52892-1990

FFC and FPC connectors have become common in many electronic systems because of the small size, low cost, and easy assembly. These connectors are designed to facilitate the connection of flexible flat cable (FFC) or flat flexible printed circuit (FPC) to printed circuit boards (PCBs), and they are widely used in consumer electronic devices such as mobile phones, tablets, and laptop computers.

The 52892-1990 standard for FFC/FPC connectors defines the physical characteristics and electrical performance of the connectors, including size and shape, maximum current, insulation resistance, and insertion and extraction force. The connectors are available in a variety of sizes and configurations, including standard, low-profile, ultra-miniature, shielded, and waterproof varieties.

The 52892-1990 standard also provides guidelines for the specific design and application of FFC/FPC connectors, such as hole sizes and spacing, and the use of secure retention devices. Depending on the application, the connectors may be connected directly to the PCB or used with specialized sockets and adapters.

FFC/FPC connectors are typically constructed from copper-clad plastic or stainless steel, which provides a high level of durability and moisture resistance. The contact springs of the connectors, which electrically connect the cable to the PCB, may be made of either copper or phosphor bronze. The cable and contact springs are typically held in place by a latch or other retention device located at the end of the connector.

The typical application field of FFC/FPC connectors is in consumer electronics, as they are often used to connect LCD displays, keypads, sensors, and other components. They are also commonly used in medical equipment, automotive applications, and industrial instrumentation.

The working principle of FFC/FPC connectors is relatively simple. The cable is inserted into the connector, and the latch or retention device is secured to keep the cable in place. Once the cable is in place, the contact springs make electrical contact with the PCB and provide a reliable connection. The cable can then be easily disconnected by releasing the latch.

Overall, FFC/FPC connectors are an essential component in many electronic systems. Thanks to the 52892-1990 standard, they are readily available and reliable, making them an ideal solution for connecting electronic devices.
