[0017] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the following will describe the specific embodiments of the present utility model in detail with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0018] By providing a fully shielded BNC connector in an embodiment of the present application, the problem that the BNC connector in the prior art has signal leakage and cannot ensure the fully shielded effect is solved.

[0019] As Figures 1 to 5 shown, an embodiment of the present application: a fully shielded BNC connector 100, comprising: an outer conductor 10, a female pin 20, a fully shielded body 40, a bent pin 50, a front rubber core 30 and a rear rubber core 60. After the female pin 20 passes through the front rubber core 30, the two are arranged inside the outer conductor 10. After the bent pin 50 passes through the rear rubber core 60, the two are arranged inside the fully shielded body 40. The female pin 20 and the bent pin 50 are connected. A riveting post 101 is provided on the outer conductor 10, and a through hole 401 is provided at a corresponding position on the fully shielded body 40. When the outer conductor 10 and the fully shielded body 40 are connected, after the riveting post 101 passes through the through hole 401, the conductor 10 and the fully shielded body 40 are riveted and connected.

[0020] More specifically, one end of the outer conductor 10 extends outwardly to be provided with a first flange 11, and the riveting post 101 is arranged on the first flange 11. The number of the pressing posts 101 can be set to any number, such as 2, 3 or 4. Correspondingly, one end of the fully shielded body 40 close to the outer conductor 10 extends outwardly to be provided with a second flange 43, and the through hole 401 is arranged on the second flange 43. Similarly, the number of the through holes 401 can also be set to any number, such as 2, 3 or 4.

[0021] By providing the riveting post 101 on the outer conductor 10 and the through hole 401 at a corresponding position on the fully shielded body 40, after the riveting post 101 passes through the through hole 401, the material is deformed and expanded by riveting to fill the through hole 401, and a reverse buckling structure is formed for fixing (as Figure 5 shown).

[0022] As Figures 2 - 4As shown, one end face of the fully shielded body 40 away from the outer conductor 10 is a closed surface 41, which can ensure that the signal does not leak out and achieve the effect of full shielding; a bottom through hole 403 is provided on the lower end face of the fully shielded body 40. The bent pin 50 placed inside the fully shielded body 40 has a right-angled structure, including a horizontal end 501 and a vertical end 502. The female pin 20 has a connecting portion 202 in the middle and a fitting groove 201 at the end. The horizontal end 501 of the bent pin 50 is inserted into the fitting groove 201, and the vertical end 502 extends out of the bottom through hole 403 for connection with other connectors.

[0023] Further referring to Figure 2 , a first through hole 301 is provided in the center of the front rubber core 30. The female pin 20 passes through the first through hole 301 and is fixed inside the outer conductor 10. The front rubber core 30 can just seal the inside of the outer conductor 10. A second through hole 601 is provided in the center of the rear rubber core 60. The vertical end 502 of the bent pin 50 passes through the second through hole 601 and is fixed inside the fully shielded body 40. The rear rubber core 60 can just seal the bottom through hole 403. Through the setting of the two rubber cores, it can be ensured that the female pin 20 and the bent pin 50 are firmly fixed inside the outer conductor 10 and the fully shielded 40 body, further preventing signal leakage.

[0024] Referring to Figure 3 , a plurality of guiding grooves 102 are further provided on the inner surface of one end of the outer conductor 10 close to the riveting post 101. A plurality of guiding rib columns 402 are provided around the port 42 where the fully shielded body 40 is connected to the outer conductor 10. The guiding rib columns 402 are directionally engaged with the guiding grooves 102. Such a setting can ensure the accurate and directional connection of the outer conductor 10 and the fully shielded body 40. The guiding rib columns 402 and the guiding grooves 102 can play a role in preventing misassembly and misalignment.

[0025] The installation method of the fully shielded BNC connector of the present utility model is as follows:

[0026] 1. Install the bent pin 50 into the rear rubber core 60, then install it into the fully shielded body 40, and make three dots at the bottom (such as Figure 3 );

[0027] 2. The female pin 20 is provided with a fitting groove 201 structure. Install the female pin 20 into the front rubber core 30. The connecting portion 202 is fixedly engaged in the front rubber core 30. The female pin 20 is docked and connected with the bent pin 50 and is pre-installed and fixed in the fully shielded body 40 together with the front rubber core 30;

[0028] 3. Insert the outer conductor 10 into the fully shielded body 40 in an insertion connection. The three guiding rib columns 402 of the fully shielded body 40 are engaged with the three guiding grooves 102 of the outer conductor 10, and guide the three riveting posts 101 of the outer conductor 10 to pass through the through holes 401 of the fully shielded body 40. After being inserted, the protruding parts of the riveting posts 101 are riveted by a riveting process to cause the material to deform and expand to fill the outer conductor hole grooves, and a reverse buckle structure is formed for fixation.

[0029] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as falling within the scope described in this specification.
