Description

기중차단기{AIR CIRCUIT BREAK}Air Circuit Breaker {AIR CIRCUIT BREAK}

본 발명은, 기중차단기에 관한 것으로서, 더욱 상세하게는, 과전류릴레이가 커버에서 용이하게 분리되도록 하여 과전류릴레이의 점검을 용이하게 하고 과전류릴레이를 편리하게 교체할 수 있는 기중차단기에 관한 것이다.The present invention relates to an air circuit breaker, and more particularly, to an air circuit breaker that allows an overcurrent relay to be easily separated from a cover to facilitate inspection of the overcurrent relay and to easily replace the overcurrent relay.

도 1은 종래의 기중차단기의 구조를 도시한 분해사시도이다. 1 is an exploded perspective view showing the structure of a conventional air circuit breaker.

도면에 도시한 바와 같이, 종래의 기중차단기는, 본체(10)와, 과전류릴레이 수용홈(21)이 관통 형성된 커버(20)와, 과전류릴레이 수용홈(21)에 수용되는 과전류릴레이(30)를 포함하여 구성되어 있다. As shown in the drawing, a conventional air circuit breaker includes a main body 10, a cover 20 through which an overcurrent relay accommodation groove 21 is penetrated, and an overcurrent relay 30 accommodated in the overcurrent relay accommodation groove 21. It is configured to include.

커버(20)는 본체(10)의 전면에 나사체결되어 고정결합되며, 과전류릴레이 수용홈(21)의 일측에는 과전류릴레이(30)를 고정 결합시킬 수 있도록 나사산이 그 내주면에 형성된 결합홈(22)이 형성되어 있다. The cover 20 is screwed to the front of the main body 10 is fixedly coupled, one side of the overcurrent relay receiving groove 21, the coupling groove 22 formed on the inner peripheral surface of the screw thread so that the overcurrent relay 30 can be fixedly coupled ) Is formed.

과전류릴레이(30)의 일측에는 과전류릴레이(30)가 과전류릴레이 수용홈(21)에 수용시에 결합홈(22)과 대응하도록 결합부재(31)가 과전류릴레이(30)의 판면 방향을 따라 연장 형성되어 있으며, 결합부재(31)의 중심에는 결합공(31a)이 관통 형성되어 있다. On one side of the overcurrent relay 30, the coupling member 31 extends along the plate surface direction of the overcurrent relay 30 to correspond to the coupling groove 22 when the overcurrent relay 30 is accommodated in the overcurrent relay receiving groove 21. The coupling hole 31a is formed in the center of the coupling member 31.

과전류릴레이(30)는 과전류릴레이 수용홈(21)에 수용되어 결합나사(40)가 결합부재(31)의 결합공(31a)을 관통하여 결합홈(22)에 나사체결되어 고정 결합된다. The overcurrent relay 30 is accommodated in the overcurrent relay receiving groove 21 so that the coupling screw 40 is screwed into the coupling groove 22 through the coupling hole 31a of the coupling member 31 to be fixed.

그런데, 이러한 종래의 기중차단기에 있어서는, 본체(10)에 구비된 과전류릴레이(30)의 고장으로 인한 교체작업이나 혹은 과전류릴레이(30)의 성능 점검시에 과전류릴레이(30)를 본체(10)에서 분리하기 위하여 결합나사(40)를 커버(20)의 결합홈(22)에서 분리한 후 과전류릴레이(30)를 커버(20)의 전면 방향으로 당겨야만 과전류릴레이(30)를 본체(1)에서 분리시킬 수 있으므로 과전류릴레이(30)를 본체(10)에서 분리하는데 장시간이 소요되어 사용자의 불편함을 초래한다는 문제점이 있다. By the way, in the conventional air circuit breaker, the main body 10 receives the over current relay 30 during the replacement operation due to the failure of the over current relay 30 included in the main body 10 or the performance of the over current relay 30. After separating the coupling screw 40 from the coupling groove 22 of the cover 20 to pull the overcurrent relay 30 in the front direction of the cover 20, the overcurrent relay 30 is removed from the main body 1. Since it can be separated from the overcurrent relay 30 takes a long time to separate from the main body 10 there is a problem that causes inconvenience to the user.

따라서, 본 발명의 목적은, 과전류릴레이가 커버에서 용이하게 분리되도록 하여 과전류릴레이의 점검을 용이하게 하고 과전류릴레이를 편리하게 교체할 수 있는 기중차단기를 제공하는 것이다.Accordingly, it is an object of the present invention to provide an air circuit breaker that allows the overcurrent relay to be easily separated from the cover to facilitate the inspection of the overcurrent relay and to easily replace the overcurrent relay.

Figure 2 is a perspective view showing the structure of the air circuit breaker according to an embodiment of the present invention, Figure 3 is a side cross-sectional view of Figure 2, Figure 4 is a side cross-sectional view of FIG.

이들 도면에 도시한 바와 같이, 본 발명의 일 실시예에 따른 기중차단기는, 기중차단기 본체(100)의 전면에 부착되며 과전류릴레이 수용홈(210)이 관통 형성된 커버(200)와; 과전류릴레이 수용홈(210)에 수용되는 과전류릴레이(300)와; 과전류릴레이(300)가 과전류릴레이 수용홈(210)에 슬라이딩 방식으로 수용 및 이탈되도록 커버(200)와 과전류릴레이(300)의 접촉면 중 어느 한 면{실시 예상 과전류 릴레이(300)의 배면}에 형성된 슬라이딩 체결부재(310, 320)와 다른 한 면{실시 예상 커버(200)의 전면}에 형성되어 상기 슬라이딩 체결부재(310, 320)가 체결되는 체결홈(220)을 포함하여 구성되어 있다. As shown in these drawings, the air circuit breaker according to an embodiment of the present invention, the cover 200 is attached to the front of the air circuit breaker main body 100, the overcurrent relay receiving groove 210 is formed through; An overcurrent relay 300 accommodated in the overcurrent relay receiving groove 210; The overcurrent relay 300 is formed on any one surface of the contact surface of the cover 200 and the overcurrent relay 300 (the back surface of the expected overcurrent relay 300) so that the overcurrent relay 300 is accommodated and detached in the overcurrent relay receiving groove 210 in a sliding manner. It is formed on the other side of the sliding fastening member (310, 320) (front surface of the anticipated cover 200) and comprises a fastening groove 220 to which the sliding fastening member (310, 320) is fastened.

상기 슬라이딩 체결부재(310, 320)는, 커버(200)와 접촉되는 과전류릴레이(300)의 배면에 과전류릴레이(300)의 두께 방향을 따라 돌출 형성되는 돌출부(310)와, 돌출부(310)의 단부에서 과전류릴레이(300)의 배면과 소정거리 이격되며 과전류릴레이(300)의 길이 방향을 따라 하측으로 연장되는 연장부(320)로 구성되어 있다. The sliding fastening members 310 and 320 may include protrusions 310 that protrude along the thickness direction of the overcurrent relay 300 on the rear surface of the overcurrent relay 300 in contact with the cover 200, and the protrusions 310. It is composed of an extension 320 which is spaced apart from the rear surface of the overcurrent relay 300 at an end and extends downward along the longitudinal direction of the overcurrent relay 300.

돌출부(310)의 단부에는 체결홈(220)과 접촉하여 과전류릴레이(300)가 커버(200)에 슬라이딩 방식으로 체결되도록 하는 경사지게 형성된 슬라이드면(311)이 구비되어 있다. An end portion of the protrusion 310 is provided with an inclined slide surface 311 in contact with the fastening groove 220 such that the overcurrent relay 300 is fastened to the cover 200 in a sliding manner.

연장부(320)와 커버(200)가 접촉되는 면 중 어느 한 면에는 돌기(230)가 형성되고 다른 한 면에는 돌기(230)가 삽입되는 홈(321)이 형성되어 있다. A protrusion 230 is formed on one surface of the extension part 320 and the cover 200, and a groove 321 is formed on the other surface of the protrusion 230.

과전류릴레이(300)와 커버(200)가 접촉되는 접촉면에는 가이드부(400)가 더 형성되어 있는데, 가이드부(400)는 과전류릴레이(300)의 측면에 과전류릴레이(300)의 판면을 따라 돌출 형성되는 가이드레일(410)과, 가이드레일(410)이 삽입되어 과전류릴레이(300)의 슬라이드 운동을 안내하도록 커버(200)에 형성되는 가이드홈(420)으로 구성되어 있다. The guide portion 400 is further formed on the contact surface between the overcurrent relay 300 and the cover 200, and the guide portion 400 protrudes along the plate surface of the overcurrent relay 300 on the side of the overcurrent relay 300. The guide rail 410 is formed, and the guide rail 410 is inserted into a guide groove 420 formed in the cover 200 to guide the slide movement of the overcurrent relay 300.

이러한 구성에 의하여, 과전류릴레이(300)를 과전류릴레이 수용홈(210)에 결합시에는 우선 과전류릴레이(300)의 일측에 형성된 가이드레일(410)을 커버(200)의 일측에 형성된 가이드홈(420)에 삽입하고 과전류릴레이(300)가 본체(100)에 밀착되는 방향을 따라 과전류릴레이(300)를 밀면, 돌출부(310)에 형성된 슬라이드면(311)이 체결홈(220)의 상단면과 접촉하여 슬라이드 운동됨과 동시에 과전류릴레이(300)가 하측 방향으로 밀리면서 과전류릴레이 수용홈(210)에 수용된다. By this configuration, when the overcurrent relay 300 is coupled to the overcurrent relay receiving groove 210, first, the guide groove 420 formed on one side of the cover 200 includes a guide rail 410 formed on one side of the overcurrent relay 300. When the overcurrent relay 300 is pushed along the direction in which the overcurrent relay 300 is in close contact with the main body 100, the slide surface 311 formed on the protrusion 310 contacts the upper surface of the fastening groove 220. At the same time as the slide motion and the overcurrent relay 300 is pushed in the downward direction is accommodated in the overcurrent relay receiving groove 210.

과전류릴레이(300)가 과전류릴레이 수용홈(210)에 완전히 수용되는 순간 체결홈(220)이 구비된 커버(200)의 배면 주연부에 형성된 돌기(230)가 연장부(320)의 단부에 형성된 홈(321)에 결합되어 과전류릴레이(300)가 과전류릴레이 수용홈(210)에 수용된 상태가 유지되는 것이다. At the moment when the overcurrent relay 300 is completely accommodated in the overcurrent relay accommodating groove 210, the protrusion 230 formed at the periphery of the rear surface of the cover 200 with the fastening groove 220 is formed at the end of the extension 320. The state in which the overcurrent relay 300 is accommodated in the overcurrent relay accommodating groove 210 is maintained at 321.

과전류릴레이(300)를 과전류릴레이 수용홈(210)에서 분리시키는 순서는 과전류릴레이(300)를 과전류릴레이 수용홈(210)에 수용시키는 순서와 역순이므로 그에 대한 상세한 설명은 생략하며, 이러한 체결방식에 의하여 사용자는 과전류릴레이(300)를 과전류릴레이 수용홈(210)에서 용이하게 수용 및 분리할 수 있게 된다. The order of separating the overcurrent relay 300 from the overcurrent relay accommodating groove 210 is the reverse order of the accommodating the overcurrent relay 300 into the overcurrent relay accommodating groove 210, and thus a detailed description thereof will be omitted. As a result, the user can easily receive and separate the overcurrent relay 300 from the overcurrent relay accommodation groove 210.
