The number of the limiting grooves 131 can be 5, and the 5 limiting grooves 131 are arranged at intervals along the circumference of the limiting portion 13, and each limiting groove 131 is formed by a concave surface of one side of the limiting portion 13 adjacent to the fixing member 5. The 5 first limiting protrusions 41 correspond to the 5 limiting grooves 131 one by one. When the first seal 4 is installed on the housing assembly 1, the 5 limiting grooves 131 cooperate with the corresponding first limiting protrusions 41 to fix the first seal 4 on the limiting portion 13 of the housing assembly 1, thereby enhancing the connection reliability between the first seal 4 and the limiting portion 13, so as to limit the displacement and rotation of the first seal 4, thereby enhancing the sealing effect of the first seal 4.

[0054] According to some embodiments of the present invention, the housing assembly 1 includes a first housing 11 and a second housing 12, the first housing 11 is sleeved on the outer periphery of the second housing 12 and connected to the outer peripheral wall of the second housing 12, and the first shielding inner shell 3 is located between the outer peripheral wall of the second housing 12 and the inner peripheral wall of the first housing 11. Figure 1-Figure 9 The second shell 12 can be connected to the first shell 11 through a connecting column, so that the shell assembly 1 is an integrally formed part. A sliding hole is set at the relative position of the first shielding inner shell 3 and the connecting column. During installation, the sliding hole is opposite to the connecting column to slide the first shielding inner shell 3 between the first shell 11 and the second shell. At this time, the first shielding inner shell 3 is sleeved on the outer periphery of the second shell 12. The first shell 11 and the second shell 12 can increase the protection of the first shielding inner shell 3 to prevent the first shielding inner shell 3 from being damaged.

[0055] Among them, the outer peripheral wall of the second shell 12 is provided with at least one second limiting protrusion 122, the outer peripheral wall of the first shielding inner shell 3 is connected with at least one second elastic piece 32, the second elastic piece 32 extends along the axial direction of the first shielding inner shell 3, and the free end of the second elastic piece 32 stops against the second limiting protrusion 122.

[0056] like Figure 4As shown, the second limiting protrusion 122 is formed by the outer peripheral wall protrusion of the second shell 12. The cross-sectional area of ​​the second limiting protrusion 122 can be rectangular, trapezoidal, cylindrical, etc. One end of the second elastic piece 32 is connected to the outer peripheral wall of the first shielding inner shell 3, and the other end of the second elastic piece 32 extends obliquely in a direction away from the first shielding inner shell 3. When the first shielding inner shell 3 is matched with the second shell 12, the free end of the second elastic piece 32 stops against the second limiting protrusion 122, so that the first shielding inner shell 3 cannot move further. At this time, it indicates that the first shielding inner shell 3 has been installed in place, ensuring that the relative displacement between the first shielding inner shell 3 and the second shell 12 is fixed, enhancing the connection stability between the first shielding inner shell 3 and the second shell 12, and ensuring the structural stability of the plug-in assembly 100.

[0058] For example, in Figure 1 In the example, the step portion 111 is formed by the inner wall of the first shell 11 protruding in the direction away from the first shell 11. When the first shielding inner shell 3 is sleeved on the second shell 12, one end of the first shielding inner shell 3 abuts against the step portion 111 of the first shell 11, so that the moving space of the first shielding inner shell 3 is limited and the first shielding inner shell 3 cannot be displaced.
