Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector for connecting coaxial cables to each other or to each other such as circuits and devices, and more particularly to a connector exhibiting excellent high frequency characteristics.

[0002]

2. Description of the Related Art As is well known, the recent development of electronic technology is remarkable, and the frequency of signals and the capacity thereof are increasing.

In such a connector used for high-frequency / high-speed transmission, it is necessary to strengthen the ground plane, that is, to surely dispose the ground layer, and a coaxial connector is a connector having a structure satisfying such requirements. Are known.

In the environment where such a coaxial connector is used, there is an increasing demand for higher quality of transmitted signals and reduction in size and weight of the apparatus. Along with this, the coaxial connector itself is required to be compact and have good electromagnetic characteristics, and various studies have been made on a connector structure that can satisfy the requirements.

[0005]

When the coaxial cables are connected to each other by such a coaxial connector, the adjustment of the characteristic impedance is relatively easy, so that no serious problem occurs. However, when connecting a printed wiring board or the like, which is a planar structure, to a three-dimensional object such as a coaxial cable, or when connecting printed wiring boards to each other, the coaxial connector used for such connection is electrically connected. There are still unsolved problems both structurally and structurally.

For example, in a vertical connection type connector used for connection between a coaxial cable and a printed wiring board and between printed wiring boards, high frequency characteristics can be improved by adjusting the pattern of the printed wiring board. While it is possible to keep it, the height of the connector from the printed circuit board becomes high and the space corresponding to it becomes necessary. That is, in the vertical connection type, while it is possible to maintain the electrical function of the connector, there is a mechanical structural problem.

In the surface mount type used for connecting the coaxial cable and the printed wiring board, the electrical structure of the connector portion is sacrificed in order to construct a low-profile connector, Impedance is disturbed and high frequency characteristics are deteriorated. That is, in the surface mount type, if mechanical requirements are met, a problem will occur in the electrical function of the connector.

The present invention solves the problems of the prior art and provides an alternative means to a thinner connector, in particular, a coaxial connector having a conventional structure, while maintaining good high frequency characteristics generally exhibited by the coaxial connector. The purpose is to provide.

A further object of the present invention is to provide a connector which can be easily connected in parallel when a printed wiring board is taken into consideration as an electric component of the other party.
