Description

Core fixing structure of high pressure generator

The present invention relates to a core fixing structure of the high-pressure generator, and more particularly, to form a plurality of fixing jaws on the inner end of the guide piece formed spaced apart from each other on the upper and lower surfaces of the molding case so that the upper and lower ends of the plurality of cores can be closely fixed. It relates to a core fixing structure of a high pressure generator.

In general, a high voltage transformer (flyback transformer) 100 is a single-circuit transformer for obtaining a high pressure for the water pipe by using a pulse generated in the return period of the horizontal deflection output in the television receiver, which accommodates the low pressure bobbin and the high pressure bobbin therein. A molding case 110 is provided, and a focus pack 120 for adjusting a predetermined focus voltage and a screen voltage is coupled to an outer circumferential surface of the molding case 110.

Referring to FIG. 1, the structure of the high pressure generator according to the related art for performing the above function is as follows.

1 is an exploded perspective view showing a high pressure generator according to the prior art.

As shown in FIG. 1, the high pressure generator 100 according to the prior art inserts the cores 130a and 130b up and down the core insertion holes 111 formed in the molding case 110, and then the cores. The core fixing band 140 is elastically assembled to the engaging grooves 131a and 131b formed on the outer circumferential surfaces of the 130a and 130b, respectively, to form the structure for coupling the plurality of cores 130a and 130b.

At this time, a plurality of guide pieces 112a, 112b are formed on the upper and lower surfaces of the molding case 110 to support the plurality of cores 130a, 130b, and the core fixing band. The 140 is formed in a substantially Hangul consonant deformed shape and has an elastic force that pushes the plurality of cores 130a and 130b inward. The inward elastic force acts to press the two cores 130a and 130b fitted to the core insertion hole 111 of the molding case 110 in a direction facing each other to closely fix each other.

However, the core fixing structure of the high pressure generator according to the prior art as described above is inserted into the core (130a, 130b) in the core insertion hole 111 of the molding case 110, the core fixing band 140, Due to the elastic fixing of the cores (130a) and (130b), not only the number of workmanships increase, but also the manufacturing cost due to the excessive number of parts increases significantly, resulting in a drop in productivity.

Accordingly, the present invention has been made to solve the above problems, the purpose of which is to form a mutually spaced molding on the upper and lower surfaces of the molding case to achieve a close coupling with the molding case in the exact position where the core should be located It is to provide a core fixing structure of the high-pressure generator formed with a plurality of fixing jaw on the inner surface end of the guide piece.

The present invention for achieving the above object is a molding case in which a plurality of guide pieces spaced apart from each other on the upper and lower surfaces protruded and the core insertion hole is formed through the center, and the plurality of guide pieces are supported by the plurality of guide pieces to be fitted up and down the core insertion hole In the core fixing structure of the high-pressure generator comprising a plurality of cores are formed, protruding in a direction facing each other to the ends of the plurality of guide pieces formed to be spaced apart from each other on the upper and lower surfaces of the molding case to support and fix the upper and lower ends of the plurality of cores What is provided with a plurality of fixing jaw is a basic feature of the technical configuration.

Hereinafter, a preferred embodiment of the core fixing structure of the high pressure generator according to the present invention with reference to 2 and 3 as follows.

Figure 2 is an exploded perspective view showing a high pressure generator according to the present invention, Figure 3 is a front view for explaining the core fixing structure of the high pressure generator according to the present invention.

In the high pressure generator 100 according to the present invention, as shown in FIGS. 2 and 3, a plurality of guide pieces 112a and 112b spaced apart from each other on the upper and lower surfaces are protruded and have a core insertion hole 111 at the center thereof. The molded case 110 is formed through and a plurality of cores (130a, 130b) to be fitted up and down of the core insertion port 111.

At this time, the inner surface ends of the plurality of guide pieces 112a, 112b formed on the upper and lower surfaces of the molding case 110 are protruded in a direction facing each other to form the plurality of cores 130a, 130b. A plurality of fixing jaw (112a '), 112b' for supporting the upper and lower ends of the is provided.

Referring to the assembly operation of the core fixing structure of the high pressure generator according to the present invention made of the above configuration.

First, after assembling the high-pressure bobbin and the low-pressure bobbin inside the molding case 110, the plurality of cores 130a and 130b are pushed up and down in the direction facing each other up and down by the core insertion holes 111.

At this time, the plurality of cores 130a and 130b are supported by guide pieces 112a and 112b spaced apart from each other on the upper and lower surfaces of the core insertion hole 111, and the plurality of guide pieces 112a and ( Fixing jaws 112a 'and 112b' protruded in a direction facing each other are provided at the ends of the inner surface of the 112b to support the upper and lower ends of the cores 130a and 130b, respectively.

Thereafter, the epoxy may be filled in the molding case 110 to complete final assembly of the high pressure generator 100.

Here, the core fixing structure of the high-pressure generator according to the present invention, the upper and lower ends of the core (130a, 130b) is fixed to the fixing jaw (112a '), 112b' of the guide pieces (112a), (112b) by The cores 130a and 130b may be tightly coupled with the molding case 110 at the exact position where the cores 130a and 130b are to be positioned, and the core 130a and 130b may be prevented from being changed in the assembly process until the epoxy is filled. It is possible to not only improve the assemblability of the core, but also does not require a separate component such as the core fixing band 140 for supporting the core (130a, 130b), the production cost is low, the core fixing band ( 140) It can be seen that there is a useful action that can eliminate the inconvenience during assembly.

According to the core fixing structure of the high-pressure generator according to the present invention as described above, by forming a plurality of fixing jaws on the inner surface end of the guide piece formed to be spaced apart from each other on the upper and lower surfaces of the molding case so that the upper and lower ends of the plurality of cores can be tightly fixed. As a result, it is possible to achieve a tight coupling with the molding case at the exact position where the core is to be located and to prevent the core from changing during the assembly process until the epoxy filling, and to fix the core to support the core. There is no need for a separate component such as a band, which has an excellent effect of greatly improving assembly and productivity.
