HDMI wall plates are used to provide a convenient connector for HDMI cables in walls or other surfaces. They typically consist of two parts: a faceplate and a connector module.
The faceplate is a flat, usually rectangular cover that attaches to a wall or other surface. It has a cut-out hole(s) where the connector module(s) can be inserted.
The connector module is the part that actually connects to the HDMI cable(s). It fits into the cut-out holes in the faceplate and protrudes from the surface of the wall. The connector module typically has an HDMI jack on one side to plug the HDMI cable(s) into and screw-in terminals on the other side that attach to the copper wires inside the wall.
When an HDMI cable is plugged into the HDMI jack on the connector module, it provides a direct wired connection between any two devices that are connected to the HDMI cable. This allows you to transmit high-quality audio and video signals between devices such as media players, game consoles, and televisions.
Overall, HDMI wall plates provide a neat and professional way to connect HDMI cables in walls or other surfaces, reducing clutter and minimizing the risk of accidental disconnection.
