This is a HDMI Cable icon. We've made it in iOS style, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 12,300 icons, all in the same style and quality.
This icon is depicting an HDMI cable or plug and is distinguished by the presence of a micro-chip in place of where prongs would typically be. The base of the plug is a trapezoid shape and leading out of the plug is a wire.
