Description

  • Die Erfindung betrifft eine mehrpolige Steckvorrichtung mit einer auf eine Verdrahtungsplatte aufsetzbaren, der Aufnahme eines Steckers dienenden Zentrierleiste mit einer Schirmvorrichtung, die mit auf Erdpotential liegenden Bereichen eines die Verdrahtungsplatte haltenden Baugruppenträgers elektrisch verbunden ist, bei der die Schirmvorrichtung durch separate Schirmelemente mit parallel zur Steckrichtung ausgerichteten Schirmflächen gebildet ist, die im gesteckten Zustand des Steckers an einer Schirmung des Steckers federnd anliegen The invention relates to a multi-pole plug-in device with an attachable on a wiring board, the receiving a plug serving centering strip with a screen device which is electrically connected to at ground potential areas of the wiring board holding rack, wherein the screen device aligned by separate screening elements with parallel to the insertion direction screen areas is formed, which resiliently bear against a shielding of the plug in the plugged state of the plug
  • Eine derartige Steckvorrichtung ist zB aus dem DE-U-85 17 809 bekannt. Such a connector device is known for example from DE-U-85 17 809th Bei der bekannten Steckvorrichtung ist der Übergabekabelstecker über seine Blechkappen und über Federelemente eines an den Außenflächen der Zentrierleiste anliegendes Schirmelementes mit Erdpotential verbunden. In the known connector device the transfer cable connector is connected to its sheet-metal caps and spring elements of a signal applied to the outer surfaces of the centering shield element to ground potential. Nachteilig daran ist, daß jeweils die gesamte Zentrierleiste abgeschirmt werden muß, und daß sich durch den Einsatz der Schirmelemente die Breite vergrößert, so daß bei einer vollständig mit Kontaktmessern bestückten Verdrahtungsplatte bestimmte Kontaktmesser-Reihen nicht genutzt werden können. A disadvantage is that in each case the entire centering must be shielded, and that the width is enlarged through the use of the shield elements, so that certain contact blade rows can not be used at a fully populated with contact blades wiring board.
  • Aufgabe der vorliegenden Erfindung ist es, eine Steckvorrichtung der eingangs genannten Art so auszubilden, daß die vorgegebene zulässige Teilung für den Einsatz der Zentrierleisten erhalten bleibt und gleichzeitig bei einer flexibleren Schirmung die Schirmableitung gegenüber der bisherigen Steckvorrichtung zu verbessern. The object of the present invention is to construct a plug device of the type mentioned above that the predetermined allowable pitch is maintained for the use of the centering and at the same time to improve the shielding dissipation compared to the previous plug-in device with a flexible shielding.
  • Diese Aufgabe wird erfindungsgemäß für eine Steckvorrichtung der obengenannten Art dadurch gelöst, daß die Zentrierleiste aus einer mit Durchtrittsöffnungen für die Kontaktmesser versehenen Bodenplatte besteht, welche je vorgegebener Längeneinheit in den jeweiligen Eckbereichen winkelförmige Abstandshalter mit im freien Endbereich vorgesehenen Auflagen für die Kontaktmesser aufweist, und daß die Schirmvorrichtung pro vorgegebener Längeneinheit je zwei metallische Längsfederstreifen und zwei metallische Querfederstreifen mit Aussparungen bzw. Haken zum gegenseitigen Halten aufweist, die gleichzeitig den Einlaufbereich für die Teilstecker bilden. This object is achieved for a plug-in device of the above type characterized in that the centering strip comprises a provided with passage openings for the contact blades bottom plate having each predetermined unit of length in the respective corner regions angle-shaped spacers having provided in the free end region of requirements for the contact blades, and in that having the screen device per predetermined unit of length in each case two metallic longitudinal spring strips and two metallic transverse spring strips with cutouts or hooks for mutually holding, which simultaneously form the inlet region for the plug part.
  • Bei der erfindungsgemäßen Steckvorrichtung wird gegenüber der bekannten Steckvorrichtung die Zentrierleiste ohne Außen- und Zwischenwände erstellt, so daß nurmehr der Boden und die Abstandshalter übrig bleiben. In the inventive plug-in device, the centering without external and partition walls, is built over the known plug-in device so that nurmehr the bottom and the spacers remain. Durch das Weglassen der Wände ist es möglich, den entstandenen Platz für die Federstreifen sowohl längs als auch quer zwischen den zu steckenden Kabelsteckern zu nutzen, ohne daß eine Teilung verloren geht Darüber hinaus kann die Schirmung bei der erfindungsgemäßen Steckvorrichtung flexibel vorgenommen werden, dh es muß nicht unbedingt die Zentrierleiste über ihre gesamte Länge geschirmt werden. By omitting the walls, it is possible to use the resulting space for the spring strips both longitudinally and transversely between the to be plugged cable connectors without a partition is lost Moreover, the shield can be made flexible in the inventive plug device, ie it must not necessarily the centering be shielded over its entire length. Es ist möglich nur dort eine Schirmung vorzusehen, wo eine solche unbedingt notwendig ist. It is only there to provide a shield where such is absolutely necessary. Ein weiterer Vorteil der erfindungsgemäßen Steckvorrichtung besteht darin, daß die Schirmwirkung bedeutend erhöht wird, da auch jeweils querliegende Schirmungen vorgesehen sind. Another advantage of the connector according to the invention is that the shielding effect is significantly increased, since each transverse shields are provided.
  • Eine zweckmäßige Ausgestaltung der erfindungsgemäßen Steckvorrichtung ist dadurch gekennzeichnet, daß die Federstreifen aus zwei miteinander verbundenen Blechen bestehen, wobei jedes Blech in seinem mittleren Bereich durch Freischnitte erzeugte und an ihrem freien Ende abgewinkelte Federzungen aufweist. An advantageous embodiment of the connector according to the invention is characterized in that the spring strips comprise two interconnected metal sheets, said each sheet in its middle region generated by free cuts and bent at its free end resilient tongues. Hierdurch wird eine gute Kontaktierung mit den Schirmblechen der Kabelstecker erreicht. This makes good contact is achieved with the shield plates of the cable connector. Gleichzeitig wird durch diese Ausführung eine genügend große Steifigkeit zum Einpressen der Federstreifen erreicht. At the same time a sufficient stiffness is achieved for pressing in the spring strip by this execution.
  • Weitere vorteilhafte Ausgestaltungen der erfindungsgemäßen Steckvorrichtung ergeben sich aus den Unteransprüchen. Further advantageous embodiments of the connector according to the invention result from the dependent claims.

  • In FIG 1 ist ein Schnitt durch eine mehrpolige Steckvorrichtung gemäß der vorliegenden Erfindung dargestellt. In FIG 1, a section through a multi-pole plug-in device according to the present invention. Auf der einen Seite der Rückwandverdrahtungsplatte 1, in der die Kontaktmesser 4 gehalten sind, wird ein Kabelstecker 7 aufgeschoben, während auf der anderen Seite eine Baugruppe auf die Kontaktmesser 4 aufgeschoben wird. On one side of the rear wall wiring plate 1, in which the contact blades 4 are held, a cable connector 7 is pushed, during an assembly of the contact blade 4 is pushed onto the other side. In die Öffnungen für die Kontaktmesser werden, wenn eine entsprechende Schirmung gewünscht wird, die metallischen Federstreifen 5 und 6 mittels der Einpreßzinken 15 eingedrückt. , The metallic spring strips are if a corresponding shielding is desired in the openings for the contact blades, pressed 5 and 6 by means of Einpreßzinken 15th
  • Der Aufbau der metallischen Längsfederstreifen 5 sowie der metallischen Querfederstreifen 6 ergibt sich aus der FIG 4. Die Federstreifen bestehen aus zwei zB 0,3 mm dicken Metallbändern, die im Endzustand verlötet oder auch punktgeschweißt sind. The structure of the metallic longitudinal spring strips 5 and the metallic transverse spring strips 6 resulting from the FIG 4. The spring strips are made of two 0.3 mm thick, for example, metal strips, which are soldered or spot-welded in the final state also. Hierdurch wird sowohl eine genügend große Steifigkeit zum Einpressen erreicht, als auch die Möglichkeit geschaffen, an der gleichen Stelle die Federn beidseitig anzuordnen Die Enden der Federstreifen 5 und 6 haben Aussparungen 10 bzw Haken 9, in denen sie sich gegenseitig verhaken und somit im ungünstigsten Fall eine Auslenkung durch. In this way, both a sufficient stiffness as well as the possibility is achieved for pressing, provided to be located at the same place the springs on both sides have the ends of the spring strips 5 and 6, recesses 10 or hook 9, in which they are entangled with each other and thus in the worst case a deflection by. die einzelnen Federkräfte von einer Blechdicke (im vorliegenden Fall von 0,3 mm) zulassen. Allow the individual spring forces of a sheet thickness (in this case 0.3 mm). Durch die auf eine Teileinheit beschränkten Längen lassen sich die Fertigungstoleranzen für die Einpreßpins fertigungstechnisch gut einhalten. By limited to a sub-unit lengths, the manufacturing tolerances for the press-fit pins can meet manufacturing technology well. Gleichzeitig wird dadurch ein modularer Aufbau gewährleistet. At the same time characterized a modular construction is ensured. Es ist nicht mehr notwendig die ganze Zentrierleiste zu schirmen, vielmehr können gezielt bestimmte Teileinheiten abgeschirmt werden. It is no longer necessary to protect the whole centering, but target specific sub-units can be shielded. Von den zwei Längsfederstreifen und den zwei Querfederstreifen wird die Einlauföffnung für die Teilkabelstecker 7 gebildet, so daß eine gute Verbindung zwischen den metallischen Federstreifen und dem Schirmblech 3 (siehe FIG 6) des Kabelsteckers gegeben ist. Of the two longitudinal spring strips and two transverse spring strips the inlet opening for the supply cable connector 7 is formed so that a good connection between the metal spring strip and the screen plate 3 (see FIG 6) of the cable plug is provided. Mittels Rastfedern 16, die in entsprechende Ausnehmungen des Kabelstecker-Schirmblechs eingreifen, sind die Kabelstecker 7 gegen Herausfallen gesichert. By means of detent springs 16 which engage in corresponding recesses of the cable connector shroud, the cable connector 7 are secured against falling out.
  • FIG 5 zeigt den Aufbau der Zentrierleiste, welche bei der erfindungsgemäßen Steckvorrichtung nur noch aus der Bodenplatte 12 und den Abstandshaltern 11 besteht. 5 shows the structure of the centering strip, which consists in the inventive plug-in device only from the bottom plate 12 and the spacers. 11 Dadurch liegt die Zentrierleiste 2 mit den Auflagen 13 auf den Spitzen der Kontaktmesser 4 auf, womit ein definierter Abstand zur Ruckwandverdrahtungsplatte 1 gewährleistet ist. Characterized lies the centering strip 2 with the pads 13 on the tips of the contact blades 4, thus ensuring a defined distance from the rear wall wiring board. 1 Zusätzlich ist die Zentrierleiste 2 durch hier nicht dargestellte verdrehbare Scheibchen in der Bodenplatte auf den Messern gehalten. In addition, the centering is retained by means not shown here rotatable discs in the bottom plate to the blades. 2 Vorstellbar wäre aber auch ein Einschnappen in die Federstreifen. but imagine would be a snap in the spring strips.
