Flat Flex, Ribbon Jumper Cables

Flat Flex and Ribbon Jumper Cables are two forms of flexible cable often used in the electronics industry. Depending on application, one form may be better than the other. This article will discuss the applications and working principles of Flat Flex and Ribbon Jumper Cables.

Flat Flex Cable

Flat Flex Cable is constructed of multiple strands of wires insulated with flexible polyurethane. This method of construction allows the cable to be bent and twisted in tight spaces without kinks or compression. Flat Flex Cable is especially useful in applications where cables must be placed in confined spaces, such as in manufacturing equipment and robotics. Additionally, Flat Flex Cable is commonly used to reduce the concentrations of electromagnetic fields in close proximity to electrical circuits.

Working Principle of Flat Flex Cables

Flat Flex Cables use a unique method of connecting the conductors to one another called differential impedance. Differential impedance is the difference in voltage between two points along the cable, which allows the cables to flexibility and helps reduce the effects of electromagnetism on the circuit. Each conductor is connected to each other using a layer of plastic insulation, which is then covered with an aluminum foil shield. The shield helps provide protection to the conductors from external electrical interference.

Ribbon Jumper Cable

A Ribbon Jumper Cable is composed of an array of wires that are twisted into a flat shape. The wires are typically composed of copper, aluminum, or a combination of both. Ribbon Jumper Cables are often used in applications where there are a large number of wires packed into a small space, such as in telecommunications or computer systems.

Working Principle of Ribbon Jumper Cables

The wires of the Ribbon Jumper Cable are twisted into a flat shape and then subjected to a high-temperature fusion process to create the flexible flat rope. This fusion process embeds the wires in a polyurethane coating that increases its flexibility. The coating also helps reduce the effects of electromagnetism on the circuit. The wires in the cable are connected by further binding them with a conductive adhesive.

Conclusion

In conclusion, Flat Flex and Ribbon Jumper Cables have a variety of applications in the electronics industry. Depending on the requirements of the application, one form may be better than the other. Flat Flex Cables use the principle of differential impedance to achieve electrical connection between wires while the principle of fusion connections are used in Ribbon Jumper Cables. Both Flat Flex and Ribbon Jumper Cables offer many benefits including improved flexibility, reduced EMI radiation, and better protection from external electrical interference.
