- automatic fire detectors are designed in two parts, with the detector holder permanently installed on the ceiling, into which a removable detector part can be inserted.
- the detector part itself consists of a printed circuit board with the necessary electronic components and the actual detector system as well as a detector cap that covers the whole.
- a maximum of three, generally uniformly distributed sliding contacts were provided for the electrical connection, to which the wiring was clamped.
- the detector insert had correspondingly arranged contacts, which also took over the mechanical locking when the detector was turned when it was inserted. In order to ensure a good locking, an even distribution of the contacts on the circumference was necessary.
- Such detectors required complex contact both in the detection and in the detector use.
- the wiring was cumbersome, especially when three electrical connections were necessary.
- the object of the invention is to create a new electrical connection between the socket and the detector, where it is possible to connect several supply wires as well as shield connections with a simple assembly effort.

Abstract
Description
Die Erfindung bezieht sich auf einen automatischen Brandmelder mit einer Melderfassung und einem Meldereinsatz, der eine Leiterplatte mit Baugruppe und ein Sensorsystem aufweist sowie mit einer Melderkappe.The invention relates to an automatic fire detector with a detector detection and a detector insert, which has a printed circuit board with an assembly and a sensor system, and with a detector cap.
In der Regel sind automatische Brandmelder zweiteilig ausgebildet, dabei ist die Melderfassung fest an der Decke installiert, in die ein abnehmbares Melderteil eingesetzt werden kann. Das Melderteil selbst besteht dabei aus einer Leiterplatte mit den erforderlichen elektronischen Bauteilen und dem eigentlichen Meldersystem sowie einer Melderkappe, die das Ganze abdeckt. Für den elektrischen Anschluß waren bisher beispielsweise max.drei, im allgemeinen gleichförmig auf dem Kreisrand der Melderfassung verteilt Gleitkontakte vorgesehen, an die die Verdrahtung angeklemmt wurde. Der Meldereinsatz wies entsprechend angeordnete Kontakte auf, die durch das Drehen des Melders beim Einsetzen auch gleichzeitig die mechanische Verriegelung übernahmen. Um eine gute Verriegelung zu gewährleisten, war eine gleichmäßige Verteilung der Kontakte am Umfang erforderlich. Derartige Melder erforderten aufwendige Kontakt sowohl in der Melderfassung als auch im Meldereinsatz. Zudem war die Verdrahtung umständlich, insbesondere dann, wenn drei elektrische Verbindungen notwendig waren.As a rule, automatic fire detectors are designed in two parts, with the detector holder permanently installed on the ceiling, into which a removable detector part can be inserted. The detector part itself consists of a printed circuit board with the necessary electronic components and the actual detector system as well as a detector cap that covers the whole. Up to now, for example, a maximum of three, generally uniformly distributed sliding contacts were provided for the electrical connection, to which the wiring was clamped. The detector insert had correspondingly arranged contacts, which also took over the mechanical locking when the detector was turned when it was inserted. In order to ensure a good locking, an even distribution of the contacts on the circumference was necessary. Such detectors required complex contact both in the detection and in the detector use. In addition, the wiring was cumbersome, especially when three electrical connections were necessary.
Aufgabe der Erfindung ist es, eine neue elektrische Verbindung zwischen der Fassung und dem Melder zu schaffen, bei der es möglich ist, mehrere Zuleitungsadern sowie Schirmungsanschlüsse mit einem einfachen Montageaufwand anzuschließen. Ferner soll das Einsetzen des Melders durch gutes Zentrieren einfach und sicher möglich sein, auch unter erschwerten Bedingungen, z.B. wenn der Meldereinsatz mit einem sogenannten Pflücker abgenommen oder eingesetzt werden soll.The object of the invention is to create a new electrical connection between the socket and the detector, where it is possible to connect several supply wires as well as shield connections with a simple assembly effort. Furthermore, it should be possible to insert the detector simply and safely by good centering, even under difficult conditions, for example if the detector insert is to be removed or used with a so-called picker.
Diese Aufgabe wird erfindungsgemäß bei einem eingangs beschriebenen automatischen Brandmelder mit den kennzeichnenden Merkmalen des Anspruchs 1 gelöst.This object is achieved according to the invention in an automatic fire detector described at the outset with the characterizing features of
In der Melderfassung, die aus einem einfachen Spritzteil bestehen kann, ist ein mehrpoliger Anschlußblock mit den erforderlichen Steckbuchsen beispielsweise einrastbar angeordnet. Der Meldereinsatz weist eine Kontaktstiftleiste mit den entsprechenden Kontaktsstiften auf, die dem Anschlußblock beim Einsetzen des Melders zwangsweise zugeordnet werden. Daher ist der Meldereinsatz drehbar in der umlaufenden Melderkappe angeordnet und in seiner Endlage arretierbar. Zu diesem Zweck weist der Meldereinsatz eine umlaufende Seitenwand auf, die als Zentrierungsring fungiert. Die Melderkappe ist auf der Melderfassung mechanisch verriegelbar, wobei beim Einsetzen des Melders, d.h. Sensorsystem mit Meldereinsatz und Melderkappe, eine an der Melderkappe angeformte Verriegelungsnocke in einer schräg verlaufenden Kulissenführung einer Verriegelungskulisse geführt ist. Die Verriegelungskulisse ist an der Melderfassung derart angeordnet, daß ein vertikaler Hub für die Kontaktierung erreicht wird, wenn der Melder eingesetzt und eingedreht wird.In the detector, which can consist of a simple molded part, a multi-pole connection block with the necessary sockets is arranged, for example, snap. The detector insert has a contact pin strip with the corresponding contact pins, which are forcibly assigned to the terminal block when the detector is inserted. The detector insert is therefore rotatably arranged in the circumferential detector cap and can be locked in its end position. For this purpose, the detector insert has a peripheral side wall that acts as a centering ring. The detector cap can be mechanically locked on the detector holder, and when the detector, ie sensor system with detector insert and detector cap, is inserted, a locking cam formed on the detector cap is guided in an oblique sliding guide of a locking link. The locking link is arranged on the detector socket in such a way that a vertical stroke for contacting is achieved when the detector is inserted and screwed in.
Mit der erfindungsgemäßen Ausgestaltung des Brandmelders ist eine sichere und zuverlässige elektrische Kontaktgabe und mechanische Verriegelung zwischen dem eigentlichen Melderteil und der Melderfassung gewährleistet, wobei beim Einsetzen eine eindeutige Zuordnung zwischen den Kontaktstiften des Melderteils und den Kontaktbuchsen in der Melderfassung erfolgt. Die über den Meldereinsatz und die Fassung hinübergezogene Melderkappe deckt dabei gleichzeitig die Melderfassung ab, so daß beispielsweise bei einem Meldertausch nicht mehr wie früher sich dann die verschmutzte Fassung deutlich von der neuen sauberen Melderkappe abhebt.With the design of the fire detector according to the invention, a safe and reliable electrical contact and mechanical locking between the actual detector part and the detector detection is guaranteed, with a clear assignment between the contact pins of the detector part and the contact sockets in the detector detection when inserted. The detector cap pulled over the detector insert and the holder simultaneously covers the detector holder, so that, for example, when a detector is replaced, the dirty holder does not stand out clearly from the new, clean detector cap.
Die Arretiervorrichtung zwischen Melderkappe und Meldereinsatz kann von einer Feder gebildet sein, die an der Melderkappe angeordnet ist und am Meldereinsatz in einem dafür vorgesehenen Rastnut verrastbar ist.The locking device between the detector cap and detector insert can be formed by a spring which is arranged on the detector cap and can be latched on the detector insert in a latching groove provided for this purpose.
In einer vorteilhaften Ausgestaltung der Erfindung ist der Anschlußblock exzentrisch in der Melderfassung angeordnet, wobei die Melderfassung einen hinreichend großen Schlaufenraum für eine günstige Montage der Anschlußdrähte schafft. Außerdem kann in vorteilhafter Weise der austauschbare Klemmenblock in unterschiedlicher Anschlußtechnik, z.B. mit Schraub- oder Federkraft, oder Schneidklemmen ausgeführt sein. Eine interne Verdrahtung der Anschlußklemmen ermöglicht in gleichbleibender Reihenfolge ein übersichtliches Auflegen der Anschlußdrähte.In an advantageous embodiment of the invention, the connection block is arranged eccentrically in the detector socket, the detector socket creating a sufficiently large loop space for inexpensive installation of the connection wires. In addition, the interchangeable terminal block can be advantageously used in different connection technology, e.g. be carried out with screw or spring force, or insulation displacement terminals. Internal wiring of the connection terminals enables the connection wires to be clearly laid out in the same order.
Um eine durchgeschleifte Ader beim Einsetzen des Melders unterbrechen zu können, weist der Anschlußblock mindestens einen Schaltkontakt (Unterbrecherkontakt) auf, der von einem Betätigungselement, z.B. Betätigungsstift, der Kontaktstiftleiste oder des Meldereinsatzes betätigt werden kann.In order to be able to interrupt a looped wire when inserting the detector, the connection block has at least one switching contact (interrupter contact) which can be actuated by an actuating element, for example actuating pin, the contact pin strip or the detector insert.

Es wurde wie bisher die Zweiteilung zwischen Melderfassung und eigentlichem Melder beibehalten. Die Melderfassung 1 besteht lediglich aus einem einfachen Spritzteil, in dem der Anschlußblock 2 eingerastet wird. Im Anschlußblock 2 sind die erforderlichen Steckbuchsen 2a, Leitungsanschlüsse (a,b,...) und der Unterbrecherkontakt 2b zusammengefaßt.
Durch die exzentrische Anordnung des Klemmenblockes 2 im Spritzteil der Melderfassung 1 wird ein möglichst großer Schlaufenraum 3 für eine bequeme Montage der Anschlußdrähte geschaffen. Eine interne Verdrahtung der Anschlußklemmen ermöglicht eine gleichbleibende Reihenfolge bei der Verdrahtung und somit ein übersichtliches Auflegen der Anschlußdrähte, wie dies in Fig.4 schematisch dargestellt ist. Dabei bedeutet ML die Meldeleitung, beispielsweise zwei Adern a und b, die geschirmt (S) ist. In der Melderfassung 1 ist der Anschlußblock 2 mit den Kontaktbuchsen 2a und einem Unterbrecherkontakt 2b angeordnet. Im Meldereinsatz M ist die Kontaktstiftleiste 9 mit den Kontaktstiften 9a und dem Betätigungsstift 9b.As in the past, the division between detector registration and actual detector was maintained. The

Der Meldereinsatz 4 ist drehbar in der durchgehenden, d.h. umlaufenden, Melderkappe 5 angeordnet und in der Endlage über eine lösbare Verriegelung bzw. Arretiervorrichtung 6 arretierbar. Im Meldereinsatz 4 befindet sich das Sensorsystem 7, das ein optischer, ein Wärme- oder ein Kombinationsmelder sein kann. Ferner ist dort die Leiterplatte 8 mit den Baugruppen 8a, die auch in SMT-Technik ausgeführt sein kann. In diesem Ausführungsbeispiel ist eine vierpolige Kontaktstiftleiste 9 mit einem Betätigungselement 9b für den Unterbrecherkontakt 2b vorgesehen. Eine Identifikationsanzeige 10, die an der Leiterplatte 8 angeschlossen ist, steht mit einem Lichtleiter 11 in Verbindung, um das Licht an die Außenseite der Melderkappe 5 zu führen. Der Meldereinsatz 4 ist so ausgebildet, daß sich eine Wanne 12 ergibt, die hermetisch abgeschlossen werden kann, indem sie - wenn es erforderlich ist - mit einem Verguß versehen wird.The detector insert 4 is rotatable in the continuous, i.e. circumferential, detector cap 5 arranged and locked in the end position via a releasable locking or locking device 6. The sensor system 7, which can be an optical, a heat or a combination detector, is located in the detector insert 4. Furthermore, there is the printed circuit board 8 with the assemblies 8a, which can also be implemented using SMT technology. In this exemplary embodiment, a four-pole
Wie aus der Fig.1 und den obigen Erläuterungen ersichtlich, ist ein vertikales Zusammenstecken der Kontaktstiftleiste 9 in den Anschlußblock 2 bzw. in die Kontaktbuchsen 2a erforderlich. Dies wird dadurch ermöglicht, daß im herausgenommenen Zustand, d.h. Meldereinsatz und Melderkappe sind aus der Melderfassung herausgenommen, die Lage der Verriegelungsnocken 13 und die Stiftleiste 9, durch die Verrastung (lösbare Arretiervorrichtung mit Feder 6a; siehe Fig.2) fest zugeordnet ist. Beim Einsetzen des Melders (Meldereinsatz 4 und Melderkappe 5) in die Melderfassung 1 zentriert sich zunächst der voreilende Zentrierring 4a. In diese Stellung kann der gesamte Melder nach links oder rechts gedreht werden, bis die Verriegelungsnocken 13 in die Verriegelungskulissen 14 eintauchen. Durch weiteres Einschieben des Melders (4,5) in die Fassung (1) wird die Arretiervorrichtung 6 gelöst, so daß die Melderkappe 5 nach rechts gedreht werden kann. Dabei gleitet der Verriegelungsnocken 13 auf der ansteigenden Kulissenfläche 14a (Kulissenführung) und erzwingt den vertikalen "Steck"-Hub (h) für die Kontaktierung. Das Herausnehmen des Melders erfolgt in umgekehrter Reihenfolge.As can be seen from FIG. 1 and the explanations above, a vertical connection of the
