  • electrical connector for data transmission must meet special criteria to ensure safe transmission of electrical signals.
  • a modulation method in which a useful signal to be transmitted, the so-called carrier, is changed (modulated). Due to the modulation, the low-frequency useful signal can be converted into a high-frequency transmission signal. The message or the useful signal is recovered on the receiving side by a demodulator again.
  • a modem is installed for this purpose, which modulates the signals for overcoming the connection point as well as demodulates. It is also known to transmit the network signals without contact. For this purpose, for example, light coupling systems or electromagnetic transmission techniques are known. However, these transmission paths are not readily suitable for transmitting security-relevant data.
  • One of the objects of the invention is to propose a plug connection for rail vehicles which ensures reliable data transmission for an Ethernet network.
  • this object is achieved by a plug-in connection, which has at least 1 Gbit / s, eight connection contacts, which are shielded together and paired, and the individual parts of the connector are designed such that the connector has a Steckzyklusfesttechnik of min. 50,000 Has cycles.
  • Plug connections in the sense of the invention are connections which are suitable for establishing a data connection between two vehicle parts of a rail-bound vehicle, in particular a train. This includes connecting a cable to an Ethernet network designed to carry high data rates.

  • the shielding can be made relatively easy and can be ensured as a whole.
  • connection contacts of the plug connection can also be designed such that the plug connection has a plug cycle strength of at least 5000 cycles, in particular 50,000 cycles.
  • a correspondingly abrasion-resistant material can be selected or an abrasion-resistant coating applied to the contact surfaces.
  • the plug element and the socket element can be designed in two parts, so that the worn part can be exchanged when worn.
  • one part each can be an adapter part.
  • This adapter part may comprise a contact connector and a socket for inserting a standard network cable plug or a cable clamp, for directly clamping or crimping the wires of the network cable.
  • the connector may comprise at least one device which causes the adapter part and the male or female part can be assembled only in a certain position or is ensured that only the male part or the female part on a dedicated adapter part fits.
  • the device may be, for example, a tongue and groove guide, also conceivable is a particular arrangement or design of the contacts.
  • the shield of the plug connection can be designed such that its screen attenuation at least approximately corresponds to that of the network cable
  • the housing parts may be made of metal, so that the housing is also the shield.
  • a shield support can be ensured by means of a 360 ° contact brush, which is in contact with the shielding of the network cable.
  • the contacts can also be gold plated.
  • connection contacts can be arranged such that the connection contacts of corresponding cable pairs of the network cable are arranged next to one another and at least the connection contacts of directly adjacent cable pairs are orthogonal to one another.
  • the invention relates to an automatic electrical coupling device for a rail-bound vehicle, comprising at least two plug-in connections, which are arranged such that the vehicle parts are reversible.
