Description

Known power supply arrangements of this type have two connector pins which, depending on the level of the operating voltage, are connected directly to the partial windings of the coil or via a resistor winding. The partial windings themselves as well as ^1, the resistance winding are connected to each other, depending on the circuit type (parallel or series connection) via connecting bridges. The hub clock mechanism can only be switched over when the operating voltage is changed when the. Protective housing can be made by reconnecting the connecting bridges with a screwdriver: a fact that is often very disadvantageous during assembly. The production of such connection socket is made by the necessary Drehtaile, such as screws, etc., as well as by threading and by a number of required additional parts, such. B. loose jumpers, more expensive.

There are already plug-in power supply systems became known with three Steckars ti ftan. Two of these connector pins are connected to the coil beginning and the coil end, while the third The plug pin is connected to the beginning of the coil via a series resistor. It is thus possible by optionally attaching a coupling piece to two of these connector pins, while the third is covered by an insulating sleeve, the hub clock coil directly or via a series resistor, thus optionally to be connected to two different voltages. Although such connector pin power supply In contrast to the version described in Section 1, it is very easy to manufacture are, no longer have any turning or screwing parts and simply plugging the coupling piece on Another voltage can be connected, they have the following very big disadvantage: Only in the lower of the two possible voltage ranges, the entire energy supplied is used, while with When connected to the higher voltage, part of the energy supplied in the series resistor is converted into heat is converted, so practically lost.

Switching devices from parallel to series connection of two sub-coils are not only with the pin power supply arrangement described in paragraph 1 used, but are also well known from the broadcasting industry. at the connection of the power supply unit of a radio set (mains transformer) is made via a Contact plate. This contact plate usually carries a number with the tail windings of the Netztransformatoirs Conductively connected contact rivet. By optionally screwing on one or more contact bridges establishes the desired connection between the transformer and the AC power supply system for electrical slave clocks

The special arrangement of the contact rivets means that two tail windings (110 V Alternating current) of the primary coil of the mains transformer connected either in parallel or in series (220 V AC). A similar contact plate is also often used for all-current devices, in order to supply the radio with the desired voltages and depending on the level of the mains voltage to destroy part of the same in a series resistor.

Although such ¹ switching and connection devices known from the broadcasting industry could in principle also be used to connect slave clocks, this option has not yet been used. These facilities not only require a lot of space, but also require loose parts such as contact bridges and screws, parts that have to be briefly separated from the movement during switching and can be lost under unfavorable conditions for connection to the existing slave clock voltage.

The invention is useful in pin power supply assemblies for slave clocks the elimination of the disadvantages of the known arrangements, d. H. on the one hand elimination of rotating tails and screw connections, on the other hand, such a simple one that uses the full tension in both positions at the same time Switching option that when plugging the loose coupling piece connected to the connecting cord the two partial windings of the Coils lie parallel to each other when attaching the Coupling piece, however, on the connector pins provided for the higher voltage, the partial windings can be independently connected in series.

These advantages are achieved with an arrangement equipped with more than two Steoker pins for slave clocks that can be switched to two different telecommunication (low-voltage) voltages, with which ■ the connector pins on the slave clock are firmly arranged so that each by a different plug-in the connecting cord coupling can be automatically switched over to two of the connector pins is, according to the present invention, in that two pairs of pins, so a total of four Connector pins are provided, two of which are connected by one each also arranged on the slave clock, but elastic and portable connecting piece can be connected conductively, and that firstly this Connecting pieces are so shaped and so arranged at a certain distance from a pair of plugs and that on the other hand, the coupling is dimensioned and provided with short-circuit ironing in such a way that when plugging in, the coupling on the one pair of plugs, the elastic connectors in which the plugs a pair of connecting layers remain while plugging the coupling onto the other Pair of plugs separated this connection, but at the same time the two connectors are short-circuited among themselves be, and by such. Allocation of partial wiokkmgen of the slave clockwork to the plugs that in one position of the coupling the partial windings are parallel, in the other position the partial windings are connected in series.

The depiction of the hub clock mechanism itself was omitted, since such mechanisms are considered sufficient are assumed to be known.

With the pressed body 1, the punched parts 5 sand through the holes. 8 firmly riveted. The upper ends of the Stanzteilei 5 are correspondingly angled, slotted and designed as connector pins 2 and 3. You break through the pressed body 1 in the direction of view. The two connecting pieces designed as leaf springs 4 are with. the two lower connector pins 3 are metallically connected and are under spring tension at connector pins 2. The lower ends of the punching tail 5 serve as solder lugs to connect the Part windings 9.

The coupling piece used for power supply carries a metallic one on each of its two flat sides Crossbar 6. The two crossbars 6 are riveted to one another through holes 7. The pressed body of the coupling piece is slightly angled towards the front. The distance between the connecting pieces 4 to the connector pins 3 is so large that the crosspiece 6 does not touch the connecting pieces when the coupling piece is inserted over the two connector pins 3. The sub-coils are in this case, as out Fig. 3 can be seen, connected in parallel.

If, on the other hand, the coupling piece is pushed over the two upper connector pins 2, the transverse web 6 presses the resilient connecting pieces 4 downwards, whereby the conductive connection to the Stecki.-rst.i-ften 2 is opened and the connecting pieces 4 via the transverse web 6 in be short-circuited. The current curve for this type of circuit is shown in Fig. 4. In Fig. 3 and 4, the fully drawn out rectangles indicate the connector pins connected to the master clock HU via the coupling piece.

The current-carrying metal parts (punched parts 5, rivets 8) riveted into the pressed body 1 are at the rear stripped from moisture by a plate made of insulating material, not shown in the figures.

In order to avoid incorrect connections, the plug pins 2, 3 are advantageously connected with the associated voltage, in the exemplary embodiment thus designated with "12V" and "24 V" (10, 11 Fig. 2).
