Description

전자렌지의 퓨즈 접속구조Fuse connection structure of microwave oven

본 고안은 전자렌지(microwave oven)에 관한 것으로서, 더 상세하게는 과전류의 인입을 방지하기 위한 퓨즈(fuse)를 접속시키는 구조에 관한 것이다.The present invention relates to a microwave oven, and more particularly to a structure for connecting a fuse (fuse) for preventing the introduction of overcurrent.

전자렌지는 음식물을 직접 가열하여 조리하는 가열조리방식과는 달리 조리실(cavity)의 트레이(tray)상에 조리할 음식물을 재치한 뒤, 마그네트론(magnetron)에서 발진된 고주파를 조리실에 조사(照射)함으로써 음식물의 분자공명(分子共鳴)에 의해 조리하는 장치이다.Unlike the heating cooking method in which the food is directly heated and cooked in the microwave, the food to be cooked is placed on a tray of the cavity, and the high frequency emitted from the magnetron is irradiated to the cooking chamber. This is an apparatus for cooking by molecular resonance of food.

이에 따라 전자렌지에는 마그네트론에 고전압을 인가하기 위한 고압(high voltage)의 트랜스(trance)와 캐패시터(capacitor)등 많은 전장품(電裝品)들이 구비되고, 이들에는 전원코드(power cord)를 통해 외부로부터 소정의 전원이 인가된다.Accordingly, the microwave oven is equipped with many electric appliances such as a high voltage transformer and a capacitor for applying a high voltage to the magnetron, and they are connected to the outside through a power cord. The predetermined power is applied from the

그런데 이와 같이 전자렌지에 전원을 인가하는 과정에서 전압변동 등의 외부요인이나 전장품의 쇼트(short)에 의해 과전류가 인입되게 되면, 특히 마그네트론 등의 전장품에 치명적인 손상을 입혀 고장을 유발할 뿐만 아니라 심한 경우 화재를 불러 일으킬 우려가 매우 많다. 이에 따라 일반적으로 외부로부터의 전원이 고압트랜스로 인가되는 경로, 예를들어 노이즈필터(noise filter)에 퓨즈를 구비하여 과전류의 인입시 퓨즈가 오픈되도록 함으로써 과전류에 의한 전장품의 손상를 방지하고 있다.However, in the process of applying power to the microwave, if an overcurrent is drawn in by external factors such as voltage fluctuations or shorts of the electronics, in particular, it causes fatal damage to the electronics such as magnetrons and causes failure as well as severe cases. There is a high risk of causing a fire. Accordingly, in general, by providing a fuse in a path through which power from an external source is applied to a high voltage transformer, for example, a noise filter, the fuse is opened when the overcurrent is drawn in, thereby preventing damage to the electrical component due to the overcurrent.

도 1에는 이와 같이 전원인가경로에 퓨즈를 접속시키는 종래의 구조를 도시하였다. 이것은 노이즈 필터(F)상에 대략 ㄷ자형 단면을 가지는 퓨즈홀더(fuse holder:1)를 스크류(screw:5)로 체결하고, 이 퓨즈홀더(1)의 양단부에 설치된 두 클립(clip:2)(3)에 퓨즈(4)의 두 터미널(4a)를 각각 탄성적으로 삽입시키고 있다. 또한 두 클립(2)(3)으로부터 외측방으로 연장된 두 탭터미널(tab terminal:2a)(3a)에 두 와이어(wire:6)(7)의 선단에 각각 구비된 커넥터(connecter:8)(9)들을 각각 접속시킴으로써 전원인가 경로에 퓨즈(4)를 접속시키고 있다.1 shows a conventional structure in which a fuse is connected to a power supply path as described above. It fastens a fuse holder 1 having a substantially U-shaped cross section on the noise filter F with a screw 5 and installs two clips 2 at both ends of the fuse holder 1. Two terminals 4a of the fuse 4 are respectively elastically inserted into (3). In addition, a connector 8 provided at each end of two wires 6 and 7 at two tab terminals 2a and 3a extending outwardly from the two clips 2 and 3, respectively. The fuses 4 are connected to the power supply path by connecting the 9 parts respectively.

그런데 이러한 종래의 퓨즈 접속구조는 두 와이어(6)(7)에 별도로 구성된 커넥터(8)(9)들을 각각 구비해야 할 뿐만 아니라 퓨즈홀더(1)의 탭터미널(2a)(3a)들에 커넥터(8)(9)를 꽂을때에도 퓨즈홀더(1)의 양쪽에서 각각 접속해야 하므로 부품수증가에 의한 원가상승은 물론 접속작업이 번잡한 문제가 있었다.By the way, such a conventional fuse connection structure has to be provided with the connectors 8 and 9 separately configured on the two wires 6 and 7 as well as the connectors on the tab terminals 2a and 3a of the fuse holder 1. (8) (9) also had to be connected from both sides of the fuse holder 1, respectively, so there was a problem that the connection work was complicated as well as the cost increase due to the increase in the number of parts.

본 고안의 목적은 상술한 종래의 문제를 감안하여 커넥터를 두 와이어에 각각 구비할 필요가 없으며, 한 번의 동작으로 퓨즈홀더의 두 탭터미널에 두 와이어의 커넥터를 동시에 간단하고 정확하게 접속시킬 수 있는 전자렌지의 퓨즈 접속구조를 제공하는 것이다.The object of the present invention is that it is not necessary to provide a connector on each of the two wires in view of the above-described conventional problems, and the electronics can easily and accurately connect the connectors of the two wires simultaneously to two tap terminals of the fuse holder in one operation. It is to provide a fuse connection structure of the stove.

이와 같은 목적을 달성하기 위해 본 고안에 의한 전자렌지의 퓨즈 접속구조는, 노이즈 필터상에 고정되는 퓨즈홀더와, 이 퓨즈홀더의 양단부에 각각 설치되어 퓨즈의 두 터미널을 각각 탄성적으로 삽입하는 두 클립과, 이 두 클립으로부터 연장되어 두 와이어와 각각 접속되는 두 탭터미널을 구비하는 전자렌지의 퓨즈 접속구조에 있어서, 두 탭터미널이 두 클립의 대향하는 내측단으로부터 각각 연장되며 퓨즈홀더의 한쪽 측면쪽으로 나란하게 돌출하도록 절곡 형성되고, 두 와이어가 두 탭터미널이 각각 삽입되는 두 접속구멍을 나란하게 가지는 하나의 커넥터에 함께 연결되는 것을 특징으로 한다.In order to achieve the above object, a fuse connection structure of a microwave oven according to the present invention includes two fuse holders fixed on a noise filter and two ends of the fuse holders respectively elastically inserting two terminals of the fuse. In a fuse connection structure of a microwave oven having a clip and two tap terminals extending from the two clips and connected to the two wires, respectively, wherein the two tap terminals extend from opposite inner ends of the two clips and are on one side of the fuse holder. It is bent to protrude side by side, characterized in that the two wires are connected together in one connector having two connection holes side by side each of which is inserted two tab terminals.

이에 따라 본 고안은, 한 번의 동작만으로 두 와이어를 퓨즈홀더의 두 탭터미널에 간단하고 확실하게 접속시킬 수 있게 되므로 전자렌지의 조립성 향상과 원가절감 등에 기여하게 된다.Accordingly, the present invention can easily and reliably connect the two wires to the two tap terminals of the fuse holder with a single operation, thereby contributing to the improvement of assembly of the microwave oven and the cost reduction.
