Definitions

  • 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.
  • 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.
  • 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.
  • 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.
  • detectors require complex contacts both in the Detection detection as well as in detector use.
  • the wiring cumbersome, especially if three or four electrical connections were necessary.
  • the detector inserts have a mechanical lock in the form of a bayonet lock. That means inserting and rotating the detector insert.
  • Such a bayonet lock is, for example, from US 4,315,594 known for an automatic fire detector.
  • US 4,315,594 known for an automatic fire detector.
  • 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.
  • 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.
  • 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.
  • 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.
  • the object of the invention is to overcome the disadvantages described above avoid and create an automatic fire alarm, which is a simple, quick and yet reliable installation allows.
  • Detector base formed by a detector holder on the ceiling with a centrally arranged fastening device, for example, can be fastened with a screw.
  • the contact device is of several in one contact holder block snap-in contact springs, each contact spring is formed at its free end as a compression spring. On hers the other end is each contact spring as a spring-loaded terminal trained in which the message line are connected can.
  • Part of the measuring system is in the detector cap (Sensor system) integrated.
  • the circuit board made with electronic Components is equipped, shows the supplemented part of the Detector system (sensor system) and is in the alarm cap arranged mechanically lockable.
  • the detector cap itself is without rotating movement on the detector holder by means of a snap device snapped.
  • the compression springs make contact on the correspondingly assigned contact areas of the circuit board the circuit board.
  • a snap hook is provided.
  • the electrical components which can be formed by SMD components, can expediently be provided with a corrosion protection.
  • the automatic fire detector is designed, for example, as an optical smoke detector which has the essential part of the sensor system on the printed circuit board, the supplementary part of the sensor system, including the labyrinth, being integrated in the detector cap.
  • the invention is briefly explained using the example of an optical smoke detector.
  • the two Figures 1 and 2 show an optical smoke detector in different embodiments shown in section.
  • the detector holder MH is arranged centrally a fastening device BV in the form of a screw on.
  • This single-hole assembly allows a simple and extreme quick installation of the optical smoke detector.
  • the detector holder MH has a contact block KB in which, for example four contact springs KF are arranged.
  • These contact springs KF are designed according to the invention so that they on the one hand with their free end as compression springs DF the corresponding Contact the assigned contact area KFL of the PCB LP, if the detector cap MK on the detector holder MH is latched.
  • the other end of the contact spring KF is designed as a spring clamp FKK, into which the wire the reporting line is simply plugged in and by means of the Spring force ensures safe contact.
  • the circuit board LP is with the necessary electrical and electronic components BE and SB.
  • the circuit board LP can be mechanically locked in the MK detector cap arranged what in another embodiment in Figure 2 is shown.
  • the circuit board LP can protect the Components SB have a corrosion protection KS.
  • the detector cap In addition to a detector indicator, MK shows the MAN and the required optical devices a labyrinth L and RO smoke inlet openings.
  • the MK detector cap with the integrated circuit board LP, both together the electronic and form optical sensor system, will only by snapping onto the MH detector holder with this both mechanically and electrically connected.
  • Figure 2 shows schematically in section another embodiment an optical smoke detector. This is according to the design similar to Figure 1 and has the same reference numerals.
  • the snap device SV is shown, by means of which the Detector cap MK only snapped onto the detector holder MH are needed.
  • the mechanical is also shown here schematically Locking MA of the PCB LP in the detector cap MK in Shown as a snap hook.
