[0026] The latching member 3 is fixed in the retaining grooves 141 on both sides of the insulating body 1 . The latching member 3 is provided with a latching portion 31 . The latching portion 31 passes through the retaining grooves 141 and protrudes into the receiving cavity 10 for latching with a docking connector (not shown).

[0027] The metal lower shell 4 includes a bottom wall 41, a plurality of lower spring plates 42 extending forward and parallel from the front end of the bottom wall 41, and left and right wings 43 extending upward from the left and right sides of the rear end of the bottom wall 41. The bottom wall 41 is stepped and covers the bottom surface of the main body 11 and the bottom surface of the bottom wall 13 of the insulating body 1. The lower spring plates 42 are terminated with lower elastic portions 421, which extend forward beyond the front edge of the bottom wall 13 and project into the receiving cavity 10.

The two side portions 52 cover the two side walls 14 of the insulating body 1 and the outer side surface 111 of the main body 11. The shielding bottom shell 5 can play a role in preventing electromagnetic interference.

[0029] The metal upper shell 6 includes a top wall 61, a plurality of upper spring tabs 62 extending forward and side by side from the front end of the top wall 61, a rear wall 63 extending downward from the rear end of the top wall 61, and two side walls 64 extending downward from the left and right sides of the top wall 61. The top wall 61 covers the top surface of the main body 11, the rear wall 63 covers the rear end surface (not shown) of the main body 11, and the two side walls 64 cover the outside of the side portions 52 of the shielding bottom shell 5. The plurality of upper spring tabs 62 form the top wall of the receiving cavity 10. The upper spring tabs 62 are provided with connecting arms 621 and upper elastic portions 622 at the ends of the connecting arms 621.

The top cover 7 includes a top plate 71, side plates 72 extending downward from the top plate 71, and a rear extension plate 73 extending rearward from the top plate 71. The top plate 71 covers the upper spring plate 62 of the metal upper shell 6. The side plates 72 cover the outside of the side portion 52 of the shielding bottom shell 5. The side plates 72 are roughly coplanar with the side walls 64 of the metal upper shell 6. The rear extension plate 73 covers the top wall 61 of the metal upper shell 6. The top plate 71, side plates 72, and rear extension plate 73 are each integrally formed, providing excellent electromagnetic interference protection. The top plate 71 is raised as a whole relative to the rear extension plate 73, while the connecting arm 621 of the upper spring plate 62 is coplanar with the top wall 61. This creates a certain gap between the top plate 71 and the connecting arm 621, which allows the connecting arm 621 to have a certain amount of space for external elastic deformation. The upper spring portion 622 extends beyond the front edge of the top plate 71 to prevent it from interfering with the top plate 71 when it is released. The top cover 7 covers the upper spring plate 62 on the top side of the metal upper shell 6, protecting the upper spring plate 62 from excessive outward deflection and causing damage. It also enhances the electromagnetic interference protection function of the receptacle connector 100.

[0031] When assembling the socket connector 100 of the present invention, the terminal module 2 is first assembled into the insulating body 1, and then the retaining members 3 are fixed to both sides of the insulating body 1. Then, the metal lower shell 4 and the shielding bottom shell 5 are assembled in sequence, and finally the metal upper shell 6 and the top cover 7 are assembled.

[0032] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
