VU connector is small type 3.96mm pitch
PC board connector for large current and
has the high reliability in a power supply
circuit, considering the fully shrouded
connector header structure against
"vibrating connector" and "distorted
extraction".
Features ––––––––––––––––––––––––
• Secure locking device
The housing has a locking device to securely hold the header,
preventing accidental disconnection, because of external force
that might result from the routing of wires or of vibration, inverse
insertion and mating with incorrect circuit.
• Shrouded header
Shrouded header provides the longer creepage distance and
countermeasure for distorted extraction of connector.
• Flanged press pin
Header pin is the flanged press pin, preventing accidental
removal of the pins due to distorted extraction of connector.
