A cable with braided silicon dioxide fibers as dielectric core
A recently filed patent (Publication Number: US20230298783A1) describes a new type of cable design that includes a center conductor, a dielectric core layer made of silicon dioxide fibers, and an outer conductor layer. The dielectric core layer is braided around the center conductor to form a braided dielectric core layer. The outer conductor layer is then formed over the braided dielectric core layer.
The cable may also include additional layers such as a strength member layer and a jacket layer. The strength member layer is formed over the outer conductor layer, providing additional support and durability to the cable. The jacket layer is then formed over the strength member layer, further protecting the cable from external elements.
The braided dielectric core layer may consist of multiple sublayers of silicon dioxide fibers, which are braided successively over the center conductor. These sublayers may be braided using different braiding parameters to ensure improved coverage of the braided dielectric core layer over the center conductor.
The outer conductor layer can be formed using different methods. In one embodiment, a conductive tape, which may include copper or stainless steel layers, is wrapped around the braided dielectric core layer. In another embodiment, a semi-rigid conductive tube is used as the outer conductor layer, with the center conductor and braided dielectric core layer inserted inside the tube.
The patent also describes a method for manufacturing the cable. The method involves braiding the silicon dioxide fibers around the center conductor to form the braided dielectric core layer. An outer conductor layer is then formed over the braided core layer to complete the cable. The method may also include the formation of a strength member layer and a jacket layer, similar to the cable design.
Overall, this patent introduces a new cable design that incorporates a braided dielectric core layer made of silicon dioxide fibers. This design aims to improve the coverage and performance of the cable, making it suitable for various applications that require reliable and efficient signal transmission.
