The plug kit consists of a plug assembly and USB (which consists of a plug contact and stamped and formed
backshell). The plug contact of the USB Series A has one set of four adjacent insert molded contacts, and the
USB Series B has two sets of two opposing insert molded contacts. The solder pads are numbered for proper
wire arrangement. The backshell provides shielding and grounding continuity for electro--magnetic interference
(EMI) and electro--magnetic compatibility (EMC). The USB components are designed to be terminated to the
wires by soldering and terminated to the cable by crimping. The cable fitting (plastic shell) or dome nut (metal
shell) of the plug assembly holds the USB in the plug assembly and seals the USB at the cable end.
The receptacle kit consists of a receptacle assembly (which contains a USB coupler), panel nut, and panel
gasket. The receptacle assembly features a flange that allows front-- or rear--panel mounting and a flat for
indexing the receptacle to the panel. The panel nut is used to mount the receptacle to the panel. The panel
gasket seals the receptacle at the panel.
A protective cover assembly is available for each connector to prevent contamination when the connectors are
not engaged. The protective cover assembly includes a tether that can be used to attach the cover to the
connector.
The mating face of the connectors are polarized for proper orientation when mating. When mated, the
connectors are held together by a locking mechanism (coupling ring and bayonet lock) which prevents
accidental disconnection. The mated connectors are sealed by the interfacial seal of the plug assembly.
