Description

Holder for cut cores The invention relates to a holder for tape-wound cores, especially for a fast, span tapeless assembly.

The advantage of cut tape cores, namely the elimination of any Boxing work compared to normal sheath core sheets is canceled by vmeder the usually very cumbersome assembly of the straps or brackets.

In the previously known arrangements for assembling cut tape cores to tighten the cores, tensioning straps are used, which are wrapped around the individual core and then usually also screwed to a special bracket will.

The advantage of the quick assembly of the cut ribbon core halves around the coil body is lost again due to the cost and time required for assembly.

Wherever there are special demands on the mechanical strength of the bracing of the cut band core transformer is usually placed around the entire outside Core an additional tension band placed.

The invention now allows due to the special strapless Construction, secure assembly in seconds.

As shown in FIG. 1, the bracket consists of a base plate (1), a clamping piece (2). and a head plate (3). The clamping piece (2) is through an opening in the footplate (1) is inserted (see FIG. 2 here). To this end the clamping piece has a bolt (4) and the base plate has an opening (5) for pushing through the Clamping piece. The clamping piece then holds with the bolt firmly in the indentation of the Footplate.

Then, as shown in Figure 1, the lower core halves the cut tape cores are placed on the footplate. This base plate has, as in Figure 2 shown at (6), obliquely bent flaps, which prevent the cores can be pushed away to the outside. The roll is now placed on the lower core halves with the bobbin pushed on. Then the upper halves of the core are put on.

Finally, the head plate according to FIG. 1 can now be put on. As shown in Figure 2, the clamping piece has screw bolts (8) at the upper end, these are inserted through the holes in the head plate (7) and screwed together with nuts.

The top plate has indented protrusions, pressure points or pressure rails at the points designated by (9) according to FIGS. 1 and 2. These are arranged axially to each cut ribbon core. As a result of this axial arrangement of the pressure points, according to FIG. 1, there is a fair distribution of the clamping pressure on the separating surfaces of the cut ribbon core. The warts, pressure points or pressure rails also compensate for dimensional inaccuracies that arise during manufacture. Even with cores of different sizes, the clamping pressure on the individual cores is the same.

By bracing the footplate and headplate with the help of the in the center of the clamping piece guided through the cores can be precisely identified during assembly defined clamping pressures on the parting surface. Q The nuts (11) tightened with the help of a torque wrench However, maintaining clamping pressures is particularly important with the cutting tape core, because of this the hum-free core and to some extent also the losses are dependent.

Wherever with the highest mechanical stress due to vibration or Impact loading requires increased safety, the head and base plate has a Recess (12) for guiding a tensioning strap, which is also around the outside of the core could have been excited.

Claims (1)

Claims to) Holder for cut tape cores, characterized in that the cores are braced with the help of a foot lath (1) and a head plate (3) as well as a clamping piece (p2), which runs through the center of the cores, as shown in Figure 1. 2.) holder for cutting tape cores according to claim 1.) characterized in that the base plate has a recess through which the bolt of a clamping piece is inserted. 3.)
