich ein Spalt, der Schirmwirkung noch weiter verringern kann.The shield plates have a plurality of spring tongues standing in the plugging direction, which can be connected to a shield housing of an attachable mating connector. The spring tongues are punched out of the shield plate and bent towards the side walls of the connector housing. This results in breakthroughs in the shield plate, which can impair its shielding effect. But there is also a gap between the shield plate and the outer wall of the attached shield housing, which can further reduce the shielding effect.
Der Erfindung liegt die Aufgahe zugrunde, die Schirmsicherheit des Rückwandsteckverbinders zu verbessern.The invention is based on the rises to improve the shielding security of the rear wall connector.
Diese Aufgabe wird durch die Erfindung gemäß Anspruch 1 gelöst. Der Kontaktfederstreifen ermöglicht es, das Schirmblech ohne Durchbrüche auszubilden. Er kann mit einer Vielzahl von eng benachbarten Federzungen versehen sein, die eine Vielzahl voneinander entkoppelter Kontakte ergeben und die den Spalt zwischen dem aufgesteckten Schirmgehäuse des Gegensteckers und dem Schirmblech hochfrequenzdicht verschließen.This object is achieved by the invention according to claim 1. The contact spring strip enables the shield plate to be formed without openings. It can work with a variety of closely adjacent spring tongues are provided which result in a large number of decoupled contacts and which close the gap between the plug-in shield housing of the mating connector and the shield plate in a high-frequency-tight manner.
Der Kontaktfederstreifen kann hinsichtlich seiner Form und Beschaffenheit so gestaltet werden, daß er optimale Feder- und Kontakteigenschaften aufweist. Das Federblech kann daher mit einer höheren Steifigkeit versehen werden. Der Gegenstecker kann dann mit seinem Schirmgehäuse zusätzlich am Schirmblech geführt und abgestützt werden, was die Kontaktsicherheit der Steckverbindung erhöht.The contact spring strip can be designed in terms of its shape and nature so that it has optimal spring and contact properties. The spring plate can therefore be provided with a higher rigidity. The mating connector can then be guided and supported on the shield plate with its shield housing, which increases the contact reliability of the plug connection.
Vorteilhafte Weiterbildungen der Erfindung sind in den Ansprüchen 2 bis 8 gekennzeichnet:Advantageous developments of the invention are characterized in claims 2 to 8:
Durch die doppelseitige Abstützung der Federzungen nach Anspruch 2 kann bei geringer Materialdicke eine hohe Kontaktkraft zwischen dem aufgesteckten Schirmgehäuse und den Federzungen erzielt werden. Außerdem wird dadurch die Anzahl der Kontaktstellen zwischen dem Kontaktfederstreifen und dem Schirmbleche verdoppelt.Due to the double-sided support of the spring tongues according to claim 2, a high contact force can be achieved between the attached shield housing and the spring tongues with a small material thickness. In addition, the number of contact points between the contact spring strip and the shield plates is doubled.
Der Kontaktfederstreifen nach den Ansprüchen 3 und 4 läßt sich einfach herstellen und ergibt eine hohe Stabilität der Federzungen auch in seitlicher Richtung. Dadurch ist es möglich, den Kontaktfederstreifen auf der dem Gegenstecker abgewandten Seite am Schirmblech festzulegen, ohne daß die anderen Enden der Federzungen beim Einstecken des Schirmgehäuses beschädigt oder verbogen werden. Durch das Punktschweißen wird ein sehr guter Kontakt zwischen dem Kontaktfederstreifen und dem Schirmblech auf der den Masselagen der Leiterplatten zugewandten Seite hergestellt. Dadurch können die Störströme auf kürzestem Weg auf die Masselagen abgeleitet werden.The contact spring strip according to claims 3 and 4 can be easily manufactured and results in a high stability of the spring tongues even in the lateral direction. This makes it possible to fix the contact spring strip on the shield plate on the side facing away from the mating connector, without the other ends of the spring tongues being damaged or bent when the shield housing is inserted. Spot welding creates very good contact between the contact spring strip and the shield plate on the side facing the ground layers of the printed circuit boards. This allows the interference currents to be diverted to the ground layers in the shortest possible way.
Durch die Weiterbildung nach Anspruch 5 wird sichergestellt, daß das Schirmgehäuse des Gegensteckers nicht auf die Oberkanten des Kontaktfederstreifens treffen und diesen beschädigen kann.The development according to claim 5 ensures that the shield housing of the mating connector is not on the upper edges of the contact spring strip and damage it.
Die Weiterbildung nach Anspruch 6 ermöglicht eine sichere Kontaktierung mit den Federzungen und gleichzeitig eine enge Führung des Schirmgehäuses an den Außenwänden des Steckergehauses.The development according to claim 6 enables reliable contacting with the spring tongues and at the same time tight guidance of the shield housing on the outer walls of the connector housing.
Durch die Freimachungen nach Anspruch 7 werden günstige Ansatzflächen für das Eindrückwerkzeug im Bereich der Doppelbiegung geschaffen.The postage clearances according to claim 7 create favorable attachment areas for the insertion tool in the region of the double bend.
Die Vorteile der Schirmeinrichtung lassen sich besonders für rückseitig aufsteckbare Kabelstecker nach Anspruch 8 nutzen, die äußeren mechanischen Einwirkungen ausgesetzt sind und somit hinsichtlich ihrer Führungs- und Kontakteigenschaften erheblich starker belastet sind, als die frontseitig aufgesteckten Baugruppen.The advantages of the shielding device can be used in particular for cable connectors which can be plugged on at the rear and which are exposed to external mechanical influences and are therefore subject to considerably greater loads in terms of their guiding and contact properties than the modules which are plugged on at the front.
Die querstehenden Schirmbleche nach Anspruch 9 können z.B. entlang den kurzen Stirnwänden des Steckergehauses angeordnet sein. Es besteht aber auch die Möglichkeit, mehrere dieser querstehenden Schirmbleche in kürzeren Abständen hintereinanderliegend anzuordnen. Es ist dann möglich, mehrere kurze Gegenstecker hintereinandergereiht auf den Steckverbinder aufzustecken. Für die inneren Querbleche empfiehlt es sich dann, zu deren beiden Seiten die Kontaktfederstreifen anzubringen.The transverse shield plates according to
Durch die zinnenförmigen Freimachungen und die komplementären Lappen nach Anspruch 10 werden an den Kontaktfederstreifen Einlauf schrägen gebildet, die stufenlos vom Schirmblech ausgehend zum Schirmgehäuse hin ausgebaucht sind. Dadurch wird verhindert, daß die Kontaktfederstreifen beim Aufstecken des Gegensteckers vom Schirmgehäuse erfaßt und beschädigt werden können. Dabei verschließen die Lappen die Freimachungen, wodurch die Schirmwirkung der querstehenden Schirmbleche verbessert wird.Due to the crenellated frankings and the complementary tabs according to
Durch die Weiterbildung nach Anspruch 11 wird für zwei benachbart einsteckbare Kabelstecker nur ein Schirmblech benötigt. Die beiden Kontaktfederstreifen sind kostengünstig einstückig mit einander verbunden und am schirmblech befestigt, was z.B. den Aufwand für die erforderlichen Punktschweißungen verringert.Due to the development according to claim 11, only one shield plate is required for two adjacent plug-in cable connectors. The two contact spring strips are inexpensively connected to one another and attached to the shield plate, which e.g. reduces the effort for the required spot welds.
