Hermaphrodite connectors for the win! They take up less space than a standard SMD right-angle pin header, and are very low profile, 2.3mm to be exact. These are rated 3A per contact. Not to mention not needing to worry about male and female connectors!
Which part num are these? I’ve seen similar from TE but they were rated 6A and a bit too large for my liking.
Oh, just found them. TE Miniature Hermaphroditic range. 3mm pitch instead of 4mm, which is an improvement, but still quite big. There is also a 0.5mm pitch version, but that is aimed at a completely different market segment.
Only slightly related: for heavier-gauge power hookups, I tend to use barrel connectors, but for higher current or applications where I want a really solid connection that doesn’t slip out, I’m thinking about switching to “power pole” links.

Anyone have experience with them?
I’ve used power pole connectors around batteries/upses/etc. They seem okay? Sometimes they’re really stiff, and a little painful to try to hold.
FWIW a friend that does this professionally uses something crmpable in the molex microminiature line. IIRC 40amp/connector.
Thanks for the real-world commentary.
Mfgr specs rarely say things like “painful to hold.”
@Kean_Maizels , specifically this one, TE’s 1971567-2. My only concern is how secure they are without the addition of a backing support as the specs mentions. I’m hoping since there will be four “strips” configured as a square inside of a tube, that it’ll be fine as the horizontal one will help align the vertical one and the same in reverse. But I won’t know till I get the samples and try.
Hrm, small snag with those … while they work great for joining the pieces together … unless I use wider strips, they’re not going to fit. And using wider strips means it won’t fit inside the tube. Oh the humanity …
AWESOME! I need to go look up the power specs on those.
Ratings:
A. Voltage Rating: 300V AC/DC
B. Current Rating: 3 A maximum
C. Temperature Rating: -40C to 105C
By the way, the thing is tested to 1600 V AC at sea level. It held with no breakdown. For something that small, I just have one word: DAMN
