Tere, täna imetlesin mõned Nõukogude aja artefaktid ja tahtsin neid ühiskonnaga jagada. Postitus ei sisalda tehnilist analüüsi ega ajaloolisi märkusi, ainult pilte uudishimulikele ja minu märkmeid. Seetõttu avaldan selle "pööningul". (Olge ettevaatlik, pilte 40 Mb!)
Elektriline pistik
Legendi kohaselt on see pärit vend «Buran» — «Buri». Pange tähele, et juhe on valatud pruuni komposiidiga, nähtav plastikust kate ja valamisava.
Üllatab kirja täpsus ja täpsus. Huvitav, kuidas see on kantud, šablooniga? Templi abil?
Pistik liitub rõnga pööramisega kolme sälguga.
Torkeid, mis sisenevad rõnga sälgudesse, on pressitud ja seestpoolt laiali vajutatud, valmistatud teisest metallist. Metallkontaktid tulevad pehmest tihendipakist välja.
Tundub väga tehnoloogiline ja lahe, istub kindlalt, eriti pärast puhastamist. Kuid rõngas ei ole väga kinnituv, tuleb töötada kinnastega, siis ühendub see suurepäraselt.
Nupp
Legend has it that this is the "helicopter button." I must note that all these things came to me long ago in childhood, and I can't guarantee the accuracy of the description. The button is not a switch, i.e., it doesn’t latch in the pressed position. The green ring is a light accumulator.
Milliamperemeter
Marked up to 100 mA 73 year. The front panel is made of ebonite.
The case is made of light plastic, surrounded by a metal shield.
Voltmeter
Similar to the previous one, but the glass is now frosted.
The case has a slightly different design, with a viewing window visible from the back, fitted with sealed glass (possibly acrylic glass). I wonder what it is for?
Voltmeter 30 V
Like the previous two devices, it has a slot for adjusting the balance with a flat screwdriver. However, this device also has a second needle, which is rigidly connected to the upper 'screw'. Apparently, it indicates the optimal voltage in the system.
Notably, the case is cast! Only the flat cover at the back opens. At the bottom rear, there is an unclear plastic plug.
Between the terminals, it is scratched:
If you liked the format and exhibits, I would be happy to shoot more.
