Synchronous cable coupling device of fly back transformer

Abstract

A coupling device of synchronous cable for connecting a frequency of an induced voltage generated from a fly back transformer (FBT) is provided. The coupling device includes a metal support 53 formed with an accommodating groove 52 so as to be interposed with a shield metal 51 to a front wall surface of a case 50 of the FBT. Case 50 is provided with a ferrite core 60, and the ferrite core 60 is inserted and supported between the metal support 53. Shield metal 51 of the metal support 53 is connected with a synchronous cable 70 and grounded so as to draw out an induced voltage of the FBT. According to this design, not only a frequency of the induced voltage generated from the FBT is made to be stably drawn out, but also the coupling of the synchronous cable is automated whereby its workability and a productivity are improved. In addition, the synchronous cable is coupled and fixed in a firm state, movement of the synchronous cable is prevented, and a frequency of the synchronous signal and an operating frequency of the FBT can be effectively stabilized.
