(4) the recessed portion F of the upper grounding piece 4' and the upper mask sheet 7 The abutting portion D is in contact with the recess portion F of the lower grounding piece 5' and the abutting portion D of the lower masking piece 8, and the arrangement of the recessed portion F increases the docking connector 100 The insertion and extraction force at the time of docking makes the docking connector 100 and the electrical connector 200 docked firmly, and is not easily loosened.

(5) the elastic portion 44 is movable in the hollow portion 115 and is electrically The connector 200 is abutted, and the hollow portion 115 provides a seating space for the elastic portion 44. When the electrical connector 200 abuts the elastic portion 44, the elastic portion 44 is resisted toward the orientation. The outer portion 115 is moved outside to facilitate insertion of the electrical connector 200 into the docking connector 100. When the electrical connector 200 is separated from the elastic portion 44, the elastic portion 44 returns to the initial state by its own elastic force. The position facilitates the electrical connector 200 to exit the docking connector 100.
