Description

무탈피 전선이음 커넥터용 터미널 및 이를 갖는 전선이음 커넥터Terminals for Stripped Wire Joint Connectors and Wire Joint Connectors Having the Same

본 발명은 무탈피 전선이음 커넥터용 터미널 및 이를 갖는 전선이음 커넥터에 관한 것으로서, 좀더 상세하게 설명하면 전선의 피복을 벗기지 않고 통전 가능하게 연결할 때 전선의 내부 심선과 터미널이 안정적인 접촉이 이루어지도록 하기위하여 접촉면적을 넓혀 접촉불량이나 발열이 일어나는 것을 방지하기 위하여 개발된 무탈피 전선이음 커넥터용 터미널 및 이를 갖는 전선이음 커넥터에 관한 것이다.The present invention relates to a terminal for a non-stripping wire joint connector and a wire joint connector having the same, in more detail, in order to ensure stable contact between the inner core of the wire and the terminal when electrically connected without peeling off the covering of the wire. The present invention relates to a terminal for a stripped wire joint connector and a wire joint connector having the same, which are developed to widen a contact area and prevent contact failure or heat generation.

전선을 분리되어 있는 하나 이상의 다른 전선과 연결하거나 전선의 끝단을 장치에 연결하는 방법은 주로 전선의 피복을 벗긴 후 노출된 심선이 복수 개로 이루어져 있을 경우 비틀어 정리한 후 연결하는 것이 일반적이다.Connecting wires with one or more separate wires or connecting the ends of the wires to the device is usually done by stripping the wires and twisting them together if there are multiple exposed core wires.

여기에 서로 다른 전선을 연결할 경우에는 절연 테이프로 감아 다른 연결부와의 접촉과 외부 물체 및 외부의 습기로부터 차단하도록 하고 있으나 이러한 이음작업은 상당한 번거롭고 시간이 소요되는 단점이 있다.When connecting different wires here, it is wound with insulation tape to shield it from contact with other connections, external objects, and moisture from the outside. However, such a jointing operation is quite cumbersome and time-consuming.

또한, 연결되어 있는 전선 간의 축 방향 인장력에 대한 저항력도 매우 떨어져서 전선 간의 접속이 축 방향으로 쉽게 분리 및 이탈되는 등의 문제점을 갖고 있었다.In addition, the resistance to the axial tensile force between the connected wires is also very low, there was a problem that the connection between the wires easily separated and separated in the axial direction.

이에 다양한 선행기술에서 전선의 피복을 벗기지 않고 커넥터에 장착할 때 피복 일부를 절단하는 칼날을 구비하는 터미널에 의하여 접촉되도록 하는 방안이 개발되었으나 접촉면적이 작고 안정성이 부족하여 접촉불량이 발생하거나 접촉한 부분에서 저항에 의한 발열 현상이 발생하는 문제점이 있었다.Therefore, in the various prior arts, a method of contacting by a terminal having a blade for cutting a part of the covering when the connector is attached to the connector without removing the covering of the wire has been developed, but the contact area is small and the stability is insufficient, resulting in poor contact or contact. There was a problem that a heat generation phenomenon caused by resistance in the portion.

이러한 문제점을 심선의 외면에 터미널의 일부가 점 접촉을 하기 때문에 발생하는 것으로 이를 해결하기 위한 방안으로 접촉점을 늘이는 다중 접촉이라는 복잡한 구조를 가지게 되었다.This problem occurs because part of the terminal makes point contact on the outer surface of the core wire. As a solution to this problem, it has a complicated structure called multi-contact that extends the contact point.

본 발명은 전술한 문제점을 해결하기 위하여 개발된 것으로서, 그 목적은 무탈피 전선이음 커넥터에서 전선의 심선과 접촉하는 터미널이 외부의 힘에 의하여 유동하지 않으면서 안정적이고 넓은 접촉면적을 가질 수 있도록 하는 무탈피 전선이음 커넥터용 터미널 및 이를 갖는 전선이음 커넥터를 개발하는 것에 있다.The present invention was developed to solve the above-mentioned problems, and an object thereof is to allow a terminal in contact with a core of a wire in a stripless wire joint connector to have a stable and wide contact area without flowing by external force. The present invention provides a terminal for a stripless wire joint connector and a wire joint connector having the same.

상기와 같은 목적을 달성하기 위하여 본 발명은 폭 방향으로 일정간격 이격되어 서로 마주보는 칼날 사이로 형성되는 전선투입부와, 상기 칼날과 연결되고 일정간격 이격된 채로 서로 대향하여 심선안착부를 형성하는 한 쌍의 직립편과, 상기 한 쌍의 직립편 하단부를 연결하는 연결편으로 이루어지는 전선 이음 커넥터용 터미널에 있어서, 상기 한 쌍의 직립편의 일측에는 상기 심선안착부로 삽입되는 심선을 가압하는 누름돌부가 형성되고, 타측에는 상기 누름돌부에 대응되어 상기 심선이 안착되는 안착홈부가 형성됨을 특징으로 한다.In order to achieve the above object, the present invention is a pair of wire input portion formed between the blades facing each other spaced apart at regular intervals in the width direction, and a pair forming a core wire seating portion facing each other while being spaced apart from the blades and spaced at regular intervals. In the terminal for a wire joint connector consisting of an upright piece of the pair, and a connecting piece for connecting the lower end of the pair of upright pieces, one side of the pair of upright pieces is formed with a pressing protrusion for pressing the core wire inserted into the core wire seating portion, The mounting groove is formed on the side to correspond to the pressing protrusion to which the core wire is seated.

이에 의해, 전선의 피복이 벗겨진 상태의 심선이 직립편에 넓은 면적으로 접촉하게 된다. As a result, the core wire in the state where the covering of the wire is peeled off is brought into contact with the upright piece in a large area.

아울러, 상기 커팅날은 상기 전선의 길이방향으로 일정간격 이격되어 서로 마주보도록 형성되고 서로 전기적으로 연결된 것임을 특징으로 한다.In addition, the cutting blades are formed so as to face each other spaced apart at regular intervals in the longitudinal direction of the wire and are characterized in that they are electrically connected to each other.

이에 의하면, 커팅날을 2중, 3중으로 일정간격 이격된 채로 배치하여, 심선의 접촉면적을 더욱 증가시킬 수가 있게된다.According to this arrangement, the cutting edges are arranged at regular intervals in double and triple, so that the contact area of the core wire can be further increased.

이러한 특징을 가지는 터미날은 여러 형태의 커넥터에 체결되어 무탈피 전선 이음 커넥터를 형성할 수 있게된다. Terminals having these characteristics can be fastened to various types of connectors to form a stripless wire joint connector.

즉 상기의 커넥터를 상면이 개방되고 전선의 외경에 상응하는 함몰된 형상의 전선안착홈을 포함하여 전선의 하부가 안착하는 절연성의 하부커넥터에 또는 저면이 개방되고 상기 전선의 외경에 상응하는 함몰된 형상의 전선누름홈을 포함하여 전선의 상부가 안착하고 상기 하부커넥터와 체결되는 절연성의 상부커넥터에 포함함할 수 있다.That is, the connector has an upper surface open and a recessed shape of the wire seating groove corresponding to the outer diameter of the wire, or an insulated lower connector on which the lower part of the wire is seated or the bottom of the connector is opened and corresponding to the outer diameter of the wire. Including the wire pressing groove of the shape may be included in the insulating upper connector to the upper portion of the wire is seated and fastened to the lower connector.

상술한 바와 같이 본 발명은 전선이 터미널에 삽입되면서 칼날에 의하여 양측 피복이 절개되고 수직으로 평행하게 절개된 공간 사이로 심선의 외면이 밀착하면서 하강한 후 일측은 곡선으로 돌출되고 마주보는 타측은 곡선으로 함몰되는 공간에서 꺾이면서 고정되게 함으로서 터미널과 심선의 접촉면적이 늘어나도록 하여 저항에 의한 발열 현상을 줄이고 외력에도 밀착한 상태를 유지하도록 하여 안정적인 접촉이 이루어지는 효과가 있다.As described above, in the present invention, as the wire is inserted into the terminal, both sides of the sheath are cut by the blade, and the outer surface of the core wire descends into close contact between the spaces cut vertically and parallelly, and then one side protrudes into a curve and the other side thereof faces into a curve. By being fixed while being bent in a recessed space, the contact area between the terminal and the core wire is increased to reduce heat generation due to resistance and to maintain a close contact with external force, thereby achieving stable contact.
