Description

Arrangement for fastening spring strips

The! Inflation relates to subracks for the message and information technology, and in particular those in which the assemblies in small format on a circuit board are constructed with a printed circuit. The subrack is here to accommodate the circuit boards with guide rails equipped, which are attached with their grooves facing each other on cross members and an insertion of the circuit board in the rack. Spring strips are attached between the guide rails, over which the inserted Printed circuit boards are electrically connected.

In the known arrangements of this type, two with the insertion grooves facing each other and for insertion a printed circuit board serving guide rails together between cie upper and lower cross rails from the front of the Subrack pushed and attached to this in a suitable manner. During this process, mostly .in recesses of the guide rails with the ends inserted, the associated spring strip pushed in and form-fitting and force-fitting held in this position

The disadvantage of this design is that when mounting in difficult way three items must be held and at the same time brought into their intended position.

The object of the innovation is to avoid this disadvantage.

In the case of an arrangement for fastening spring strips in subracks, in which guide rails for receiving printed circuit boards are attached and the socket strips for connection of these circuit boards * ·, are used for the news and informatiXBi technology, this is achieved according to the innovation in that after the two have been attached, their guide grooves face one another Guide rails for the circuit boards between approaches The socket strip inserted into the guide rails is secured in the installation position by at least one inserted wire - '' who lays behind the approaches of the components or at least

penetrates one of the components. This design makes assembly much easier, since first of all the one guide rail, then the other guide rail and finally the spring strip can be attached individually.

A particularly advantageous structure of this arrangement is achieved in that the wire penetrates an opening in the spring strip and engages behind the approaches used to guide the spring strip. It is also planned that !? a wire to secure In each case a row of spring strips is attached. Appropriately the socket strips are secured by a wire at each end.

An embodiment of the innovation is shown in the drawing.

Cross rails 1, 2, 3 and 4 are fastened in a subrack 5, & it is shown in perspective in the view from the rear. These cross rails are provided with a grid in a known manner and allow the attachment of guide rails with a selectable distance. In each case two guide rails 6 and 7 are attached to the cross rails 1 to 4 with their grooves 8 facing one another. Each of the guide rails 6 and 7 is provided at its rear end with two extensions 10 and 11 running in the longitudinal direction and one extension 12 running transversely thereto.

After the guide rails 6 and 7 have been attached to the cross rails 1 to 4, a spring strip 13 is introduced from the front of the rack, which by the approaches 10,11 and 12 receives the desired installation position laterally and to the rear. To secure in this Linbaulage, especially against falling out to the front of the subrack, the socket strips are secured by wires 14, 15.

For this purpose, the spring strips are provided with openings 16 and 17, respectively provided and the wires 14 and 15 respectively are from the side of the construction group carrier inserted in such a way that they penetrate the openings of the spring strips and between the lugs 10 and 11 on the one hand and the lugs 12 on the other hand.

Appropriately, each wire 14 or 15 in its length dimensioned so that it secures a number of spring slats in their position. The inserted wires can be pushed open at their ends Wear sleeves.

One fully inserted into the grooves 8 of the guide rails 6.7 Circuit board 9 is then electrically connected via the associated spring strip 13.

Claims (4)

_ * _ RA. 019 657 * 14.1.65 Protection claims 1) Arrangement for fastening spring strips in subracks, in which guide rails for holding circuit boards are attached and the socket strips are used to connect these printed circuit boards for communications and information technology characterized in that the guide rails facing each other with their guide grooves (8) after the fastening of the two (6,7) for the circuit boards (9) between lugs (10,11,12) of the guide rails introduced spring strip (13) through at least an inserted wire (14 or 15) secured in the installation position is, which lies behind approaches (10,11) of the components (6,7,13) or penetrates at least one of the components. 2) Arrangement according to claim 1, characterized in that the wire (14 or 15) penetrates an opening (16 or 17) in the spring strip (I3) and behind the approaches (10, 11) serving to guide the spring strip (13). 3) Arrangement according to claim 1 and 2, characterized in that a wire (14 or 15) to secure a row of spring strips (13) is formed. 4) Arrangement according to claim 1 and 2, characterized in that the Spring strips (13) at each end through a wire (14 or I5) are secured.
