용접기용 단자연결부재{Subsidiary Structure for welding machine}Terminal connecting member for welding machine {Subsidiary Structure for welding machine}

본 고안은 용접기용 단자연결부재에 관한 것으로, 아크 용접기 혹은 플라즈마 절단기에 사용되는 출력단자에 용접봉으로부터 연결된 전선과 연결할 수 있도록 형성된 단자연결부재에 관한 것이다.The present invention relates to a terminal connecting member for a welding machine, and relates to a terminal connecting member formed to be connected to the wire connected from the electrode to the output terminal used in the arc welding machine or the plasma cutting machine.

일반적으로 용접(熔接,Welding)이란 2개의 금속을 용융상태 혹은 반용융상태에서 접합하는 것으로, 재료가 절약되고, 공정수가 절약되며, 접합효율이 좋고, 중량을 가볍게 할 수 있고, 보수하기 쉬우며, 설비비가 싸다는 장점이 있다.In general, welding is the joining of two metals in a molten or semi-melted state, which saves material, saves the number of processes, improves joining efficiency, reduces weight, and is easy to repair. In addition, the cost of equipment is low.

상기와 같은 용접기술은 전기용접과 가스용접으로 구분되며, 전기용접은 전기적으로 접합부를 가열하는 방법으로서 가열 방식에 따라 저항용접, 유도용접, 아크용접으로 나눌 수 있다.The welding technique as described above is divided into electric welding and gas welding, and the electric welding can be divided into resistance welding, induction welding, and arc welding according to a heating method as a method of electrically heating a joint.

아크용접(Arc Welding)의 원리는 용접봉의 철심의 주위에 화학약품과 용제를 피복한 것을 건조하여 전기회로에 모재와 전극 사이에 아크(Arc)를 발생시켜 약 6,000℃의 열에 의해 융해 시켜서 용착금속(Deposite Metal)을 만들어 두 모재를 접합시키는 방법이다.The principle of arc welding is to dry the coating of chemicals and solvents around the iron core of the welding rod, and generate arcs between the base material and the electrodes in the electric circuit, and melt them by heat of about 6,000 ℃. It is a method of joining two base materials by making (Deposite Metal).

플라즈마절단(Plazma Cutting)은 플라즈마의 고온을 이용하여 절단부를 용융(溶融, Melting)시켜서 절단하는 방법으로, 플라즈마란 양전하(이온), 음전하(전자)가 거의 같은 양으로 혼재하여 자유입자에 가까운 행세를 하면서 전기적으로 중성을 유지하고 있는 상태를 말하며 이러한 플라즈마를 생성시키기 위해서는 기체를 아크열로 가열하여 기체의 분자에서 전자가 떨어져 나오도록 하는 열 해리(解離) 현상을 일으키면 된다. 상기 열 해리 현상이 발생할 때 전자가 떨어져 나오면서 10000℃ 이상의 열 에너지를 발생 시키는데 이 열 에너지를 이용하여 절단부를 용융하는 것이다.Plasma cutting is a method of cutting by melting and cutting a cutting part by using a high temperature of plasma. Plasma is a method in which positive charges (ion) and negative charges (electrons) are mixed in almost the same amount and close to free particles. While maintaining the electrical neutral state and to generate such a plasma to heat the gas by arc heat to cause a thermal dissociation (lysis) phenomenon that electrons are released from the molecules of the gas. When the thermal dissociation phenomenon occurs, the electrons fall off to generate thermal energy of 10000 ° C. or more, and the thermal energy is used to melt the cut portion.

상기한 아크용접기와 플라즈마절단기(이하, 용접절단기로 약칭함.)는 교류전류를 인가받아서 내부에 정류회로와 고주파회로를 거치면서 높은 전압으로 변환되어 출력단자로 직류전류가 출력된다.The arc welding machine and the plasma cutting machine (hereinafter, abbreviated as welding cutting machine) are applied with alternating current and converted into high voltage while passing through a rectifying circuit and a high frequency circuit therein, so that the DC current is output to the output terminal.

종래의 용접절단기에는 도 1과 같이 출력단자에서 출력되는 전류를 출력부전선(20)을 통해서 용접부전선(10)으로 전달시키기 위해서 상기 출력부전선(20)의 끝단에 연결고리(21)를 만들고, 볼트로 결합한 단자연결부재(1)가 형성된다.In the conventional welding cutter, as shown in FIG. 1, a connection ring 21 is formed at the end of the output subsidiary wire 20 to transfer the current output from the output terminal to the welding subsidiary wire 10 through the output subsidiary wire 20. , The terminal connection member 1 coupled with a bolt is formed.

상기 단자연결부재(1)는 가운데 홀(2)이 형성되고, 케이스와 결합될 수 있는 몸체(5)가 형성되며, 상기 몸체(5)의 홀(2)에는 소켓(30)이 형성되는데, 상기 소켓(30)의 전단에 볼트와 같이 머리가 형성되고, 후단 외주연에는 결합너트(22)가 결합될 수 있도록 나사가 형성되며, 전면에서 일정깊이만큼 플러그홈(31)이 형성되고, 후면에는 일정깊이만큼 나사홈이 형성되어 있어 결합볼트(23)가 연결고리(21)과 함께 결합될 수 있도록 형성된다.The terminal connection member 1 has a center hole 2 formed therein, a body 5 which can be coupled with a case is formed, and a socket 30 is formed in the hole 2 of the body 5. A head is formed at the front end of the socket 30, such as a bolt, and a screw is formed at the rear outer periphery so that the coupling nut 22 can be coupled, and a plug groove 31 is formed at a predetermined depth from the front side, and the rear side. The screw groove is formed to a certain depth so that the coupling bolt 23 is formed to be coupled with the connecting ring (21).

상기 소켓(30)의 플러그홈(31)에는 플러그(40)가 삽입되는데, 상기 플러그(40)는 용접부전선(10)의 끝단과 연결되어 손잡이(45)로 둘러싸여서 형성된다.The plug 40 is inserted into the plug groove 31 of the socket 30, and the plug 40 is connected to the end of the welding wire 10 and is formed by being surrounded by the handle 45.

그러나, 종래의 단자연결부재는 케이스의 내부공간이 협소하므로 조립하기가 매우 불편하고, 외부의 용접부전선(10)도 플러그(40)에 조립하기가 힘든 불편함이 있었다.However, the conventional terminal connection member is very inconvenient to assemble since the inner space of the case is narrow, and the external weld subwire 10 is also inconveniently difficult to assemble to the plug 40.

상기한 문제점을 해결하기 위해서, 본 고안은 용접절단기의 케이스의 내/외부를 통해서 플러그와 소켓의 형식으로 결합되어 결합/분리가 간편하고, 출력부전선과 용접부전선이 용이하게 결합될 수 있도록 하여 용접절단기의 조립시간을 대폭 감소시킬 수 있는 단자연결부재를 제공함에 있다.In order to solve the above problems, the present invention is coupled in the form of a plug and a socket through the inside / outside of the case of the welding cutter is easy to combine / separate, welding the output subsidiary wire and the welding subsidiary wire to be easily coupled It is to provide a terminal connecting member that can greatly reduce the assembly time of the cutter.
