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. The second distance is larger than the first distance. Arrangement of the first power terminal, the second power terminal, and the multiple signal terminals prevents the first power terminal, the second power terminal, and the multiple signal terminals from interfering with one another. ## Claims ### Claim 1 An electrical connector comprising: a base having a connecting portion having a flat face divided into a first region and a second region;
