For the purpose of attaining the above-mentioned object, a receptacle connector of the present invention is a receptacle connector used for an electrical connector configured to connect two circuit boards to each other. The receptacle connector comprises: a housing made of an electrically-insulating synthetic resin material, the housing including an upper wall, a lower wall, left and right sidewalls, the housing having a receiving space formed therein, the receiving space having an opening portion, through which a connection target is inserted, on a front side thereof; a plurality of contacts made of a metal material and arranged parallel to one another, the plurality of contacts including a plurality of signal line contacts and a plurality of ground contacts, and the plurality of contacts being placed with every two adjacent signal line contacts interposed between two ground contacts; a supporting member made of an electrically-insulating synthetic resin material, and configured to integrally support and fix thereto the plurality of contacts; and a common contact made of a conductive resin material and configured to electrically connect the a plurality of ground contacts together among the a plurality of contacts. The plurality of contacts are received in the receiving space of the housing, the plurality of contacts being integrated together by the supporting member, all the plurality of ground contacts among the plurality of contacts being electrically connected together by the common contact.
Because the first common contact 30 are formed in this manner, to the first common contact 30 can electrically connect together all of the plurality of ground contacts 20 a among the plurality of contacts 20 in the first row, and can resultantly equalize the electric potentials of each of the plurality of ground contacts 20 a.
In this embodiment, because the first common contact 30 of this kind is included therein, it is possible to prevent reduction in a shielding effect attributable to ground conductive lines in two connector regions of the plug connector and the receptacle connector 10 in this embodiment. Accordingly, crosstalk between the signal lines is reduced, and noise emission is prevented.
the common contact is configured to electrically connect a plurality of ground external contacts together among the plurality of external contacts, the plurality of ground external contacts corresponding to the plurality of ground contacts of the receptacle connector.
