    description
    SURGE PROTECTION EMBLEM The invention relates to a surge protection ensemble.
    BACKGROUND
    In many areas of technology, electrical signals are fed to a processing station by wire. Typically, the wire connections are designed to be detachable. E.g. In railway technology, a large number of cables from sensors and signal systems are brought together at certain switching points in order to be processed there. The signals are made available via signal terminals from an outside area to an inside area.
    For safety-relevant systems, it is also desirable that surge protection is provided. Overvoltage protection devices typically have to be checked regularly to determine whether they still have the necessary protection capability.
    The problem then often arises that the fuse protection has to be removed from the corresponding signal path without the signal path being interrupted.
    PRIOR ART [0005] Numerous solutions are known from the prior art.
    For example, from the German patent DE 10 2014 217 446 B4 it is known to equip two signal terminals with an adjacent ground terminal, with overvoltage protection being provided from the signal terminals to the ground terminal by means of a plug-in module.
    Furthermore, from the applicant's German patent application DE 10 2014 218 646 A1, an arrangement of two signal terminals with a ground terminal in between is known. Overvoltage protection is provided from the signal terminals to the grounding terminal by means of a plug-in module.
    Furthermore, from the applicant's German patent application DE102014213728, a series terminal arrangement is known in which an overvoltage module spans a series terminal and a grounding terminal.
    However, all the solutions presented have in common that a large amount of space is required. Therefore, the previous solutions are particularly unsuitable when in a confined space, e.g. In the case of existing cabling, the previously unprotected signal paths should be supplemented by security solutions of the aforementioned type, as this usually requires a% more space than before.
    In addition, the solution is costly since a different type of clamp must be provided. Furthermore, strict attention must be paid to the exact arrangement during assembly, otherwise the desired safety function will not be available.
    Against this background, it would therefore be desirable to provide a simple, inexpensive solution that avoids one or more disadvantages of the prior art.
    According to the invention, the object is achieved by the features of the independent claim. Advantageous embodiments of the invention are specified in the subclaims, the description and the figures.
    The invention is explained in more detail below with reference to the attached drawings using preferred embodiments.

    The invention will be illustrated in more detail below with reference to the figure. It should be noted that different aspects are described that can be used individually or in combination. I.e. any aspect can be used with different embodiments of the invention unless explicitly shown as a pure alternative.
    Furthermore, for the sake of simplicity, reference will generally only be made to one entity in the following. Unless explicitly stated, the invention can also have several of the entities concerned. In this respect, the use of the words “a”, “an” and “an” is only to be understood as an indication that at least one entity is used in a simple embodiment.
    As far as methods are described below, the individual steps of a method can be arranged and / or combined in any order, unless the context explicitly results in something different. Furthermore, the processes can be combined with one another - unless expressly indicated otherwise.
    Information with numerical values are generally not to be understood as exact values, but also include a tolerance of +/- 1% up to +/- 10%.
    As far as standards, specifications or the like are named in this application, at least the standards, specifications or the like applicable on the filing date are always referred to. I.e. if a standard / specification etc. is updated or replaced by a successor, the invention can also be applied to this.
    The figures show an overvoltage protection ensemble. The overvoltage protection ensemble has at least one first signal terminal K1 for providing a first electrical connection L1 and a second signal terminal for providing a second electrical connection L2.
    The overvoltage protection ensemble also has an overvoltage protection plug USS. The exact wiring of the overvoltage protection plug USS is initially irrelevant.
    The first signal terminal K1 and the second signal terminal K2 are set up for directly adjacent assembly on a mounting rail T. The support rail T can be a suitably metallized or metallic profiled (steel / copper / aluminum) rail in a suitable form, e.g. as a top hat rail or G-rail. As an example, reference is made to mounting rails according to DIN EN 60715.
    In this case, at least the first signal terminal K1 has a device E for making electrical contact with the mounting rail T for making electrical contact with an equalizing potential BE, PE, GND. Equalizing potential can be a suitable general reference potential ground BE, a personal protection ground, a general ground connection GND or any other suitable potential.
    The overvoltage protection plug USS protects in the inserted (second) state, see e.g. Figure 5 - the first electrical connection L1 and the second electrical connection L2 against overvoltage.
    In this case, when the overvoltage protection plug USS is plugged in, an electrical connection to the device E for making electrical contact with the mounting rail T is provided at least to the first signal terminal K1.
    In other words, at least the first signal terminal K1 provides both a connection of the signal path L1 from the outside area to an inside area and a separate path to the mounting rail T. The overvoltage protection plug USS only provides the corresponding wiring of the signal path L1 or the signal paths L1 and L2 to the mounting rail T. I.e. in the unplugged state - see, for example, FIGS. 2 and 4 - the potential of the support rails T is present at a suitable plug-in position via the device E on the terminal block, but no further contact is made.
    With this novel configuration, overvoltage protection is thus made available with the same space requirement on a mounting rail T.
    In one embodiment of the invention, the first signal terminal K1 and the second signal terminal K2 are designed essentially identically. I.e. with the provision of identical parts, the manufacturing and development costs can be reduced. In addition, assembly is simpler and fail-safe, as it is now no longer necessary to track which type of terminal is installed next to another terminal.
    In a further embodiment of the invention, the first signal terminal K1 and the second signal terminal K2 can have a common housing, i.e. be integrated, the electrical connections L1, L2 provided being arranged next to one another. Such a solution can e.g. be advantageous if a larger contact E for contacting the mounting rail T is advantageous, e.g. for discharging high currents.
    Without further ado, both the first signal terminal K1 and the second signal terminal K2 can each have a cutting knife TM1, TM2. A signal path can be separated using cutting blades without the need to mechanically loosen the connected signal line. Shift locks (optional) can easily be provided. In a separated signal path, e.g. Current measurements are carried out.
    Furthermore, a labeling option can also be provided on the signal terminals according to the invention.
    Without loss of generality, the signal paths at the signal terminals can be in different techniques, e.g. be provided in screw, clamping, push-in technology or the like.
    In a further embodiment of the invention - see Figure 1, 8 and 9 - the overvoltage protection plug USS has one or more contact elements KE1, KE2 for checking and / or reading operating data and / or parameterization, the contact element KE1 / the contact elements K1 / K2 are spatially accessible even when plugged in. I.e. the overvoltage protection element can also be checked / read out / parameterized when it is plugged in, thus eliminating the need to remove it.
    According to a further embodiment of the invention, the overvoltage protection plug USS has at least one varistor VAR and / or a suppressor diode TVSD and / or a gas discharge tube GDT and / or a voltage-limiting element. Different circuits can be implemented, the circuits shown in FIG
    VF circuit (with an optional second connection in the second signal terminal K2 to the mounting rail T), in Figures 3, 9 a so-called 1x2 circuit (with an optional second connection in the second signal terminal K2 to the mounting rail T) and in FIG so-called 2 circuit.
    E.g. An embodiment can be seen in FIGS. 2 and 6 which is suitable for the VF circuit or the “2” circuit, while an embodiment can be seen in FIGS. 4, 5 and 7 which is suitable for a 1x2 circuit.
    According to yet another embodiment of the invention, which is shown in Figure 9, the first signal terminal K1 in the signal path of the first electrical connection L1 has a low electrical resistance R1 and / or the second signal terminal K2 in the signal path of the second electrical connection L2 low electrical resistance R2. A low electrical resistance is typically less than 10 ohms.
    Even if the resistor R1, R2 is shown above as a component of the respective signal terminal, this does not necessarily have to be so. For example, it is also possible to integrate the resistor (s) in the overvoltage protection plug USS. For example, it can then be provided that when the overvoltage protection plug USS is inserted, the direct signal path is only separated after the electrical connection to the resistor has been established.
    The different circuit types can be designed for different requirements.
    A suitable coding in the connection area of the overvoltage protection plug USS and / or in the connection area of the respective signal terminal K1, K2 can easily ensure that only certain combinations are possible.
    As is readily apparent from the circuit diagrams, an overvoltage protection plug USS requires at least a connection to a first signal path L1 and to the second signal path L2 and at least one further connection to the equalization potential, i.e. to the potential of the mounting rail T made available to at least one of the signal terminals K1, K2.
    Even if the invention was described above only with reference to a two-wire system, the usability of the idea is not limited to this. For example, overvoltage protection for three-phase systems can also be made available with a suitably designed overvoltage plug USS. In this case e.g. 3 or 4 signal terminals of the same type are used, with a contact to the equalizing potential being made available in at least one of the signal terminals.
