Description

Focus Pack Cable Fastening for Flyback Transformer

The present invention relates to a focus pack cable fixing structure of a flyback transformer, and more particularly, a cable that is connected to a clip terminal provided inside the case to supply a focus voltage or a screen voltage to the cathode ray and more robust. The present invention relates to a focus pack cable fixing structure of a flyback transformer, which is improved to be secured.

In general, a flyback transformer refers to a single winding transformer for obtaining a high pressure for a water pipe using pulses generated during the return period of a horizontal deflection output in a television receiver. The focus pack is coupled to the outer circumferential surface of the housing.

At this time, the focus pack is connected to a high-voltage terminal provided inside the housing to exchange a predetermined focus voltage and screen voltage obtained by adjusting the focus knob and screen knob with a cathode ray ube through a cable. Do this.

Referring to FIGS. 1 and 2, a focus pack cable fixing structure of a flyback transformer according to the related art for performing the above function is as follows.

1 is an exploded perspective view illustrating a focus pack cable fixing structure of a flyback transformer according to the prior art, and FIG. 2 is a cross-sectional view illustrating main parts of the focus pack cable fixing structure of the flyback transformer according to the prior art.

As shown in FIGS. 1 and 2, the substrate 111 is accommodated in the case 110 of the focus pack 100, and the cable 120 includes a fixing part protruding from the case 110. It is inserted into the fixing hole 113a of the 113 and the end thereof is coupled to the structure in which the spiral portion 121 is fitted to the clip terminal 112 electrically connected to the substrate 111.

At this time, one end of the clip terminal 112 is in electrical contact with the substrate 111, and supplies the focus voltage obtained in cooperation with the circuit disposed on the substrate 111 to the outside through the cable 120. It performs the function.

By the way, the focus pack 100 of the flyback transformer according to the prior art has a fixed structure of the cable 120, the clip terminal 112 that makes an electrical connection with the substrate 111 is the other than the spiral portion 121 of the cable 120 It has a function of clamping the spiral part 121 of the cable 120 so that the spiral part 121 of the cable 120 does not fall in the reverse direction because it has a tooth that clips the circumference, but it may be caused by external impact or contact during the assembly of the flyback transformer. When the cable 120 is rotated even a little, the outer circumference of the spiral portion 121 is easily damaged by the teeth of the clip terminal 112 or easily detached from the clip terminal 112, so that the electrical contact state is very high. It caused a problem of being poor.

Accordingly, the present invention was devised to solve the above problems, and the object of the present invention is to fix a cable for performing a function of exchanging a focus voltage or a screen voltage with a cathode ray tube, and the fixing hole of the fixing part, and the fixing hole. The present invention provides a focus pack cable fixing structure for a flyback transformer configured to be elastically coupled and coupled through a fastening groove of a holder protrudingly formed on a surface of a case which is disposed obliquely from a case.

The present invention for achieving the above object includes a clip terminal for making an electrical connection to the substrate, and a case in which the fixing portion having a fixing hole on the surface protruding molded so that the spiral portion of the cable can be connected to the clip terminal In a focus pack cable fixing structure of a flyback transformer, the ring-shaped fastening groove of which one side is opened to protrude into the surface of the case which is diagonally positioned from the fixing hole of the fixing part so as to receive the cable is fitted. It comprises a holder having a as a basic feature on the technical configuration.

Hereinafter, a preferred embodiment of the focus pack cable fixing structure of the flyback transformer according to the present invention will be described with reference to FIGS. 3 and 4.

3 is a perspective view illustrating a focus pack cable fixing structure of a flyback transformer according to the present invention, and FIG. 4 is a cross-sectional view illustrating main parts of the focus pack cable fixing structure of a flyback transformer according to the present invention. About the same structure which performs the same function, the same name and the same code | symbol are used together.

The focus pack 100 of the flyback transformer according to the present invention is fixed to the cable 120, as shown in FIGS. 3 and 4, the substrate 111 for implementing the focus voltage and the screen voltage, and the substrate ( The clip terminal 112 which makes an electrical connection to 111 and the fixing part provided with the fixing hole 113a in the surface so that the spiral part 121 of the cable 120 may be fitted to the clip terminal 112. 113 is made of a case 110 protruded.

At this time, the ring-shaped tightening groove 114a of which one side is opened so that the cable 120 can be inserted into the surface of the case 110 positioned diagonally from the fixing hole 113a of the fixing part 113. A holder 114 having a) is protruded and provided.

In addition, the diameter of the ring-shaped tightening groove 114a is equal to or slightly smaller than the diameter of the cable 120 to maximize the fixing force of the cable 120.

Referring to the operation and effect of the focus pack 100 cable 120 fixed structure of the flyback transformer according to the present invention made of the above configuration.

First, the assembly of the substrate 111 and the clip terminal 112 in the case 110, and then the cable 120 so that the spiral portion 121 of the cable 120 can be connected to the clip terminal 112 Push in the grooves 113a of the fixing part 113.

In this case, the cable 120 is naturally connected to the clip terminal 112 via the fixing hole 113a and is closely attached to the inner circumference of the fixing hole 113a.

Thereafter, the cable 120 is directed toward the tightening groove 114a of the holder 114 protrudingly formed on the surface of the case 110 positioned diagonally from the fixing hole 113a of the fixing part 113. At the same time, the cable 120 is pushed into the inner circumference of the tightening groove 114a so as to be elastically tightened, thereby allowing the assembly to be completed.

Here, the fixing hole 113a of the fixing part 113 is connected to the clip terminal 112 provided inside the case 110 and performs a function of exchanging a focus voltage or a screen voltage with a cathode ray tube. By pulling out from the elastically fixed to the insertion groove (114a) of the holder 114 in a curved state, the pulling force of the cable 120, that is, the repulsive force against the tensile force can be generated during assembly of the flyback transformer In addition, the fixing force can be further improved, and when the cable 120 is pressed toward the clip terminal 112 by external contact, the fastening groove 114a and the fixing portion 113 of the holder 114 are also provided. It is possible to minimize the influence on the clip terminal 112 through the support force by the fixing hole (113a) of the.

As described above, according to the fixation structure of the focus pack 100 cable 120 of the flyback transformer according to the present invention, it is connected to the clip terminal 112 provided inside the case 110 and the focus voltage or the screen voltage is negative. The holder 120 protruded and formed on the surface of the fixing hole 113a of the fixing part 113 and the case 110 located in an oblique direction from the fixing hole 113a to perform the function of communicating with the pipe (120). By configuring the elastic fastening coupling through the fastening groove 114a of the 114, it is possible to minimize the rotation and movement of the cable 120 by the pressure input or tensile force due to external impact to improve the reliability of the product There is an excellent effect that can be maximized.
