Connector assembly and method for manufacturing the same

A connector assembly comprising:

• a housing including:
• a plurality of accommodating grooves into which a plurality of terminals are inserted, respectively, and
• an insertion space recessed in a first direction intersecting a second direction in which the plurality of accommodating grooves extend, the plurality of accommodating grooves being formed in one surface of the housing;
• a terminal position assurance (TPA) mechanism inserted into the insertion space of the housing in the first direction, having a plurality of through-holes extending parallel to the plurality of accommodating grooves, and configured to inhibit the plurality of terminals inserted into the plurality of through-holes from being separated;
• joint terminals extending from an inside of the housing to the plurality of accommodating grooves, and electrically connected to the plurality of terminals inserted into the plurality of accommodating grooves;
• and
• at least one noise filter fixed to the housing or the TPA mechanism, and configured to enclose the plurality of accommodating groove of the housing, the plurality of through-holes of the TPA mechanism, or the joint terminals.
