Description

Description:

The invention relates to electrical connection and / or connection terminals, in particular Terminal blocks with detachable jumpers for electrical connection on top of each other like floors arranged terminals, each jumper is designed in one piece and contact legs has that electrically connect the busbars of the stacked terminals with one another.

Clamps arranged one above the other in the manner of floors are known as vertical clamps and as so-called Floor ski names known. The stacking clamps are usually independent individual terminals each with their own insulating housing, which through Putting on and locking the insulating material housing into storey-like structures one above the other Terminals can be increased. In the case of the so-called Floor Skieramen, such as. B. Double level terminals or three-tier terminals, these are usually terminals that are in a common Insulated housing are housed.

For the Aufstockklemmen Aufstockbrücker according to DE-OS 27 36 664 are known, the two in have opposite direction extending contact legs. By means of this docking jumper Only two floors arranged one above the other can be bridged. You need to

be positioned before adding the clamps and a later bridging is only after prior dismantling of the extension clamps possible * The aforementioned floor clamps, the have a common insulating housing, cannot be bridged with such extension jumpers will.

For floor terminals with a common insulating material housing, screwless, detachable ones are used Brücker not known. Here you can make do with a screwable bridging device z. B. in such a way that a screw is guided in a threaded piece of the upper busbar and is screwed against the floor level lower power rail. Here, too, are only two superimposed Floors can be bridged and there is also the disadvantage that the said screw tension forces between the superimposed Generated busbars that have to be absorbed by the straight insulating housing.

The object of the invention is to provide a detachable jumper for storeys on top of each other to develop arranged terminals that are universal, also for more than two floors and independent the type of clamp can be used as an extension clamp or as a floor clamp.

This object is achieved according to the invention in that the busbars are arranged one above the other Clamping in a known manner in a vertical direction

seal aligned plug-in recesses own and that all contact legs of a bridge starting from the head of the bridge in a Point in direction and one after the other corresponding to the distance between the plug-in recesses of the individual Busbars are arranged from each other.

The bridges according to the invention are subsequently installed from above in stacking clamps or floor clamps plugged in and they bridge two or two, depending on the design of the terminals and their contact legs “More floors. They can easily be pulled out upwards again, i. H. solvable, whereby it is expedient can be to design the head of the bridge as an insulating head with appropriate handle recesses.

A particularly advantageous embodiment of the Invention provides that the plug-in recesses of the busbars are made rigid and that the contact legs of the jumper are designed to be resilient. Of course, the reverse is also true Case useful in which the plug-in recesses have resiliently yielding contact edges ♦

With regard to the structural design of the bridges according to the invention is one embodiment preferably, in the case of the laterally resilient contact leg on a rigid support leg of the jumper are arranged. Such a jumper is particularly suitable for bridging more than two floors.

line is another useful embodiment of the The invention provides that two laterally resilient contact legs of the jumper at least one after the other two plug-in recesses of the busbar reach through, the contact legs in one each assigned to a plug-in recess Contact shank areas are divided, which are designed to be resilient relative to one another.

Further details of expedient embodiments of the invention are given by way of example the drawings described in more detail. Show it:

Fig. 1 shows the side view of a double-decker terminal with an enlarged floor bridges shown according to the invention,

2a-c exemplary embodiments of stock

work bridges.

The two-tier terminal shown in Fig. 1 has a common insulating material housing 3 with two through terminals. The lower through terminal with the busbar 4 has the two ends Cage clamp connections 5 and 6. The upper through terminal with the busbar 7 has the two cage clamp connections 8 and

According to the invention, the busbars 4 and 7 of the terminals arranged one above the other are provided with plug-in recesses 10 and 11, which are aligned with one another in the vertical direction. Used for bridging

the jumper shown in Fig- 1 with an upper head 12 of insulating material and pointing in a) direction of contact legs 13 and 14. The contact legs are individual respectively the · plug cavity divided 10 or 11 associated contact leg portions 15 and 16, wherein the contact leg portions relative can spring to each other.

When inserting the floor jumper, the contact leg areas 15 first contact the Plug-in recess 11, the stops 17 and 18 come to rest on each other »Then contact the contact leg regions 16 the plug-in recess 10, the contact leg regions 16 around the Stops 17 and 18 can spring. In this way, both in the plug-in recess 11 and in the plug recess 10 achieves a good electrical contact connection.

2a - 2c show other possible embodiments of a floor bridge according to the invention, which is shown again with a head made of insulating material.

The floor bridge according to FIG. 2a has a inherently rigid support legs 19 with laterally arranged resilient contact legs 20 and 21. It Ιίβς It is obvious that this embodiment of a bridge is particularly suitable for multi-level bridges.

The floor bridge according to FIG. 2c also has a stiff central web 27, from which again two contact legs 28 and 29 or 30 and 31 extend, but in comparison in the opposite direction to FIG. 2b, starting from the supporting end of the central web 27.
