There are also some pretty large busbars. The connection here is done with 14 bolts the size of a man's thumb.

As mentioned in the comments, those swaged turret pins. They are used to connect heavy guage wire to PCBs. The pin itself is "swaged" onto the PCB - it is rather like a rivet. The swaging provides mechanical strength. The pin can also be soldered to the PCB to ensure a good electrical connection. You can solder wires to the pins to connect things ...

Why are you immersing your assembly in oil? The only reason I can think of is that you intend to submerge it. So, I'll work on that assumption. First, any component that has an airspace is a problem. All those airspaces need to be filled with the fluid to balance pressure. Knowing this, and knowing how most electrolytics are made (they're layer stacks rolled ...

They're called several different things: Magnetic Compression Contact Spring-loaded Magnetic Connector Magnetic Pogo Pin Connector Some examples I found are Adam Tech, CLE, or Hytepro.

A message for those not understanding the first part of this answer A connector, on the face of it, connects electricity to a load but, in the detail of that connection, are EM waves. In simple terms we call it electricity but in reality there is an electromagnetic wave; that is what is being passed from A to B. At the instant the "connection" is ...

The schematic is a bit confusing, or this is a multi-purpose connector. It is being called a stereo jack, yet pin call-outs are (1)=GND, (3)= TIP, (2)=RING, as if it was a telephone switch-board jack from many decades ago. In the days of mechanical switchboards this connect/disconnect feature allowed a used jack to light a small lamp. Each jack had its own ...

Seems to be a Panasonic P5KS Series connector, likely the AXK5S24047YG, or a similar one from the series. A mating connector for this one would be an AXK6S24447YG or similar. See the datasheet and the obligatory Digikey link. Obligatory Digikey link I found this by searching Digikey, going to the Connectors, Interconnects category, then Rectangular ...

Yes that is normal, the sleeve connection of the jack most likely touches the tip and ring when plugging and unplugging. Yes, wiring large battery currents via a short-prone audio connector rated for 1A max current does seem like a bad idea. It is a completely wrong tool for the job. There are far more suitable connectors available that are designed for ...

The connector looks to be an SMT type similar (but maybe not identical) to this JST PH series part: The two brown squares are where the pads were that provided mechanical support for the connector. They are now gone (still attached to the connector since the glue that holds the copper on was weaker than the solder). The two pins you can see in my photo are ...

Your connector is still there. It's attached to the cable, but ripped off the PCB. That's why you've got copper red-brownisch rectangles at the bottom of your plastic piece, and missing on your PCB. Since it's ripped off, there's noting to solder it on to, so: Is it possible to solder directly to the motherboard? Not in general. You will have to figure out ...

Dielectric constant of oil will be much higher than air, 2-3x more probably. If your circuit has high frequency tuned circuits or fast edges the additional capacitance and cross-talk might have some negative effects. That may affect some circuits. I would be particularly worried about the electrolytic capacitor seals. In fact Chemi-Con says: As @Hearth ...

The EL wire system runs up to 120V, per IPC specs an 0.2mm or 8mil clearance should be used between traces and connector pads on the PCB with 120V (150V). In addition, 16mil should be used between coated insulation on wires. This means any connector could be used that has an 8mil clearance between the connectors. I like molex and JST connectors, if I am ...

They've provided a very poor drawing. 3 and 4 obviously disconnect when the jack is inserted. I suspect that 5 and 6 do as well but that contact is isolated from 2. That way it can be configured to work the same way as the tip contact by permanently connecting 2 to 5. When the jack is inserted 2 will be disconnected from 6. Alternatively you could leave 5 ...

Those terminals look like they are intended for soldering. There won't be any other type of connector. So wire, solder and soldering iron required.

Most of the connector I have found are only 2.5Amp, but for safety it should be derated a bit depending how much overall power is going through it.

Here is your answer, sir, as regards the d531. I really hope this helps you.
