Description

세레이션부를 구비한 단자{TERMINAL HAVING SERRATION PART}[0001] TERMINAL HAVING SERRATION PART [0002]

본 발명은 단자에 관한 것으로, 구체적으로는, 단자에 형성된 세레이션부에 관한 것이다. The present invention relates to a terminal, and more particularly, to a serration part formed on a terminal.

도 1은 종래의 세레이션부를 구비한 단자의 구조를 도시한 사시도이다. 1 is a perspective view showing a structure of a terminal having a conventional serration part.

도 1에 도시한 바와 같이, 단자(10)는 상대측 단자(미도시)에 전기 접속되는 전기 접속부(11)와, U 형상 단면을 갖고 복수의 소선(전선(1))을 꼬아서 형성된 도체를 압착되는 도체 압착부(12) 및 전선(1)의 피복부에 고정되는 피복 압착부(13)를 포함하고 있다. As shown in Fig. 1, the terminal 10 includes an electrical connecting portion 11 electrically connected to a mating terminal (not shown), and a conductor formed by twisting a plurality of element wires (electric wire 1) A conductor crimping portion 12 to be crimped and a cover crimping portion 13 to be fixed to the covering portion of the electric wire 1. [

그리고, 도체 압착부(12)의 판면에는 3개의 직선 형태의 홈을 갖는 세레이션(12a)이 도체 함몰 형성되어 있다. 이러한 홈은 도체의 길이 방향에 대하여 수직을 이루는 방향으로 형성되어 있다. A serration 12a having three linear grooves is formed on the plate surface of the conductor crimp portion 12 by conductor depression. These grooves are formed in a direction perpendicular to the longitudinal direction of the conductor.

단자(10)의 도체 압착부(12)가 전선(1)의 도체를 압착할 때, 도체의 소선은 변형되면서 홈 형상의 세레이션(12a) 내에 압입된다. When the conductor crimping portion 12 of the terminal 10 presses the conductor of the electric wire 1, the strand of the conductor is deformed and press-fitted into the serrated serration 12a.

이 때, 세레이션(12a)의 에지인 세레이션 에지는 도체의 소선의 표면의 산화막을 파괴하여 새롭게 형성된 면이 형성된다. 그 결과로서, 이러한 새롭게 형성된 표면은 단자(10)의 도체 압착부(12)와 밀착하여 단자(10)와 전선(1)이 서로 전기적으로 접속된다.At this time, the serration edge, which is the edge of the serration 12a, breaks the oxide film on the surface of the conductor of the conductor and forms a newly formed surface. As a result, the newly formed surface is brought into close contact with the conductor crimping portion 12 of the terminal 10, so that the terminal 10 and the electric wire 1 are electrically connected to each other.

그런데, 이러한 종래의 세레이션부를 구비한 단자에 있어서, 세레이션(12a)이 도체의 길이 방향에 대하여 수직을 이루는 방향으로 단순히 직선 형태로 형성되어 있기 때문에 전선(1)에 형성된 산화피막을 효과적으로 파괴하지 못하여 접속 불량이 발생한다는 문제점이 있다. However, since the serrations 12a are formed in a straight line in the direction perpendicular to the longitudinal direction of the conductor, the oxide film formed on the electric wire 1 is effectively destroyed There is a problem that connection failure occurs.

또한, 세레이션(12a)이 단순히 직선 형태의 홈으로 형성되어 있기 때문에 전선(1)의 도체를 압착하는 압착력이 저하되어 의도하지 않게 전선(1)과 단자(10)가 이탈될 수 있다는 문제점이 있다. Further, since the serrations 12a are simply formed as straight grooves, there is a problem that the pressing force for pressing the conductor of the electric wire 1 is lowered, and the electric wire 1 and the terminal 10 may be unintentionally separated have.

본 발명은 상기와 같은 문제점을 감안하여 안출된 것으로, 단자의 압착부에 구비된 세레이션부의 꼭지점을 형성하는 각각의 모서리가 일정 각도를 이루도록 뾰족하게 가공됨으로써 전선의 산화피막을 효과적으로 파괴함으로써 전기적인 접속 효율을 높임과 동시에 단자의 압착부가 전선을 압착하는 고착력을 향상시킴으로써 단자로부터 임의로 전선이 이탈됨을 방지할 수 있는 세레이션부를 구비한 단자를 제공함에 목적이 있다. SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and it is an object of the present invention to provide a method of manufacturing a semiconductor device, in which an edge of an edge of a serration portion provided in a crimping portion of a terminal is sharp- It is an object of the present invention to provide a terminal having a serration part which can improve the connection efficiency and improve the fastening force of the crimping part of the terminal so as to prevent the electric wire from being disengaged from the terminal arbitrarily.

본 발명의 목적들은 이상에서 언급한 목적으로 제한되지 않으며, 언급되지 않은 또 다른 목적들은 아래의 기재로부터 당업자에게 명확하게 이해되어질 수 있을 것이다.The objects of the present invention are not limited to the above-mentioned objects, and other objects not mentioned may be clearly understood by those skilled in the art from the following description.

상기와 같은 본 발명의 목적을 달성하기 위한 본 발명의 일 실시예에 따른 세레이션부를 구비한 단자는, 전선의 피복이 제거된 영역에 압착됨으로써 통전이 이루어지도록 하는 압착부와 상기 피복이 압착되도록 하는 피복 압착부를 구비한 단자에 있어서, 양단이 상호 대향되게 절곡 형성된 상기 압착부가 상호 중첩되는 방향으로 압착시에 상기 전선의 피복이 제거된 영역과 상호 접촉되어 상기 압착부와의 고착력이 발생하도록 상기 압착부의 판면에는 상호 대향되게 배치되는 두 쌍의 변이 각각 내측으로 굴곡지게 함몰 형성되며 각각의 변이 상호 연결되는 영역이 외측으로 굴곡지게 형성되어 폐곡선을 형성하며 상기 폐곡선이 열과 행을 이루도록 배열되는 복수의 세레이션으로 구성되는 세레이션부를 포함한 것을 특징으로 한다. According to an aspect of the present invention, there is provided a terminal including a serration portion, the terminal including a squeeze portion for squeezing the squeezed portion of the squeezed wire, The crimping portion is bent so that both ends of the crimping portion are mutually opposed to each other to come into contact with a region where the covering of the electric wire is removed at the time of crimping so that a fixing force between the crimping portion and the crimping portion is generated Wherein a pair of sides disposed opposite to each other on the plate surface of the crimping portion is formed to be curved inwardly to be inwardly curved and a region where the respective sides are mutually connected is bent outward to form a closed curve, And a serration part composed of a serration part of the serration part.

여기서, 상기 세레이션은 상호 대향하는 두 쌍의 변 중에서 상대적으로 짧은 한 쌍의 변이 상기 전선의 피복이 제거된 영역이 연장되는 방향을 따라 배열될 수 있다. Here, the serration may be arranged along a direction in which a relatively short pair of two pairs of mutually opposed sides extends in a region where the covering of the wire is removed.

그리고, 상기 세레이션의 종단면에서 상기 전선이 상기 피복 압착부와 상대적으로 더 가까운 위치에 배치된 두 모서리가 이루는 각은 직각을 형성하며, 상기 피복 압착부와 상대적으로 먼 위치에 배치된 두 모서리가 이루는 각은 둔각을 형성할 수 있다. An angle formed by the two corners disposed at a position relatively closer to the cover crimping portion in the vertical section of the serration forms a right angle and two corners disposed at positions relatively far from the cover crimping portion The angle formed can form an obtuse angle.

또한, 상기 세레이션은 상기 압착부에 연결되는 상기 전선의 배치 방향과 수직을 이루는 상기 압착부의 폭방향을 따라 일정 간격을 이격되게 배열되어 하나의 행을 형성하되, 이웃하는 행과는 상호 엇갈리도록 교번적으로 배열될 수 있다. The serration may be arranged at predetermined intervals along the width direction of the crimping portion perpendicular to the direction of arrangement of the wires connected to the crimping portion to form one row, Can be alternately arranged.

아울러, 상기 세레이션의 상기 폭방향을 따른 이격 거리는 이웃하는 행을 형성하는 세레이션과 상호 중첩되는 영역이 존재할 수 있는 거리로 형성될 수 있다. In addition, the separation distance along the width direction of the serration may be a distance such that there is an overlapping area with the serrations forming the neighboring rows.

전술한 과제해결 수단에 의해 본 발명은, 단자의 압착부에 구비된 세레이션부의 꼭지점을 형성하는 각각의 모서리가 일정 각도를 이루도록 뾰족하게 가공됨으로써 전선의 산화피막을 효과적으로 파괴함으로써 전기적인 접속 효율을 높일 수 있는 효과가 있다. According to the present invention, the edges of the serrations formed in the crimping portions of the terminals are sharpened so that the corners of the serrations form a certain angle, thereby effectively breaking the oxide film of the wires, There is an effect that can be increased.

또한, 단자의 압착부가 전선을 압착하는 고착력을 향상시킴으로써 단자로부터 임의로 전선이 이탈됨을 방지할 수 있는 효과가 있다. Further, the crimping portion of the terminal improves the fixing force for pressing the electric wire, thereby preventing the electric wire from being disengaged from the terminal arbitrarily.

이들 도면에 도시한 바와 같이, 본 발명의 일 실시예에 따른 세레이션부를 구비한 단자는, 전선(1)의 피복이 제거된 영역에 압착됨으로써 통전이 이루어지도록 하는 압착부(110)와 상기 피복이 압착되도록 하는 피복 압착부(120)를 구비한 단자(100)에 있어서, 양단이 상호 대향되게 절곡 형성된 상기 압착부(110)가 상호 중첩되는 방향으로 압착시에 상기 전선(1)의 피복이 제거된 영역과 상호 접촉되어 상기 압착부(110)와의 고착력이 발생하도록 상기 압착부(110)의 판면에는 상호 대향되게 배치되는 두 쌍의 변이 각각 내측으로 굴곡지게 함몰 형성되며 각각의 변이 상호 연결되는 영역이 외측으로 굴곡지게 형성되어 폐곡선을 형성하며 상기 폐곡선이 열과 행을 이루도록 배열되는 복수의 세레이션(111)으로 구성된 것을 특징으로 한다.As shown in these drawings, a terminal having a serration part according to an embodiment of the present invention includes a crimping part 110 for making electric current by being pressed to a region where the covering of the electric wire 1 is removed, (100) having a cover crimping portion (120) for crimping the crimping portion (110), wherein the crimping portion (110) is bent so that both ends thereof face each other, Two pairs of mutually opposing sides are formed so as to bend inwardly on the plate surface of the crimping portion 110 so that a bonding force with the crimping portion 110 is generated in mutual contact with the removed region, And a plurality of serrations (111) which are arranged so that the closed curve forms a closed curve and the closed curve forms a row and a column.

단자(100)는 전선(1)과 전기적으로 접속되어 다른 기기에 연결됨으로써 전원을 공급하거나 혹은 전기적인 신호를 송수신하도록 하는 부재로서, 일측에는 상향 개구된 형태로 절곡 형성되어 전선(1)의 피복이 제거된 부분을 압착하여 고착력이 발생하도록 하는 압착부(110)가 구비되어 있다. The terminal 100 is electrically connected to the electric wire 1 and is connected to another device to supply electric power or transmit / receive an electric signal. The terminal 100 is formed at one side of the electric wire 1, And a pressing portion 110 for pressing the removed portion to generate a fixing force.

그리고, 전선(1)이 연결되는 방향을 따라 압착부(110)의 후방에는 전선(1)의 피복을 감싸도록 하여 전선(1)이 이탈됨을 방지하는 피복압착부(120)가 구비되는데, 피복압착부(120)의 전선(1)의 피복을 완전히 감쌀 수 있도록 압착부(110)의 폭보다 더 큰 폭을 갖도록 형성되어 있다. A cover crimping portion 120 is provided at the rear of the crimping portion 110 along the direction in which the wire 1 is connected so as to cover the cover of the wire 1 to prevent the wire 1 from being separated. Is formed to have a width larger than the width of the crimping portion (110) so that the covering of the wire (1) of the crimping portion (120) can be completely covered.

전선(1)이 연결되는 방향을 따라 압착부(110)의 전방 측인 피복압착부(120)의 반대편에는 전기접속부(130)가 구비되어 있으며, 이러한 전기접속부(130)가 다른 기기에 삽입되어 연결됨으로써 전기적인 접속이 이루어지도록 한다. The electrical connection part 130 is provided on the opposite side of the cover crimping part 120 which is the front side of the crimping part 110 along the direction in which the electric wire 1 is connected, So that an electrical connection is established.

본 발명은 압착부(110)의 표면에 형성된 세레이션부에 관한 것으로 이러한 세레이션부에 의하여 전선(1)과 단자(100) 사이의 고착력을 향상시킬 수 있도록 하여 전기적인 접속 불량이 발생됨을 방지하고, 전선(1)이 임의로 단자에서 이탈됨을 방지할 수 있게 된다. The present invention relates to a serration part formed on the surface of a crimping part 110. It is possible to improve the fixing force between the electric wire 1 and the terminal 100 by the serration part, And it is possible to prevent the electric wire 1 from being arbitrarily detached from the terminal.

상기 세레이션부는 압착부(110)의 판면에는 상호 대향되게 배치된 두 쌍의 변이 내측으로 굴곡지게 형성되고, 상기 변이 상호 연결되는 영역이 외측으로 굴곡지게 형성되어 폐곡선을 형성하며, 상기 폐곡선은 열과 행을 이루도록 배열되는 복수의 세레이션(111)으로 구성되어 있다. The serration part is formed by bending two pairs of mutually opposing sides disposed on the plate surface of the crimping part 110 and forming a closed curve by bending the areas where the sides are mutually connected to form a closed curve, And a plurality of serrations 111 arranged so as to form rows.

세레이션(111)은 압착부(110)의 판면에 함몰 형성된 복수의 홈을 일컫는 것으로서, 압착부(110)의 판면에 복수의 세레이션(111)을 형성함으로써 압착부(110)가 압착시에 압착부(110)에 놓여진 전선(1)의 피복이 제거된 부분이 압착되면서 피복이 제거된 부분의 산화피막이 파괴되어 단자(100)와 전선(1) 사이의 원활한 전기적인 접속이 이루어지도록 할 수 있다. The serration 111 refers to a plurality of grooves formed on the plate surface of the press portion 110 and a plurality of serrations 111 are formed on the surface of the press portion 110 so that the press portion 110 is pressed The coated portion of the electric wire 1 placed on the crimping portion 110 is compressed and the oxide film of the portion where the covering is removed is destroyed so that the electric connection between the terminal 100 and the electric wire 1 can be performed smoothly have.

세레이션(111)은 상호 대향하는 두 쌍의 변 중에서 상대적으로 짧은 한 쌍의 변이 상기 전선(1)의 피복이 제거된 영역이 연장되는 방향을 따라 배열되는 것이 바람직한데, 이는 단자(100)로부터 전선(1)이 이탈시에 힘을 받는 방향이 세레이션(111)의 오목한 부분과 나란하도록 함으로써 상기 힘에 대한 저항을 높여서 전선(1)이 용이하게 이탈되지 않도록 하기 위함이다. The serrations 111 are preferably arranged such that a relatively short pair of two mutually opposed sides are arranged along a direction in which a covered area of the wire 1 is extended, So that the direction in which the wire 1 receives the force when it is released is parallel to the concave portion of the serrations 111 so as to increase the resistance against the force so that the wire 1 can not be easily detached.

그리고, 세레이션(111)의 종단면에서 전선(1)이 단자(100)에서 이탈되는 방향을 따라 피복 압착부(120)와 상대적으로 더 가까운 위치에 배치된 두 모서리(111a)가 이루는 각은 직각을 형성하며, 상대적으로 피복 압착부(120)와 먼 위치에 배치된 두 모서리(111b)가 이루는 각은 둔각을 형성하도록 할 수 있다. The angle formed by the two edges 111a disposed closer to the cover crimping portion 120 along the direction in which the electric wire 1 is separated from the terminal 100 in the vertical cross section of the serrations 111, And an angle formed by the two corners 111b located relatively far from the cover crimping portion 120 may form an obtuse angle.

이는, 단자(100)로부터 전선(1)이 이탈시에 힘을 받는 방향에 대하여 전방은 직각을 형성함으로써 전선(1)의 피복이 제거된 도체가 수직 방향으로 세레이션(111)에 일정 깊이 삽입되어 걸림되도록 하고, 후방은 둔각을 형성함으로써 전선(1)의 피복이 제거된 도체가 전방보다 깊은 깊이로 삽입되어 결속력을 높일 수 있도록 하여 전선(1)이 용이하게 이탈되지 않도록 하기 위함이다. This is because a conductor having a covered wire of the electric wire 1 is inserted at a predetermined depth into the serration 111 in the vertical direction by forming a right angle with respect to a direction in which the electric wire 1 is subjected to the force when the terminal 100 is exited from the terminal 100, And the rear surface is formed with an obtuse angle so that the conductor from which the sheath of the wire 1 is removed is inserted at a deeper depth than the front to increase the binding force so that the wire 1 can not be easily detached.

또한, 도 3에 도시한 바와 같이, 세레이션(111)은 압착부(110)와 연결되는 전선(1)이 배치되는 방향과 수직을 이루는 압착부(110)의 폭방향을 따라 일정 간격을 이루도록 배열되어 하나의 행을 형성하되, 이웃하는 행과는 상호 엇갈리도록 교번적으로 배열되도록 할 수 있다. 3, the serrations 111 are formed at regular intervals along the width direction of the crimping portion 110 that is perpendicular to the direction in which the electric wires 1 connected to the crimping portion 110 are arranged It is possible to arrange a plurality of rows so as to be alternately arranged with respect to each other.

이는, 압착부(110)가 전선(1)의 피복이 제거된 도체를 압착시에 압착되는 면적을 증대시킴으로써 압착부(110)와 전선(1)의 피복이 제거된 도체 사이의 고착력을 향상시킬 수 있는 효과가 있다.  This is because when the crimping portion 110 increases the area to which the conductor coated with the wire 1 is crimped at the time of crimping, the fixing strength between the crimping portion 110 and the conductor in which the sheath of the wire 1 is removed is improved There is an effect that can be made.

그리고, 상기 고착력을 더욱 향상시키기 위하여 세레이션(111)의 이격거리는 하나의 행을 형성하는 세레이션이 이웃하는 행을 형성하는 세레이션과 중첩될 수 있을 정도의 길이로 형성하는 것이 더욱 효과적이다. In order to further improve the fixation force, it is more effective to form the separation distance of the serrations 111 so that the serrations forming one row can be overlapped with the serrations forming the neighboring rows .

이는, 세레이션(111)이 중첩되는 영역의 경우에는 세레이션(111)이 중첩되지 않는 영역보다 2배 가까이 세레이션(111)과 상기 도체 사이의 접촉 면적을 확보할 수 있으므로 이들 사이의 고착력 역시 마찬가지로 2배 가까이 증대시킬 수 있는 효과가 있다. This is because, in the case of the region where the serrations 111 are overlapped, the contact area between the serrations 111 and the conductor can be ensured to be nearly twice that of the region where the serrations 111 do not overlap, Likewise, there is an effect that can be increased by nearly two times.

상술한 바와 같은 구성을 갖는 본 발명은 단자의 압착부에 구비된 세레이션부의 에지를 직각으로 형성함으로써 전선(1)의 산화피막을 효과적으로 파괴함으로써 전기적인 접속 효율을 높임과 동시에 단자의 압착부가 전선(1)을 압착하는 고착력을 향상시킴으로써 단자로부터 임의로 전선(1)이 이탈됨을 방지할 수 있는 효과가 있다. In the present invention having the above-described structure, the edge of the serration portion provided in the crimping portion of the terminal is formed at right angles to effectively break the oxide film of the wire 1, thereby increasing the electrical connection efficiency, It is possible to prevent the electric wire 1 from being disengaged from the terminal arbitrarily by improving the fixing force for pressing the electric wire 1.
