Detailed Description
The present invention will be described in further detail below with reference to specific embodiments and with reference to the attached drawings. In the present embodiment, the direction in which the plug connector is inserted into the receptacle connector is defined as "right", and the opposite direction is defined as "left".
Referring to fig. 1 and fig. 3, compared with the conventional plug connector, the improvement of the novel plug connector of the present invention is: the inner wall of the coupling nut 102 is additionally provided with a second boss 1021, and the second boss 1021 is positioned at the left side of a first boss 1011 convexly arranged on the outer wall of the spline housing 101.
