High speed electrical connector and method of manufacturing same

An electrical connector, comprising:

• a terminal assembly consisting of a terminal module and a shielding housing, the terminal module comprising at least one conductive terminal and at least one insulator, wherein the at least one insulator is molded on the at least one conductive terminal and wraps around the at least one conductive terminal, wherein the shielding housing defines an accommodating cavity, wherein the terminal module is removably secured within the accommodating cavity;
• and
• a plastic housing defining a matching channel, wherein the shielding housing is removably secured within the matching channel and wherein a first material of the at least one insulator is different from a second material of the plastic housing.
