[0079] The application does not make specific limitation on the structure of the conductive part 6, preferably, referring to Figure 8 and Figure 9 , the conductive part 6 includes a conductive plate 61, an elastic arm 62 arranged on the conductive plate 61, and a conductive arm 63 arranged on the conductive plate 61, one end of the elastic arm 62 away from the conductive plate 61 forms a contact end, and the elastic arm 62 has a connecting end connected to the conductive plate 61, the contact end can elastically swing around the connecting end, so that the contact end can keep in contact with the shielding ring 4.
[0080] After the shielding ring 4 is installed inside the shell 2, the elastic arm 62 contacts the shielding ring 4, and since the elastic arm 62 can elastically swing around the connecting end, the elastic arm 62 can be elastically adjusted to ensure that the elastic arm 62 can always contact the shielding ring 4, thereby ensuring the electrical conductivity between the conductive part 6 and the shielding ring 4, and after the via connector is installed on the case of the equipment, the conductive arm 63 contacts the case of the equipment, so that the conductive part 6 keeps in contact with the case.
[0081] Further, referring toFigure 7 The front cover 5 is provided with an extension slot 52 for the extension of the conductive arm 63, and the inside of the front cover 5 is provided with a support rib 53 extending inwardly from the front end wall of the front cover 5, the support rib 53 is located at the inner side of the conductive plate 61 to support the conductive part 6, and the inside of the front cover 5 is provided with a stop rib 54 which can be stopped with the conductive plate 61 to limit the movement of the conductive plate 61 towards the rear end of the front cover 5.
[0082] It should be noted that the "support rib 53 extending inwardly from the front end wall of the front cover 5" mentioned above refers to the support rib 53 extending from the front end wall of the front cover 5 to the rear end of the front cover 5 along the axial direction of the front cover 5.
[0083] Since the front cover 5 is provided with an extension slot 52 for the extension of the conductive arm 63, the conductive arm 63 can extend through the extension slot 52 and abut against the case of the equipment; since the inside of the front cover 5 is provided with a support rib 53 extending inwardly from the front end wall of the front cover 5, the installation mode of the conductive part 6 is inserted from the rear end to the front end of the front cover 5, which reduces the installation difficulty of the conductive part 6, and the support rib 53 is located at the inner side of the conductive plate 61, so that the support rib 53 can support the conductive plate 61 to increase the stability of the conductive plate 61; at the same time, since the inside of the front cover 5 is provided with a stop rib 54 which can be stopped with the conductive plate 61, the movement of the conductive plate 61 can be limited by the stop of the stop rib 54 and the conductive plate 61, so as to avoid the phenomenon that the conductive plate 61 may be separated from the front cover 5 after being installed in place, thereby further increasing the connection stability of the conductive part 6 and the front cover 5.

[0085] Since the stop arm 611 is bent towards the outside of the front cover 5, after the conductive part 6 is installed in place, the stop arm 611 can exert a force on the conductive plate 61 towards the inside of the front cover 5, so that the support rib 53 abuts against the conductive plate 61, to avoid the phenomenon that the conductive plate 61 can shake relative to the front cover 5 due to the gap between the conductive plate 61 and the support rib 53, thereby improving the fixing effect of the conductive part 6.
[0086] Preferably, the conductive arm 63 is arranged on one side of the conductive plate 61 close to the front end of the front cover 5, and the conductive arm 63 is bent from the front end to the rear end of the conductive plate 61, so that the conductive arm 63 can be elastically deformed to ensure the contact effect of the conductive arm 63 with the case, and the stop arm 611 is arranged opposite to the conductive arm 63.

[0090] Since the diameter of the conductive section 41 is greater than that of the pressing section 42, and the pressing section 42 is used for pressing the shielding layer of the cable, and the contact end abuts against the conductive section 41, the conductive member 6 can abut against the shielding ring 4, thereby avoiding the phenomenon that the conductive member 6 cannot abut against the shielding ring 4 after the shielding ring 4 is pressed, and thereby ensuring the electrical conduction effect between the conductive member 6 and the shielding ring 4.
[0091] Preferably, the shielding ring 4 further includes a stop section 43 arranged on the side of the conductive section 41 away from the pressing section 42, the outer diameter of the stop section 43 is greater than the inner diameter of the front end of the front cover 5 and greater than the outer diameter of the conductive section 41, so that the front cover 5 can block the stop section 43 to increase the stability of the shielding ring 4.
