Description

가역형 전자접촉기의 인터록 장착구조Interlock mounting structure of reversible magnetic contactor

본 고안은 모터의 정,역운전이나, 역상제동(逆相制動)시 사용하는 가역형 전자접촉기에 관한 것으로써, 좀더 구체적으로는 2대의 전자접촉기에 동시에 전원이 인가되므로 인해 쇼트가 발생되지 않도록 기계적으로 방지하는 인터록(interlock)을 장착하는 구조에 관한 것이다.The present invention relates to a reversible magnetic contactor used in the forward and reverse operation of a motor or reverse phase braking. More specifically, a short circuit does not occur because power is applied to two magnetic contactors at the same time. The present invention relates to a structure for mounting an interlock that prevents mechanically.

일반적으로 모터를 정,역회전시키기 위해 2대의 전자접촉기를 사용할 경우에는 2대의 전자접촉기가 동시에 작동하지 않도록 가역형 전자접촉기를 구성하게 된다.In general, when using two magnetic contactors to rotate the motor forward and reverse, the reversible magnetic contactor is configured so that the two magnetic contactors do not operate at the same time.

상기 가역형 전자접촉기는 2대의 전자접촉기를 가역접속(상회전이 역으로 되게 접속)하고 열동계전기(Thermal Relay)를 결합한 것으로 모터의 정,역운전이나, 역상제어(plugging)에 널리 이용되고 있다.The reversible magnetic contactor combines two magnetic contactors with a reversible connection (reversely connected in phase rotation) and a thermal relay, and is widely used for forward / reverse operation of a motor or plugging. .

이러한 가역형 전자접촉기에서 2대의 전자접촉기에 전원이 동시 인가되면 쇼트(short)가 발생되므로 이를 전기적 또는 기계적 인터록을 부가하여 1대의 전자접촉기가 동작할 경우에는 다른 일측의 전자접촉기가 동작되지 않도록 구성된다.When power is applied to two magnetic contactors at the same time in this reversible magnetic contactor, a short is generated. Therefore, when one magnetic contactor operates by adding an electrical or mechanical interlock, the magnetic contactor of the other side is not operated. do.

도 1은 종래의 인터록 장착구조를 나타낸 분해 사시도로써, 인터록(2)의 양측면으로 돌출된 가동부돌기(3)를 전자접촉기(1a)(1b)의 일측면에 형성된 삽입홈(4)내에 각각 끼워 상기 인터록(2)이 전자접촉기 사이에 위치되도록 되어 있다.1 is an exploded perspective view illustrating a conventional interlock mounting structure, in which movable part protrusions 3 protruding from both sides of an interlock 2 are respectively inserted into insertion grooves 4 formed on one side of the magnetic contactors 1a and 1b. The interlock 2 is located between the magnetic contactors.

이때 상기 전자접촉기(1a)(1b)의 조립방향(전원공급측과 부하측)이 일치하는지를 조립전에 반드시 확인하여야 된다.At this time, the assembly direction (power supply side and load side) of the magnetic contactor (1a) (1b) must be confirmed before assembly.

이에 따라 일측의 전자접촉기(1a)가 동작될 경우에는 인터록(2)에 의해 다른 일측의 전자접촉기(1b)는 동작하지 않는다.Accordingly, when the magnetic contactor 1a of one side is operated, the magnetic contactor 1b of the other side is not operated by the interlock 2.

상기한 바와 같이 전자접촉기(1a)(1b) 사이에 설치되어 일측의 전자접촉기만이 동작되도록 하는 인터록(2)은 상기 전자접촉기의 용량 또는 모델의 변화에 따라 크기가 각각 다르므로 인해 별도의 받침판(도시는 생략함)을 사용하여 전자접촉기(1a)(1b) 사이에 설치하거나, 도 1과 같이 인터록(2)의 저면에 한쌍의 다리(5)를 형성하여 용량에 따라 알맞는 인터록을 선택하여 사용하도록 되어 있으므로 부품관리가 번거롭게 된다.As described above, the interlock 2 installed between the magnetic contactors 1a and 1b so that only one side of the magnetic contactor is operated is different in size depending on the capacity of the magnetic contactor or the change of the model. (Not shown) is installed between the magnetic contactor (1a) (1b), or a pair of legs (5) formed on the bottom surface of the interlock 2 as shown in Figure 1 to select the appropriate interlock according to the capacity Parts management is cumbersome since it is to be used.

본 고안은 종래의 이와 같은 문제점을 해결하기 위해 안출한 것으로써, 전자접촉기의 용량 또는 모델이 변경되더라도 모든 전자접촉기에 적용가능하도록 하는데 그 목적이 있다.The present invention has been made to solve such a problem in the prior art, and its purpose is to be applicable to all magnetic contactors even if the capacity or model of the magnetic contactor is changed.

상기 목적을 달성하기 위한 본 고안의 형태에 따르면, 전자접촉기의 삽입홈내에 인터록의 가동부돌기가 끼워지도록 상기 인터록를 전자접촉기 사이에 위치시키도록 된 것에 있어서, 상기 인터록의 양측면에 한쌍의 돌기를 형성하고 상기 인터록이 접속되는 전자접촉기에는 돌기가 삽입되는 결합홈을 형성하여서 된 가역형 전자접촉기의 인터록 장착구조가 제공된다.According to an aspect of the present invention for achieving the above object, the interlock is positioned between the magnetic contactor so that the movable part projection of the interlock is inserted into the insertion groove of the magnetic contactor, and a pair of projections are formed on both sides of the interlock. The interlock mounting structure of the reversible magnetic contactor is provided in the electromagnetic contactor to which the interlock is connected to form a coupling groove into which the projection is inserted.

이하, 본 고안을 일 실시예로 도시한 도 2를 참고로 하여 더욱 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in more detail with reference to FIG. 2 as an embodiment.

도 2는 본 고안의 인터록 장착구조를 나타낸 분해 사시도로써, 본 고안은 인터록(2)의 양측면에 한쌍의 돌기(6)가 형성되어 있고 상기 인터록(2)이 접속되는 전자접촉기(1a)(1b)에는 돌기(6)가 삽입되는 결합홈(7)이 형성되어 있다.FIG. 2 is an exploded perspective view showing an interlock mounting structure of the present invention, in which the pair of protrusions 6 are formed on both sides of the interlock 2, and the magnetic contactor 1a and 1b to which the interlock 2 is connected. ) Is formed with a coupling groove 7 into which the protrusion 6 is inserted.

이와 같이 구성된 본 고안의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above are as follows.

먼저, 모터의 정,역회전 제어를 목적으로 가역형 전자접촉기를 구성하고자 할 경우에는 인터록(2)에 형성된 돌기(6)를 상기 인터록이 접속되는 전자접촉기(1a)의 일측면에 형성된 결합홈(7)내에 끼워주면 된다.First, in order to configure a reversible magnetic contactor for the purpose of controlling the forward and reverse rotation of the motor, the engaging groove formed on one side of the magnetic contactor 1a to which the interlock is connected is formed with the protrusion 6 formed on the interlock 2. It can be inserted in (7).

이에 따라 상기 인터록(2)의 가동부돌기(3)가 크로스 바에 형성된 삽입홈(4)에 끼워지게 되므로 일측의 전자접촉기(1a)와 인터록(2)의 결합작업이 완료된다.Accordingly, the movable projection 3 of the interlock 2 is inserted into the insertion groove 4 formed in the cross bar, so that the coupling operation of the magnetic contactor 1a and the interlock 2 on one side is completed.

이와 같이 일측의 전자접촉기(1a)와의 결합작업이 완료되면 전자접촉기(1a)(1b)의 조립방향(전원공급측과 부하측)이 일치하는지를 확인한 다음 나머지 1개의 전자접촉기(1b)에 형성된 걸림홈(7)을 인터록(2)의 돌기(6)에 끼워주므로써, 전술한 바와 같이 가동부돌기가 삽입홈내에 끼워져 가역형 전자접촉기의 기계적인 인터록제어가 가능해지게 된다.As such, when the coupling operation with the magnetic contactor 1a on one side is completed, the assembly direction (the power supply side and the load side) of the magnetic contactor 1a, 1b is matched, and then the locking grooves formed on the other magnetic contactor 1b ( By fitting 7) to the projection 6 of the interlock 2, as described above, the movable projection is inserted into the insertion groove to enable mechanical interlock control of the reversible magnetic contactor.

상기한 바와 같이 전자접촉기(1a)(1b) 사이에 결합되는 인터록(2)은 전자접촉기의 용량에 구애받지 않고 인터록(2)과의 접속면상의 일정위치에 형성하면 인터록을 호환성있게 사용하게 됨은 이해가능한 것이다.As described above, when the interlock 2 coupled between the magnetic contactors 1a and 1b is formed at a predetermined position on the connection surface with the interlock 2 regardless of the capacity of the magnetic contactor, the interlock is used interchangeably. It is understandable.

이상에서와 같이 본 고안은 전자접촉기의 용량에 구애받지 않고 인터록을 호환성있게 사용하게 되므로 가역절환이 확실히 이루어지게 되고, 또한 사용중에 인터록이 파손되는 현상을 미연에 방지하게 됨은 물론 부품관리가 용이해지게 된다.As described above, the present invention uses the interlock interchangeably regardless of the capacity of the magnetic contactor, so that reversible switching is surely performed, and the interlock is broken during use. You lose.
