Abstract

The invention is to provide a module for the connection of several participants by means of which, with a simple construction, a cable can be contacted simply, economically and reliably. To this end, a base housing (1) has a contacting device consisting essentially of a guide section (7), a conductor basket (9) and strip contact (6) with contact points (11). The conductor basket (9) can be secured at two heights in the guide section (7). With the conductor basket (9) in the upper preassembly position, the cable (5) with form coding can be fitted therein. When the conductor basket (9) is moved into the lower position, the insulation of the cable (5) is penetrated by the contact points (11) and at the same time conductor cores (3, 4) of the cable are contacted.

Description

Die Erfindung bezieht sich auf ein Modul zum Anschluß von Aktoren und/oder Sensoren, mit einem Gehäuse und mit einer in dem Gehäuse untergebrachten Kontaktierungseinrichtung zur Kontaktierung von Leitungsadern eines mehradrigen Kabels mit Kontakten, die mit einer elektrischen Schaltung des Moduls in Verbindung stehen.The invention relates to a module for connecting actuators and / or sensors, with a housing and with a contacting device accommodated in the housing for contacting line wires of a multi-core cable with contacts which are connected to an electrical circuit of the module.

Derartige Module sind von verschiedenen Herstellern, darunter vom Anmelder selbst auf den Markt. Die Module sind in Plug-in-Technik ausgeführt. Eine Weiterentwicklung dieser Module hat zu einem verbesserten Bus-Modul zum Anschluß mehrerer Teilnehmer (Aktoren, Sensoren) geführt, das aus einem den Anforderungen des Anwenders entsprechenden Oberteil als sogenanntes Anwendermodul und einem Unterteil zur Kontaktierung besteht. Da das Kabel als Busleitung verwendet wird, an die eine Vielzahl von Modulen angeschlossen werden sollen, ist die Ausführung des Moduls einschließlich seines Kontaktierungssystems von besonderer Bedeutung.Such modules are from various manufacturers, including the applicant himself on the market. The modules are designed using plug-in technology. A further development of these modules has led to an improved bus module for connecting several subscribers (actuators, sensors), which consists of an upper part corresponding to the requirements of the user as a so-called user module and a lower part for contacting. Since the cable is used as a bus line to which a large number of modules are to be connected, the design of the module including its contacting system is of particular importance.

Der Erfindung liegt die Aufgabe zugrunde, ein Modul zu schaffen, daß bei einfachem Aufbau die Kontaktierung des Kabels auf einfache Weise, kostengünstig und zuverlässig ermöglicht. Diese Aufgabe wird gelöst, gemäß den Merkmalen nach Patentanspruch 1. Eine vorteilhafte Weiterbildung des erfindungsgemäßen Gegenstandes besteht, wenn im Gehäuse eine Andruckfläche vorgesehen ist, die beim Schließen des Gehäuses den in der oberen Stellung verrasteten Leitungskorb zusammen mit dem eingelegten Kabel in die untere Stellung niederdrückt. Dies bedeutet, daß die Verschiebung des Leitungskorbes in die untere Stellung beim Schließen des Gehäuses selbsttätig erfolgt, wobei zugleich die Leitungsadern mit den Kontakten kontaktiert werden. Die Montage ist somit einfach und anwenderfreundlich.The invention has for its object to provide a module that allows contacting the cable in a simple manner, inexpensive and reliable with a simple structure. This object is achieved according to the features of claim 1. An advantageous further development of the subject matter according to the invention exists if a pressure surface is provided in the housing which, when the housing is closed, presses down the line basket which is locked in the upper position together with the inserted cable into the lower position . This means that the displacement of the cable basket into the lower position occurs automatically when the housing is closed, with the cable cores at the same time be contacted with the contacts. Installation is therefore simple and user-friendly.

Die erwähnte Verrastung des Leitungskorbes in zwei Höhenstellungen ist gemäß der folgenden Ausführungsform besonders einfach realisiert. Bei dieser weist das Führungsteil an seiner Innenseite zur Verrastung des Leitungskorbes in seinen beiden Stellungen in der Höhe und Länge versetzte erste Längsnuten und zweite Längsnuten auf. Der Leitungskorb ist an seiner Außenseite mit an die ersten und zweiten Längsnuten angepaßten ersten und zweiten Rastnasen versehen. In der oberen Stellung verrastet der Leitungskorb mit seinen ersten Rastnasen in den ersten Längsnuten. Diese Verrastung wird bei Verschiebung in die untere Stellung mit Klemmwirkung auf das Kabel aufgehoben. In der unteren Stellung verrastet der Leitungskorb mit seinen zweiten Rastnasen in den zweiten Längsnuten. Bei der beschriebenen Ausführungsform ergibt sich aufgrund der Klemmwirkung auf das Kabel in der unteren Stellung eine entsprechende Zugentlastung.The aforementioned locking of the cable basket in two height positions is realized in a particularly simple manner according to the following embodiment. In this case, the guide part has, on its inside, first longitudinal grooves and second longitudinal grooves offset in height and length in both positions for locking the cable basket. The outside of the cable basket is provided with first and second latching lugs adapted to the first and second longitudinal grooves. In the upper position, the cable basket latches with its first locking lugs in the first longitudinal grooves. This lock is released when moving to the lower position with a clamping effect on the cable. In the lower position, the cable basket with its second locking lugs locks in the second longitudinal grooves. In the described embodiment, due to the clamping effect on the cable in the lower position, there is a corresponding strain relief.

Gemäß einer weiteren vorteilhaften Ausbildung weist das Führungsteil in seiner Längsrichtung einen Mittelbereich und zwei diesem beidseitig angeschlossene Endbereiche auf. Im Mittelbereich sind die zweiten Längsnuten und die Kontaktspitzen und in den Endbereichen die ersten Längsnuten angeordnet. Der Leitungskorb hat entsprechende gegenüberliegende Teilbereiche. In seinem Mittelbereich sind die zweiten Rastnasen sowie die als Schnapphaken ausgeführten Positionierungsmittel und in seinen Endbereichen die ersten Rastnasen höhenversetzt angeordnet. Mittel- und Endbereiche des Leitungskorbes sind durch bis zum Korbboden reichende quer zur Längsachse gerichtete Schlitze voneinander getrennt. Durch diese Ausführungsform ist nicht nur gewährleistet, daß der Leitungskorb nicht aus seiner oberen Verrastung herausgehoben werden kann, sondern daß er auch in Längsrichtung arretiert ist, und damit unverlierbar mit dem Führungsteil verbunden ist.According to a further advantageous embodiment, the guide part has a central region in its longitudinal direction and two end regions connected to it on both sides. The second longitudinal grooves and the contact tips are arranged in the central region and the first longitudinal grooves in the end regions. The cable basket has corresponding opposite sections. The second locking lugs and the positioning means designed as snap hooks are arranged in its central region and the first locking lugs in its end regions are offset in height. The middle and end areas of the cable basket are separated from one another by slots extending transversely to the longitudinal axis and extending to the basket base. This embodiment not only ensures that the cable basket can not be lifted out of its upper catch, but that it also in Is locked in the longitudinal direction, and is thus captively connected to the guide part.

Weiterhin ist es vorteilhaft, wenn die Kontaktierung zwischen den Leitungsadern und den Kontakten durch Verbindung eines Oberteil-Gehäuses mit dem Unterteil-Gehäuse erfolgt, und wenn dabei eine druckstempelförmige Ausbuchtung einer unterseitigen Abdeckung des Oberteil-Gehäuses als Andruckfläche wirksam ist. Die ohnehin erforderliche Abdeckung wird hier zusätzlich zum Andruck des Leitungskorbes mit dem Kabel verwendet.Furthermore, it is advantageous if the contacting between the line wires and the contacts takes place by connecting an upper part housing to the lower part housing, and if a bulge-shaped bulge of an underside cover of the upper part housing is effective as a pressure surface. The cover required anyway is used here in addition to pressing the cable basket with the cable.

Um sicherzustellen, daß beim Zusammenbau des Oberteil-Gehäuses mit dem Unterteil-Gehäuse diese lagerichtig aufeinander sitzen, ist es vorteilhaft, wenn an der Abdeckung unterschiedlich ausgebildete Kodiernasen vorgesehen sind, die in entsprechende Führungen des Unterteil-Gehäuses hineinpassen. Es ist weiterhin vorteilhaft, wenn zum Anschluß der Aktoren und/oder Sensoren Steck-Schraubanschlüsse in dem Oberteil-Gehäuse derart verteilt vorgesehen und hierzu gehörige Steckergewinde eingeformt sind, daß gerade und abgewinkelte Stecker angeschlossen werden können, und wenn neben den Steckergewinden Schilder-Ausnehmungen für einschnappbare Bezeichnungsschilder vorhanden sind, die in eindeutiger Zuordnung zu den Steck-Schraubanschlüssen stehen. Hier lassen sich mehrere Stecker auf engem Raum ohne gegenseitige Behinderung anschließen, wobei zugleich zu jedem Stecker-Anschluß ein Bezeichnungsschild mit eindeutiger Zuordnung zu dem jeweiligen Stecker-Schraubanschluß besteht.In order to ensure that when the upper part housing is assembled with the lower part housing, they sit on one another in the correct position, it is advantageous if differently designed coding lugs are provided on the cover, which fit into corresponding guides of the lower part housing. It is furthermore advantageous if plug-in screw connections are provided in the upper part housing in such a distributed manner for the connection of the actuators and / or sensors, and associated plug threads are formed in such a way that straight and angled plugs can be connected, and if, in addition to the plug threads, shield recesses for snap-on labels are available that are clearly assigned to the plug-in screw connections. Here, several plugs can be connected in a confined space without mutual hindrance, and at the same time there is a label for each plug connection with a clear assignment to the respective plug screw connection.

Um ein versehentliches Anschließen von Aktoren und Sensoren an dafür nicht vorgesehene Steck-Schraubanschlüsse zu vermeiden, sind diese unterschiedlich kodiert.To prevent accidental connection of actuators and sensors to plug-in screw connections that are not intended for this purpose, they are coded differently.

Eine weitere vorteilhafte Weiterbildung der Erfindung besteht gemäß den Ansprüchen 12 und 13. Diese ermöglicht, das Modul auch als elektrische Verzweigung zu verwenden, indem man ein zweiadriges Kabel im Modul stumpf enden läßt und das zweite Kabel hindurchführt.A further advantageous development of the invention exists according to claims 12 and 13. This enables the Module can also be used as an electrical junction by allowing a two-core cable to have a blunt end in the module and passing the second cable through.

To accommodate the two form-coded flat cables 5, correspondingly form-coded housing recesses 27 are provided on the side of the lower part housing 1, into which profile seals 21 are inserted at the bottom as kink protection for the flat cables 5.

Wird im Modul nur ein Flachkabel 5 kontaktiert (siehe FIG 1), so werden die nicht verwendeten Gehäuse-Ausnehmungen 27 mit Füllstücken 29 versehen.If only a flat cable 5 is contacted in the module (see FIG. 1), the unused housing recesses 27 are provided with filler pieces 29.

On each long side of the rectangular front of the upper part housing 2, two plug-in screw connections 25 are provided at a sufficient distance from one another, the one long side being offset from those of the other long side. In addition, 25 identification plates 28 are arranged in trapezoidal plate recesses 36 in clear association with the plug-in screw connections, and numerical identification is additionally provided.

Die als Steck-Schraubanschlüsse ausgeführten vier Teilnehmerabgänge 25 sind so angeordnet, daß gerade und abgewinkelte Stecker 35 mit angespritzten Leitungen, wie auch Stecker mit frei zugänglichen Anschlußklemmen angeschlossen werden können. Die Steckergewinde 26 (hier nicht sichtbar, siehe FIG 2,4) zu den Steck-schraubanschlüssen 25 sind in das Oberteil-Gehäuse 2 eingeformt. Nicht verwendete Teilnehmer-Anschlüsse 25 sind durch Schraubkappen 31 abdeckbar.The four subscriber outlets 25 designed as plug-in screw connections are arranged in such a way that straight and angled plugs 35 with molded lines, as well as plugs with freely accessible connecting terminals, can be connected. The plug threads 26 (not visible here, see FIG. 2.4) for the plug-in screw connections 25 are molded into the upper part housing 2. Unused subscriber connections 25 can be covered by screw caps 31.

Neben den vier Bezeichnungsschildern 28 für die Teilnehmer-Anschlüsse 25 ist mittig ein weiteres durch die Aufschrift "Bus" gekennzeichnetes Bezeichnungsschild 28 angebracht. Auch hier ist die Zuordnung zum hier als Bus bezeichneten Flachkabel 5 eindeutig. Bohrungen 32 neben den Bezeichnungsschildern 28 dienen zur optischen Anzeige des Betriebszustands der betreffenden Komponenten 25,5.In addition to the four identification plates 28 for the subscriber connections 25, a further identification plate 28 identified by the inscription "bus" is attached in the center. Here too, the assignment to the flat cable 5, referred to here as the bus, is clear. Bores 32 next to the identification plates 28 serve to visually display the operating state of the relevant components 25, 5.

FIG 2 zeigt eine Explosionsdarstellung des Moduls, dessen Komponenten gemäß der Darstellung von oben nach unten vorgestellt werden. Zur Verbindung der Komponenten miteinander wird auf die FIG 3,4 verwiesen.2 shows an exploded view of the module, the components of which are presented from top to bottom as shown will. For the connection of the components to one another, reference is made to FIG. 3.4.

Zum Oberteil-Gehäuse 2 mit den frontseitig angeordneten vier Steck-Schraubanschlüssen 25 und Schilder-Ausnehmungen 36 gehören unverlierbar eingedrehte Gehäuseschrauben 37 zur Verschraubung mit dem Unterteil-Gehäuse 1. Die Dichtheit der Steck-Schraubanschlüsse 25 wird über O-Ringe 38 am Boden der Steckergewinde 26 erreicht und erfaßt mit dem Stecker 35 (siehe FIG 1) den gesamten Steckerraum. Den Bohrungen 32 im Oberteil-Gehäuse 2 schließen sich Aussparungen 39 an, die zur Aufnahme von Lichtleitern 40 mit dazugehörigen Gummidichtungen 41 dienen. Die Lichtleiter 40 übertragen das Licht von zu elektrischen Schaltung 8 gehörigen Leuchtdioden 44 (siehe FIG 3) an die Oberfläche des Oberteil-Gehäuses 2. Jeder Teilnehmerabgang 25 hat eine gelbe und, zur Unterscheidung hiervon, die aktivierte Busleitung 5 eine grüne Anzeige. Die Lichtleiter 40 sind mit einem Bund in das Oberteil-Gehäuse 2 eingelassen und können von Hand nicht tiefer eingedrückt werden. Eine Wulst am Schaft des Lichtleiters 40 schnappt hinter die Gummidichtung 41 und verhindert das Herauswandern des Lichtleiters 40 aus dem Oberteil-Gehäuse 2 in Gegenrichtung.The upper part housing 2 with the four plug-in screw connections 25 and plate recesses 36 arranged on the front include captive screwed-in housing screws 37 for screwing to the lower part housing 1. The tightness of the plug-in screw connections 25 is established via O-rings 38 on the bottom of the plug thread 26 reaches and detects the entire connector space with the connector 35 (see FIG. 1). The bores 32 in the upper part housing 2 are followed by cutouts 39 which serve to receive light guides 40 with associated rubber seals 41. The light guides 40 transmit the light from light-emitting diodes 44 belonging to electrical circuit 8 (see FIG. 3) to the surface of the upper part housing 2. Each subscriber outlet 25 has a yellow and, to distinguish it, the activated bus line 5 a green display. The light guides 40 are embedded in the upper part housing 2 with a collar and cannot be pressed in deeper by hand. A bead on the shaft of the light guide 40 snaps behind the rubber seal 41 and prevents the light guide 40 from migrating out of the upper part housing 2 in the opposite direction.

Die oben erwähnte elektrische Schaltung 8 ist im wesentlichen auf einer Leiterplatte 42 realisiert, in die zwei abgesetzte Kontaktstifte 43 eingelötet sind, die einerseits im Oberteil-Gehäuse 2 festklemmen und andererseits in die Kontakte 6 des Unterteil-Gehäuses 1 eintauchen und damit das Potential der Busleitung 5 an die Leiterplatte 42 bringen. Diese ist mit den Leuchtdioden 44, mit Relais 45, die platzsparend am Rand angeordnet sind, sowie mit SMD-Bauteilen 46 bestückt (siehe FIG 4). Die Leiterplatte 42 wird von einer Abdeckung 22 gehalten, die unterseitig in das Oberteil-Gehäuse 2 eingedrückt ist und sich über die Leiterplatte 42 an denen Steckerdomen 30 der Teilnehmeranschlüsse 25 abstützt. Die Befestigung erfolgt mit zwei Blechschrauben 47. Die Abstützung an den Steckerdomen 30 ist platzsparend und ermöglicht eine optimale Ausnützung der Leiterplatte 42 hinsichtlich Bestückungsfläche. Die vier Abstützpunkte durch die Steckerdome 30 nehmen auch die Kräfte auf das Oberteil-Gehäuse 2 auf, die sich ergeben, wenn die Busleitungen 5 in die Kontakte 6 des Moduls eingedrückt werden.The above-mentioned electrical circuit 8 is essentially realized on a printed circuit board 42, into which two remote contact pins 43 are soldered, which on the one hand clamp in the upper part housing 2 and on the other hand dip into the contacts 6 of the lower part housing 1 and thus the potential of the bus line 5 bring to the circuit board 42. This is equipped with the light-emitting diodes 44, with relays 45, which are arranged on the edge to save space, and with SMD components 46 (see FIG. 4). The printed circuit board 42 is held by a cover 22 which is pressed into the upper part housing 2 on the underside and is supported via the printed circuit board 42 on which plug domes 30 of the subscriber connections 25 are supported. It is fastened with two self-tapping screws 47. The support on the plug domes 30 is space-saving and enables optimum utilization of the printed circuit board 42 with regard to the assembly area. The four support points through the plug domes 30 also absorb the forces on the upper part housing 2 which result when the bus lines 5 are pressed into the contacts 6 of the module.

Die Abdeckung 22 erfüllt mehrere Aufgaben. Sie deckt die Leiterplatte 42 gegen manuelles Berühren ab, sie überträgt die Kontaktierungskräfte, und sie nimmt die Oberteil-Dichtung 33 auf und fixiert sie durch die vier Steckerdome 30. Zudem gewährleistet die Abdeckung 22 das lagerichtige Aufsetzen des Oberteil-Gehäuse 2 auf das Unterteil-Gehäuse 1. Hierzu sind an beiden Enden der Abdeckung 22 unterschiedliche Kodiernasen 48 vorhanden, welche in entsprechende Führungen 24 des Unterteil-Gehäuses 1 hineinpassen (siehe FIG 6).The cover 22 serves several purposes. It covers the circuit board 42 against manual contact, it transmits the contacting forces, and it picks up the upper part seal 33 and fixes it by means of the four plug domes 30. In addition, the cover 22 ensures that the upper part housing 2 is placed in the correct position on the lower part. Housing 1. For this purpose, different coding lugs 48 are provided on both ends of the cover 22, which fit into corresponding guides 24 of the lower part housing 1 (see FIG. 6).

Der Abstand zwischen der Abdeckung 22 und der Leiterplatte 42 ist an die bei SMD-Bauteilen übliche maximale Höhe angepaßt.The distance between the cover 22 and the circuit board 42 is adapted to the maximum height customary in SMD components.

Am Oberteil-Gehäuse 2 ist die Oberteil-Dichtung 33 eingelegt, die von Domen der Abdeckung 22 gehalten ist.On the upper part housing 2, the upper part seal 33 is inserted, which is held by domes of the cover 22.

Die Busleitungen 5 mit zwei Leitungsadern 3,4 zum Anschluß an unterschiedliche Polaritäten werden mittels der Kontaktierungseinrichtung mit den Kontakten 6 kontaktiert. Zur Kontaktierungseinrichtung gehören in einem Führungsteil 7 (siehe FIG 3,4,5) verrastbare Leitungskörbe 9. Das Führungsteil 7 liegt mittig am Boden des Unterteil-Gehäuses 1. Zur Aufnahme der Busleitungen 5 sind am oberen Rand der Längsseiten des Unterteil-Gehäuses 1 die bereits erwähnten profilierten Gehäuse-Ausnehmungen 27 eingebracht, in die die Profil-Dichtungen 21 vor dem Einlegen der Busleitungen 5 eingesetzt werden. Die Verschraubung mit dem Oberteil-Gehäuse 2 erfolgt über die Gehäuse-Schrauben 37 mit dazu passenden Gewindebuchsen 52 im Unterteil-Gehäuse 1.The bus lines 5 with two line wires 3, 4 for connection to different polarities are contacted with the contacts 6 by means of the contacting device. The contacting device includes, in a guide part 7 (see FIGS. 3, 4, 5), snap-in line baskets 9. The guide part 7 is located centrally on the bottom of the lower part housing 1 already mentioned profiled housing recesses 27 are introduced into which the profile seals 21 are inserted before the bus lines 5 are inserted. The screw connection with the upper part housing 2 takes place via the housing screws 37 with matching threaded bushings 52 in the lower part housing 1.

In FIG 3 ist die im wesentlichen aus dem Führungsteil 7, den Kontakten 6 und Leitungskörben 9 bestehende Kontaktierungseinrichtung dargestellt. Das Führungsteil 7 weist zwei kanalförmige Ausnehmungen auf, in denen je ein Leitungskorb 9 in einer oberen und einer unteren Stellung verrastbar ist.FIG. 3 shows the contacting device consisting essentially of the guide part 7, the contacts 6 and the cable baskets 9. The guide part 7 has two channel-shaped recesses, in each of which a cable basket 9 can be locked in an upper and a lower position.

Die Kontakte 6 sind aus einem Band ausgestanzt und gebogen. In ihr eines, gabelförmig ausgebildete Ende tauchen die Kontaktstifte 43 bei der Montage des Moduls und bringen das Potential der Busleitung 5 an die Leiterplatte 42. In der Mitte und am Ende der Kontakte 6 sind Kontaktspitzen 11 zur Kontaktierung der beiden Busleitungen 5 angeordnet. Die Kontakte 6 sind mit ihren Kontaktspitzen 11 zur Kanalöffnung gerichtet, mittig am Boden der beiden kanalförmigen Ausnehmungen des Führungsteils 7 gehalten.The contacts 6 are punched out of a band and bent. In it, a fork-shaped end, the contact pins 43 dip during assembly of the module and bring the potential of the bus line 5 to the circuit board 42. In the middle and at the end of the contacts 6, contact tips 11 are arranged for contacting the two bus lines 5. The contacts 6 are directed with their contact tips 11 to the channel opening, held in the center at the bottom of the two channel-shaped recesses of the guide part 7.

Das Führungsteil 7 weist an seiner Innenseite zur Verrastung des Leitungskorbes 9 in den beiden Stellungen in der Höhe und Länge versetzte erste 14 im Mittelbereich und zweite 15 in den Endbereichen angeordnete Längsnuten auf. An der einen Innenseite ist jede kanalförmige Ausnehmung mit einem quer zur Längsachse liegenden Steg 20 versehen.The guide part 7 has on its inside for locking the line cage 9 in the two positions in height and length offset first 14 in the central region and second 15 longitudinal grooves arranged in the end regions. On one inner side, each channel-shaped recess is provided with a web 20 lying transversely to the longitudinal axis.

Der Leitungskorb 9 hat ein der formkodierten Busleitung 5 angepaßtes Innenprofil, so daß eine hier hineingelegte Busleitung 5 formschlüssig umfaßt wird. An den Außenseiten des Leitungskorbes 9 sind an die ersten 14 und zweiten Längsnuten 15 angepaßte erste 16 und zweite Rastnasen 17 entsprechend angeordnet. Beim Einlegen des Leitungskorbes 9 in das Führungsteil 7 kommt es zu einer Verrastung zwischen den ersten Längsnuten 14 und den ersten Rastnasen 16 in einer oberen Vormontage-Stellung. In dieser Position wird die Busleitung 5 in den Leitungskorb 9 eingelegt und dabei durch nach innen ragende Schnapphaken 13 gehalten. Durch weiteren Andruck ist der Leitungskorb 9 in die untere Stellung verschiebbar, in der die zweiten Rastnasen 17 in den zweiten Längsnuten 15 verrasten und in der die Kontaktspitzen 11 durch bodenseitige Schlitze 10 ragen. Dies bedeutet, daß die Kontaktspitzen 11 bei der Absenkung des Leitungskorbes 9 zusammen mit der Busleitung 5 deren Isolierung durchstoßen und sich in die als Litzen ausgeführten Leitungsadern 3,4 hineinbohren.The cable basket 9 has an inner profile adapted to the form-coded bus line 5, so that a bus line 5 inserted here is positively embraced. First 16 and second locking lugs 17, which are matched to the first 14 and second longitudinal grooves 15, are correspondingly arranged on the outer sides of the line cage 9. When the cable basket 9 is inserted into the guide part 7, there is a latching between the first longitudinal grooves 14 and the first latching lugs 16 in an upper preassembly position. In this position, the bus line 5 is inserted into the line basket 9 and in the process held by inwardly projecting snap hooks 13. By further pressure, the cable basket 9 can be moved into the lower position, in which the second latching lugs 17 engage in the second longitudinal grooves 15 and in which the contact tips 11 protrude through slots 10 on the bottom. This means that when the cable basket 9 is lowered, the contact tips 11, together with the bus line 5, penetrate the insulation thereof and drill into the line wires 3, 4 designed as strands.

Die im Führungsteil 7 innenseitig liegenden Stege 20 schieben sich in die Schlitze 19 des Leitungskorbes 9, die bis zu dessen Boden 18 reichen und die den Leitungskorb 9 längsseits ebenfalls in einen Mittelbereich und zwei Endbereiche mit den dortliegenden ersten 16 und zweiten Rastnasen 17 unterteilen. Über im Mittelbereich angeformten Lippen 53 kann die Verrastung in der unteren Stellung des Leitungskorbes 9 mittels Schraubendreher aufgehoben werden, was eine Verschiebung in die obere Stellung ermöglicht. Eine Längsverschiebung des Leitungskorbes 9 ist jedoch durch Eingriff der Stege 20 des Führungsteils 7 in die Schlitze 19 des Leitungskorbs 9 ausgeschlossen.The webs 20 located on the inside in the guide part 7 slide into the slots 19 of the cable basket 9, which extend to the bottom 18 thereof and also divide the cable basket 9 along the sides into a central region and two end regions with the first 16 and second locking lugs 17 located there. The lips in the lower position of the cable basket 9 can be released by means of a screwdriver via lips 53 formed in the middle area, which enables a displacement into the upper position. A longitudinal displacement of the cable basket 9 is excluded by engagement of the webs 20 of the guide part 7 in the slots 19 of the cable basket 9.

FIG 4 zeigt einen Längsschnitt durch das erfindungsgemäße Modul, dessen Aufbau bereits weitgehend in den vorangegangenen Figurenbeschreibungen (FIG 1, 2, 3) erklärt wurde. An dieser Stelle wird daher nur auf das Kontaktierungssystem eingegangen. Hierzu verdeutlicht FIG 4 die Lage des Leitungskorbes 9 und sein Zusammenwirken mit kontaktierten Busleitungen 5. Der hier dargestellte Schnitt durch die linke Busleitung 5 ist auf den Mittelbereich des Führungsteils 7 und des Leitungskorbes 9 bezogen. Die zweiten Rastnasen 17 rasten hier in die tiefgelegenen zweiten Längsnuten 15 ein, und der Leitungskorb 9 umschließt die formkodierte Busleitung 5 mit ihren Schnapphaken 13. Die unter dem Leitungskorb 9 angeordneten Kontakte 6 durchstoßen mit ihren Kontaktspitzen 11 die Isolierung der Busleitung 5 und durchdringen die Litzen 3,4. Die druckstempelförmige Ausbuchtung 12 der Abdeckung 22 dient als auf die Busleitung 5 oberseitig wirkende Andruckfläche. Nach Abnehmen des Oberteil-Gehäuses 2 mit der Abdeckung 22 verbleiben Leitungskorb 9 und Busleitung 5 in der dargestellten Stellung. Mit einem Schraubendreher läßt sich der Leitungskorb über seine oben angeformten Lippen 53 entrasten. Die Busleitung 5 auf der rechten Seite ist im Schnitt durch einen der Endbereichre des Führungsteils 7 und des Leitungskorbs 9 gezeigt. Hier sind die ersten Längsnuten 14 angeordnet, die gegenüber den im Mittelbereich liegenden zweiten Längsnuten 15 höher liegen. Die Busleitung 5 liegt hier wie im Mittelbereich ebenfalls formschlüssig im Leitungskorb 9. Dessen äußere erste Rastnasen 16 sind nicht verrastet, sondern liegen innen an dem Führungsteil 7 an und drücken damit den Endbereich des Leitungskorbes 9 mit der Busleitung 5 zusammen. Auf diese drückt auch hier die druckstempelförmige Ausbuchtung 12 der Abdeckung 22. Mit diesen Maßnahmen ergibt sich die gewünschte Zugentlastung der Busleitung 5.4 shows a longitudinal section through the module according to the invention, the structure of which has already been largely explained in the preceding figure descriptions (FIGS. 1, 2, 3). At this point, therefore, only the contacting system is discussed. 4 clarifies the position of the cable basket 9 and its interaction with contacted bus lines 5. The section shown here through the left bus line 5 relates to the central region of the guide part 7 and the cable basket 9. The second locking lugs 17 snap into the deep-lying second longitudinal grooves 15, and the cable basket 9 encloses the form-coded bus line 5 with its snap hooks 13. The contacts 6 arranged under the cable basket 9 pierce with their contact tips 11 the insulation of the bus line 5 and penetrate the strands 3,4. The pressure stamp-shaped bulge 12 of the cover 22 serves as a pressure surface acting on the top of the bus line 5. After removing the upper part housing 2 with the cover 22, the cable basket 9 and bus cable 5 remain in the position shown. With a screwdriver, the cable basket can be unlatched via its lips 53 formed above. The bus line 5 on the right-hand side is shown in section through one of the end regions of the guide part 7 and the line basket 9. Here, the first longitudinal grooves 14 are arranged, which are higher than the second longitudinal grooves 15 lying in the central region. As in the central area, the bus line 5 also lies in a form-fitting manner in the line basket 9. Its outer first latching lugs 16 are not locked, but lie against the inside of the guide part 7 and thus press the end region of the line basket 9 together with the bus line 5. The bulge 12 of the cover 22, which is in the form of a pressure pad, also presses on this here. These measures result in the desired strain relief for the bus line 5.

Die FIG 5 zeigt insbesondere die Kontaktierungseinrichtung des Moduls im Querschnitt. Der bodenseitig im Unterteil-Gehäuse 1 angeordnete Kontakt 6 durchstößt mit seinen beiden Kontaktspitzen 11 die Isolierung der im Leitungskorb eingelegten Busleitung 5, die von der druckstempelförmigen Ausbuchtung 12 der Abdeckung 22 in die untere Stellung verrastend niedergedrückt und dort gehalten ist. An den Seiten hat das Unterteil-Gehäuse 1 die Gehäuse-Ausnehmungen 27, in die Profildichtungen 21 als Unterlage für die Busleitung 5 eingesetzt sind.5 shows in particular the contacting device of the module in cross section. The contact 6 arranged at the bottom in the lower part housing 1 pierces with its two contact tips 11 the insulation of the bus line 5 inserted in the line basket, which is pressed down by the pressure-stamped bulge 12 of the cover 22 into the lower position and held there. On the sides, the lower part housing 1 has the housing recesses 27, into which profile seals 21 are inserted as a base for the bus line 5.

FIG 6 zeigt eine Draufsicht auf das Unterteil-Gehäuse 1 mit einer im linken Führungsteil 7 mit dem Leitungskorb 9 eingelegten stumpf endenden Busleitung 5. Über diese allein ist die Versorgung der elektrischen Schaltung 8 und die Kommunikation mit den anzuschließenden Teilnehmern möglich. Grundsätzlich besteht jedoch der Bedarf mehrere Module an die Busleitung 5 anzuschließen, wozu die Busleitung 5 wird durch die Module hindurchgeführt wird. Aus Redundanzgründen ist es zweckmäßig zwei Busleitungen 5 vorzusehen. Beide sind über die Kontakte 6 mit ihren Kontaktspitzen 11 im kontaktierten Zustand polaritätsmäßig elektrisch durchverbunden. Somit ergibt sich die Möglichkeit, die Module auch als elektrische Verzweigungen mit einer stumpf endenden und mit einer durchgehenden Busleitung im Modul zu verwenden.6 shows a plan view of the lower part housing 1 with a butt-terminating bus line 5 inserted in the left guide part 7 with the cable basket 9. This alone enables the electrical circuit 8 to be supplied and communication with the subscribers to be connected. Basically, however, there is a need for several modules to connect the bus line 5, for which purpose the bus line 5 is passed through the modules. For reasons of redundancy, it is advisable to provide two bus lines 5. Both are electrically connected in terms of polarity via the contacts 6 with their contact tips 11 in the contacted state. This makes it possible to use the modules as electrical branches with a butt-terminating and with a continuous bus line in the module.

Neben dem Führungsteil 7 sind im Unterteil-Gehäuse 1 drei Taschen 51 vorhanden, in denen nicht verwendete Füllstücke 29 und Profildichtungen 21 abgelegt werden können.In addition to the guide part 7, three pockets 51 are present in the lower part housing 1, in which filler pieces 29 and profile seals 21 that are not used can be stored.

Passend zu den unterschiedlich gestalteten Kodiernasen 48 in der Abdeckung 22 (siehe FIG 2) des Oberteil-Gehäuses 2 befinden sich die in FIG 6 sichtbaren Führungen 24 im Unterteil-Gehäuse 1. Damit wird das lagerichtige Zusammensetzen des Gehäuses 1,2 auf einfache Weise gewährleistet.Matching the differently designed coding lugs 48 in the cover 22 (see FIG. 2) of the upper part housing 2, the guides 24 visible in FIG. 6 are located in the lower part housing 1. This ensures that the housing 1, 2 is assembled in a simple manner .
