Apple News: Cable assemblies conveying high speed signals while providing reduced signal noise, radiation, and susceptibility to interference.

HDMI cables have quickly become the global standard for connecting high-def equipment audio/video equipment. HDMI is widely recognized as the best all-digital interface delivering both quality and ease of use. Most of the largest consumer electronics, PC and mobile device manufacturers incorporate HDMI connectivity into their products.

So, it should come as no surprise that a new Apple patent was recently published having the following title and abstract:

Ground bar for micro-coaxial wires in hdmi cables

Cable assemblies that may convey high speed signals while providing reduced signal noise, radiation, and susceptibility to interference. These and other examples may be readily manufactured. These and other examples may provide cables having a reduced thickness.

From the patent application, Apple provides the following example of what they’re seeking to capture: An illustrative embodiment of the present invention may provide cable assemblies having a reduced thickness by providing an internal strain relief for the cable. This may eliminate the need for a conventional strain relief that typically wraps around an outside jacket of a cable. These and other embodiments of the present invention may provide a cable having hollow tube in or near its center. The hollow tube may have one of a number of different cross-sections. For example, the hollow tube may have a star-shaped cross section, a circular cross-section, or other shaped cross-section. Stiffening rods may be inserted into the ends of hollow tube. The stiffening rods may prevent the cables from being bent at a localized point and may instead distribute the bend radius over the length of rod. In these and other embodiments of the present invention, the hollow tube and rod may be replaced by a plastic or nylon rod. In these and other embodiments of the present invention, these hollow tubes and rods may be in or near a center of the cable or elsewhere in or on the cable.

The patent application was published on August, 3, 2017 – and has the following publication number: US 2017/0221604 A1.
