One of the most successful connectivity technologies is Universal Serial Bus or USB 2.0.
(Click here for a tutorial on USB technology.)
You can find it everywhere, from laptops and desktop computers, to peripheral devices like printers, mice and keyboards, to consumer electronics like cell phones and camcorders. That’s why it’s surprising to note that there are some fundamental problems with USB 2.0, one of which is its sensitivity to vibration.
USB 2.0 uses what’s called “friction fit” to remain connected, which means the friction between the connector and the jack is all that holds the connection together. Vibration, as you’d find in vehicles and military/aerospace applications, can cause connectors to unexpectedly separate.
L-com has countered this problem by offering “latching” USB 2.0 cables. The latches, which are on the sides of the connector, fit into any standard USB 2.0 female jacks. Currently latches are only available on USB 2.0 Type A male connectors and they come standard on micro-B male connectors. L-com offers:
