My thoughts would be connectors that have some form of "locking". 3.5MM,
RCA, coaxial power, for instance, all cannot be locked to prevent
disconnection. I normally use plastic MOLEX connectors, with a row of pins
missing. When extra security/ locking is needed, a ty-wrap around the whole
thing keeps it together. (Ty-wrap goes where the pins are missing., for
instance on a 9 pin 3 rows x 3 rows, middle row is empty)
