Abstract

A protective casing for optical instruments, particularly a weatherproof casing with a casing shell (2), a casing axis A-A, a front wall (3) and a backwall (4) located on each end of the casing shell, and a casing support (9) located on the underside, which is attached to a stationary base (12). With at least one electric cable (23a) leading to a connector plug (11) located on the backwall (4). A detachable cable casing (20) is provided to house the cables out of sight, which extends from the base (12) to the connector plug (11), and together with the wall elements of the protective casing forms a closed cable conduit (21). At least one electrical cable (23a) runs inside the cable casing (20). A particular advantage is that the cable casing first runs between the casing support (9) and the cable casing (20) parallel to the surface of the casing shell (2), forming the first segment (21a) of the cable conduit (21), and then is led in an angle around the back bottom edge (22) of the backwall (4). From there it runs forming the second segment (21b) of the cable conduit (21) to the connector plug (11), overlapping the same.

Description

Die Erfindung betrifft ein Schutzgehäuse für optische Geräte, insbesondere ein Wetterschutzgehäuse für Video-Kameras von Überwachungsanlagen, mit einem Gehäusemantel, mit einer Gehäuseachse A-A, mit je einer am jeweiligen Ende des Gehäusemantels angeordneten Frontwand und Rückwand, mit einem an der Unterseite des Gehäusemantels befindlichen Gehäuseträger für die Befestigung des Schutzgehäuses auf einem ortsfesten Lager und mit mindestens einer elektrischen Leitung, die zu einer in der Rückwand befindlichen Anschlußstelle geführt ist.The invention relates to a protective housing for optical devices, in particular a weatherproof housing for video cameras of surveillance systems, with a housing jacket, with a housing axis AA, each with a front wall and rear wall arranged at the respective end of the housing jacket, with a housing support located on the underside of the housing jacket for attaching the protective housing to a fixed bearing and with at least one electrical line that leads to a connection point located in the rear wall.

Ein derartiges Schutzgehäuse ist durch die Firmendruckschrift "VIDEO-Security" der Anmelderin, Ausgabe 3/89, Seiten 8/9 bekannt. Schutzgehäuse dieser Art werden nach dem Anbringen vor Ort mittels einer Wandkonsole, einer Deckenaufhängung oder dergleichen mit den dafür vorgesehenen optischen Geräten und den zugehörigen elektrischen Einrichtungen bestückt. Bei Montage-, Wartungs- und Reparaturarbeiten sowie für den Fall einer nachträglichen Umrüstung müssen gegebenenfalls die elektrischen Anschlüsse gelöst oder gar die Leitungen ausgetauscht werden.Such a protective housing is known from the applicant's company publication "VIDEO-Security", issue 3/89, pages 8/9. Protective housings of this type are fitted after installation on site using a wall bracket, a ceiling suspension or the like with the optical devices and the associated electrical devices provided for this purpose. During assembly, maintenance and repair work, as well as in the event of retrofitting, the electrical connections may have to be disconnected or the cables even replaced.

Bei dem bekannten Schutzgehäuse verlaufen die elektrischen Leitungen von der Befestigungsstelle einer Wandkonsole unmittelbar zur Gehäuserückwand und von hier durch eine wetterfeste Leitungsdurchführung in das Innere des Schutzgehäuses. Wegen der erforderlichen Schwenkbarkeit und Neigbarkeit des Wetterschutzgehäuses (das Lager bildet eine Art kardanischer Aufhängung) müssen die Leitungen eine ausreichende Länge haben, um die erforderlichen Bewegungen im Bereich der Rückwand des Schutzgehäuses zuzulassen. Eine derartige "offene" Leitungsverlegung sieht nicht nur unschön aus, die frei zugänglichen Leitungen bieten auch eine prädestinierte Angriffsstelle für Sabotageakte.In the known protective housing, the electrical lines run from the fastening point of a wall bracket directly to the rear wall of the housing and from here through a weatherproof cable duct into the interior of the protective housing. Because of the required swiveling and inclinability of the weather protection housing (the bearing forms a kind of cardanic suspension), the lines must be of sufficient length to allow the necessary movements in the area of the rear wall of the protection housing. Such an "open" line laying not only looks ugly, the freely accessible lines also offer a predestined target for acts of sabotage.

Der Gehäusemantel kann dabei als Abschnitt eines stranggepreßten Rohres aus Leichtmetall hergestellt sein und beliebige Querschnittsformen aufweisen, beispielsweise quadratisch, rechteckig, achteckig oder rund. Frontwand und Rückwand sind bevorzugt als Gußteile aus Leichtmetall ausgebildet, und in der Frontwand ist ein Fenster angeordnet. Frontwand und Rückwand sind bevorzugt unter Zwischenlage von Dichtungen mit dem Gehäusemantel witterungsdicht verschraubt.The housing jacket can be made as a section of an extruded tube made of light metal and can have any cross-sectional shape, for example square, rectangular, octagonal or round. The front wall and rear wall are preferably cast parts made of light metal, and there is a window in the front wall arranged. The front wall and rear wall are preferably screwed weatherproof with the interposition of seals with the housing jacket.

Der Erfindung liegt die Aufgabe zugrunde, ein Schutzgehäuse der eingangs beschriebenen Gattung anzugeben, bei dem eine verdeckte Verlegung der Leitungen möglich ist, ohne daß ein übertriebener Aufwand beim Herstellen oder Lösen der Anschlüsse zu treiben ist.The invention has for its object to provide a protective housing of the type described above, in which a concealed laying of the lines is possible without excessive effort in making or loosening the connections.

Die Lösung der gestellten Aufgabe erfolgt bei dem eingangs angegebenen Schutzgehäuse erfindungsgemäß dadurch, daß vom Lager ausgehend bis zur Anschlußstelle ein abnehmbares Leitungsgehäuse mit U-förmig zueinander angeordneten Wandelementen vorgesehen ist, das zusammen mit Wandelementen des Schutzgehäuses einen geschlossenen Leitungskanal bildet, in dem die mindestens eine elektrische Leitung untergebracht ist und das die Anschlußstelle übergreift.The problem is solved in the protective housing specified at the outset according to the invention in that a removable conduit housing with U-shaped mutually arranged wall elements is provided starting from the bearing and which forms a closed conduit together with wall elements of the protective housing in which the at least one electrical line is housed and that overlaps the junction.

Durch das erfindungsgemäße Leitungsgehäuse wird unter Ausnutzung von Oberflächenteilen des Gehäusemantels bzw. des Gehäuseträgers und gegebenenfalls der Gehäuserückwand ein Leitungskanal gebildet, wobei das den Leitungskanal umschließende Leitungsgehäuse relativ rasch mit dem Schutzgehäuse verbunden und von diesem wieder getrennt werden kann, jedoch nicht innerhalb einer so kurzen Zeitspanne, wie dies zum Abschneiden der Leitungen erforderlich wäre.By means of the line housing according to the invention, a line duct is formed using surface parts of the housing shell or the housing carrier and optionally the rear wall of the housing, the line housing enclosing the line duct being able to be connected to and separated from the protective housing relatively quickly, but not within such a short period of time as would be required to cut the lines.

Durch die erfindungsgemäße bauliche Vereinigung des Leitungsgehäuses mit dem Schutzgehäuse entsteht ein ansprechender optischer Gesamteindruck mit einer geschlossenen Außenfläche der Gesamtanordnung, so daß auch die ansonsten mögliche Schmutzansammlung auf ein Minimum reduziert wird.The structural union according to the invention with the protective housing creates an appealing overall visual impression with a closed outer surface of the overall arrangement, so that the otherwise possible dirt accumulation is reduced to a minimum.

Dadurch, daß die Leitung(en) über das Lager geführt ist (sind), ist eine Verlegung auf kürzestem Wege möglich. Ferner braucht bei einem Steckeranschluß und beim Abbau des Gehäuses vom Lager der Stecker nicht von der Leitung getrennt werden, da die Leitung an dieser Stelle nicht durch eine enge Öffnung gezogen werden muß.Because the cable (s) is (are) routed through the bearing, it can be laid in the shortest possible way. Furthermore, with a plug connection and when removing the housing from the bearing, the plug need not be separated from the line, since the line does not have to be pulled through a narrow opening at this point.

Es ist dabei zwecks Herstellung einer Zugänglichkeit der Anschlußstelle von der Rückseite des Gehäuses her besonders vorteilhaft, ein Leitungsgehäuse vorzusehen, das zunächst unter Bildung eines ersten Abschnitts des Leitungskanals zwischen Gehäuseträger und Leitungsgehäuse parallel zur Oberfläche des Gehäusemantels verläuft, anschließend in einem Winkel um die hintere Unterkante der Rückwand herumgeführt ist und unter Bildung eines zweiten Abschnitts des Leitungskanals die in der Rückwand liegende Anschlußstelle übergreift.It is particularly advantageous in order to make the connection point accessible from the rear of the housing, to provide a cable housing which first runs parallel to the surface of the housing shell, forming a first section of the cable duct between the housing support and the cable housing, and then at an angle around the rear lower edge the rear wall is guided around and overlaps the connection point located in the rear wall to form a second section of the conduit.

Es ist dabei weiterhin besonders vorteilhaft, wenn das Leitungsgehäuse eine senkrechte Mittenebene aufweist, die durch die Gehäuseachse verläuft, und wenn das Leitungsgehäuse in Bezug auf Querschnitte, die senkrecht zu dieser Mittenebene verlaufen, auf mindestens drei Umfangsseiten durch U-förmig zueinander angeordnete Wandelemente geschlossen ist, von denen zwei die Schenkel bilden, deren freien Enden dem Gehäusemantel zugekehrt sind, und von denen das dritte Wandelement das Joch des "U" bildet.It is furthermore particularly advantageous if the line housing has a vertical center plane which runs through the housing axis, and if the line housing is closed on at least three circumferential sides with respect to cross sections which run perpendicular to this center plane by means of wall elements arranged in a U-shape with respect to one another , two of which form the legs, the free ends of which face the housing shell, and of which the third wall element forms the yoke of the "U".

Es ist bei einer entsprechenden Ausbildung der Gehäuserückwand von wiederum besonderem Vorteil, wenn das das Joch bildende Wandelement in einer Schnittebene, die mit der Mittenebene zusammenfällt, V-förmig ausgebildet ist und einen Bodenteil und einen Rückwandteil bildet, wobei der zwischen Bodenteil und Rückwandteil liegende Scheitelbereich abgerundet ausgebildet ist.With a corresponding design of the rear wall of the housing, it is again particularly advantageous if the wall element forming the yoke is V-shaped in a sectional plane that coincides with the central plane and forms a base part and a rear wall part, the apex region lying between the base part and rear wall part is rounded.

Bei der gegebenen Lage der Anschlußstelle läßt sich eine besonders kompakte Raumform des Leitungsgehäuses dann erzielen, wenn

  • a) die Rückwand des Gehäuses auf ihrer dem Gehäusemantel abgekehrten Seite eine Verschlußwand besitzt, die in einer vertikalen Schnittebene unter Bildung einer nach außen geöffneten prismatischen Ausnehmung mit waagrechter Achse V-förmig abgewinkelt ausgebildet ist, wobei der Öffnungswinkel des "V" 90 Grad beträgt und beide Schenkel des "V" unter einem spitzen Winkel zur Gehäuseachse A-A verlaufen,
  • b) in dem den oberen Schenkel des "V" bildenden Wandelement ein erster Steckverbindungsteil vorgesehen ist,
  • c) ein zweiter Steckverbindungsteil, der mit dem ersten Steckverbindungsteil eine Kupplung bildet, in einem Steckergehäuse angeordnet ist, das von außen abgedichtet an das obere Wandelement der prismatischen Ausnehmung in der Rückwand angesetzt ist, und wenn
  • d) der Rückwandteil des Leitungsgehäuses mit dem Steckergehäuse verbunden ist.
Given the position of the connection point, a particularly compact spatial shape of the line housing can be achieved if
  • a) the rear wall of the housing on its side facing away from the housing jacket has a closure wall which is formed in a vertical section plane to form an outwardly open prismatic recess with a horizontal axis V-shaped, the opening angle of the "V" being 90 degrees and both legs of the "V" run at an acute angle to the housing axis AA,
  • b) a first plug connection part is provided in the wall element forming the upper leg of the "V",
  • c) a second plug-in connection part, which forms a coupling with the first plug-in connection part, is arranged in a plug housing, which, from the outside, is sealingly attached to the upper wall element of the prismatic recess in the rear wall, and if
  • d) the rear wall part of the cable housing is connected to the connector housing.

In Figur 1 ist ein Wetterschutzgehäuse 1 für Video-Kameras gezeigt, das einen rohrförmigen Gehäusemantel 2 aufweist, der aus einem Abschnitt eines auf dem Umfang geschlossenen Leichtmetall-Strangprofils besteht. Der Querschnitt ist in seinem unteren Bereich in Figur 10 dargestellt und wird im Zusammenhang damit noch näher erläutert.FIG. 1 shows a weather protection housing 1 for video cameras, which has a tubular housing jacket 2, which consists of a section of an extruded light metal profile closed on the circumference. The cross section is shown in its lower region in FIG. 10 and is explained in more detail in connection therewith.

Der Gehäusemantel 2 ist vorn und hinten durch eine Frontwand 3 und eine Rückwand 4 dicht verschlossen. Zum Schutzgehäuse gehört ferner ein Schutzdach 5, das den Gehäusemantel 2 auf seiner Oberseite 6 und von oben auf dem größten Teil seiner beiden Seitenwände 7 unter Belassung eines Luftspalts 8 umgibt (Figur 15). Die Länge des Schutzdaches 5 ist dabei so gewählt, daß es sowohl über die Vorderseite der Frontwand 3 als auch über die Rückseite der Rückwand 4 übersteht (Figur 1).The housing jacket 2 is sealed at the front and rear by a front wall 3 and a rear wall 4. The protective housing also includes a protective roof 5, which surrounds the housing shell 2 on its upper side 6 and from above on most of its two side walls 7, leaving an air gap 8 (FIG. 15). The length of the canopy 5 is chosen so that it protrudes both over the front of the front wall 3 and over the back of the rear wall 4 (Figure 1).

Zum Schutzgehäuse 1 gehört ferner ein Gehäuseträger 9, der anhand von Figur 10 noch näher erläutert werden wird. Der Gehäuseträger 9 ist als Schiene über die Länge des Gehäusemantels 2 durchgehend starr mit der Rückwand 4 verbunden und knapp unterhalb der Unterseite 10 des Gehäusemantels 2 angeordnet.The protective housing 1 also includes a housing support 9, which will be explained in more detail with reference to FIG. 10. The housing support 9 is connected rigidly to the rear wall 4 as a rail over the length of the housing shell 2 and is arranged just below the underside 10 of the housing shell 2.

Gemäß Figur 1 ist das Schutzgehäuse auf einem Lager 12 befestigt, das aus zwei Lagerböcken 13 und 14 besteht, die durch eine Neigeachse 15 miteinander verbunden sind. Der Gehäuseträger 9 besitzt einen mittigen Längsschlitz 16 und ist dadurch in Richtung der Gehäuseachse A-A auf dem oberen Lagerbock 13 verschiebbar. Die Festlegung erfolgt über nicht dargestellte Spannschrauben und wird in der Weise getroffen, daß sich die Neigeachse 15 möglichst genau unter dem Schwerpunkt des vollständig bestückten Schutzgehäuses befindet.According to FIG. 1, the protective housing is fastened on a bearing 12, which consists of two bearing blocks 13 and 14, which are connected to one another by a tilt axis 15. The housing support 9 has a central longitudinal slot 16 and is thereby displaceable on the upper bearing block 13 in the direction of the housing axis A-A. The determination is made via clamping screws, not shown, and is made in such a way that the tilt axis 15 is as precisely as possible under the center of gravity of the fully equipped protective housing.

Der untere Lagerbock 14 ist um eine senkrechte Schwenkachse "S" drehbar an einer Wandkonsole 17 befestigt, die mit einer Wand 18 verschraubt ist.The lower bracket 14 is rotatably mounted about a vertical pivot axis "S" on a wall bracket 17 which is screwed to a wall 18.

Die erforderlichen elektrischen Leitungen verlaufen in der Wandkonsole 17 sowie in Hohlräumen in den Lagerböcken 13 und 14 und - ausgehend vom Lager 12 unterhalb des Gehäuseträgers 9 (Figur 10) und unterhalb der Unterseite der Rückwand 4.The required electrical lines run in the wall bracket 17 and in cavities in the bearing blocks 13 and 14 and - starting from the bearing 12 below the housing support 9 (FIG. 10) and below the underside of the rear wall 4.

In der Rückwand 4 ist eine Anschlußstelle 11 vorgesehen, auf die nachfolgend im Zusammenhang mit Figur 2 noch näher eingegangen wird. Ausgehend vom Lager 12 ist bis zur Anschlußstelle 11 ein Leitungsgehäuse 20 vorgesehen, das zunächst unter Bildung eines ersten Abschnitts 21a eines Leitungskanals 21 zwischen dem Gehäuseträger 9 und dem Leitungsgehäuse 20 parallel zur Oberfläche des Gehäusemantels 2 verläuft. Anschließend ist das Leitungsgehäuse in einem Winkel um die hintere Unterkante 22 der Rückwand 4 herumgeführt und übergreift unter Bildung eines zweiten Abschnitts 21b des Leitungskanals 21 die in der Rückwand 4 liegende Anschlußstelle 11. Dies geschieht in der Weise, daß die elektrischen Leitungen 23a, 23b und 23c, ausgehend vom Lager 12 bis zur Anschlußstelle 11 innerhalb des Leitungsgehäuses 20 geführt sind (siehe auch Figur 10).A connection point 11 is provided in the rear wall 4, which will be discussed in more detail below in connection with FIG. 2. Starting from camp 12 is up to Connection point 11 a line housing 20 is provided, which initially runs parallel to the surface of the housing shell 2, forming a first section 21a of a line channel 21 between the housing support 9 and the line housing 20. The line housing is then guided at an angle around the rear lower edge 22 of the rear wall 4 and overlaps the connection point 11 located in the rear wall 4 to form a second section 21b of the line channel 21. This is done in such a way that the electrical lines 23a, 23b and 23c, starting from the bearing 12 to the connection point 11 within the line housing 20 (see also Figure 10).

Wie deutlicher aus Figur 2 in Verbindung mit Figur 9 hervorgeht, besitzt das Leitungsgehäuse 20 eine senkrechte Mittenebene, die durch die Gehäuseachse A-A verläuft, also mit der Schnittebene in Figur 2 zusammenfällt. In Bezug auf Querschnitte, die senkrecht zu dieser Mittenebene verlaufen, ist das Gehäuse 20 auf mindestens drei Umfangsseiten durch U-förmig zueinander angeordnete Wandelemente 20a, 20b und 20c geschlossen. Die beiden Wandelemente 20a und 20c bilden die Schenkel des "U", deren freie Enden dem Gehäusemantel 2 und der Rückwand 4 zugekehrt sind. Das dritte Wandelement 20b bildet das Joch des "U". Wegen des räumlichen Verlaufs der Unterseiten von Gehäusemantel 2 und Rückwand 4 und der Rückseite der Rückwand ist die Länge der Schenkel unterschiedlich und abgestuft, wie dies aus Figur 9 hervorgeht.As can be seen more clearly from FIG. 2 in conjunction with FIG. 9, the line housing 20 has a vertical center plane which runs through the housing axis A-A, that is to say coincides with the sectional plane in FIG. 2. With regard to cross sections that run perpendicular to this central plane, the housing 20 is closed on at least three circumferential sides by wall elements 20a, 20b and 20c arranged in a U-shape with respect to one another. The two wall elements 20a and 20c form the legs of the "U", the free ends of which face the housing shell 2 and the rear wall 4. The third wall element 20b forms the yoke of the "U". Because of the spatial course of the undersides of housing shell 2 and rear wall 4 and the rear of the rear wall, the length of the legs is different and graded, as can be seen from FIG. 9.

Aus den Figuren 1, 2 und 9 ist deutlicher zu entnehmen, daß das das Joch bildende Wandelement 20b in einer Schnittebene, die mit der besagten Mittenebene zusammenfällt, V-förmig ausgebildet ist und einen Bodenteil 24 und einen Rückwandteil 25 bildet, wobei der zwischen Bodenteil und Rückwandteil liegende Scheitelbereich 26 abgerundet ausgebildet ist.It can be seen more clearly from FIGS. 1, 2 and 9 that the wall element 20b forming the yoke is in one Section plane which coincides with said center plane, is V-shaped and forms a base part 24 and a rear wall part 25, the apex region 26 lying between the base part and the rear wall part being rounded.

Die die Schenkel bildenden Wandelemente 20a und 20c sind entlang ihrer oberen, parallelen Kanten 27 im Bereich des Gehäusemantels 2 mit ersten Rücksprüngen 28 für den Eingriff von Längsrippen 29 versehen, die an der Unterseite 10 des Gehäusemantels 2 angeordnet sind (siehe auch Figur 10).The wall elements 20a and 20c forming the legs are provided along their upper, parallel edges 27 in the region of the housing shell 2 with first recesses 28 for the engagement of longitudinal ribs 29 which are arranged on the underside 10 of the housing shell 2 (see also FIG. 10).

Die die Schenkel bildenden Wandelemente 20a und 20c sind an den im Bereich des Gehäusemantels 2 liegenden freien Enden des Leitungsgehäuses 20 mit zweiten Rücksprüngen 30 versehen, die zum Einschieben in entsprechende komplementäre Rücksprünge des oberen Lagerbocks 13 dienen. Dieses Zusammenwirken zwischen dem Leitungsgehäuse 20 und dem oberen Lagerbock 13 ist Figur 1 zu entnehmen, auf Einzelheiten bei der Gestaltung des Lagerbocks wird im Zusammenhang mit den Figuren 11 bis 14 noch näher eingegangen.The wall elements 20a and 20c forming the legs are provided with second recesses 30 on the free ends of the line housing 20 in the area of the housing shell 2, which recesses 30 serve for insertion into corresponding complementary recesses of the upper bearing block 13. This interaction between the line housing 20 and the upper bearing block 13 can be seen in FIG. 1, details in the design of the bearing block are discussed in more detail in connection with FIGS. 11 to 14.

Die Beschaffenheit der Anschlußstelle 11 wird im Zusammenhanghang mit Figur 2 nachfolgend näher erläutert:The nature of the connection point 11 is explained in more detail below in connection with FIG. 2:

Die Rückwand besitzt auf ihrer dem Gehäusemantel 2 abgekehrten Seite eine Verschlußwand 31, die in einer vertikalen Schnittebene durch die Achse A-A eine nach außen geöffnete prismatische Ausnehmung 32 bildet (Figur 3), deren Achse waagrecht verläuft. Die prismatische Ausnehmung wird von einem oberen Wandelement 33 und von einem unteren Wandelemente 34 begrenzt, die unter einem Winkel von 90 Grad zueinander angeordnet sind und beide unter einem spitzen Winkel zur Gehäuseachse A-A verlaufen. Die Wandelemente 33 und 34 bilden die Schenkel eines "V", und die Scheitellinie 35 dieses "V" verläuft waagrecht (Figur 3).The rear wall has, on its side facing away from the housing jacket 2, a closure wall 31 which forms a prismatic recess 32 open to the outside in a vertical sectional plane through the axis AA (FIG. 3), the axis of which extends horizontally. The prismatic Recess is delimited by an upper wall element 33 and by a lower wall element 34, which are arranged at an angle of 90 degrees to one another and both run at an acute angle to the housing axis AA. The wall elements 33 and 34 form the legs of a "V", and the apex line 35 of this "V" runs horizontally (FIG. 3).

Das obere Wandelement 33 besitzt eine rechteckige Ausnehmung 36, in der ein erster Steckverbindungsteil 37 (Vaterteil) angeordnet ist. Ein zweiter Steckverbindungsteil 38 ist in einem Steckergehäuse 39 befestigt, das anhand der Figuren 4 bis 7 noch näher erläutert wird. Die beiden Steckverbindungsteile 37 und 38 bilden miteinander eine Kupplung. Die Steckrichtung verläuft senkrecht zu einer zwischen den Steckverbindungsteilen 37 und 38 befindlichen, nicht näher bezeichneten Trennfuge, bzw. senkrecht zum oberen Wandelement 33.The upper wall element 33 has a rectangular recess 36, in which a first plug connection part 37 (male part) is arranged. A second connector part 38 is fastened in a connector housing 39, which is explained in more detail with reference to FIGS. 4 to 7. The two connector parts 37 and 38 form a coupling with each other. The plug-in direction runs perpendicular to a separating joint (not specified in more detail) between the plug-in connection parts 37 and 38, or perpendicular to the upper wall element 33.

Wie aus den Figuren 1, 2 und 15 hervorgeht, ist das Steckergehäuse 39 von außen abgedichtet auf die Rückwand 4 aufgesetzt, und zwar mit dem oberen Wandelement 33 der prismatischen Ausnehmung 32 unter Zwischenschaltung einer nicht dargestellten Dichtung verschraubt. Ferner ist das Rückwandteil 25 des Leitungsgehäuses 20 mit dem Steckergehäuse 39 verbunden, und zwar über eine Schwalbenschwanzverbindung 40, die gleichfalls nachstehend noch näher erläutert wird.As can be seen from FIGS. 1, 2 and 15, the plug housing 39 is placed on the rear wall 4, sealed from the outside, and is screwed to the upper wall element 33 of the prismatic recess 32 with the interposition of a seal, not shown. Furthermore, the rear wall part 25 of the line housing 20 is connected to the plug housing 39, specifically via a dovetail connection 40, which is also explained in more detail below.

Wie sich aus den Figuren 2 und 3 ergibt, besitzt die Rückwand 4 auf der dem Gehäusemantel 2 abgekehrten Seite in ihrem oberen Bereich und an den Seiten einen vorspringenden, zur Gehäuseachse A-A parallelen Rand 41 und eine zur Steckrichtung der Steckverbindung parallel und zum oberen Wandelement 33 der prismatischen Ausnehmung 32 senkrecht verlaufende und bis zum Rand 41 reichende Auflagefläche 42.As can be seen from FIGS. 2 and 3, the rear wall 4 has on the side facing away from the housing jacket 2 in its upper region and on the sides a projecting edge 41 parallel to the housing axis AA and a support surface 42 running parallel to the plug-in direction of the plug connection and perpendicular to the upper wall element 33 of the prismatic recess 32 and reaching to the edge 41.

Das Steckergehäuse 39 besitzt auf der dem Steckverbindungsteil 38 abgekehrten Seite eine parallel zu der besagten Steckrichtung verlaufende Abdeckplatte 43, die kongruent auf der Auflagefläche 42 aufliegt. Ferner ist die Abdeckplatte 43 auf ihrer Außenseite 43a mit Mitteln zum Befestigen des Rückwandteils 25 des Leitungsgehäuses 20 versehen, nämlich mit einer Schwalbenschwanzführung 40a. Die Schwalbenschwanzführung 40a dient zum Einschieben eines zungenförmigen Fortsatzes 25a des Rückwandteils 25, wobei die Einschubrichtung der Schwalbenschwanzführung 40a in der Mittenebene des Leitungsgehäuses 20 verläuft. Dieses Zusammenwirken ist besonders deutlich der Figur 15 zu entnehmen.The connector housing 39 has, on the side facing away from the plug connection part 38, a cover plate 43 which runs parallel to the said plug direction and which lies congruently on the contact surface 42. Furthermore, the cover plate 43 is provided on its outer side 43a with means for fastening the rear wall part 25 of the line housing 20, namely with a dovetail guide 40a. The dovetail guide 40a is used to insert a tongue-shaped extension 25a of the rear wall part 25, the direction of insertion of the dovetail guide 40a running in the center plane of the line housing 20. This interaction can be seen particularly clearly in FIG. 15.

Es versteht sich, daß das Steckergehäuse 39 nur dann mit der Rückwand 4 verschraubt werden kann, wenn es aus der in Figur 4 gezeigten Stellung um eine senkrechte Achse um 180 Grad in die Stellung gemäß Figur 6 gedreht wurde. Diese Stellung ist auch in Figur 15 dargestellt.It goes without saying that the plug housing 39 can only be screwed to the rear wall 4 if it has been rotated from the position shown in FIG. 4 about a vertical axis by 180 degrees into the position according to FIG. 6. This position is also shown in Figure 15.

Gemäß den Figuren 4 bis 7 besitzt das Steckergehäuse 39 innen einen Hohlraum 44 für die Leitungsführung. Drei dieser Adern 45 sind in Figur 2 angedeutet. Vom oberen Steckverbindungsteil 37 führen Adern 45a, von denen nur drei dargestellt sind, zu einem Elektronikbauteil 45b, das beispielhaft ein Netzgerät ist.According to FIGS. 4 to 7, the plug housing 39 has a cavity 44 inside for the cable routing. Three of these wires 45 are indicated in Figure 2. From the upper connector 37 lead 45a, of which only three are shown, to an electronic component 45b, which is an example of a power supply.

Das Steckergehäuse 39 besitzt weiterhin auf seiner Oberseite beiderseits des Hohlraums 44 Schulterflächen 46 mit Gewindebohrungen 47 für die Auflage und Befestigung des zugehörigen Steckverbindungsteils 38 (Figur 2). Ferner besitzt das Steckergehäuse 39 eine die obere Mündung des Hohlraums 44 umgebende Dichtfläche 48 für die Verbindung mit dem gegenüberliegenden Wandelement 33 der prismatischen Ausnehmung 32. In dieser Dichtfläche 48 ist eine auf dem Umfang geschlossene (rechteckige) Dichtungsnut 49 angeordnet (Figur 7).The connector housing 39 also has shoulder surfaces 46 on its upper side on both sides of the cavity 44 with threaded bores 47 for the support and fastening of the associated connector part 38 (FIG. 2). Furthermore, the plug housing 39 has a sealing surface 48 surrounding the upper mouth of the cavity 44 for connection to the opposite wall element 33 of the prismatic recess 32. In this sealing surface 48 there is a (rectangular) sealing groove 49 which is closed on the circumference (FIG. 7).

Auf seiner Unterseite besitzt das Steckergehäuse 39 eine Gewindebohrung 50 für das Einschrauben einer Stopfbuchsverschraubung 51, die in Figur 2 gezeigt ist. Die Gewindebohrung 50 ist auf einem Teil ihrer Länge von einem nach unten gerichteten, nicht näher bezeichneten Kragen, umgeben. Weiterhin ist auf der gleichen Unterseite außerhalb des besagten Kragens eine ebene Anschlagfläche 52 für zwei Stirnkanten 53 des Leitungsgehäuses 20 angeordnet (siehe auch Figur 9). An seinen beiden Außenseiten ist das Steckergehäuse 39 mit zwei zur Steckrichtung parallel verlaufenden Schraubkanälen 54 für die Schraubverbindung mit dem der Dichtfläche 48 gegenüberliegenden Wandelement 33 versehen. Die zugehörigen Gewindebohrungen 55 sind in Figur 3 dargestellt. Die in Figur 3 gezeigten Schraubkanäle 56 dienen zum Verschrauben der Rückwand 4 mit dem Gehäusemantel 2, was hier jedoch nicht weiter von Bedeutung ist.On its underside, the connector housing 39 has a threaded bore 50 for screwing in a gland screw connection 51, which is shown in FIG. 2. The threaded bore 50 is surrounded over part of its length by a downward-pointing collar, not specified. Furthermore, a flat stop surface 52 for two end edges 53 of the line housing 20 is arranged on the same underside outside of the said collar (see also FIG. 9). On its two outer sides, the plug housing 39 is provided with two screw channels 54, which run parallel to the plug direction, for the screw connection with the wall element 33 opposite the sealing surface 48. The associated threaded holes 55 are shown in Figure 3. The screw channels 56 shown in FIG. 3 are used to screw the rear wall 4 to the housing jacket 2, which is of no further importance here.

Wie aus den Figuren 8 und 9 noch näher hervorgeht, ist das obere Ende des zungenförmigen Fortsatzes 25a des Rückwandteils 25 über Rastelemente 25b mit der Schwalbenschwanzführung 40a verbunden. Diese besitzt an der entsprechenden Stelle komplementäre Rastnasen 40b.As can be seen in more detail from FIGS. 8 and 9, the upper end of the tongue-shaped extension 25a of the rear wall part 25 is connected to the dovetail guide 40a via latching elements 25b. This has complementary locking lugs 40b at the corresponding point.

Figur 10 ist noch zu entnehmen, in welcher Weise das Leitungsgehäuse 20 an die Unterseite 10 des Gehäusemantels 2 angesetzt ist. Zwischen dem Gehäuseträger 9 und den L-förmigen Längsrippen 29 befindet sich auf jeder Seite des Gehäuseträgers 9 ein parallelwandiger Spalt, in den das Leitungsgehäuse 20 mit den Stellen eingesetzt ist, an denen sich die ersten Rücksprünge 28 befinden. Die oberen verjüngten Schenkelenden stoßen alsdann mit ihren Längskanten 27 an die untere Begrenzungsfläche des Gehäusemantels 2 zwischen den Längsrippen 29 an, so daß ein seitliches Verschieben unmöglich ist. Durch eine nicht gezeigte Zugschraube kann das Leitungsgehäuse 20 gegen den Gehäusemantel 2 verspannt werden.FIG. 10 also shows the manner in which the line housing 20 is attached to the underside 10 of the housing jacket 2. Between the housing support 9 and the L-shaped longitudinal ribs 29 there is a parallel-walled gap on each side of the housing support 9, into which the line housing 20 is inserted with the locations at which the first recesses 28 are located. The upper tapered leg ends then abut with their longitudinal edges 27 on the lower boundary surface of the housing shell 2 between the longitudinal ribs 29, so that lateral displacement is impossible. The cable housing 20 can be clamped against the housing jacket 2 by a tension screw, not shown.

Einzelheiten des oberen Lagerbocks 13 werden anhand der Figuren 11 bis 14 wie folgt erläutert: Der obere Lagerbock 13 ist in Bezug auf eine durch die Neigeachse 15 gelegte Symmetrieebene U-förmig ausgebildet und besitzt eine oben liegende, das Joch des "U" bildende Flanschplatte 57 für die Auflage des Gehäuseträgers 9 und zwei seitliche, zueinander parallele Schenkel 58 mit Bohrungen 59 für die Neigeachse. Durch die gestrichelten Linien in den Figuren 12, 13 und 14 ist deutlich gemacht, daß die unterhalb der Flanschplatte 57 liegenden Ränder auf der Innenseite mit Rücksprüngen 60, 61 und 62 für das Einsetzen der komplementären Rücksprünge 30 am freien Ende des Bodenteils 24 des Leitungsgehäuses 20 versehen sind. Dadurch greift das Leitungsgehäuse 20 mit seinem unteren freien Ende formschlüssig in den Lagerbock 13 ein, so daß auch an dieser Stelle eine weitgehende Abdichtung erfolgt. Der Lagerbock 13 wird durch Schrauben mit dem Gehäuseträger 9 verspannt, die durch die Bohrungen 63 hindurchgeführt werden. Diese Schrauben sind in gelöstem Zustand in dem Längsschlitz 16 (Figur 10) verschiebbar. Langlöcher 64 in der Flanschplatte 57 dienen beispielsweise dazu, hier nicht gezeigte Leitungen in Hohlräume des Gehäuseträgers 9 hineinzuführen, wenn sich ein Bedarf hierfür ergibt. In diesem Falle müßte aber ein Steckverbindungsteil von der zugehörigen Leitung abmontiert werden, wenn das Schutzgehäuse mit dem Gehäuseträger an die Leitung angeschlossen oder von dieser getrennt werden soll.Details of the upper bearing block 13 are explained as follows with reference to FIGS. 11 to 14: The upper bearing block 13 is U-shaped in relation to a plane of symmetry through the tilt axis 15 and has an overhead flange plate 57 which forms the yoke of the "U" for the support of the housing support 9 and two lateral, mutually parallel legs 58 with bores 59 for the tilt axis. The dashed lines in Figures 12, 13 and 14 make it clear that the edges below the flange plate 57 on the inside with recesses 60, 61 and 62 for the insertion of the complementary recesses 30 are provided at the free end of the bottom part 24 of the line housing 20. As a result, the cable housing 20 engages with its lower free end in a form-fitting manner in the bearing block 13, so that extensive sealing also takes place at this point. The bearing block 13 is clamped to the housing support 9 by screws which are passed through the bores 63. In the released state, these screws can be displaced in the longitudinal slot 16 (FIG. 10). Elongated holes 64 in the flange plate 57 serve, for example, to lead lines (not shown here) into cavities in the housing support 9 if there is a need for this. In this case, however, a plug connection part would have to be removed from the associated line if the protective housing is to be connected to the line or separated from the line carrier.

In den Figuren 16 bis 19 ist ein zweites Ausführungsbeispiel der Erfindung beschrieben; für übereinstimmende oder analoge Bauteile wurden gleiche Bezugszeichen verwendet. Für unterschiedliche Bauteile wurde zu den Bezugszeichen die Zahl 100 addiert.A second exemplary embodiment of the invention is described in FIGS. 16 to 19; the same reference numerals have been used for matching or analog components. The number 100 was added to the reference symbols for different components.

Dieses Ausführungsbeispiel unterscheidet sich von demjenigen gemäß den Figuren 1 bis 15 im wesentlichen dadurch, daß die Steckrichtung der Steckverbindung senkrecht zur Gehäuseachse A-A verläuft. Dadurch kann die Verschlußwand 131 der Rückwand 104 - abgesehen von den Kühlrippen 131a - eben ausgebildet werden. Im unteren Bereich dieser Rückwand 104 befindet sich eine Ausnehmung 136, deren Hauptebene gleichfalls senkrecht zur Achse A-A verläuft. Diese Ausnehmung mündet in die untere ebene Begrenzungsfläche der Rückwand 104. Im Bereich der Mündung der Ausnehmung 136 befindet sich ein erstes Steckverbindungsteil 37, dessen Leitungen bzw. Adern nur angedeutet sind. An die Unterseite von Gehäusemantel 2 und Rückwand 104 ist ein Leitungsgehäuse 120 angesetzt, das einen im wesentlichen geradlinigen Leitungskanal 121 umschließt. Der hintere Teil des Leitungsgehäuses 120 ist als Steckergehäuse 139 ausgebildet und mit diesem einstückig geformt. Das Steckergehäuse 139 ist nach oben hin durch ein Wandelement 65 begrenzt, in dem sich eine Ausnehmung 66 befindet, in die ein zweites Steckverbindungsteil 38 eingesetzt ist. Die Befestigung erfolgt dabei mittels der Schrauben 67 auf Schulterflächen 146. Die Ausnehmung 66 ist von einer auf dem Umfang geschlossenen Dichtungsnut 149 umgeben, in die eine hier nicht näher bezeichnete Profildichtung eingesetzt ist. Mittels Schrauben und entsprechender Schraubkanäle 154 ist das Leitungsgehäuse 20 gegen die Unterseite der Rückwand 104 verschraubt. Die Trennfuge zwischen dieser Unterseite und dem Steckergehäuse 139 verläuft, wie aus Figur 16 ersichtlich, parallel zur Achse A-A.This exemplary embodiment differs from that according to FIGS. 1 to 15 essentially in that the plug-in direction of the plug connection is perpendicular to the housing axis AA. As a result, the closure wall 131 of the rear wall 104 - apart from the cooling fins 131a - can be made flat. In the lower region of this rear wall 104 there is a recess 136, the main plane of which is also perpendicular to the axis AA runs. This recess opens into the lower flat boundary surface of the rear wall 104. In the region of the opening of the recess 136 there is a first plug-in connection part 37, the lines or wires of which are only indicated. A cable housing 120 is attached to the underside of the housing jacket 2 and the rear wall 104, which encloses an essentially straight line channel 121. The rear part of the cable housing 120 is designed as a plug housing 139 and is formed in one piece with it. The plug housing 139 is delimited at the top by a wall element 65, in which there is a recess 66, into which a second plug connection part 38 is inserted. The fastening is carried out by means of the screws 67 on shoulder surfaces 146. The recess 66 is surrounded by a sealing groove 149 which is closed on the circumference and into which a profile seal, not shown here, is inserted. The cable housing 20 is screwed against the underside of the rear wall 104 by means of screws and corresponding screw channels 154. The parting line between this underside and the plug housing 139 runs, as can be seen in FIG. 16, parallel to the axis AA.

Das Leitungsgehäuse 120 setzt sich rechts vom Steckergehäuse 139 durch ein Bodenteil 144 und zwei im rechten Winkel davon abstehende Seitenwände 120a und 120b fort, die zusammen einen U-förmigen Querschnitt darstellen, bei dem der Bodenteil 124 das Joch bildet. In diesem Bereich ist das Leitungsgehäuse 120 in Analogie zu demjenigen Leitungsgehäuse 20 ausgebildet, das in Figur 9 gezeigt ist. Die Analogie gilt auch für den Eingriff des dem Steckergehäuse 139 abgekehrten Endes in den oberen Lagerbock 13 des Lagers 12, so daß bezüglich dieser Details auf eine Wiederholung verzichtet werden kann. Es versteht sich noch, daß das hintere Ende des Leitungsgehäuses 120 bzw. des Steckergehäuses 139 mit der Verschlußwand 131 fluchtet, und zwar auch hinsichtlich der Kühlrippen 131a. Von dem Steckergehäuse 120 sind in diesem Zusammenhang nur noch die oberen Kanten 127 und die Rücksprünge 128 erwähnenswert, die den Eingriff in die Längsrippen 29 bzw. den Lagerbock 13 ermöglichen.The cable housing 120 continues to the right of the connector housing 139 through a base part 144 and two side walls 120a and 120b protruding therefrom at right angles, which together form a U-shaped cross section, in which the base part 124 forms the yoke. In this area, the line housing 120 is formed in analogy to that line housing 20 which is shown in FIG. 9. The analogy also applies to the engagement of the end facing away from the plug housing 139 in the upper end Bearing block 13 of the bearing 12, so that a repetition can be omitted with regard to these details. It also goes without saying that the rear end of the line housing 120 or the plug housing 139 is flush with the closure wall 131, even with regard to the cooling fins 131a. In this context, only the upper edges 127 and the recesses 128 of the connector housing 120 are worth mentioning, which enable the engagement in the longitudinal ribs 29 or the bearing block 13.

In Figur 16 sind noch eine Befestigungsfläche 68 für ein elektronisches Bauteil (z.B. Netzgerät), ein Anschlußflansch 69 für die Befestigung eines hier nicht gezeigten Geräteträgers und eine Steckverbindung 70 für die starre Verbindung der Rückwand 104 mit dem Gehäuseträger 9 dargestellt.FIG. 16 also shows a fastening surface 68 for an electronic component (e.g. power supply unit), a connecting flange 69 for fastening a device carrier (not shown here) and a plug connection 70 for the rigid connection of the rear wall 104 to the housing carrier 9.

Figur 18 zeigt den geschlossenen Eindruck der gesamten Gehäuserückseite. Aus Figur 19 geht noch hervor, in welcher Weise das erste Steckverbindungsteil 37 in die Ausnehmung 136 eingesetzt ist. Gewindebohrungen 71 dienen zum Einschrauben der in den Schraubkanälen 154 geführten Zugschrauben. Schraublöcher 72 dienen zum Einschrauben der Befestigungsschrauben für den Gehäuseträger 9. Die die Ausnehmung 136 umgebende Dichtfläche 148 dient zur Auflage der in der Dichtungsnut 149 gehaltenen Profildichtung.Figure 18 shows the closed impression of the entire back of the housing. FIG. 19 also shows how the first plug connection part 37 is inserted into the recess 136. Tapped holes 71 serve to screw in the tension screws guided in the screw channels 154. Screw holes 72 are used to screw in the fastening screws for the housing carrier 9. The sealing surface 148 surrounding the recess 136 serves to support the profile seal held in the sealing groove 149.

Um das Leitungsgehäuse 120 aus der in Figur 16 gezeigten Position nach unten abnehmen zu können, muß natürlich das gesamte Schutzgehäuse um das Lager 12 nach Lösen der Klemmverschraubung an der Neigeachse 15 um ein geringes Maß nach oben geschwenkt werden. Dies ist bei dem Ausführungsbeispiel nach den Figuren 1 bis 15 wegen der Zugänglichkeit der Anschlußstelle 11 von der Rückseite her nicht erforderlich. Bei entsprechender Schrägstellung des Schutzgehäuses ist es aber auch gegebenenfalls möglich, das Leitungsgehäuse 120 nach unten abzunehmen, ohne die Klemmverbindung im Bereich des Lagers 12 zu lösen.In order to be able to remove the cable housing 120 downward from the position shown in FIG. 16, the entire protective housing around the bearing 12 must of course be slightly moved after loosening the clamp screw connection on the tilt axis 15 Be pivoted upwards. In the exemplary embodiment according to FIGS. 1 to 15, this is not necessary because of the accessibility of the connection point 11 from the rear. With a corresponding inclination of the protective housing, it is also possible, if necessary, to remove the cable housing 120 downwards without loosening the clamp connection in the region of the bearing 12.
