A connector for connecting a connection partner with a board, the connector comprising a plurality of contact pairs, a plurality of ground contacts, a plurality of additional contacts other than the contacts of the contact pairs and the ground contacts, and an insulating housing holding the contact pairs, the ground contacts, and the additional contacts,
- wherein the connector has a first connection side for connection to the connection partner and a second connection side for connection to the board,
- wherein, on the first connection side, the ground contacts and contacts of the contact pairs are arranged in one row to form a contact array and the ground contacts are arranged between the contact pairs, respectively,
- wherein, on the second connection side, the ground contacts are arranged in a first row so as to be spaced apart from each other in a first direction, while two of the contact pairs, which are arranged on both sides of each of the ground contacts on the first connection side, are arranged in a second row and a third row, respectively, which are located on both sides of the first row in a second direction perpendicular to the first direction, the contacts of the contact pairs being displaced from the ground contacts in the first direction, and
- wherein the additional contacts each have a connecting portion located on the second connection side, a holding portion located away from the connecting portion, an intermediate portion located between the connecting portion and the holding portion, and a bent portion bent between the holding portion and the intermediate portion, and wherein the housing comprises a holding member integrally holding the holding portions by insert molding, a locator for positioning the holding member on the second connection side, and a dielectric covering the intermediate portions in a contact manner and coupled to the locator.
