본 고안은 전자접촉기의 도선연결장치에 관한 것으로서, 더욱 상세하게는 배 선작업이 간편한 전자접촉기의 도선연결장치에 관한 것이다.The present invention relates to a wire connecting device of a magnetic contactor, and more particularly, to a wire connecting device of a magnetic contactor that is easy to wire work.

전자접촉기는 전기회로를 기계적으로 직접 차단하거나 접속하는 역할을 하는 전자기기로서, 과부하 계전기와 함께 전자개폐기를 구성하여 모터 등의 과부하 소손을 방지한다.A magnetic contactor is an electronic device that serves to mechanically block or connect an electric circuit directly. An electromagnetic contactor is configured together with an overload relay to prevent overload damage of a motor.

이러한 전자접촉기는 본체프레임의 내부에 전자석부와 접점부가 설치되어, 전자석의 코일 양단에 전원이 인가되면 접점부의 접점이 폐로되면서 전원측 회로가 부하측 회로와 연결되어 부하에 전원공급이 이루어지고, 반대로 전자석 코일 양단에 공급되는 전원이 차단되면 접점부의 접점이 개로되면 부하에 공급되던 전원이 차단되도록 한다.The magnetic contactor is provided with an electromagnet part and a contact part inside the main body frame. When power is applied to both ends of the coil of the electromagnet, the contact part of the contact part is closed and the power supply circuit is connected to the load side circuit to supply power to the load. When the power supplied to both ends of the coil is cut off, when the contact is opened, the power supplied to the load is cut off.

도 1은 종래 전자접촉기를 나타낸 사시도이고, 도 2는 도 1의 전자접촉기의 단면도이며, 도 3은 도 1의 전자접촉기의 도선연결장치의 측면도이다.1 is a perspective view illustrating a conventional magnetic contactor, FIG. 2 is a cross-sectional view of the magnetic contactor of FIG. 1, and FIG. 3 is a side view of the wire connection device of the magnetic contactor of FIG. 1.

Includes a lug 34 installed therein.

상기 와셔(31)는 단자(20)와의 사이에 결합되는 도선이 마찰력에 의해 이탈이 방지되도록, 단자(20)와 마주하는 면이 톱니형상처럼 거칠게 형성된다. 여기서, 상기 단자(20)의 와셔(31)와 마주하는 면도 마찬가지로 톱니형상처럼 거칠게 형성된다.The washer 31 has a surface facing the terminal 20 so as to be coarse in shape so as to prevent the conducting wires coupled with the terminal 20 from being separated by the frictional force. Here, the shaving facing the washer 31 of the terminal 20 is formed roughly like a sawtooth shape.

상기 탄성체(32)는 일단이 러그(34)의 내면에 지지되고 타단이 와셔(31)에 접촉되도록 설치되며, 와셔(31)를 단자(20)방향으로 밀어주도록 스프링이 사용되는 것이 바람직하다.The elastic body 32 is installed so that one end is supported on the inner surface of the lug 34 and the other end is in contact with the washer 31, the spring is used to push the washer 31 in the direction of the terminal 20.

이하, 본 고안의 전자접촉기의 도선연결장치의 작동을 설명하면 다음과 같다.Hereinafter, the operation of the wire connecting device of the magnetic contactor of the present invention will be described.

도 6은 도 5의 도선연결장치의 컨택터홀더가 눌려진 상태의 도면이다.6 is a view illustrating a state in which a contactor holder of the wire connection device of FIG. 5 is pressed.

도 6을 참조하면, 상기 컨택터홀더(33)를 A방향으로 누르면, 컨택터홀더(33)가 고정되는 와셔(31)는 A방향으로 이동되면서 단자(20)와 이격되고, 탄성체(32)는 눌리게 된다. 컨택터홀더(33)를 누른 상태에서 와셔(31)와 단자(20)의 사이에 도선의 단자부를 삽입시키고 컨택터홀더(33)에 가한 힘을 제거하면, 눌려있던 탄성체(32)의 복원력에 의해 와셔(31) 및 컨택터홀더(33)가 B방향으로 이동된다. 이때, 도선은 와셔(31)와 단자(20)의 사이에 고정되고 와셔(31)와 단자(20)의 톱니형상에 의해 이탈이 방지되어, 도선과 단자(20)의 연결이 완료된다.Referring to FIG. 6, when the contactor holder 33 is pressed in the A direction, the washer 31 to which the contactor holder 33 is fixed is spaced apart from the terminal 20 while moving in the A direction, and the elastic body 32 is disposed. Will be pressed. When the contactor holder 33 is pressed and the terminal portion of the conductive wire is inserted between the washer 31 and the terminal 20 and the force applied to the contactor holder 33 is removed, the restoring force of the pressed elastic body 32 is reduced. The washer 31 and the contactor holder 33 are then moved in the B direction. At this time, the conducting wire is fixed between the washer 31 and the terminal 20, the separation is prevented by the sawtooth of the washer 31 and the terminal 20, the connection of the conducting wire and the terminal 20 is completed.

즉, 도선을 단자(20)에 연결하기 위해서는 컨택터홀더(33)를 누르고 도선을 단자(20)와 와셔(31)의 사이에 삽입하면 된다.That is, in order to connect the wire to the terminal 20, the contactor holder 33 may be pressed and the wire may be inserted between the terminal 20 and the washer 31.

이처럼, 탄성력을 이용하면, 스크류(9a, 도 3)를 매번 조립하는 것보다 간편하게 배선작업을 할 수 있다.In this way, when the elastic force is used, wiring can be performed more easily than assembling the screw 9a (FIG. 3) every time.

이상에서 본 바와 같이, 본 고안에 따른 전자접촉기의 도선연결장치에 의하면, 스크류를 제거하여 배선의 신속성이 향상되는 이점이 있다.As seen above, according to the conductor connecting device of the magnetic contactor according to the present invention, there is an advantage that the speed of the wiring is improved by removing the screw.
