Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0025] See also Figure 1-5 This utility model provides a connector mounting protection structure, including a housing 1 and a printed circuit board 5 disposed inside the housing 1. The housing 1 has an inwardly extending mounting cavity 2 facing the printed circuit board 5. An insulator 3 is embedded in the mounting cavity 2. A contact 4 that is soldered and connected to the printed circuit board 5 is disposed inside the insulator 3. The contact 4 is fixed inside the insulator 3. A limiting part 6 is provided on the mounting cavity 2. The limiting part 6 is used to abut against the insulator 3 to restrict the movement of the insulator 3 along the mounting cavity 2 towards the printed circuit board 5.

[0026] Among them, such as Figure 1-3 As shown, the upper end of the housing 1 is recessed downwards to form a mounting cavity 2. The mounting cavity 2 is integrally formed with the housing 1. The mounting cavity 2 is a through cavity, cylindrical in shape with openings at both ends. The extension length, radial dimension, and specific shape of the mounting cavity 2 are set according to needs. The limiting part 6 is located at the end of the mounting cavity 2 facing the printed circuit board 5. The insulator 3 has a protrusion 33 at the end facing the printed circuit board 5. The limiting part 6 has a mounting notch 61 for the protrusion 33 to pass through. The limiting part 6 is annular. The insulator 3 is installed inside the mounting cavity 2, which provides protection for the insulator 3. The limiting part 6 does not contact the printed circuit board 5 and is integrally formed with the mounting cavity 2.

[0027] Combine Figure 1 、 Figure 2 and Figure 5As shown, the insulator 3 is provided with a sealing groove 31, and a sealing ring 7 is provided in the sealing groove 31 to abut against the inner wall of the mounting cavity 2. By setting the sealing ring 7, the seal between the insulator 3 and the mounting cavity 2 is achieved. The inner wall of the mounting cavity 2 is provided with a guide protrusion 21 along its length direction. The length of the guide protrusion 21 is less than the length of the mounting cavity 2. The lower end of the guide protrusion 21 abuts against the upper end of the limiting part 6. The insulator 3 is provided with a guide groove 32 that cooperates with the guide protrusion 21. By setting the guide protrusion 21 and the guide groove 32, it is convenient for the insulator 3 to be installed in the mounting cavity 2.

[0028] Specifically, the inner wall of the mounting cavity 2 is provided with multiple reinforcing ribs 22 that are interference-fitted with the insulator 3. The length of the reinforcing ribs 22 is less than the length of the guide protrusion 21. The lower end of the reinforcing ribs 22 abuts against the upper end of the limiting part 6. The multiple reinforcing ribs 22 are evenly distributed circumferentially along the inner wall of the mounting cavity 2. The cross-section of the reinforcing ribs 22 is semi-circular. The interference fit between the reinforcing ribs 22 and the insulator 3 is used to fix the insulator 3. The protrusion 33 is provided with a glue-filling groove 331. The glue-filling groove 331 contains a fixing body formed by glue filling.

[0029] Combine Figure 3 As shown, two fixing seats 12 are provided opposite to each other inside the housing 1. The lower end of the fixing seat 12 is provided with a positioning post 13. The printed circuit board 5 is provided with a slot that is interference fit with the positioning post 13. The installation and fixing of the printed circuit board 5 is achieved by the interference fit between the positioning post 13 and the slot. The installation is convenient. Compared with the existing method of using screws to press the printed circuit board, it effectively avoids the printed circuit board 5 from being stressed. It should be noted that the parts not described in detail in this application are all prior art.

[0030] In addition, the box body 1 has an opening on the side opposite to the mounting cavity 2, and a sealing plate 1 is provided at the opening. The box body 1 and the sealing plate 1 are fixed together by bolts.

[0031] When mating with the adapter connector, the contact 4 will be subjected to axial force. Since the contact 2 is fixed to the insulator 3, the force on the contact 4 will be transmitted to the insulator 3. By setting the limiting part 6, the force on the insulator 3 will be transmitted to the limiting part 6, thereby effectively avoiding the printed circuit board 5 from being subjected to force and improving the reliability of the product.
