Description

The invention relates to the Schirmleiter- and / or earth or Funktionserdverbindung of one or more cable connectors and / or an electronic device with such connectable or connected cable (round) connectors or (round) connector cables, in particular fieldbus slave device, for Evaluation and / or control of the signals of at least one internal or external sensor and / or actuator, in particular a Profibus, Profinet, Industrial Ethernet and EtherCat slave device with two cable connector-based fieldbus connections as fieldbus input or output ,

Connection cable with idR. standardized connectors, in particular widespread circular connectors, z. B. M12 straight or 90-degree angled, are often used in automation systems to connect sensors or actuators with controllers or power supplies. About the connection cable is a supply of sensors or actuators, at the same time analog switching signals and / or data are transmitted. For secure connection of a circular connector with a corresponding counterpart is a screw that is designed as a union nut plug cable / connector or as a threaded sleeve in the mating connector (through socket or wall socket or cable connector socket coupling). Unwanted electromagnetic interference can cause system malfunctions. This z. B. output from sensors wrong switching signals. The disturbing influences can be inductive or capacitive or galvanic disturbing influences. In particular, in the vicinity of high-performance electric motors and similar actuators can cause significant disturbances. In order to prevent interference of individual components in a system by electromagnetic interference, often shielded connector cables are used and / or prescribed, which are considerably more expensive than unshielded cables. The shielded connection cables usually have cable screens made of a non-magnetic material such as copper or aluminum. Frequently, the cable screens are made up of braided monoplanes made up of oppositely interwoven sets of wires. The density and strength of the wire mesh are crucial for the quality of the shielding. Frequently, the shield or the cable shield is only connected at one end of the cable to ground, ground, functional ground or a similar reference potential. In order to suppress magnetic or fault current interference, the cable shield must in certain cases be "put on" at both ends of the cable. However, there is the danger of a ground loop. Ground loops arise in particular when two points of grounding are connected to one another via different electrically conductive paths. The ground connection in this case is a closed loop. Ground loops can cause the shield to generate very large currents under circumstances that contribute to interference on the signal lines. In the industrial sector, two earthing concepts have become established. In the tree structure, all ground connections to a defined collection point are managed separately. The mesh structure has multiple grounding points connected together. The individual shielding concepts are optimized for certain disturbing influences. In order to be able to realize different shielding concepts, the providers of shielded connection cables offer different cable variants. For a first cable variant, the shield is not attached. In a second cable variant of the screen is placed on both sides, d. H. the respective union nut or the threaded sleeve of the circular connector is at reference potential. In a third variant of the shield is placed and additionally connected to the pin 5 of the (Profibus) circular connector. When planning a system, the user must decide on a specific shielding concept and then wire the individual system components accordingly. However, it is only when commissioning a system that it becomes clear whether the chosen shielding concept actually brings the desired success. If the function of the system continues to be affected by electromagnetic interference, the wiring must be replaced in a complex manner or other costly measures are taken to reduce or eliminate the interference.

• • kapazitive Erdung an einem Ende des Schirms (Anschluss des Schirms an den Potenzialausgleich über einen Kondensator), harte Erdung am anderen Ende

In industrial fieldbuses such as Profibus-485, Profibus-DP, Profibus-PA and Profinet, especially in Industrial Ethernet-based, it is common and necessary Slavegeräte with a metallic housing on shielded multi-pin M12 cable circular connector with a round plug and a round socket with each other and with other components by screwing together by means of union nut with each other, since the shield line must be galvanically low-impedance of an electronic evaluation and / or control unit to another because of the line wiring "looped" must. Such union nuts are electrically conductive and with the cable shield permanently or temporarily or switchable galvanically connected, see, for. B. the German patent application 10 2011 078 622.8 , Such slave devices have at least two integrated and fixed in their housing wall connector complementary and / or non-complementary type as a wall or Einbaurundsteckverbinderpaar. Such a built-in circular connector pair incorporated in a metallic housing each has a metallic housing with a terminal on the inside of the housing as a solder tail in the secondary terminal compartment (interior space). In the outdoor area are the two Screw-in elements of the recessed round connector pair as housing part with internal thread for the mating connector on the cable and as housing part with external thread for the mating connector socket on the cable. Some fieldbus cables, in particular Profibus cables, must be terminated with their characteristic impedance. The bus must be terminated at the respective last station by connecting a terminating resistor. In systems with more than two stations, all participants are wired in parallel. To do this, the fieldbus cable and its shield must be looped through without interruption. The cable connector types recommended in many fieldbus systems have an (outer) shield which is galvanically connected to conductive parts of the connector housing, in particular to its manually rotatable parts (union nut, male threaded sleeve). This shield should be earthed for EMC protection reasons. This is basically possible in different ways:

• • hard grounding of the shield on both sides (connection between shield and equipotential bonding
• • capacitive grounding at one end of the shield (connecting the shield to equipotential bonding via a capacitor), hard ground at the other end
• • hard ground at one end of the shield, no ground at the other end

Hard grounding at both ends of the shield provides the best EMC protection. In this case, an equipotential bonding conductor is required. If capacitive grounded at one end, in certain cases, for. For example, in non-Ex applications, the equipotential bonding conductor can be dispensed with. However, the EMC protection is not as good as applying the screen on both sides.

ETHERNET with the globally accepted TCP / IP protocol will most likely create an even better connection in the future to the established "field bus world" or to the sensor-actuator level, either via a gateway to the "fieldbus world" or consistently down to the lowest Level of communication hierarchy. The transfer rates are currently either 10 Mbit / s (ETHERNET) or at least 100 Mbit / s. (CAT5 requirements, Fast Ethernet = Industrial Ethernet) or CAT-6a or CAT-7 requirements). Basically, the ETHERNET world is divided in terms of transmission rates in: ETHERNET: about 10 Mbit / s; FAST ETHERNET about 100 Mbps; GIGABIT ETHERNET: about 1000 Mbps. Due to the very high transmission rates and frequencies, special requirements are to be taken into account for interference and radiation in the case of Ethernet-based fieldbus and sensor-actuator systems.

Common failure causes of fieldbus technology include transient electromagnetic disturbances that affect signal flow and destroy electronic devices. As the shielding can not be replaced in the industrial sector or the fieldbus slaves lose their immunity to interference due to inadequate shielding, users of fieldbus cabling must be particularly careful when installing them. All applications are particularly sensitive to potential equalization currents. The DIN VDE 0100 Part 540 defines the selection and installation of electrical equipment in the field of earthing, protective conductor and equipotential bonding conductor. It also defines basic security aspects. For this reason, it serves as the basic standard or basis for all other standards. Grounding is the electrical connection of a point of the operating circuit or of a body to the ground. The totality of all means and measures for earth is called grounding. A distinction must be made between plant earthing (earthing, which is necessary for operational reasons) and protective grounding (earthing, which is erected for protection purposes). It is permissible and common for an earth electrode to perform these two functions simultaneously. If one point of the operating circuit is earthed, it is an operating ground. If a body is earthed, then it is a protective earth. A Betrieberdung, that is, the grounding of a PEN conductor or other part of an operating circuit (pipe network, this can be done directly or indirectly).

• a) unmittelbar, wenn keine weiteren Widerstände zwischen dem zu erdendem Punkt und Erder vorhanden sind,
• b) mittelbar, wenn der Fehlerstrom durch das Erdreich durch ohmsche, induktive oder kapazitive Widerstände begrenzt wird.

A grounding is

• a) immediately if there are no further resistances between the point to be grounded and the ground,
• b) indirectly, if the leakage current through the ground is limited by ohmic, inductive or capacitive resistances.

A protective earthing is the connection of a point, which does not belong to the operating circuit, with the ground. This is mainly used to protect against the occurrence of excessive contact voltages. According to VDE100, in the standard TN low-voltage networks, the bodies of electrical equipment must be connected to the grounded point of the network through a protective conductor (PE) or the PEN conductor. By the body is meant here touchable parts of equipment, which are not part of the operating circuit. However, these bodies can be under tension in the event of a fault. in the trouble-free operation, the PE protective conductor does not carry any current. In contrast, the neutral conductor N serves as a return conductor for the operating currents of all between the outer conductors and switched single-phase loads. The currents arriving at the equipotential bonding rail, regardless of the presence of a connection with the foundation earth, flow back to the driving power source via the PEN. After part 600 of the VDE and ISO-IEC 11801 When testing the resistance for protective conductors and equipotential bonding conductors, it is necessary to ensure that there is a sufficiently low-resistance connection. There appear to be no requirements for the RF characteristics of grounding through the use of a Profibus cabling system. The corresponding requirements for the conductor resistance for copper cables can be found in the relevant standards. To DIN 57100 part 310 For example, a low voltage network in its entirety is described by a) the grounding ratio of the power source and b) the grounding ratio of the bodies.

• a) Für erhöhte EMV-Anforderungen Stecker mit Metallgehäuse oder einem Gehäuse aus metallisiertem Kunststoff und den Kabelschirm am Steckergehäuse auflegen
• b) Schirme an beiden Kabelenden möglichst großflächig auflegen
• c) Alle ungeschirmten Leitungen möglichst kurz halten
• d) Erdungsverbindungen möglichst kurz und mit großem Querschnitt ausführen (z. B. induktionsarmes Masseband, Flachbandleiter)
• e) Sollten zwischen den Maschinen- und Elektronik-Erdanschlüssen Potentialdifferenzen bestehen oder auftreten, so ist durch geeignete Maßnahmen dafür zu sorgen, dass über den Kabelschirm keine Ausgleichströme fließen können (z. B. Potentialausgleichsleitung mit großem Querschnitt verlegen oder Kabel mit getrennter 2fach-Schirmung verwenden, wobei die Schirme nur auf jeweils einer Seite aufgelegt werden)
• f) Signal- und Steuerleitungen räumlich von den Leistungskabeln getrennt verlegen

The following is recommended:

• a) For increased EMC requirements, place the connector with metal housing or a housing made of metallized plastic and the cable shield on the connector housing
• b) Lay umbrellas on both ends of the cable as large as possible
• c) Keep all unshielded cables as short as possible
• d) make earthing connections as short as possible and with a large cross section (eg low-induction ground strap, ribbon cable)
• e) If potential differences exist or occur between the machine and electronic ground connections, appropriate measures must be taken to ensure that no compensating currents can flow through the cable shield (eg route equipotential bonding conductor with a large cross-section or cables with separate double-shielding use, with the screens placed on one side only)
• f) Lay signal and control cables separately from the power cables

In the case of methods and certain fieldbus devices which generally have to be connected or connected to one another via a shielded line, hitherto the interference signals which have been coupled in via the fieldbus connections or other relatively leaky points have been discharged via a metal-grounded slave device housing brought together via a contact strip and connected by means of a connecting cable or a grounding screw with plant ground (functional earth). The use of metallic housings is relatively expensive.

EtherCAT is also based on standard Ethernet technology, offering users the following advantages in particular: In contrast to other fieldbus systems, the process data is no longer received at every component, then interpreted and finally copied. Instead, the data packet is processed "flying". This means that each device reads the data addressed to itself, while the data telegram is already forwarded to the next device. While the telegram is being forwarded, new data can be entered simultaneously. All this leads in comparison to other systems only to a small delay of the data transmission in the nanosecond range and increases the transmission speed.

With field buses and Industrial Ethernet, the communication systems in the production environment are becoming more and more efficient. The components as well as the installation must comply with technical and physical rules, regardless of protocol and system name.

Due to high transmission rates on the fieldbus, high-frequency interference signals are generated in the automation. In addition, high-energy fields are caused by high, fast switched currents of power electronics devices. A consistent shield connection is therefore essential for trouble-free operation. Functional components also provide the required discharge area for high-frequency interference signals. Industrial Ethernet has long since found its way into the industry, resulting in higher transmission rates on the fieldbus. In addition, the advancing automation requires more electronically controlled motors and drives. For example, frequency converters are operated in addition to supply lines and motors in the immediate vicinity of the controllers. Consequently, with technological advances, the electromagnetic spectrum is also changing, increasing pollution by noise. Motors, frequency converters and other devices can unintentionally become transmitters (sources of interference) in industrial environments. In return, controls and controls including the fieldbus may behave like receivers (interference sinks). That's why proper shielding is essential. As a rule, fault-prone signals are routed via shielded multi-wire cables to the system cabinet. On the way there are interfering signals from converters, circuit breakers, frequency converters or other switching operations in the cable shield. However, the further the interference signal shifts into the high-frequency range, the stronger the skin effect becomes. The interference current is in this case forced onto the conductor surface and no longer has the full cross section available. Thus, for high-frequency interference currents, the contact resistance increases at the connection points of the shield support. The components used for grounding therefore have to provide a good conductive surface with simultaneous corrosion protection.

Equipotential bonding for purposes of reducing interference voltage must be made suitable for high frequency and low impedance. This is often made possible by flat connections (strips, sheet metal strips) of metallic system components. A large surface is less important because of the current carrying capacity, but to keep the inductance low. Equipotential bonding rails are used as a ground reference point for electronic controls. There, all ground lines and shields are brought together in a star shape. This is especially important for mixed digital and analog signals. In order to avoid ground loops, ground lines must be routed separately from each other before the ground reference point. For some devices, the device ground is not equal to ground potential. Their reference potentials are floating (undefined) and must not be connected directly to the earth-potential-related ground reference point. These devices or modules must be connected to the other modules via special intermediate coupling stages. The contact surfaces in the housings must be free of grease and dirt. They must not be painted and have no oxide layers.

Before connecting cable shields, the local earth and potential conditions of both support points must be checked. If critical potential differences are detected (fieldbus or plant), suitable measures must be taken by the operator in the sense of the grounding recommendations and / or binding regulations or standards.

Cable shields and steel protection hoses should be placed on both sides, if possible. Previously, the rule was to hang cable shields only on one side to avoid equalizing currents (ground loops).

• a) Stromtragfähigkeit des Schirms überprüfen, d. h. durch Messungen und Berechnungen feststellen, ob der zu erwartende Ausgleichsstrom Schirm und Kabel schädigen könnte.
• b) Ist der zu erwartende Ausgleichsstrom zu groß, um über den Schirm abgeleitet zu werden, muss entweder
• b1) zwischen den unterschiedlichen Potentialen eine stromtragfähige Ausgleichsleitung verlegt werden oder
• b2) eine Seite des Kabelschirms nicht direkt aufgelegt, sondern kapazitiv (10 ... 100 nF bipolar) an den Schirmauflagepunkt angekoppelt werden.

Today, the electromagnetic compatibility (EMC) often requires the opposite, so the two-sided application. Therefore, equalizing currents caused by local potential differences that could destroy the screen, cable and electronics must be prevented or minimized by appropriate measures. For cable lengths over 25 m, the local earth and potential conditions must be checked. If potential differences are detected which can cause compensating currents, the following measures should be considered:

• a) Check current carrying capacity of the screen, ie determine by measurements and calculations whether the expected compensating current could damage the shield and cable.
• b) If the expected equalizing current is too large to be discharged across the screen, either
• b1) between the different potentials a current carrying compensating cable are laid or
• b2) one side of the cable shield is not directly connected, but capacitive (10 ... 100 nF bipolar) can be connected to the shield contact point.

The object of the invention is to improve known devices in terms of their cable shield connection as well as the grounding properties and possibilities.

The object is achieved by certain designs and uses of one-piece, producible by forming a metal sheet locking clamping part for groundable electronic devices. These are especially fieldbus slaves or industrial Ethernet devices as potential-equalizing conductor pieces which can be latched onto a mounting rail and can be contacted with low resistance and which are electrically and / or electrically as low as possible vertical equipotential bonding conductors.

An advantageously combinable variant relates to horizontal equipotential bonding conductor pieces and their applications. By certain configurations and properties of contact eye springs with two or three main contact eyes advantageous, relatively simple and low-impedance cable shield connection devices and corresponding devices can be realized. A variant of the invention relates to a band-like contact eye spring or contact leaf spring with two main contact eyes as a horizontal potential equalization element of a horizontal equipotential bonding to galvanically and / or electrically low-impedance cable shield connection of a connecting device and / or an electronic device by means of two connectable Kabelrundsteckverbinder or two connectable round connector cable.

A further variant of the invention relates to a band-like contact eye spring or contact leaf spring with three main contact eyes as a horizontal potential equalization element of a horizontal equipotential bonding to galvanically and / or electrically low-impedance cable shield connection of a connecting device and / or an electronic device with two to three means Cable round connector connectable round connector cable. The only vertically deflectable contact eye spring is made of spring steel with regard to optimum contact and spring properties.
