Two buckling parts 112 are respectively formed on the housing 11 of the receptacle connector 1 corresponding to the two side surfaces of the elastic buckling parts 29, and the elastic buckling parts 29 of the shielding case 2 are used for buckling with the buckling parts 112 of the receptacle connector 1 already disposed on the substrate 200. In detail, the elastic buckle 29 has an elastic arm 291 and a buckle 292 formed at an end of the elastic arm 291. The shielding case 2 further has two openings 232 formed on the two side plates 23, the elastic arm 291 of the elastic fastener 29 is folded back on the outer side of the corresponding side plate 23 from the lower edge of the corresponding side plate 23, and the fastening piece 292 extends into the shielding case 2 through the corresponding opening 232. It should be noted that, the buckling portions 112 are bumps in the second embodiment, so that when the shielding can 2 is covered and fixed on the receptacle connector 1 fixed on the substrate 200 from top to bottom, the buckling pieces 292 of the elastic buckling pieces 29 can elastically cross over the buckling portions 112 from top to bottom and buckle against the lower edges of the buckling portions 112, but the buckling portions 112 may also be in the form of grooves for accommodating the buckling pieces 292 in other embodiments. The elastic fasteners 29 for fastening with the fastening portions 112 of the receptacle connector 1 already disposed on the substrate 200 enable the receptacle connector 1 previously assembled on the substrate 200 to be positioned and assembled with the shielding case 2, so as to fix the shielding case 2 during the process of turning over the substrate 200 and locking the fastening member 300, thereby preventing the shielding case 2 from falling off during the locking process.

To sum up, the connector assembly 100 of the present invention is configured by the positioning column 27 integrally formed with the shielding case 2, and assembled with the fastening cap 3 and the fixing piece 28 integrally extending out of the shielding case 2, so that the shielding case 2 can be easily positioned and assembled in the process of assembling the substrate 200, and the components manufactured by die casting can be reduced to save the cost. In addition, the elastic fasteners 29 for fastening with the fastening portions 112 of the receptacle connector 1 already disposed on the substrate 200 enable the receptacle connector 1 assembled in advance to be positioned and then assembled with the shielding case 2, so as to fix the shielding case 2 during the process of turning over the substrate 200 and locking the fastening member 300, thereby preventing the shielding case 2 from falling off during the locking process.
