CONNECTOR
• Compact
2.0mm
(.079") pitch
Disconnectable Insulation displacement connectors
Features–––––––––––––––––––––––
This connector measures 2.0mm (.079") in pitch, 5.0mm
(.197") in mounting height, and 4.8mm (.189") in thickness.
• Twin U-slot insulation displacement section
The insulation displacement section connected to each wire
consists of two tin-plated slots (twin U-slots), which ensures
reliable connection.
• Folded beam double-leaf contact construction
As contact become smaller, their spring strength is reduced.
To solve this problem, a folded beam construction is
employed to increase contact spring strength.
• Strain relief
A strain relief secures the wire insulation to protect the
insulation displacement connection against vibration, impact
and other external forces. A triangular projection on the
shrouded header functions to prevent connector distortion
during connection and disconnection, to reinforce the strain
relief and to prevent the conductor of the insulation
displacement section from being exposed.
Measuring 2.0mm (.079") in pitch, only
5.0mm (.197") in mounting height, and
4.8mm (.189") in thickness, the DR
connector is a compact insulation
displacement connector developed to
meet the needs for miniaturization of
electronic equipment, including VCRs,
cameras and car stereo systems.
