After the socket body is respectively inserted into the assembly holes of a base plate, a metal plate is used to put the wick of each lamp tube into the socket body, and then weld it to the socket body. The metal plates are welded for electrical continuity. This kind of method requires another metal plate to be welded, which greatly increases the cost, and the welding method also makes the manufacturing process complicated.
