본 고안은 전기회로를 개폐하고 단락사고등 전기 사용에 따른 사고를 미연에 방지하기 위해 사용되는 배선용 차단기에 관한 것으로, 보다 구체적으로는 차단기의 개폐조작부인 핸들과 접점부인 가동접촉자 사이의 마찰력을 최소화시켜 작동을 원활하게하고 조립공정을 간소화 할 수 있는 핸들과 가동접촉자의 연결장치를 제공하기 위한 것이다.The present invention relates to a circuit breaker used to open and close an electric circuit and prevent an accident caused by the use of electricity such as a short circuit accident. It is to provide a connection device of the handle and the movable contactor to facilitate the operation and simplify the assembly process.
일반적으로 종래 배선용 차단기는 첨부도면 제1도와 같이 개폐조작부인 핸들(13), 핸들의 조작에 따라 움직이는 가동접촉자(14), 케이스(7)에 고정된 고정접촉자(8), 과전류를 검지하는 바이메탈(10), 바이메탈(10)에 접속된 부하측 단자(11), 가동접촉자와 바이메탈 사이에 연결된 연동연선(12)등으로 구성되어 있다.In general, a conventional circuit breaker includes a handle 13 which is an opening / closing operation part, a movable contactor 14 moving according to the operation of the handle, a fixed contactor 8 fixed to the case 7, and a bimetal detecting an overcurrent as shown in FIG. (10), a load side terminal 11 connected to the bimetal 10, and an interlocking twisted pair 12 connected between the movable contactor and the bimetal.
따라서 핸들(13)을 조작하여 차단기를 투입 (ON)시키면 가동접촉자(14)의 가동접점(15)이 고정접촉자(8)의 고정접점(9)과 접촉하여 고정접촉자와 부하측 단자(11) 사이에 통전이 이루어지고, 반대로 핸들(13)을 OFF상태로 위치시키면 가동접촉자(14)가 이동하여 가동접점이 고정접점에서 떨어지므로 회로는 차단된다.Accordingly, when the breaker is operated by turning on the handle 13, the movable contact 15 of the movable contactor 14 is in contact with the fixed contact 9 of the fixed contactor 8 between the fixed contactor and the load side terminal 11. If the handle 13 is placed in the OFF state, the movable contact 14 moves to move the contact point away from the stationary contact, so that the circuit is cut off.
상기와 같은 종래 배선용 차단기에 설치된 핸들(13)과 가동접촉자(14)는 제2도와 같은 형상으로 되어 있다.The handle 13 and the movable contact 14 provided in the conventional wiring breaker as described above have a shape as shown in FIG.
즉, 핸들(11)에는 가동접촉자가 조립될 수 있는 크기의 공간부(13a)를 형성하고 가동접촉자(14)에는 공간부내로 끼워질 수 있는 한쌍의 지지각(14a)과 원형돌기부(14b)를 형성한 구조로 되어 있으며, 조립시 지지각(14a)부분을 핸들(13)의 공간부(13a)내로 끼우면 원형돌기부(14b)가 공간부내에 형성된 홈부(13b)에 끼워져 결합되게 하였다.That is, the handle 11 is formed with a space portion 13a having a size to which the movable contactor can be assembled, and the movable contactor 14 has a pair of support angles 14a and the circular protrusion 14b that can be fitted into the space. When the assembly of the support angle (14a) is inserted into the space portion (13a) of the handle 13, the circular projection (14b) is fitted into the groove portion (13b) formed in the space portion to be coupled.
그러나 상기와 같은 종래 장치는 핸들(13)과 가동접촉자(14)가 두점(원형돌기부)에 의해 지지되는 구조이어서 핸들 조작시 핸들과 가동 접촉자 사이에 마찰력이 크게 작용하게 되고 이에 따라 작동이 원활하지 못하게 됨은 물론 심한 경우 작동불능의 원인이 되기도 한다.However, the conventional apparatus as described above has a structure in which the handle 13 and the movable contactor 14 are supported by two points (circular protrusions), so that the friction force acts greatly between the handle and the movable contactor when the handle is operated, and thus the operation is not smooth. Not only that, but in severe cases it can also cause malfunction.
또한 핸들과 가동접촉자의 외형이 커져 재료비의 증가를 초래하고 조립공정의 증가를 가져오게 되며, 가동접촉자의 지지각을 평행하게 유지시키기 위한 별도의 공구가 필요해지는 결점도 있다.In addition, the appearance of the handle and the movable contactor increases, resulting in an increase in the material cost and an increase in the assembly process, and there is a disadvantage that a separate tool is required to keep the support angle of the movable contactor in parallel.
본 고안의 목적은 핸들과 가동접촉자를 일점 지지구조에 의해 결합하여 가동접촉자의 작동을 원활하게 하고 아울러 재료비와 조립 공정의 감소를 가져올 수 있느 핸들과 가동접촉자의 연결 장치를 제공하기 위한 것이다.An object of the present invention is to provide a connection device of the handle and the movable contactor by combining the handle and the movable contactor by the one-point support structure to facilitate the operation of the movable contactor and reduce the material cost and the assembly process.
이하 본 고안 장치를 첨부된 도면 제3도와 제5도에 의해 상세하게 설명한다.Hereinafter, the device of the present invention will be described in detail with reference to FIGS. 3 and 5.
핸들(1)에는 소정의 두께로된 지지편(2)이 형성되어 있고 상기 지지편에 체결공(3)이 형성되어 있으며, 상기 체결공은 핸들이 중심선과 일치하는 위치에 있다.The handle 1 is formed with a support piece 2 having a predetermined thickness and a fastening hole 3 is formed in the support piece, and the fastening hole is at a position where the handle coincides with the center line.
가동접촉자(4)에는 가동접점(6)이 고정되어 있고 일측에는 돌출된 형상의 체결돌기(5)가 형성되어 있으며, 상기 체결돌기는 가동접촉자(4)의 일부분을 90°각도로 절곡하는 수단에 의해 형성된다.A movable contact 6 is fixed to the movable contact 4 and a fastening protrusion 5 having a protruding shape is formed at one side, and the fastening protrusion is a means for bending a part of the movable contact 4 at an angle of 90 °. Is formed by.
또한 핸들에 형성된 체결공(3)은 직경이 다른 2개의 원이 합쳐진형으로 되어 있다.In addition, the fastening hole (3) formed in the handle is a combination of two circles of different diameters In form.
따라서 가동 접촉자(4)의 체결돌기(5)를 핸들(1)의 체결공(3)으로 끼우면, 체결돌기(5)는 체결공(3)에서 자유롭게 회전하지 않는 상태로 결합되며, 핸들의 조작에 의해 가동 접촉자는 체결돌기를 축으로 회전운동을 하게 된다.Therefore, when the fastening protrusion 5 of the movable contactor 4 is inserted into the fastening hole 3 of the handle 1, the fastening protrusion 5 is coupled in a state that does not rotate freely in the fastening hole 3, and the manipulation of the handle is performed. By this, the movable contactor makes a rotational movement about the fastening protrusion about its axis.
그리고 가동접촉자의 일측면은 차단기 케이스에 지지되어 체결돌기(5)가 체결공(3)으로부터 이탈되지 않는다.One side of the movable contact is supported by the breaker case so that the fastening protrusion 5 is not separated from the fastening hole 3.
상기와 같이 된 본 고안은 핸들(1)과 가동접촉자(4)가 한점에 의해 연결되어 있고 또한 체결공(3)이 핸들의 중심선에 위치되어 있으므로 핸들 조작시 핸들과 가동접촉자 사이에서 발생하는 마찰저항이 최소화되며, 따라서 가동접촉자(4)의 원활한 작동이 원활해진다.According to the present invention as described above, since the handle 1 and the movable contactor 4 are connected by one point and the fastening hole 3 is located at the center line of the handle, friction generated between the handle and the movable contactor when the handle is operated. The resistance is minimized, and thus smooth operation of the movable contactor 4 is smoothed.
또한 핸들과 가동접촉자가 한점으로 연결됨에 따라 핸들에 가동접촉자의 연결을 위한 별도의 공간부를 형성할 필요가 없게되고 가동접촉자에도 한쌍의 지지각을 형성할 필요가 없게 되므로 부품의 소형화가 가능해지며, 재료비의 절감한 조립공정의 간소화를 가져올 수 있게 되는 효과가 있다.In addition, since the handle and the movable contactor are connected as one point, it is not necessary to form a separate space for connecting the movable contactor to the handle, and it is not necessary to form a pair of support angles to the movable contactor, thereby miniaturizing parts. There is an effect that can bring a simplified assembly process of reduced material costs.
