As shown in fig. 1 to 7, in the illustrated embodiment, the second housing 210 of the receptacle connector 200 includes an outer cylinder 211 and an inner cylinder 212 coaxial with the outer cylinder 211, and an elastic electromagnetic shield ring 240 is accommodated in a gap between the outer cylinder 211 and the inner cylinder 212. The first housing 110 of the plug connector 100 is adapted to be inserted into the gap and to radially compress the resilient electromagnetic shielding ring 240 so as to make electrical contact with the resilient electromagnetic shielding ring 240.

As shown in fig. 1-7, in the illustrated embodiment, the receptacle connector 200 further includes a second resilient seal 250, the second resilient seal 250 being received in the inner barrel 212 of the second housing 210 and being sleeved over the second insulator 220. The second elastic sealing member 250 is compressed between the inner surface of the inner cylinder 212 of the second housing 210 and the outer surface of the second insulator 220 to achieve sealing therebetween.

As shown in fig. 1 to 7, in the illustrated embodiment, the second terminals 230 of the receptacle connector 200 are adapted to be electrically connected to the circuit board 20, and the second housing 210 of the receptacle connector 200 is adapted to be fixed to the second panel 2.

As shown in fig. 1 to 7, in the illustrated embodiment, the receptacle connector 200 further comprises a second resilient sealing ring 204, the second resilient sealing ring 204 being adapted to be compressed between the second panel 2 and a second housing 210 of the receptacle connector 200 to effect a seal therebetween.

As shown in fig. 1 to 7, in the illustrated embodiment, external threads are formed on the outer wall of the second housing 210 of the receptacle connector 200, and screw holes are formed on the second panel 2, and the second housing 210 of the receptacle connector 200 is adapted to be screwed into the screw holes of the second panel 2.

As shown in fig. 1 to 7, in the illustrated embodiment, a ring of flange-shaped positioning portions 211c protruding outward is formed on the outer surface of the second housing 210 of the receptacle connector 200, a second seal ring positioning groove is formed on the flange-shaped positioning portion 211c, and the second elastic seal ring 204 is positioned in the second seal ring positioning groove and pressed between the flange-shaped positioning portion 211c and the second panel 2.

As shown in fig. 1-7, in the illustrated embodiment, the connector assembly further includes a third resilient sealing ring 105, the third resilient sealing ring 105 being compressed between the first housing 110 of the plug connector 100 and the second housing 210 of the receptacle connector 200 to effect a seal therebetween.

As shown in fig. 1 to 7, in the illustrated embodiment, a third seal ring positioning groove is formed on the outer surface of the first housing 110 of the plug connector 100, and a third elastic seal ring 105 is positioned in the third seal ring positioning groove and pressed between the outer surface of the first housing 110 and the inner surface of the second housing 210 to achieve sealing therebetween.

Fig. 8 shows a schematic view of a connector assembly according to another exemplary embodiment of the present invention.

In the embodiment shown in fig. 8, the second terminals 230 of the receptacle connector 200 are electrically connected to the circuit board 20, and the second housing 210 of the receptacle connector 200 is also fixed to the circuit board 20, rather than to the second panel 2.

As shown in fig. 8, in the illustrated embodiment, a second screw hole is formed on the second housing 210 of the receptacle connector 200, and a second connection hole is formed on the circuit board 20. The receptacle connector 200 further includes a second screw connector 201, and the second screw connector 201 passes through the second connection hole and is screw-coupled into the second screw hole, thereby fixing the second housing 210 to the circuit board 20.
