Installation structure of the flyback transformer

The present invention relates to an installation structure of a flyback transformer, and more particularly, to an installation structure of a flyback transformer that enables to install a flyback transformer on a substrate.

In general, a flyback transformer is a high-pressure generator for supplying high-voltage power to a cathode-ray tube (CRT). The flyback transformer is composed of a coil for winding a low pressure bobbin, a high pressure bobbin, a low pressure bobbin and a high pressure bobbin. The high pressure generator is coupled to the substrate, which is conventionally installed on the substrate through a pin installed in the low pressure bobbin. In this regard, the structure of the conventional flyback transformer will be described with reference to FIGS. 1 and 2.

1, a high pressure bobbin 10 is shown. Ribs 12 are formed on the outer circumferential surface of the high-pressure bobbin 10 so as to easily wind the coil, and a plurality of diodes 16 are provided through the diode support 14, respectively. The inside of the high pressure bobbin 10 is empty and the low pressure bobbin 20 is inserted therein.

The low pressure bobbin 20 has a core insertion hole 22 into which one side of the core is inserted.

At one end of the low pressure bobbin 20, a plurality of pin supports 24 are arranged radially. The pins 26 are provided on the pin support 24, respectively. The pin 26 is connected to the coil wound around the outer circumferential surface of the low-pressure bobbin 20 and inserted into a hole formed in the substrate to serve to install the flyback transformer on the substrate.

The case 30 is shown below the high pressure bobbin 10 and the low pressure bobbin 20. The case 30 accommodates and protects the low pressure bobbin 20 and the high pressure bobbin 10 therein and is filled with an insulating material such as epoxy.

The flyback transformer including the low pressure bobbin 20, the high pressure bobbin 10, the case 30, and the like is assembled to the substrate 40 as shown in FIG. 2 in a completed state, as shown in the substrate 40. Likewise, a plurality of holes 42 are formed. The holes 42 are formed at positions corresponding to the pins 26, respectively, and are the portions into which the pins 26 respectively provided in the low pressure bobbin 20 are inserted. Of course, after the pin 26 is inserted, soldering is performed to make electrical connection between the flyback transformer and the substrate 40.

That is, conventionally, each pin 26 provided in the low-pressure bobbin 20 is inserted into the hole 42 of the substrate 40 and soldered, respectively, so that a flyback transformer is installed on the substrate 40. When the flyback transformer is installed as a trapped process, if a defect occurs in the flyback transformer or the substrate 40 during the installation process, the substrate 40 and the flyback transformer must be dismantled. . As a result, when a failure occurs, the substrate and the flyback transformer are disposed of.

An object of the present invention is to provide a flyback transformer, which can be easily separated from the substrate if a failure occurs when the flyback transformer is installed on the substrate. To provide a mounting structure of the transformer.

An object of the present invention is to install a flyback transformer having a low-pressure bobbin having a flyback transformer to the substrate, the low-pressure bobbin is arranged along the outer peripheral surface at a predetermined angle intervals and a groove of a predetermined depth is formed A plurality of supports, conductive rubber inserted into the groove, coupled to the support and the conductive rubber is connected to one side and the other side protrudes to the outside of the support board and the coil corresponding to the coil wound on the outer circumferential surface of the low-pressure bobbin respectively corresponding to the substrate It can be achieved by the installation structure of the flyback transformer, characterized in that it comprises a fixing pin installed to protrude upwards and plugged into the conductive rubber, respectively.

Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the present invention in detail.

The high pressure bobbin 110 is coupled to the low pressure bobbin 120. A core insertion hole 122 is formed inside the low pressure bobbin 120, and a plurality of support stands 124 are formed at one end thereof. As shown in Fig. 4, the support 124 is provided with grooves 125 having a predetermined depth, and the groove 125 is provided with a conductive rubber 126. In addition, the support pin 124 is coupled to the bending pin 127 is connected to the conductive rubber 126. One end of the bending pin 127 protrudes outward of the support 124, which is a part respectively connected to the coil wound around the outer circumferential surface of the low pressure bobbin 120. Of course, you may use the thing of the form of a tear instead of this bending pin 127. This is because it can be connected to the coil wound around the low-pressure bobbin 120.

The case 130 is shown below the low pressure bobbin 120 and the high pressure bobbin 110.

The case 130 accommodates and protects the high pressure bobbin 110 and the low pressure bobbin 120 therein and allows other components to be installed. The case 130 is filled with epoxy or the like.

The fixing pin 144 is to allow the flyback transformer to be installed, respectively, it must be installed at positions corresponding to the support 124 installed in the low-pressure bobbin 120 of FIG.

The fixing pin 144 is inserted into the conductive rubber 126, thereby making electrical connection between the flyback transformer and the substrate 140. The fixing pin 144 may be formed by forming a hole in the substrate 140 and inserting it downward from the substrate 140 and soldering the lower surface of the substrate 140. This can be seen from FIG.
