[0026] Embodiment one

[0027] As Figure 4As shown, in this embodiment, multiple fixing plates 41 are fixedly connected between multiple reinforcing ribs 4 located on the same side, multiple fixing plates 41 located at shielding shell 1 2 are fixedly connected to shielding shell 1 2, and multiple fixing plates 41 located at shielding shell 2 3 are fixedly connected to shielding shell 2 3.

[0029] Example 2

[0030] like Figure 2 and Figure 3 As shown, in this embodiment, the end of the shield shell 2 away from the connector 1 is fixedly connected to the connecting block 23, which is fixedly connected to the locking block 21, and the end of the shield shell 3 away from the connector 1 is fixedly connected to the connecting block 32, which is fixedly connected to the stop block 31.
