Narrow-pitch connectors P4
Reinforcing plate 0.3mm PCB 1.8mm
The simple lock mechanism ensures that the connector clicks into position when it is inserted for reliable single-action insertion on the PCB.
A stacking height of 1.8mm including the FPC area has been achieved. This enables the number of pins to be doubled white the size remains the same as that for existing FPC connectors. This, in turn, contributes to making products and equipment more compact.
FEATURES
1. A 0.4 mm pitch and stacking height of 1.5 mm allow for extra compactness and helps design lighter, thinner, shorter, and smaller devices.
2. High impact-resistant construction. 1) Adoption of bellows-type contacts structure.
The roll surfaces are in contact with each other, providing high contact reliability.
Since the contact is formed by bending thin plate, it has a springlike quality. This construction helps make it resistant to dropping and twisting.
2) It is constructed with impact dispersion keys inside the body to disperse shocks when dropped.

A high level of shock resistance is ensured by dispersing impact over the four locations where the socket indenta-
tions anDdahtaeSadheerept4roUtr.ucsoiomns are mated
together. 3. Construction makes designing devices easier. 1) The lower connector surface construction prevents contact and shorts between the PCB and metal terminals. This enables freedom in pattern wiring, helping to make PCB’s smaller.
2) Guides are provided to take up any position shift and facilitate insertion.

3) The connector has a simple lock mechanism.

4. Design makes efficient mounting. Features a terminal flatness of 0.08 mm, construction resistant to creeping flux, and design that facilitates visual inspection of the soldered part.
APPLICATIONS
• Cellular phones • DVC • Compact portable devices
