Similarly, corresponding to the second electrical specification, among the fixing portions 22 arranged along the first direction L1, at least one shielding terminal, functional terminal or / and a power terminal fixing portion 22 is disposed between the fixing portions 22 of the two differential signal terminal pairs. Since the electrical connection portions 23 correspond to the fixing portions 22 one-to-one, at least one shielding terminal, functional terminal or / and a power terminal electrical connection portion 23 is disposed between the electrical connection portions 23 of the two differential signal terminal pairs. This plays the role of electromagnetic shielding and can prevent crosstalk between the differential signal terminal pairs.
