Description

전기 커넥터의 컨택트 단자{CONTANCT TERMINAL FOR AN ELECTRIC CONNECTOR}CONTACT TERMINAL FOR AN ELECTRIC CONNECTOR [0002]

본 발명은 전기 커넥터의 컨택트 단자에 관한 것으로, 특히 전기전도성이 우수한 금속 박판을 구부림성형하여 스프링편으로 형성한 컨택트 단자에 관한 것이다. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a contact terminal of an electrical connector, and more particularly to a contact terminal formed of a spring piece by bending a thin metal plate having excellent electrical conductivity.

전자기기에 장착되는 전기 커넥터(이하, 간단히 '커넥터'라 한다.)는 전기적으로 접속하고자 하는 부품별로 예컨대, 배터리 커넥터, 카드 커넥터, I/O 커넥터 등과 같이 다양한 종류가 알려져 있다. 이들 커넥터는 접속하고자 하는 부품의 배선과 기판의 배선을 서로 통전시키는 컨택트 단자를 적어도 하나 이상 가지고 있다. BACKGROUND ART [0002] Various types of electrical connectors (hereinafter, simply referred to as 'connectors') mounted on electronic devices are known, for example, battery connectors, card connectors, I / O connectors, and the like for respective parts to be electrically connected. These connectors have at least one contact terminal for electrically connecting the wiring of the component to be connected and the wiring of the board to each other.

이러한 컨택트 단자는 아래 특허문헌1에 개시되어 있는 바와 같이, 통상 동합금재의 박판 시트를 프레스로 성형하여 제작되고, 구조-형상적으로는 기판에 고정되는 고정편과, 고정편에 대하여 구부림 성형되어 탄성적으로 변형하면서 접속부품의 배선과 접촉하는 접촉편으로 이루어진다. 그리고, 상기 종래의 컨택트 단자에서 접촉편은 고정편에 대하여 탄성복원력을 가지도록 변형된 연결부로써 고정편에 대하여 연결된다. As disclosed in the following Patent Document 1, the contact terminal is formed by molding a thin plate sheet of a copper alloy material into a press, and has a fixing piece to be fixed to the substrate in a structure-shape, And is made of a contact piece which contacts with the wiring of the connecting part while being deformed sexually. In the conventional contact terminal, the contact piece is connected to the fixing piece with a connection portion deformed to have an elastic restoring force with respect to the fixing piece.

KRKR 20-043594920-0435949 Y1Y1 이러한 종래의 컨택트 단자는 연결부에서 반복적으로 힘을 받으므로 일정 기간 사용하면 연결부에서 소성변형을 일으켜 탄성복원력을 잃어버림으로써 컨택트단자로서의 기능을 상실하게 된다. 이와 같이 컨택트 단자가 수명을 다하면, 컨택트 단자만을 교체할 수 없어 컨택트 단자가 설치된 커넥터 전체를 교체하여야 하는 문제를 야기한다.Such a conventional contact terminal receives repetitive force from the connecting portion, so that when used for a certain period of time, plastic deformation occurs at the connecting portion and the elastic restoring force is lost, thereby losing the function as a contact terminal. When the contact terminals reach the end of their service life, only the contact terminals can not be replaced, and thus the entire connector having the contact terminals must be replaced. 그리고, 컨택트 단자의 형상이나 구조가 복잡하게 설계되는 경우에 그 제조를 위한 금형이 복잡해져 제조원가가 상승하는 문제가 있으며, 특히 전자기기가 점차 박형화함에 따라 그에 내장되는 전기커넥터도 박형화 및 소형화되고, 그에 따라 컨택트단자의 크기도 소형화되는데, 컨택트 단자의 크기를 소형화하면 할수록 상기한 바와 같은 컨택트 단자의 소재 두께도 얇아지므로 연결부에서 탄성복원력도 그만큼 약해져 요구되는 탄성 접촉력을 얻을 수 없고, 뿐만아니라 수명도 단축되는 등 여러가지 문제를 가지고 있었다.In addition, when the shape and structure of the contact terminal are complicatedly designed, the mold for manufacturing the contact terminal is complicated and the manufacturing cost increases. Particularly, as the thickness of the electronic device gradually becomes thinner, the electrical connector embedded therein is also thinned and miniaturized, As the size of the contact terminal is miniaturized, the thickness of the material of the contact terminal becomes thinner as the above-mentioned size of the contact terminal becomes smaller. Therefore, the elastic restoring force also weakens so much that the required elastic contact force can not be obtained. There were various problems such as becoming.

이에 본 발명은 상기 종래의 컨택트 단자가 가진 단점을 해결하기 위하여 고안된 것으로, 장시간 사용에도 일정한 탄성복원력을 일정하게 유지할 수 있는 컨택트 단자를 제공함에 목적이 있다. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a contact terminal which is designed to solve the disadvantages of the conventional contact terminal and can maintain a constant elastic restoring force constantly for a long time.

또한 본 발명은 구조를 간단하게 하여 제조가 간편하고 제조원가를 절감할 수 있고, 박형 내지 소형의 커넥터에도 적용가능한 컨택트 단자를 제공함에 다른 목적이 있다. Another object of the present invention is to provide a contact terminal which is simple in construction and can be manufactured easily, can be manufactured at a low cost, and is applicable to a thin or small connector.

상기 목적을 달성하기 위한 본 발명은 컨택트 단자의 형상 대로 성형된 실리콘고무의 탄성 지지체와, 상기 탄성 지지체의 외측 표면에 전체적으로 또는 부분적으로 적층되어 결합된 도전체 박막을 포함한 것을 특징으로 한다. In order to accomplish the above object, the present invention is characterized by including an elastic support of silicone rubber molded in the shape of a contact terminal, and a conductive thin film laminated on the outer surface of the elastic support in whole or in part.

상기 도전체 박막은 탄성 지지체의 표면에 코팅된 동합금 또는 금 박막인 것을 특징으로 한다. The conductive thin film is a copper alloy or a gold thin film coated on the surface of the elastic support.

상기 도전체 박막은 탄성 지지체의 형상대로 동합금 또는 금으로 성형된 도전체 셀로 이루어져 탄성 지지체의 외측에 결합되는 것을 특징으로 한다. The conductive thin film is formed of a copper alloy or a conductive cell formed of gold according to the shape of the elastic support, and is coupled to the outside of the elastic support.

본 발명은 상기한 구성으로 되어, 실리콘고무로 된 탄성 지지체가 탄성복원력을 제공하므로 장시간 사용에도 일정한 탄성복원력을 일정하게 유지할 수 있어 제품수명 내지 내구성, 신뢰성을 증대시킬 수 있다. 또한 본 발명은 구성부품의 구조가 간단하여 제조가 간편하므로 제조원가를 절감할 수 있고, 조립생산성을 향상시킬 수 있다. 어떠한 사이즈의 커넥터에도 적용할 수 있다. According to the present invention, since the elastic support made of silicone rubber provides an elastic restoring force, the elastic restoring force can be constantly maintained even for a long period of time, so that the life, durability and reliability of the product can be increased. Further, the present invention can reduce the manufacturing cost and improve the assembly productivity because the structure of the component parts is simple and easy to manufacture. And can be applied to connectors of any size.
