The conductive terminals 12 include, but are not limited to, signal terminals, power terminals, and ground terminals. The conductive ring 2 is sleeved on the lower end of the insulating housing 11, and the conductive terminals 12 extend from the lower portion of the conductive ring 2 to be inserted into or welded to corresponding electrical contacts of the circuit board 200, so that the conductive ring is electrically connected to the ground contact of the circuit board.
In an exemplary embodiment, the electrical connector 100 further comprises a plurality of elastic conductive means 3, and the elastic conductive means 3 is mounted on the conductive ring 2 and elastically protrudes from an upper portion of the conductive ring 2 to allow the elastic conductive means 3 to be electrically connected with the ground contact of the circuit board 200. Thus, as shown in fig. 4 and 5, when the electrical connector is mounted on the conductive frame 300, the elastic conductive means 3 is compressed by the conductive frame 300, so that the elastic conductive means 3 is reliably electrically connected with the mounting seat of the electrical connector.
In an exemplary embodiment, the conductive loop 2 includes: a mounting ring 21 sleeved on the lower end of the insulating shell 12; and a pair of mounting seats 22 arranged on the outer portions of two opposite sides of the mounting ring 21, wherein the two elastic conductive devices 3 are respectively mounted on the mounting seats 22 and electrically connected with the mounting seats 22. As shown in fig. 4 and 5, the mount is adapted to be electrically connected with a ground contact of the circuit board 200, so that the elastic conductive means 3 is electrically connected with an electrical contact of the circuit board 200.
In an exemplary embodiment, as shown in fig. 3, said elastic conductive means 3 are made of sheet metal, for example copper or a copper alloy, and comprise: two opposite connection ends 32 connected to the mounting seat 22; and an arch 31 between the two connection ends 32.

In one embodiment, the mount 22 includes: one body portion 221 mounted to the outside of the mounting ring 21, and two positioning portions 223 mounted to the outside of the mounting ring 21 on the upper portion of the body portion 221. Two positioning portions 223 are located at both ends of the main body portion 221, and the connection end 32 of the elastic conductive device 3 is positioned in the gap 222 between the two positioning portions 223 and the main body portion 221. Thus, when the elastic conductive device 3 is pressed by the conductive frame 300, the connection terminal 32 moves in the gap 222 relative to the body 221 in accordance with the deformation of the arch portion 31.
In one embodiment, the gap 222 has a circumferential opening towards the outside in the circumferential direction, such that the mounting end 32 of the elastic conductive means 3 elastically protrudes out of the circumferential opening.
Further, the gap 222 has a radial opening facing outward in the radial direction, so that the mounting end 32 of the elastic conductive means 3 is mounted into the gap 222 through the radial opening. In this way, the connection end 32 of the elastic conductive means 3 can be easily fitted into the gap 22.
Fig. 6 shows a perspective view of an electrical connector according to another exemplary embodiment of the present invention.

That is, in the electrical connector of the embodiment of fig. 6, without providing the above-mentioned radial opening, the dome 31 can be gripped so that it is inwardly contracted, after which the two connection terminals 32 are inserted into the channels 222' at the opposite inner sides of the two gaps 222, and then the dome 31 is released, thereby mounting the elastic conductive means 3 on the mount 22. The other structure for the electrical connector shown in fig. 6 is the same as the electrical connection shown in fig. 1. And will not be described in detail herein.
