본 고안은 가변저항기의 개량에 관한 것으로, 특히 저항체와 접촉되는 슬라이더를 로울러로 형성하여 저항판의 마모를 방지할 수 있도록한 것이다.The present invention relates to an improvement of the variable resistor, in particular, to form a slider in contact with the resistor to the roller to prevent the wear of the resistance plate.

종래의 일반적인 가변저항기는 손잡이를 회전시키면 손잡이 후단 회전체에 설치된 접속편이 저항판에 접촉된 상태로 회전하므로 장기간 사용시 접속편과 저항판의 마찰로 인해 저항판이 피막이 마모되어 정상적인 기능을 발휘할 수 없었고, 또 피막의 마모를 방지하기 위해 케이스에 윤활유를 주입하기 위한 주유공을 천공하였기 때문에 이 주유공으로 먼지다 기타 불순물등이 유입되어 저항체와 접속편의 접촉을 불량하게 하는 원인이 되었다.Conventional variable resistors, when the handle is rotated, the connecting piece installed on the rotating body of the rear end of the handle rotates in contact with the resistance plate. In addition, in order to prevent abrasion of the coating, the oil hole for lubricating oil was drilled into the case, so dust and other impurities were introduced into the oil hole, which caused a poor contact between the resistor and the connecting piece.

본 고안은 종래의 가변저항기가 지닌 이와 같은 결점을 해결하기 위해 저항판과 접속편의 접촉을 접촉 마찰식이 아닌 회전 접속식으로 하여 저항판의 마모를 최대한 억제하고 아울러 케이스를 완전 밀폐하여 먼지다 불순물의 유입을 방지토록한 것인바 이를 첨부 도면에 의해 그 구조를 더욱 상세히 설명하면 다음과 같다.In order to solve this drawback of the conventional variable resistor, the contact of the resistance plate and the connecting piece is a rotary connection rather than a contact friction type, which minimizes the wear of the resistance plate and completely seals the case. It will be to prevent the introduction of the structure by the accompanying drawings in more detail as follows.

케이스(1)내에 손잡이(3)와 연동하는 회전체(2)가 설치된 공지의 가변저항기에 있어서, 회전체(2)에 연결편(5)이 연설된 탄성재질의 접속판(4)을 부착하고 연결편(5)의 선단은 ""형으로 형성하여 그 양측 단부(5')(5'')에 톱니부(7)를 가진 로울러(6) 왓샤(8)(8')가 설치된 로울러 축(9)을 용착한다. 케이스(1)의 내주벽에는 로울러(6)의 톱니부(7)보다 약간 큰 치차간격을 가진 요철부(11)가 형성된 저항체(10)를 부착하여 로울러(6)의 톱니부(7)가 저항체(10)의 요철부(11)와 치합하여 회전가능하게 하여서 된 것이다.In the well-known variable resistor provided with the rotating body 2 which interlocks with the handle 3 in the case 1, the connection board 4 of the elastic material which the connection piece 5 was protruded was attached to the rotating body 2, The tip of the connecting piece 5 is " The roller shaft 9 formed with the roller 6 having the toothed portion 7 and the washer 8 and 8 'formed at both ends 5' and 5 " is welded. 1) is attached to the inner peripheral wall of the resistor (10) formed with the uneven portion 11 having a tooth gap slightly larger than the teeth (7) of the roller (6), the teeth 7 of the roller (6) is a resistor ( It is made to be rotatable by engaging with the uneven part 11 of 10).

이와 같이 구성된 본 고안은 접속판(4)과 연설되어 있는 연결편(5)의 선단에 설치된 로울러(6)의 톱니부(7)와 케이스(1) 내주벽에 부착된 저항체(10)의 요철부(11)가 치합되어 있어 손잡이(3)를 회전시키면 로울러(6)가 저항체(10)의 내주면을 따라 회동하면서 저항치를 변화시켜 주는 것으로, 로울러(6)가 탄성재질로 된 연결편(5)의 선단에 설치되어 있으므로 로울러(6)는 항상 연결편(5)의 탄발력에 의해 저항체(10)와 긴밀히 접촉된 상태로 회전하게 되고 저항체(10)에 형성된 요철부(11)와 로울러(6)에 형성된 톱니부(7)에 의해 회전작용이 더욱 원활하게 이루어 진다.The present invention configured as described above has uneven portions of the resistor 10 attached to the toothed portion 7 of the roller 6 and the inner peripheral wall of the case 1 installed at the tip of the connecting piece 5 which is connected to the connecting plate 4. When the handle 3 is rotated so that the roller 6 rotates along the inner circumferential surface of the resistor 10 to change the resistance value, the roller 6 is formed of an elastic material. Since the roller 6 is installed at the tip, the roller 6 always rotates in intimate contact with the resistor 10 by the elastic force of the connecting piece 5, and the uneven portion 11 and the roller 6 formed on the resistor 10 are rotated. Rotating action is made more smoothly by the formed tooth (7).

이와 같이 본 고안은 접촉 마찰식에 의해 저항체와 접속편을 접속시키던 종래의 가변저항기와는 달리 저항체(10)와 접속판(4)의 접촉을 구름마찰식에 의해 이루어지게 하므로서 저항체의 피막이 마모되는 것을 방지할 수 있고, 피막의 마모방지를 위한 윤활유의 주입이 필요없게 되므로 케이스(1)를 완전 밀폐시켜먼 지등의 유입을 방지할 수 있으므로 수명을 배가 시킬 수 있는 효과가 있다.As described above, the present invention, unlike the conventional variable resistor, which connects the resistor and the connecting piece by the contact friction type, makes contact between the resistor 10 and the connecting plate 4 by the frictional friction method, so that the coating of the resistor is worn. Since it is possible to prevent the injection of lubricating oil for preventing the wear of the coating, it is possible to completely seal the case (1) to prevent the inflow of dust, etc., thereby doubling the life.
