본 고안은 용접기의 2차측 케이블의 단자구조의 개선에 관한 것으로서, 좀 더 상세히는 용접변압기의 2차 코일측과 용접건 사이에서 용접전류를 전달하는 2차측 케이블의 단자의 접촉저항을 감소시킴으로써 단자부에서의 저항열에 의한 케이블의 소손을 방지하고 균일하고 안정된 용접전류가 흐를 수 있도록 한 새로운 구조의 케이블 단자에 관한 것이다.The present invention relates to the improvement of the terminal structure of the secondary cable of the welding machine, and more particularly, to the terminal part by reducing the contact resistance of the terminal of the secondary cable which transmits the welding current between the secondary coil side of the welding transformer and the welding gun. The present invention relates to a cable terminal of a new structure which prevents burnout of a cable due to resistance heat and allows a uniform and stable welding current to flow.
종래에 이러한 용접기의 2차 코일측과 용접건을 연결하기 위한 케이블로서 소위 '킥크레스식 케이블(kickless Cable)'과 단선왕복식 케이블이 알려져 있다. 킥크레스식 케이블이란 전기적으로 서로 절연된 2 경로의 도선을 한개의 호스 안에 넣는 수냉식 가요성 저리액턴스 케이블을 말하며, 단선왕복식 케이블이란 왕복 각 경로의 도선을 각각 한개의 호스 안에 묶어 넣은 수냉식 가요성 케이블을 말한다.(KS C 3615 참조). 제 1 도는 종래에 알려진 킥크레스 케이블을 예시하는 것으로서, 케이블(1)의 내부에 + 와 - 의 도선이 내장되고 그 사이에 냉각수가 흐르도록 구성되며, 용접건측단자(2)와 변압기측 단자(3)는 동일하게 절연판(4)을 사이에 두고 + 단자와 - 단자(5, 6)가 대향 구비된다. 또한, 제 2 도는 종래의 단선왕복식 케이블의 구조를 보여주는데, 케이블(1)의 내부에 + 또는 - 어느 한쪽의 도선이 내장되고 냉각수가 흐르도록 구성되며, 테이퍼진 형태의 용접건측 단자(7)와 플레이트 형태의 변압기측 단자(8)로 구성된다.Conventionally, so-called 'kickless cables' and single-wire reciprocating cables are known as cables for connecting the secondary coil side of the welder and the welding gun. Kickless cable is a water-cooled flexible low-reactance cable in which two wires are electrically insulated from each other in one hose, and a single-wire reciprocating cable is a water-cooled flexible cable in which each wire in each round-trip route is bundled in one hose. Refers to the cable (see KS C 3615). FIG. 1 illustrates a conventionally known kickless cable, in which wires of + and-are embedded in the cable 1 and a coolant flows therebetween, and the welding key terminal 2 and the transformer side terminal ( Similarly, 3) is provided with the + terminal and the-terminal 5 and 6 facing each other with the insulating plate 4 interposed therebetween. In addition, Figure 2 shows the structure of a conventional single-wire reciprocating cable, the + or-any one of the conductors are built into the cable (1) and configured to allow the coolant to flow, the welding key terminal 7 of the tapered form And a transformer side terminal 8 in the form of a plate.
종래의 이러한 용접 케이블은 대체로 소모품으로서 자주 교체하게 되는데, 용접케이블을 자주 교체해야 하는 중요한 이유 중의 하나는 케이블 단자의 접촉불량에 의한 접촉저항의 증대 및 이로 인한 단자부의 과열과 소손이라고 할 수 있다. 또한, 단자부의 접촉저항의 증가에 따라 안정되고 균일한 용접전류가 흐르지 못하여 용접의 품질이 저하되기도 한다는 문제점이 있었다. 특히, 최근에 자동차 조립라인과 같이, 공정이 자동화되고 단위시간 당 조립대수가 증가되는 상황에서 이러한 용접케이블의 소손 또는 파열에 의한 공정의 중단은 막대한 경제적, 시간적 손실을 초래하게 된다. 따라서 용접케이블도 단순한 소모품에서 나아가 내구성과 안정된 품질이 요구되기에 이르렀다.The conventional welding cable is often replaced as a consumable, and one of the important reasons for frequently replacing the welding cable is an increase in contact resistance due to poor contact of the cable terminal and thus overheating and burnout of the terminal portion. In addition, there is a problem that the quality of welding may be deteriorated because a stable and uniform welding current does not flow as the contact resistance of the terminal increases. In particular, in recent years, such as automobile assembly line, in the situation that the process is automated and the number of assembly per unit time is increased, the interruption of the process due to burnout or rupture of the welding cable will result in huge economic and time loss. Therefore, welding cables have come to demand durability and stable quality from simple consumables.
본 고안은 전술한 문제점에 착안하여 제안된 것으로서, 용접기의 2차측 케이블의 단자의 접촉저항을 감소시킴으로써 단자부에서의 저항열에 의한 케이블의 소손을 방지하고 균일하고 안정된 용접전류가 흐를 수 있는 새로운 케이블 단자를 제공하고자 하는 것이다.The present invention has been proposed in view of the above-described problems, and by reducing the contact resistance of the terminal of the cable of the secondary side of the welding machine, a new cable terminal which prevents burnout of the cable due to resistance heat in the terminal portion and allows a uniform and stable welding current to flow. Is to provide.
본 고안에 따르면, 용접기의 2차측 단자와 용접건 사이를 전기적으로 연결하는 용접케이블에 있어서, 상기 케이블 단자의 접점면에 금, 은 또는 주석을 피복한 것을 특징으로 하는 용접기용 케이블단자가 제공된다.According to the present invention, in the welding cable for electrically connecting between the secondary terminal of the welding machine and the welding gun, there is provided a cable terminal for a welding machine, characterized in that the contact surface of the cable terminal is coated with gold, silver or tin. .
이하에서 도면을 참조하여 본 고안의 바람직한 실시예를 설명한다. 제 3a 도와 제 3b 도는 본 고안에 따른 킥크레스 케이블의 단자부를 보여주는 도면으로서 도시된 바와 같이, 케이블 단자(5, 6)의 접점면(9)에 금, 은 또는 주석층(10)이 피복된다. 한편, 제4a도와 제4b도, 그리고 제5도는 각각 본 고안에 따른 단선왕복식 케이블의 변압기측 단자와 용접건측 단자(7)의 구조를 보여주는데, 역시 단자부의 접점면(11, 12), 즉, 전기적인 접촉부에도 금, 은 또는 주석층(13, 14)이 피복 도금된다. 또한, 제 6 도는 용접기의 2차 케이블로 사용되는 공냉식 점퍼케이블에 본 고안을 적용한 경우를 예시하는 것으로서, 케이블(1)의 단자(15)의 양측의 접접면(16)에도 금, 은 또는 주석층(17)을 피복한다.Hereinafter, with reference to the drawings will be described a preferred embodiment of the present invention. 3a and 3b show a gold, silver or tin layer 10 coated on the contact surface 9 of the cable terminals 5 and 6, as shown in the figure showing the terminal portion of the kickless cable according to the present invention. . On the other hand, Figures 4a, 4b and 5 respectively show the structure of the transformer-side terminal and the welding key side terminal 7 of the single-wire reciprocating cable according to the present invention, also the contact surface 11, 12, namely The electrical contacts are also plated with gold, silver or tin layers 13 and 14. In addition, FIG. 6 illustrates the case where the present invention is applied to an air-cooled jumper cable used as a secondary cable of a welding machine, and gold, silver, or tin may also be used on the contact surfaces 16 on both sides of the terminal 15 of the cable 1. Cover layer 17.
이러한 금, 은 또는 주석은 단자본체를 이루는 구리 또는 황동에 비해 도전율이 높은 금속으로서, 이들이 도금된 케이블 단자는 종래의 케이블에 비해 접점부에서 훨씬 우수한 도전율을 나타내며, 또한, 표면도 매끄럽게 마무리되므로 접촉불량이 감소되어 접촉저항을 최대한 감소시킬 수 있다. 이에 따라 저항열에 의한 케이블의 소손 및 이로 인한 누전이나 단락사고가 방지되고 케이블의 내구성이 향상된다. 또한, 용접전류가 균일하고 안정되게 흐르게 되므로 용접의 품질도 더욱 향상될 수 있다.Such gold, silver or tin is a metal having a higher conductivity than copper or brass constituting the terminal body, and the cable terminals coated with them have a much higher conductivity at the contact portion than the conventional cable, and also have a smooth finish on the surface. This can reduce the contact resistance as much as possible. Accordingly, the cable is prevented from being burned out due to the resistance heat, and the short circuit or short circuit caused by the resistance is prevented, and the durability of the cable is improved. In addition, since the welding current flows uniformly and stably, the quality of welding may be further improved.
