본 고안은 누전차단기 받침구에 관한 것으로, 보다 상세하게는 나사고정방식을 배제하면서도 배전반에 누전차단기를 착탈식으로 안정하게 결합시킬 수 있도록 된 누전차단기 받침구에 관한 것이다.The present invention relates to a ground fault circuit breaker support, and more particularly, to a ground fault circuit breaker support that can be detachably and stably coupled to the switchgear while eliminating the screw fixing method.

일반적으로, 배전반에는 전기의 누전시 자동으로 전원경로를 단락시켜 전기누전시 초래되는 감전 및/또는 화재로의 연계가능성을 차단하기 위한 최소한 하나 이상의 누전차단기가 설치된다.In general, at least one earth leakage circuit breaker is installed in the switchboard to automatically short-circuit the power path to cut off the possibility of electric shock and / or fire caused by the electric leakage.

도 1은 종래의 일예에 따른 누전차단기 받침구를 나타낸 도면으로, 배전반(도시는 생략)에 설치될 누전차단기(10)는 그 양측면에 나사수납요홈(12)이 형성되고, 그 나사수납요홈(12)내에는 고정나사공(14)이 형성되며, 그 고정나사공(14)을 통해 대응하는 고정나사(16)가 관통하여 배전반에 고정된 차단기받침구(18)의 양측에 형성된 나사결합공에 체결되고, 그에 따라 해당하는 누전차단기(10)가 차단기받침구(18)에 안정적으로 결합된다.1 is a view showing a ground fault breaker supporter according to a conventional example, the ground fault breaker 10 to be installed in the switchboard (not shown) is formed on both sides of the screw receiving grooves 12, the screw receiving groove ( 12) a fixing screw hole 14 is formed in the screw coupling holes formed on both sides of the circuit breaker support 18 fixed to the switchboard through a corresponding fixing screw 16 through the fixing screw hole 14 Is coupled to, the corresponding earth leakage breaker 10 is stably coupled to the circuit breaker support (18).

그런데, 도 1에 도시된 종래의 일예에 따른 누전차단기 받침구의 구조에서는 누전차단기(10)의 양측에 형성된 각 나사수납요홈(12)의 고정나사공(14)을 통해 상기 고정나사(16)를 관통시켜 상기 차단기받침구(18)의 나사결합공에 체결되도록 하기 때문에, 고정나사(16)가 부가적으로 필요할 뿐만 아니라 그 고정나사(16)에 의한 누전차단기(10)의 장착 및/또는 분리 작업에도 상당한 시간이 소요된다.However, in the structure of the earth leakage breaker receiving hole according to the conventional example shown in FIG. 1, the fixing screw 16 is provided through the fixing screw holes 14 of the respective screw receiving recesses 12 formed on both sides of the earth leakage breaker 10. In order to penetrate the screwing hole of the circuit breaker support 18, not only the fixing screw 16 is additionally required, but also the mounting and / or removal of the ground fault circuit breaker 10 by the fixing screw 16. The work also takes considerable time.

더구나, 배전반에 다수의 누전차단기를 장착하거나 분리하는 경우에 상당한 작업시간이 걸리게 되어 불리하게 된다.In addition, when a large number of earth leakage breakers are installed or removed in the switchboard, a considerable time is taken, which is disadvantageous.

본 고안은 상기한 종래 기술을 감안하여 이루어진 것으로, 배전반에 고정된 차단기받침구에 별도의 고정나사를 사용하지 않으면서도 누전차단기가 안정적으로 착탈되도록 한 누전차단기 받침구를 제공함에 그 목적이 있다.The present invention has been made in view of the above-described prior art, and an object thereof is to provide an earth leakage breaker support hole for stably detaching the earth leakage breaker without using a separate fixing screw in the breaker support hole fixed to the switchboard.

상기한 목적을 달성하기 위해, 본 고안의 바람직한 실시예에 따르면 양측에 고정요홈이 형성된 누전차단기가 장착되는 누전차단기 받침구에 있어서, 중앙 연결부의 양단에 상기 누전차단기의 양측 저면이 지지되는 차단지지면이 형성되고, 각 차단기지지면에는 상기 누전차단기의 이탈을 방지하기 위한 외단벽이 형성되며, 각 차단기지지면의 외단벽에는 상기 누전차단기의 고정요홈에 대응하여 결합돌기가 일체로 형성되고, 그 결합돌기의 내면에는 상기 누전차단기의 상기 고정요홈에 걸리는 결합턱이 형성되며, 상기 차단기지지면의 외단벽의 외측에 형성되는 배전반결합면에는 고정장공이 형성된 누전차단기 받침구가 제공된다.In order to achieve the above object, according to a preferred embodiment of the present invention in the ground fault circuit breaker support that is equipped with a ground fault circuit breaker is formed on both sides, the blocking paper is supported on both ends of the ground fault circuit breaker at both ends of the central connection portion; A ground is formed, and each breaker base is formed with an outer end wall for preventing the leakage of the ground fault breaker, and an outer end wall of each breaker base ground is formed with a coupling protrusion integrally corresponding to the fixing recess of the ground fault breaker. A coupling jaw is formed on the inner surface of the coupling protrusion and is fixed to the fixing recess of the ground fault interrupter, and a switchboard coupling surface formed at an outer side of the outer end wall of the ground of the breaker base is provided with a ground fault breaker supporter having a fixed hole.

바람직하게, 상기 결합돌기의 외측에는 수직방향으로 보강리브가 일체로 형성된다.Preferably, the outer side of the engaging projection is integrally formed with a reinforcing rib in the vertical direction.

또, 본 고안에 따르면 상기 누전차단기 받침구는 개별적으로 형성되어도 되지만, 인접한 위치에 분리선을 개재하여 다수개가 일체로 형성되어도 된다.In addition, according to the present invention, the earth leakage breaker base openings may be formed separately, but a plurality of the earth leakage breaker support ports may be integrally formed with a separation line at an adjacent position.

도 5는 본 고안에 따른 누전차단기 받침구가 다수개 일체로 성형된 상태를 나타내고, 도 6은 도 5에 도시된 다수개의 누전차단기 받침구상에 다수의 누전차단기가 결합된 상태를 나타낸다.FIG. 5 illustrates a state in which a plurality of earth leakage breaker supporters are integrally formed, and FIG. 6 illustrates a state in which a plurality of earth leakage breakers are coupled to the plurality of earth leakage breaker supporters shown in FIG. 5.

즉, 도 5를 참조하면, 다수(본 고안에서는 대략 12개)의 누전차단기 받침구(20A∼20N)가 분리선(20b)에 의해 분리된 상태로 성형되는 바, 그 다수개의 누전차단기 받침구(20A∼20N)에 대해 누전차단기(10)의 설치 수에 대응하는 위치의 분리선(20b)을 절단하여 배전반(도시 생략)에 고정시키고서 각 누전차단기 받침구(20A,---,20N)상에 각 누전차단기(10A,---,10N)를 도 2 내지 도 4에 설명된 형태로 각 누전차단기 받침구(20A,---,20N)의 결합돌기의 결합턱에 의해 간단하게 장착할 수 있게 된다. That is, referring to Figure 5, a plurality (approximately 12 in the present invention) of the earth leakage breaker support holes 20A to 20N are formed in a state separated by the separation line 20b, the plurality of earth leakage breaker support holes ( Cut the separation line 20b at a position corresponding to the number of installed the earth leakage breaker 10 with respect to 20A to 20N, and fix it to a switchboard (not shown), respectively, on each earth leakage breaker support hole 20A, ---, 20N. Each earth leakage breaker 10A, ---, 10N can be simply mounted by the engaging jaw of the engaging projection of each earth leakage breaker support hole 20A, ---, 20N in the form described in FIGS. It becomes possible.

한편, 본 고안은 상기한 적용예로 한정되지는 않고 누전차단기의 양측에 형성된 고정요홈을 지지하기 위해 누전차단기 받침구의 양측에 결합돌기및 결합턱이 형성된 구조이면 고안의 기술적 요지및 요점을 이탈하지 않는 범위 내에서 다양한 변경 및 변형 실시가 가능함은 물론이다.On the other hand, the present invention is not limited to the above application example, if the coupling protrusion and the coupling jaw is formed on both sides of the earth leakage breaker support port to support the fixing grooves formed on both sides of the earth leakage breaker does not depart from the technical gist and gist of the invention. Various changes and modifications can be made without departing from the scope of the invention.

상기한 바와 같이, 본 고안에 따른 누전차단기 받침구에 의하면 누전차단기의 양측에 형성된 고정요홈에 대응하여 결합돌기가 형성되기 때문에, 그 누전차단 기 받침구에 누전차단기를 장착하는 경우에 별도의 고정나사가 배제된 상태에서 간단하게 장착 및 분리가 가능하게 된다.As described above, according to the earth leakage breaker supporter according to the present invention, since the engaging projection is formed corresponding to the fixing grooves formed on both sides of the earth leakage breaker, when the earth leakage breaker is mounted on the earth leakage breaker supporter It is possible to simply attach and detach with the screw removed.
