I suppose you all know jumpers, those little things you put on top of 2 male, 2.54 mm pitch, pins. They serve to connect the 2 pins together (often used to "configure" a prototyping board), for example selecting a voltage or I2C address:
My question is: what's the opposite called? By opposite, I mean a component having roughly the same shape, that I can put on top of 2 male pins with 2.54mm distance, but that does NOT connect them?
For background: why do I want that?
I'm currently designing a PCB for a caving robot. I have several rows of pins to connect various sensors/actuators, where I would like to use 2.54 mm pitch pins.
In order to avoid risking shorts with all those pins, I would usually just use female pins. The problem is that in caves, there is mud, and if I get some mud in a female pin, it will be nearly impossible to get out again.
So my goal is to protect the pins from accidental shorts.
