Abstract
Description
Die Erfindung bezieht sich auf einen automatischen Brandmelder mit einem Meldersockel mit einer elektrischen Kontaktvorrichtung und einer mechanischen Verriegelungsvorrichtung und mit einem Meldereinsatz mit einer Leiterplatte sowie mit einer Melderkappe, welche mechanisch und elektrisch miteinander verbindbar sind.The invention relates to an automatic fire detector with a detector base with an electrical contact device and a mechanical locking device and with a detector insert with a printed circuit board and with a Detector cap, which mechanically and electrically with each other are connectable.
Im allgemeinen sind automatische Brandmelder zweiteilig ausgebildet, dabei ist die Melderfassung mit mehreren Schrauben fest an der Decke installiert, wobei in die Melderfassung 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 abgedeckt. Für den elektrischen Anschluß waren bisher beispielsweise drei oder vier, im allgemeinen gleichförmig auf dem Kreisrand der Melderfassung verteilte 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.In general, automatic fire detectors are made in two parts, the detector is with several screws permanently installed on the ceiling, with one in the detector socket removable detector part can be used. The detector part itself consists of a circuit board with the necessary electronic components and the actual detector system and a detector cap that covers the whole. For the electrical connection was previously three, for example or four, generally uniform on the circular rim of the Distributed sliding contacts are provided to which the Wiring was clamped. The detector insert pointed accordingly arranged contacts by turning the detector when inserting the mechanical lock at the same time took over. To ensure good locking, was an even distribution of the contacts on the circumference required.
Aus CH 633 122 ist beispielsweise ein Melder bekannt, der ein Sockelteil und ein Melderteil aufweist, wobei die notwendigen Verbindungsorgane rotationssymmetrisch ausgebildet und koaxial angeordnet sind. Dadurch kann der Melderteil in den Sokkelteil in beliebiger Winkellage eingesetzt werden und behält seine Verdrehmöglichkeit zum Sockelteil. In einem Ausführungsbeispiel sind dabei die rotationssymmetrisch angeordneten elektrischen Kontakte im Sockelteil als gefederte Ring- bzw. Plattenkontakte ausgebildet, die mit Kontaktstiften, welche der Leiterplatte des Meßsystems im Melderteil zugeordnet sind, nach dem Einsetzen in Verbindung stehen.From CH 633 122, for example, a detector is known, the one Has base part and a detector part, the necessary Connecting organs formed rotationally symmetrical and coaxial are arranged. This allows the detector part to be placed in the base part can be used in any angular position and retains its ability to twist to the base part. In one embodiment are the rotationally symmetrical electrical contacts in the base part as spring-loaded ring or plate contacts formed with contact pins, which is assigned to the circuit board of the measuring system in the detector part are connected after insertion.
Derartige Melder erfordern aufwendige Kontakte sowohl in der Melderfassung als auch im Meldereinsatz. Zudem ist die Verdrahtung umständlich, insbesondere dann, wenn drei oder vier elektrische Verbindungen notwendig waren. Darüber hinaus weisen in der Regel die Meldereinsätze eine mechanische Verriegelung in Forme einer Bajonettverriegelung auf. Das bedeutet ein Einsetzen und Verdrehen des Meldereinsatzes.Such detectors require complex contacts both in the Detection detection as well as in detector use. In addition, the wiring cumbersome, especially if three or four electrical connections were necessary. In addition point usually the detector inserts have a mechanical lock in the form of a bayonet lock. That means inserting and rotating the detector insert.
Ein solcher Bajonettverschluß ist beispielsweise aus US 4,315,594 für einen automatischen Brandmelder bekannt. Dort ist in der Beschreibung des Standes der Technik auch beschrieben, daß die elektrische Kontaktierung zwischen Sockel und Melderteil durch Kontaktfedern im Sockel und starre Kontakte im Melderteil realisiert wird.Such a bayonet lock is, for example, from US 4,315,594 known for an automatic fire detector. There, the description of the prior art also describes that the electrical contact between the base and detector part thanks to contact springs in the base and rigid contacts is implemented in the detector section.
In dem DE-GM-92 10 856 ist ein automatischer Brandmelder beschrieben, bei dem in der Melderfassung, die aus einem einfachen Spritzteil bestehen kann, ein mehrpoliger Anschlußblock mit den erforderlichen Steckbuchsen beispielsweise einrastbar angeordnet ist. Der Meldereinsatz weist eine Kontaktstiftleiste mit den entsprechenden Kontaktstiften 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, die als Zentrierungsring fungiert, auf. Die Melderkappe ist auf der Melderfassung mechanisch verriegelbar, wobei beim Einsetzen des Melders, d.h. Sensorsystem neben 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. Bei dem bekannten Brandmelder ist eine sichere und zuverlässige, jedoch sehr aufwendige elektrische Kontaktgabe und mechanische Verriegelung zwischen dem eigentlichen Melderteil und der Melderfassung gewährleistet. Der bekannte Melder ist jedoch sehr kostenintensiv konstruiert. Ebenfalls ist der Montageaufwand mit mehreren Befestigungsschrauben aufwendig. Der mehrpolige Anschlußblock weist mehrere Anschlußklemmen für die Anschlußdrähte der Meldeleitung sowie mehrere Anschlußbuchsen auf, in welche Kontaktstifte des Meldeeinsatzes eingesteckt werden müssen. Dabei muß diese Kontaktvorrichtung so ausgebildet sein, daß auch noch eine Drehung des Meldereinsatzes möglich ist.An automatic fire detector is described in DE-GM-92 10 856, in which in the registration, which consists of a simple Injection molded part can consist of a multi-pole terminal block snap in with the required sockets, for example is arranged. The detector insert has a contact pin strip with the appropriate contact pins on the connector block assigned when the detector is inserted become. Therefore, the detector insert is rotatable in the rotating one Detector cap arranged and lockable in its end position. For this purpose, the detector insert has a peripheral side wall, which acts as a centering ring. The detector cap is mechanically lockable on the detector, whereby when inserting the detector, i.e. Sensor system next to detector insert and detector cap, one molded onto the detector cap Locking cam in a slanted link guide a locking link is guided. The locking backdrop is arranged on the detector so that a vertical stroke for contacting is achieved when the detector is inserted and screwed in. With the well-known Fire detector is a safe and reliable, however very elaborate electrical contact and mechanical locking between the actual detector part and the detector acquisition guaranteed. However, the known detector is very expensive constructed. The assembly effort is also expensive with several fastening screws. The multipole Terminal block has several terminals for the connecting wires the message line and several connection sockets on, in which contact pins of the signaling insert are inserted have to. This contact device must be designed in this way be that a rotation of the detector insert is also possible is.
