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. 2 of 13 Tyco Electronics Corporation Rev E Industrial Circular Standard USB Panel- Mount Connector System 114- 13211 2.

Cable Selection and Preparation A. Selection The plug contacts accept 4--conductor solid or stranded individual wire sizes 20--28 (power--signal), 22--28, 24--28, 26--28, or 28--28 AWG with a cable outside insulation diameter range of 4.0 mm [.157 in.] through 6.5 mm [.256 in.] for plastic shell and 4.0 mm [.157 in.] through 5.4 mm [.212 in.] for metal shell. Allowable length of the cable assembly according to wire size is given in Figure 2. B. Preparation The plug assembly must be installed (strain relief end first) onto the end of the cable before preparing the cable. Proper strip length is necessary to properly insert the wire into the contact. The strip length of the cable is shown in Figure 2. CAUTION ! Reasonable care must be taken not to nick, scrape, or cut any part of the cable during the stripping operation. Care must also be used when handling the cable during stripping to prevent cracking or breaking of the braided shield, wires, or insulation. After the braided shield is stripped, it must be rolled back over the jacket and wrapped with copper tape. After the individual wires are stripped, each wire must be pre--tinned with solder.

Plug Contact and Plug Backshell (See Figure 7) USB Series A The cover of the plug contact must be "snapped" onto the solder pad housing. The latches of the cover must be secured to the tabs of the solder pad housing. There should be no gap between the cover and the housing. When inserting the plug contact into the front shell, the bottom of the housing must be aligned with the seam of the front shell. The cable jacket must be positioned in the strain relief of the front shell. The rear shell must be manually "snapped" onto the front shell so that the latches on the sides of the rear shell engage the windows on the sides of the front shell. There should be no gap between the front shell and the rear shell. When fully assembled, the housing of the plug contact must be bottomed and flush with the mating face of the backshell. USB Series B The cover halves of the plug contact must be manually "snapped" together over the solder pad housing. There should be no gap between the covers and the housing. When inserting the plug contact into the plug backshell, the "D" profile of the front of the housing must align with the "D" profile of the mating face of the front shell. The cable jacket must be positioned in the strain relief of the rear shell. The front shell and rear shell of the plug backshell must be manually "snapped" together so that the locking latch of the rear shell engages the locking detent of the front shell. The latches on the sides of the rear shell must engage with the windows of the front shell. When fully assembled, the housing of the plug contact must be bottomed and flush with the mating face of the plug backshell.

Installing USB into Plug Assembly It is recommended that the USB be installed into the plug assembly so that the seam aligns with the TE logo embossed on the front of the plug housing (located over the USB port). The assembled plug assembly must meet the following requirements: -- the USB protrudes from the housing of the plug assembly to the dimension given in Figure 9 -- the strain relief is tight to a torque between the range provided in Figure 9 NOTE i The torque must be within the range provided in order for the strain relief to seal the plug assembly at the cable end as defined in IEC 60529, IP Code 67. 3.7. Panel A. Indexing Indexing the receptacle to the panel can be chosen when cutting the panel. There are 4 rotational orientations for mounting the receptacle assembly to the panel: left, right, top, and bottom. The flat of the receptacle assembly fits into the flat edge of the panel. The flat edge also prevents the receptacle from rotating when securing it to the panel. 8 of 13 Tyco Electronics Corporation Rev E Industrial Circular Standard USB Panel- Mount Connector System 114- 13211 Installing USB into Plug Assembly Note: Not to Scale Plastic Shell Series A (Same Applies to Metal Shell) TE Logo Embossment Metal Shell Series B (Same Applies to Plastic Shell) TE Logo Embossment 1 Seam Seam USB Port USB Port 2 Strain Relief is Tight (See Table) Strain Relief is Tight (See Table) 11.8-- 13.8 mm [.465-- .543 in.] (From USB to Plug Housing) 11.8-- 13.8 mm [.465-- .543 in.] (From USB to Plug Housing) TORQUE RANGE PLASTIC SHELL METAL SHELL 1.7--2.8 N--m [15--25 lbf--in.] 0.9--1.4 N--m [8--12 lbf--in.] Figure 9 B.

Disassembly The connectors can be un--mated by rotating the coupling ring of the plug which releases it from the bayonet lock of the receptacle (there should be an audible "click"), then pulled straight away from the receptacle. The receptacle can be removed from the panel by removing the panel nut. 3.14. Replacement and Repair All components of the connector system are not repairable. Defective or damaged components must be replaced and MUST NOT be used. The panel gasket can be re--used if not worn. Plug contacts MUST NOT be re--used by removing the wire. A plug contact MUST NOT be removed from the backshell and re--used. 4.
