Abstract

Electrical plug connection with a first plug connector part - in particular a plug part (1) and a corresponding second plug connector part - in particular a socket part (2) - with electrical contacts that can be fitted together, the plug connector being provided with a coding mechanism designed to prevent incorrect wiring by fitting together non-corresponding plug connector parts, is characterized in that at least one of the plug connector parts (1, 2) has a wirelessly addressable RFID-Tag (6) as a coding device, wherein on the corresponding plug connector part or on a housing, on which the corresponding plug connector part (1, 2) is arranged, there is arranged at least one device (8) for receiving the data transmitted by the RFID-Tag (6).

Description

The The invention relates to an electrical connector according to the preamble of claim 1 and a method according to claim 9.

Out The prior art plug connections are known which together have to be connected electrical contacts that in the field of automation technology depending on the type of bus standard used, different contact or have pin assignments.

Around to prevent connector parts for different bus systems accidentally put together, it is known the connector parts to be provided with geometric features (for example with bars) one of the connector parts and corresponding recesses on the other of the connector parts), a mating does not of related Prevent connector parts.

in this respect the known state of the art has proven itself. It but is desirable, the generic plug connection in such a way that a further security against faulty circuits guaranteed becomes.

The solution This problem is the object of the invention.

The Invention solves This object is achieved by the subject matter of claim 1. It creates In addition, the method of claim 9.

advantageous Embodiments are to be taken from the subclaims.

To The basic idea of the invention is at least one of the connector parts provided with an RFID tag (RFID: = Radio Frequency Identification; in the German technical literature also radio detection or radio detection module called, preferably a transponder and a transceiver unit contains and in a parent Data processing system is integrable to the data on the To process the day), in which data is stored or storable, that of a corresponding receiving unit on the corresponding connector part are readable, which in the case of a mating incompatible Connector parts directly on the connector or on a parent Data processing unit is issued a warning.

To a development of the invention, the connector parts are characterized the connector characterized in that before, at or after the contact closure the electrical contacts of the two connector parts at a first mating of the one connector part in the RFID tag the second Steckerbinderteils information - in particular a data address - written be stored there. If the connector is loosened later - e.g. for maintenance or Reparaturarbeiten-, is so before or after a renewed Plug in verifiable, if the pre-stored address of the connector part to be contacted correct is. You can Misconnections after maintenance and repair work especially be largely avoided.

In addition, more extensive Information should be stored, so type and type of to be used Connector as well as other data.

following The invention will be described with reference to the drawing based on embodiments explained in more detail, wherein Also, other advantages of the invention will become apparent. It shows:

1 a perspective view of a connector part partially shown in an exploded view and a female part of a first connector according to the invention;

2 Plug connections to a distributor housing; and

3a , b is another perspective view of the arrangement 1 and an enlarged view of the areas of the mating faces of the two connector parts. and

4 a perspective view of a connector part partially shown in a blasting view and a socket part of another connector according to the invention.

1 to 3 each show plug connections with a first connector part - a plug part 1 - And a corresponding second connector part - a socket part 2 ,

To 1 are the plug part 1 and the female part 2 each formed in an advantageous manner as RJ45 plug and socket part, each in a belonging to the connector one or more parts here plug adapter housing 3 or a female adapter housing 4 can be mounted in order to use the designed itself for an office environment connector parts in harsh environments, such as in the field of automation technology.

Such an application shows 2 , Here are several of the plug connections on a distributor housing 5 arranged, with the bushing parts 2 with the adapter housings firmly attached to the distributor lergehäuse 5 are pre-assembled, and where the connector parts 1 are designed with their adapter housings for connection to a cable (the latter is not shown here).

At least one of the connector parts 1 . 2 has a wireless addressable coding device, which is designed as a radio frequency identification (RFID tag 6 ) is trained.

Here is the RFID tag 6 each example of the adapter housing housing 3 of the plug part 1 arranged, wherein the corresponding connector part - here the socket part 2 - At least one receiving device 8th or a combined transmitting and receiving unit, with which it is possible, at least data from the RFID tag 6 to query and preferably also data in the RFID tag 6 to write. For data and possibly energy transmission with the RFID tag 6 can each at this and possibly the corresponding connector part inductances 9 different design (see 3 or 4 ) on the plug part 1 and at the socket 2 be arranged.

To 1 to 3 are the inductors 9 each around the adapter housing 3 . 4 while wrapped after 4 printed inductors 9 be used on a slide.

The corresponding connector part - here the female part 2 Or a superordinate control device connected thereto are designed in such a way that either an individual designation or address into the RFID tag occurs during or after the initial installation 6 of the connector part 1 is written, which is later sent out of this again or is queried and / or that at least in the RFID tag 6 query pre-stored information and can be transmitted to a higher-level data processing device, which stores this information.

In this way, it is possible to ensure in a simple manner that only associated connector parts are connected to one another, since in the case of a faulty circuit, a warning, for example, to an LED 7 is shown.

In addition, in the case that the RFID tag 6 of a connector connector part 1 is writable from the other connector part, possible to assign the connector part an individual address and store it in the connector part.

Misconnections after a maintenance case can be safely avoided in this way. That it is advantageous if such a faulty circuit excluded who can, illustrates 2 , which provides a tight arrangement of the connectors on the distributor housing 5 disclosed.

It is also conceivable that both of the connector parts of a connector RFID tags 6 have (not shown here).

For reasons of space, it makes sense to use the RFID tags 6 , the display device 7 and the device 8th each at the adapter housings 3 . 4 to arrange.

In terms of handling, it is advantageous if the errors are already detected and displayed in advance of the closing of the electrical contacts, so that the display device (LED 7 ), for example, even before the mating of the two connector parts 1 . 2 shines.

Is this one of the connector parts on a housing - eg a distributor housing 5 - Arranged, the transmitting and receiving unit 8th with which the data is written to or retrieved from the RFID tag, also on this housing 5 be arranged.
