CW CWR-143-40-0042 Pcb connector Datasheet

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.

• Sturdy, yet flexible solder posts,
able to withstand bending
and straightening.

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

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.
