In a multipolar connector for high-speed differential signal transmission, when differential signal terminals and other terminals (for example, external terminals such as power supply terminals and ground terminals (i.e., terminals other than the paired terminals)) are arranged at equal pitches, a coupling force between differential pairs cannot be sufficiently secured, and a transmission mode is relatively close to a single mode. In the single mode transmission, the signal speed, skew, noise and other characteristics are inferior to those of the differential mode transmission, and if the pitch is simply reduced to enhance the coupling force, the impedance is too low with respect to the impedance set or the rated value by the influence of other terminals, and thus it is difficult to realize the differential mode transmission at the equal pitch in the connector section of the 100Q series of differential impedance, and the conventional technology can enhance the coupling force between the differential pairs and reduce the influence from other terminals by changing the width of the differential signal terminals or bending the differential signal terminals so that the pitch interval between the contact portions connected to the mating terminals of the differential signal terminals is narrower than the pitch interval between the contact portions of the differential signal terminals and the contact portions of other terminals adjacent to the differential signal terminals, therefore, there is a concern that impedance is discontinuous due to uneven intervals between differential pairs, which may affect signal quality, and when a stage formed of an insulating material and a terminal are integrated by insert molding, there is a problem that it is difficult to fabricate an analog due to non-uniform terminal shapes, and it is difficult to ensure accuracy.
