Abstract

The present invention relates to a connection terminal for a mobile phone in which an elastic unit is formed in a dome shape to further increase the restoring force and to further slim a height. In the connection terminal for a mobile phone that a coupling unit coupled to a PCB of the mobile phone is formed and an elastic unit that an enclosure of the mobile phone is connected thereto is connected by a connection unit on top of the coupling unit, the connection terminal is a dome shape to increase the restoring force for the pressured applied to the bottom of the elastic unit and slim the connection terminal. Accordingly, the present invention has an effect of increasing the restoring force to the maximum by supporting the elastic unit and an auxiliary elastic unit since the support unit is in close contact with the coupling unit and the auxiliary elastic unit absorbs the pressure applied to the elastic unit to prevent deformation. In addition, the dome-shaped elastic unit and the auxiliary elastic unit are structured to maximize the restoring force, so that the dome-shaped elastic unit and the auxiliary elastic unit can effectively cope with continuous pressure, and the elastic force can be prevented from deteriorating due to the inflow or deformation of foreign substances, thereby ensuring an optimal connection state. In addition, by simply improving a shape of the elastic unit, the connection terminal can be made slimmer, and mass production is possible by molding with a mold, thereby reducing manufacturing cost and product cost and having a more economical effect.

에 관한 것으로, 더욱 상세하게는 탄성부를 돔(Dome) 형상으로 구성하여 복원력을 더욱 증대시키고 높이를 더욱As for, in more detail, by configuring the elastic part in a dome shape, the restoring force is further increased and the height is further increased.

슬림화한 휴대전화용 접속단자에 관한 것이다.It relates to a slim mobile phone connection terminal.

일반적으로 휴대전화용 접속단자는 휴대전화케이스에 장착된 안테나 또는 배터리와 같은 휴대전화 기구물과 휴In general, the connection terminal for a mobile phone is connected to a mobile phone device such as an antenna or battery mounted on a mobile phone case.

대전화의 보드가 전기적 접속을 할 수 있도록 하는 것이다. 이와 같은 휴대전화용 접속단자는 통상 보드에 실장This is to allow electrical connection to the board of the large phone. Such mobile phone connection terminals are usually mounted on the board.

되는 판상의 실장단자부와, 상기 실장단자부에서 경사지게 절곡된 접속가동단자부로 구성되어 있다.It is composed of a plate-shaped mounting terminal portion and a connection movable terminal portion bent obliquely at the mounting terminal portion.

[0003] 상기한 바와 같이 종래의 휴대전화용 접속단자는 휴대전화케이스에 장착된 안테나 또는 배터리와 같은 휴대전화[0003] As described above, the connection terminal for a conventional mobile phone is a mobile phone such as an antenna or a battery mounted on a mobile phone case.
