3 : 고무튜우브 4,7 : 절연와서3: rubber tube 4,7: with insulation

본 고안은 로타리 스위치의 회전축 절연장치에 관한 것으로서 금속제로 형성된 회전축의 걸림턱 전후에 절연성을 갖는 고무튜우브를 끼우고 금속제로 형성된 이동단자와 판스프링의 외측면으로 난연성 합성수지제로 형성된 절연와셔를 게재하여 이동단자와 판스프링을 너트로 조립 고정 하였으므로 로타리 스위치를 사용중에 고무튜우브와 절연와셔에 의하여 회전축으로 전류가 절연되어 불의의 인명사고를 미연에 방지 할 수 있게 되고 회전축과 전원 접속단자와의 전기적 절연으로 인하여 전류의 누설을 방지 할 수 있으며 전압 조정단자와 전원 접속단자를 서로 연결하는 전선의 나선 부분이 회전축에 닿을 경우에도 회전축에 전류가 통전되지 아니하므로 전류가 누설 될 우려가 전혀 없고 안전하게 사용 할 수 있도록 한 것이다.The present invention relates to a rotary shaft insulator of a rotary switch, inserting an insulating rubber tube before and after the locking jaw of the rotary shaft made of metal, and a mobile terminal made of metal and an insulating washer made of flame-retardant synthetic resin on the outer surface of the leaf spring. Since the moving terminal and the leaf spring are assembled and fixed with nuts, the current is insulated from the rotary shaft by the rubber tubing and the insulating washer while the rotary switch is used to prevent accidental accidents and to prevent electrical accidents between the rotary shaft and the power connection terminal. Insulation prevents leakage of current, and even if the spiral part of the wire connecting the voltage adjusting terminal and the power connection terminal touches the rotating shaft, current does not flow through the rotating shaft, so there is no risk of leakage of current. It is to be done.

종래에 사용되어 오고 있는 로타리 스위치는 금속제의 회전축에 금속제로 형성된 이동단자와 판스프링을 너트로 조립하고 전압 조정단자가 다수 배설된 합성수지제로 형성된 기판에 조립하였으므로 회전축과 이동단자 사이에 절연이 되지 않는 구성이어서 로타리 스위치를 사용중에 회전축으로 전류가 통전 되어 불의의 인명사고가 발생될 우려가 있었고 전압 조정단자와 전원 접속단자를 서로 연결하는 전선의 나선부분이 회전축에 닿을 경우에는 열 발생에 따른 화재의 위험성을 일으키게 될 우려가 있었고 전류가 누설되는 등의 문제점이 있었다.The rotary switch, which has been used in the past, is assembled with a metal plate on a rotating shaft made of metal and a plate spring by a nut, and assembled on a board formed of synthetic resin with a large number of voltage adjusting terminals, so that there is no insulation between the rotating shaft and the mobile terminal. Due to the configuration, electric current is supplied to the rotating shaft while the rotary switch is in use, which may cause an accidental accident.If the spiral part of the wire connecting the voltage adjusting terminal and the power connection terminal touches the rotating shaft, There was a risk of causing a risk and there was a problem such as leakage of current.

본 고안은 이와 같은 종래 로타리 스위치의 전기적 문제점을 시정 보완하여 보다 안전하게 사용할 수 있는 로타리 스위치를 제공하고저 고안된 것으로서 이하 본 고안을 첨부된 도면에 의하여 그 구조를 상세히 설명하면 다음과 같다.The present invention is to provide a rotary switch that can be used more safely by correcting the electrical problems of the conventional rotary switch as described below in detail the structure of the present invention by the accompanying drawings as follows.

회전축(1)의 걸림턱(2) 내측으로 이동단자(5)와 판스프링(6)을 너트(8)로 고정 하여서된 통상의 로타리 스위치의 회전축(1)에 있어서, 걸림턱(2)의 전후로 절연성을 갖는 고무튜우브(3)를 끼우고 이동단자(5)와 판스프링(6)의 외측면으로 절연와셔(4)(7)를 게재하여 구성된 것을 특징으로 하는 것이다.In the rotary shaft 1 of the conventional rotary switch, which is fixed by the nut 8 with the movable terminal 5 and the leaf spring 6 inside the locking step 2 of the rotating shaft 1, It is characterized in that it is configured by inserting the rubber tubing 3 having insulation before and after the insulation washer (4) (7) on the outer surface of the mobile terminal (5) and the leaf spring (6).

이와 같이 구성된 본 고안의 작용 효과를 상세히 설명하면, 금속제로 형성된 회전축(1)의 걸림턱(2) 내측으로 금속제로 형성된 이동단자(5)와 판스프링(6)을 끼워 너트(8)로 고정하고 회전축(1)의 회전으로 그 일단부에 형성된 접점부가 전압 조정단자(도면에 도시하지 않았음)의 절점과 접속되어 전압을 조정하는 것은 공지하나. 이와 같은 종래의 구성은 전기적으로 절연이 되지 않아 회전축에 전류가 통전 되므로 인하여 불의의 인명사고를 당할 우려가 있었고 전류의 누설로 인하여 화재의 위험성이 있는 문제점이 있게 되었던 바, 본 고안은 회전축(1)의 걸림턱(2) 전후로 절연성을 갖는 고무튜우브(3)를 끼우고 이동단자(5)와 판스프링(6)의 외측면으로 절연성을 갖는 난연성 합성수지제로 형성된 절연와셔(4)(7)를 게재하여(걸림턱(2) 내측으로 절연와셔(4), 이동단자(5), 판스프링(6), 절연와셔(7)를 순서대로 조립) 너트(8)로 조립 구성하였으므로 기판에 배설된 전원고정단자와 접속되는 이동단자(5) 및 판스프링(6)에 통전되는 전류가 고무튜우브(3)와 절연와셔(4)(7)에 의하여 회전축(1)에 통전되지 아니하고 또한 전원 고정단자와 전원 접속단자를 연결하는 전선의 나선 부분이 회전축(1)에 닿을 경우가 있다 하더라도 고무튜우브(3)와 절연와서(4)(7)에 의하여 회전축(1)에 전류가 통전되지 아니하므로 불의의 인명사고를 미연에 방지 할 수 있으며 또한 전선의 나선부분이 회전축(1)에 닿을 경우에도 열 발생을 일으킬 우려가 없어 화재의 위험성이 없고 전류의 누설이 발생하지 않아 안전하게 사용할 수 있는 등의 작용 효과를 나타내는 것이다.When explaining the operation and effect of the present invention configured in this way in detail, the mobile terminal 5 and the leaf spring (6) formed of the metal is inserted into the locking jaw (2) of the rotating shaft (1) made of metal and fixed with the nut (8) The contact portion formed at one end thereof by the rotation of the rotating shaft 1 is connected to the node of the voltage adjusting terminal (not shown) to adjust the voltage. Such a conventional configuration is not electrically insulated so that a current may be supplied to the rotating shaft, thereby causing an accidental human accident and a risk of fire due to leakage of current. Insulation washer (4) and (7) formed of a flame-retardant synthetic resin having an insulating rubber tube (3) before and after the locking step (2) of the crankshaft (2) and insulating the outer surface of the mobile terminal (5) and the leaf spring (6). (The assembly of the insulating washer 4, the movable terminal 5, the leaf spring 6, and the insulating washer 7 in order) is placed on the inside of the catching jaw 2, and the nut 8 is assembled. The electric current flowing through the mobile terminal 5 and the leaf spring 6 connected to the fixed power supply fixed terminal is not energized by the rubber tube 3 and the insulating washer 4 and 7 to the rotating shaft 1 and Spiral part of electric wire connecting fixed terminal and power connection terminal 1) Even if it touches the current, the current is not energized by the rubber tube 3 and the insulation washer 4, 7 so that an accidental accident can be prevented. Even if the spiral part contacts the rotating shaft 1, there is no risk of generating heat, and thus there is no risk of fire and leakage of current does not occur.
