As shown in Fig. 8, in conjunction with Figs. 1-7, the method for mounting an assembly of a plug-in connector component comprises: step S101 , mounting a grounding element 15 in a grounding element mounting section 130 of an insulator 11 of the assembly, wherein a grounding element body 151 of the grounding element 15 is provided at the inner side of a side wall 131 of the grounding element mounting section 130, and a housing contact portion 153 of the grounding element 15 is provided on the outer side of the side wall 131 through an opening 133 provided on the side wall 131 ; specifically, the grounding element body 151 is in contact with a ground wire on the inner side of the side wall 131 ; step S103: fixing a contact 173 on the inner side of a mounting plate 177 through a contact fixing portion 175; and step S105, mounting a contact piece mounting portion 171 on a contact piece mounting section 190 through the mounting plate 177, so that the contact 173 extends into a through hole 111 of a plug-in section of the insulator 11. In this way, a grounding element is provided in the assembly of the plug-in connector component, so as to provide grounding for the housing of the assembly of the plug-in connector component, thereby improving the safety of the assembly of the plug-in connector component; moreover, various components in the assembly of the plug-in connector component are easily mounted together without using a screw mounting manner, and the mounting is simple and convenient.

As shown in Fig. 8, according to exemplary embodiments of the present application, the method for mounting an assembly of a plug-in connector component further comprises: step S107, mounting the insulator 11 to a housing 16 by a housing mounting section 180 of the insulator 11 , and the housing contact portion 153 of the grounding element 15 being in ground contact with the housing 16.

Embodiments of the present application provide a technical solution of an assembly of a plug-in connector component, and a plug-in connector component and system, so as to at least solve the technical problem of inconvenience in an assembling manner of multiple components of a plug-in connector, and achieve the technical effects of easily and safely grounding the plug-in connector and easily assembling the plug-in connector.

In the described embodiments of the present application, the description of each embodiment has its own emphasis. For the part not detailed in a certain embodiment, please refer to the relevant description in other embodiments.

In the several embodiments provided in the present application, it should be understood that the disclosed technical content may be implemented in other manners. The apparatus embodiments described above are merely illustrative. For example, the division of a unit or a module is only a logical function division, and in actual implementation, there may be another division manner, for example, multiple units or modules or assemblies may be combined, or can be integrated into another system, or some features can be ignored or not executed. In addition, the coupling or direct coupling or communication connection shown or discussed may be an indirect coupling or communication connection through some interfaces, modules or units, and may be electrical or other forms.

The units or modules described as separate components may or may not be physically separated, and the components displayed as units or modules may or may not be physical units or modules, that is, may be located in one place, or may be distributed in a plurality of network units or modules. Some or all of the units or modules may be selected according to actual needs to achieve the purpose of the solutions of the embodiments.

The units or modules described as separate components may or may not be physically separated, and the components displayed as units or modules may or may not be physical units or modules, that is, may be located in one place, or may be distributed in a plurality of network units or modules.
