전기 자동차용 부스바의 고주파 브레이징 장치{The high frequency brazing device for BUS BAR of electric vehicle}The high frequency brazing device for BUS BAR of electric vehicle}

본 발명은 전기 자동차용 부스바의 접합 장치에 관한 것으로서, 더욱 상세하게는 제1부스바(1)와 제2부스바(2)를 용가재판(3)을 매개체로 서로 접합하되, 고주파 브레이징 접합 기술을 통해 전기 전도중 전기적 손실을 최소화할 수 있는 전기 자동차용 부스바의 고주파 브레이징 장치에 관한 것이다.The present invention relates to a bonding device for busbars for electric vehicles, and more particularly, to bond a first busbar (1) and a second busbar (2) to each other with a filler plate (3) as a medium, and high-frequency brazing bonding It relates to a high-frequency brazing device for an electric vehicle busbar capable of minimizing electrical loss during electrical conduction through technology.

본 발명이 속하는 부스바(BUS BAR)는 전기적 에너지를 전달하기 위한 전도체를 일컫는다. 일반적인 형상은 이음매가 없는 막대 형상이나, 근자에는 절곡부가 많고, 이음매가 있는 형상으로 만들어지고 있다.A bus bar to which the present invention belongs refers to a conductor for transmitting electrical energy. The general shape is a seamless bar shape, but there are many bent parts in the root, and it is made into a shape with a joint.

전기 자동차의 배터리에 전기를 공급하기 위한 부스바는 다른 부품과 조화를 이루면서 간섭 없이 장착되어야 하는바, 이 과정에서 부스바의 절곡과 이음매가 필연적으로 발생되고 있다.A busbar for supplying electricity to the battery of an electric vehicle must be mounted without interference while harmonizing with other parts. In this process, bending and seams of the busbar inevitably occur.

종래에는 부스바의 이음매를 접합하고자 금속간 접합에 광범위하게 사용되는 전기저항용접을 사용하였다. 전기저항용접은 용접 부위에 전류를 가하여 접합 부위를 가열시키고, 동시에 큰 압력을 가함으로써, 금속을 접합시키는 방식이며, 스팟 용접이 대표적인 사례이다.Conventionally, electric resistance welding, which is widely used for metal-to-metal bonding, has been used to join the joints of busbars. Electric resistance welding is a method of joining metals by applying a current to the welded portion to heat the joined portion and applying a large pressure at the same time, and spot welding is a representative example.

문제는 스팟 용접을 통해 만들어진 부스바의 이음매에 강한 전류 입력시 스팟 용접 부위가 약해지면서 단락 현상이 발생되어 전원 공급이 일시 단절되는 등 인명 사고와 직결될 수 있는 문제점이 발생되고 있다.The problem is that when a strong current is input to the joint of the busbar made through spot welding, the spot welding part becomes weak and a short circuit occurs, causing a problem that can be directly connected to human accidents such as temporary disconnection of power supply.

한편, 단락의 문제점을 해결하고자 리벳 방식으로 부스바의 이음매를 연결하였으나, 이음매에 리벳과 같은 물리적인 기계 요소가 부가되면서 필연적으로 저항값이 상승되어 전류의 손실이 발생하는바, 부스바 접합 관련 산업 분야에서는 전기적 손실을 최소화할 수 있는 더욱 효과적인 이음매 접합 방법이 절실히 요구되는 실정이다.On the other hand, in order to solve the short circuit problem, the busbar joints are connected by a rivet method, but as physical mechanical elements such as rivets are added to the joints, the resistance value inevitably rises, resulting in current loss. In the industrial field, there is an urgent need for a more effective joint bonding method capable of minimizing electrical loss.
