Description

주석도금 알루미늄 연선{Tin Plated Aluminium Wire}Tin Plated Aluminum Wire

본 발명은 주석도금 알루미늄 연선에 관한 것으로, 더욱 상세하게는 주요 전원용 전선이나 음향기기용 케이블 등에 사용되는 연선에 관한 것이다.The present invention relates to a tin-plated aluminum stranded wire, and more particularly, to a stranded wire used for a main power cable, a cable for an acoustic device, and the like.

일반적으로 연선(twisted pair wire)은 각각 절연된 지름이 작은 두 줄의 동선을 서로 꼬아서 1조의 도선으로 피복 처리한 것이다. 평행형의 도선에 비해 감쇄와 전기 잡음의 영향을 억제한다. 원래 구내 전화선의 배선이나 모뎀의 회로 등에 사용되었는데, 가격이 저렴하고 무게가 가벼우며 포설이 쉬워 구내 정보 통신망(LAN)의 전송 매체로도 사용되고 있다. 연선을 사용하는 LAN의 매체 규격으로는 IEEE 802.3의 10 BASE-T나 IEEE 802.5의 토큰 링 등이 있다. 최근에는 전송 속도 100Mbps의 광섬유 분산 데이터 인터페이스(FDDI)나 고속 이더넷에 연선을 전송 매체로 사용하여 실현하는 제품도 출시되고 있다. 연선은 차폐 연선(STP)과 비차폐 연선(UTP)으로 구분된다. 차폐 연선은 실드막을 풀어 둔 연선이라고 불리며 STP(Shielded Twisted Pair)라고도 한다. 신호 간섭이 많은 공장이나 야외, 또는 빠른 통신 속도가 필요한 곳에 쓰인다. 유럽에서는 STP가 주로 쓰이며 UTP는 거의 보급되어 있지 않다. 비차폐 연선은 실드 막을 풀지 않은 연선이라고 불리며 UTP(Unshielded Twisted Pair)라고도 한다. 이것은 전화선이나 인터넷 등에 쓰인다. 처리가 간단하고 값이 싸서 빠른 전송이 필요 없는 인터넷의 랜 용도에 표준으로 쓰이고 있다.In general, twisted pair wire is a pair of conductors twisted together by twisting two copper wires each having a smaller diameter. It suppresses the effects of attenuation and electrical noise compared to parallel conductors. Originally used for wiring of telephone lines and modems in the premises, it is also used as a transmission medium for premises LANs because of its low cost, light weight, and easy installation. Media standards of LANs using twisted pairs include IEEE 802.3 10BASE-T and IEEE 802.5 token rings. Recently, products that use a twisted pair cable as a transmission medium for optical fiber distributed data interface (FDDI) or high-speed Ethernet with a transmission speed of 100 Mbps have been released. Twisted pairs are divided into shielded twisted pair (STP) and unshielded twisted pair (UTP). The shielded twisted pair is called a twisted pair with the shield film loosened, and is also called a shielded twisted pair (STP). It is used in factories or outdoor areas where signal interference is high, or where high communication speed is required. STP is mainly used in Europe, and UTP is rarely used. Unshielded twisted pair is called unshielded twisted pair and is also known as Unshielded Twisted Pair (UTP). This is used for telephone lines or the Internet. It is used as a standard for LAN use of the Internet because it is simple and inexpensive and does not require fast transmission.

종래의 연선으로 구리(Cu) 또는 알루미늄(Al)이 적용되었지만, 구리나 알루미늄은 부식에 약해 쉽게 표면이 산화된다. 더욱이 연선을 차량의 각종 배선용으로 사용할 경우에 배기가스 등에 의하여 화학적인 산화가 발생하게 되고, 이로 인하여 스파크의 발생 위험이 높아지게 된다. 따라서 차량에 적용되는 연선은 전원이나 신호를 정상적으로 전달하지 못하는 문제가 있었다. 또한 구리로 된 동선은 전기전도도는 좋지만 비중이 높아 중량이 크고 상대적인 가격이 높아 운반비 및 제품의 단가가 높아지는 문제도 있었다.Although copper (Cu) or aluminum (Al) has been applied as a conventional stranded wire, copper or aluminum is susceptible to corrosion and the surface is easily oxidized. Moreover, when the stranded wire is used for various wirings of the vehicle, chemical oxidation occurs due to the exhaust gas, which increases the risk of sparks. Therefore, the twisted pair applied to the vehicle has a problem that does not normally transmit power or signals. In addition, copper copper wire has good electrical conductivity, but has a high specific gravity, so that the weight and the relative price are high, resulting in increased transportation costs and product costs.

본 발명은 상기 문제점을 해결하기 위하여, 알루미늄(Al)에 주석을 용융도금 처리하여 전기적인 특성은 높으면서 저렴하고 경량화한 연선을 제공하기 위한 것이 목적이다.SUMMARY OF THE INVENTION In order to solve the above problems, an object of the present invention is to provide a stranded wire that is inexpensive and light in weight while having a high electrical property by hot-plating tin on aluminum (Al).

또한, 본 발명은 구리에 주석이 용융도금 처리된 단자를 연선의 단부에 결합하기 위한 것이 다른 목적이다. In addition, another object of the present invention is to couple a terminal in which tin is copper plated with copper to an end of a stranded wire.

본 발명은 상기 목적을 달성하기 위하여, 복수의 선을 하나의 도선으로 꼬아 만든 알루미늄(Al) 재질의 연선에 있어서, 상기 알루미늄 재질의 연선 두께에 3/1,000 내지 5/1,000 비율의 두께로 주석을 도금조에서 용융도금 처리하고, 상기 연선의 단부에 전기적인 연결을 위하여 구리(Cu) 재질의 단자를 압착 결합하며, 상기 구리(Cu) 재질의 단자 두께에 3/1,000 내지 5/1,000 비율의 두께로 주석을 도금조에서 용융도금 처리하여 양호한 전기적인 특성 및 경량화한 주석도금 알루미늄 연선을 제공한 것이 특징이다.In the present invention, in order to achieve the above object, in the stranded wire made of aluminum (Al) made by twisting a plurality of wires into a single conductive wire, tin is formed at a thickness of 3 / 1,000 to 5 / 1,000 in the thickness of the stranded wire of the aluminum material. Hot-dip galvanizing in a plating bath, press-bonding the copper (Cu) terminal for electrical connection to the end of the stranded wire, the thickness of the copper (Cu) terminal thickness of 3 / 1,000 to 5 / 1,000 ratio Furnace tin is hot-dipped in a plating bath to provide good electrical properties and light weight tin-plated aluminum stranded wire.

본 발명은 상기 해결수단에 의하여, 전원용 전선이나 음향기기용 케이블로 주석이 용융도금 처리된 연선을 적용하여 부식방지 및 양호한 전기전도도와 더불어 연선의 경량화와 제작단가의 절감을 구현한 효과가 있다.The present invention has the effect of realizing the weight reduction and cost reduction of the stranded wire with corrosion prevention and good electrical conductivity by applying a twisted wire is tin-plated with a power wire or a cable for sound equipment by the above solution.

이하, 첨부된 도면을 참조하여 본 발명의 주석도금 알루미늄 연선에 관하여 상세하게 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the tin-plated aluminum stranded wire of the present invention.

도 1은 본 발명의 주석도금 알루미늄 연선을 나타낸 도면이고, 도 2는 연선에 단자가 결합된 상태를 나타낸 도면이다.1 is a view showing a tin-plated aluminum stranded wire of the present invention, Figure 2 is a view showing a state in which the terminal is coupled to the stranded wire.

먼저, 본 발명의 스파크 방지용 연선은 알루미늄(Al)에 일정 두께로 주석(Sn)이 용융도금 처리되어 부식에 강하고 가벼우며 제조단가를 최소화한 것이다.First, the strand for preventing sparks of the present invention is a tin (Sn) is hot-dipped in aluminum (Al) to a certain thickness to resist corrosion, light and minimize the manufacturing cost.

연선(10)은 복수 가닥의 알루미늄 선을 꼬아 하나의 도선으로 제조되거나, 제조된 여러 가닥의 도선을 다시 꼬아 더 굵은 도선으로 제조된다. 이는 연선의 용도에 따라 그 적용범위가 달라질 수 있기 때문이다. 즉 전원용 전선이나 음향기기용 케이블에 달라질 수 있고, 실내용이나 실외용 또는 차량용 등에 따라 적용이 달라질 수 있기 때문이다.The stranded wire 10 is made of a single wire by twisting a plurality of aluminum wires, or is made of a thicker wire by twisting the wires of several strands produced again. This is because the application range may vary depending on the use of the stranded wire. That is, because it may vary in power wires or cables for sound equipment, and application may vary depending on indoor use, outdoor use, or vehicle use.

상기 알루미늄 재질의 연선(10)에는 주석(12)이 도금된다. 더욱이 이미 꼬아진 알루미늄선(11)에 주석(12)을 도금하거나 알루미늄선(11)을 꼬기 전에 주석(12)을 도금할 수 있다. 알루미늄선(11)은 도금조에서 도금이 이루어지고, 알루미늄선(11)을 도금할 때에 전기로 도금할 수도 있지만, 바람직하게는 용융도금으로 처리하는 것이 좋다. 즉 알루미늄선(11)이 녹으면서 표면에 주석(12)이 도금되도록 하는 것이 좋다. 이때 알루미늄선(11)의 외주연에 도금되는 주석(12)은 알루미늄선(11)의 두께에 대하여 대략 3/1,000 내지 5/1,000 비율의 두께로 도금되는 것이 좋다. 주석(12)의 도금 두께가 얇으면 쉽게 박리되므로 두꺼울수록 좋다.Tin 12 is plated on the stranded wire 10 made of aluminum. Furthermore, the tin 12 may be plated on the already twisted aluminum wire 11 or the tin 12 may be plated before the aluminum wire 11 is twisted. The aluminum wire 11 is plated in a plating bath and can be plated with electricity when the aluminum wire 11 is plated. Preferably, the aluminum wire 11 is treated by hot dip plating. That is, it is preferable that the tin 12 is plated on the surface while the aluminum wire 11 is melted. At this time, the tin 12 to be plated on the outer periphery of the aluminum wire 11 is preferably plated in a thickness of approximately 3 / 1,000 to 5 / 1,000 ratio with respect to the thickness of the aluminum wire (11). The thinner the plating thickness of the tin 12, the easier it is to peel off.

그리고 상기 연선(10)의 단부에는 전기적인 연결을 위하여 구리(Cu) 재질의 단자(20)가 압착 결합된다. 단자(20)는 구리편(21) 중앙에 결합공(23)이 형성된 것으로 연선(10)의 단부와 압착 결합되는 부분과 단자대에 결합되는 부분으로 구분된다. 구리편(21)은 도금조에서 도금이 이루어지고, 구리편(21)을 도금할 때에 전기로 도금할 수도 있지만, 바람직하게는 용융도금으로 처리하는 것이 좋다. 즉 구리편(21)이 녹으면서 표면에 주석(22)이 도금되도록 하는 것이 좋다. 이때 구리편(21)의 외주연에 도금되는 주석(22)은 구리편(21)의 두께에 대하여 대략 3/1,000 내지 5/1,000 비율의 두께로 도금되는 것이 좋다. 주석(22)의 도금 두께가 얇으면 쉽게 박리되므로 두꺼울수록 좋다.In addition, the terminal 20 of the copper (Cu) material is pressed to the end of the stranded wire 10 for electrical connection. The terminal 20 is formed with a coupling hole 23 in the center of the copper piece 21, and is divided into a portion that is press-bonded to the end of the strand 10 and a portion that is coupled to the terminal block. Although the copper piece 21 is plated in a plating bath and can be plated with electricity at the time of plating the copper piece 21, it is preferable to process by hot-dip plating. That is, it is preferable that the tin 22 is plated on the surface while the copper piece 21 is melted. At this time, the tin 22 plated on the outer circumference of the copper piece 21 is preferably plated in a thickness of approximately 3 / 1,000 to 5 / 1,000 ratio with respect to the thickness of the copper piece 21. The thinner the plating thickness of the tin 22, the easier it is to peel off.

한편, 도 3에서, 상기 연선(10)의 외주연에는 합성수지나 고무 재질의 피복(30)을 씌우거나 끼워 외부로부터 가해지는 각종 전자파를 차폐시키거나 배선된 주변의 선들로부터 누화를 방지할 수 있도록 하는 것이 좋다.Meanwhile, in FIG. 3, the outer periphery of the stranded wire 10 is covered with or sandwiched with a synthetic resin or rubber sheath 30 so as to shield various electromagnetic waves applied from the outside or prevent crosstalk from surrounding wires. Good to do.

도 4는 단자대(40)에 연선(10)의 단자(20)를 고정부재(41)로 각각 연결한 상태이다. 여기서 알루미늄선(11)에 주석(12)이 용융도금된 본 발명의 스파크 방지용 연선의 물성은 구리선과 거의 동일 내지는 유사한 전기적인 특성을 나타내었다. 이에 대한 플렉시블 케이블의 온도상승시험을 수행한 결과, 습도 40%와 온도 22℃의 시험환경에서 차량에서 요구하는 60A-DC24V를 인가하였을 때에 단자대(40)의 인입부와 인출부 사이의 온도차가 기준치 50K에서 최대상승치는 2.1~6.3K 이내의 온도차를 나타내었다. 그리고 대략 60Ω 이내의 안전한 저항값을 나타내었다.4 is a state in which the terminals 20 of the stranded wire 10 are connected to the terminal block 40 with the fixing members 41, respectively. Here, the physical properties of the spark-resistant stranded wire of the present invention, in which tin 12 is hot-plated on the aluminum wire 11, exhibited almost the same or similar electrical properties as the copper wire. As a result of the temperature rise test of the flexible cable, when the 60A-DC24V required by the vehicle is applied in a test environment of 40% humidity and 22 ° C, the temperature difference between the inlet and the outlet of the terminal block 40 is the reference value. The maximum rise at 50K showed a temperature difference within 2.1 ~ 6.3K. In addition, it showed a safe resistance value within approximately 60 mA.

따라서 본 발명의 연선이 차량의 배선이나 음향기기의 케이블로 적용된 경우에 구리선과 동일한 안전성을 나타내었다.Therefore, when the stranded wire of the present invention is applied to a vehicle wiring or a cable of an acoustic device, the same safety as that of the copper wire is shown.

본 발명의 스파크 방지용 연선은 구리선과 동일한 전기적인 특성을 나타내면서 부식성에 강하고 경량이며 저가로 구현한 장점이 있다.Spark-resistant stranded wire of the present invention exhibits the same electrical characteristics as copper wires, and has the advantage of being resistant to corrosion, light weight, and low cost.

이상의 설명에서 본 발명은 특정의 실시 예와 관련하여 도시 및 설명하였지만, 특허청구범위에 의해 나타난 발명의 사상 및 영역으로부터 벗어나지 않는 한도 내에서 다양한 개조 및 변화가 가능하다는 것을 이 기술분야에서 통상의 지식을 가진 자라면 누구나 쉽게 알 수 있을 것이다.While the invention has been shown and described in connection with specific embodiments thereof, it is well known in the art that various modifications and changes can be made without departing from the spirit and scope of the invention as indicated by the claims. Anyone who has a can easily know.
