Referring to FIGS. 1 and 2, anti-electromagnetic-interference elastic sheets 3 disposed on the walls of the shell 1 are second anti-electromagnetic-interference elastic sheets 3b. A second positioning sheet 32b extends from a respective one of the two metal sheets 31 of each of the second anti-electromagnetic-interference elastic sheets 3b. The second limit holes 14 are disposed on the walls of the shell 1. Each of the second positioning sheets 32b is guided through a respective one of the second limit holes 14 and abuts against a respective one of the walls of the shell 1 so that the anti-electromagnetic-interference elastic sheets 3b are prevented from falling off and the reliability of the connection through the second anti-electromagnetic-interference elastic sheets 3b is improved.
In the embodiment, after the first anti-electromagnetic-interference elastic sheets 3a are mounted on the divider plates 2, the first positioning sheet 32a may be riveted to abut against the walls of the shell 1. After the second anti-electromagnetic-interference elastic sheets 3b are mounted on the shell 1, the second positioning sheets 32b may be riveted to abut against the walls of the shell 1. The first positioning sheets 32a and the second positioning sheets 32b enable the anti-electromagnetic-interference elastic sheets 3 to be secured to the divider plates 2 or the shell 1.
Referring to FIG. 2, the first positioning sheets 32a at the same end of each of the first anti-electromagnetic-interference elastic sheets 3a are staggered. The first anti-electromagnetic-interference elastic sheet 3a is secured at different positions to improve the reliability of the connection through the first anti-electromagnetic-interference elastic sheet 3a.
To improve the reliability of the connection through the first anti-electromagnetic-interference elastic sheets 3a, referring to FIGS. 3 and 7, each one of the two metal sheets 31 of each first anti-electromagnetic-interference elastic sheet 3a is provided with first protrusions 311a spaced apart. Each of the divider plates 2 is provided with a first positioning hole 23. Each of the first protrusions 311a stucks at a respective one of the first positioning holes 23. Optionally, each of the two metal sheets 31 of each of the first anti-electromagnetic-interference elastic sheets 3a is provided with a first protrusion 311a. The first protrusions 311a are arranged at opposite positions of the two metal sheets 31, and the two first protrusions 311a opposite to each other stuck at the same first positioning hole 23. Alternatively, the first protrusions 311a of the two metal sheets 31 of each of the first anti-electromagnetic-interference elastic sheets 3a are provided at staggered positions of the two metal sheets 31.

Optionally, the width of the ledge 33b ranges from one-third to one-second of the width of the second positioning sheet 32b. For example, the width of the ledge 33b may be one-third, or seven-eighteenths, or four-ninths, or one-second of the width of the second positioning sheets 32b so that the ledge 33b with the width is capable of withstanding a larger bending moment. When the second anti-electromagnetic-interference elastic sheets 3b are mounted on the shell 1, the second anti-electromagnetic-interference elastic sheets 3b are moved to abut against adjacent two sides of the second limit hole 14. When the second positioning sheet 32b abuts against the side of the second limit hole 14 in the direction toward the side where the ledge 33b is disposed, the second positioning sheet 32b is riveted. The ledges 33b are disposed to prevent the second positioning sheets 32b to come out of the second limit holes 14 so that the reliability of the connection of the second anti-electromagnetic-interference elastic sheets 3b is improved.
To improve the reliability of the connection of the second anti-electromagnetic-interference elastic sheet 3b, referring to FIGS. 6 to 9, each one of the two metal sheets 31 of each second anti-electromagnetic-interference elastic sheet 3b is provided with second protrusions 311b spaced apart and protruding toward the other one of the two metal sheets 31 of the same one of the second anti-electromagnetic-interference elastic sheets 3b.

Alternatively, the second protrusion 311b is disposed on only one of the metal sheets 31 of each of the second anti-electromagnetic-interference elastic sheets 3b.
For ease of mounting the second anti-electromagnetic-interference elastic sheet 3b, the second positioning sheet 32b extends from the metal sheet 31 of the second anti-electromagnetic-interference elastic sheet 3b in the shell 1. The second positioning sheet 32b is guided through the second limit hole 14 from the inside of the shell 1 to the outside of the shell 1. The second positioning sheet 32b can be riveted from the outer side of the shell 1 to abut against the outer wall of the shell 1 so that it is convenient to mount the second anti-electromagnetic-interference elastic sheet 3b.

The cross-sectional area of the bottom of the snap slot 111 is greater than the cross-sectional area of the end farther from the bottom of the snap slot 111. The block 121 cooperates with the snap slot 111 so that the upper shell 11 and the lower shell 12 are connected to each other more securely.
To improve the stability of the connection between the upper shell 11 and the lower shell 12, referring to FIG. 9, the one ends of the two side walls of the upper shell 11 farther from the block 121 snap between the two side walls of the lower shell 12. The outer sides of the two side walls of the upper shell 11 are provided with snaps 112. Engagement holes 122 are disposed at positions of the lower shell 12 corresponding to the snaps 112. Each of the snaps 112 stucks at a respective one of the engagement holes 122.
In the embodiment, the first anti-electromagnetic-interference elastic sheets 3a are mounted on the divider plates 2, and then the first positioning sheets 32a are riveted to abut against the walls of the shell 1. After the second anti-electromagnetic-interference elastic sheets 3b are mounted on the shell 1, the second anti-electromagnetic-interference elastic sheets 3b are moved so that the ledges 33b are staggered in the second limit holes 14, and then the second positioning sheets 32b are riveted to abut against the walls of the shell 1. The first positioning sheets 32a and the second positioning sheets 32b are disposed to enable the anti-electromagnetic-interference elastic sheets 3 to be stably secured to the divider plates 2 or the shell 1 so that the shielding effect of the shield is ensured and the capability of the connector to resist signal interference is improved.
