In the utility model, the technical scheme of connector is:
A kind of connector, comprise the connector shell that insulator that contact is installed and front end are inserted terminal, be provided with the installing hole of packing into from front to back for described insulator in connector shell, rear side in described insulator on the hole wall of described installing hole is provided with spacing direction shielding ring installation step forward, shielding ring with described connector shell conducting is installed on described shielding ring installation step, be provided with on insulator with described shielding ring installation step and be oppositely arranged, limit the shielding ring stopping surface of shielding ring fore-and-aft direction moving range to coordinate with installation step.
Be provided with the ripple spring of realizing shielding ring and connector shell conducting between described shielding ring and connector shell.
The rear end of described shielding ring is provided with spring fitting step annular, that be oppositely arranged with described shielding ring installation step, and described ripple spring top is loaded between described shielding ring installation step and spring fitting step.
Described shielding ring stopping surface consists of the rear end face of described insulator.
The beneficial effects of the utility model are: due to the spacing direction of shielding ring installation step forward, so in use in the first installing hole of packing into from front to back of shielding ring, and be limited in shielding ring installation step place, then, by insulator in the installing hole of packing into from front to back, shielding ring stopping surface on insulator with the shielding ring installation step, coordinate and shielding ring is fixed spacing, the assembling high conformity of shielding ring and insulator; Simultaneously, use the connector of this shielding ring mounting structure when assembling with cable, first by the cable wire stripping, cable after wire stripping by rear to front in turn through connector shell and shielding ring, then by the screen of cable and shielding ring welding, the wire of cable and the welding of the contact on insulator, after having welded, will in shielding ring and the insulator installing hole of packing in turn from front to back, get final product, do not need the screen of cable and wire are separated to respectively rear side and the front side of connector shell, very simple, convenient of the connection procedure of cable.
