Description
Из распространенных видов освещени переговорных будок следует отметить налольныЁ настил с замыкающимис при нахождении абонента в будке контактами и специальный дверной выключатель, дающий зажигание лампочки во врем открыти и закрыти двери.Of the common types of lighting of telephone booths, it should be noted that the flooring is closed with contacts closed when the subscriber is in the booth and a special door switch that switches on the light bulb when the door is opened and closed.
Предлагаемое изобретение касаетс устройства дл освещени переговорных телефонных будок и состоит в том, что электрические лампочки включаютс одновременно со вставлением штепсел в соответствующее гнездо коммутатора и выключаютс вытаскиванием штепсел из гнезда последнего.The present invention relates to a device for lighting telephone booths and consists in the fact that light bulbs turn on simultaneously with inserting the plug into the corresponding slot of the switch and turn off by pulling the plug from the plug of the latter.
Согласно схеме, гнездо коммутатора имеет семь пружин (пружины 3 и 6 дл включени разговорных жид, пружины 4 и 5 дл включени вызывного номера), смонтированных в общую монтажную схему коммутатора и изолированную пружину 7, оканчивающуюс штифтом в местном ноле. Добавочна нружина 8 установлена в гнезде станционного коммутатора и соединена с «плюсом станционной батареи. Электрическа лампа 9 включена в осветительнуюAccording to the diagram, the switch socket has seven springs (springs 3 and 6 for switching on conversational fluids, springs 4 and 5 for switching on the call number) mounted in the general wiring diagram of the switch and an insulated spring 7 terminating in a pin in the local field. A supplementary spring 8 is installed in the socket of the station switch and connected to the “plus station battery. Electric lamp 9 is included in the lighting
сеть через корь реле Р, один конец обмотки которого соединен с «минусом батареи , а другой-с нружиной 7.the network through the measles of the relay P, one end of the winding of which is connected to the “minus of the battery, and the other to the spring 7.
При вставлении штепсел , в гнездо, по обмотке реле вройдет электрический ток, реле сработает, замыка электрическую цепь лампочки 9. По окончании переговоров , телефонистка вынимает штепсель, размыка тем самым пружины 7 и 8, вследствие чего реле Р лишаетс тока и выключит лампочку 9.When the plug is inserted into the socket, an electric current is inserted at the relay coil, the relay will work, short circuit the electric circuit of the light bulb 9. At the end of the negotiations, the telephone operator removes the plug, thereby opening the springs 7 and 8, as a result of which the relay P loses current and turns off the light bulb 9.
Предмет патента.The subject of the patent.
