DETAILED DESCRIPTION

[0028] The present invention will be described in further detail below with reference to the embodiments and accompanying drawings. However, this should not be construed as limiting the scope of the present invention to the following embodiments, as all technologies implemented based on the present invention fall within the scope of the present invention.

[0029] Example

[0030] See also Figure 1-7 , a radio frequency high-reliability fast plug-in expanded beam optical fiber socket, comprising:

[0031] Socket housing 1;

[0032] The pin mounting plate assembly 2 is fixed by the groove and the fixing ring 4 in the socket housing 1 and is potted with glue. In addition, a sealing ring 6 is installed between the socket housing 1 and the pin mounting plate assembly 2 to be suitable for underwater environments such as the ocean;

[0033] The non-contact beam-expanding optical fiber contact 3 is mounted in the pin mounting plate assembly 2 and is used to transmit optical signals modulated by radio frequency signals. Optical signal transmission offers advantages such as high transmission bandwidth, high transmission capacity, high return loss, compact size, light weight, low loss, good anti-interference performance, strong confidentiality, and low crosstalk and interference. The present invention utilizes a socket with a non-contact beam-expanding optical fiber contact 3 for transmitting optical signals modulated by radio frequency signals, achieving the socket's specific high return loss advantage. This reduces signal reflections during signal transmission, thereby reducing signal loss and improving the quality and stability of radio frequency signal transmission.

[0034] In certain embodiments, see Figure 7In the present invention, the non-contact beam-expanding optical fiber contact 3 serves as a beam-expanding optical fiber terminal. Specifically, the non-contact beam-expanding optical fiber contact 3 comprises a crimping ring 35, a ferrule assembly, and a sleeve assembly. The ferrule assembly is secured to the ferrule mounting plate assembly 2 via a clamping claw 26. One end of the ferrule assembly and the crimping ring 35 together secure the optical fiber conductor, ensuring that the non-contact beam-expanding optical fiber contact 3 and the optical fiber conductor do not separate when connected. The other end of the ferrule assembly is connected to the sleeve assembly. Specifically, the ferrule assembly comprises an inner housing 31 and a ceramic ferrule 32, while the sleeve assembly comprises a ceramic sleeve 33 and a self-focusing lens 34. One end of the ceramic ferrule 32 is secured to the inner housing 31, while the other end of the ceramic ferrule 32 is secured to the ceramic sleeve 33 by an interference fit. The self-focusing lens 34 is mounted within the ceramic sleeve 33 and located at the end of the ceramic ferrule 32. When the sleeve assembly is fitted over the ceramic ferrule 32, the ceramic sleeve 33 is secured to the inner housing 31 by an interference fit or adhesive bonding. The optical signal modulated by the RF signal passes through the autofocus lens 34, where it is collimated and the beam spot is amplified. After the plug and corresponding contacts in the receptacle mate, expanded optical fiber transmission is achieved. It should be noted that by adjusting the focal length of the autofocus lens 34, the receptacle is compatible with both single-mode and multimode optical fibers, such as 9 / 125 single-mode fiber, 50 / 125 multimode fiber, and 62.5 / 125 multimode fiber.

[0035] In certain embodiments, see Figure 1 、 Figure 3 and Figure 7 When the plug and socket need to be connected, the socket pin 12 is pressed downward and the connecting nut of the plug is rotated so that the pin 12 is guided into the rotating groove, thereby realizing quick plugging and unplugging of the plug and socket. It should be noted that the socket housing 1 is machined from metal and has good machinability, which can ensure product strength and processing accuracy. Stainless steel passivation and titanium alloy materials can be selected according to environmental requirements. In addition, the shell surface is designed with a threaded structure to reduce salt deposition in the marine environment and can adapt to harsh marine environments such as acid salt spray, acidic atmosphere, and mold.

[0036] In certain embodiments, see Figure 4 and Figure 5 The pin mounting plate assembly 2 includes a front pin mounting plate assembly 21 and a rear pin mounting plate 22. The front pin mounting plate assembly 21 is positioned with the rear pin mounting plate 22 via a positioning sleeve 23. The rear pin mounting plate 22 is fixed to the front pin mounting plate assembly 21 via a connecting screw 24 threadedly connected to the positioning sleeve 23. A sealing body 25 is bonded to the rear pin mounting plate 22. Specifically, the front pin mounting plate assembly 21 includes a front pin mounting plate 211 and a short positioning pin 212. The short positioning pin 212 is fixed to the front pin mounting plate 211 via an interference fit.

[0037] It should be noted that, see Figure 4 The pin mounting plate assembly 2 is provided with a mounting hole 27 that passes through the pin front mounting plate assembly 21, the pin rear mounting plate 22 and the sealing body 25, and the non-contact beam expanding optical fiber contact 3 is fixed in the mounting hole 27 by a claw 26.

[0038] See also Figure 1 The socket of the present invention cooperates with the positioning keys of the plug through the five positioning key slots 5 to position the socket, and has the functions of preventing oblique insertion and wrong insertion.

[0039] The present invention adopts a socket with a non-contact beam-expanding optical fiber contact 3 for transmitting optical signals modulated by radio frequency signals, so as to achieve the purpose of the socket's specific high return loss advantage, so that the socket can reduce signal reflection when transmitting signals, thereby reducing signal loss and improving the quality and stability of radio frequency signal transmission.

[0040] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
