New Omron FPC/FFC connector offers fast, reliable assembly

Omron Electronic Components Europe has unveiled an FPC/FFC connector featuring a new rotary backlock mechanism for quick, reliable cable insertion, conforming to an industry accepted footprint.

The new XF3M FPC/FFC connector is suitable for connecting LCD panels to printed circuit boards and other board-board connections in applications such as industrial equipment, home appliances, printers, LCD TVs and mobile devices. Omron said that it was expecting strong interest from other applications featuring colour LCD displays, including intercom/security systems, GPS-systems, measurement equipment, medical instruments and healthcare appliances.

The device’s key feature is its new rotary backlock mechanism which offers easier cable insertion, positive confirmation of correct installation and very secure retention of the cable in use. The mechanism is based on a rotary slider for securing the FPC/FFC cable, which is mounted independently from the FPC/FFC socket. A sharp “click” on engagement makes it easy to confirm that the latch is completely locked.

This mechanism enables the socket to be constructed with a four-sided housing that securely holds the FPC/FFC cable for enhanced mounting reliability. With conventional rotary lock connectors, the rotary slider is positioned at the FPC/FFC socket, which means that lifting the cable or applying excessive force may cause the rotary latch to disengage. The design of the new Omron XF3M looks to address these issues.

The connector has a height of 2.0 mm and a depth of 6.4 mm (when locked). The XF3M has a dual contact structure, enabling the cable to be inserted either way up. To simplify insertion, the connector can accept cable inserted at an angle, and will then lock securely to hold the cable in place. It accepts 0.3mm thick FPC or FFC cable, is available in 0.5 mm and 1.0 mm pitches and conforms to a widely used industry accepted board footprint. The moulded parts use LCP (Liquid Crystal Polymer) resins. Its halogen-free construction makes the XF3M environmentally friendly.
