2. Description of the Related Art In accordance with the demand for high-speed transmission and multi-polarization in computers, the impedance of transmission lines is matched,
There is an increasing demand for reducing signal reflection and crosstalk. 2. Description of the Related Art In computer printed circuit boards, signal lines are arranged on several planes, and grounds (and power supply lines) are arranged on other planes. Alternatively, a strip line structure is configured.

A connector used in a computer includes a jack connector attached to a printed circuit board and a plug connector connected to a coaxial cable. The plug connector is fitted into the jack connector. In such a connector, it is required to arrange more signal contacts compactly and to easily perform a wiring operation.

The ground shell is electrically connected to the ground contact of the plug connector. In the case of the jack connector, the ground shell is fitted to the insulating body, and the ground contact of the jack connector is electrically connected to the ground contact. Was not connected. Therefore, ground current passing through the ground shell did not flow from the plug connector side to the jack connector, and the effect of impedance matching was low.

An object of the present invention is to provide a jack connector with a ground shell so that the ground shell can be connected to the ground, and when the plug connector is fitted to the jack connector, the ground shell of the plug connector and the jack are connected. An object of the present invention is to provide a connector which can be easily and surely electrically connected to a ground shell of the connector. Another object of the present invention is to provide a jack connector provided with a ground shell that can be easily and reliably electrically connected to a ground shell of a plug connector. It is another object of the present invention to provide a plug connector in which more signal contacts can be arranged compactly and a wiring operation can be easily performed.
