Non-ZIF with Pullforce Locking

20 May 2008

Yamaichi Electronics presents the Non-ZIF connector system with pullforce locking mechanism as an alternative to ZIF connectors.

To improve and simplify handling and process security when plugging FFC/FPC in production, Yamaichi has developed a unique connector system. Commercially available FFC/FPC can be connected with our new non-ZIF with “pullforce” connectors. They are interlocked over a hook mechanism in the connector. Interlocking occurs directly during the plugging process, so that no further cover, drawer or similar steps are needed. This “one push-lock" system simplifies production handling and ensures a secure and permanent connection. An additional and optional stiffener makes the system “Poka Yoke” and avoids plugging errors to 100%.

The special feature of this connector system is the board connector design. The locking mechanism consisting of a row of engagement hooks allows a secure connection between the FFC/FPC and the board connector. Locking happens with the standard supporting tape of the FFC/FPC or optionally via an additional plastic stiffener that is glued to the FFC/FPC. The shape of this additional stiffener does not allow any plugging errors and offers increased vibration security.

The board connectors have a pitch of 0.5 or 1 mm and are available in horizontal and vertical versions. The series will be initially started with 30 contacts for a pitch of 0.5 mm (90°) and 12 to 30 contacts for a pitch of 1.0 mm (90° and 180°). Other pin counts are in development. Various platings such as gold plating are possible on customers’ wishes. Board connectors are available as tape and reel packaging units. For mounting, pick and place caps are available.

If there is a need for the use of an additional stiffener, Yamaichi offers the complete assembly of the FFC/FPC with the additional stiffener. Using the supporting tape as a locking option, allows all commercially available FFC/FPC within certain dimensions and tolerances to be used.

With the non-ZIF connector system with pullforce locking mechanism, Yamaichi offers an extremely interesting and economical alternative to ZIF connectors. This new generation of non-ZIF connectors opens new possibilities for simpler, faster and also more secure assembly of board-to-cable connections.
