Abstract

The plug connector has a number of contact elements accessible from a connector side and a number of conducting rails which connect groups of the contact elements on the other side. The contact elements are socket elements (13-15) arranged in several rows, of which some (13,14) are arranged in a first group of holders (33,34) and some in a second holder (35). The first group of holders are designed for direct connection to a number of multiple pole plugs (61). The second holder is designed to hold a single adapter element (71). The sockets are arranged in three parallel rows in the first group of holders, with each three adjacent sockets connected by a conducting rail.

Description

The invention relates to a multi-pin connector for Potential distribution, with a plurality of contact elements, which are accessible from a connection side, and with a number of conductor rails, one on each opposite side Connect a subset of the contact elements to each other.

A connector combination is known from EP 0 254 385 A1, each with two 36-pin on a base plate Micro plug combined as pin plug or as socket connector are. There are special grounding contacts between the contacts intended. A potential distribution between the Plug contacts of the male connector or the female connector are made Not.

A multi-pole plug insert is known from DE 93 02 091 U1, in which a plurality of socket contact elements each connected to two terminals via branching conductor rails is so that the potential of each connector to be made can be fed to two consumers. The production the clamp connections are cumbersome. The branch the potential of a plug connection on two terminal connections does not meet all practical requirements.

It is already provided with this connector, bridge contact elements between two conductor rails, to the number of assignments of a plug contact increase. The number of usable plug contact connections with different potential is reduced accordingly if use is made of the possibility of connecting bridges.

Proceeding from this, the present invention has the object to create a multi-pin connector in which the desired connections for potential distribution using Plug contacts can be made. Here, however, should the possibility of plug connection with mating plugs different Types - pin contacts or socket contacts - covered become. Plug contacts should be manufactured in groups are.

The solution to this is that the contact elements in are arranged several rows of socket elements, one of which Part in several first recesses and part in a second Recess are arranged that the first recesses for direct connection to a plurality of multipolar in each case Plugs are identical to each other and that the second recess for receiving a single adapter element is formed differently from the first recesses, and that the connector is a first plate-shaped element with mutually parallel cylinder bores into which the Bushing elements are used and that is the first recesses and the second recess in a parallel arrangement comprises that the connector has a second plate-shaped element includes, which lies flat on the first and in the adjacent Surface has recesses in which the conductor rails lie in, and the one with the second recess of the first Has element cover in recess, and that in the recess of the second element is a supplementary part with the additional sockets or an end cover is used.

This provides a connector, in particular in the field of rail vehicle cabling but also in the Mechanical and plant engineering cabling the entire cabling can significantly simplify by using this only Plug connections is shown. Instead of diverse connection systems with crimping, screwing, clamping and other connection techniques within a wiring that covers the entire Control technology as well as lighting can now be included uses the connector technology. Here are preferred Uniform pin and socket contacts in the form of turned parts used in the connector frame or connector housing just snap into place.

Due to the different design of the first and second Cutouts stand for the exit side in the first cutouts, d. H. for connecting several consumers on one Potential, socket contact elements immediately available, while for the input side due to the applicability of Adapter elements in the second recess the choice between Socket contacts and pin contacts as connection options consists. This applies both to the simple design Attachment on the wall with a closing cover element on the back, where only the connection of the sockets of the first recesses each with a row of sockets for the second recess Potential distribution is possible, as well as in the preferred Version with a supplementary element with additional sockets the back, where it can be inserted into a housing wall have to be. Here, the other contacts on the Back can be used as an input and on multiple output contacts, in particular distributed over three output contacts for a group of outputs Choice of using socket contacts or pin contacts consists.

Depending on the type of consumer, one may need to Plug connection of a combination of plus, minus and signal line easy to manufacture, or for a plurality of like ones Consumers, for example in the area of lighting, Establish connection at the same potential. For this are in preferred version connector proposed, the connector frame have three three-pin single plugs can, whereby by providing two different connector frames, which are coded unmistakably by the shape and which can be distinguished by different colors, the individual poles of the three-pin connector with each Sockets on conductor rails of different potential or with sockets lying on a common conductor rail, get connected.

The connection of the socket contact elements with the conductor rails can be done by soldering or riveting.

As the exemplary embodiments show, the variation of Conductor rails also connect four or five socket contacts possible at the same potential, without the possibility to make use of the bridge connections. This possibility occurs, whereby - as known from the prior art - however the number of different available Potential is reduced.

For certain previously known, repetitive applications The contact inserts can be used for cabling situations also different over the length of the recesses with conductor rails Type are equipped, where necessary to save. individual through openings are not equipped with contact sockets Need to become.
