Claims

The invention relates to a device for replaceable fastening of terminal blocks to a common support rail by means of a one hand against this rail and on the other hand against the terminal supporting spring frame made of spring wire.

Terminal blocks, which are usually next to each other in relatively large numbers on the common Mounting rail are lined up, should not only experience a good hold in the position of use, but also can be exchanged individually, i.e. independently of one another. It is therefore a fastener necessary, which enables each terminal block to be swiveled out of the terminal row.

Such fastening devices are known. However, they have hitherto had the disadvantage that they require too great a manufacturing outlay for their manufacture. This is therefore not in an acceptable relationship to the total price of the terminal block

men, which, as is well known, are downright mass-produced articles

are. In addition, the known fastening devices because of their components have such dimensions have that they can no longer be used with small terminal blocks for reasons of space. One known terminal block has z. B. a curved leaf spring for clamping on the support rail. That Flat material used to manufacture the leaf springs can easily break or tear when bent, see above that rejects arise.

It is therefore the object of the invention to provide a fastening device which the interchangeable definition of the terminal blocks on the mounting rail in a simple manner that allows the Clamps reliably holds in the position of use, which is easy to manufacture in terms of manufacturing technology, and therefore cheap to manufacture and which can also be built so small that it can be used even with small terminals.

According to the invention, this object is achieved in that the spring frame made of spring wire is bent L- shaped and has two crossbars, one of which is interrupted and engages with its ends in opposite holes of the series Kletnnu ', while the other continuous crossbar in a groove the terminal block slides.

A fastening device according to the invention is characterized by its simple structure and its inexpensive manufacture. All you have to do is bend a piece of spring wire into a frame and angled it around an ouerliiiie. Because of its Fedei effect and because it is captive on the terminal, this frame offers the terminal a reliable hold on the mounting rail. On the other hand, the clamp can easily be swiveled out transversely to the mounting rail for replacement, with the spring frame on the above-mentioned longitudinal surface of the row fastening device
