Description
본 고안은 무선전화기에 관한 것으로서, 특히 안테나와 무선전화기 본체에 설치된 인쇄회로기판간을 서로 연결시키고 외부의 충격에 의해서도 단락되지 않도록 보호하기 위한 안테나 접지장치에 관한 것이다.The present invention relates to a radiotelephone, and more particularly, to an antenna grounding device for connecting an antenna and a printed circuit board installed in a main body of a radiotelephone and protecting them from being shorted by an external impact.
통상적으로, 무선전화기에는 공중으로부터 각종 신호를 감지하기 위해 안테나를 구비한다.Typically, radiotelephones are equipped with antennas for sensing various signals from the air.
도 1은 종래 기술의 실시예에 따른 판스프링을 이용한 안테나 접지장치를 나타낸 단면 개략도이다.1 is a schematic cross-sectional view showing an antenna grounding apparatus using a leaf spring according to an embodiment of the prior art.
종래에는 도 1에 도시된 바와 같이 무선전화기의 커버(20)는 홀더 장착부(22)를 형성한다. 상기 홀더 장착부(22)는 커버의 일측 상단에서 내측에 구멍을 형성하고, 상기 홀더 장착부에는 안테나 홀더(12)가 장착된다. 상기 안테나 홀더(12)는 내부에 나사홈을 형성하고 있고, 상기 나사홈을 통해 안테나(도시되지 않음)의 일단이 삽입 설치된다.Conventionally, as shown in FIG. 1, the cover 20 of the radiotelephone forms a holder mounting portion 22. The holder mounting portion 22 forms a hole in the inner side at the upper end of the cover, the antenna holder 12 is mounted to the holder mounting portion. The antenna holder 12 has a screw groove formed therein, and one end of an antenna (not shown) is inserted and installed through the screw groove.
상기 안테나 홀더(12)의 일단 하측에는 판스프링(35)이 설치된다. 상기 판스프링은 일단이 곡면을 형성하여 안테나 홀더(12)의 일단과 접촉하고, 타단은 커버에 장착된 인쇄회로기판(30)과 납땜함으로써 결합된다.A leaf spring 35 is installed below one end of the antenna holder 12. One end of the leaf spring forms a curved surface and contacts one end of the antenna holder 12, and the other end is joined by soldering to the printed circuit board 30 mounted on the cover.
그러나, 사용자가 무선전화기를 사용하던 중 안테나에 외부의 충격이 가해지면, 그 충격은 안테나 홀더를 거쳐 판스프링에 전달된다. 충격을 받게 된 판스프링은 소성변형을 일으켜 상기한 안테나 홀더와의 접촉이 떨어지게 된다. 그러면, 안테나를 통해 입력되는 각종 신호들이 무선전화기의 인쇄회로기판까지 전달되지 못하므로 무선전화기는 통신장비로서의 기능을 상실하게 되는 문제점이 있었다.However, if an external shock is applied to the antenna while the user is using the wireless telephone, the shock is transmitted to the leaf spring via the antenna holder. The leaf spring subjected to the impact causes plastic deformation, which causes contact with the antenna holder. Then, since various signals input through the antenna are not transmitted to the printed circuit board of the wireless telephone, the wireless telephone loses its function as a communication device.
상기와 같은 문제점을 해결하기 위하여 본 고안의 목적은 안테나에 외부의 충격이 가해지더라도 안테나와 인쇄회로기판간의 접지를 견고히 유지할 수 있는 무선전화기의 안테나 접지장를 제공하는데 있다.In order to solve the above problems, an object of the present invention is to provide an antenna grounding field of a wireless telephone that can firmly maintain the ground between the antenna and the printed circuit board even when an external impact is applied to the antenna.
상기와 같은 목적을 달성하기 위하여 본 고안은 무선전화기에 있어서, 안테나 접지장치는 일측에 홀더 장착부를 형성한 커버와, 상기 홀더 장착부에 삽입 결합하고 중앙에 나사홈을 형성한 안테나 홀더와, 상기 커버의 내측에 설치된 인쇄회로기판과, 상기 인쇄회로기판에 일단이 지지결합하고 타단은 안테나 홀더의 하측면과 접촉한 코일 스프링으로 구성되는 것을 특징으로 한다.In order to achieve the above object, the present invention is a wireless telephone, the antenna grounding device is a cover having a holder mounting portion formed on one side, the antenna holder inserted into the holder mounting portion and formed a screw groove in the center, and the cover It is characterized in that the printed circuit board is installed in the inner side, and one end is coupled to the printed circuit board and the other end is composed of a coil spring in contact with the lower surface of the antenna holder.
