  In recent years, with this type of connector, the demand for further miniaturization has become stronger along with the miniaturization of electronic devices. However, as the connector size becomes smaller, the distance between contacts is also narrowed and generated between contacts. The problem of noise such as crosstalk becomes remarkable. When miniaturizing the connector in this way, it is impossible to secure a sufficient number of ground connection points between the shell member of the plug connector and the shield member of the receptacle connector, and noise interference can be prevented appropriately.

Therefore, it is possible to connect the ground between the contacts without separately providing a shield member on the receptacle connector side, and the noise reduction effect is sufficiently achieved while reducing the number of parts and downsizing compared to the case where the shield member is provided. This makes it possible to improve the signal transmission performance of the connector. Furthermore, since a part of the plurality of plug-side contacts can be grounded with a simple configuration in which a part of the plurality of plug-side contacts is joined to the shell member and the corresponding receptacle-side contact is connected to the ground terminal on the substrate, As a trend toward miniaturization of the connector, it is possible to realize a low-profile design of the connector and a demand for narrowing the contact arrangement pitch while ensuring a sufficient number of ground connection points.
