Connector having improved releasing mechanism

An electrical connector assembly comprising:

• a metallic cage including two opposite primary walls in a vertical direction and two opposite side walls in a transverse direction perpendicular to said vertical direction to commonly define an elongated rectangular receiving space having an opening in a front end region;
• a complementary receptacle connector located around a rear end region of the receiving space opposite to said front end region in a front-to-back direction perpendicular to both said vertical direction and said transverse direction;
• one of said opposite primary walls defining around the front end region thereof a locking tang with a locking hole therein;
• an electrical connector unit including two opposite primary faces and two opposite side faces to commonly define an elongated rectangular body in essentially snug compliance with the receiving space so as to be adapted to be inserted into the receiving space via the opening;
• a cable linked to a rear end section of the connector unit;
• a resilient arm formed on one of the two opposite primary faces and located around the rear end section with thereof a locking tab compliant with the locking hole;
• and
• an operator associated with the resilient arm around the rear end section to actuate the resilient arm to move;
• wherein
• when the electrical connector unit is assembled into the receiving space via the opening, the resilient arm is protectively hidden in the cage and located behind the opening to have the locking tab received in the locking hole while the operator is exposed outside of the cage and intimately located in front of the opening for good accessibility and easy operation.

An electrical connector assembly adapted to be received in a cage which defines a locking tang on a front end region and equipped with a receptacle connector on a rear end region opposite to the front end region in a front-to-back direction, comprising:

• an elongated rectangular body having two opposite primary faces in a vertical direction perpendicular to said front-to-back direction and two opposite side faces in a transverse direction perpendicular to both said front-to-back direction and said vertical direction;
• a printed circuit board disposed in the rectangular body with a mating edge exposed at a front end section of the rectangular body for mating with the receptacle connector;
• a cable linked to a rear end section of the rectangular body;
• and
• a resilient arm associated with one of the two opposite primary faces around the rear end section and adapted for being aligned with the locking tang, and equipped with a triangular locking tab thereon for engagement within the locking hole;
• wherein
• an operator is associated with the resilient arm to actuate the resilient arm to move for disengaging the locking tab from the locking hole.
