An outer protective housing 8 is mounted outside the mounting housing 1, with spiral heat dissipation features around the outer wall of the outer protective housing 8. The fins 9 and the spiral heat dissipation fins 9 are integrated with the outer protective shell 8. The inner wall of one end of the outer protective shell 8 is provided with an installation thread 801, and one end of the installation thread 801 is provided with a limiting groove 802. A sealing gasket 10 is installed inside the limiting groove 802. The components can be easily installed through the installation chamber 101. The connector 2 can be easily installed and fixed to the installation shell 1 through the fixing screw 3. The connector 6 can be easily installed and fixed to the sealing seat 4 through the fixing screw 7. The outer protective shell 8 provides protection for the coaxial attenuator, and the spiral heat dissipation fins 9 improve the heat dissipation performance of the coaxial attenuator, thus facilitating heat dissipation of the coaxial attenuator. It should be noted that, in order to save space and highlight the innovative elements of this patent, the specific working principle and process of the coaxial attenuator will not be described in detail in this patent.

[0025] See Figure 4 and Figure 5The sealing gasket 5 is connected to the sealing groove 401 by adhesive. One end of the mounting housing 1 is located inside the sealing groove 401 and is in contact with the sealing gasket 5. The sealing gasket 5 can improve the sealing effect between the outer protective housing 8 and the sealing seat 4.
