CONSTITUTION: A heater coil(100) of a high voltage transformer forms a square track shape to have a square hole at the center. The heater coil is formed by performing a pressing process with respect to a thin metal plate having a high conductivity. A wiring(102) of square track shape without connected portion is continuously formed at predetermined intervals while the metal plate forms a band shape because of the pressing process. The wiring is started at a side of the hole(103) and wound three or four times along the shape of the hole(103). By the pressing process, only the wiring(102) is left. The wiring(102) maintains a predetermined interval from an inside end part(104) where it is started to an outside end part(105) where it is terminated. The wiring has a similar shape to the hole(103) and wound three or four times.

The receptacle 106 is directly installed on the outer end 105, and the inner end 104 extends long to cross the other terminals, and then the receptacle 106 is installed at the end thereof. Thus, by installing the insulating tube 108 in the intersection, it can be insulated.

또한 도 7 도시와 같이 내측단부(104)와 외측단부(105)에 직접 단자(107)를설치하게 되는데, 이 경우 역시 리셉터클(106)의 설치와 같이 각 단부(104)(105)가 서로의 간섭을 고려하여 일정한 거리를 두고 위치하게 된다.In addition, as shown in FIG. 7, the terminal 107 is directly installed at the inner end 104 and the outer end 105, in which case each end 104, 105 is connected to each other, such as the installation of the receptacle 106. It is located at a certain distance in consideration of the interference.

이렇게 구성되는 본 발명은 중앙홀(103)을 구비하는 사각트랙형상의 금속판을 프레싱 가공하여 띠형상을 이루면서 연결부위가 없는 사각 트랙 모양의 배선(102)만이 소정간격으로 연속 형성되게 하는 한편, 내측단부(104) 및 외측단부(105) 각각에 리셉터클(106) 또는 단자(107)를 결합하여서 되는 것이다. 따라서 와인딩공정 없이 히터코일을 성형하게 됨으로써, 생산 원가 및 생산성을 향상시킬 수 있고 또한 단자에 의한 결선 작업으로 작업성을 향상시킬 수 도 있는 것이다.According to the present invention configured as described above, the rectangular track-shaped metal plate having the central hole 103 is pressed to form a strip shape, and only the rectangular track-shaped wiring 102 having no connection portion is continuously formed at predetermined intervals, The receptacle 106 or the terminal 107 is coupled to each of the end 104 and the outer end 105. Therefore, by forming the heater coil without the winding process, it is possible to improve the production cost and productivity, and also to improve the workability by the connection work by the terminal.
