본 고안은 용접기용 전자접촉기에 관한 것으로, 특히 고압 전류를 이용하는 용접기에 사용하여 전격을 방지하기 위한 용접기용 전자접촉기에 관한 것이다.The present invention relates to a magnetic contactor for a welder, and more particularly, to a magnetic contactor for a welder for preventing electric shock by using a welder using a high voltage current.
종래 용접기에 있어서는 특고압의 용접전원이 부하측에 연결되고 용접전원을 공급하는 전원라인의 하나, 예를 들어 +측 전원라인에 기계적인 스위치가 결합되는 구조로 되어 있다. 그러나 이러한 용접기에 있어서는 작업자가 스위치를 조작하면서 용접작업을 하게되는데 이러한 스위치가 폐쇄된 상태에서 용접기구를 방치하는 경우 부주의로 작업자 또는 작업장소에 근접한 사람이 심각한 전기 충격을 받을 우려가 있다.In the conventional welding machine, a high voltage welding power source is connected to a load side, and a mechanical switch is coupled to one of power lines for supplying welding power, for example, a + side power line. However, in such a welding machine, a worker performs welding while operating a switch. When the welding apparatus is left in a state in which the switch is closed, a worker or a person close to the work place may inadvertently receive a serious electric shock.
본 고안에 있어서는 종래의 이와 같은 점을 감안하여 안출한 것으로, 전원라인에 연결하여 용접기를 사용할 때에만 전자(電磁)적으로 작용하여 전원라인을 연결할 수있도록하여 작업자를 전격으로부터 보호할 수 있도록 한 것인바, 이를 첨부도면에 의거하여 보다 상세히 설명하면 다음과 같다.In the present invention, in view of the above-mentioned point in the prior art, it is designed to protect the operator from electric shock by connecting to the power line and acting only electronically when the welding machine is used to connect the power line. It will be described in more detail based on the accompanying drawings as follows.
상부갑체(1)와 하부갑체(2)로 구성되고 하부갑체(2)내에 코일(3)이 결합된 고정칠심(4)을 내장하고 상부갑체(1)의 상부에는 접점돌기(5)를 갖는 수평부(6)와 전원라인(도시하지 않았음)이 기계적으로 연결되는 수직부(7)를 갖는 "ㄴ"자형 고정접점(8)(8')을 간격을 두고 착설한 것에 있어서, 상부갑체(1)의 상부중앙에 기다란 통공(9)을 형성하여 고정칠심(4)의 상부측에 가동철심(10)이 착설된 가동철심갑체(12)를 배치하고 이 가동철심갑체(12)의 양측에 스프링지지대(13)(13')를 일체로 형성하여 하부갑체(2)의 저면일부와의 사이에 압축 스프링(14)(14')을 개재하며, 가동철심갑체(12)의 상부에는 상부갑체(1)의 기다란 통공(9)을 통하여 상부로 연장되는 판상지지대(15)를 일체로 형성하고 이 판상지지대(15)에는 사각통공(16)을 형성하여 저면측에 판상의 가동접점(17)을 착설하고 이 가동접점(15)과 사각통공(16)의 상면 사이에 압축스프링(18)을 착설하여 가동접점(17)을 하향탄지하며, 상부갑체(1)의 양측에 판상지지대(15)를 안내지지하는 측벽(19)(19')을 상향연장하여 상부에 중앙통공(20)을 갖는 커어버판(21)의 통공(20)에 삽입되어 상향돌출되게 하여서된 구조이다.It is composed of the upper body (1) and the lower body (2) and has a fixed chisel (4) in which the coil 3 is coupled in the lower body (2) and has a contact protrusion (5) on the upper body (1) In the case where the “b” shaped fixed contacts 8 and 8 ′ are installed at intervals with the vertical part 7 where the horizontal part 6 and the power line (not shown) are mechanically connected, the upper body An elongated through hole 9 is formed in the upper center of (1) to arrange the movable iron core body 12 on which the movable iron core 10 is installed on the upper side of the fixed core 4 and both sides of the movable iron core body 12. Spring supports 13, 13 'are integrally formed in the interposed portion, and compression springs 14, 14' are interposed between the lower portion of the lower body 2 and the upper portion of the movable iron core body 12. A plate-shaped support 15 extending upwardly through the elongated through hole 9 of the upper body 1 is integrally formed, and the plate-shaped support 15 is formed with a rectangular through hole 16 to form a plate-shaped movable contact 17 on the bottom side. ) And a compression spring 18 is installed between the movable contact 15 and the upper surface of the rectangular hole 16 to carry out downward support of the movable contact 17, and the plate support 15 is provided on both sides of the upper body 1. The guide supporting side walls 19 and 19 'are upwardly extended to be inserted into the through holes 20 of the cover plate 21 having the central through holes 20 at the top thereof to protrude upward.
이와 같은 본고안은 하부갑체(2)에 코일(3)이 결합된 고정철심(4)에 대하여 가동철심(10)이 착설된 가동철심갑체(12)가 이 가동철심갑체(12)의 스프링지지대(13)(13')와 하부갑체(2) 사이에 착설된 압축스프링(14)(14')에 의하여 상향탄지된 상태가 유지된다. 따라서 평상시에, 즉 용접기를 사용치 않는 경우에는 가동철심(10)이 착설된 가동철심갑체(12)가 상향탄지되어 가동철심갑체(12)의 상부로 연장된 판상지지대(15)의 사각통공(16)에서 그 저면측에 압축스프링(18)으로 하향탄지된 가동접점(17)은 상부갑체(1)의 상부에 착설된 고정접점(8)(8')으로부터 상측방향으로 떨어져 있는 상태가 유지된다(제3도 참조). 이러한 상태에서는 고정접점(8)(8')의 수직부(7)에 연결된 전원라인이 연결되지 않아 용접기에 고압전류가 흐르는 것이 차단되어 전격을 방지할 수 있다. 용접기를 사용하고자 할때에는 고정철심(4)에 결합된 코일(3)에 전류를 인가한다. 이 코일(3)에 인가되는 전류는 용접기작업을 지시감독할 수 있는 위치에서 공급된다. 이 코일(3)에 전류가 인가되면 고정철심(4)이 자화되어 스프링(14)(14')의 탄력에 반하여 가동철심(10)을 당기게되므로 이 가동철심(10)과 함께 가동철심갑체(12)가 하향 이동된다. 이러한 가동철심갑체(12)의 하향 이동으로 이에 일체로 구성된 판상지지대(15)가 하향되면서 이에 착설된 가둥접점(17)이 고정접점(8)(8')에 접촉하여 이들 고정접점(8)(8')에 연결된 용접기의 전원라인을 전기적으로 연결하게 되어 용접기에 용접전류가 흐르도록 한다.In this proposal, the movable iron core body 12 on which the movable iron core 10 is installed with respect to the fixed iron core 4 to which the coil 3 is coupled to the lower body 2 is a spring support of the movable iron core body 12. (13) (13 ') and the state uplifted by the compression spring (14, 14') installed between the lower body 2 is maintained. Therefore, in normal times, that is, when the welding machine is not used, the rectangular core hole of the plate support 15 extending upwardly from the movable core core 12 on which the movable core 10 is installed is extended to the upper portion of the movable core core 12 ( 16, the movable contact 17 held downward by the compression spring 18 on the bottom side thereof is kept in an upward direction away from the fixed contact 8, 8 'installed on the upper part of the upper body 1. (See Figure 3). In this state, the power line connected to the vertical portion 7 of the fixed contact 8 and 8 ′ is not connected to prevent the high voltage current from flowing to the welder, thereby preventing electric shock. When using a welding machine, a current is applied to the coil 3 coupled to the fixed core 4. The current applied to this coil 3 is supplied at a position capable of directing and supervising the welder operation. When a current is applied to the coil 3, the fixed core 4 is magnetized to pull the movable core 10 against the elasticity of the springs 14 and 14 ′, and thus the movable core core together with the movable core 10 ( 12) is moved downward. As the movable support core 12 moves downward, the plate support 15 integrally formed thereon moves downward, and the floating contact 17 installed on the movable contact core 12 contacts the fixed contacts 8, 8 ′. The electric power line of the welding machine connected to (8 ') is electrically connected so that the welding current flows to the welding machine.
이때에 판상지지대(15)의 상부에 형성된 돌기(22)가 커어버판(21)의 통공(20)을 통하여 평상시에는 상향 돌출되어 있던 상태에서 통공(20) 내측으로 하향이동하므로 감독자는 이를 보고 현재 용접전류가 흐르고 있음을 확인할 수 있다. 또한 가동접점(17)은 판상지지대(15)의 사각통공(16) 하측에 스프링(18)으로 하향탄지되어 있어 이 스프링(18)에 의하여 가동접점(17)이 고정접점(8)(8')에 접점된 상태를 유지한다.At this time, the projection 22 formed on the upper plate support 15 is moved through the through hole 20 of the cover plate (21) in a state that normally protrudes upward in the state of the through hole 20 so the supervisor sees this It can be seen that the welding current is flowing. In addition, the movable contact 17 is downwardly supported by a spring 18 below the rectangular through hole 16 of the plate support 15 so that the movable contact 17 is fixed to the fixed contact 8, 8 ′ by the spring 18. Keep contact with).
