Apple working on brittle and defective charging cables

February 9, 2021

Apple would like to rely on more robust charging cables in the future. This emerges from a patent application from the Californian technology group.

Apple wants to increase the robustness of its charging cables. According to a patent reported by the AppleInsider website, Apple is working on several ideas for optimised cables that should not break easily. (Also Read:Unlock the iPhone with a mask without a PIN – New update makes it possible)

Finally, more robust charging cables: that’s Apple’s plan

The group is thinking about cables with variable stiffness values and thickening parts for various cable elements. The cable itself should be evenly thick. It is also planned to replace the so-called “strain relief sleeve”, i.e. the cap at the end of the cable.

New patent aims to solve a known problem with Apple charging cables

Apple itself admits errors in the previous design of the cables: “It is known that bending the cable near the end point can lead to undesirable stress on the wire connections, which in turn can cause cable failure,” says the patent. “Accordingly, it is common to provide a strain relief sleeve made of a stiff material around the end portion of the cable.”

It also says: “The stiff material creates a local increase in the bending resistance of the cable and thus relieves the wire connections,” said Apple. “In addition to locally stiffening the cable, the strain relief sleeve also makes the cable thicker at the ends. In some cases, the extra thickness may not be desirable.”

Seven inventors are working on new cable systems

As “AppleInsider” also reports, the majority of the patent describes possible materials and tries to define their stiffness. A total of seven inventors are named. Apple’s new ideas are based on a mixture of strain relief and thickening. However, the latter caused trouble in the past: After the company had made the Lightning cables a little thicker, they no longer fit in third-party iPhone stands.

Again and again criticism of Apple’s vulnerable charging cables

The fact that Apple’s USB and Thunderbolt cables have a short shelf life and often fray or turn yellow is repeatedly criticised by users. It is not known when a new generation of robust cables will appear.
