Description

미세용접기의 용접전극 { a welding terminal for a welding machine }Welding electrode of micro welding machine {a welding terminal for a welding machine}

본 고안은 작은 직경의 전기코일 등의 도전성 금속소선을 전기접속단자 등에 간편하게 용접할 수 있도록 하는 미세용접기의 용접전극에 관한 것으로, 더 자세하게는 절연피막 유무에 관계없이 도전성 금속소선을 보다 안정적으로 용접할 수 있도록 한 것에 관한 것이다.The present invention relates to a welding electrode of a micro-welding machine for easily welding conductive metal wires, such as small diameter electric coils, to electrical connection terminals, and more particularly, to more stably weld conductive metal wires with or without insulation coating. It's about making it possible.

종래에 있어서 전기코일 등의 도전성 금속소선을 전기저항열을 이용하여 전기접속단자 등에 용접할 수 있도록 하는 미세용접기의 용접전극은 도 4와 같이 한 쌍의 전극판(41)(42)을 일정거리 이격시킨 것이 주로 사용되었다.Conventionally, a welding electrode of a micro welder for welding a conductive metal wire such as an electric coil to an electrical connection terminal by using electric resistance heat, has a predetermined distance between the pair of electrode plates 41 and 42 as shown in FIG. The spaced ones were mainly used.

상기 종래의 용접전극(40)은 전기접속단자(30)의 상단에 금속소선(20)을 올려놓은 다음 금속소선(20)의 용접할 부위를 용접전극(40)의 각 전극판 하단부로 가압하게 되면 일 전극판(41)-금속소선(20)-타 전극판(42)으로 전류가 흐르게 되고, 그에 따라 각 전극판(41)(42)과 금속소선(20)의 접촉부위에 전기저항열이 발생하게 되어 금속소선(20)이 전기접속단자(30)에 융착되는 것으로, 이와 같은 종래의 용접전극(40)은 금속소선(20)을 통해 전류가 흐르게 되므로 용접상태가 비교적 양호하게 되지만 금속소선(20)의 표면에 절연피막이 형성되어 있는 경우에는 사용할 수 없는 문제가 있었다.The conventional welding electrode 40 puts the metal wire 20 on the upper end of the electrical connection terminal 30 to press the portion to be welded on the metal wire 20 to the lower end of each electrode plate of the welding electrode 40. When the current flows to the one electrode plate 41, the metal element wire 20, and the other electrode plate 42, electric resistance heat is generated at the contact portion between each of the electrode plates 41 and 42 and the metal element wire 20. This causes the metal wire 20 to be fused to the electrical connection terminal 30, such that the conventional welding electrode 40 is a relatively good welding state because the current flows through the metal wire 20, but the metal When the insulating film was formed in the surface of the element wire 20, there existed a problem which cannot be used.

즉, 주로 전기전도성이 뛰어난 구리재질로 제작되는 전기코일 등의 금속소선은 표면부식 및 누전 등을 방지하기 위해서 표면에 절연피막을 형성하는 예가 많은 바, 전술한 종래의 용접전극(40)을 절연피막이 형성된 금속소선에 접촉시키게 되면 양 전극판(41)(42) 사이에 전류가 흐르지 않게 되기 때문에 전기저항열이 발생하지 않게 되어 용접을 할 수 없게 된다.That is, metal wires such as electric coils mainly made of copper material having excellent electrical conductivity often form an insulating film on the surface to prevent surface corrosion and short-circuit, and thus, insulate the conventional welding electrode 40 described above. When the film is brought into contact with the metal element wire formed thereon, no electric current flows between the two electrode plates 41 and 42, so that no electric resistance heat is generated and welding cannot be performed.

한편 도 5에 도시한 종래의 다른 용접전극(50)은 전체 형상을 U자형으로 구성한 것으로, 이 다른 용접전극(50)은 도전성 금속소선(20)에 접촉시키지 않더라도전기저항열을 발생시킬 수 있게 되므로 절연피막(21)이 형성되지 않은 금속소선(20)은 물론 절연피막(21)이 형성된 금속소선(20)도 용접할 수 있게 되는 것이지만 금속소선(20)에 접촉된 상태에도 고저항체인 용접전극(50)의 하단 중심부에 계속적으로 전류가 흐르게 되므로 온도제어가 어렵게 되고 용접상태가 나쁘게 되는 문제가 있었다.Meanwhile, another conventional welding electrode 50 shown in FIG. 5 has a U-shape in overall shape, and the other welding electrode 50 can generate electric resistance heat even without contacting the conductive metal wire 20. Therefore, it is possible to weld not only the metal wire 20 without the insulating film 21 formed thereon but also the metal wire 20 with the insulating film 21 formed thereon, but the welding is a high resistance element even when the metal wire 20 is in contact with the metal wire 20. Since the current continuously flows through the lower center of the electrode 50, the temperature control becomes difficult and the welding state becomes bad.

본 고안은 상기와 같은 종래의 실정을 감안하여 안출한 것이며, 그 목적이 절연피막의 유무와 관계없이 도전성 금속소선을 안정적으로 용접할 수 있도록 하는 미세용접기의 용접전극을 제공하는 데에 있는 것이다.The present invention has been devised in view of the above-described conventional situation, and an object thereof is to provide a welding electrode of a microwelder which can stably weld conductive metal wires with or without an insulating coating.

즉, 도 1에서 도 3까지에는 본 고안의 한 실시예가 도시되어 있는 바, 본 고안의 용접전극(10)은 일정거리를 이격시킨 한 쌍의 전극판(11)(12)의 사이에 절연접착층(13)을 마련하고, 양 전극판(11)(12) 내측 하단면에 접촉부(14)를 마련하여서 되는 것이다.That is, one embodiment of the present invention is shown in Figures 1 to 3, the welding electrode 10 of the present invention is an insulating adhesive layer between a pair of electrode plates 11, 12 spaced a predetermined distance (13) is provided, and the contact part 14 is provided in the lower end surface inside both electrode plates 11 and 12.

도시된 실시예는 접촉부(14)의 상부에 일정길이의 공간부(15)를 마련하고, 공간부(15)와 절연접착층(13)의 사이에 열차단절연부재(16)를 설치한 형태를 갖는다.In the illustrated embodiment, a space portion 15 having a predetermined length is provided on an upper portion of the contact portion 14, and a heat shield insulation member 16 is disposed between the space portion 15 and the insulating adhesive layer 13. Have

상기와 같이 구성된 본 고안에 있어서는 금속소선(20) 등의 전도체에 양 전극판(11)(12)을 접촉시키지 않더라도 접촉부(14)를 통해 전류가 흐르게 되어 전기저항열을 발생시킬 수 있게 되므로 절연피막(21)이 없는 금속소선(20)은 물론 절연피막(21)이 있는 금속소선(20)도 안정적으로 용접할 수 있게 되는 것으로, 절연피막(21)이 있는 금속소선(20)을 전기접속단자(30)에 용접하는 경우 전기접속단자(30)의 상단에 금속소선(20)을 올려놓은 다음 금속소선(20)의 용접할 부위를 용접전극(10)의 각 전극판(11)(12) 하단부로 가압하게 되면 접촉부(14)를 통해 전류가 흘러서 접촉부(14)를 중심으로 발열이 진행되는 각 전극판(11)(12)의 하단부를 통해 1차적으로 금속소선(20)의 절연피막(21)을 녹일 수 있게 되며, 절연피막(21)이 제거된 후에는 전기저항값이 높은 접촉부(13)보다는 전기저항값이 낮은 재질의 금속소선(20)을 통해 전류가 흐르면서 금속소선(20)을 전기접속단자(30)에 안정적으로 융착시킬 수 있게 된다.In the present invention configured as described above, even though the positive electrode plates 11 and 12 do not come into contact with a conductor such as the metal wire 20, the current flows through the contact portion 14, so that electric resistance heat can be generated. It is possible to stably weld the metal wire 20 with the insulating film 21 as well as the metal wire 20 without the coating 21, and electrically connect the metal wire 20 with the insulating film 21. In the case of welding to the terminal 30, the metal wire 20 is placed on the upper end of the electrical connection terminal 30, and then the portion to be welded on the metal wire 20 is welded to each electrode plate 11, 12 of the electrode 10. When pressurized to the lower end, an insulating film of the metal element 20 is primarily through the lower end of each of the electrode plates 11 and 12 in which current flows through the contact part 14 to generate heat around the contact part 14. 21 can be melted, and after the insulating film 21 is removed, the electrical resistance value is higher than that of the contact portion 13. As the current flows through the metal element wire 20 having a low electric resistance value, the metal element wire 20 can be stably fused to the electrical connection terminal 30.
