본 고안은 각종 자동화기기나 소형모터등의 제어장치에 적용되어 스위칭 기능을 하는 전자 접촉기에 관한 것으로, 보다 구체적으로는 코일단자와 보빈사이에 설치되어 코일단자의 전류를 코일에 통전시키는 역할을 하는 통전스프링을 보빈에 고정시키기 위한 장치에 관한 것이다.The present invention relates to a magnetic contactor that has a switching function applied to various control devices such as automation devices or small motors, and more specifically, is installed between the coil terminal and the bobbin to serve to energize the coil terminal current to the coil. A device for fixing an energizing spring to a bobbin.
일반적으로 전자접촉기는 전자석의 원리를 이용한 스위칭 기구로서, 코일의 연출부에 전원을 인가하면 장에 의해 가동철심이 고정철심에 흡착되고, 이때 가동철심과 결함된 가동접촉자가 함께 이동하면서 연결된 부하를 제어시켜주는 기기이다.In general, a magnetic contactor is a switching mechanism using the principle of an electromagnet, and when power is applied to the directing part of a coil, the movable iron core is attracted to the fixed iron core by the field, and at this time, the movable iron core and the defective movable contactor move together to control the connected load. It is a device that lets you.
제1도는 일반적인 전자 접촉기의 구성을 나타낸 단면도로서 코일(4)이 감겨진 보빈(1)의 일측에 코일단자(2)가 설치되어 있고 상기 코일보빈과 코일단자 사이에는 통전스프링(3)이 설치되어 보빈에 감겨진 코일(4)과 코일단자(2)를 전기적으로 연결시켜 주도록 되어있다.1 is a cross-sectional view showing the configuration of a general electromagnetic contactor, the coil terminal 2 is provided on one side of the bobbin 1, the coil 4 is wound, and an energizing spring 3 is installed between the coil bobbin and the coil terminal. Thus, the coil 4 wound on the bobbin and the coil terminal 2 are electrically connected to each other.
또 종래에는 통전스프링을 보빈에 고정하기 위해 제2도와 같이 보빈(1)의 일측에 사각형상의 돌기(5)를 형성하고 상기 돌기(5)에 통전스프링(3)을 삽입하여 돌기에 끼워진 통전스프링이 돌기로부터 이탈되지 않게 하였다. 그러나 단지 보빈(1)에 형성된 돌기(5)에 통전스프링을 삽입하여 지지하는 종래의 장치는 제품의 조립시 또는 운반이나 이동시 통전스프링이 유동을 하여 전기적 단선을 초래할 우려가 많다.In the related art, in order to fix the energizing spring to the bobbin, a rectangular projection 5 is formed on one side of the bobbin 1 as shown in FIG. 2, and the energizing spring 3 is inserted into the projection 5 to insert the energizing spring. It did not escape from this process. However, the conventional apparatus for inserting and supporting the energizing spring into the protrusions 5 formed on the bobbin 1 is likely to cause electric disconnection due to the energizing spring flowing during assembly or transportation or movement of the product.
예를 들어 제품에 충격이 가해져 돌기(5)에 끼워진 통전스프링(3)이 유동을하는 경우 통전스프링의 끝단에 접속된 코일의 흔들림을 초래하여 단선이 되는 사례가 있고, 또한 베이스와의 조립시 코일단지부와 통전스프링 사이의 접촉이 이루어지지 않아 전자접촉기 본래의 기능인 스위치 기능이 상실될 우려가 많다.For example, when a shock is applied to the product and the energizing spring 3 inserted in the protrusion 5 flows, there is a case of breaking the coil connected to the end of the energizing spring, which causes disconnection, and also when assembling with the base. There is a possibility that the switch function, which is an original function of the magnetic contactor, may be lost because the contact between the coil stop and the energizing spring is not made.
본 고안은 통전스프링을 보빈의 일측에 확실히 고정시킬 수 있는 장치를 제고하기 위한 것인바, 이를 첨부된 도면 제3도를 참조하여 상세하게 설명한다.The present invention is to improve the device that can be securely fixed to the side of the bobbin of the bobbin, which will be described in detail with reference to FIG.
보빈(1)과 코일단자(2) 사이에 통전스프링(3)을 결합하는 것에 있어서, 보빈(1)의 일측에 원통형 보스(1a)를 형성하고 상기 원통형 보스에 통전스프링의 직경과 같은 직경을 가진 스프링 고정홈(1b)을 형성하여 통전스프링의 끝부분이 스프링 고정홈에 끼워져 고정되도록 한 것이다.In coupling the energizing spring 3 between the bobbin 1 and the coil terminal 2, a cylindrical boss 1a is formed on one side of the bobbin 1 and a diameter equal to the diameter of the energizing spring is formed on the cylindrical boss. By forming the spring fixing groove (1b) to the end of the energizing spring is inserted into the spring fixing groove to be fixed.
상기와 같이 된 본 고안은 통전스프링이 보빈에 형성된 돌기의 바깥측으로 끼워져 지지되는 종래의 장치와는 달리 통전스프링(3)의 끝부분이 보스(1a)에 형성된 스프링고정홈(1b)으로 끼워져 확실하게 고정되므로 제품의 조립시 또는 이동이나 운반시에도 통전스프링(3)과 보빈(1)의 결합부분에 유동이 발생할 우려가 없고, 이에따라 코일의 단선이나 접속 불량이 없어지게 되는 효과가 있다.The present invention as described above, unlike the conventional device in which the energized spring is fitted to the outer side of the projection formed on the bobbin and is supported, the end of the energized spring (3) is fitted into the spring fixing groove (1b) formed in the boss (1a) Therefore, there is no fear that flow may occur in the coupling portion of the energizing spring 3 and the bobbin 1 even when the product is assembled or moved or transported, thereby eliminating disconnection or poor connection of the coil.
