Definitions

  • the invention relates to an automation system, comprising an automation device with a first connection element arranged in a housing for connection to a data line.
  • Data communication within automation systems or from one automation system to another automation system is increasingly carried out via a fast data connection with a high data rate, for example via Profinet, which represents Ethernet technology within the automation technology.
  • automation devices such as programmable logic controllers, interface modules, distributed peripherals, sensor modules, etc. have corresponding data interfaces.
  • Ethernet in automation technology ie an Industrial Ethernet
  • the operation of such an Industrial Ethernet especially in harsh environmental conditions for automation devices, increasingly problems.
  • the wiring and especially the sensitive connectors are exposed to high mechanical, climatic and chemical stresses in harsh manufacturing environments. For this purpose, particularly reliable connection techniques that ensure the necessary network availability and transmission performance required.
  • jacks according to the RJ45 standard are used for connecting data lines.
  • various connectors with the RJ45 design are already in use in automation systems in industrial environments.
  • An industrial suitability of such RJ45 connection refers only to the RJ45 connector and does not refer to the Connector plug-socket or the socket itself.
  • a connector according to the RJ45 standard provides generous tolerances in the plug-in area of the sockets, so that both a guide behavior for the plug and a locking of the same for industrial environment with mechanical loads, in particular vibrations, unsuitable is.
  • industrial grade sockets with improved contact system and an optimized shield connection change nothing to this basic problem of the standardized RJ45 connections.
  • the data cable which is adapted to the connector, mechanically attached to an automation assembly in the vicinity of the plug.
  • This attachment is realized for example by an additional cable attachment by means of a cable binder on the automation device.
  • a swinging of the plug can be reduced, but a release of the contacts within the plug or a destruction of the gold layer, which is applied to the contacts, not be permanently avoided.
  • These errors cause data link failures.
  • this failure behavior can be improved by the use of standard patch cords from the non-industrial environment, since they are less burdened by their much lower mass vibrations. However, this does not guarantee other aspects that are important for industrial use, such as good manufacturability or good electromagnetic shielding of the connection.
  • an automation system with an automation device and a Provide port for connection to a data line that accommodates the harsh industrial demands and reduces a failure rate of the data links.
  • an automation system comprising an automation device with a housing arranged in a first connection element for connection to a data line, wherein the first connection element is disposed within the housing, that it is surrounded by a receiving means, an adaptation means with a second connection element wherein the adaptation means is configured such that a detachable connection with the receiving means is formed and a movement of the adapter means is prevented by the receiving means, wherein the first connection element engages in the second connection element for electrically connecting the adapter means with the programmable controller, further comprises the adaptation means a connecting means, which is designed to connect cores of the data line thereto, wherein a means for signal transmission is arranged between the connecting means and the second connecting element.
  • the data line is now adapted via an adapter, which can be designed as a plug-in adapter, directly to the respective automation system.
  • a fault-prone connection point via an RJ45 plug-socket connection is thus bypassed.
  • the releasable connection can be formed non-positively, positively or as a combination of the two.
  • the connection is designed as a form-fitting because of plug security, it is important that a relative movement between the adapter and the receiving means is prevented.
  • the means for signal transmission can be designed as a printed circuit board or as electrical connecting pins, preferably it is designed so that air and creepage distances are optimally designed for currents between the signal pins.
  • the connecting means is designed as a cutting-clamping device for the wires of the data line.
  • the receiving means and the adaptation means preferably form an interference fit, wherein these two connection partners or the first connection partner, which constitutes the receiving means, prevents the second connection partner, which represents the adaptation means, from moving.
  • the receiving means may preferably be designed as an integral part of the housing, and thus can absorb the adapter, which is configured for example as a plug-in adapter, vibration-proof and low-vibration.
  • wires are protected, corrosion and vibration safe in the insulation displacement terminals.
  • a connection of wires of a data line via an insulation displacement device forms a gas-tight, permanent, electrical connection.
  • an installer saves time with this connection technology and also creates reliable data connections with regard to the electrical properties.
  • a long-term stability of the connection and a contact security are no longer dependent on the skill of the installer.
  • the tedious stripping processes of the wires are avoided.
  • loose small parts such as e.g. Fixing screws are unnecessary.
  • the adaptation means has a noise suppression means for reducing electromagnetic incompatibilities.
  • These interference suppression means may for example be designed as a ferrite ring core or constructed as a termination network for the data line comprising resistors and capacitors or inductors
  • the adaptation means Shield element for connection to a shield conductor of the data line.
  • a secure ground connection of the data line via the screen element with the adapter ensures the suppression of interference and thus increases data security.
  • a line piece is connected to the connecting means with a first end and at the second end of the line piece a socket for receiving a data connector, wherein the socket is surrounded by an elastic sheath.
  • the line section which represents, for example, a patch cable, that is to say a short data line, is firmly fixed with its respective data wires via the insulation displacement device to the connection means.
  • a cable adapter is provided with the adapter and the permanently connected line piece.

  • This cable adapter part can be adapted to the connection means as required or be solved by him.
  • the elastic sheath designed as a vibration protection encloses the RJ45 connector, which can also be laid in a cable duct depending on the nature of the cabinet, for example, for additional protection. Due to this configuration of the connection of a data line to the automation system, a mechanical load on the connector RJ45 is reduced, because the mechanical load, which is usually coupled via the automation device to the connector is due to the geometry of the structure so the greater distance of the sensitive RJ45 connector reduced to the mounting point of the device.
  • the adaptation means has additional fastening elements for further connection to the receiving means or the housing.
  • This extra Fastening means may be configured, for example, as a screw connection, in order to increase the contact pressure of the connection elements arranged in the adaptation means and in the receiving means, which are configured, for example, as plug connectors, and thus further increase the contact reliability.

  • the cores 50 can thus pass on their signal currents via the circuit board to the second connection element 2, which is also arranged on the circuit board via the insulation displacement device.
  • the second connection element 2 transmits the signal currents to the first connection element 1, and thus the signal currents reach the printed circuit board 91 of the programmable controller 90, in which they can be processed.
