Definitions

  • the interchangeable modules that can be detached without tools and temporarily connected to one another are more widespread in so-called “not preconfigured” devices or signal towers.
  • the individual modules in particular lighting modules and/or acoustic modules, can be combined with one another as desired and can also be exchanged or exchanged at a later point in time without the use of tools.
  • This achieves a particularly high level of flexibility in the possible applications with standardized interchangeable modules. For example, a "blue" stage or interchangeable module can be added later and/or a damaged or broken light module/interchangeable module can be replaced with a new, intact light module/interchangeable module without great effort.
  • a signaling tower wherein a circuit board or circuit board is used, which is aligned in the longitudinal direction of the signaling tower.
  • the printed circuit board is permanently contacted with wires during operation or use. These wires extend radially outwards to the inside of the calotte, the contact points between two adjacent or between two detachably connectable interchangeable modules/modules, which are to be detached for the disassembly of the respective module, being realized on the inside of the calotte.
  • the contacting between the individual interchangeable modules/lighting modules with wires which has been common for many years, is also implemented here.
  • connection element is characterized in that the electrical conductor having the contact surface for connecting an adjacent functional module for the electrical connection of the contact surface to a wire of an electrical cable extends to a cable connection terminal of the connection element.
  • a special embodiment of such a terminal is when a passage for inserting a wire end of a cable is provided in the cable clamping spring. As a result, the wire end of a cable is clamped more stably and contact is made more reliably.
  • Such clamps are also referred to as so-called cage clamps.
  • a further development of the invention offers particular advantages in which a device for releasing the cable clamping spring is provided.
  • the connection element or an associated signaling device can easily be disconnected from the external cable.
  • the release of the cable clamp spring can be effected, for example, by providing access for a separate tool such as a screwdriver to depress the cable clamp spring, or by providing a permanent release element such as a movable lever or plunger for depressing the cable clamp spring.
  • the contact surface for the adjacent function module is a surface of a contact spring which is resilient transversely to the contact surface and acts in the direction of a longitudinal axis of the connection element.
  • a contact spring has already proven itself in designs in which the printed circuit board running parallel to the longitudinal axis of the corresponding functional module has the mating contacts on the end face has, so that the contact is closed with the pressing of a front-side contact to the contact spring. Due to the design as a contact spring, there is also a tolerance compensation when connecting several parallel contacts via the possibility of different spring deflections.
  • the resilient contact surface can be flat or have sloping sliding surfaces or ramps at the end for the sliding of the mating contacts of a corresponding printed circuit board.
  • the contact spring for the adjacent functional module is electrically connected to the cable clamping spring, the connection of the external cable to the cable clamping spring results in a ready connection for the adjacent functional module directly via the contact surface of the contact spring for the adjacent functional module.
  • the electrical connection of two or more electrical lines of the adjacent function module is made possible in that two or more spring elements of the same shape as electrical conductors with contact surfaces for the adjacent Function module are provided, wherein the contact surfaces are arranged side by side and pointing in the direction of the longitudinal axis of the closing element.
  • connection element according to the invention is advantageously used in a signaling device with interchangeable function modules, such as, for example, in a signaling column.
  • interchangeable function modules such as, for example, in a signaling column.
  • an additional advantage can be achieved in that one or more function modules have a contact element that is designed in the same way as the contact element of the connection element.
  • the same contact elements can be used not only between the connection element and the adjacent functional module or element, but also between the functional modules or elements.
  • the contact element has both a cable clamp for the cable ends and connection contacts for a functional module or element, for example for a printed circuit board of a functional module.
  • the contact element 7 includes an electrically insulating receptacle 8, for example made of plastic, in which a spring element 9 is used as an electrical conductor.
  • the spring element On the upper side, the spring element has a contact surface 10 for the electrical connection of an adjacent functional element.
  • the spring element is supported in the receptacle 8 via two side walls 11 and in a manner that is not shown in detail anchored, for example by means of barbs, locking elements or the like.
  • a slot 16 in the receptacle 8 allows the insertion of a tool 17 shown in phantom, e.g. in the form of a screwdriver, in order to push the cable clamping spring 12 away from the ferrule 13 and thereby release it.
  • a tool 17 shown in phantom e.g. in the form of a screwdriver
  • FIG. 4 shows another embodiment of the spring element 9 of Cable clamping spring 12 with a modified counter bearing 14. Although a ferrule is shown in the illustration to illustrate the oblique direction of insertion here, the cable clamping spring is in the non-deflected position, which corresponds to the position without ferrule.
  • figure 5 shows the variant of the contact element 7 after Fig.1 , wherein the recording 8 is only partially shown.
  • the tool 17 is only indicated and is of course significantly larger in reality.
  • ferrules of different cross sections can be used.
  • the ferrule shown is significantly narrower than the associated receiving opening 19 in the receptacle 8, so that an inclined insertion position is possible here.
  • a ferrule 13 or a wire end of a cable wire with a larger cross-section could also be used.
  • the end of the spring element 9 forming the cable clamping spring is shaped in such a way that it forms a clamping cage 19 and a counter bearing 20 .
  • the ferrule is inserted through an opening 21 of the terminal cage 19 and clamped between the clamping cage 19 and the counter bearing 20 when springing back in the Z direction.
  • the clamping cage can be pressed against the spring direction Z by means of the tool 17 and the jamming of the ferrule 13 can thus be released again.
  • the spring element 10 shows a special embodiment of the design of the spring element 9.
  • the spring element 9 is shown here only partially to illustrate the cross sections.
  • the spring element is bent from a wire 21 with a round cross-section and flattened by an embossing 22 in the area of the cable clamping spring.
  • a comparable embossing or flattening can also be provided in the area of the contact surface 10 .
  • a printed circuit board 24 is in electrical contact with the contact surfaces 10 of the contact element 7 of the connecting element 1 with end contacts 25.
  • the printed circuit board 24 belongs to an adjacent function module, not shown in more detail, which is connected to the connecting element 1 and connected via it.
  • a signaling column which includes various functional modules 29, 30,31,32,33,34, which can be designed, for example, as light modules, acoustic modules or radio modules.
  • the connection element 1 which is not shown in detail in these figures, is designed according to the invention and is used to connect the function modules 29, 30, 31, 32, 33, 34 by means of cable wires, which are not shown. In the cut representation after 15 circuit boards 24 can be seen.
  • connection of a function module for example the function module 30 or 31 to 33
  • the printed circuit board 35 is provided on the lower end face with end-face contacts 36 in the form of electrically conductive contact surfaces which, as can be seen, run transversely to the longitudinal axis A of the signaling column 28 , the function modules 29 to 34 and the printed circuit board 35 .
  • These end-face contacts 36 form counter-contacts to the contact surfaces 10 of the contact springs 18, which are also transverse to the longitudinal axis A, in the contact element 7 of a functional module 31 below or of a connecting element 1 below.
