Description

작동상태 표시형 릴레이{Operating state display type relay}Operating state display type relay}

본 발명은 여러 가지 입력신호에 따라 회로를 개폐시키는 릴레이에 관한 것으로, 특히 릴레이의 작동상태를 정확하게 확인할 수 있는 작동상태 표시형 릴레이에 관한 것이다.The present invention relates to a relay for opening and closing a circuit according to various input signals, and more particularly to an operating state display type relay capable of accurately checking the operating state of the relay.

일반적으로, 릴레이(relay)란 전압, 전류, 전력, 주파수 등의 전기 신호를 비롯하여 온도, 빛 등 여러 가지 입력 신호에 따라 전기 회로의 개폐를 변환시키는 계전기로서, 도 1 및 도 2에 도시한 바와 같이, 릴레이코일(3)의 S1단자와 S2단자에 신호가 입력되어 S1단자와 S2단자에 전류가 유기되면 릴레이접점(5)의 B+단자와 L단자가 붙게(연결;CLOSE) 되어 상기 릴레이접점(5)의 B+단자와 L단자가 도통상태가 되므로 릴레이접점(5)에 연결된 부하(도시안됨)가 작동하게 된다.In general, a relay is a relay that converts the opening and closing of an electrical circuit according to various input signals such as temperature and light, as well as electrical signals such as voltage, current, power, and frequency, and the like, as shown in FIGS. 1 and 2. Likewise, when a signal is input to the S1 terminal and the S2 terminal of the relay coil 3, and current is induced in the S1 terminal and the S2 terminal, the B + terminal and the L terminal of the relay contact 5 are connected (CLOSE) to the relay contact point. Since the B + terminal and the L terminal of (5) are in a conductive state, the load (not shown) connected to the relay contact 5 is operated.

그런데, 이와 같은 종래의 릴레이에 있어서, 릴레이(1)의 작동여부를 확인하기 위해서는 릴레이(1)에 연결된 부하의 작동을 확인하거나 릴레이(1)의 작동음을 직접 들음으로서 가능하였으나, 릴레이(1)의 단품불량 등으로 릴레이코일(3) S1단자와 S2단자에 전류가 유기되더라도 릴레이접점(5) B+단자와 L단자가 붙지 않고 작동음만 울릴 경우 부하가 작동되지 않으므로, 현장에서는 불량의 원인을 찾기 위해 릴레이(1)에 연결된 회로를 모두 체크해야 하는 작업이 필요하며 이로 인해 많은 시간과 노력이 불필요하게 허비된다는 문제점이 있었다.By the way, in the conventional relay, in order to confirm the operation of the relay 1, it was possible to check the operation of the load connected to the relay 1 or to hear the operation sound of the relay 1 directly, the relay (1) Even if current is induced in the relay coil (3) S1 and S2 terminals due to a single unit defect, the load will not operate if the relay contacts (5) B + and L terminals do not stick and only the operation sound sounds. It is necessary to check all the circuits connected to the relay (1) in order to find a problem, which causes a lot of unnecessary time and effort wasted.

따라서, 본 발명은 상술한 종래의 문제점을 해결하기 위하여 안출된 것으로, 릴레이접점의 연결상태에 따라 작동되는 릴레이 작동상태 표시용 램프를 릴레이코일의 S2단자와 릴레이접점의 L단자에 병렬로 연결하여 릴레이코일에 전류가 유기되더라도 릴레이접점이 붙지 않는 단품불량 등 릴레이의 이상유무를 표시용 램프를 통해 정확하고도 신속하게 확인할 수 있는 작동상태 표시형 릴레이를 제공하는데 그 목적이 있다.Accordingly, the present invention has been made to solve the above-mentioned conventional problems, by connecting a relay operating state display lamp which is operated according to the connection state of the relay contact to the S2 terminal of the relay coil and the L terminal of the relay contact in parallel. It is an object of the present invention to provide an operation status display type relay that can accurately and quickly check the status of a relay, such as a defect in a single part that does not have a relay contact even when current is induced in the relay coil.

이하, 상기와 같이 구성된 작동상태 표시형 릴레이의 작용효과를 설명한다.Hereinafter, the effect of the operation state display relay configured as described above will be described.

먼저, 릴레이코일(30)의 S1단자와 S2단자에 전압, 전류, 전력, 주파수 등의 전기 신호를 비롯하여 온도, 빛 등 여러 가지 신호가 입력되어 S1단자와 S2단자에 전류가 유기되면, 전자석의 원리에 따라 릴레이접점(40)의 B+단자와 L단자가 붙게(연결;CLOSE)된다.First, when electrical signals such as voltage, current, power, and frequency are input to the S1 and S2 terminals of the relay coil 30, various signals such as temperature and light are input, and current is induced to the S1 and S2 terminals. According to the principle, the B + terminal and the L terminal of the relay contact 40 are connected (CLOSE).

상기 릴레이접점(40)의 B+단자와 L단자가 붙게 되면, 릴레이코일(30)의 S2단자와 릴레이접점(40)의 L단자에 병렬로 연결된 표시용 램프(50)가 작동되어 릴레이(10)의 작동과 함께 릴레이(10)의 작동상태 표시창(20) 또는 표시창용 인디게이터(60)를 통해 표시용 램프(50)가 점등되므로 릴레이(10)가 정상작동상태임을 확인할 수 있다.When the B + terminal and the L terminal of the relay contact 40 are attached, the display lamp 50 connected in parallel to the S2 terminal of the relay coil 30 and the L terminal of the relay contact 40 is operated to relay 10 With the operation of the operation state display window 20 of the relay 10 or the display lamp indicator 60 through the display window indicator 60, the relay 10 can be confirmed that the normal operating state.

한편, 릴레이(10)의 단품불량 등으로 릴레이코일(30)의 S1단자와 S2단자에 전류가 유기되더라도 릴레이접점(40)의 B+단자와 L단자가 붙지 않게 되면, 릴레이접점(40)의 L단자에 연결된 표시용 램프(50)에 전원이 인가되지 않기 때문에 표시용 램프(50)가 작동하지 않게 되므로 릴레이(10)가 미작동상태임을 확인할 수 있다.On the other hand, even if current is induced in the S1 terminal and the S2 terminal of the relay coil 30 due to a defective part of the relay 10 or the like, when the B + terminal and the L terminal of the relay contact 40 do not stick, the L of the relay contact 40 Since no power is applied to the display lamp 50 connected to the terminal, the display lamp 50 does not operate, and thus the relay 10 may be in an inoperative state.

따라서, 릴레이코일(30)에 전류가 유기되더라도 릴레이접점(40)이 붙지 않는 단품불량 등 릴레이(10)의 작동상태를 현장에서 표시용 램프(50)의 점등여부에 따라 정확하고도 신속하게 확인할 수 있으므로 릴레이(10)에 연결된 회로를 모두 체크해야 하는 불필요한 작업을 없앨 수 있게 된다.Therefore, even if a current is induced in the relay coil 30, the operation state of the relay 10, such as a defective part that does not adhere to the relay contact 40, can be checked accurately and quickly according to whether the display lamp 50 is turned on in the field. Therefore, unnecessary work to check all the circuits connected to the relay 10 can be eliminated.

상기의 설명에서와 같이 본 발명에 의한 작동상태 표시형 릴레이에 의하면, 릴레이접점의 연결상태에 따라 작동되는 릴레이 작동상태 표시용 램프를 릴레이코일의 S2단자와 릴레이접점의 L단자에 병렬로 연결하여 릴레이코일에 전류가 유기되더라도 릴레이접점이 붙지 않는 단품불량 등 릴레이의 이상유무를 표시용 램프를 통해 정확하고도 신속하게 확인할 수 있으므로 릴레이에 연결된 회로를 모두 체크해야 하는 불필요한 작업을 없앨 수 있다는 효과가 있다.According to the operation state display type relay according to the present invention as described above, by connecting the relay operation state display lamp which is operated in accordance with the connection state of the relay contact to the S2 terminal of the relay coil and the L terminal of the relay contact in parallel Even if the current is induced in the relay coil, the abnormality of the relay, such as a defective part that does not have a relay contact point, can be checked accurately and quickly through the indicator lamp, eliminating the unnecessary work of checking all the circuits connected to the relay. have.
