Description

알루미늄 전선{ALUMINIUM WIRE}Aluminum wire {ALUMINIUM WIRE}

본 발명은 알루미늄 전선에 관한 것으로서, 더욱 상세하게는 터미널에 압착되는 알루미늄 전선의 도체에 세레이션(serration)을 가공 형성함으로써 도체와 터미널의 고착율을 향상시키고, 터미널에 세레이션을 가공하는 것에 비해 가공비용을 줄일 수 있고, 세레이션을 형성한 도체를 모든 터미널에 접속할 수 있어 범용성을 확보할 수 있는 알루미늄 전선에 관한 것이다.
The present invention relates to an aluminum wire, and more particularly, by forming a serration on a conductor of an aluminum wire that is crimped to a terminal, thereby improving the fixing rate of the conductor and the terminal, and compared to processing the serration on the terminal. The present invention relates to an aluminum wire that can reduce the processing cost and can be connected to all terminals of a serrated conductor to ensure universality.

초음파 융착기는 초음파의 진동을 이용하여 융착 대상물을 융착하는 장비이다. 초음파 융착이란 초음파을 기계적인 에너지로 변환하여 융착 대상물간의 융착면에서 순간적인 마찰열을 발생시켜 용해 접착이 발생되도록 하는 공정을 의미한다.Ultrasonic welding machine is a device for fusion welding object using the vibration of the ultrasonic wave. Ultrasonic fusion refers to a process of converting ultrasonic waves into mechanical energy to generate instantaneous frictional heat at the fusion surface between fusion objects to cause dissolution adhesion.

특히 금속성 케이블의 단부에 터미널을 접합하기 위하여, 터미널을 케이블의 단부에 융착하는 경우 초음파 융착이 사용될 수 있다. 초음파 융착은 이종 금속간의 고상 확산을 유도하며, 융착대상 모재를 완전히 녹이지 않고 고체 상태에서 용접을 진행할 수 있는 이점이 있다.Ultrasonic welding may be used, in particular when welding the terminal to the end of the cable, in order to bond the terminal to the end of the metallic cable. Ultrasonic welding induces solid phase diffusion between dissimilar metals, and it is advantageous in that welding can be performed in a solid state without completely melting the base metal to be fused.

케이블 중에서도 저렴하고 무게가 가벼운 알루미늄 도체선을 구비한 알루미늄 케이블의 경우에는 알루미늄의 재료 특성상 용접성이 좋지 않고, 알루미늄 도체선의 표면에 산화피막이 존재하여 압착법 등의 접합공정을 적용할 수 없는 관계로 초음파 융착에 의한 접합이 사용될 수 있다.Among the cables, aluminum cables with inexpensive and light weight aluminum conductor wires do not have good weldability due to the material properties of aluminum, and because an oxide film exists on the surface of the aluminum conductor wires, it is impossible to apply a bonding process such as a crimping method. Fusion by fusion can be used.

알루미늄 케이블을 이종 금속 터미널 등에 융착의 방법으로 접합하는 경우, 초음파 융착기의 공구 혼과 케이블 도체선 간의 마찰에 의한 융착현상을 유도하여, 초음파 융착기의 공구 혼과 케이블 도체선 간의 늘어 붙음 또는 케이블 도체선의 손상을 유발하게 되어 작업효율을 저하시키고 불량품의 발생을 유발하게 된다.When joining an aluminum cable to a dissimilar metal terminal or the like by welding, the fusion phenomenon is induced by friction between the tool horn of the ultrasonic fusion machine and the cable conductor wire, and the stretching of the cable horn or the cable horn wire of the ultrasonic fusion machine is induced. It causes damage, lowers work efficiency and causes defective products.

그래서, 최근에는 알루미늄 케이블의 도체선과 접하는 터미널의 안착면에 세레이션(serration)이 형성되어 도체선과 터미널의 고착율을 향상시킨다.Thus, in recent years, a serration is formed on the seating surface of the terminal in contact with the conductor wire of the aluminum cable, thereby improving the fixing rate of the conductor wire and the terminal.

터미널의 세레이션에 대해서는 국내공개특허 제10-2011-0063404호에 제안된 바 있다.
Serration of the terminal has been proposed in Korean Patent Publication No. 10-2011-0063404.

기존 터미널은 알루미늄 케이블의 도체선과의 고착율을 높이기 위해 내측면에 세레이션을 별도로 가공하는데, 도체선에 따라 다양한 형상의 터미널 각각에 세레이션을 가공해야 하기 때문에, 세레이션 가공비가 많이 들고, 범용화가 어려운 문제점이 있다. 따라서, 이를 개선할 필요성이 요청된다.Conventional terminals separately process the serrations on the inner side to increase the fixation rate of the aluminum cable with the conductor wires, and the serrations are expensive and generalized because the serrations must be processed for each terminal of various shapes according to the conductor wires. There is a difficult problem. Therefore, there is a need to improve this.

본 발명은 상기와 같은 문제점들을 개선하기 위하여 안출된 것으로서, 터미널에 압착되는 알루미늄 전선의 도체 둘레면에 직접적으로 전기저항용접을 통해 세레이션(serration)을 가공 형성함으로써 도체와 일반적인 터미널의 고착율을 향상시킬 수 있고, 터미널에 세레이션을 가공하는 것에 비해 가공비용을 줄일 수 있으며, 세레이션을 형성한 도체를 모든 터미널에 접속할 수 있어 범용성을 확보하고자 하는 알루미늄 전선을 제공하는데 그 목적이 있다.
The present invention has been made to solve the above problems, by forming a serration through the electrical resistance welding directly on the conductor circumferential surface of the aluminum wire crimped to the terminal to improve the fixing rate of the conductor and the general terminal The purpose of the present invention is to provide an aluminum wire that can be improved, can reduce the processing cost compared to processing the serrations on the terminal, and the serration-formed conductor can be connected to all terminals to secure versatility.

본 발명에 따른 알루미늄 전선은: 절연재질의 피복, 및 상기 피복의 축방향을 따라 내부에 형성되고, 상기 피복의 외측으로 일부 노출되는 도체를 포함하고, 상기 도체에 세레이션(serration)부를 형성하는 것을 특징으로 한다.An aluminum wire according to the present invention comprises: a sheath of an insulating material and a conductor formed inside the axial direction of the sheath and partially exposed to the outside of the sheath, the serration being formed on the conductor. It is characterized by.

상기 도체는 대향하는 (+)전극과 (-)전극에 가압 접촉되어 통전시 일부 용융되고, 상기 (+)전극과 (-)전극은 용융된 상기 도체의 둘레면에 상기 세레이션부를 형성하기 위해 상기 도체의 둘레면에 불활성가스를 분사하도록 일측에 가스분사노즐을 구비함이 바람직하다.The conductor is partially melted when energized due to pressure contact with opposing (+) and (-) electrodes, and the (+) electrode and (-) electrode are formed to form the serration on the circumferential surface of the molten conductor. Preferably, a gas injection nozzle is provided at one side to inject an inert gas to the circumferential surface of the conductor.

상기 도체는 조(jaw)에 고정되고, 상기 조는 회전부재에 의해 회전됨이 바람직하다.
The conductor is fixed to a jaw, the jaw is preferably rotated by a rotating member.

이상에서 설명한 바와 같이, 본 발명에 따른 알루미늄 전선은 종래 기술과 달리 터미널에 압착되는 알루미늄 전선의 도체 둘레면에 직접적으로 전기저항용접을 통해 세레이션(serration)을 가공 형성함으로써 도체와 일반적인 터미널의 고착율을 향상시킬 수 있고, 터미널에 세레이션을 가공하는 것에 비해 가공비용을 줄일 수 있으며, 세레이션을 형성한 도체를 모든 터미널에 접속할 수 있어 범용성을 확보할 수 있다.
As described above, the aluminum wire according to the present invention, unlike the prior art, by bonding the conductor and the general terminal by forming a serration through electrical resistance welding directly on the conductor circumferential surface of the aluminum wire crimped to the terminal The ratio can be improved, the processing cost can be reduced compared to the processing of serrations on the terminal, and the serration-formed conductors can be connected to all terminals to ensure versatility.

In addition, the terms described below are defined in consideration of the functions of the present invention, which may vary depending on the intention or custom of the user, the operator. Therefore, definitions of these terms should be made based on the contents throughout this specification.

도 1은 본 발명의 일 실시예에 따른 알루미늄 전선에 세레이션부 가공을 위한 구성도이고, 도 2는 본 발명의 일 실시예에 따른 알루미늄 전선의 회전을 위한 구성도이며, 도 3은 본 발명의 일 실시예에 따른 알루미늄 전선과 터미널의 연결 상태를 보인 사시도이다.1 is a configuration diagram for processing a serration portion in an aluminum wire according to an embodiment of the present invention, Figure 2 is a configuration diagram for the rotation of the aluminum wire according to an embodiment of the present invention, Figure 3 is a present invention A perspective view showing a connection state of an aluminum wire and a terminal according to an embodiment of the present invention.

도 1 내지 도 3을 참조하면, 본 발명의 일 실시예에 따른 알루미늄 전선(10)은 피복(12) 및 도체(14)를 포함한다.1 to 3, an aluminum wire 10 according to an embodiment of the present invention includes a sheath 12 and a conductor 14.

피복(12)은 알루미늄 전선(10)의 외형을 형성하는 것으로서, 절연재질로 이루어진다.The sheath 12 forms an outer shape of the aluminum wire 10 and is made of an insulating material.

그리고, 도체(14)는 피복(12)의 축 방향을 따라 내부에 구비된다. 즉, 도체(14)는 둘레면에 피복(12)을 형성하여 절연된다. 이에 따라, 도체(14)는 축 방향을 따라 전기신호를 전송하게 된다.The conductor 14 is provided inside along the axial direction of the coating 12. That is, the conductor 14 is insulated by forming the coating 12 on the circumferential surface. Accordingly, the conductor 14 transmits an electric signal along the axial direction.

이때, 도체(14)는 알루미늄 재질로 이루어진다.At this time, the conductor 14 is made of aluminum.

또한, 도체(14)가 압착되는 터미널(2)은 통상 동(銅) 재질로 이루어진다. 즉, 도체(14)와 터미널(2)은 이종(異種) 금속이다. 특히, 도체(14)는 알루미늄 재질이기 때문에 공기와 접촉시 산화피막을 형성하게 되고, 이로 인해, 도체(14)와 터미널(2)의 고착율(固着率)이 저하된다. 고착율은 터미널(2)과 도체(14)의 결합강도를 의미한다. 터미널(2)은 다양하게 적용 가능하다.In addition, the terminal 2 to which the conductor 14 is crimped | bonded consists of copper materials normally. That is, the conductor 14 and the terminal 2 are dissimilar metals. In particular, since the conductor 14 is made of aluminum, an oxide film is formed upon contact with air, whereby the adhesion rate between the conductor 14 and the terminal 2 decreases. Fixation rate refers to the bonding strength between the terminal 2 and the conductor 14. The terminal 2 is variously applicable.

그래서, 도체(14)는 피복(12)의 축 방향을 따라 외측으로 노출되는 부위에 해당되는 둘레면에 세레이션부(100)를 가공 형성한다. 여기서, 세레이션부(100)는 세레이션(serration)을 포함하는 것으로서, 세레이션은 도체(14)의 둘레면에 패인 홈이나 나사산 또는 톱니 형상의 요철 등 다양하게 변형 가능하다.Therefore, the conductor 14 processes and forms the serration part 100 in the circumferential surface corresponding to the site | part exposed to the outer side along the axial direction of the coating | cover 12. FIG. Here, the serration part 100 includes a serration, and the serration may be variously modified, such as a groove, a thread, or a tooth-shaped unevenness formed in the circumferential surface of the conductor 14.

결과적으로, 도체(14)가 터미널(2)에 안착된 상태로 터미널(2)이 압착되면, 도체(14)와 터미널(2)은 세레이션부(100)에 의해 고착율이 증가하게 된다.As a result, when the terminal 2 is crimped with the conductor 14 seated on the terminal 2, the fixing rate of the conductor 14 and the terminal 2 is increased by the serration part 100.

여기서, 세레이션부(100)가 도체(14)에 가공 형성되기 때문에, 모든 터미널(2)은 최초 제작된 상태를 유지할 수 있어 세레이션부(100)의 가공 작업을 위한 제작비용을 줄일 수 있다. 그리고, 세레이션부(100)가 도체(14)에 형성됨에 따라, 도체(14)와 터미널(2)의 호환성이 향상된다. 특히, 터미널(2)은 별도의 세레이션이 가공되지 않는 초기 상태를 유지하게 된다(도 3참조).Here, since the serration part 100 is processed and formed in the conductor 14, all the terminals 2 can maintain the original manufacturing state, thereby reducing the manufacturing cost for the machining operation of the serration part 100. . And since the serration part 100 is formed in the conductor 14, the compatibility of the conductor 14 and the terminal 2 is improved. In particular, the terminal 2 is maintained in an initial state in which no separate serration is processed (see FIG. 3).

한편, 도체(14)는 다양한 방식에 의해 세레이션부(100)를 가공 형성할 수 있다. On the other hand, the conductor 14 can form and form the serration part 100 by various methods.

일례로, 도체(14)는 대향하는 (+)전극(22)과 (-)전극(24)에 가압 접촉된다. 그래서, (+)전극(22)과 (-)전극(24) 간에 일정한 용접전류가 통전되면, 도체(14)는 저항열에 의해 일부 용융된다.In one example, the conductor 14 is in pressure contact with the opposing (+) electrode 22 and the (-) electrode 24. Thus, when a constant welding current is applied between the positive electrode 22 and the negative electrode 24, the conductor 14 is partially melted by the heat of resistance.

이때, (+)전극(22)과 (-)전극(24) 간에 일정한 용접전류는 도체(14)가 600℃에서 660℃ 범위 내의 열을 받도록 제어됨이 바람직하다.At this time, it is preferable that the constant welding current between the (+) electrode 22 and the (-) electrode 24 is controlled so that the conductor 14 receives heat in the range of 600 ° C to 660 ° C.

도체(14)가 600℃미만의 열을 받게 되면, 알루미늄 재질인 도체(14)는 용융되지 않게 된다.When the conductor 14 receives heat of less than 600 ° C., the conductor 14 made of aluminum does not melt.

반대로, 도체(14)가 660℃를 초과한 열을 받게 되면, 알루미늄 재질인 도체(14)는 너무 용융되어 형태를 유지하지 못하게 된다.In contrast, when the conductor 14 receives heat exceeding 660 ° C., the conductor 14, which is made of aluminum, is too melted to maintain its shape.

특히, 알루미늄 전선(10)은 (+)전극(22)과 (-)전극(24)에 가압 접촉된 상태에서 작업대(40)에 지지됨이 바람직하다. 이때, 알루미늄 전선(10)은 작업대(40)에 단순히 놓여질 수도 있고, 작업대(40)에 위치 고정되게 설치될 수도 있다.In particular, the aluminum wire 10 is preferably supported on the work table 40 in a state of being in pressure contact with the (+) electrode 22 and the (-) electrode 24. In this case, the aluminum wire 10 may be simply placed on the work table 40 or may be installed to be fixed to the work table 40.

또한, 도체(14)의 특정 둘레면이 (+)전극(22)과 (-)전극(24) 간에 일정한 용접전류로 인해 일부 용융된 상태에서, 도체(14)의 해당 부위는 쉽게 세레이션부(100)를 형성하게 된다.Further, in a state in which a specific circumferential surface of the conductor 14 is partially melted due to a constant welding current between the (+) electrode 22 and the (-) electrode 24, the corresponding portion of the conductor 14 is easily serrated. To form (100).

예로, (+)전극(22)과 (-)전극(24)은 용융된 도체(14)의 둘레면에 세레이션부(100)를 형성하기 위해 도체(14)의 둘레면에 불활성가스를 분사하도록 일측에 가스분사노즐(30)을 구비한다.For example, the positive electrode 22 and the negative electrode 24 inject an inert gas to the peripheral surface of the conductor 14 to form a serration portion 100 on the peripheral surface of the molten conductor 14. The gas injection nozzle 30 is provided at one side thereof.

즉, 가스분사노즐(30)이 불활성가스를 도체(14)의 둘레면에 일정한 압력으로 조사하게 되면, 도체(14)의 둘레면은 홈이 파지면서 자연적으로 세레이션부(100)를 형성하게 된다.That is, when the gas injection nozzle 30 irradiates an inert gas to the circumferential surface of the conductor 14 at a constant pressure, the circumferential surface of the conductor 14 forms a serration part 100 naturally while the groove is dug. do.

이때, (+)전극(22)과 (-)전극(24) 및 가스분사노즐(30)은 작업대(40)에 지지되도록 설치됨이 바람직하다.At this time, the (+) electrode 22 and the (-) electrode 24 and the gas injection nozzle 30 is preferably installed to be supported on the work table (40).

한편, 도체(14)의 둘레면 중 일부만이 가스분사노즐(30)과 대향할 경우, 세레이션부(100)는 도체(14)의 둘레면 중 일부분에만 형성된다.On the other hand, when only a part of the circumferential surface of the conductor 14 faces the gas injection nozzle 30, the serration part 100 is formed only on a part of the circumferential surface of the conductor 14.

그래서, 알루미늄 전선(10)은 회전됨이 바람직하다. 이는, 세레이션부(100)가 도체(14)의 원주 방향으로 고르게 가공 형성되도록 하기 위함이다.Thus, the aluminum wire 10 is preferably rotated. This is to allow the serration part 100 to be uniformly formed in the circumferential direction of the conductor 14.

결과적으로, 도체(14)는 외부 조작에 의해 자동적으로 벌어지거나 좁혀지는 조(jaw,52)에 고정되고, 조(52)는 회전부재(54)에 의해 회전된다. 즉, 조(52)는 한 쌍으로 이루어져 다양한 방식에 의해 좁혀지거나 멀어지게 된다. 그리고, 회전부재(54)는 구동모터로 함이 바람직하다. As a result, the conductor 14 is fixed to a jaw 52 which is automatically opened or narrowed by external operation, and the jaw 52 is rotated by the rotating member 54. That is, the jaw 52 is formed in a pair to be narrowed or moved away in various ways. The rotating member 54 is preferably a drive motor.

이에 따라, 조(52)는 도체(14)를 물고 있는 상태로 회전부재(54)에 의해 회전된다. 그래서, 세레이션부(100)는 가스분사노즐(30)의 불황성가스 분사로 인해 도체(14)의 원주방향을 따라 고르게 형성된다. 이때, 도체(14)는 축 방향을 따라 세레이션부(100)를 가공 형성하도록 이동 가능하게 구비됨이 바람직하다. 도시하지는 않았지만, 알루미늄 전선(10)이 축 방향을 따라 이동 가능하도록, 조(52)를 구비한 회전부재(54)가 알루미늄 전선(10)의 축 방향을 따라 전후진 가능하도록 작업대(40)에 설치됨이 바람직하다.As a result, the jaw 52 is rotated by the rotating member 54 while the conductor 14 is being bitten. Thus, the serration part 100 is formed evenly along the circumferential direction of the conductor 14 due to the inert gas injection of the gas injection nozzle 30. At this time, the conductor 14 is preferably provided to be movable to form the serration part 100 along the axial direction. Although not shown, the rotary member 54 with the jaw 52 is movable on the work table 40 so that the aluminum wire 10 can move along the axial direction so that the aluminum wire 10 can move back and forth along the axial direction of the aluminum wire 10. It is preferred to be installed.
