The standard USB connector uses a push pull interface with no latching. It relies on the design of the mating interface and the ground tabs to maintain the connection of the plug to the receptacle. Currently there are applications in a number of markets where vibration and inadvertent separation of the cable is a potential problem due to loss of data when the mated interface is accidentally broken.
The design of Amphenol Canada’s USB, Series A with this unique latching mechanism has been developed to address this major concern of unintentional interruption of data transmission. The latch must be intentionally raised in order to remove the plug. An accidental pull on the cable up to 22 lbs (10 kg) force will not separate the connectors.
