Definitions

  • the present invention relates to a connector housing which can be fastened in a rectangular plate opening and consists of an approximately parallelepipedic block of insulating material with at least one recess running through from a front to a rear end face for receiving an electrical connector and of elastically flexible holding fingers which start from side faces of the block of insulating material and are angled into a position approximately parallel to these side surfaces and each have an inclined surface rising from the free end of the holding finger and a descending step, the holding fingers running approximately parallel to one another, but are in opposite directions, so that the steps of oppositely directed holding fingers are in contact are suitable at front and rear edge edges of the plate opening and is based on US Pat. No. 3,989,343.
  • a connector housing of the type mentioned offers the advantage that it can be inserted either with the front or the rear end face of the insulating material block in front into a rectangular plate opening and can be fastened to the plate by latching the falling steps of the retaining fingers.
  • the connector housing can also be removed from the plate either in one direction or in the opposite direction.
  • US-A-3989343 describes a connector, the latching members of which are arranged on only two opposite sides in such a way that one latching member counteracts the other latching members in such a way that fastening in a rectangular plate opening is also ensured.
  • the locking elements that act in one direction do not differ in shape from those that act in the other direction.
  • the arrangement is selected such that two latching members act in one direction on each side and, in contrast, a single latching member in the other direction.
  • a property of this arrangement is that only two preferred sides of the plug can be selected for releasing the latching elements for removing the plug.
  • US-A-2 891 103 describes a connector with two different types of latching members, which are opposite each other in pairs on two sides. This means that there are latching members of one type on two opposite sides and latching members of another type on the other opposite sides. The interaction of these different types of locking elements results in holding in a rectangular plate opening. In the arrangement shown or disclosed, the plug connector can only be inserted into the plate opening from one side. Furthermore, the resilient locking members are not holding fingers.
  • the CH-A-463 592 shows no locking hooks, but at least slightly resilient pressing elements. It would be difficult to release a plug housing once it has been snapped into place.
  • connector housings of this type In a further known embodiment of connector housings of this type according to DE-C-1964681, three holding fingers are arranged exclusively on two mutually opposite side surfaces of the insulating material block, a middle holding finger pointing against one end surface and two outer fingers against the other end surface of the insulating material block . Therefore, the descending steps on a total of two holding fingers serve to absorb forces in one direction and the steps on a total of four holding fingers serve to absorb forces in the opposite direction. In addition, the steps on the middle holding fingers are less able to secure the connector housing against tilting in the panel opening than the steps on the outer holding fingers.
  • the object of the present invention is to design a connector housing of the type mentioned at the outset in such a way that increased stability of the connector housing in the panel opening is ensured, even if the panel opening is not closely matched to the cross section of the insulating material block.
  • an incoming connection should be easily releasable if necessary.
  • This design ensures a particularly stable fit of the connector housing in the panel opening without impairing the releasability.
  • the connector housing 10 illustrated in FIGS. 1 to 3 has a substantially parallelepiped insulating material block 11 with a front end surface 12, a rear end surface 13 and four side surfaces 14, 15, 16 and 17.

  • the insulating material block 11 is provided with a plurality of elastically flexible holding fingers 22 and 23, which expediently consist of a single piece of material together with the insulating material block 11.
  • Two of these holding fingers 22 and 23 are arranged on each of the four side surfaces 14 to 17 of the insulating material block 11.
  • the holding fingers 22 and 23 each extend from the relevant side surface 14, 15, 16 and 17 of the insulating material block 11 and are angled into a position approximately parallel to the relevant side surface. Furthermore, all of the holding fingers 22 and 23 are approximately parallel to one another, but some of them point in the opposite direction, as can be clearly seen in FIGS. 1 and 2.
  • the first-mentioned holding fingers 22 each have an inclined surface 24 rising from their free end and a falling step 25.
  • an inclined surface 26 rising from the free end and a falling step 27 are formed on the other holding fingers 23. Steps 25 and 27 are intended to rest against rear and front edge edges of plate opening 20, as can be seen in FIGS. 1 to 3.
  • the inclined surfaces 24 of the one holding finger 22 allow the connector housing 10 to be inserted comfortably into the plate opening 20 with the rear end surface 13 ahead, the inclined surfaces 24 sliding on edge edges of the plate opening 20 and thus elastically pushing the holding fingers 22 against the insulating material block 11 until snap the steps 25 of these retaining fingers onto the back of the plate 21.
  • the inclined surfaces 26 of the other holding fingers 23 allow the connector housing 10 to be inserted into the plate opening 20 with the front end surface 12 in front just as easily until the steps 27 of the holding fingers 23 engage on the front side of the plate 21. In the installed state of the connector housing 10, the latter is by the steps 25 and 27 of all holding fingers 22 and 23 against movements forwards and backwards, ie.

  • These surfaces 31 and 32 are guide surfaces which are intended to cooperate with the boundary surfaces of the plate opening 20 in the corner parts thereof when the connector housing 10 is inserted into the plate opening 20. This avoids that the connector housing can be tilted due to the elastic flexibility of the retaining fingers 22 and 23 in the plate opening 20.
  • the second exemplary embodiment of the connector housing 10 according to the invention differs from the first example described above only in that instead of each of the opposite side surfaces 14 and 16, of which the latter is not visible in FIG. 4 the two holding fingers 22 there is only a single holding finger 122 with a larger width.
  • This wider holding finger 122 has an inclined surface 124 rising from the free end and a descending step 125, this inclined surface 124 and the step 125 extending over the entire width of the holding finger 122 and having the same functions as the inclined surface 24 and the step 25 of each holding finger 22 of the first embodiment.
  • two holding fingers 22 and 223 pointing in the same direction are arranged on each side surface of the insulating material block 11.
  • the differences from the first exemplary embodiment according to FIGS. 1 to 3 are as follows:
  • the two holding fingers 22 which are arranged on each of the mutually opposite side surfaces 14 and 16 of the insulating material block 11 and which point in the direction from the front end surface 12 to the rear end surface 13 a greater distance from each other than in the first embodiment.
  • a cam 230 protruding from the insulating material block 11.
  • the apex of the convexly curved end face 231 of the cam 230 is in contact a boundary surface of the plate opening in which the connector housing can be inserted.
  • the two holding fingers 223 arranged on each of the other side surfaces 15 and 17 of the insulating material block 11, which point in the direction from the rear end surface 13 to the front end surface 12 of the insulating material block, are also so far apart from one another that a cam 235 protruding from the insulating material block is located therebetween finds.
  • the apex of the convexly curved end face 236 of this cam is also intended to bear against a boundary surface of the plate opening.
  • flanks 238 are widened beyond the adjacent side surfaces 14 and 16 of the insulating material block 11, so that these flanks 238 are suitable instead of the cams 30 of the first exemplary embodiment for contacting boundary surfaces of the plate opening in the corner parts thereof, un to secure the connector housing built into the panel opening against rotation in the panel opening.
  • the fourth exemplary embodiment of the connector housing 10 according to the invention illustrated in FIG. 6 has structural features of the second and the third exemplary embodiment.
  • Only one holding finger 122 or 323 is provided on each of the four side surfaces 14 to 17 of the insulating material block 11.
  • the holding fingers 122 arranged on the side surfaces 14 and 16 each have a width which corresponds approximately to the width of the insulating material block 11 measured in the same direction.
  • the holding fingers 323 arranged on the other side surfaces 15 and 17, on the other hand, are each widened beyond the adjacent side surfaces 14 and 16, so that the flanks 338 of these holding fingers 323 are suitable for abutment on boundary surfaces of the plate opening in corner parts thereof, like the end surfaces 31 of the cams 30 of the first embodiment.
  • the holding fingers 122 and 323 each have an inclined surface 124 or 326 rising from the free end and a falling step 125 or 327, these inclined surfaces and steps each extending over the entire width of the holding finger in question.
  • the holding fingers 22, 23 or 122, 23 or 22, 223 or 122, 323 arranged on all four side surfaces 14 to 17 of the insulating material block 11 have the connector housing 10 inserted into a panel opening 20 give greater stability than is the case with known connector housings, in which similar holding fingers are only present on two opposite side faces of the insulating material block and engage in one another like fingers.
  • the steps 25 and 27 or 125 and 27 or 125 and 327 ensuring the hold in the plate opening 20 have larger areas overall, which cooperate with edge parts of the plate opening 20.

  • the described arrangement and design of the holding fingers of the connector housing according to the invention also makes it possible to make the dimensions of the plate opening 20 somewhat larger than before, because the holding fingers are able to give the connector housing a sufficiently good stability in the plate opening, even if the cams 30, 230 or 235 or the flanks 238 or 338 of the holding fingers 223 or 323 do not bear directly against the boundary surfaces of the plate opening. Thus, larger tolerances than previously are permitted for the dimensions of the plate opening.

  • the hook-shaped locking member 340 itself is rigid, but is connected in its central part by means of an elastically flexible web 345 to the relevant side surface 15 or 17 of the insulating material block 11. This enables the head 346 of the locking member 340, which is designed as a hook, to snap into the bow-shaped extension 344 automatically, and by pressing the end part 347 facing away from the head 346, the locking member 340 can be pivoted such that its head 346 disengages from the extension 344 and then the connector housings 10 and 341 can be separated.

Description

Die vorliegende Erfindung betrifft ein in einer rechteckigen Plattenöffnung befestigbares Steckverbinder-Gehäuse, bestehend aus einem etwa parallelepipedischen Isoliermaterialblock mit wenigstens einer von einer vorderen zu einer hinteren Endfläche durchgehenden Ausnehmung zur Aufnahme eines elektrischen Steckverbinders und aus elastisch biegsamen Haltefingern, die von Seitenflächen des Isoliermaterialblockes ausgehen und in eine zu diesen Seitenflächen annähernd parallele Lage abgewinkelt sind und aussen je eine vom freien Ende des Haltefingers ansteigende Schrägfläche und eine abfallende Stufe aufweisen, wobei die Haltefinger etwa parallel zueinander verlaufen, aber teils entgegengesetzt gerichtet sind, so dass die Stufen entgegengesetzt gerichteter Haltefinger zum Anliegen an vordere bzw. hintere Randkanten der Plattenöffnung geeignet sind und geht aus von der US-A-3 989 343.The present invention relates to a connector housing which can be fastened in a rectangular plate opening and consists of an approximately parallelepipedic block of insulating material with at least one recess running through from a front to a rear end face for receiving an electrical connector and of elastically flexible holding fingers which start from side faces of the block of insulating material and are angled into a position approximately parallel to these side surfaces and each have an inclined surface rising from the free end of the holding finger and a descending step, the holding fingers running approximately parallel to one another, but are in opposite directions, so that the steps of oppositely directed holding fingers are in contact are suitable at front and rear edge edges of the plate opening and is based on US Pat. No. 3,989,343.

Ein Steckverbinder-Gehäuse der genannten Art bietet den Vorteil, dass es wahlweise mit der vorderen oder der hinteren Endfläche des Isoliermaterialblockes voran in eine rechteckige Plattenöffnung eingeführt und durch Einrasten der abfallenden Stufen der Haltefinger an der Platte befestigt werden kann. Das Abnehmen des Steckverbinder-Gehäuses von der Platte kann ebenfalls wahlweise in der einen oder in der entgegengesetzten Richtung erfolgen.A connector housing of the type mentioned offers the advantage that it can be inserted either with the front or the rear end face of the insulating material block in front into a rectangular plate opening and can be fastened to the plate by latching the falling steps of the retaining fingers. The connector housing can also be removed from the plate either in one direction or in the opposite direction.

Die US-A-3989343 beschreibt einen Steckverbinder, dessen Rastglieder nur auf zwei einander gegenüberliegenden Seiten so angeordnet sind, dass die einen Rastglieder den anderen Rastgliedem so entgegenwirken, dass eine Befestigung in einer rechteckigen Plattenöffnung ebenfalls gewährleistet ist. Die Rastglieder, die in die eine Richtung wirken, unterscheiden sich nicht in ihrer Form von denen, die in die andere Richtung wirken. Die Anordnung ist jedoch so gewählt, dass jeweils pro Seite zwei Rastglieder in die eine Richtung wirken und dagegen ein einzelnes Rastglied in die andere Richtung. Eine Eigenschaft dieser Anordnung ist, dass für das Entfernen des Steckers nur zwei bevorzugte Seiten des Steckers für das Lösen der Rastglieder gewählt werden können.US-A-3989343 describes a connector, the latching members of which are arranged on only two opposite sides in such a way that one latching member counteracts the other latching members in such a way that fastening in a rectangular plate opening is also ensured. The locking elements that act in one direction do not differ in shape from those that act in the other direction. However, the arrangement is selected such that two latching members act in one direction on each side and, in contrast, a single latching member in the other direction. A property of this arrangement is that only two preferred sides of the plug can be selected for releasing the latching elements for removing the plug.

Die US-A-2 891 103 beschreibt einen Steckverbinder mit zwei verschiedenartigen Rastglieder, die je zu Paaren an zwei Seiten gegenüberliegen. Das heisst, es liegen auf zwei sich gegenüberliegenden Seiten Rastglieder des einen Typs und auf den anderen gegenüberliegenden Seiten Rastglieder eines anderen Typs. Das Zusammenwirken dieser verschiedenartigen Rastglieder bewirken das Halten in einer rechteckigen Plattenöffnung. Bei der gezeigten bzw. offenbarten Anordnung kann der Steckverbinder nur von einer Seite in die Plattenöffnung eingeschoben werden Ferner sind die federnden Rastglieder keine Haltefinger.US-A-2 891 103 describes a connector with two different types of latching members, which are opposite each other in pairs on two sides. This means that there are latching members of one type on two opposite sides and latching members of another type on the other opposite sides. The interaction of these different types of locking elements results in holding in a rectangular plate opening. In the arrangement shown or disclosed, the plug connector can only be inserted into the plate opening from one side. Furthermore, the resilient locking members are not holding fingers.

Die CH-A-463 592 zeigt keine Rasthaken, sondem zumindest leicht federnde Anpresselemente. Ein Lösen eines einmal eingerasteten Steckergehäuses wäre nur mit Schwierigkeiten möglich.The CH-A-463 592 shows no locking hooks, but at least slightly resilient pressing elements. It would be difficult to release a plug housing once it has been snapped into place.

Bei einer weiteren bekannten Ausführungsformen von Steckverbinder-Gehäusen dieser Art gemäss DE-C-1964681 sind jeweils drei Haltefinger ausschliesslich an zwei einander gegenüberliegenden Seitenflächen des Isoliermaterialblockes angeordnet, wobei ein mittlerer Haltefinger gegen die eine Endfläche und zwei äussere Finger gegen die andere Endfläche des Isoliermaterialblockes weisen. Deshalb dienen die abfallenden Stufen an insgesamt zwei Haltefingern zur Aufnahme von Kräften in der einen Richtung und die Stufen an insgesamt vier Haltefingern zur Aufnahme von Kräften in der entgegengesetzten Richtung. Zudem vermögen die Stufen an den mittleren Haltefingern das Steckverbinder-Gehäuse weniger gut gegen Verkanten in der Plattenöffnung zu sichern als die Stufen an den äusseren Haltefingern. Um dennoch einen ausreichend stabilen Sitz des Steckverbinder-Gehäuses in der Plattenöffnung zu erzielen, ist es notwendig, die Plattenöffnung verhältnismässig eng an den Isoliermaterialblock anzupassen, so dass die nicht mit Haltefingern versehenen Seitenflächen des Isoliermaterialblockes an den benachbarten Randkanten der Plattenöffnung einen Halt finden.In a further known embodiment of connector housings of this type according to DE-C-1964681, three holding fingers are arranged exclusively on two mutually opposite side surfaces of the insulating material block, a middle holding finger pointing against one end surface and two outer fingers against the other end surface of the insulating material block . Therefore, the descending steps on a total of two holding fingers serve to absorb forces in one direction and the steps on a total of four holding fingers serve to absorb forces in the opposite direction. In addition, the steps on the middle holding fingers are less able to secure the connector housing against tilting in the panel opening than the steps on the outer holding fingers. In order to achieve a sufficiently stable fit of the connector housing in the panel opening, it is necessary to adapt the panel opening relatively closely to the insulating material block, so that the side surfaces of the insulating material block which are not provided with retaining fingers find a hold on the adjacent edge edges of the panel opening.

Aufgabe der vorliegenden Erfindung ist es, ein Steckverbinder-Gehäuse der eingangs genannten Art so auszugestalten, dass eine erhöhte Stabilität des Steckverbinder-Gehäuses in der Plattenöffnung gewährleistet ist, und zwar selbst dann, wenn keine enge Anpassung der Plattenöffnung an den Querschnitt des Isoliermaterialblockes vorliegt. Zudem soll eine eingegangene Verbindung gegebenenfalls wieder einfach lösbar sein.The object of the present invention is to design a connector housing of the type mentioned at the outset in such a way that increased stability of the connector housing in the panel opening is ensured, even if the panel opening is not closely matched to the cross section of the insulating material block. In addition, an incoming connection should be easily releasable if necessary.

Diese Aufgabe ist erfindungsgemäss durch eine Konstruktion gemäss dem kennzeichnenden Teil von Anspruch 1 gelöst.This object is achieved according to the invention by a construction according to the characterizing part of claim 1.

Durch diese Ausbildung ist ein besonders stabiler Sitz des Steckverbinder-Gehäuses in der Plattenöffnung gewährleistet, ohne die Lösbarkeit zu beeinträchtigen.This design ensures a particularly stable fit of the connector housing in the panel opening without impairing the releasability.

Das in den Fig. 1 bis 3 veranschaulichte Steckverbinder-Gehäuse 10 weist einen im wesentlichen parallelepipedischen Isoliermaterialblock 11 mit einer vorderen Endfläche 12, einer hinteren Endfläche 13 und vier Seitenflächen 14, 15, 16 und 17 auf. Der Isoliermaterialblock 11 ist mit mehreren von der vorderen zur hinteren Endfläche 12 bzw. 13 durchgehenden Ausnehmungen 18 zur Aufnahme von (nicht gezeigten) elektrischen Steckverbindern versehen, die wahlweise Stecker oder Steckbuchsen sein können.The connector housing 10 illustrated in FIGS. 1 to 3 has a substantially parallelepiped insulating material block 11 with a front end surface 12, a rear end surface 13 and four side surfaces 14, 15, 16 and 17. The insulating material block 11 is provided with a plurality of recesses 18, which extend from the front to the rear end surface 12 or 13, for receiving electrical connectors (not shown), which can optionally be plugs or sockets.

Zum Befestigen des Steckverbinder-Gehäuses 10 in einer rechteckigen Oeffnung 20 einer Platte 21 ist der Isoliermaterialblock 11 mit mehreren elastisch biegsamen Haltefingern 22 und 23 versehen, die zweckmässig zusammen mit dem Isoliermaterialblock 11 aus einem einzigen Materialstück bestehen. An jeder der vier Seitenflächen 14 bis 17 des Isoliermaterialblockes 11 sind zwei dieser Haltefinger 22 bzw. 23 angeordnet. Die Haltefinger 22 und 23 gehen je von der betreffenden Seitenfläche 14, 15, 16 bzw. 17 des lsoliermaterialblockes 11 aus und sind in eine zu der betreffenden Seitenfläche annähernd parallele Lage abgewinkelt. Ferner sind sämtliche Haltefinger 22 und 23 zueinander etwa parallel, aber sie weisen teils in entgegengesetzte Richtung, wie in den Fig. 1 und 2 deutlich erkennbar ist. Die einen Haltefinger 22, welche an den einander gegenüberliegenden Seitenflächen 14 und 16 angeordnet sind, verlaufen von der vorderen Endfläche 12 des Isoliermaterialblockes 11 in Richtung gegen die hintere Endfläche 13, wogegen die andern Haltefinger 23, die an den einander ebenfalls gegenüberliegenden Seitenflächen 15 und 17 angeordnet sind, in Richtung von der hinteren zur vorderen Endfläche des Isoliermaterialblockes 11 verlaufen. Die erstgenannten Haltefinger 22 weisen je eine von ihrem freien Ende ansteigende Schrägfläche 24 und eine abfallende Stufe 25 auf. In analoger Weise sind an den andern Haltefingern 23 je eine von dem freien Ende ansteigende Schrägfläche 26 und eine abfallende Stufe 27 ausgebildet. Die Stufen 25 und 27 sind zum Anliegen an hintere bzw. vordere Randkanten der Plattenöffnung 20 bestimmt, wie die Fig. 1 bis 3 erkennen lassen. Die Schrägflächen 24 der einen Haltefinger 22 erlauben ein bequemes Einführen des Steckverbinder-Gehäuses 10 in die Plattenöffnung 20 mit der hinteren Endfläche 13 voran, wobei die Schrägflächen 24 an Randkanten der Plattenöffnung 20 gleiten und somit die Haltefinger 22 elastisch gegen den Isoliermaterialblock 11 drängen, bis die Stufen 25 dieser Haltefinger auf der Rückseite der Platte 21 einrasten. In analoger Weise gestatten die Schrägflächen 26 der anderen Haltefinger 23 ein ebenso bequemes Einführen des Steckverbinder-Gehäuses 10 in die Plattenöffnung 20 mit der vorderen Endfläche 12 voran, bis die Stufen 27 der Haltefinger 23 auf der Vorderseite der Platte 21 einrasten. Im eingebauten Zustand des Steckverbinder-Gehäuses 10 ist letzteres durch die Stufen 25 und 27 aller Haltefinger 22 und 23 gegen Bewegungen nach vorn und hinten, d. h. in beiden Richtungen der Ausnehmungen 18, gesichert.To fasten the connector housing 10 in a rectangular opening 20 of a plate 21, the insulating material block 11 is provided with a plurality of elastically flexible holding fingers 22 and 23, which expediently consist of a single piece of material together with the insulating material block 11. Two of these holding fingers 22 and 23 are arranged on each of the four side surfaces 14 to 17 of the insulating material block 11. The holding fingers 22 and 23 each extend from the relevant side surface 14, 15, 16 and 17 of the insulating material block 11 and are angled into a position approximately parallel to the relevant side surface. Furthermore, all of the holding fingers 22 and 23 are approximately parallel to one another, but some of them point in the opposite direction, as can be clearly seen in FIGS. 1 and 2. The one holding finger 22, which is arranged on the mutually opposite side surfaces 14 and 16, extends from the front end surface 12 of the insulating material block 11 in the direction toward the rear end surface 13, whereas the other holding fingers 23, which on the likewise opposite side surfaces 15 and 17 are arranged, extend in the direction from the rear to the front end surface of the insulating material block 11. The first-mentioned holding fingers 22 each have an inclined surface 24 rising from their free end and a falling step 25. In an analogous manner, an inclined surface 26 rising from the free end and a falling step 27 are formed on the other holding fingers 23. Steps 25 and 27 are intended to rest against rear and front edge edges of plate opening 20, as can be seen in FIGS. 1 to 3. The inclined surfaces 24 of the one holding finger 22 allow the connector housing 10 to be inserted comfortably into the plate opening 20 with the rear end surface 13 ahead, the inclined surfaces 24 sliding on edge edges of the plate opening 20 and thus elastically pushing the holding fingers 22 against the insulating material block 11 until snap the steps 25 of these retaining fingers onto the back of the plate 21. In an analogous manner, the inclined surfaces 26 of the other holding fingers 23 allow the connector housing 10 to be inserted into the plate opening 20 with the front end surface 12 in front just as easily until the steps 27 of the holding fingers 23 engage on the front side of the plate 21. In the installed state of the connector housing 10, the latter is by the steps 25 and 27 of all holding fingers 22 and 23 against movements forwards and backwards, ie. H. secured in both directions of the recesses 18.

An den vier von der vorderen Endfläche 12 zur hinteren Endfläche 13 verlaufenden Kanten des Isoliermaterialblockes 11 ist je ein vom Isoliermaterialblock abstehender starrer Nocken 30 vorhanden, der eine konvex gewölbte Stirnfläche 31 und eine ebene Aussenseitenfläche 32 aufweist. Diese Flächen 31 und 32 sind Führungsflächen, die zum Zusammenarbeiten mit den Begrenzungsflächen der Plattenöffnung 20 in deren Eckpartien bestimmt sind, wenn das Steckverbinder-Gehäuse 10 in die Plattenöffnung 20 eingesetzt ist. Hierdurch wird vermieden, dass das Steckverbinder-Gehäuse infolge der elastischen Nachgiebigkeit der Haltefinger 22 und 23 in der Plattenöffnung 20 schräggestellt werden kann.On the four edges of the insulating material block 11 running from the front end surface 12 to the rear end surface 13 there is a rigid cam 30 projecting from the insulating material block, which has a convexly curved end surface 31 and a flat outer surface 32. These surfaces 31 and 32 are guide surfaces which are intended to cooperate with the boundary surfaces of the plate opening 20 in the corner parts thereof when the connector housing 10 is inserted into the plate opening 20. This avoids that the connector housing can be tilted due to the elastic flexibility of the retaining fingers 22 and 23 in the plate opening 20.

Das in Fig. 4 teilweise dargestellte zweite Ausführungsbeispiel des erfindungsgemässen Steckverbinder-Gehäuses 10 unterscheidet sich von dem vorstehend beschriebenen ersten Beispiel lediglich dadurch, dass an den einander gegenüberliegenden Seitenflächen 14 und 16, von denen die letztere in Fig. 4 nicht sichtbar ist, jeweils anstelle der zwei Haltefinger 22 nur ein einziger Haltefinger 122 mit grösserer Breite vorhanden ist. Dieser breitere Haltefinger 122 weist eine von dem freien Ende ansteigende Schrägfläche 124 und eine abfallende Stufe 125 auf, wobei diese Schrägfläche 124 und die Stufe 125 sich über die ganze Breite des Haltefingers 122 erstrecken und die gleichen Funktionen haben wie die Schrägfläche 24 und die Stufe 25 eines jeden Haltefingers 22 des ersten Ausführungsbeispiels.The second exemplary embodiment of the connector housing 10 according to the invention, which is partially shown in FIG. 4, differs from the first example described above only in that instead of each of the opposite side surfaces 14 and 16, of which the latter is not visible in FIG. 4 the two holding fingers 22 there is only a single holding finger 122 with a larger width. This wider holding finger 122 has an inclined surface 124 rising from the free end and a descending step 125, this inclined surface 124 and the step 125 extending over the entire width of the holding finger 122 and having the same functions as the inclined surface 24 and the step 25 of each holding finger 22 of the first embodiment.

Bei der in Fig. 5 gezeigten weiteren Ausführungsform des erfindungsgemässen Steckverbinder-Gehäuses 10 sind an jeder Seitenfläche des Isoliermaterialblockes 11 zwei in der gleichen Richtung weisende Haltefinger 22 bzw. 223 angeordnet. Die Unterschiede gegenüber dem ersten Ausführungsbeispiel gemäss den Fig. 1 bis 3 sind wie folgt : Die an jeder der einander gegenüberliegenden Seitenflächen 14 und 16 des Isoliermaterialblockes 11 angeordneten zwei Haltefinger 22, die in Richtung von der vorderen Endfläche 12 zur hinteren Endfläche 13 weisen, haben voneinander einen grösseren Abstand als beim ersten Ausführungsbeispiel. Im Zwischenraum zwischen diesen beiden Haltefingern 22 befindet sich ein vom Isoliermaterialblock 11 abstehender Nocken 230. Der Scheitel der konvex gewölbten Stirnfläche 231 des Nockens 230 ist zum Anliegen an einer Begrenzungsfläche der Plattenöffnung bestimmt, in weiche das Steckverbinder-Gehäuse einsetzbar ist. Die an jeder der anderen Seitenflächen 15 und 17 des Isoliermaterialblockes 11 angeordneten zwei Haltefinger 223, die in Richtung von der hinteren Endfläche 13 zur vorderen Endfläche 12 des Isoliermaterialblockes weisen, sind ebenfalls so weit voneinander entfernt, dass dazwischen ein von dem Isoliermaterialblock abstehender Nocken 235 Platz findet. Der Scheitel der konvex gewölbten Stirnfläche 236 dieses Nockens ist ebenfalls zum Anliegen an einer Begrenzungsfläche der Plattenöffnung bestimmt. Ferner sind die beiden Haltefinger 223 an ihren voneinander abgewandten Flanken 238 über die benachbarten Seitenflächen 14 und 16 des Isoliermaterialblockes 11 hinaus verbreitert, so dass diese Flanken 238 anstelle der Nocken 30 des ersten Ausführungsbeispiels zum Anliegen an Begrenzungsflächen der Plattenöffnung in deren Eckpartien geeignet sind, un das in die Plattenöffnung eingebaute Steckverbinder-Gehäuse gegen Drehung in der Plattenöffnung zu sichern.In the further embodiment of the connector housing 10 according to the invention shown in FIG. 5, two holding fingers 22 and 223 pointing in the same direction are arranged on each side surface of the insulating material block 11. The differences from the first exemplary embodiment according to FIGS. 1 to 3 are as follows: The two holding fingers 22 which are arranged on each of the mutually opposite side surfaces 14 and 16 of the insulating material block 11 and which point in the direction from the front end surface 12 to the rear end surface 13 a greater distance from each other than in the first embodiment. In the space between these two holding fingers 22 there is a cam 230 protruding from the insulating material block 11. The apex of the convexly curved end face 231 of the cam 230 is in contact a boundary surface of the plate opening in which the connector housing can be inserted. The two holding fingers 223 arranged on each of the other side surfaces 15 and 17 of the insulating material block 11, which point in the direction from the rear end surface 13 to the front end surface 12 of the insulating material block, are also so far apart from one another that a cam 235 protruding from the insulating material block is located therebetween finds. The apex of the convexly curved end face 236 of this cam is also intended to bear against a boundary surface of the plate opening. Furthermore, the two holding fingers 223 on their flanks 238 facing away from one another are widened beyond the adjacent side surfaces 14 and 16 of the insulating material block 11, so that these flanks 238 are suitable instead of the cams 30 of the first exemplary embodiment for contacting boundary surfaces of the plate opening in the corner parts thereof, un to secure the connector housing built into the panel opening against rotation in the panel opening.

Das in Fig. 6 veranschaulichte vierte Ausführungsbeispiel des erfindungsgemässen Steckverbinder-Gehäuses 10 weist konstruktive Merkmale des zweiten und des dritten Ausführungsbeispieles auf. An jeder der vier Seitenflächen 14 bis 17 des lsoliermaterialblockes 11 ist nur ein einziger Haltefinger 122 bzw. 323 vorhanden. Die an den Seitenflächen 14 und 16 angeordneten Haltefinger 122 haben je eine Breite, die mit der in gleicher Richtung gemessenen Breite des Isoliermaterialblockes 11 etwa übereineinstimmt. Die an den anderen Seitenflächen 15 und 17 angeordneten Haltefinger 323 hingegen sind je über die benachbarten Seitenflächen 14 und 16 hinaus verbreitert, so dass die Flanken 338 dieser Haltefinger 323 zum Anliegen an Begrenzungsflächen der Plattenöffnung in Eckpartien derselben geeignet sind, wie die Stirnflächen 31 der Nocken 30 der ersten Ausführungsbeispiels. Im übrigen weisen die Haltefinger 122 und 323 je eine von dem freien Ende ansteigende schrägfläche 124 bzw. 326 und je eine abfallende Stufe 125 bzw. 327 auf, wobei diese Schrägflächen und Stufen sich je über die ganze Breite des betreffenden Haltefingers erstrecken.The fourth exemplary embodiment of the connector housing 10 according to the invention illustrated in FIG. 6 has structural features of the second and the third exemplary embodiment. Only one holding finger 122 or 323 is provided on each of the four side surfaces 14 to 17 of the insulating material block 11. The holding fingers 122 arranged on the side surfaces 14 and 16 each have a width which corresponds approximately to the width of the insulating material block 11 measured in the same direction. The holding fingers 323 arranged on the other side surfaces 15 and 17, on the other hand, are each widened beyond the adjacent side surfaces 14 and 16, so that the flanks 338 of these holding fingers 323 are suitable for abutment on boundary surfaces of the plate opening in corner parts thereof, like the end surfaces 31 of the cams 30 of the first embodiment. Moreover, the holding fingers 122 and 323 each have an inclined surface 124 or 326 rising from the free end and a falling step 125 or 327, these inclined surfaces and steps each extending over the entire width of the holding finger in question.

Allen beschriebenen Ausführungsbeispielen gemeinsam ist der Vorteil, dass die an allen vier Seitenflächen 14 bis 17 des Isoliermaterialblockes 11 angeordneten Haltefinger 22, 23 bzw. 122, 23 bzw. 22, 223 bzw. 122, 323 dem in eine Plattenöffnung 20 eingesetzten Steckverbinder-Gehäuse 10 eine grössere Stabilität verleihen als dies bei bekannten Steckverbinder-Gehäusen der Fall ist, bei denen lediglich an zwei einander gegenüberliegenden Seitenflächen des Isoliermaterialblockes ähnliche Haltefinger vorhanden sind, die fingerartig ineinandergreifen. Die den Halt in der Plattenöffnung 20 gewährleistenden Stufen 25 und 27 bzw. 125 und 27 bzw. 125 und 327 weisen insgesamt grössere Flächen auf, die mit Randpartien der Plattenöffnung 20 zusammenarbeiten. Zudem haben die Stufen 25 bzw. 125 an den in der einen Richtung weisenden Haltefingern 22 bzw. 122 eine etwa gleich grosse Gesamtfläche wie die Stufen 27 bzw. 327 an den in entgegengesetzter Richtung weisenden Haltefingern 23, 223 bzw. 323, so dass die Verankerung des Steckverbinder-Gehäuses in der Plattenöffnung in beiden Richtungen gleich gut ist. Die beschriebene Anordnung und Ausbildung der Haltefinger des erfindungsgemässen Steckverbinder-Gehäuses erlaubt auch, die Abmessungen der Plattenöffnung 20 im Vergleich zu bisher etwas grösser zu machen, weil die Haltefinger dem Steckverbinder-Gehäuse eine ausreichend gute Stabilität in der Plattenöffnung zu verleihen imstande sind, selbst wenn die Nocken 30, 230 bzw. 235 oder die Flanken 238 bzw. 338 der Haltefinger 223 bzw. 323 nicht unmittelbar an Begrenzungsflächen der Plattenöffnung anliegen. Somit sind für die Abmessungen der Plattenöffnung 20 grössere Toleranzen als bisher zulässig.Common to all the exemplary embodiments described is the advantage that the holding fingers 22, 23 or 122, 23 or 22, 223 or 122, 323 arranged on all four side surfaces 14 to 17 of the insulating material block 11 have the connector housing 10 inserted into a panel opening 20 give greater stability than is the case with known connector housings, in which similar holding fingers are only present on two opposite side faces of the insulating material block and engage in one another like fingers. The steps 25 and 27 or 125 and 27 or 125 and 327 ensuring the hold in the plate opening 20 have larger areas overall, which cooperate with edge parts of the plate opening 20. In addition, the steps 25 and 125 on the holding fingers 22 and 122 pointing in one direction have an approximately equal total area as the steps 27 and 327 on the holding fingers 23, 223 and 323 pointing in the opposite direction, so that the anchoring the connector housing in the panel opening is equally good in both directions. The described arrangement and design of the holding fingers of the connector housing according to the invention also makes it possible to make the dimensions of the plate opening 20 somewhat larger than before, because the holding fingers are able to give the connector housing a sufficiently good stability in the plate opening, even if the cams 30, 230 or 235 or the flanks 238 or 338 of the holding fingers 223 or 323 do not bear directly against the boundary surfaces of the plate opening. Thus, larger tolerances than previously are permitted for the dimensions of the plate opening.

In Fig. 7 ist als weiteres Ausführungsbeispiel des erfindungsgemässen Steckverbinder-Gehäuses 10 eine vorteilhafte Variante der mit Bezug auf Fig. 5 beschriebenen Ausführungsform dargestellt. Soweit Uebereinstimmung besteht, sind in Fig. 7 die gleichen Bezugszeichen wie in Fig. 5 benutzt. Der Unterschied liegt lediglich darin, dass zwischen den an einer und derselben Seitenfläche 15 bzw. 17 des Isoliermaterialblockes 11 in einem Abstand voneinander angeordneten zwei Haitefingern 223 anstelle des Nockens 235 (Fig. 5) ein im wesentlichen hakenförmiges Verriegelungsorgan 340 vorhanden ist. Letzteres ist dazu bestimmt und geeignet, das Steckverbinder-Gehäuse 10 mit einem diesem angepassten zweiten Steckverbinder-Gehäuse 341 lösbar zu verriegeln. Zu diesem Zweck weist das zweite Steckverbinder-Gehäuse 341 an zwei einander entgegengesetzten Aussenflächen 342 und 343 je einen bügelförmigen Ansatz 344 auf, mit welchem das Verriegelungsorgan 340 des Steckverbinder-Gehäuses 10 in Eingriff treten kann. Das hakenförmige Verriegelungsorgan 340 selbst ist biegesteif, aber in seiner Mittelpartie mittels eines elastisch biegsamen Steges 345 mit der betreffenden Seitenfläche 15 bzw. 17 des Isoliermaterialblockes 11 verbunden. Hierdurch ist ein selbsttätiges Einschnappen des als Haken ausgebildeten Kopfes 346 des Verriegelungsorgans 340 im bügelförmigen Ansatz 344 ermöglicht, und durch Fingerdruck auf die vom Kopf 346 abgewandte Endpartie 347 lässt sich das Verriegelungsorgan 340 derart verschwenken, dass sein Kopf 346 ausser Eingriff mit dem Ansatz 344 gelangt und dann die Steckverbinder-Gehäuse 10 und 341 voneinander getrennt werden können.FIG. 7 shows an advantageous variant of the embodiment described with reference to FIG. 5 as a further exemplary embodiment of the connector housing 10 according to the invention. As far as there is agreement, the same reference numerals are used in Fig. 7 as in Fig. 5. The only difference is that there is an essentially hook-shaped locking member 340 between the two shark fingers 223 arranged on one and the same side surface 15 and 17 of the insulating material block 11 at a distance from one another instead of the cam 235 (FIG. 5). The latter is intended and suitable for releasably locking the connector housing 10 with a second connector housing 341 adapted to it. For this purpose, the second connector housing 341 has two bow-shaped projections 344 on two opposite outer surfaces 342 and 343, with which the locking member 340 of the connector housing 10 can engage. The hook-shaped locking member 340 itself is rigid, but is connected in its central part by means of an elastically flexible web 345 to the relevant side surface 15 or 17 of the insulating material block 11. This enables the head 346 of the locking member 340, which is designed as a hook, to snap into the bow-shaped extension 344 automatically, and by pressing the end part 347 facing away from the head 346, the locking member 340 can be pivoted such that its head 346 disengages from the extension 344 and then the connector housings 10 and 341 can be separated.
