ABSTRACT:
An improved plug-in type light bulb including a light bulb with a plug unit and an electrical socket for receiving the light bulb. The socket is comprised of two symmetrical halves each of which includes an upper portion and a lower portion. A cover plate with a notch is disposed inside at the upper portion, while a plurality of grooves are formed at the lower portion. A plurality of electrically conductive plates are disposed in the grooves and each of which has an angular contact terminal. The plug unit has two side walls each of which has an integrally formed raised block and two lateral walls against which the corresponding contact terminals of the lead wires rest. The lateral walls are further provided with a respective half round groove across which the contact terminal is disposed. When the light bulb is inserted into the socket, the angular contact terminals of the conductive plates will fit into the insert grooves of the plug unit of the light bulb and cause a part of the respective contact terminals of the lead wires to fit into the same insert grooves to achieve firm electrical contact.
