본 고안은 일반가정에서 사용되는 전자렌지용 고전압트랜스에 관련된 것으로서, 이는 특히 고압보빈에 단자핀이 삽입되는 삽입부의 내면하단상측에 삼각돌기부를 돌설하여 단자핀을 보다 견고하게 고정할 수 있도록한 전자렌지용 고전압트랜스의 단자핀 결합구조에 관한 것이다.The present invention relates to a high-voltage transformer for microwave ovens used in general homes, which in particular, has a triangular protrusion on the upper inner bottom side of the insert portion into which the terminal pin is inserted into the high-pressure bobbin, so that the terminal pin can be more firmly fixed. It relates to a terminal pin coupling structure of a high voltage transformer for a range.

일반적인 전자렌지용 고전압트랜스에 있어서는, 제 1 도 및 제 2 도에서 도시한 바와같이 고압보빈(1)의 외주면측으로 돌출되어 형성된 단자핀 삽입홀(10) 및 기립편삽입구(11)를 형성하며, 이에 대응하는 단자핀(2)의 일측단부와 그 상측으로 절곡기립된 절곡기립편(20)을 결합하는 구성으로 되어 있다.In the general microwave high voltage transformer, as shown in FIGS. 1 and 2, the terminal pin insertion hole 10 and the standing piece insertion hole 11 protruding toward the outer circumferential surface side of the high-pressure bobbin 1 are formed. One side end portion of the corresponding terminal pin 2 and a bending erecting piece 20 bent upright are formed.

그러나, 고압보빈(1)의 단자핀삽입홈(1)에 단자핀(2)을 장착하려면 사출물의 특성인 수축현상으로 치수차이가 너무 심하여 상호조립하기가 매우 어려운 것이었고, 이로인하여 작업능률이 저하될 뿐만 아니라 고가로 제작된 고압보빈(1)을 사용할 수 없는 것이어서 자재손실이 되는등의 큰 문제점이 있었다.However, in order to mount the terminal pin 2 to the terminal pin insertion groove 1 of the high-pressure bobbin 1, it is very difficult to assemble them because the dimensional difference is too great due to the shrinkage phenomenon, which is the characteristic of the injection molding. Not only was it not possible to use the high-pressure bobbin (1) made expensive, there was a big problem such as material loss.

또, 사출물로 고압보빈(1)을 만들기 위해 금형제작시, 코어(Core)의 강도가 약해 양산성이 전혀 없어서 향후 문제점이 발생되면 당장 그 적용을 하지 못하므로 인해 양산에 큰차질이 생기는 등의 문제점도 있었다.In addition, when the mold is manufactured to make the high-pressure bobbin (1) from the injection molded product, the strength of the core is weak and there is no mass production. Therefore, if a problem arises in the future, it cannot be applied immediately. There was a problem.

본 고안은 이러한 종래의 문제점을 해결하기 위하여 안출한 것으로서 이는 특히 고압보빈의 단자핀삽입부하단에 돌턱 및 삼각 돌기부를 형성하여 금형상으로 강도를 보강함과 아울러 단자핀이 삼각돌기부의 상단을 깍아먹으면서 삽입되게끔하여 보다 견고하게 조립할 수 있어 조립성을 양호하게 하는데 그 목적이 있는 것이다.The present invention has been devised to solve such a conventional problem, and in particular, a stepped and triangular protrusion is formed at the lower end of the terminal pin insertion portion of the high-pressure bobbin to reinforce the strength in a mold, and the terminal pin cuts the upper end of the triangular protrusion. It is intended to be inserted while eating so that you can assemble more firmly, the assembly is good.

이하 도면에 따라 더욱 상세히 설명하면 다음과 같다.When described in more detail according to the drawings as follows.

즉, 본 고안은 제 3 도 및 제 4 도에 도시한 바와 같이 고압보빈(1)의 외주면측으로 돌출되어 형성된 단자핀삽입홀(10) 및 기립편삽입구(11)에 대응하는 단자핀(2)과 그 상측으로 절곡기립된 기립편(20)을 결합구성하는 것에 있어서, 상기 고압보빈(1)의 단자핀삽입홀(10)의 내면하단상측으로 복수의 삼각돌기부(3)를 돌설하며, 그 내면으로 삼각돌기부(3) 상단과 동일한 돌턱(4)을 형성한 구성으로 된다.That is, according to the present invention, as shown in FIGS. 3 and 4, the terminal pin insertion hole 10 and the terminal pin 2 corresponding to the standing piece insertion opening 11 protruding toward the outer circumferential surface side of the high-pressure bobbin 1 are formed. And in the coupling configuration of the upstanding piece 20 bent upwards, a plurality of triangular projection (3) protruding toward the upper inner bottom end side of the terminal pin insertion hole 10 of the high-pressure bobbin (1), Inner surface of the triangular projection (3) is formed with the same projection (4).

상기 삼각돌기부(3)의 입구측은 모따기면(30)을 형성하여 단자핀(2)의 삽입을 용이하게 하였으며 삼각돌기부(3)의 입구측에서 일정각도로 내측단부까지 올라가도록 경사지게 경사면(31)이 형성되는 구성으로 된다.The inlet side of the triangular protrusion 3 has a chamfered surface 30 to facilitate the insertion of the terminal pin 2, the inclined surface 31 inclined so as to rise from the inlet side of the triangular protrusion 3 to the inner end at a predetermined angle. This configuration is formed.

이와같이 구성된 본 고압은 고압보빈(1)의 단자핀삽입홀(10)에 형성된 삼각돌기부(3)의 모따기면(30)으로 단자핀(2)의 일측 단부를 삽입하면, 상기 모따기면(30)에 의해 단자핀(2)이 용이하게 삽입되며, 상기 단자핀(2)의 하단으로 상기 삼각돌기부(3) 상단의 경사면(31) 일부를 깍아먹으면서 들어가게 되어 고압보빈(1)과 단자핀(2)이 완전히 조립된 후에는 삼각돌기부(3)의 상측으로 형성된 경사면(31)에 의해 억지끼워맞춤형식으로 보다 견고하게 조립되는 것이다.When the high pressure configured as described above inserts one end of the terminal pin 2 into the chamfer surface 30 of the triangular protrusion 3 formed in the terminal pin insertion hole 10 of the high pressure bobbin 1, the chamfer surface 30 is formed. By the terminal pin (2) is easily inserted, the high pressure bobbin (1) and the terminal pin (2) to enter the lower portion of the terminal pin (2) while scraping a portion of the inclined surface 31 of the top of the triangular projection (3) ) Is completely assembled, and then firmly assembled in an interference fit type by the inclined surface 31 formed on the upper side of the triangular protrusion 3.

또, 상기 삼각돌기부(3)의 내측으로 돌설된 돌턱(4)으로 고압보빈(1)을 만들기 위하여 금형제작시에 코어의 강도가 약한 것을 해결할 수 있으므로 인해 양산성이 가능한 것이다.In addition, since the strength of the core at the time of mold production can be solved in order to make the high pressure bobbin 1 with the protrusion 4 protruded into the inside of the triangular protrusion 3, mass production is possible.

이와같이 된 본 고안은 고압보빈(1)의 단자핀삽입부(10)에 삼각돌기부(3) 및 돌턱(4)을 형성하므로서 단자핀(2)을 용이하게 고압보빈(1)에 삽입고정하고, 금형상으로도 코오가 삽입되는 부분의 강도를 보강할 수 있는 유익한 특징이 있는 고안이다.The present invention as described above forms a triangular protrusion (3) and the projection (4) in the terminal pin insertion portion 10 of the high pressure bobbin (1) to easily insert and fix the terminal pin (2) to the high pressure bobbin (1), It is an invention with advantageous features that can reinforce the strength of the part where the ko is inserted into the mold.
