P203 L-type plug for solderless model. The plug shaft is entirely 24-karat gold plated, and the cable is tightened using the needle at the rear of the plug and the two screws (utility model) at the plug cap to pass the signal. In addition, by firmly tightening these two screws, concerns about poor contacts are eliminated, and the structure prevents problems that are common with conventional products, such as the cable coming off the plug.
