0150201064 Application Field and Working Principle

Flat Flex cables are a type of ribbon jumper cables used for connecting multiple conductors in an electrical circuit, such as between a motherboard and a processor. A flat flex cable is formed by taking multiple strands of insulated wires, typically of 30 to 48 in thickness, and arranging them in parallel at regular intervals. This creates a flat shape that can be easily interfaced with a circuit board. The cables are usually made of electrical grade polyvinylchloride, PVC, which is resistant to heat, moisture, and wear.

Applications

Flat flex ribbon jumper cables are used in a wide variety of applications. They are most commonly used in computer and electronic circuits, such as in the connection between a motherboard and a processor. The cables are also used in digital video cameras, television camera systems, traffic light controllers, and other electronics. In addition, they are commonly used in the fabrication of wiring harnesses and the connection of various electrical components.

Working Principle

Flat flex cables are typically constructed from multiple strands of insulated wire. The number of strands per cable can range from two to hundreds, with the number of strands per cable increasing with larger current ratings. The insulation used between each strand of wire may vary, but it is typically rated for voltages up to 250 volts. Each strand is separated from the other by a gap, or spacing. This spacing ensures that the electrical signals are not interrupted when the cable is bent or twisted.

The flat flex cables are then attached to a connector, such as a terminal block, using a soldering process. Once the connectors are attached, the terminals on the connector are then aligned so that each strand of wire is properly connected. The final step is to secure the connector to the flat flex cable using a spacer. This prevents the terminals from coming loose, due to the internal strain created by the cable twisting.
