It relates to a microwave oven for.

일반적으로, 전자렌지는 상용교류전원으로부터 교류전압을 인가받아 고압으로 변환하여 마그네트론을 구동시킴에 의해, 그 마그네트론으로부터 발생되는 고주파수의 마이크로파를 조리물에 가하여 조리물 물분자의 진동에 의해 발생되는 고열로 조리가 진행되도록 되어 있다.In general, microwaves are supplied with AC voltage from a commercial AC power source and converted to high voltage to drive a magnetron. By applying microwaves of high frequency generated from the magnetron to the food, high heat generated by vibration of the water molecules of the food. Cooking is to proceed.

이러한 교류용 전자렌지는 마그네트론 및 그 마그네트론의 구동에 필요한 각종 전장품이 장착되어 있는 장치실과, 조리물을 안착하고서 마그네트론으로부터 발생되는 마이크로파를 도파관을 통해 도입받아 조리가 진행되는 조리실로 구획되어 있다.The microwave oven is divided into a device chamber equipped with a magnetron and various electrical appliances required for driving the magnetron, and a cooking chamber in which microwaves generated from the magnetron are introduced through the waveguide while the food is settled through the waveguide.

그러한 장치실내에는 마그네트론의 구동을 위한 각종 전장품을 안착하고, 교류전원을 인가받아 회로동작을 수행하기 위한 피씨비 기판이 장착되는 바, 그러한 피씨비 기판에 전원도선 등과 같은 외부로부터의 접속부재를 접속하기 위한 접속구조는 도 1 및 도 2에 도시된 바와 같다.In such a device room, a variety of electronic devices for driving the magnetron are mounted, and a PCB board is mounted to perform a circuit operation by receiving an AC power supply, and the PCB board is connected to an external connection member such as a power supply wire. The connection structure is as shown in Figs.

즉, 도 1은 종래의 일예에 따른 전자랜지내의 회로기판에 대한 접속구조를 나타낸 단면도이다.1 is a cross-sectional view showing a connection structure to a circuit board in a microwave oven according to a conventional example.

도 1에 도시된 바와 같이, 종래의 일예에 따른 회로기판 접속구조에서는, 피씨비 기판(2)의 상/하면에 걸쳐서 도전성의 동박판(4)이 도포된 부위에 나사공을 통해서 도전성의 체결나사(6)가 체결된다. 상기 체결나사(6)의 나사부에는 제 1너트(8A)가 삽입된 다음에, 전원도선(7)의 나선부분이 감기게 되고, 상기 전원도선(7)의 나선부분을 고정시키기 위한 제 2너트(8B)가 최종적으로 체결된다.As shown in FIG. 1, in a circuit board connection structure according to a conventional example, a conductive fastening screw is formed through a screw hole to a portion where a conductive copper plate 4 is coated over an upper and a lower surface of a PCB substrate 2. (6) is fastened. After the first nut 8A is inserted into the screw portion of the fastening screw 6, the spiral portion of the power lead 7 is wound, and the second nut for fixing the spiral portion of the power lead 7 8B is finally fastened.

또한, 도 2는 종래의 다른 예에 따른 회로기판 접속구조를 나타낸 단면도이다.2 is a cross-sectional view showing a circuit board connection structure according to another conventional example.

도 2에 도시된 바와 같이, 종래의 다른 예에 따른 회로기판 접속구조에서는, 회로기판(2)의 도전성 동박판(4)이 도포된 부위에 체결나사(6)가 체결된 다음에, 그 체결나사(6)의 나사부에 제 1너트(8A)가 삽입되고, 전원도선(7)의 나선부분이 감긴 다음에, 제 2너트(8B)가 고정된다.As shown in FIG. 2, in the circuit board connection structure according to another conventional example, after the fastening screw 6 is fastened to a portion where the conductive copper foil 4 of the circuit board 2 is coated, the fastening screw 6 is fastened. The first nut 8A is inserted into the threaded portion of the screw 6, the spiral portion of the power supply wire 7 is wound, and then the second nut 8B is fixed.

한편, 여기서는 상기 제 1너트(8A)와 피씨비 기판(2)의 사이에 와셔(10)를 추가하여 체결나사(6)와 볼트(8)의 체결도를 향상시키도록 하고 있다.On the other hand, here, a washer 10 is added between the first nut 8A and the PCB 2 to improve the fastening degree of the fastening screw 6 and the bolt 8.

그러나, 이러한 종래의 회로기판 접속구조는 교류용 전자렌지의 전원도선 등과 같은 접속부재를 접속하기 위한 용도로서 개발되어 있기 때문에, 직류전원의 고전류 특성에 따라 전원도선의 두께가 약 22㎟ 정도까지 두꺼워질 수 밖에 없는 직류용 전자렌지에 적용되는 경우에는 그 전원도선의 증가된 두께에 의해 체결토크가 낮아지게 되므로 도선의 나선과 피씨비 기판간의 접촉성이 떨어지게 되어 전기 전도도가 저하된다는 문제점을 갖게 된다.However, such a conventional circuit board connection structure has been developed for connecting a connection member such as a power supply lead of an AC microwave oven, so that the thickness of the power supply lead is thick to about 22 mm2 depending on the high current characteristics of the DC power supply. When applied to a direct-current microwave oven that can not help but lose the fastening torque due to the increased thickness of the power supply wire has a problem that the electrical conductivity is lowered because the contact between the wire and the PCB of the wire is lowered.

또한, 상기한 종래의 접속구조에서는 체결나사에 삽입되는 너트가 피씨비 기판의 동박판에 직접 접촉되도록 되어 있기 때문에, 보다 밀접한 체결성을 위해서 너트를 무리하게 잠금작용하게 되면 동박판이 손상된다는 문제점이 있다.In addition, in the conventional connection structure described above, since the nut inserted into the fastening screw is in direct contact with the copper plate of the PCB, the copper plate is damaged when the nut is forcibly locked for tighter fastening. have.

따라서, 그러한 직류용 전자렌지의 고전류용 피씨비 기판에 상당히 두꺼운 두께를 갖는 전원 도선 등의 접속부재를 접속하기 위해 종래의 접속구조를 적용하기에는 적합하지 않게 된다.Therefore, it is not suitable for applying a conventional connection structure to connect a connection member such as a power supply lead having a considerably thick thickness to such a high current PC board of a direct current microwave oven.

본 발명은 상기한 종래의 사정을 감안하여 이루어진 것으로서, 그 목적은 전자렌지의 회로기판에서 고전류용 전원도선 등의 접속부재가 접속되는 부위에 도전성의 보강패널을 개재시킴에 의해, 체결토크를 향상시켜서 접속불량으로 인한 전기 전도도의 저하가 방지될 수 있도록 하기 위한 전자렌지를 제공하는 것이다.SUMMARY OF THE INVENTION The present invention has been made in view of the above conventional circumstances, and an object thereof is to improve fastening torque by interposing a conductive reinforcement panel at a portion where a connection member such as a high current power supply lead is connected to a circuit board of a microwave oven.
