Definitions

• the invention relates to contact equipment for communication between electronic units in the form of terminal blocks mounted on mounting rails, preferably for use in process control systems.
• a large number of external transducers or actuators are used, which are to be connected to a process computer via interface CBs in the process computer system.
• the task of the interface CBs is to convert signals from transducers/actuators to a computer or vice versa.
• this connection is arranged by placing an optional number of terminal blocks in rows adjacent to the CBs on the cubicle frames. These terminal blocks serve as connection and distribution terminal blocks, to which external transducers are connected by cross- interconnections . From the terminal blocks there extend, in turn, connection leads to the CBs concerned. Voltage supply or other supply of the system may also be arranged by uti- lizing the terminal blocks as contact and connection devices.
• terminal blocks are fixed to the cubicle frames on mounting rails in the form of rails, which are normally made of metal.
• the rails are usually provided with flanges, onto which the terminal blocks are normally snapped by means of snap-in members below the terminal block. Terminal blocks are then placed in rows side-by-side on the mounting rail.
• These rails are provided in standard designs, for example in accordance with DIN standard EN 50 022 and 50 035.
• electrically conducting paths are arranged on the mounting rail.
• the conducting paths consist of elec ⁇ trically conducting strips of thin foils or elevated ridges of electrically conducting material applied to the mounting rail with insulating material between the conducting paths and the mounting rail.
• One or more conducting paths may occur parallel to one another.
• the conducting paths are positioned on the flanges of the rail, on the upper or lower side thereof, either on one of or both of the flanges.
• conducting paths are provided on the bottom of the mounting rail, that is, on the surface which is bounded by the flanges of the mounting rail. It is, of course, possible to provide both flanges and rail bottom with conducting paths .
• Terminal blocks of various kinds are placed and snapped onto the mounting rail. These terminal blocks are equipped with contact pins located below the terminal block for pre ⁇ determined contact with a certain conducting path on the mounting rail which corresponds to the position of the con ⁇ tact pin on the terminal block.
• the contact pins are con ⁇ nected directly, or via a contact device, to any of the con ⁇ ducting paths and bring about good electrical connection between conducting paths on the mounting rail and the con ⁇ tact pins with a corresponding location on the terminal block.
• Figure 1 and Figure 2 illustrate two examples of different types of mounting rails with ' flanges, the rails being provided with electrically conducting paths on an insulating foil or an insulating layer of some other kind.
• Mounting rails 1, 2 of standard type, for example according to DIN standard, such as of type EN 50022, EN 50035 or another type, are provided with electrically conducting paths 3 on the surface or surfaces of the mounting rail.
• the conducting paths 3 consist of electrically conducting foils, ridges or elevations, for example a thin copper foil, in one or several foils, applied to an insulating layer 4, 5 in the form of, for example, a thin plate or foil.
• the insulating layer or layers 4, 5 with the conducting paths 3 is/are applied to the surface of the mounting rail.
• the layer 4, 5 may be self-adhesive or is applied against the rail surface by some other form of pasting or adhesion.
• Mounting rails 1, 2 may also be prefabricated so as to be provided from the start with the conducting paths 3 on insulating layers 5, in which case these layers 5 may be made in any optional manner. In that case it is also possible to integrate insulating layers 5 with the mounting rail 1, 2 itself as a constituent thereof.
• the conducting paths 3 are located on top of the flanges 6, 7 of the mounting rail and also below these flanges if desirable. Alternatively, or as a combination, conducting paths are also located in the bottom 8 of the mounting rail. A conducting path 3 need not run along the entire extent of the mounting rail 1, 2.
• the insulating layer 4, 5 with conducting paths 3 is so wide that it covers only one flange 6 or both flanges 6, 7, or the bottom 8 of the mounting rail, or the entire width of the mounting rail, or any combination of these variants.
• the conducting paths are made in the form of printed circuit boards for electronic components .
• the conducting paths 3 are in the form of con ⁇ ducting foils or surfaces on an insulating layer 4 which is applied to the mounting rail.
• the mounting rails used in connection with the present in ⁇ vention may, of course, exhibit shapes entirely different from those described with reference to Figures 1 and 2.
• the inventive concept is applicable to an optional cross section of the mounting rail, also with, for example, more than two flanges.
