* 도면의 주요부분에 대한 부호의 설명* Explanation of symbols for main parts of the drawings

1 : 케이스 2 : 저압보빈1 case 2 low pressure bobbin

3 : 패라이트코아 삽입부 3a : 고정편3: ferrite core insertion part 3a: fixed piece

4 : 페라이트 코아 4a : 단부4: ferrite core 4a: end

본 고안은 텔레비젼 수상기에 사용되는 플라이백 트랜스 포머에 관한 것으로, 특히 저압보빈에 페라이트 코아 고정돌편을 형성하여 페라이트 코아를 접착제를 사용하지 않고 고정하도록한 플라이백 트랜스 포머의 페라이트 코아 고정장치에 관한 것이다.The present invention relates to a flyback transformer used in a television receiver, and more particularly, to a ferrite core fixing device of a flyback transformer in which a ferrite core fixing stone piece is formed in a low pressure bobbin to fix the ferrite core without using an adhesive. .

종래 플라이백 트랜스에 있어서는 페라이트 코아(4)를 저압보빈(2)에 조립한 후 페라이트 코아(4)를 고정시키기 위해서 접착제(8)를 도포하고 있다.In the conventional flyback transformer, after the ferrite core 4 is assembled to the low pressure bobbin 2, the adhesive 8 is applied to fix the ferrite core 4.

따라서 종래 플라이백 트랜스 포머의 페라이트 코아 고정구조에 있어서는 페라이트 코아(4)를 고정시키기 위하여 접착제(8) 도포공정이 요구되므로 조립성이 저하되고 접착제의 사용으로 인하여 원가가 증가되었으며, 접착부분이 떨어지면 페라이트 코아(4)가 상하로 움직이게 되므로 불량의 원인이 되는 것이었다.Therefore, in the ferrite core fixing structure of the conventional flyback transformer, since the adhesive 8 coating process is required to fix the ferrite core 4, the assembly performance is reduced and the cost is increased due to the use of the adhesive. Since the ferrite core 4 moved up and down, it was a cause of the defect.

본 고안은 이와같은 종래의 결함을 해소하기 위하여 안출한 것으로, 플라이백 트랜스 포머의 페라이트 코어를 고정시키기 위한 페라이트 고정용 돌편을 저합보빈의 페라이트 코아 삽입부에 형성하여 페라이트 코아를 간편용이하게 고정할 수 있도록한 것인바, 이를 첨부한 도면에 의하여 상세히 설명하면 다음과 같다.The present invention has been devised to solve such a conventional defect, and the ferrite fixing protrusion for fixing the ferrite core of the flyback transformer is formed on the ferrite core insertion portion of the low hop bobbin to easily fix the ferrite core. The bar will be described in detail with reference to the accompanying drawings.

제1도는 본 고안 장치가 적용된 플라이백 트랜스 포머의 개략 분해 사시도이고, 제2도는 동상의 체결상태를 보인 측면도로서, 이에 도시한 바와같이, 케이스(1)에 내장된 저압보빈(2)의 페라이트 코아 삽입부(3)를 통하여 페라이트 코아(4)를 삽입 고정한 것에 있어서, 상기 저압 보빈(2)의 페라이트 코아 삽입부(3) 내주면 양측부에 탄성 고정편(3a)을 형성하여 페라이트 코아(4)의 단부(4a)가 양측 고정편(3a)에 걸려 지지되게 하여서 된 것으로서, 도면에서 미설명 부호5는 포커스팩, 6은 애노드캡, 7은 터미널핀을 각각 보인 것이다.1 is a schematic exploded perspective view of a flyback transformer to which the device of the present invention is applied, and FIG. 2 is a side view showing a fastening state of an in-phase, and as shown therein, a ferrite of a low pressure bobbin (2) embedded in a case (1) In the case where the ferrite core 4 is inserted and fixed through the core inserting portion 3, an elastic fixing piece 3a is formed at both sides of the inner circumferential surface of the ferrite core inserting portion 3 of the low pressure bobbin 2 to form a ferrite core 4 End portion 4a of the) is to be supported by both fixing pieces (3a), 5 in the drawing, 5 is a focus pack, 6 is an anode cap, 7 is a terminal pin.

이와같이된 본고안은 페라이트 코아(4)가 저압보빈(2)에 조립된 후 삽입부(3) 내주면에 형성된 페라이트 코아 고정편(3a)에 단부(4a)가 걸려지지되어 상하로 움직임이 없이 견고하게 고정된다.In this way, the ferrite core 4 is assembled to the low-pressure bobbin 2, and then the end 4a is hung on the ferrite core fixing piece 3a formed on the inner circumferential surface of the insert 3 so that it is firmly moved up and down. Is fixed.

이상에서 설명한 바와같은 본 고안은 종래에 사용하였던 접착제가 불필요하게 되므로 원가절감을 가져오며 접착제 도포 고정이 없어지므로 작업공정의 단축을 기할 수 있게되며, 접착 부분이 떨어져 페라이트 코아가 상하로 유동됨으로 인한 불량율을 감소할 수 있게 되는 이점이 있다.As described above, the present invention can reduce the cost of the adhesive used in the related art and eliminate the fixing of the adhesive, thereby shortening the work process, and due to the drop of the adhesive part, the ferrite core flows up and down. There is an advantage that the failure rate can be reduced.
