Detailed Description

Fig. 1-3 show a plug connector 100 and a mating receptacle connector 8. The plug connector 100 includes an insulative housing 1, a resilient clip 2, and a blocking member 112. As shown in fig. 1, 3 and 5, the insulating housing 1 has an adapting plate 113 and a receiving groove 115 on the top surface of the adapting plate 113. The elastic fastener 2 includes a fixing portion 21 and a pressing portion 20 connected to the fixing portion 21. As can be seen from fig. 3, 5 and 6, the fixing portion 21 is provided on the adaptation plate 113. The pressing portion 20 is located above the fixing portion 21, and the pressing portion 20 includes a pressing end 24 suspended in the air and at least one fastening block 25 located between the fixing portion 21 and the pressing end 24. The stopper 112 is connected to the insulating housing 1 and spans over at least a portion of the pressing portion 20 of the elastic fastener 2. In other embodiments, the height of the barrier 112 is greater than or equal to the height of the elastic fastener 2 (or the pressing end 24). In addition, the blocking member 112 is also located between the pressing end 24 of the elastic fastener 2 and the button 25.

The plug connector 100 uses the blocking member 112 to provide a protection structure for the pressing portion 20, which reduces the probability of foreign objects directly touching the pressing portion 20. For example, foreign objects traveling in a direction a or B (see fig. 7) will be blocked by the blocking member 112 and will not directly collide with the pressing end 24, thereby reducing the probability of touching the pressing end 24 by mistake and reducing the probability of deformation or damage of the pressing end 24 due to collision of foreign objects. If the foreign object travels along the direction C and collides with the pressing portion 20, the pressing portion 20 may be blocked by the blocking member 112 to avoid damage due to excessive deformation (e.g., excessive upward tilting).

As shown in fig. 1 to 3, the insulating housing 1 further includes a first housing 11, a second housing 12, and a rear cover 14. The first housing 11 includes two

The first protrusions 144 are located on the two arms 143, and when the rear cover 14 is inserted into the second cavity 110b, the first protrusions 144 are correspondingly fixed to the corresponding first openings (or slots) 117, and the arms 143 of the rear cover 14 are abutted against the notches 121 of the second housing 12. The channel 141 is located within the bump 142 and the channel 141 has two openings 145 located on two sides of the bump 142, respectively, which are adjacent.

As shown in fig. 3 and fig. 5 to 8, the pressing portion 20 of the elastic fastener 2 further includes at least one bending portion 221, a first inclined portion 22 and a second inclined portion 23. The bending portion 221 is connected between one end of the fixing portion 21 and one end of the pressing portion 20. The other ends of the pressing portion 20 and the fixing portion 21 extend in substantially the same direction. The second inclined portion 23 extends upward and rearward from the first inclined portion 22. The pressing end 24 extends upward and rearward from the second inclined portion 23 to a position higher than the first housing 11. The pressing end 24 may also be higher than the stop 112 located behind the button 25. The catch 25 is located on the top surface of the first inclined portion 22 and is exposed to the window 111 of the first housing 11.

When the fixing portion 21 of the elastic fastener 2 is fixed in the receiving groove 115 of the insulating housing 1, at least one protruding point 119 in the receiving groove 115 catches or blocks the rear end of the fixing portion 21. At least one restriction portion 26 of the first inclined portion 22 presses against a supporting portion 119a (or the top plate 103) of the stopper 112, thereby forming a gap 119b between the first inclined portion 22 and the stopper 112. In this embodiment, the support 119a extends from the bottom of the stopper 112.

As shown in fig. 1, a peg 82 of the receptacle connector 8 has at least one hole 84. When the plug connector 100 is inserted into the receptacle connector 8, the catch piece 25 of the elastic catch piece 2 is inserted into the hole 84 of the latch 82, and the elastic catch piece 2 is locked to the latch 82 of the receptacle connector 8. When the pressing end 24 of the elastic fastener 2 is pressed by the user to move downward, the first inclined portion 22 of the elastic fastener 2 moves downward along with the pressing end 24, so that the fastening block 25 on the first inclined portion 22 is separated from the hole 84 of the latch 82, and the elastic fastener 2 is unlocked from the latch 82 of the socket connector 8.
