2. Simplified Assembly for Sizeand Weight Reduction
FPC

Insert the FPC into the plug housing and securewith the retainer to complete the assembly,
streamlining the harnessing process andenhancing work efficiency.
The plug side consists of only the FPC, plughousing and retainer in a terminal- less design,
which contributes to weight reduction byswitching from discrete wire to FPC and spacesaving in FPC routing.
