Definitions

  • the invention relates to a connecting device for a fire detector which consists of a base part fastened in the room to be monitored and a detector part which can be connected to it by means of electrical and mechanical connecting elements, at least three connecting elements on the circumference of the base part and grooves having contact springs on the circumference of the base part facing side of the detector insert are arranged.
  • the known fire detectors which are constructed as ionization detectors, optical detectors or as heat-sensitive detectors or the like, generally consist of a base part mounted on the ceiling or wall of the room to be monitored and of a detector insert which is inserted into the base part. This detector insert is either connected to the base part by means of fixed terminals or by means of a contact system.
  • the various exemplary embodiments are shown in FIGS. 1, 2 and 3 and in CH-PS 355 380 (plug connection according to the electron tube principle), in CH-PS 508 251 (as a bayonet lock), in DE-AS 2E39655 (as a central bayonet lock) and DE-GM 7823178.4 (rotationally symmetrical connector) explained.
  • the detectors are often used under very harsh environmental conditions, they are exposed to corrosive vapors, high air humidity, dust deposits or the like. Frequent malfunctions of detectors result from mechanical damage to the contact springs by the service personnel.
  • the known fire detectors try to take this problem into account by arranging the movable part of the electrical contact system (contact spring) in the base part 4 and the rigid part of the electrical contact system in the detector insert.
  • the contact springs 1 will be bent during the revision, which leads to an impairment of the detector function.
  • the invention has for its object to eliminate the disadvantages of the known detectors, that is to create a connecting device of the type mentioned, which makes it possible to remove the detector insert with simple means from the base part, the electrical contacts against accidental contact by the Service personnel are protected and the electrical contact surfaces between the base part and the detector insert are arranged parallel to the axis of the entire detector to reduce the risk of contamination of the contact surfaces from deposits reduce.
  • the connecting device which is characterized in that the connecting elements and the grooves come into engagement with one another in such a way that a first partial rotation of the detector insert establishes the mechanical connection and thereby ensures that the electrical connection is prevented during this first partial rotation and that only a subsequent, rectified, second partial rotation of the detector insert establishes the electrical connection between the contact surfaces of the connecting elements and the contact springs arranged parallel to the detector axis.
  • FIG. 4 shows the top view of the base part 4 of the fire detector.
  • Three connecting elements 2 are fastened on the circumference. They form an angle of 120 ° to each other. Of course, four or more connecting elements 2 can also be distributed over the circumference. The distribution does not have to be uniform as shown in Fig.4.
  • Each connecting element 2 is bow-shaped. Its part 7, which is arranged radially to the axis of the base part 4, carries the contact surface 6, on which the contact spring 1 arranged in the detector insert 3 comes to rest. This is shown in broken lines in FIG. 4 and will be explained in more detail later with reference to the FIG. In the bottom of the base part 4, fastening holes are provided, which are drawn with dashed lines.
  • the connecting elements 2 are arranged between the outer edge 13 and the inner edge 14. Both edges are integrated with the bottom of the base part 4.
  • the inner edge 14 contains recesses 12 which form part of the mechanical coding device. The purpose of this coding device is that the detector insert 3 and base part 4 always come into engagement in the correct position. This prevents incorrect electrical contact, which can damage the electrical equipment not only of the fire detector, but also of the control center.
  • FIG. 5 shows a sectional view of the base part 4, which is attached to the ceiling or on the wall of the room to be monitored.
  • the individual parts have the same reference numerals as described in connection with FIG. 4.
  • FIG. 5 shows a partial sectional view of the detector insert 3.
  • This detector insert 3 contains the actual detector part in its housing 15, which, however, is not shown.
  • the grooves 8 which are distributed in the same number and at the same distance over the circumference as there are connecting elements 2 in the base part.
  • the upper part of the detector insert 3 contains a part 11 of the mechanical coding device which, in cooperation with the recesses 12 (FIG. 4), produces the coding.
  • the outer wall of the grooves 8 has an edge 5 which, in cooperation with the radial part 7 of the connecting element 2, results in the mechanical connection between the detector insert 3 and the base part 4.
  • 5 shows an alarm indicator 10 in the detector insert 3. This alarm indicator 10 lights up when the detector has responded.
  • the alarm indicator 10 represents part of the mechanical coding device.
  • the inner edge of the groove 8 is formed so that in the working position between the contact spring 1 and the inner edge of the groove only a narrow gap remains, which is designed so that the contact spring 1 lies flat against the inner edge when on the contact spring 1 acts from the outside a radially directed force without contact between the contact spring 1 and the inner edge of the groove taking place in the working position. This ensures that when you do not want to touch the contact springs 1 by any tools such. B. screwdriver, a plastic deformation of the elastic contact springs 1 is avoided.
  • FIG. 6 shows the top view in a partial sectional view of the side of the detector insert 3 which faces the base part 4 and engages with it.
  • the contact springs 1 are arranged in the grooves 8.
  • the grooves 8 have an outer wall which is so far advanced that only a very small recess 9 makes the connection to the outside.
  • the part of the mechanical coding device which has already been discussed in more detail in connection with FIG. 5, is designated by 11.
