Description

  The present invention relates to a coaxial connector. In particular, the present invention relates to a structure of a small coaxial connector that can transmit a high-frequency signal from a coaxial cable to a printed circuit board, or can transmit a high-frequency signal from the printed circuit board to the coaxial cable, and is attached to a terminal of the coaxial cable.

  A portable electronic device that can be connected to the Internet, for example, a smartphone or a tablet PC, includes a coaxial connector for connecting a coaxial cable that transmits a high-frequency signal to a printed circuit board.

  Conventionally, such a coaxial connector is composed of a coaxial plug attached to the end of a coaxial cable and a receptacle mounted on a printed circuit board. By connecting the coaxial plug to the receptacle, a high frequency signal can be transmitted from the coaxial cable to the printed circuit board, or a high frequency signal can be transmitted from the printed circuit board to the coaxial cable.

  Generally, a coaxial cable is composed of a circular center conductor, a dielectric material such as a fluorine resin surrounding the periphery of the center conductor, an outer conductor such as a braided wire surrounding the periphery of the dielectric, and an insulating sheath covering and protecting the outer conductor. doing.

  For example, a conventional coaxial plug includes a metal shell and a cylindrical external contact. The coaxial plug also includes a housing and a center contact. The shell fixes the insulating sheath of the coaxial cable by crimping on one end side thereof. The shell and the external contact are integrally formed. The external contact is formed on one end side of the shell. The external contact is electrically connected to the external conductor of the coaxial cable.

  The housing electrically insulates the outer contact and the center contact. The center contact is disposed inside the external contact. The center contact includes a pair of leaf spring pieces configured in a bifurcated shape. When the center conductor of the coaxial cable is fitted between the pair of leaf spring pieces, the pair of leaf spring pieces sandwich the center conductor, so that the center conductor and the center contact can be electrically connected.

  When the coaxial plug is connected to the receptacle, the outer conductor can be connected to the outer contact of the receptacle and the central conductor can be connected to the central contact of the receptacle. And a high frequency signal can be transmitted to a printed circuit board from a coaxial cable, and a high frequency signal can be transmitted to a coaxial cable from a printed circuit board.

  By the way, the coaxial plug according to the prior art has only had the center conductor of the coaxial cable sandwiched between a pair of leaf spring pieces, so that the connection between the center conductor of the coaxial cable and the center contact is not reliable. Therefore, a coaxial plug in which the connection between the center conductor of the coaxial cable and the center contact is reliable is disclosed (for example, see Patent Document 1).

  On the other hand, the coaxial connector described above is required to be reduced in size and thickness as electronic devices using the same are reduced in size and thickness. In particular, the above-described coaxial connector is required to have a so-called low profile that reduces the mounting height on the printed circuit board. Due to such demands, a coaxial plug having a reduced height compared to a conventional coaxial plug has been disclosed (for example, see Patent Document 2).
