Abstract

A contact element of a shield connector used in an electric vehicle is provided to connect with a shield layer of a shield wire electrically and fix on an outer coat of the shield wire stably if the outer coat of the shield wire is peeled without performing a complicated process that the outer coat of the shield wire is peeled and compressed. A contact element of a shield wire(1) is used in an electric vehicle. The contact element includes a U-shaped body(31) and at least one knife blade(34) provided within the body. The body has a concave portion(32) for housing the shield wire therethrough. The shield wire is inserted into the contact element while the knife blade of the contact element peels off an outer coat of the shield wire, thereby electrically connecting the contact element and a shield layer(14) of the shield wire.

전기 자동차에 사용하는 차폐 커넥터의 접촉자{Contacting Member of Shield Connnector Which Is Used in Electric Vehicle}Contact member of shield connector which is used in electric vehicle

도 1은 본 발명에 의한 접촉자와 차폐 전선을 도시한 사시도.1 is a perspective view showing a contactor and a shielded wire according to the present invention.

본 발명은 전기 자동차에 사용하는 차폐 커넥터의 접촉자에 관한 것으로서 특히, 압착을 간단하게 수행할 수 있는 접촉자에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a contactor of a shielded connector for use in an electric vehicle, and more particularly to a contactor capable of simply performing a crimping.

종래에 차폐 커넥터로서 일본특허출원공개번호 특개평7-245153호에 개시되어 있는 것이 있는데, 이 커넥터에서는 접속하는 금속 단자가 커넥터 하우징에 장착되고, 그 금속 단자에 차폐 전선의 도체가 압착함으로써 접속되는 구조였다. 그리고 차폐 전선의 차폐층에 금속 단자를 포위하는 차폐쉘이 접속되어 구성된다. 이 일본특허출원공개문헌은 본 명세서에 선행기술로서 참조된다.Conventionally, a shielded connector is disclosed in Japanese Patent Application Laid-open No. Hei 7-245153. In this connector, a metal terminal to be connected is mounted on the connector housing, and the conductor of the shielded wire is connected to the metal terminal by crimping. It was a rescue. The shielding shell surrounding the metal terminal is connected to the shielding layer of the shielding wire. This Japanese patent application publication is referred to as a prior art in this specification.

그런데 이러한 공지 기술에서는, 배럴(barrel)부를 차폐층의 노출부분에 압착시키게 되는데, 이러한 압착은 고가의 장치를 필요로 해서 제작 원가를 증대시키 는 문제점이 있었다.By the way, in this known technique, the barrel portion is pressed against the exposed portion of the shielding layer, but this pressing requires an expensive device and increases the manufacturing cost.

상기 종래 기술의 단점을 보완하기 위한 차폐 커넥터로서 일본특허출원공개번호 특개평11-40274호에 개시된 커넥터가 있다. 여기에 개시되어 있는 접속 장치는 탄성 접속편과 압입부로 이루어져 있다. 차폐 전선의 차폐층과 절연 내피 사이에 압입부를 압입하고 그에 연결된 탄성 접속편이 차폐 커넥터의 차폐쉘과 접속하는 구조이다. 이 일본특허출원공개문헌도 본 명세서에 선행기술로서 참조된다.There is a connector disclosed in Japanese Patent Application Laid-open No. Hei 11-40274 as a shielding connector for supplementing the disadvantages of the prior art. The connection apparatus disclosed here consists of an elastic connection piece and a press-fit part. The press-fitting part is pressed between the shielding layer of the shielding wire and the insulating inner shell, and an elastic connecting piece connected thereto is connected to the shielding shell of the shielding connector. This Japanese patent application publication is also referred to herein as a prior art.

본 발명은 차폐 전선의 외부 피복을 벗기고 압착하는 복잡한 공정이 필요없이 차폐 전선의 외부 피복을 벗기면서 차폐층과 전기적으로 접속될 수 있는 동시에 전선 외피에 고정될 수 있도록 하는 접촉자를 제공하는 것을 목적으로 한다.The present invention aims to provide a contact that can be electrically connected to the shielding layer and can be secured to the wire sheath while removing the outer sheath of the shield wire without the complicated process of stripping and crimping the outer sheath of the shield wire. do.

전술한 목적을 달성하기 위한 본 발명에 의한 접촉자는, U자형 형상을 가지는 몸통부와, 상기 몸통부의 내측에 서로를 향해 연장하는 칼날부를 포함한다. 그리고 상기 몸통부에는 차폐 전선을 수용하기 위한 오목부가 형성되어 있고, 상기 칼날부는 상기 차폐 전선의 외부 피복을 파고 들어가 벗기고 상기 접촉자가 차폐층에 전기적으로 접속되도록 배치되어 있다.The contactor according to the present invention for achieving the above object includes a body portion having a U-shape and a blade portion extending toward each other inside the body portion. The body portion is provided with a recess for accommodating the shielded wire, and the blade portion is arranged to dig into and remove the outer sheath of the shielded wire and to electrically connect the contactor to the shielding layer.

이러한 구성에 의하면 접촉자를 차폐 전선에 강제 압입함으로써 전선의 외부 피복을 접촉자의 칼날부로 벗기면서 차페층과 전기적으로 접속하는 동시에 전선 외 피에 고정될 수 있기 때문에, 종래에 차폐 전선의 외부 피복을 벗기고 압착하는 방법에 비해 조립이 간편한 장점이 제공된다.According to this configuration, the outer sheath of the shielded wire can be electrically connected to the shielding layer while being fixed to the outer sheath of the wire while peeling the outer sheath of the wire with the blade of the contactor by forcibly pressing the contactor into the shielded wire. The advantages of ease of assembly over the crimping method are provided.

이하에서는 첨부 도면을 참조하여 본 발명의 양호한 실시예에 대해서 설명하기로 한다.Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

도 1에는 본 발명에 의한 접촉자와 차폐 전선의 사시도가 도시되어 있다.1 shows a perspective view of a contactor and shielded wire according to the present invention.

차폐 전선(1)은 도 1에 도시되어 있는 바와 같이, 전선다발(11)과, 내부 피복(13)과, 차폐층(14)과, 외피(15)로 구성되어 있다.As shown in FIG. 1, the shielding wire 1 is composed of a wire bundle 11, an inner covering 13, a shielding layer 14, and an outer shell 15.

접촉자(3)는 대략 U자형 형상을 취하는 몸통부(31)와, 상기 차폐 전선이 수용되는 오목부(32)와, 상기 몸통부(31)의 내측에 서로를 향해 연장하는 두 개의 칼날부(34)와, 돌출부(35)로 구성되어 있다. 칼날부(34)는 적어도 두 개가 제공되는 것이 바람직하다. 칼날부(34)는 차폐 전선(1)의 외부 피복(15)을 벗기면서 차폐층(14)에 접속하도록 되어 있다. 칼날부(34)는 도 1에는 두 개가 제공되는 것으로 도시되어 있지만, 오목부(32)의 아래쪽에 한 개가 제공될 수도 있고, 그 개수에 본 발명의 권리범위게 제한되는 것은 아니다.The contactor 3 has a trunk portion 31 having a substantially U-shape, a recess 32 in which the shielding wire is accommodated, and two blade portions extending toward each other inside the trunk portion 31 ( 34 and the protruding portion 35. At least two blade parts 34 are preferably provided. The blade portion 34 is connected to the shielding layer 14 while peeling off the outer covering 15 of the shielding wire 1. Although one blade portion 34 is shown as being provided in FIG. 1, one may be provided below the concave portion 32, and the number thereof is not limited to the scope of the present invention.

즉 도 1의 화살표 방향으로 차폐 전선(1)에 접촉자(3)를 강제 압입시키면 칼날부(34)가 외부 피복(15)을 파고 들어가서 외부 피복을 벗기고, 그 내부에 제공되는 차폐층(14)에 접속되게 되어 종래 기술, 즉 차폐 전선(1)의 외부 피복(15)을 벗기고 압착하는 방법에 비해서 조립이 매우 간편해지는 장점이 제공된다.That is, when the contactor 3 is forcibly pressed into the shielding wire 1 in the direction of the arrow of FIG. 1, the blade part 34 penetrates the outer sheath 15 to peel off the outer sheath, and the shielding layer 14 provided therein is provided. This provides the advantage that the assembly is very simple compared to the prior art, ie the method of stripping and crimping the outer sheath 15 of the shielded wire 1.

종래에는 전기 자동차의 차폐 전선의 외부 피복을 벗기고 압착하는 공정을 사용하였는데, 본 발명에 의하면 그러한 공정이 필요없이, 접촉자를 차폐 전선에 강제 압입시킴으로써 동일한 목적을 달성할 수 있게 되는 효과가 제공된다.Conventionally, the process of peeling and crimping the outer covering of the shielding wire of an electric vehicle is used. According to the present invention, the same object can be achieved by forcibly pressing a contactor into the shielding wire without such a step.

이상 첨부 도면을 참조하여 본 발명의 양호한 실시예에 대해서 설명하였지만 본 발명의 권리범위는 후술하는 특허청구범위에 의하여 정하여지며 전술한 실시예 및/또는 첨부 도면에 의해 제한되는 것으로 해석되어서는 아니된다. 그리고 특허청구범위에 기재된 발명의, 당업자에게 자명한 개량, 변경 및/또는 수정도 본 발명의 권리범위에 포함된다.Although the preferred embodiments of the present invention have been described above with reference to the accompanying drawings, the scope of the present invention is defined by the claims below and should not be construed as limited by the embodiments and / or accompanying drawings. . In addition, improvements, changes, and / or modifications apparent to those skilled in the art of the invention described in the claims are included in the scope of the present invention.
