본 고안은 접점판의 탄성변위에 의해서 접속이 이루어지게된 스위치에 있어서, 특히 접점판에 요환부를 형성시켜 제품의 진동에 의한 접점단속을 방지케 함으로써 제품의 안정성을 도모토록된 스위치의 접점단속 방지구조 관한 것이다.The present invention is a switch that is connected by the elastic displacement of the contact plate, in particular, by forming a concave part in the contact plate to prevent contact interruption caused by the vibration of the product prevents the contact interruption of the switch to ensure the stability of the product It is about structure.

종래에는 세탁기나 탈수기와 같이 제품자체의 진동이 큰 경우 접점판의 탄성력을 이용한 스위치를 사용하였는데, 즉 세탁기의 탈수조나 탈수기에 있어서 탈수뚜껑을 열고 탈수대상의 세탁물을 투입하고 탈수뚜껑을 닫은후 전원을 넣으면, 전원공급선을 통해서 전원이 모터로 인가되어 탈수통을 회전케 하면서 탈수행정을 진행케하는데, 이때 탈수뚜껑이 닫히면서 스위치동작부를 상방향으로 변위시키게 되면 하부접점판의 하부접점이 상부접점에 접지되면서 상부접점판을 통해 전원이 공급케 되었다.Conventionally, when the vibration of the product itself is large, such as a washing machine or a dehydrator, a switch using elastic force of a contact plate is used. If the power is supplied, the power is supplied to the motor through the power supply line to rotate the dehydration tank, and the dehydration stroke proceeds. At this time, if the dehydration lid is closed and the switch operation part is displaced upward, the lower contact point of the lower contact plate is the upper contact point. Power was supplied through the top contact plate as it was grounded at.

그런데, 탈수시 발생되는 진동이 상하부접점판에 전달되어, 접점의 단속이 순간적으로 반복되는 현상에 의한 불꽃이 발생되었고, 이로인한 접점의 발열로 안전상의 문제점을 야기하는 등에 결점을 내포하고 있었다.By the way, the vibration generated during dehydration was transmitted to the upper and lower contact plates, sparks were generated by a phenomenon in which the interruption of the contact points was instantaneously repeated, resulting in safety problems caused by heat generation of the contacts.

따라서 본 고안은 상기와 같은 결점을 해소시키기 위해서 하부접점판에 요환부를 형성시켜 발생된 진동을 흡수토록 하므로써 신뢰성있는 접속이 이루어지도록 하여 제품의 안전성은 물론 신뢰성 향상을 도모토록 안출된 것으로서 그 실시예를 첨부된 예시도면에 의거하여 구성 및 작용효과를 상세하게 설명하면 다음과 같다.Therefore, the present invention is designed to provide a reliable connection by absorbing the vibration generated by forming a concave part in the lower contact plate in order to solve the above-mentioned defects, and to improve the safety as well as the reliability of the product. When described in detail the configuration and the effect according to the accompanying drawings, as follows.

본 고안은 뚜껑(2)이 닫히면서 스위치동작부(4b)를 상방향으로 변위시켜 하부접점관(4)의 하부접점(4a)이 상부접점판(5)의 상부접점(5a)과 접지되면서 전원이 공급케된 스위치에 있어서, 하부접점판(4)를 끝단부로 스위치동작부(4b)및 일정위치로 하부접점(4a)을 설치하고 그 사이에 요환부(4c)를 형성시킨 하부접점판(4)과 일정위치로 상부접점(5a)이 설치된 상부접점판(5)을 고정부(3a)가 형성된 스위치본체(3)의 소정위치에 각각 매입시켜 구성시킨 것이다.According to the present invention, the lid 2 is closed and the switch operating portion 4b is displaced upward so that the lower contact 4a of the lower contact pipe 4 is grounded with the upper contact 5a of the upper contact plate 5. In a switch supplied with power, the lower contact plate having the lower contact plate 4 at its end and the switch contact portion 4b and the lower contact 4a at a predetermined position and the concave portion 4c formed therebetween. The upper contact plate 5 provided with the upper contact 5a at a predetermined position is embedded in (4) at a predetermined position of the switch body 3 on which the fixing part 3a is formed, respectively.

이와같이 구성된 본 고안의 작용효과를 상세하게 설명하면 다음과 같다. 세탁기의 탈수조나 탈수기의 탈수뚜껑을 열고 세탁대상의 세탁물을 투입하고 탈수뚜껑을 닫게되면 도면 제 3 도에 도시된 바와같이 뚜껑(2)이 반시계방향으로 회전하면서, 스위치본체(3)의 소정위치에 매입된 하부접점판(4)의 스위치동작부(4b)를 상방향으로 변위시키게 되고, 스위치동작부(4b)의 계속적변위로 하부접점판(4)의하부접점(4a)과 상부접점관(5)의 상부접점(5a)과의 최초접촉(θ3)이 이루어지게 되면서 전원공급선(6)를 통해 전원이 도면에 미도시된 모터로 공급되어 탈수통을 회전시키게 되고, 뚜껑(2)이 완전히 닫히게 되면서 하부접점판(4)은 이동각(θ2)으로 이루어지고 상부접점판(5)은 이동각(θ3)로 변위되게 되는데, 이때 하부접점판(4)의요환부(4C)에서는 탄성변형(θ)이 발생되어 상하부접점(5a) (4a)의 접점유지력으로 작용케됨과 동시에 뚜껑(2)의 진동에 의한 스위치동작부(4b)의 미세변위를 흡수토록한 것이다.Referring to the effect of the present invention configured in this way in detail as follows. When opening the dehydration tank of the washing machine or the dehydration cover of the dehydrator and putting the laundry to be washed and closing the dehydration cover, the lid 2 rotates counterclockwise as shown in FIG. The switch operating portion 4b of the lower contact plate 4 embedded in the position is displaced upward, and the lower contact 4a and the upper contact of the lower contact plate 4 are continuously displaced by the switch operating portion 4b. As the initial contact (θ 3 ) with the upper contact 5a of the pipe 5 is made, power is supplied to the motor not shown in the drawing through the power supply line 6 to rotate the dehydration container, and the lid 2 ) Is completely closed, the lower contact plate 4 is made of a moving angle θ 2 and the upper contact plate 5 is displaced at a moving angle θ 3 . ) Elastic deformation (θ) is generated and acts as the contact holding force of the upper and lower contact points (5a) (4a) One will ever absorb the fine displacement of the switch actuating part (4b) by vibration (2).

이상에서 설명한 바와같이 본 고안에 의하여 진동에 의한 미세변위를 탄성변형(θ)에서 홉수토록 함으로써, 접점단속에 의한 안전상의 문제점을 방지함은 물론 제품의 안전성 및 신뢰성을 한층더 향상시킬 수 있다는 등에 효과가 있는 것이다.As described above, the micro-displacement caused by vibration is hopped from the elastic deformation (θ), thereby preventing safety problems caused by contact interruption, and further improving the safety and reliability of the product. It works.
