0.5 mm pitch FPC/FFC connector withstands assembly errors

November 22, 2016 // By Graham Prophet
Kyocera has developed a robust connector for flexible printed circuit/flexible flat cable (FPC/FFC) application, with 0.5 mm-pitch contact pitch, that reduces breakage from improper insertion.

Kyocera Connector Products’6811 Series FPC/FFC connector is designed to meet the need in smartphones and related devices for smaller, thinner FPC/FFC connectors. These connectors require delicate handling in the assembly process and may be damaged by improper insertion or unintentional manual contacts with certain parts. Kyocera’s highly robust 6809 Series electronic connectors, introduced in 2014, were designed with this challenge in mind.

 

The 6811 Series follows the same concept, but has been enhanced with even more robust features. It has a pitch of 0.5 mm, profile height of 1.28 mm, and is available in 4 to 16 pins. The 6811 Series connector features bottom contacts, a front locking mechanism, and connects applicable FPC/FFC with a thickness of 0.3 mm. Despite its space-saving profile and low pin counts, robustness has been enhanced with metal brackets which prevent cables from being lifted up out of the connector. In addition, the 6811 helps increase assembly efficiency by using tabbed FPC/FFC, preventing contact misalignment from oblique or shallow insertions and enabling visual confirmation of correct insertion.

 

An actuator locks FPC/FFC with tabbed cables ensures reliable connection even if the FPC/FFC is pulled forcibly, minimizing or eliminating the likelihood of deforming the contacts or connector structure. Accepting FPC/FFC thickness of 0.3 ±0.03 mm, the contacts are rated at 0.5A/50V DC.

Operating temperature range is -40 to +85℃.
