Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

The present invention relates to an electrical contact terminal, and more particularly, to an electrical contact terminal, in which the elastic moving part is operated in a diagonal direction while lowering the total height, thereby maintaining or increasing the moving distance of the elastic moving part, To an electrical contact terminal.

Generally, in order to maintain an electrical connection state between a conductor and a conductor, a predetermined electrical contact terminal is provided between the conductor and the conductor so that an electrical connection state between the conductor and the conductor is maintained by the electrical contact terminal.

Such an electrical contact terminal is mainly used for electrically connecting an antenna to a printed circuit board by being installed in an electronic device such as a smart phone or a tablet.

1 is a view showing a state where a conventional contact terminal is interposed between a first conductor and a second conductor.

1, the conventional electric contact terminal 100 includes a fixed plate 110 having one side contacting one side of the first conductor P1, and a resilient force generating member 110 extending upward from one end of the fixed plate 110. [ The elastic contact portion 130 extends in the direction of the fixed plate 110 from the main body 120 and the elastic force providing portion 120 and has elasticity and one side is curved upward to contact one side of the second conductor P2. .

In the conventional electrical contact terminal 100, the elastic contact part 130 is elastically contacted with the second conductor P2 in the state of having the elastic force in the vertical direction by the extension part 120, Two conductors P2 are electrically connected to each other.

In recent years, as the size of electronic devices has become very small, the conventional electrical contact terminal 100 has been required to be miniaturized in order to minimize the contact resistance between the fixing plate 110, the elasticity providing unit 120, And the elastic contact portion 130 must be formed at a predetermined height. However, the conventional electrical contact terminal 100 has a limitation in lowering the overall height while maintaining the reliability of contact with the conductors.

In recent years, efforts have been made to lower the overall height while maintaining the reliability of contact with the conductors.

For example, in Korean Patent Laid-Open Publication No. 2011-0090077 and US 7364477, a hole is formed in a printed circuit board, and an electrical contact terminal is inserted into a hole of a printed circuit board to lower the overall height while maintaining electrical contact reliability Korean Unexamined Patent Publication No. 2001-009077 and U.S.P. No. 7364477 additionally require fixation for forming a hole in a printed circuit board, thereby lowering the productivity and increasing the manufacturing cost and decreasing the durability of the printed circuit board A new problem has arisen.

As another example, Korean Patent No. 122242 proposes an electrical contact terminal having a shape of 'r', and the reliability of contact with the conductors can be improved through the two elastic portions. However, in the above-mentioned Korean Patent No. 1222242, Since the terminal is formed in a laminated shape of three plates, the height is basically formed to be high according to the thickness of the material. In addition, since the height of the two elastic portions increases the height, the problem of the conventional electric contact terminal is solved There were limits to doing so.
