【Detailed ways】

Referring to FIGS. 1 to 2 , the electrical connector 100 includes a shielding case 1 , an insulating body 2 , a plurality of conductive terminals 3 assembled in the insulating body 2 , and a dustproof cover 4 .

The shielding housing 1 includes a top wall 11, a bottom wall 12 opposite to the top wall 11, and a pair of side walls 13. Each wall surrounds and forms a receiving cavity 14 and a docking port 17. The front half 111 of the top wall 11 is larger than the rear half 112. high. The insulating body 2 includes a base portion 21 and a docking portion 22 extending forward from the base portion 21 . The upper and lower surfaces of the docking portion 22 are provided with terminal grooves 221 , and the docking portion 22 is accommodated in the aforesaid receiving cavity 14 . The conductive terminal 3 includes a holding part 31, a contact part 32 extending forward from the holding part 31 and a tail part 33 extending backward from the holding part 31. The holding part 31 is held in the base part 21 of the insulating body 2, and the contact part 32 is located on each terminal The contact portion 32 is in the slot 221 , and the contact portion 32 is exposed on the upper and lower surfaces of the docking portion 22 , and the tail portion 33 extends out of the base portion 21 for soldering to a circuit board (not shown).

Please refer to FIG. 2 to FIG. 5 , the dustproof cover 4 is made of metal material, it is rotatably disposed at the docking port 17 of the shielding case 1 , and is pivotally connected with the two side walls 13 of the shielding case 1 . A pair of positioning holes 131 are provided at corresponding positions on the upper ends of the two side walls 13 of the shielding case 1. The dustproof cover 4 includes a cover body 42 covering the docking port 17 and a rotating shaft 41 extending outward from the top ends of the cover body 42. , The rotating shaft 41 at one end of the cover body 42 is provided with an elastic member, and the elastic member is located in the receiving cavity 14 . In this embodiment, the elastic member is a torsion spring 5 . The rotating shaft 41 at one end of the cover body 42 is longer than the rotating shaft 41 at the other end, and the longer rotating shaft 41 is provided with a compressible torsion spring 5 . When installing the dust cover 4, the rotating shaft 41 sleeved with the torsion spring 5 is first inserted into the corresponding positioning hole 131, and then the torsion spring 5 is compressed, so that the rotating shaft 41 at the other end is inserted into the other side wall In the positioning hole 131 of 13, the torsion spring 5 is connected to one side of the cover body 42 and the corresponding side wall 13, and the cover body 42 hangs down in the vertical direction. Since the dust-proof cover 4 is made of metal material, while preventing dust from entering the electrical connector 100 , static electricity generated during the docking process can be better eliminated, and the dust-proof cover 4 has a simple structure and is easy to manufacture.
