Improved two-pole electrical plug

The present invention relates to improved electrical Plugs and especially plugs »those with a two-pole loiter are connected, for example, for dining at least one (lightbulb is intended. "...

It is known that, for safety reasons, light bulbs are advantageously fed with a low voltage current, ie in the "large". Orunung of 2h volts generally 110 or 220 volts. 'Pi>. The use of such a transformer is a hindrance for the user and entails costs for him *

The invention aims to "eliminate these disadvantages and one To create plug that reduces the current output.

The electrical two-pole plug according to the invention is characterized mainly in that it has a capacitor ¹ which is connected in series between one of the plug pins and the corresponding line of the cable, and a resistor

stood in series between the second connector pin and the second line of the cable is connected,

According to a preferred embodiment, a shunt is used a resistor between the two pins of the connector that absorbs the discharge current of the capacitor, when you pull the plug out of the socket.

The invention is intended in the following on the basis of an exemplary embodiment will be explained in more detail with reference to the figures of the drawing. Show it:

1 shows a longitudinal sectional view of a connector according to the invention,

Fig. 2 shows the circuit diagram of the plug connected to a light bulb and

3 is a perspective view of an electrical installation with a connector according to the invention.

The plug F according to the invention essentially has a base plate 1 (FIG. 1) which ^{carries two plug pins 2, 2 f} , a protective jacket 3 and a cable 4 with two lines 5 and 6.

The base plate 1 is preferably made of a rigid plastic around the heads 2a and 2'a of the connector pins 2, 2 * in such a way is cast so that they are firmly connected to the base plate. The scope of the base plate is graduated. He shows a shoulder 1a and a recess 1b which carries a ring attachment 1c.

The jacket 3 is advantageously made of a semi-rigid plastic. It has the general shape of a hollow pear, and walls preferably have the same thickness as that of shoulder 1 a of base plate 1. The inside 3a of the large opening of the jacket 3 has a groove 3 *>. It can be seen that won

so the jacket on the circumference of the base plate 1 by engaging of the ring attachment 1c can clamp into the groove Jd, while the Neck 3c of this jacket is stretched around the cable 4 «

The head 2a of the plug pin 2 is connected by a rigid line 7 to one of the terminals of a capacitor 8, the other terminal of which is connected to the conductor 5 of the cable 4. A resistor 9 is connected in series between the head 2 'of the plug pin 2 ¹ and the second conductor 6 of the cable 4. Furthermore, between the connector pins 2 and 2 ″ on: Resistor 10 is connected in parallel.

The operation is as follows:

The cable 4 leads to a light bulb 11 (Fig. 2). The plug pins 2 and 2 'are inserted into the sockets 12, 12 ⁵ J which are connected to each of the phases 13, 1J ^{1 of} an electrical mains connection with, for example, 220 volts is, the resistance of its filament is sufficiently large that the supplied continuous current can be low.

The capacitor 8 plays the role of an intensity limiter and acts like a resistor in the circuit, but without heating. The capacitor generates a current of lower wattage, and the resistor 9 has the purpose of a phase shift to counteract.

A diminished value is thus obtained at the terminals of the light bulb 11 Current that corresponds to the feed current permissible for the light bulb.

In Fig »3 is a placed on a console 15 vase 14, the an artificial flower 16 is shown in which a 'light bulb;

11 is arranged, which is connected to the power supply by means of the cable 4 and the connector F according to the invention. Because of This plug ensures that the amount of current that can pass through the lightbulb is so limited that a long service life of the same is certain. '

With an electrical network of 220 volts, one can use a 24 volt light bulb, the allowable amount of current of which is 0.04 mA, using a capacitor of 0.47 / uF and a resistor of 220 XX .

The resistor 10, which is designed to absorb the discharge of the capacitor when the connector F is pulled out, is measured at 150,000 Sl.This resistor 10 plays the same role when it is connected in parallel to the terminals of the capacitor 8 .
