(61) (2) The first terminal set 20 and the second terminal set 40 are symmetrical along the longitudinal axis L. The relative position between the first terminal set 20 and the second terminal set 40 on a left side of the longitudinal axis L corresponds to the relative position between the first terminal set 20 and the second terminal set 40 on a right side of the longitudinal axis L. Therefore, structures of molds of the terminals are simplified.

(62) (3) The first soldering sections 22 and the second soldering sections 42 are arranged in a row. Thus, a length of the electrical receptacle connector and a length of a circuit board that is mounted on the instant disclosure are reduced. Then, the dimensions of the connector of the instant disclosure and the dimensions of the circuit board are reduced.

(63) Even though numerous characteristics and advantages of the instant disclosure have been set forth in the foregoing description, together with details of the structure and features of the invention, the disclosure is illustrative only. Changes may be made in the details, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
