Latching USB Cables

One of the most successful connectivity technologies is Universal Serial Bus or USB 2.0. Why? 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.

Surprisingly though, there are some fundamental problems with USB 2.0, one of which is its sensitivity to vibration.

USB 2.0 uses what's called a "friction fit" to remain connected, which means the friction between the connector and the jack is all that holds the connection together. As you'd find with vehicles and in military/aerospace applications, vibration 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:

 

 
 
Quick note: Latching connectors are also available for SATA cables.
 
Additionally, L-com now offers USB 3.0 cables with locking thumbscrews. These cables can be used in machine vision applications or with any application where vibration is an issue.
