I have an application where I have multiple PCBs connected to each other where each board edge is 45 degrees to the mating board. There are plenty of right angle connectors and straight connectors, but has anyone ever used 45 degree connectors? I have very low constraints in the connector, a simple 0.1" pitch 3 pole header is sufficient.

I am essentially looking for a product in between these two P/Ns (as an example): M20-9960345, M20-9990345

Another note is that I am aware that I could manually bend a straight connector to 45 degrees to accomplish this, but this would be for production so I would like an off-the-shelf solution.

Thanks!

    \$\begingroup\$ It could be interesting to just contact some manufacturers about this. Who knows, custom connector prices might be lower than you expect. \$\endgroup\$

  • \$\begingroup\$ Hey, good point. I'll probably try this, the problem is I will be prototyping in smaller quantities so I suspect it may not be cost effective to start. But who knows, I may be surprised. \$\endgroup\$

  • \$\begingroup\$ I remember there are 15 degree degree dimm connectors, used by a Gigabyte RAM hard drive (to fit 4 dimm memories into a single PCI slot). 45 degree should also be available. \$\endgroup\$

  • \$\begingroup\$ Sounds like a nightmare design. Are you sure it has to work this way? \$\endgroup\$

  • \$\begingroup\$ It needs reinforcement when at an angle otherwise use a smaller header 0.5mm \$\endgroup\$

  • \$\begingroup\$ Phoenix do an equivalent, and do solder mating connectors (e.g. this. Thus it can be used as board-to-board \$\endgroup\$

This is a standard option from header makers such as Samtec. Here is a screen cap from their site where they explicitly offer what you are asking for:

I think you can see from the top photo that your requirement should not be very challenging to them.

One semi-jankey solution would be to use oversize through holes or plated slots, so that your headers can be inserted at an angle. If soldered with a jig, it could even be fairly reliable.

Another option would be to use castellated holes on the board edges and solder them together directly.

As stated in the comments, certain manufacturers specialize in custom solutions. If you are willing to meet MOQ numbers the prices should reasonable for such a trivial modification, and they might not charge you for the tooling.

A flex circuit jumper could be used. These are like a small printed circuit but with kapton or mylar substrate. A quick look at one online distributor indicates stock lengths are available, but again, you would probably require a custom to obtain the length you need. There are board mounted connectors that the flex jumpers mate with.
