looking for a way (connector) to interconnect identical pcb's
(1/3) > >>
kripton2035:
Hi folks,
for an upcoming project, I would like to interconnect pcb's that are similar.
something you can add identical pcb's each time you need it
so I need to have one female and one male connector, that are horizontal and at the edge of the pcb
they must support mains voltage (as well as small voltages also)
I would like not to use wires between the pcb's.


what are my options for this ?
thanks.

An idea of the size would help.
max_torque:
Important factors to be considered (in no particular order right outta my head)

1) Number of mate/de-mate ops (some connectors not designed to be connected and disconnected often can have surprisingly few cycles before their resistance increases
2) Voltage levels - do you need to protect the operator for any "High" voltages (anything over 50Vdc is typically considered "high" from an H&S perspective)
3) Environmental/sealing - do you need any? bare pins, waterproof, vibration resistance etc etc
4) Keying - will all connectors be able to fit into all sockets? or will some need keying to ensure they only get inserted where they should
5) Mechanical strength and support - relevant to 1) also. How strong and does the connect need to interface (be supported by, or sealed too) the enclosure in which the electronics may sit
6) Current carrying requirement
7) ESD protection (touch proof pins etc)
8) Volume - how many do you need and how are they being assembled
9) Cost
10) Signal bandwidth and shielding requirements


As you can see, just asking "what connector" is not really enough.

Solutions range between 1 cent bare pin headers and $1000 space rated interconnect systems depending on the answers to those ^^ questions   :scared:

between 3 and 10 pins. 2.54mm spacing or eventually 1.27mm
I think 2.54mm for mains pins spacing is the minimum ?
kripton2035:
it is to transmit mains and some signals (i2c, spi, or low frequency signals) from one pcb to another (same pcb to another if needed)
no vibration, waterproof not needed, low volume hobby use.
they won't be connected/disconnected often, only during first tests after that they will stay forever connected.
