Electrical connector and method thereof making the same

A sub-combination for mounting into an insulative housing comprising:

• a plurality of contact modules side by side arranged with one another in a transverse direction,
• each contact module including one row of contacts integrally formed, via insert-molding, within an insulator extending in a longitudinal direction perpendicular to the transverse direction, each contact including a main body with an opening extending therethrough in the transverse direction and coaxially aligned with corresponding opening formed in the insulator;
• and
• a plurality of assembling poles each extending along the transverse direction through the corresponding opening of the contact and the corresponding opening of the insulator of each contact module.

A method of making an electrical connector comprising steps of:

• forming a plurality of contact modules wherein each contact module includes one row of contacts integrally formed within an insulator via insert-molding, each insulator extends in a longitudinal direction and forms a plurality of through holes in a transverse direction perpendicular to the longitudinal direction;
• providing a plurality of assembling poles spaced from one another in the longitudinal direction, wherein each assembling pole extends in the transverse direction;
• and
• inserting the assembling poles through the corresponding through holes of said contact modules in an interference fit to form a sub-combination.
