Abstract

A shielding shell used to at least partially surround signal terminals includes a first side wall, a second side wall and a third side wall. The second side wall connects the first side wall and the third side wall. The first side wall and the third side wall are disposed face to face. An end of at least one of the first side wall, the second side wall and the third side wall includes a deflection portion bent inwardly. The deflection portion is used to guide insertion of the shielding shell into a mating connector. As a result, a better shielding effect on the signal terminals can be provided. Besides, it is easy to guide insertion of the shielding shell into the mating connector.

wherein the shielding shell further comprises a fourth side wall, the fourth side wall and the second side wall are disposed face to face;
wherein the first side wall, the second side wall, the third side wall and the fourth side wall jointly form a hollow portion.

2. The shielding shell according to claim 1 , wherein each end of the first side wall, the second side wall, the third side wall and the fourth side wall comprises the deflection portion; and wherein the deflection portions are separated from each other.

3. A shielding shell for at least partially surrounding signal terminals, the shielding shell comprising:
a first side wall;
a second side wall; and
a third side wall, the second side wall connecting the first side wall and the third side wall, and the first side wall and the third side wall are disposed face to face;
wherein an end of at least one of the first side wall, the second side wall and the third side wall comprises a deflection portion which is bent inwardly, and the deflection portion is adapted to guide insertion of the shielding shell into a mating connector;
wherein the shielding shell further comprises a first extension piece protruding beyond the first side wall, a pair of first slots located on both sides of the first extension piece, a second extension piece protruding beyond the third side wall, and a pair of second slots located on both sides of the second extension piece;
wherein the first extension piece and the second extension piece are adapted for contacting ground terminals; and
wherein the first slots and the second slots are adapted to fix metal shields, and make the shielding shell be in contact with the metal shields.

4. The shielding shell according to claim 2 , further comprising a mounting portion extending from the hollow portion, the mounting portion comprising a base portion, a first bending portion bent from one side of the base portion, and a second bending portion bent from the other side of the base portion;
wherein the base portion is connected to the third side wall, the first bending portion and the second side wall are located on a same side, and the second bending portion and the fourth side wall are located on a same side.

5. The shielding shell according to claim 4 , wherein the base portion is coplanar with the third side wall, the first bending portion protrudes outwardly beyond the second side wall, and the second bending portion protrudes outwardly beyond the fourth side wall.

6. The shielding shell according to claim 5 , wherein the first bending portion comprises a plurality of first barbs on a side away from the third side wall, the second bending portion comprises a plurality of second barbs on a side away from the third side wall, and the first barbs and the second barbs are adapted for being fixed in a housing.

7. The shielding shell according to claim 2 , wherein the mounting portion comprises a retaining portion bent from a bottom of the base portion in a direction toward the first side wall.

8. The shielding shell according to claim 4 , further comprising a first tail portion extending from the first bending portion and a second tail portion extending from the second bending portion; wherein the first tail portion and the second tail portion are adapted for being mounted on a circuit board.

9.
