Soviet technical aesthetics and technology
Hi, today I admired some artifacts of the Soviet era and wanted to share with society. The post will not contain technical analysis or historical background, just pictures for the curious and my notes. Therefore, I publish in the "closet". (Caution: 40 Mb pictures!)
Electrical connector
According to legend, he is from the brother of “Buran” - “Storm”. Please note that the wire is poured into the brown compound, the plastic cover and the hole for filling are visible.
Surprising accuracy and accuracy of the inscription. I wonder how it was applied, a stencil? Stamp?
The connector is connected by turning the ring with three grooves:
The pins that go into the grooves of the ring are pressed and flared from the inside, made of another metal. Metal contacts come out of the soft gasket:
It looks very technological and cool, snaps clearly, especially after cleaning. But the ring is not very oversized, you need to work with gloves, then it connects perfectly.
Button
According to legend, this is a "button from a helicopter." It should be noted that all these things came to me a long time ago in childhood and I can not vouch for the accuracy of the description. The button is not a switch, i.e. does not snap in the pressed position. Green ring - light accumulator:
Milliammeter
Marked up to 100 mA 73 year. The front panel is made of hard rubber:
The case is molded from light plastic, surrounded by a metal screen:
Voltmeter
Similar to the previous one, but frosting on glass was added.
The case is of a slightly different design, the viewing window is visible on the back, glass is seated on the sealant (possibly plexiglass). I wonder what it is for?
Voltmeter 30 V
Like the previous two devices, it has a slot for adjusting the balance for a flat screwdriver. But this device still has a second arrow, which is rigidly connected to the upper "bolt". Apparently, to indicate the optimal voltage in the system:
It is noteworthy that the body is cast! Only the rear flat cover opens. In the back, from below, an incomprehensible plastic plug:
Between the terminals is scratched:
If you liked the format and exhibits, then I’m happy to shoot more.
