Abstract: A complex coupler for cold cathode fluorescent lamp (CCFL) is used as a lamp lead wire coupling terminal, which includes a main body, a CCFL socket, and a cable socket. The main body is in the shape of an elongated column with a complex structure consisting of an inner conductive body and an outer enclosing insulative layer. The main body has a lamp coupling surface, on which the CCFL socket is formed for receiving an end of a CCFL and a lamp lead wire provided on that end of the CCFL, and a conductor coupling surface, on which the conductor socket is formed for a cable to connect thereto. The lamp lead wire of the CCFL and the cable can be electrically connected to each other via the lamp lead wire coupling terminal.
