PCB Connectors The PCB connector is used when a permanent connection of flat cable to the PC board is required. The cable is terminated to the PCB connector making a reliable gas-tight connection with CW’s patented Torq-Tite™ contacts. The connector’s pins are then soldered to the board. CW’s PCB connectors are approved by the U.S. Defense Department and are qualified to Mil-DTL-83503/23. • Built-in strain relief is available to protect contacts if cable is pulled. • Available with or without protective cover lip for cable end or daisy chain applications. • Patented Torq-Tite™ contact keeps conductor under constant tension. Assures a mechanically and electrically sound, gas-tight connection. • No “bare shoulders”. No exposure of unnecessary sections of the contact and possible shorting at the PC board interface. 34 • Sturdy, yet flexible solder posts, able to withstand bending and straightening. • 130 James Way, Southampton, PA 18966 - 3838 • Telephone: (215) 355-7080 • Fax: (215) 355-1088 • www.cwind.com PCB Con n ector Featur es • Sharp points allow contact to pierce tough insulation materials • 10, 20, 26, 34, 40, 50, 60, pin versions • Tin-lead plating, standard; gold plating also available • Available with or without strain relief lip • Contact tines are firmly connected to the body of the contact • Available with or without cover lip for cable end or daisy chain application • No “bare shoulders” on the contact at the PC board interface. • Accepts 28-30 AWG stranded or solid conductors • Rugged, lightweight UL 94V-0 thermoplastic construction • Spring temper, phosphor bronze material resists breakage during bending or straightening operations • One tail length can be used with 1/8 in. or 1/16 in. PC boards • Rounded tip provides lead-in to mate with PC board holes PCB Connectors Con tact Str ain Relief A molded-in strain relief is an optional feature on CW PCB connectors. (Specify CWR-140 or CWR-143 series). This lip, upon installation of the cover, creates a strain relief bend in the cable, inhibiting the transfer of any tension on the cable to the contact lines. Cover Lip For additional protection on cable end terminations, the CW PCB connector is available with a cover lip to insulate the ends of the cable’s conductors. This eliminates possible “shorts” and allows you to position connectors more closely on your PC board. (Specify CWR-140 or CWR-141 series). Assembly To terminate CW PCB connectors to flat cable, use CT301 86/81 assembly press. The cable is applied directly to the IDC contacts in the connector base and then the cover is assembled. • 130 James Way, Southampton, PA 18966 - 3838 • Telephone: (215) 355-7080 • Fax: (215) 355-1088 • www.cwind.com 35 PCB Connectors En gin eer in g Dimen sion s Dimen sion s C D .425±.010 (10.80±.25) .40 (10.2) CL ±.010 (±.25) .050 Cable Slot for Center Cond.
