Electrical connector assembly

An electrical connector assembly, comprising:

• an electrical connector, including:
• a first main module;
• a plurality of first terminals fastened in the first main module;
• a first shell mounted around an outer surface of the first main module;
• and
• a protective tube mounted around an outer surface of the first shell, an outer surface of the protective tube protruding outward to form a mounting portion, one end of the mounting portion being defined as a first position, and the other end of the mounting portion being defined as a second position, an inner surface of the protective tube having a guiding groove, the mounting portion defining a sliding groove penetrating through a rear surface of the mounting portion, a front of an inner wall of the sliding groove defining a perforation penetrating through the inner wall of the sliding groove in a radial direction of the protective tube, a rear of the inner wall of the sliding groove having a step, the sliding groove and the guiding groove being communicated through the perforation;
• a locking structure disposed to the mounting portion, a front of an inner surface of the locking structure protruding towards the first shell to form a location foot, a rear of the inner surface of the locking structure protruding downward, then slantwise extending rearward and downward, and further extending rearward to form an abutting portion;
• and
• a docking connector docked with the electrical connector, the docking connector including:
• a second main module;
• a plurality of second terminals fastened in the second main module;
• and
• a second shell mounted around an outer surface of the second main module, the second shell having a protrusion, the protrusion being inserted in the guiding groove;
• wherein when the protective tube of the electrical connector is rotated, the protrusion slides along the guiding groove, the protrusion slides from a front end of the guiding groove to a rear end of the guiding groove, so the electrical connector is locked with the docking connector for a first time, the electrical connector assembly is in a first locking status, the locking structure is located at the first position, the abutting portion abuts against the step, the location foot faces the inner wall of the sliding groove;
• and
• wherein when the locking structure moves from the first position to the second position, the abutting portion is separated from the step, the location foot moves to the perforation, and the location foot abuts against the protrusion of the docking connector, so the electrical connector is locked with the docking connector for a second time.

• a locking structure disposed to the mounting portion, the locking structure having a main body, the main body extending downward and expanding outward to form a lower portion, the lower portion being disposed in the sliding groove, a front end of an inner surface of the lower portion extending towards the first shell to form a location foot, a rear end of a bottom surface of the main body protruding downward, then slantwise extending rearward and downward, and further extending rearward to form an abutting portion;
• and
• a docking connector docked with the electrical connector, the docking connector including:
• a second main module;
• a plurality of second terminals fastened in the second main module;
• and
• a second shell mounted around an outer surface of the second main module, the second shell having a protrusion, the protrusion being inserted in the guiding groove;
• wherein when the protective tube of the electrical connector is rotated, the protrusion slides along the guiding groove, the protrusion slides from a front end of the guiding groove to a rear end of the guiding groove, so the electrical connector is locked with the docking connector for a first time, the electrical connector assembly is in a first locking status, the locking structure is located at the first position;
• wherein when the locking structure is located at the first position, the abutting portion abuts against a rear end of the first platform of the mounting portion, the location foot abuts against the second platform of the mounting portion;
• and
• wherein when the locking structure moves from the first position to the second position, the abutting portion abuts against a front end of the first platform of the mounting portion, the location foot moves away from the second platform, the location foot moves to the perforation, and the location foot abuts against the protrusion of the docking connector, so the electrical connector is locked with the docking connector for a second time, the electrical connector assembly is in a second locking status.
