Description

The invention relates to a siirnkontak-

oriented capacitive network, in which a staggered one on top of the other coatings and dielectric layers Containing layer or stack capacitor through cuts in several electrically conductive connected Teilkonde.tsatoren is divided. Under fur there is an interconnection of passive two-pole (ohmic resistances, capacitances, inductances), three-pole (triodes) and Four-pole (mesh decouplers) and the like. Under a capacitive network, the interconnection

switching of capacities can be understood.

Such a network rt from the Swiss Patent specification 22 ° 055 known. It consists of several parallel condensers and is referred to there as a "decoupled capacitor".

Through the incisions in the capacitor, the resistance of a regenerable capacitor should be created increased vein. A selectable interconnection von Teilkondeusaiorcn is in a structure according to the named patent is not possible.

From US Pat. No. 3,235,939 is genial. '. Figs. II to I (i a on the basis of a ceramic capacitor * established capacitive network known. This is different due to the imprint Shaped areas of the covering on ceramic plates, which are then stacked exactly on top of each other must be produced, so requires a great deal of effort in production.

U.S. Patent 3,304,475 is a Ceramic capacitor with an internal series connection of partial capacitors from Fig.fi known, in which the coverings by insulating strips are divided and covering parts lying on top of each other with different potential overlap. Such a capacitor also represents a special case of a capacitive network. It can be however, also only produce with great effort, since each of the covering areas on each individual Capacitor plates must be made for themselves.

The object of the present invention is to provide the capacitive network described above to train so that each of the partial capacitors can be kdiitaktiert for itself, and thereby one To enable selectable interconnection of single-wire interconnected partial capacitors.

This makes this task edindimustiemess loosened, (. let the incisions run across the sides. »11 to whom one behm over the other Surface protrudes that they are at least over the total width of the coverage area of the opposite polarity Coverings extend and that selected covering edge areas corresponding to the desired circuit are provided with connections.

The invention shows a way. how aiii A capacitive network can be accommodated in the smallest of spaces. With the help of the invention it is possible to connect in series a large number of capacitors for high DC or AC voltages.

B. can cause difficulties with series connections, lets you see Carry out this on each individual capacitor, as the individual linings of each partial capacity are accessible from the outside are.

In the! · 'Ι μ. The incisions extend alternately against each other. The egg grooves 3 and 5 equalize from iLt the same stump surface and the incision 4 in between starts from the opposite end face. If there are layers of conflict on the end faces of the exit condenser, these are sinile; they run through the edges of the incision. The toppings are mi conical. that a series connection according to the I i <j. 2 results. The free coverings of the two external capacitors I and IV of the output capacitor with the external power supply elements α and /> are blinded. Since the incisions 3 and S essentially only extend over the width of the outer cover area and possibly only extend beyond it to a small extent, the coatings of the external capacitors with opposite polarity to the free coatings are included over the connecting stretches F and 7 of the sheets tied to partial capacities II and III. This creates a series connection of the partial capacitances I to IV shown in FIG 2 way shown rear other. The parts ("and 8 are isolated from each other and the part 8 is thus isolated from the connections" and b . In the case of end contact layers, this can be done by applying the end contact layers before the incisions are made, and separating and isolating them when the incision is made.

The arrangement shown in FIGS. 1 and 2, respectively can z. B. as inductive: use an effective capacitive voltage divider. DaIn i can use the removed Measurement voltage can thereby be adjusted more easily to the desired amount that a Partial capacity is chosen to be larger, for example when making the incisions. As a consequence of this the voltage tapped on it becomes correspondingly smaller.

In FIG. 3, the incisions 3, 4, 5 extend from the same end faces. Extend the incisions at least over the upper cover area of coverings 1 and 2 and can be around a extend a small amount beyond the same. The partial capacities created in this way I. II. III. IV are via the non-incised connecting piece 6 of the covering 1 in that shown in FIG Way connected. The section 6 is in contact with the outer connecting element a. The connecting piece of the covering 2 lying outside the capacitively effective area is of the Incisions 3, 4. 5 severed. By interposing of resistors and inductances and other electrical components between the connections of the partial capacities, any switching connections and networks can be achieved will.

In Fig. 5, the two incisions 3 and 4 extend over the Überdicckungsbercich of the two layers 1 and 2. This results in the partial capacities 1, II. III. The partial capacities are connected to one another via the non-incised connection area 6 of the floor 2. The connections a.

zones II and III are connected to one another by the non-incised area 7 of the covering 1. There are two connections, ti and c, respectively, on each end face, from each of which an incision starts. / ». The connections are insulated from one another in the area of the incisions. On each end face there is a connection α or b at the connecting, non-incised edge areas 6 and 7, respectively. Dk connections c and ti are located on the free parts of the outer partial capacitances I and 111. If the two connections c and ti shorted, then yield; the. -7-oil shown in FIG.

The arrangement of FIG. 9 corresponds to that in FIG. 7. Only the connections c and d are earthed; The circuit diagram shown in FIG. 10 results in an asymmetrical desoling arrangement. The partial capacitances I and III form the Be-Hihrmigsschutzkondensatoren. which must have a high dielectric strength. These capacitors can therefore according to FIG. 1

The arrangement shown in Fig. 11 corresponds!

also that shown in FIG. The connection is rt grounded and the connections c and d are short-circuited. This results in the in Fi ^. 12 illustrated desoldering arrangement. The partial capacitances 1 and II form the touch protection capacitors. With these capacitors, too, the FIG. I or 2 a series connection can be used.

According to FIG. 13, the capacitive capacitors are rich in the partial capacitors transversely to the incisions 3 and 4, insulating strips 9 are introduced into the linings 1 and 2 , these and the linings being offset from one another, as shown in FIG. 15, giving way to a section two layers of a network? 13 is illustrated. If the output capacitor is made of metallized KunstsiorTolicr, then the insulating strips are all

free of traffic. In the figure Mnd only the sici «caraus er Issuing facing parts IO in facing I of the output

output capacitor shown. The lining parts 10 of the Coverings 1 and 2 are on top of each other so that a covering part is two directly below or above it partially covered. This results in an internal series connection for the partial capacities I, II. III, as shown in FIG. The inner series connection can of course also be connected with parallel connections of the partial capacities of the just described or other networks used pastures.

In a preferred exemplary embodiment of the invention, the following individual steps will be used: Metallized plastic films are placed on a drum or disk with a large diameter offset to one another to form one or more superimposed mother coils or output capacitors wound up. It becomes the whole

Mother winding provided with end contact layers. This will preferably be done so that the output capacitor is Additional mechanical protection when dividing or making the incisions will. The output capacitor or Mutterwickel is then necessary for a network Segments divided. It is also only now that the stimulus contact layers can be broken open onto the segments will. The corresponding
