본 발명의 일 실시 예에 따른 배선 차단기 가동 접촉자 제조과정을 도 1 내지 도 7을 통해 살펴보면 다음과 같다.A process of manufacturing a movable contactor for a wire breaker according to an embodiment of the present invention will be described with reference to FIGS. 1 to 7 .

<프레스 단계><Press step>

먼저, 평판 형태를 이루어 투입된 금속 재질의 가동 원재를 프레스 가공하여 원재 프레임(100) 내측에 도 2에서와같이 선단 날개부(11)와 후단 날개부(12) 형상을 갖는 가동 접촉자(10)가 가공되는 프레스 단계를 실시하게 된다.First, the movable raw material of metal material input in the form of a flat plate is press-processed, and the movable contactor 10 having the shape of the front wing 11 and the rear wing 12 is formed inside the raw material frame 100 as shown in FIG. A press step to be processed is performed.

<1차 절곡단계><1st bending step>

이후, 도 3에서와같이 상기 가동 접촉자(10)의 선단부 양측에 좌우 대칭 형태로 돌출 구비된 선단 날개부(11)를 직각 형태로 절곡시키는 1차 절곡단계를 실시한다.Then, as shown in FIG. 3, a first bending step of bending the tip wing 11 protruding in a left-right symmetrical shape on both sides of the front end of the movable contactor 10 in a right angle shape is performed.

<따내기홈 형성단계><Picking groove formation step>

이와 같이 선단 날개부(11)에 대한 1차 절곡작업이 완료되면, 도 4에서와같이 가동 접촉자(10)의 후단부에 후단 날개부(12)가 돌출 형상을 이루도록 후단부에 일정 깊이로 노칭홈(13)을 형성하게 된다.When the first bending operation for the front wing 11 is completed in this way, as shown in FIG. Ching groove 13 is formed.

이때에는 상기 1차 절곡단계에서 직각 형태로 절곡이 이루어진 선단 날개부(11)를 다시 한번 더 90도 절곡시키는 작업이 함께 실시됨으로써, 절곡 부위가 평면 형태를 이루게 됨을 확인할 수 있다.At this time, it can be seen that the tip wing portion 11, which has been bent at a right angle in the first bending step, is bent by 90 degrees once again, so that the bent portion forms a flat shape.

<2차 절곡단계><Second bending step>

이후, 상기 노칭홈(13)으로 인해 돌출 형태를 이루는 양측 후단 날개부(12)를 절곡시키는 2차 절곡단계를 실시하게 된다.Thereafter, a second bending step of bending both rear end wings 12 forming a protruding shape due to the notching groove 13 is performed.

이때 절곡단계에서는 도 5에서와같이 후단 날개부(12)가 약 75도의 각도로 포밍이 이루어짐이 바람직하다.At this time, in the bending step, as shown in FIG. 5, it is preferable that the rear wing 12 is formed at an angle of about 75 degrees.

<밀착단계><adherence step>

이후, 밀착단계에서는 도 6에서와같이 상기 75도 각도로 절곡이 이루어진 양측 후단 날개부(12)가 상호 밀착되어질 수 있도록 90도로 밀착 포밍이 이루어지게 된다.Thereafter, in the close contact step, as shown in FIG. 6, close forming is performed at 90 degrees so that both rear end wings 12 bent at an angle of 75 degrees can be in close contact with each other.

<피어싱 단계><Piercing step>

상기 과정을 통해 가동 접촉자(10)의 개별 포밍 성형이 완료되면, 선단 날개부(11)와 후단 날개부(12)에 도 7에서와같이 각각 관통공(14,15)을 형성시키는 피어싱 단계를 실시하게 된다.When the individual forming of the movable contact 10 is completed through the above process, a piercing step of forming through holes 14 and 15 in the front wing 11 and the rear wing 12, respectively, as shown in FIG. will be carried out

이와 같이 피어싱 작업이 완료된 본 발명의 가동 접촉자(10)는 원재 프레임(100)으로부터 분리시킴으로써, 도 8 내지 도 10에서와 같은 외관 형상을 이루게 되며, 이후 선단 날개부(11)에 형성된 관통공(14) 부위에 리벳(20) 작업을 통해 도 11에서와같이 리벳팅이 이루어지게 되며, 리벳(20)이 통전 제어를 위한 가동 접점을 이루는 가운데 후단 날개부(12)에 형성된 관통공(15)이 회동축을 이루어 배선 차단기에 설치가 이루어짐과 함께 후단 날개부(12)에 전원선의 연결이 이루어지게 된다.The movable contact 10 of the present invention, after which the piercing operation is completed, is separated from the raw material frame 100 to form an external shape as shown in FIGS. 8 to 10, and then through holes formed in the front wing 11 ( 14) Riveting is performed as shown in FIG. 11 through the rivet 20 work on the part, and the through hole 15 formed in the rear wing 12 while the rivet 20 forms a movable contact for power control. This rotation axis is formed and installed in the wire breaker, and the power line is connected to the rear wing 12.

따라서 본 발명의 배선 차단기 가동 접촉자 제조방법은, 가동 접촉자의 제조 과정에서 약 1.2mm 두께의 금속 원재를 절곡 등의 방식으로 가공하여 필요한 부분만 일정 두께를 유지할 수 있는 제작 방식으로 제작이 이루어지도록 하여 제품의 생산 원가를 절감시킴과 함께 생산성이 향상되는 효과를 나타낸다.Therefore, in the method of manufacturing a movable contactor for a wire breaker of the present invention, in the process of manufacturing a movable contactor, a metal raw material having a thickness of about 1.2 mm is processed by a method such as bending, and only the necessary parts are manufactured in a manufacturing method that can maintain a certain thickness. It reduces the production cost of the product and shows the effect of improving productivity.

한편, 도 12는 본 발명의 다른 실시 예를 나타낸 것으로서, 상기 밀착단계에서는 후단 날개부(12)의 상호 대응되는 면에 밀착 코팅제(12a)를 분사시킨 상태에서 일정 온도(80~120℃)로 가압 밀착이 이루어지게 된다.On the other hand, Figure 12 shows another embodiment of the present invention, in the close contact step at a constant temperature (80 ~ 120 ℃) in a state in which the close contact coating agent (12a) is sprayed on the mutually corresponding surface of the rear wing portion (12). Pressurized adhesion is achieved.

이때 분사되는 밀착 코팅제(12a)는 유기 화합물인 알킬셀레닌산 10~30중량%, 부틸파라벤 10~30중량%, 산화알루미늄 5~20중량%, 다이옥세인 1~20중량%, 세틸피리디늄 클로라이드 10~30중량%의 비율로 혼합 조성을 이룸이 바람직하다.At this time, the adhesion coating agent 12a sprayed is an organic compound, 10 to 30% by weight of alkyl selenic acid, 10 to 30% by weight of butyl paraben, 5 to 20% by weight of aluminum oxide, 1 to 20% by weight of dioxane, cetylpyridinium chloride It is preferable to achieve a mixed composition in a ratio of 10 to 30% by weight.

이와 같이 밀착 코팅제(12a)의 사용이 이루어지게 되면, 후단 날개부(12)의 밀착을 위한 고온 히팅 가압 과정에서 상호 접촉면의 코팅 효과를 통한 변형상태가 안정적으로 유지됨과 함께 밀착력이 향상될 수 있게 된다.In this way, when the use of the adhesion coating agent (12a) is made, the deformation state through the coating effect of the mutual contact surface is stably maintained during the high-temperature heating and pressing process for adhesion of the rear wing portion 12, and the adhesion can be improved do.

특히, 밀착 코팅제(12a)에는 알킬셀레닌산 및 부틸파라벤 성분이 혼합되어 있기 때문에 후단 날개부(12) 접촉면의 열전달 효율이 향상될 수 있으며, 산화알루미늄은 접촉면 표면의 산화 발생을 방지하고, 다이옥세인 및 세틸피리디늄 클로라이드는 각각 코팅제의 점착기능을 향상시킴과 함께 알킬셀레닌산 성분의 촉매 기능을 통하여 양측 후단 날개부(12) 상호간의 밀착 품질이 향상될 수 있게 된다.In particular, since the alkyl selenic acid and butyl paraben components are mixed in the adhesion coating agent 12a, the heat transfer efficiency of the contact surface of the rear wing 12 can be improved, and aluminum oxide prevents oxidation of the contact surface, and dioxin Sein and cetylpyridinium chloride each improve the adhesive function of the coating agent, and through the catalytic function of the alkyl selenic acid component, the quality of adhesion between the rear wing parts 12 on both sides can be improved.

그리고, 상기에서 본 발명의 특정한 실시 예가 설명 및 도시되었지만 본 발명의 가동 접촉자 제조과정이 당업자에 의해 다양하게 변형되어 실시될 수 있음은 자명한 일이다. And, although specific embodiments of the present invention have been described and illustrated above, it is obvious that the manufacturing process of the movable contactor of the present invention can be variously modified and practiced by those skilled in the art.

예를 들면, 상기 실시 예에서는 후단 날개부의 절곡 작업시 75도로 포밍이 이루어지는 상태가 설명 되었으나, 이러한 절곡 각도는 필요에 따라 가변되어질 수 있게 된다.For example, in the above embodiment, the state in which the forming is performed at 75 degrees during the bending operation of the rear wing portion has been described, but this bending angle can be varied as needed.

따라서 이와 같은 변형된 실시 예들은 본 발명의 기술적 사상이나 범위로부터 개별적으로 이해되어져서는 안되며, 이와 같은 변형된 실시 예들은 본 발명의 첨부된 특허청구범위 내에 포함된다 해야 할 것이다.Therefore, such modified embodiments should not be individually understood from the technical spirit or scope of the present invention, and such modified embodiments should be included within the scope of the appended claims of the present invention.
