[0033] Example:

[0034] refer to Figures 1-4A car waterproof camera connector includes: a shell 1, a connecting shell 2, an outer conductor 3, an insulator 4 and a center pin 5. The shell 1 is provided with a stepped through hole 11. The connecting shell 2 is installed on the shell 1. The connecting shell 2 is crimped to the shell 1. The bottom of the connecting shell 2 is provided with a first waterproof ring 21. The outer conductor 3 is installed in the connecting shell 2. One end of the outer conductor 3 extends into the shell 1 through the stepped through hole 11. The outer conductor 3 is crimped to the shell 1. A second waterproof groove 31 is provided on the outer conductor 3. The second waterproof groove 31 The upper sleeve is provided with a second waterproof ring 32, which is located between the outer conductor 3 and the connecting shell 2, thereby preventing rainwater from entering the shell 1 from the connection between the connecting shell 2 and the outer conductor 3. The outer conductor 3 and the insulator 4 are installed between the outer conductor 3. A third waterproof groove 41 is opened on the insulator 4. The third waterproof ring 42 is sleeved on the third waterproof groove 41. The third waterproof ring 42 is located between the insulator 4 and the outer conductor 3, thereby preventing rainwater from entering the shell 1 from the connection between the insulator 4 and the outer conductor 3. A center pin 5 is installed in the insulator 4.

[0035] refer to Figure 3 and Figure 4 In order to further prevent rainwater from entering the shell 1 from between the connecting shell 2 and the shell 1, a waterproof portion 22 is extended outward from the bottom of the connecting shell 2. The bottom surface of the waterproof portion 22 is press-fitted to the surface of the shell 1, and the bottom surface of the connecting shell 2 is press-fitted to the surface of the step through-hole 11. The step through-hole 11 also plays a role in supporting the position of the connecting shell 2. A waterproof cavity 6 is formed between the waterproof portion 22, the connecting shell 2, and the surface of the shell 1. The first waterproof ring 21 is arranged in the waterproof cavity 6, thereby further preventing rainwater from entering the shell 1 from between the shell 1 and the connecting shell 2.

[0036] refer to Figure 3 and Figure 4 The inner wall of the connecting shell 2 extends toward the outer conductor 3 with a crimping flange 23, and the outer conductor 3 is crimped to the connecting shell 2 by the cooperation between the outer wall and the flange. On the other hand, the position of the crimping flange 23 can be controlled to control the depth of one end of the outer conductor 3 extending into the shell 1. Through effective control, the part of the outer conductor 3 extending into the shell 1 can be made almost flush with the shell 1, thereby saving space in the shell 1 while improving product performance, making it easier for customers to select PCBs and electronic components, and simplifying the manufacturing process of the product. The use of a second waterproof ring 32 between the connecting shell 2 and the outer conductor 3 can effectively improve the strength to withstand air pressure, and the air pressure can reach 190Kpa. The crimping connection method used between the outer conductor 3 and the connecting shell 2 saves production cycle and improves efficiency compared to the molding method of rubber encapsulation.

[0037] refer to Figure 3 and Figure 4A blocking flange 33 that cooperates with the insulator 4 extends inside the outer conductor 3. One end of the insulator 4 abuts against the blocking flange 33, thereby limiting the position of one end of the insulator 4 inside the outer conductor 3. The other end of the insulator 4 abuts against a fixing ring 7, which is installed on the outer conductor 3. The fixing ring 7 limits the position of the other end of the insulator 4 inside the outer conductor 3, so that the fixing ring 7 can fix the insulator 4 on the outer conductor 3.

[0038] refer to Figure 1 and Figure 2 In order to prevent the outer conductor 3 from rotating relative to the connecting shell 2 during installation, transportation or use, a limiting protrusion extends from the inner wall of the connecting shell 2, and a limiting groove 34 is provided on the outer wall of the outer conductor 3. The limiting groove 34 cooperates with the limiting protrusion to achieve the locking position between the outer conductor 3 and the connecting shell 2, thereby stabilizing the position between the outer conductor 3 and the connecting shell 2.

[0039] refer to Figure 1 and Figure 2 A positioning groove 35 is provided on the outer conductor 3, and a positioning block 25 is extended on the connecting shell 2 to cooperate with the positioning groove 35. The positional relationship between the outer conductor 3 and the connecting shell 2 is determined by the positional relationship between the positioning groove 35 and the positioning block 25, thereby avoiding repeated attempts to install the outer conductor 3 and the connecting shell 2 due to the inaccurate relative angular position between the outer conductor 3 and the connecting shell 1 and the failure of the limiting groove 34 to engage the limiting protrusion, thereby facilitating the assembly between the outer conductor 3 and the connecting shell 1.

[0040] refer to Figures 1-4 The shell 1 is made of aluminum alloy material, which improves the hardness while providing better durability and a more high-end connector, and has good thermal conductivity. It reduces the use of internal heat dissipation auxiliary materials, simplifies assembly, saves the cost of parts, and can achieve very good heat dissipation effect.

[0041] refer to Figure 2 and Figure 4 A limiting block 51 extends from the center needle 5 , and the limiting block 51 cooperates with the insulator 4 . The limiting block 51 is used to stabilize the position between the center needle 5 and the insulator 4 .

[0042] The waterproof connector of the utility model has a reasonable and simple structural design, can effectively be waterproof and save space in the housing 1, simplifies the manufacturing process of the product, improves the product performance to 4GHz, and the air pressure can reach 190Kpa.
