This wire guide under the PCB serves to guide the wires and avoid any potential short-circuits that could be caused with the pins that go through the PCB.Here are a few images
What wires are going underneath?
The wires that go to the battery modules are:
Thermistors
There are 4 thermistors on the module,
How much room do we need for the wires?
Requirements of the design:
Protect the wires from shorts to the underside of the PCB module (the pins for the connectors poke through the board)
Provide strain relief - I need to make a confluence page on why this is important
Images of the design:
Where is it located - on top of the module acetal isolation cover, below the PCB
...
What wires need to go through here and where do they go?
...
The area with all 14 wires going through it at the top will be filled with a rubbery glue - to provide some strain relief to the cables.
