In such a connector, the plug connector and the receptacle connector to which the plug connector is combined constitute one assembly. The plug connector and the receptacle connector are each provided with a plurality of terminals connected to each other to transmit electrical signals. Korean Patent Laid-Open Publication No. 2012-0103489 discloses a conventional receptacle terminal. The receptacle connector 1 according to the related art includes a plurality of (parallel) terminals 2. However, this is simply arranged in one row (column) without considering the electrical characteristics of the terminals 2, and in particular, when the number of the terminals 2 increases, the width of the receptacle connector 2 is increased There is a concern that the electrical characteristics may deteriorate due to a decrease in the distance between the terminals 2 and the like. When the (parallel) terminals 16 of the plug connector 31 to be coupled with the receptacle connector 1 are connected to the board, a number of patterns corresponding to the number of the terminals 16 are formed on the board. Therefore, when the spacing between the patterns is maintained for workability or the like, the width of the substrate is increased and the spacing between the patterns is decreased in order to keep the width of the substrate constant.
