2 Pin Magnetic Pogo pin connector mount

This is to mount a beefy 2-conductor pogo pin connector to wooden surfaces.

It is designed for this part:

Important:

• There are 2 sizes (diameter) of that part available: 8mm and 10mm

• I originally designed this for the 10mm part.  I more recently added STLs for the 8mm part.

• The 3MF includes both files, and I include STEP files as well.

• The Fusion 360 file is also available for easy adjustment/remixing.  The diameter (8mm or 10mm) is a parameter in the model (MODIFY > Change Parameters > pogoDiameter).  The file I uploaded has been set to 10mm.

I chose this part for a few reasons:

• beefy:

  • the pogo pin is 20 gauge (5+ amp capacity)

  • the magnets are very strong

  • they contain a washer that both protects the magnets from cracking and making a second contact.

• 2-pins: as long as the two sides make complete contact, you can use one pair for 2 conductors.

• good price.  Some other products are 5 times more.

• available on Amazon.

Unfortunately there is no reasonable way to mount these other than to a PCB .. except if you own a 3d printer.  The mount features:

• the holder for the male side has a print-in-place sliding action with 4mm of travel (2mm in and 2mm out).  I will place these in a piece of furniture such that gravity pulls the part down.  This retracts it and prevent damage to the pogo pin.

• the holder for the female side is fixed.

• when brought together, the strong magnet pops the male side out to make contact.  They are both slightly raised from the surface of their mounts so the washers make full contact.

• both sides utilize grip fins to hold the parts firmly without the need for glue.  You just press fit the parts into the mounts and they hold.  They can easily be removed by pushing them out from the other side with needle nose pliers, screw driver, etc.

• designed for a 7/8" hole (use a forstner bit)

• designed for a 1/2" router bit ... there is an optional template to route the mortise to embed the mounts flush in wood.

Printing:

• no supports needed.

• recommend settings: 3 layers, wall generator: Arachne.

• there is a 1 layer bridge built into the model that needs to be removed with needle nose pliers.

Why did I design this?

I'm building some furniture with LED lighting that needs to be removable for cleaning and maintenance.  I'm designing an LED light module (think a minimal wood frame around an LED strip) that slides out and I want a hands-free way to electrically connect it for power.  This solution ticks all the boxes - the electrical connectors can be recessed into the furniture pieces and they pop out and have some play with a bit of tolerance for misalignment .. while being able to carry enough current to drive the LEDs.
