Flat Flex & Ribbon Jumper Cables: Introduction Flat Flex and Ribbon Jumper Cables are two types of cable assemblies used for electrical connections across a range of industries, from high-density computer installations to the automotive industry, even aerospace. A flat flex cable assembly, often referred to as flat flex cable, or simply flat cable, is a type of flat ribbon-like cable that is usually multi-layered, with a PVC outer jacket and shielded or unshielded wire. The flat flex cable assembly combines the flexibility of concentric stranded wires and shields with the strength of a solid mass of conductors, bringing the benefits of both to the applications they are used in. A ribbon jumper cable is a multi-conductor cable consisting of multiple wires or conductors in an array arranged in parallel. Each conductor is typically twisted individually, allowing for greater flexibility in routing compared to a flat flex cable. The ribbon jumper cables are often sheathed in a flexible jacket that protects the wires from external interference or physical damage. Application Field Both flat flex and ribbon jumper cables are ideal for applications that require flexibility and the ability to connect different points on a device or system. Common uses for these cables include computer and automotive wiring, aerospace instrumentation, medical equipment, and more. Flat flex cables are used in high-density applications such as disk drives, control box wiring, and consumer electronics. Ribbon jumper cables are used in a wide variety of applications including LED lighting, home entertainment systems, doorbells, and audio systems. Flat flex cables are used in applications where the cable needs to be routed around tight corners or through narrow openings. The flat profile of the cable allows it to bend easily while still maintaining a good connection. They are also used in equipment that has shifting parts or needs to move due to vibration, as the flexibility of the cable will help it withstand such movement. Ribbon jumper cables provide a higher level of flexibility than flat flex cables, and as such are preferable in applications that require frequent wiring changes or rearrangements. This makes them ideal for LED lighting, home entertainment systems, and audio equipment, as it allows for quick and easy changes without the need for major reworking. Working Principle The working principle behind flat flex and ribbon jumper cables is the same as any other type of cable assembly: each of the conductors is coated in an insulating material, and the entire assembly is protected from external interference or physical damage with a protective jacket. The difference between the two is the physical arrangement of the conductors: flat flex cables have conductors arranged in a flattened ribbon, while ribbon jumper cables have conductors arranged in an array. Flat flex cables are constructed by taking multiple strands of insulated wire and then weaving them together in a flattened shape. This provides flexibility while still maintaining a good connection. Ribbon jumper cables are constructed by taking multiple strands of insulated wire and twisting them together into an array. This provides greater flexibility than a flat flex cable, as the individual conductors can be more easily rearranged. Conclusion Flat flex and ribbon jumper cables are two types of cable assemblies used widely in a range of industries from computer installations to aerospace. Each type of cable has its own advantages and disadvantages, depending on the application. Flat flex cables offer flexibility while still maintaining a good connection, while ribbon jumper cables provide greater flexibility for applications that require frequent wiring changes.
