Abstract: An electrical connector has a base, a first power terminal, a second power terminal, and multiple signal terminals. The base has a connecting portion having a flat face divided into a first region and a second region. The first and the second power terminals are disposed within the first region of the connecting portion. The multiple signal terminals are disposed within the second region of the connecting portion. At least one signal terminal is apart from the first power terminal by a first distance, and at least one of the other signal terminals is apart from the second power terminal by a second distance.
