Board-to-FPC Connector for Automotive Less Wiring Harness, More Storage Space

Mit dem CF1-Steckverbinder verspricht Panasonic mehr Platz in Automotive-Anwendungen.

A new connector from Panasonic connects flexible circuit boards in cars directly to the circuit board. The effect: Fewer components, more space.

Conventionally, flexible printed circuit boards (FPCs) and boards are connected via relay cable harnesses or by soldering. However, this inevitably leads to additional weight. In addition, the wiring harnesses are difficult to install. Panasonic wants to change this with the CF1 series connector, which was introduced in 2016 and is now in series production. With its structure of metal terminals, which according to the company is unique to date, the connector connects flexible printed circuit boards and printed circuit boards directly with each other. This makes the use of cable harnesses superfluous, according to Panasonic; components and assembly time could be saved.

The robustness of the connector is ensured by a double-clip contact that embraces the metal terminal on the FPC side and the socket on the PCB side. This makes it suitable for use in automotive applications such as LED lights and battery management systems. Another special feature is the inertial locking of the connector, which prevents it from snapping in incompletely.

The CF1 connector is suitable for connecting vehicle lighting such as daytime running lights and rear lights, as well as exterior mirrors, dashboards, cameras and battery management systems.

Panasonic puts the rated current at a maximum of 2.0 A/Pin and the rated voltage at 50 V DC. Further parameters are an insulation resistance of at least 100 MΩ, a contact resistance of at most 20 mΩ (initial) and a dielectric strength of 1000 V AC for 1 minute. The housing holding force is specified as at least 30 N (initial value).
