Description

몰딩수지의 넘침 수납구조를 가지는 일체형 보빈Integral bobbin with overflow storage structure of molding resin

본 고안은 디스플레이 장치용의 플라이백 트랜스에서 동선이 권선되는 보빈에 관한 것으로서 특히, 저압보빈과 고압보빈이 일체형으로 구성되고, 또 이 일체형 보빈의 에폭시 수지 몰딩시에 코어 삽입부로 넘쳐흐른 수지를 수납하여 코어 삽입시 여기에 넘친 수지가 장애가 되지 않도록 해주는 몰딩수지의 넘침 수납구조를 가지는 일체형 보빈에 관한 것이다.The present invention relates to a bobbin in which a copper wire is wound around a flyback transformer for a display device. In particular, a low-pressure bobbin and a high-pressure bobbin are integrally formed, and when the epoxy resin is molded in the integral bobbin, the resin overflowed to the core insertion part is stored. The present invention relates to an integral bobbin having an overflowing storage structure of a molding resin that prevents the overflowed resin from interfering with the core insertion.

종래의 플라이백 트랜스 보빈 구조를 도1에 나타내었다.The conventional flyback trans bobbin structure is shown in FIG.

일체형 보빈(1)으로서; 저압코일이 권선된 외주면에 절연필름과 함께 고압코일을 권선하여 코일부(2)가 이루어지고, 보빈의 상단에 페라이트 코어 삽입부(3)가 형성됨과 함께 코어 삽입면(4)이 이루어져서 이 곳에 페라이트 코어(5)가 삽입되어 그 일단면(5a)이 접하게 된다.As integral bobbin 1; The coil part 2 is formed by winding a high pressure coil together with an insulating film on the outer circumferential surface of which the low pressure coil is wound, and a ferrite core inserting part 3 is formed on the upper end of the bobbin and a core inserting surface 4 is formed there. The ferrite core 5 is inserted so that one end surface 5a comes into contact.

이와같이 이루어지는 종래의 보빈은, 상기 보빈(1)에 저압코일을 권선한 다음 그 외주면에 절연필름과 함께 고압코일을 권선하여 코일부(2)를 형성하고, 이 것을 플라이백 트랜스 케이스에 넣고 에폭시 수지 등으로 몰딩한 다음, 페라이트 코어(5)를 코어 삽입부(3)에 장착함으로써 플라이백 트랜스를 구성하고 있다.In the conventional bobbin thus obtained, a low pressure coil is wound around the bobbin 1 and a high pressure coil is wound along with an insulating film on the outer circumferential surface thereof to form a coil part 2, which is placed in a flyback trans case and an epoxy resin. After molding with the back and the like, the flyback transformer is constructed by attaching the ferrite core 5 to the core insertion section 3.

상기한 종래의 보빈 구조에 의하면, 에폭시 수지 몰딩시에 흘러넘친 수지(6)가 코어 삽입면(4)에 위치하여, 코어(5)의 삽입시 상기 넘친 수지(6)가 코어 일단면(5a)에 닿게 됨으로써, 페라이트 코어(5)가 바른 자세로 장착되기 어렵고, 이러한 경우 제품의 외형 불량은 물론 전기적 특성의 변화를 초래하게 된다.According to the above-described conventional bobbin structure, the resin 6 overflowed at the time of epoxy resin molding is located on the core insertion surface 4 so that the overflowed resin 6 at the time of insertion of the core 5 has the core end surface 5a. ), It is difficult for the ferrite core 5 to be mounted in a correct posture, and in this case, the appearance of the product is poor as well as a change in electrical characteristics.

본 고안은 이와같은 종래의 문제점을 해결하기 위하여, 일체형 보빈의 코어 삽입부에 넘친 수지를 수납하는 공간을 형성하고 또 코어 일단면에 닿아 코어를 바른 자세로 지지해주는 지지부를 상기 공간부에 형성함으로써, 에폭시 투입시 넘쳐흐른 수지로 인한 코어 장착 불량을 방지하고, 코어를 바른 자세로 장착할 수 있도록 한 몰딩수지의 넘침 수납구조를 가지는 일체형 보빈을 제공한다.In order to solve such a conventional problem, the present invention forms a space for accommodating the overflowed resin in the core insertion portion of the integral bobbin and forms a support portion in the space in contact with one end surface of the core to support the core in a correct posture. In order to prevent core mounting defects caused by overflowed resin when epoxy is added, and to provide the integrated bobbin having a overflowing storage structure of a molding resin for mounting the core in a correct posture.

도2는 본 고안의 일체형 보빈구조를 나타낸 일부 절개 사시도이고, 도3은 요부의 단면도로서;Figure 2 is a partially cutaway perspective view showing the integral bobbin structure of the present invention, Figure 3 is a cross-sectional view of the main portion;

일체형 보빈(1)으로서; 저압코일이 권선된 외주면에 절연필름과 함께 고압코일을 권선하여 코일부(2)가 이루어지고, 보빈의 상단에 페라이트 코어 삽입부(3)가 형성됨과 함께 몰딩시 넘쳐흐른 수지를 수납하는 수납공간부(4a) 및 이 공간부에서 페라이트 코어(5)를 지지하는 지지부(7,8)로서 단턱(7)과 돌기(8)를 형성한 구성이다.As integral bobbin 1; A coil part 2 is formed by winding a high pressure coil together with an insulating film on the outer circumferential surface of which the low pressure coil is wound, and a ferrite core insertion part 3 is formed at the upper end of the bobbin, and a storage space for storing resin overflowed during molding. It is the structure which the step 7 and the protrusion 8 were formed as the support part 7 and 8 which supports the ferrite core 5 in the part 4a and this space part.

이와같이 이루어지는 본 고안의 보빈은, 상기 보빈(1)에 저압코일을 권선한 다음 그 외주면에 절연필름과 함께 고압코일을 권선하여 코일부(2)를 형성하고, 이 것을 플라이백 트랜스 케이스에 넣고 에폭시 수지 등으로 몰딩한 다음, 페라이트 코어(5)를 코어 삽입부(3)에 장착함으로써 플라이백 트랜스를 구성하고 있다.The bobbin of the present invention made as described above, winding the low pressure coil on the bobbin 1 and then winding the high pressure coil with the insulating film on the outer circumferential surface thereof to form the coil portion 2, which is placed in a flyback trans case and epoxy After molding with resin or the like, the flyback transformer is constituted by attaching the ferrite core 5 to the core insertion section 3.

이와같이 에폭시 수지 몰딩시에 넘쳐흐른 수지(6)는 수납 공간부(4a)에 놓이게 된다.In this way, the overflowed resin 6 at the time of epoxy resin molding is placed in the storage space 4a.

그리고, 페라이트 코어(5)를 장착할때 그 일단면(5a)은 수납 공간부(4a)의 바닥에 닿지 않고 지지부(7,8)에 닿게 된다.When the ferrite core 5 is mounted, one end surface 5a of the ferrite core 5 touches the supports 7 and 8 without touching the bottom of the storage space 4a.

즉, 코어 일단면(5a)이 단턱(7)과 돌기부(8)에 닿게 되어 이곳에 지지되므로 코어는 넘쳐흐른 수지(6)의 간섭을 전혀 받지 않게된다.That is, since the core end surface 5a comes in contact with the step 7 and the protrusion 8 and is supported therein, the core is not subjected to interference of the overflowed resin 6 at all.

그러므로, 페라이트 코어(5)의 장착시에 페라이트 코어(5)는 넘쳐흐른 수지(6)에 관계없이 지지부(7,8)에 의해서 바른 자세로 보빈(1)의 코어 수납부(4a)에 장착된다.Therefore, when the ferrite core 5 is mounted, the ferrite core 5 is attached to the core housing 4a of the bobbin 1 in a correct posture by the support parts 7, 8 regardless of the overflowing resin 6. do.

상기한 바와같이 본 고안의 플라이백 트랜스 보빈 구조에 의하면, 에폭시 몰딩시에 넘쳐흐른 수지로 인한 페라이트 코어 장착 불량이 방지되고, 그러므로 페라이트 코어가 바른 자세로 장착되어 안정된 전기적 특성을 확보할 수 있게되며, 고품질의 플라이백 트랜스를 제작할 수 있게된다.As described above, according to the flyback trans bobbin structure of the present invention, the ferrite core mounting failure due to the overflowed resin during the epoxy molding is prevented, and thus the ferrite core is mounted in the correct posture to secure stable electrical characteristics. It will be possible to produce high quality flyback trance.
