Description

Technical Field

[0001] This utility model relates to the field of electronic components technology, specifically to a connector shielding shell. Background Technology

[0002] With the rapid development of electronic technology, electronic devices have become indispensable daily necessities. These devices inevitably use connectors, and to address the electromagnetic interference (EMI) caused by them, a shielding shell is needed to enclose them and create a barrier against external interference. Current shielding shells often use a U-shaped frame connected to the electronic component housing via solder joints. However, this frame cannot completely enclose the electronic component housing, leaving it susceptible to EMI. Furthermore, these shells have low compatibility, are inconvenient for disassembly and reassembly, and fail to meet the growing demands of users. Therefore, there is a need for a connector shielding shell with a simple structure that is easy to assemble and disassemble. Utility Model Content

The limiting spring piece 11 extends and bends toward the limiting groove 16, and at least partially extends into the limiting groove 16 to contact the limiting piece 3 disposed in the limiting groove 16.

[0026] The second housing 2 is disposed on the upper side of the first housing 1 and together with the first housing 1 form a receiving groove for placing the connector; on one side of the second housing 2, corresponding to the position of the guide groove 15, a guide piece 21 adapted to the guide groove 15 is provided; on the other side of the second housing 2, corresponding to the position of the limiting spring piece 11, a notch 22 is provided. The guide piece 21 is inserted into the guide groove 15, and the limiting spring piece 11 is engaged in the notch 22, so that the second housing 2 and the first housing 1 are connected.

[0027] The connector shielding shell of this solution is suitable for electromagnetic shielding of the connector. First, the connector is installed inside the second housing 2. Then, the second housing 2 is pushed toward the first port 13 of the first housing 1, so that the guide piece 21 on one side of the second housing 2 is inserted into the guide groove 15, and the limiting spring piece 11 on the first housing 1 is engaged in the recess 22 on the other side of the second housing 2. Then, the second housing 2 is pressed down, so that the locking feet 24 on both sides of the housing are engaged with the locking tabs on the connecting pieces 12 on both sides of the first housing 1 near the second port 14. Subsequently, the limiting piece 3 is inserted into the limiting groove 16 to squeeze the free end of the limiting spring piece 11, so that the limiting spring piece 11 is engaged with the recess 22 of the second housing 2. At this time, the second housing 2 and the first housing 1 enclose the connector, so that it is stably held in the receiving groove formed by the second housing 2 and the first housing 1, which is easy to assemble and disassemble.

[0028] In this embodiment, as Figure 3 As shown, one side of the first housing 1 extends upward and folds inward to form a first folded edge 17. The guide groove 15 is disposed on the first folded edge 17, and its opening faces the second port 14.

[0029] Specifically, the front end of the first housing 1 is the second port 14, the rear end is the first port 13, the left side extends upward perpendicular to itself, and the upper end is folded to the right to form a first folded edge 17. The guide groove 15 with an opening facing forward is opened on the first folded edge 17.

[0030] In this embodiment, as Figure 3 As shown, the first folded edge 17 is provided with a protrusion 19, which is located on the side of the guide groove 15 near the second port 14. The width of the protrusion 19 gradually decreases from the second port 14 toward the first port 13.
