Intermediate electrical connector, electrical connector assembly, and electrical connector assembly equipped with a circuit board

An electrical connector assembly, comprising:

• an intermediate electrical connector which, upon connection of a first counterpart connect body and a second counterpart connect body each from different sides in a manner permitting plugging and unplugging, mediates between the first and second counterpart connect bodies, and which comprises:
• terminals that are enabled to contact, respectively, the first counterpart connect body and the second counterpart connect body;
• a housing that directly or indirectly secures the terminals in place;
• and
• locking fittings supported by the housing of the intermediate electrical connector, the locking fittings comprising locking portions enabled to engage lockable portions provided in said first counterpart connect body in a direction of disengagement when the intermediate electrical connector and the first counterpart connect body are connected,
• wherein the housing comprises an upper housing and a lower housing coupled by the locking fittings, and
• wherein a part of the locking fittings that retains the upper housing and the lower housing extends to a location of the first counterpart connect body to lock the intermediate electrical connector into the first counterpart connect body.

An intermediate electrical connector which, upon

• connection of a first counterpart connect body and a second counterpart connect body each from different sides in a manner permitting plugging and unplugging, mediates between the first and second counterpart connect bodies, and which comprises:
• terminals that are enabled to contact, respectively, the first counterpart connect body and the second counterpart connect body;
• a housing that directly or indirectly secures the terminals in place;
• and
• locking fittings supported by the housing of the intermediate electrical connector, the locking fittings comprising locking portions enabled to engage lockable portions provided in the first counterpart connect body in a direction of disengagement when the intermediate electrical connector and the first counterpart connect body are connected,
• wherein the intermediate electrical connector comprises a plurality of connecting units having the terminals and the housings,
• wherein the plurality of connecting units are arranged such that an array direction is a direction perpendicular to a direction of connection to the first connect body, and
• wherein the locking fittings extend throughout an array range of the plurality of connecting units in the array direction and collectively couple said plurality of connecting units.
