Electrical connection block

The invention relates to an insulating block for attachment to a support rail, which has a pair of elastic, with Has locking lugs provided fastening legs.

In Europe, customers are required to be able to mount electrical connection blocks on a mounting rail that conforms to DIN standard 46277, which defines a rail with a U-shaped cross-section, one leg of which is longer than the other and the leg ends of which are bent over so that as a result, the open side of the U formed is narrowed in a stepped manner. ^:: -

Other types of U-shaped rails are also in use, which have legs of the same length. In some applications, connection blocks are provided with bulges, which form a sliding fit within the rail. However, the assembly of these blocks is from one end of the rail

necessary. Another application uses the blocks provided with spaced apart elastic feet that can be resiliently attached in the rail, so that the Block is held releasably. Experience has shown that it is difficult to mount such blocks in the rail without additional fasteners to hold on.

An insulating block according to the invention is featured in that the fastening legs convergent Have parts that are connected to one another by a strut.

In use, the legs can be between the bracing and the block are bent towards one another so that the locking lugs are brought into the rail past the edges of the opening can be until the bracing to the base of the rail profile abuts, whereby the bracing is aligned and forced the hasty noses outwards will. As soon as the snap noses are below the rail edges have arrived, they snap under the elastic effect the leg to the outside, this process being significantly supported by the bracing. In the final state the ITases snap in firmly below the edges of the U-shaped Rail and hold the block firmly in the rail.

Further features and advantages of this novel fastening mechanism are described in an exemplary embodiment in conjunction with the drawings. In the drawings show: '

FIG. 1 shows the cross section of a connection block which is fastened in a support rail;

Figure 2 shows a series of successive positions when inserting the block into the rail in a similar view.

The block. 1- ordered from elastic "insulating material, z» B »nylon, and is provided with passages for electrical connections. A lower edge of the block is provided with a downwardly projecting projection 2, which has a shoulder surface 3, which with the end 4 of the shorter leg of the U-rail cooperates, / while a higher shoulder surface 5 of the block cooperates with the end 6 of the longer leg of the U-rail.

A pair of legs 7, S run down from the block 1 at a distance corresponding to the width of the opening of the rail.

The strut 12 and the legs 7 and 8 are relative to the U-rail dimensioned so that in the shown Position the strut 12 in the relaxed state lower than the G-round surface of the U-rail would be; corresponding is the distance between the contact surface of the locking lug 9 and the adjacent end of the strut in the relaxed state 12 in the direction perpendicular to the strut greater than the distance between the edge 4 and the base of the U-rail.

During the introduction (see Pig · 2) the nose 9 is under the edge 4 is pushed, and the block 1 is pushed around the edge 4 rotated clockwise so that the strut 12 is pressed against the base of the U-rail. The further movement bends the part 11 of the leg 7, and at the same time engages the edge 6 on the underside of the locking lug 10 and moves the block to the left, causing leg 8 to bend will.

Once the latch 10 is released from Oer edge 6, it is driven by relaxation of the leg "8 outwardly and in the same way the strut firmly against the base of the OB rail compressed. This type of fastening guarantees a significantly improved stability ₀

If the block is to be released again, a lever is used, ζ.
