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 members.
  • the known fire detectors which are constructed as ionization detectors, optical detectors or 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 2 539 655 (as a central bayonet lock) ) and DE-GM 78 23178.4 (rotationally symmetrical connector) explained.
  • connection systems could not fully satisfy. Although it was possible to improve individual disadvantages of existing designs, other disadvantages had to be accepted. In particular, corrosion problems arise in the course of the use of a detector, which can severely impair or endanger not only the electrical contact but also the mechanical connection elements.
  • the detectors are often used in 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 overhaul, 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.
  • the connecting device which is characterized by an arrangement of at least three connecting elements on the circumference of the base part and of grooves having contact springs on the circumference of the side of the detector insert facing the base part, the connecting elements and the grooves sc engaging with one another ensure that a first partial detachment of the detector insert establishes the mechanical connection and a subsequent, rectified, second partial rotation of the detector insert establish the electrical connection.
  • 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 dashed lines in FIG. 4 and will be explained in more detail later with reference to FIG. 6. 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.
  • the Fig. 5 in a partial sectional view showing the detector unit 3.
  • This detector unit 3 comprises in its housing 15 elder part the actual M, which is not shown.
  • the grooves 8 which are distributed in the same number and at the same distance on the circumference, as connecting elements 2 are present 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.
  • An alarm indicator 10 in the detector insert 3 is shown in FIG. This alarm indicator 10 lights up when the detector has responded. According to the embodiment of FIGS. 5 and 6, the alarm indicator 10 represents part of the mechanical coding device.
  • the inner edge of the groove 8 is formed such 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 such that the contact spring 1 lies flat against the inner edge when on the contact spring 1 acts from the outside a radial force without contact between the contact spring 1 unc derr in the working position. inner edge of the groove takes place. It is hereby achieved that if the contact springs 1 are not intended to be touched by any tools, such as e.g. Screwdriver, a plastic deformation of the elastic contact springs 1 is avoided.
  • the contact springs 1 are arranged in the grooves 8.
  • the grooves 8 have an outer wall that 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.
