Abstract

To provide a simple connection between the screened casing (4) and the strip body (1), the spring-loaded side sections (17a to 17d) of the screened casing (4) having firstly inwardly and then outwardly bent spring arms (18a, 18b) are slid over leading and sliding ramps (22) on the strip body (1) and automatically engaged on its plug-in side (front). The adjacent spring arms of each side section (17a to 17d) alternately form contact components (18b) for providing contact between the screen and an assembly plate (11) or sliding and engagement components (18a) to secure the screened casing (4) to the strip body (1). The invention is suitable for motor vehicle filter plug connectors (9, 10).

Ein derartiger Filter-Steckverbinder ist durch das DE-U-90 05 597 bekannt. Bei diesem Steckverbinder wird das Schirmgehäuse über federnde Seitenteile am Leistenkörper befestigt, welche über die Seitenwände des Leistenkörpers greifen und mit abgewinkelten Randabschnitten an dessen Vorderseite verrasten. Dabei werden die Randabschnitte nach dem Aufschieben des Schirmgehäuses auf den Leistenkörper in einem eigenen Arbeitsgang nach innen abgewinkelt und verrastet. Außerdem sind an den Randabschnitten entlang den Seitenwänden des Leistenkörpers verlaufende Federarme angeformt, welche von dem Leistenkörper weg aufgebogen sind und beim Einbau des Steckverbinders auf einer Montageplatte ohne zusätzliche Maßnahmen eine Kontaktierung bzw. Masseverbindung ergeben. Auf diese Weise wird bei dem bekannten Steckverbinder eine im allgemeinen gut brauchbare Befestigung des Schirmgehäuses bei gleichzeitig mit dem Einbau herstellbarer Masseverbindung erreicht. Unter gewissen Umständen,z.B. bei Überschreitung der Minus-Toleranzen in der Dicke einer Montageplatte, kann die an sich zuverlässige Schirmkontaktierung jedoch ungünstig beeinflußt werden.Such a filter connector is known from DE-U-90 05 597. In this connector, the shield housing is attached to the strip body via resilient side parts, which grip over the side walls of the strip body and engage with angled edge sections on its front side. After pushing the screen housing onto the last body, the edge sections are angled inwards and locked in a separate work step. Also are on the edge sections Spring arms extending along the side walls of the strip body are formed, which are bent away from the strip body and, when the connector is installed on a mounting plate, result in contact or ground connection without additional measures. In this way, in the known connector, a generally usable fastening of the shield housing is achieved with a ground connection that can be produced at the same time as the installation. Under certain circumstances, for example when the minus tolerances in the thickness of a mounting plate are exceeded, the shield contact, which is reliable per se, can be adversely affected.

Der Erfindung liegt die Aufgabe zugrunde, bei einem Filter-Steckverbinder der eingangs genannten Art eine noch kostengünstigere Befestigung des Schirmgehäuses zu erreichen und die Sicherheit der Schirmkontaktierung zu erhöhen.The object of the invention is to achieve an even more cost-effective fastening of the shield housing in a filter connector of the type mentioned at the outset and to increase the safety of the shield contact.

Diese Aufgabe wird erfindungsgemäß durch folgende Merkmale gelöst:

  • a) die Abwinkelungen der federnden Seitenteile des Schirmgehäuses sind als einzelne, voneinander beabstandete und zueinander parallele Federarme ausgebildet,

  • d) die Kontaktelemente sind schräg zur Steckrichtung nach innen gebogen,
  • e) die Gleit- und Rastelemente sind rechtwinklig von den Seitenteilen nach innen gebogen, mit einem Rastorgan versehen und an ihrem freien Ende unter Bildung eines Radius quer zur Steckrichtung zurückgebogen,
  • f) die Seitenwände des Leistenkörpers sind mit Vertiefungen für die Kontaktelemente und mit Auflauf- und Gleitschrägen für die Gleit- und Rastelemente zwecks Aufweitung der Seitenteile beim Verbinden Von Schirmgehäuse und Leistenkörper ausgebildet,
  • g) die Gleit- und Rastelemente sind nach Überwindung der Auflauf- und Gleitschrägen nach innen federnd mit ihrem Rastorgan selbsttätig an den Rastorganen der Vorderseite des Leistenkörpers verrastet.
This object is achieved according to the invention by the following features:
  • a) the bends of the resilient side parts of the shield housing are designed as individual, spaced apart and mutually parallel spring arms,
  • b) all spring arms are bent inwards from the edge of the side parts,
  • c) the spring arms of each side part lying next to one another alternately form contact elements for contacting the shield housing on a mounting plate or sliding and locking elements for connecting the shield housing to the strip body,
  • d) the contact elements are bent inwards at an angle to the direction of insertion,
  • e) the sliding and locking elements are bent inwards at right angles from the side parts, provided with a locking element and bent back at their free end to form a radius transverse to the direction of insertion,
  • f) the side walls of the strip body are formed with recesses for the contact elements and with run-up and sliding bevels for the sliding and locking elements for the purpose of widening the side parts when connecting the screen housing and strip body,

Bei dem Schirmgehäuse eines derartigen Filter-Steckverbinders sind die Abwinkelungen der federnden Seitenteile als Federarme ausgebildet, die alle nach innen gebogen sind, wobei abwechselnd Gleit- und Rastelemente zur Verbindung des Schirmgehäuses mit dem Leistenkörper bzw. Kontaktelemente zur Ankontaktierung des Schirmgehäuses an einer Montageplatte gebildet sind. Außerdem ist der Leistenkörper mit Auflauf- und Gleitschrägen ausgebildet. Beim Aufstecken eines Schirmgehäuses auf einen Leistenkörper bzw. beim Einstecken des Leistenkörpers in ein Schirmgehäuse treffen die Gleit- und Rastelemente auf die Auflauf- und Gleitschrägen, wodurch die federnden Seitenteile des Schirmgehäuses ohne Hilfsmittel selbsttätig aufgeweitet werden. Nach Überwindung der Seitenwände des Leistenkörpers, d.h. wenn die Gleit- und Rastelemente über eine Endkante der Seitenwände an der Vorderseite des Leistenkörpers geschoben werden, federn die Seitenteile des Schirmgehäuses und damit die Gleit-und Rastelemente wieder nach innen, wobei sie mit ihrem Rastorgan selbsttätig an den Rastorganen der Vorderseite des Leistenkörpers verrasten. Dadurch wird das Schirmgehäuse bei dem erfindungsgemäßen Filter-Steckverbinder durch Selbstverrastung und ohne eigenen Arbeitsgang am Leistenkörper fixiert, wodurch eine noch kostengünstigere Befestigung des Schirmgehäuses erreicht wird. Durch die schräg zur Steckrichtung nach innen gebogenen Kontaktelemente wird auch bei ungünstigen Toleranzverhältnissen in der Dicke einer Montageplatte eine toleranzunabhängigere zuverlässige Schirmkontaktierung gewährleistet.In the shield housing of such a filter connector, the bends of the resilient side parts are designed as spring arms, all of which are bent inwards, with alternating sliding and latching elements for connecting the shield housing to the strip body or contact elements for contacting the shield housing on a mounting plate . In addition, the last body is designed with ramp and sliding bevels. When a shield housing is attached to a strip body or when the strip body is inserted into a shield housing, the sliding and latching elements meet the run-up and sliding bevels, whereby the resilient side parts of the shield housing are automatically expanded without aids. After overcoming the side walls of the last body, ie when the sliding and latching elements are pushed over an end edge of the side walls on the front of the last body, the side parts of the shield housing and thus the sliding and latching elements spring back inwards, and they automatically engage with their latching element the locking elements on the front of the last body latch. As a result, the shield housing in the filter connector according to the invention is fixed to the strip body by self-locking and without a separate operation, as a result of which the shield housing is fastened even more cost-effectively. The contact elements, which are bent inwards at an angle to the plug-in direction, ensure reliable tolerance contact independent of the tolerance even in the case of unfavorable tolerance conditions in the thickness of a mounting plate.

Bei dem erfindungsgemäßen Filter-Steckverbinder sind alle Federarme des Schirmgehäuses nach innen gebogen. Dies ist in montagetechnischer Hinsicht von besonderem Vorteil. Der Filter-Steckverbinder kann dann nämlich sowohl in Steckrichtung als auch in hierzu senkrechten Richtungen, alsobezogen auf die Steckrichtung - von der Seite her, problemlos auf eine Montageplatte, z.B. auf eine Geräte frontplatte, zugeführt werden.In the filter connector according to the invention, all spring arms of the shield housing are bent inwards. This is of particular advantage in terms of assembly technology. The filter connector can then easily on the mounting plate, e.g. in the plugging direction as well as in directions perpendicular to it, as related to the plugging direction - from the side. on a device front panel.

Zweckmäßigerweise sind bei einem erfindungsgemäßen Filter-Steckverbinder die Seitenwände des Leistenkörpers entsprechend der Anordnung der Federarme des Schirmgehäuses abwechselnd mit der Form der Kontaktelemente angepaßten Vertiefungen und mit Auflauf-und Gleitschrägen ausgebildet. Dadurch ist der Leistenkörper an seinen Seitenwänden der Gestaltung des Schirmgehäuses angepaßt und somit in vorteilhafter Weise für eine Verbindung mit dem Schirmgehäuse zu einer Einheit ausgebildet.In the case of a filter plug connector according to the invention, the side walls of the strip body are expediently designed in accordance with the arrangement of the spring arms of the shield housing, alternately with depressions adapted to the shape of the contact elements and with run-up and sliding bevels. As a result, the strip body on its side walls is adapted to the design of the shield housing and is thus advantageously designed to be connected to the shield housing to form a unit.

Im Hinblick auf eine besonders einfache, kostengünstige und sichere Halterung sowohl der Ferritkernanordnung als auch des Filterelementes ist es vorteilhaft, wenn die die offene Kammer des Leistenkörpers abdeckende Bodenfläche des Schirmgehäuses mit einem zentrisch angeordneten, rechteckförmigen Ausschnitt mit an zwei einander gegenüberliegenden Längsseiten angeordneten, in der Abwicklung des Schirmgehäuses zunächst in einer Ebene liegenden und aufeinander gerichteten, zueinander parallelen Stegen und Spießen versehen ist. Die Halterung erfolgt dann einfach dadurch, daß die Stege zur Halterung der Ferritkernanordnung schräg zur Bodenfläche nach innen und die Spieße zum Aufstecken des Filterelementes senkrecht zur Bodenfläche nach außen gebogen sind. Aufgrund der Federwirkung der Stege läßt sich eine spielfreie Befestigung der Ferritkernanordnung in der Kammer des Leistenkörpers sicherstellen. Die Anordnung der Spieße ermöglicht eine montagefreundliche Befästigdng des Filterelementes.With regard to a particularly simple, inexpensive and secure mounting of both the ferrite core arrangement and the filter element, it is advantageous if the bottom surface of the shield housing covering the open chamber of the strip body has a centrally arranged, rectangular cut-out with two longitudinal sides arranged opposite one another, in which completion the screen housing is initially provided in one plane and facing each other, parallel webs and spears. The mounting then takes place simply in that the webs for mounting the ferrite core arrangement are bent inwards at an angle to the base surface and the spikes for mounting the filter element are bent outwards perpendicularly to the base surface. Due to the spring action of the webs, a play-free fastening of the ferrite core arrangement in the chamber of the last body can be ensured. The arrangement of the skewers enables the filter element to be attached easily.

Die Verrastung des Schirmgehäuses am Leistenkörper wird bei einem erfindungsgemäßen Filter-Steckverbinder in vorteilhafter Weise dadurch unterstützt, daß aus der die offene kammer des Leistenkörpers abdeckenden Bodenfläche des Schirmgehäuses symmetrisch in Bezug auf die Mitte der Bodenfläche angeordnete Federarme gerissen und schräg zur Bodenfläche nach innen gebogen sind. Diese Federarme wirken der Einsteckrichtung des Leistenkörpers entgegen und führen damit zu einer sicheren Verrastung des Schirmgehäuses.The locking of the shield housing on the strip body is supported in a filter connector according to the invention in an advantageous manner in that spring arms arranged symmetrically with respect to the center of the bottom surface of the shield housing covering the open chamber of the strip body are torn and bent inwards at an angle to the bottom surface . These spring arms counteract the direction of insertion of the last body and thus lead to a secure locking of the umbrella housing.

Schließlich ist es im Hinblick auf eine weitere Kostenoptimierung bei einem erfindungsgemäßen Filter-Steckverbinder vorteilhaft, wenn das Filterelement auf einem Leiterplatten-Trägermaterial ausgebildet ist. Ein derartiger Leiterplattenfilter ist kostengünstiger als ein Planarfilter mit einem Keramiksubstrat und läßt sich infolge der vorteilhaften Befestigungsmöglichkeit am Schirmgehäuse einfacher von der Rückseite des Leistenkörpers her bzw. an dessen Anschlußseite montieren.Finally, with regard to a further cost optimization in a filter connector according to the invention, it is advantageous if the filter element is formed on a printed circuit board carrier material. Such a circuit board filter is less expensive than a planar filter with a ceramic substrate and, owing to the advantageous fastening option on the shield housing, can be mounted more easily from the back of the strip body or on its connection side.

Weitere vorteilhafte Ausgestaltungen des Gegenstandes des Anspruchs 1 sind in den übrigen Unteransprüchen angegeben.Further advantageous embodiments of the subject matter of claim 1 are specified in the remaining subclaims.

Der Filter-Steckverbinder nach den Fig. 1 bis 4 besitzt einen Leistenkörper 1 aus Isoliermaterial, z.B. aus Kunststoff, der im einzelnen in den Fig. 5 bis 8 dargestellt ist. Der Leistenkörper 1 bildet mit seinen Seitenwänden 16 eine zur Anschlußseite (Rückseite) hin offene Kammer 2 (Fig.7) zur Aufnahme einer Ferritkernanordnung 3. Die Kammef 2 wird durch ein in den Fig. 9 bis 13 im einzelnen gezeigtes Schirmgehäuse 4 abgeschlossen. Ferner weist der Leistenkörper 1 eine Anzahl von parallelen, in einem Raster angeordneten Steckerstiften 5 auf, welche von der Anschlußseite her durch Löcher 15 eines Filterelementes 6 (Fig.2) und einen Ausschnitt 7 des Schirmgehäuses 4 in die Kammer 2 eintreten und durch den Boden 8 der Kammer zur Steckseite (Vorderseite) des Filter-Steckverbinders geführt sind, wo sie freie Steckerenden 5a zur Verbindung mit einer Steckerbuchse bilden. Die freien Steckerenden 5a sind von einem an dem Leistenkörper 1 angeformten Kragen 9 umgeben, der an seiner Außenseite Rastelemente 10 zur Verrastung an einer Montageplatte 11, z.B. einer Frontplatte eines Gerätes, aufweist. An der Anschlußseite (Rückseite) sind die Steckerstifte 5 mit ihren Abschnitten 5b etwa rechtwinklig abgebogen und mit einer Schaltungsplatte 12 verlötet (Fig.3).The filter connector according to FIGS. 1 to 4 has a strip body 1 made of insulating material, for example made of plastic, which is shown in detail in FIGS. 5 to 8. The strip body 1 forms with its side walls 16 a chamber 2 open towards the connection side (rear side) (Fig. 7) for receiving a ferrite core arrangement 3. The comb 2 is closed by a shield housing 4 shown in FIGS. 9 to 13 in detail. Furthermore, the strip body 1 has a number of parallel, arranged in a grid connector pins 5, which from the connection side through holes 15 of a filter element 6 (Fig.2) and a section 7 of the screen housing 4 enter the chamber 2 and through the floor 8 of the chamber are guided to the plug side (front) of the filter connector, where they form free plug ends 5a for connection to a plug socket. The free plug ends 5a are surrounded by a collar 9 molded onto the strip body 1, which on its outside has latching elements 10 for latching on a mounting plate 11, for example a front plate of a device. On the connection side (rear), the connector pins 5 are bent approximately at right angles with their sections 5b and soldered to a circuit board 12 (FIG. 3).

Die in der Kammer 2 aufgenommene Ferritkernanordnung 3 weist im Raster der Steckerstifte Bohrungen auf, mit denen der Ferritkern auf die Steckerstifte 5 aufgesteckt ist. Für den Fall, daß nur ein Teil der Steckerstifte, z.B. zwei Steckerstifte oder eine Reihe oder Gruppe von sechs Steckerstiften eines 30-poligen Filter-Steckverbinders mit Filterelementen versehen werden soll bzw. sollen, kann die Ferritkernanordnung z.B. aus einem 2-Lochferritkern oder einem 6-Lochferritkern bestehen und dann nur auf zwei Steckerstifte oder eine Reihe oder Gruppe von sechs Steckerstiften aufgesteckt werden. Die spielfreie Halterung der Ferritkernanordnung 3 in der Kammer 2 des Leistenkörpers 1 wird später noch im Zusammenhang mit dem Schirmgehäuse erläutert.The ferrite core arrangement 3 accommodated in the chamber 2 has holes in the grid of the connector pins with which the ferrite core is plugged onto the connector pins 5. In the event that only a part of the connector pins, e.g. two connector pins or a row or group of six connector pins of a 30-pin filter connector should or should be provided with filter elements, the ferrite core arrangement can consist, for example, of a 2-hole ferrite core or a 6 - Hole ferrite core exist and then only be plugged onto two connector pins or a row or group of six connector pins. The play-free mounting of the ferrite core arrangement 3 in the chamber 2 of the strip body 1 will be explained later in connection with the shield housing.

Das Filterelement 6 (Fig.2) ist auf einem Leiterplatten-Trägermaterial ausgebildet, auf der Anschlußseite (Rückseite) des Schirmgehäuses 4 angeordnet und mit zwei einander gegenüberliegenden Reihen mit einer unterschiedlichen Anzahl von Löchern 13 zur Massekontaktierung und zwischen diesen beiden Reihen mit in SMD-Technik aufgebrachten Kondensatoren 14 sowie mit Löchern 15 für die Steckerstifte 5 versehen.The filter element 6 (FIG. 2) is formed on a printed circuit board carrier material, arranged on the connection side (rear side) of the shield housing 4 and with two mutually opposite rows with a different number of holes 13 for ground contact and between these two rows with SMD Technology applied capacitors 14 and provided with holes 15 for the connector pins 5.

Das Schirmgehäuse (Fig.9 bis 13) besteht aus einem gebrauchs- und steckfertig gebogenen Blechbiegeteil, welches die Seitenwände 16 und zumindest einen Teil der Anschlußseite (Rückseite) des Leistenkörpers 1 und der Kammer 2 unter Aussparung der Steckerstifte 5 abdeckt. Das aus der Abwicklung 4a des Blechbiegeteiles (Fig.13) zu einer rechteckförmigen, an den Eckkanten nicht verbundenen Wanne gebogene Schirmgehäuse 4 weist federnde Seitenteile 17a bis 17d auf, die über die Seitenwände 16 des Leistenkörpers 1 greifen, mit Abwinkelungen ausgebildet sind und an Vorsprüngen 19 der Steckseite (Vorderseite) des Leistenkörpers verrasten. Die Abwinkelungen der federnden Seitenteile 17a bis 17d des Schirmgehäuses 4 sind als einzelne, voneinander beabstandete und zueinander parallele Federarme 18a, 18b ausgebildet, die an einander gegenüberliegenden Seitenteilen 17a und 17b bzw. 17c und 17d jeweils in gleicher Anzahl und zueinander fluchtend angeordnet sind. So weisen die Seitenteile 17a und 17b an der Längsseite des Schirmgehäuses 4 jeweils sieben Federarme 18a, 18b auf, während die Seitenteile 17c und 17d an der Schmalseite des Schirmgehäuses 4 mit jeweils drei Federarmen 18a,18b, ausgebildet sind. Alle Federarme sind vom Rand der Seitenteile 17a bis 17d nach innen gebogen, wobei die nebeneinander liegenden Federarme eines jeden Seitenteiles abwechseind Kontaktelemente 18b zur Ankontaktierung des Schirmgehäuses 4 an einer Montageplatte 11 bzw. Gleit-und Rastelemente 18a zur Verbindung des Schirmgehäuses 4 mit dem Leistenkörper 1 bilden. An den Seitenteilen 17a und 17b des Schirmgehäuses 4 sind in der dargestellten Weise jeweils vier Kontaktelemente 18b und drei Gleit- und Rastelemente 18a vorgesehen, während die Seitenteile 17c und 17d an der Schmalseite des Schirmgehäuses 4 in der dargestellten Weise jeweils mit zwei Kontaktelementen 18b und einem dazwischen angeordneten Gleit- und Rastelement 18a ausgebildet ist. Die Kontaktelemente 18b haben eine V-förmige Grundrißform mit abgerundeter Spitze (Fig.13) und sind schräg zur Steckrichtung nach innen gebogen (Fig.10-12). Die Gleit- und Rastelemente 18a sind rechtwinklig von den Seitenteilen 17a bis 17d nach innen gebogen und mit einem Rastorgan in Form eines an der Abbiegung beginnenden Rastloches 21 versehen, welches zur Verrastung des Schirmgehäuses 4 an einzelnen Vorsprüngen 19 des Leistenkörpers 1 dient. Außerdem sind die Gleit-und Rastelemente 18a an ihrem freien Ende unter Bildung eines Radius 20 quer zur Steckrichtung unter einem Winkel von etwas weniger als 180° zurückgebogen (Fig.11,12).The shield housing (Fig. 9 to 13) consists of a bent sheet metal part ready for use and ready to plug in, which covers the side walls 16 and at least part of the connection side (rear) of the strip body 1 and the chamber 2, with the plug pins 5 being recessed. The shield housing 4, which is bent from the unwinding 4a of the bent sheet metal part (FIG. 13) to form a rectangular trough which is not connected at the corner edges, has resilient side parts 17a to 17d which engage over the side walls 16 of the strip body 1, are formed with bends and on projections 19 engage the plug-in side (front) of the last body. The bends of the resilient side parts 17a to 17d of the screen housing 4 are designed as individual, spaced-apart and mutually parallel spring arms 18a, 18b, which are arranged on opposite side parts 17a and 17b or 17c and 17d in equal numbers and in alignment with one another. Thus, the side parts 17a and 17b on the long side of the shield housing 4 each have seven spring arms 18a, 18b, while the side parts 17c and 17d on the narrow side of the shield housing 4 are each formed with three spring arms 18a, 18b. All spring arms are bent inwards from the edge of the side parts 17a to 17d, the spring arms lying next to each other alternatingly being contact elements 18b for contacting form the shield housing 4 on a mounting plate 11 or slide and locking elements 18a for connecting the shield housing 4 to the strip body 1. On the side parts 17a and 17b of the shield housing 4, four contact elements 18b and three sliding and locking elements 18a are provided in the manner shown, while the side parts 17c and 17d on the narrow side of the shield housing 4 each have two contact elements 18b and one in the manner shown intermediate sliding and locking element 18a is formed. The contact elements 18b have a V-shaped outline shape with a rounded tip (Fig. 13) and are bent inwards at an angle to the direction of insertion (Fig. 10-12). The sliding and latching elements 18a are bent inwards at right angles from the side parts 17a to 17d and provided with a latching element in the form of a latching hole 21 which begins at the bend and which serves for latching the screen housing 4 on individual projections 19 of the strip body 1. In addition, the sliding and locking elements 18a are bent back at their free end to form a radius 20 transversely to the direction of insertion at an angle of somewhat less than 180 ° (FIGS. 11, 12).

Die Seitenwände 16 des Leistenkörpers 1 sind zumindest über einen sich in Steckrichtung erstreckenden Teilbereich zur offenen Anschlußseite (Rückseite) der Kammer 2 hin derart verjüngt, daß Auflauf- und Gleitschrägen 22 für die Gleit- und Rastelemente 18a zwecks Aufweitung der federnden Seitenteile 17a bis 17d des Schirmgehäuses gebildet sind. Hier sind die Seitenwände 16 des Leistenkörpers 1 in Anpassung an die Ausbildung des Schirmgehäuses 4 fürjedes Gleit- und Rastelement 18a jeweils mit einer eigenen Auflauf-und Gleitschräge 22 versehen, wobei diese Auflauf- und Gleitschrägen voneinander entsprechend dem gegenseitigen Abstand der Gleit- und Rastelemente 18a beabstandet sind.The side walls 16 of the strip body 1 are tapered at least over a portion extending in the direction of insertion towards the open connection side (rear) of the chamber 2 in such a way that run-up and sliding bevels 22 for the sliding and latching elements 18a for the purpose of widening the resilient side parts 17a to 17d of the Screen housing are formed. Here, the side walls 16 of the strip body 1 are adapted to the design of the screen housing 4 for each sliding and latching element 18a each with its own ramp and sliding slope 22, these ramp and sliding slopes from each other according to the mutual distance of the sliding and latching elements 18a are spaced.

Die Seitenwände 16 des Leistenkörpers 1 sind hier - jeweils in Steckrichtung gesehen - über etwa zwei Drittel ihrer Erstreckung mit den Auflauf- und Gleitschrägen 22 und über etwa ein Drittel ihrer Ersteckung mit zur Steckrichtung parallelen Geradflächen 23 ausgebildet, wobei diese Geradflächen bis zu den Kanten 24 an der Steckseite (Vorderseite) des Leistenkörpers 1 reichen.The side walls 16 of the strip body 1 are here - in each case seen in the direction of insertion - formed over approximately two thirds of their extent with the run-up and sliding bevels 22 and over approximately one third of their extent with straight surfaces 23 parallel to the direction of insertion, these straight surfaces up to the edges 24 on the plug-in side (front) of the last body 1.

Außerdem sind die Seitenwände 16 des Leistenkörpers 1 noch - wie besonders deutlich die Fig. 5 und 6 zeigen - mit Vertiefungen 34 ausgebildet, welche für die Kontaktelemente 18b vorgesehen und deren Form angepaßt sind. Diese Vertiefungen erstrecken sich hier an den Schmalseiten 35 (Fig.6) über die ganze Höhe der Seitenwände 16 des Leistenkörpers und an dessen Längsseiten 36 nur in einem kurzen, dem Kragen 9 (Fig.8) benachbarten Abschnitt der Seitenwände 16.In addition, the side walls 16 of the strip body 1 are - as particularly clearly shown in FIGS. 5 and 6 - formed with recesses 34 which are provided for the contact elements 18b and the shape of which is adapted. These depressions here extend on the narrow sides 35 (FIG. 6) over the entire height of the side walls 16 of the last body and on its longitudinal sides 36 only in a short section of the side walls 16 adjacent to the collar 9 (FIG. 8).

Ferner ist das Schirmgehäuse 4 auch in einer zur Durchführung der Steckerstifte 5 sowie zur Halterung des Filterelementes 6 und der Ferritkernanordnung 3 vorteilhaften Weise ausgebildet. Die die offene Kammer 2 des Leistenkörpers 1 abdeckende Bodenfläche 25 des Schirmgehäuses 4 ist hierzu mit einem zentrisch angeordneten rechteckförmigen Ausschnitt 7 versehen, der an zwei einander gegenüberliegenden Längsseiten zueinander parallele Stege 27 und Spieße 28 aufweist, die in der Abwicklung (Fig.13) des Schirmgehäuses zunächst in einer Ebene liegend und aufeinander gerichtet sind. Die keilförmig verjüngten Stege 27 sind zur Halterung der Ferritkernanordnung 3 - wie in Fig.9 zu sehen ist - schräg zur Bodenfläche 25 verlaufend nach innen gebogen, so daß sie die Ferritkernanordnung federnd gegen den Boden 8 der Kammer 2 drücken. Die im Vergleich zu den Stegen etwas kürzeren Spieße 28 zum Aufstecken des Filterelementes 6 dagegen sind senkrecht zur Bodenfläche 25 nach außen gebogen. Die einander diagonal gegenüberliegenden Außenspieße 28a und 28b sind im Vergleich zu den übrigen Spießen 28 etwas länger und werden nach dem Aufstecken des Filterelementes 6 zu dessen Vorfixierung bis zum Lötvorgang umgelegt. Schließlich sind aus der die offene Kammer 2 des Leistenkörpers 1 abdeckenden Bodenfläche 25 des Schirmgehäuses 4 symmetrisch in bezug auf die Mitte der Bodenfläche angeordnete Federarme 29 herausgerissen und schräg zur Bodenfläche 25 nach innen gebogen, wobei in den Fig.9 und 13 zu sehen ist , daß diese Federarme 29 in Längsrichtung im wesentlichen parallel zu den Seitenteilen 17c und 17d des Schirmgehäuses 4 verlaufen. Die Federarme 29 dienen zur selbsttätigen Verrastung des Schirmgehäuses 4 am Leistenkörper 1.Furthermore, the shield housing 4 is also designed in a manner which is advantageous for carrying out the plug pins 5 and for holding the filter element 6 and the ferrite core arrangement 3. For this purpose, the bottom surface 25 of the umbrella housing 4 covering the open chamber 2 of the strip body 1 is provided with a centrally arranged rectangular cutout 7 which has webs 27 and skewers 28 which are parallel to one another on two opposite longitudinal sides and which are in the development (FIG. 13) of the Umbrella housing are initially lying in one plane and facing each other. The wedge-shaped tapered webs 27 for holding the ferrite core arrangement 3 - as can be seen in FIG. 9 - are bent inwards at an angle to the bottom surface 25, so that they press the ferrite core arrangement resiliently against the bottom 8 of the chamber 2. The skewers 28, which are somewhat shorter than the webs, for fitting the filter element 6, on the other hand, are bent outwards perpendicularly to the bottom surface 25. The diagonally opposite one another Outer skewers 28a and 28b are somewhat longer in comparison to the other skewers 28 and are flipped over after the filter element 6 has been plugged in to fix it in place until the soldering process. Finally, spring arms 29 arranged symmetrically with respect to the center of the bottom surface are torn out of the bottom surface 25 of the shield housing 4 covering the open chamber 2 of the strip body 1 and bent obliquely inwards to the bottom surface 25, with FIGS. 9 and 13 showing that these spring arms 29 extend in the longitudinal direction substantially parallel to the side parts 17c and 17d of the screen housing 4. The spring arms 29 serve for the automatic locking of the shield housing 4 on the strip body 1.

Aus Gründen der Vollständigkeit wird ergänzt, daß das Seitenteil 17a des Schirmgehäuses 4 zwei kreisrunde Löcher 30 für Befestigungsniete 31 zur Befestigung des Filter-Steckverbinders an der Schaltungsplatte 12 aufweist und in den Biegekanten 26 der Seitenteile 17a bis 17d schmale Längsschlitze 32 und seitlich der Federarme 18a, 18b in den Seitenteilen 17a bis 17d kleine Freischnitte 33 als Biegehilfen vorgesehen sind.For the sake of completeness, it is added that the side part 17a of the shield housing 4 has two circular holes 30 for fastening rivets 31 for fastening the filter connector to the circuit board 12 and in the bending edges 26 of the side parts 17a to 17d narrow longitudinal slots 32 and to the side of the spring arms 18a , 18b in the side parts 17a to 17d small free cuts 33 are provided as bending aids.

Bei der Montage des Steckverbinders wird zunächst das Filterelement 6 auf dem Schirmgehäuse 4 vormontiert, d.h. auf die hochstehenden Spieße 28 und 28a,b aufgesteckt, wobei die längeren, diagonal gegenüberliegenden Außenspieße 28a und 28b umgelegt werden und das Filterelement 6 dadurch vorfixiert wird. Das Filterelement wird also in einfacher Weise von der Anschlußseite (Rückseite) her dem Schirmgehäuse zugeführt. Darauf wird die Ferritkernanordnung 3 über die Steckstifte 5 gesteckt (aufgefädelt). Anschließend wird das Schirmgehäuse 4 auf den Leistenkörper 1 geschoben oder dieser in das Schirmgehäuse gesteckt, welches in der beschriebenen Weise selbsttätig aufgrund der in der Bodenfläche 25 des Schirmgehäuses 4 angeordneten Federarme 29 am Leistenkörper verrastet. Danach erfolgt der Tauch-Löt-Vorgang, bei dem in einem Arbeitsgang die Steckerstifte 5 in den Löchern 15 des Filterelementes 6 verlötet werden und die Masseverbindungen zwischen den Spießen 28, 28a, 28b und den zugehörigen Löchern 13 erfolgt. Nach dem Verlöten werden die steckerstifte 5 rechtwinklig abgebogen. Diese Montageabfolge läßt sich in besonders kostengünstiger Weise durchführen.When assembling the connector, the filter element 6 is first preassembled on the shield housing 4, that is to say plugged onto the upstanding spikes 28 and 28a, b, the longer, diagonally opposite outer spikes 28a and 28b being flipped over and the filter element 6 thereby being pre-fixed. The filter element is therefore fed to the shield housing in a simple manner from the connection side (rear). The ferrite core arrangement 3 is then plugged (threaded) over the plug pins 5. Then the shield housing 4 is pushed onto the strip body 1 or this is inserted into the shield housing, which automatically locks in the manner described on the ledge body due to the spring arms 29 arranged in the bottom surface 25 of the screen housing 4. This is followed by the dip-soldering process, in which the plug pins 5 are soldered in the holes 15 of the filter element 6 in one operation and the ground connections between the spikes 28, 28a, 28b and the associated holes 13 take place. After soldering, the pins 5 are bent at right angles. This assembly sequence can be carried out in a particularly cost-effective manner.
