Hello, today I admired some artifacts of the Soviet era and wanted to share with the public. The post will not contain technical analysis or historical background, just pictures for the curious and my notes. Therefore, I publish in the "closet". (Beware of pictures 40 Mb!)
electrical connector
According to legend, he is from the brother of "Buran" - "Storm". Note that the wire is embedded in a brown compound, the plastic cover and the fill hole 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 enter the grooves of the ring are pressed in and flared from the inside, made of another metal. The metal contacts come out of the soft sealing gasket.
It looks very technological and cool, snaps clearly, especially after cleaning. But the ring is not very grippy, it is necessary 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 latch in the pressed position. The green ring is a light accumulator.
milliammeter
Rated up to 100 mA '73. The front panel is made of ebonite.
The case is molded from light plastic, surrounded by a metal screen
Voltmeter
Similar to the previous one, but matting on the glass was added.
The case is of a slightly different design, a viewing window is visible from the back, glass is planted on a sealant (possibly plexiglass). I wonder what it's for?
Voltmeter 30V
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. Behind the bottom is an incomprehensible plastic plug.
Scribbled between the terminals:
If you liked the format and the exhibits, then I will be happy to shoot more.
