( Arrangement for connecting electrical conductors

The innovation relates to an arrangement for connecting electrical conductors with a terminal block with Is equipped with tabs having flat plug connections.

In the new concept of electrical installations (merging and connecting include electrical conductors, one A sets usually to a specific type of connection established, that provides, for example all terminal connections or screw or solder terminals or quick connect terminals before. Like

dazed type of connection, especially with so-called jumper distributors, where fast handling is required arrives is the blade terminal. In the redesign it is then assumed that everywhere vfo required to have terminal blocks with plug-in lugs the flat plug connections. The conductors to be connected here are then provided with flat receptacles, which can be put on the flags. The problem here is that such flat plug

However, this is only possible with finely stranded conductors with a smaller cross-sectional area.

The problem now lies in the fact that the manufacturer of such an electrical system is in his Conception to a certain type of connection can determine that the user of the system, who yes on his part then has to connect certain units to the system via electrical conductors, by no means always and in any case the use of the conceived type of connection is possible or at least inexpensive is. One must therefore in a complicated manner when redesigning the system on the part of the system manufacturer from the outset, if possible, take into account the wishes of the user and you can see then inevitably several types of connection before, which makes the design of the system is made more difficult and in particular the stockpiling of several types of connection systems and associated Terminal blocks is required. Nevertheless it happens again and again that either due to insufficient Coordination or later change of conception sees the user facing the big problem in the system to find a type of connection that is extremely unsuitable for some of its conductors to be connected is or is not usable at all, so that changes are required, which are all the more so for the user are more problematic than not being allowed to resolve the wiring made by the system manufacturer himself, if he wants to keep warranty claims.

The present innovation is now based on the object of an arrangement for connecting electrical

To create a ladder of the generic type which, on the one hand, enables the system manufacturer to create a uniform, to create a concept that is easy to implement and, on the other hand, it for the system user enables this basic concept to be applied and maintained without any problems even if in one or the other other case the conductor to be connected to him is unsuitable for the given blade terminal.

The solution according to the innovation consists in an adapter,

It is essential that, in addition to closing the electrical contact, the generation of a sufficient holding force for the adapter on the blade terminal of the series

Further refinements of the subject of the innovation are characterized in the subclaims. To be highlighted is in particular the structurally particularly simple design of the holder in the form of the adapter housing located locking pin.

An embodiment of an arrangement according to the innovation is described below with reference to FIG Drawing described in more detail.

The drawing shows an arrangement according to the innovation, consisting of the terminal block with flat plug connections and an adapter placed on one of the flat plug connections with the housing cover removed.

The arrangement initially included a commercially available terminal block, in its insulating housing 1, the a foot 2 for snapping onto a standard mounting rail comprises, flat plug connections 3 are provided on both sides, each having four lugs 4. the Blade terminals and the flags have the usual construction, with the 4 in. Near the free end of the flags these holes 5 are provided.

The arrangement also includes an adapter 6, in the housing 7 initially a connector 8 for the to be connected conductor is provided. In the illustrated embodiment, a screw connection 8 is shown. By its very nature, however, the adapter can also

contain another type of connection, for example a clamp connection or a solder connection, or else again a flat plug connection, but now in a completely different size range than the corresponding one Flat plug-in connection of the Reinenklenune, to that extent too to enable adaptation. In the housing of the adapter is also in an electrically conductive connection with the screw connection 8 a current transmission part 9 is arranged, which carries a contact 10 which is connected to it. suitable and designed to be on one of the flags

4 of the affected blade terminal 3 of the terminal block.

In order to ensure that the adapter 6 in its entirety is now properly and securely seated on the blade terminal 3 to give the terminal block is also at least one holder of a non-electrical type in the adapter housing arranged, which engages with a further lug 4 of the blade terminal 3 when the adapter is attached stands. In the illustrated embodiment, two such holders are for this purpose in a very simple way in the form of locking pins 11 provided in the holes

5 of the two affected lugs 4 of the blade terminal 3 are formed in a corresponding spatial position on the adapter housing 7 and inserted into it. When the adapter is in place, these two locking pins 11 enter the holes 5 a little and ensure a good, secure hold on the flat connector. Further locking pins 12 provided on the adapter housing 7 are used to snap on a cover that closes the housing 7 (nichtdarge represents).

The adapter shown is single-pole. It goes without saying that an adapter can also have multiple poles with a corresponding series of connections.
