[0021] See also Figure 1-Figure 5 As shown, the utility model provides the following technical solutions: a wire-to-board RF connector, comprising: a shell 1, an interface slot 2 is provided on the shell 1, a connector 3 is provided in the interface slot 2, a contact spring 4 is provided in the interface slot 2, a first spring 5 is installed between the contact spring 4 and the shell 1, clamping plates 6 are provided on both sides of the connector 3, a first through slot 7 and a second through slot 8 are provided on the shell 1, and the first through slot 7 and the second through slot 8 are connected, a first piston plate 9 is provided in the first through slot 7, a second piston plate 10 is provided in the second through slot 8, and a first mounting plate 11 is connected between the first piston plate 9 and the clamping plate 6.
[0022] Furthermore, a second mounting plate 12 is connected to the second piston plate 10 , a connecting block 13 is fixed to one end of the second mounting plate 12 extending to the outside of the second through slot 8 , and a clamping assembly is provided between the second mounting plate 12 and the housing 1 .
[0023] Furthermore, the card assembly includes a card slot 14 , a card block 15 and a second spring 16 . The card slot 14 is opened on the inner wall of the second through slot 8 . The card block 15 is installed on one side of the second mounting plate 12 . The second spring 16 is installed between the card block 15 and the second mounting plate 12 .
[0024] Through the above technical solution:
[0025] When in use, the connector 3 is inserted into the interface slot 2, the contact spring 4 touches the connector 3 to transmit the signal, and then the connecting block 13 is pressed to make the card block 15 enter the card slot 14, and the connecting block 13 drives the second piston plate 10 to move in the second through slot 8 through the second mounting plate 12, and the second piston plate 10 squeezes the gas in the second through slot 8, and the first through slot 7 is connected to the second through slot 8, so that the first piston plate 9 in the first through slot 7 moves, and the first piston plate 9 drives the clamping plate 6 to approach the connector 3 through the first mounting plate 11, and the connector 3 is clamped by multiple clamping plates 6, so that the connector 3 is not easy to fall off, which can ensure the stability of the connection and reduce the risk of connection interruption due to vibration, movement or accidental collision, so as to adapt to different environments and usage conditions and ensure that the connection can be kept stable under various circumstances.
[0026] See also Figure 1 and Figure 3 As shown, a protective plate 17 is provided above the shell 1, a rubber pad 18 is installed on the outer wall of the protective plate 17, a hollow column 19 is installed at the top of the shell 1, a movable column 20 is installed on the lower end surface of the protective plate 17, and a part of the movable column 20 is located in the hollow column 19, a third spring 21 is installed between the hollow column 19 and the movable column 20, and a limit assembly is provided between the hollow column 19 and the movable column 20.
[0027] Furthermore, the limiting assembly includes a limiting groove 22 and a limiting block 23. The limiting groove 22 is formed on the inner wall of the hollow column 19, and the limiting block 23 is installed on the outer wall of the movable column 20. The limiting groove 22 and the limiting block 23 are matched.
[0028] Through the above technical solution:
[0029] When in use, the protection plate 17 protects the shell 1. When an object falls from above the shell 1, the impact force first acts on the rubber pad 18, and then the impact force presses the protection plate 17 to move to one side of the shell 1, so that the movable column 20 moves in the hollow column 19, and the third spring 21 is deformed. The rubber pad 18 and the third spring 21 are highly elastic materials. When impacted, they can undergo elastic deformation to absorb and disperse impact energy, and this deformation is reversible, which means that after the impact force is removed, the rubber pad 18 and the third spring 21 can return to their original shape, thereby reducing the impact force and protecting the shell 1. When the movable column 20 moves, it drives the limit block 23 to move in the limit groove 22, thereby limiting the movement of the movable column 20, so that the movable column 20 is not easy to fall off in the hollow column 19.
[0030] For further information, see Figure 1-Figure 2 As shown, an inner conductor 24 is connected to the contact spring 4 , an insulator 25 is wrapped outside the inner conductor 24 , and an outer conductor 26 is arranged outside the insulator 25 .
[0031] Specifically, the inner conductor 24 is the central conductor for transmitting signals in the connector. It is usually a metal wire or lead, which is responsible for transmitting signals from one connector port to another connector port. The outer conductor 26 is the external package around the inner conductor 24, usually composed of a metal sleeve or shielding material. Its main function is to provide signal shielding, reduce the impact of external electromagnetic interference on the signal, and improve the anti-interference ability of the connector. The insulator 25 is located between the inner conductor 24 and the outer conductor 26, and is used to isolate the inner conductor 24 and the outer conductor 26 to prevent direct contact or short circuit between them.
[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
