The latching portion 602 of the latching member 60 is fastened into the latching slot 121 of the body 1 and extends into the latching hole 411 of the terminal block 4 . Thus, the body 1 and the terminal block 4 are positioned together by the locking member 6.

Referring to the first figure and the seventh to ninth figures, when the electrical connector assembly 100 of the present invention is not docked with the mating connector, the slider 2 is received by the receiving member 10 of the body 1 under the thrust of the elastic member 5 and The front surface abuts against the docking port 110 of the body 1 to close the through slot 120 of the arms 12 on both sides of the body 1 and the upper surface of the body 1. The cavity 21 on the front surface of the slider 2 forms a receiving space with the docking port 110 of the body 1. The cavity, the receiving cavity and the electrical connector combination are not in communication with each other, so that external dust and moisture cannot enter the electronic device through the through slot 120 and the receiving cavity 10 to achieve dustproof and waterproof effects. When the electrical connector assembly 100 of the present invention is docked with the docking connector, the docking connector can easily enter the cavity 21 of the slider 2 and apply a thrust to the slider 2 to slide back and compress the elastic member 5, the slider 2 The rear surface will abut against the front surface of the base portion 41 of the terminal block 4. At this time, the tongue portion 42 of the terminal block 4 is placed above the second surface 202 of the slider 2 and is stopped by one step of the slider 2. The portion of the U-shaped bent portion 311 of the terminal 3 protruding from the base portion 41 is pressed by the slider 2 to move the contact portion 32 of the terminal 3 downward and pass through the front end portion of the terminal slot 2010 to enter the receiving cavity 10 and press and dock A terminal (not shown) in the connector, so that the contact holding force between the terminal 3 and the terminal on the mating connector is sufficiently large to ensure stable signal transmission. When the slider 2 moves backward, the locking portion 62 holds the side surface of the mating connector plug portion, so that the buckle between the electrical connector assembly 100 and the mating connector is completed, and the docking port 110 of the body 1 is docked. The device is blocked so that dust or moisture cannot enter.

Referring to the fifth and sixth figures, when the electrical connector assembly 100 of the present invention is in an unused state, the resilient member 5 applies the forward thrust of the slider 2 and holds the slider 2 to the original position. The front end of the slider 2 extends to the docking port 110 of the body 1, and the plurality of ribs 1101 of the docking port of the body 1 are engaged in the plurality of terminal slots 2010 of the slider 2. The terminal 3 is in a state where no force is applied.

Referring to the tenth through twelfth drawings, a second embodiment of the electrical connector assembly 100' of the present invention is distinguished from the first embodiment in that it also adds a spacer 7 structure. The spacer 7 is a thin rectangular parallelepiped or is provided in other shapes as needed. The spacer 7 is located below the slider 2, and its upper surface is attached to the lower surface of the slider 2. The spacer 7 is received in the receiving cavity 10 of the body 1 together with the slider 2, and the contact force between the slider 2 and the body 1 is increased. At the same time, after the assembly, the compressibility of the spacer 7 is utilized, and the spacer 7 and the slider 2 are used. The upward force is generated to fill the assembly gap and provide a better waterproof level, thereby better isolating the internal and external space of the electrical connector assembly 100', and the dustproof and waterproof effect is more obvious.
