A terminal module is provided for use in an electrical connector. The module includes a plurality of conductive terminals arranged in a generally parallel side-by-side array. Each terminal includes a pair of opposite end sections. A pair of holding sections are located respectively adjacent to and inside the end sections. A central section is located between the holding sections. A dielectric plastic housing is overmolded about the holding sections leaving the opposite end sections exposed. The overmolded housing leaves a substantial portion of the central section exposed.
