Description

Technical Field

[0001] This invention belongs to the field of high-speed data transmission technology, specifically relating to a multi-signal hybrid high-speed integrated transmission rectangular fiber optic socket. Background Technology

[0002] Currently, various highly integrated signal transmission methods are available, including optical signal (FC-AE) bus, digital video signal, GJB289A bus signal, 1394B bus, video signal, discrete signal, and control signal. In particular, pneumatic connector products are involved, which are widely used in high-speed data transmission systems in fields such as optical fiber communication, optoelectronic information conversion, pneumatic equipment, ships, aviation, and aerospace.

[0003] Existing signal transmission products are generally circular connectors, which only have a single transmission function and lack quick plug-in / disconnection capabilities. This greatly limits their ability to integrate multiple signal transmissions. Furthermore, they cannot be used in special operating environments and cannot meet the high transmission requirements of demanding signals. Therefore, there is an urgent need for a multi-signal hybrid high-speed integrated transmission rectangular fiber optic socket to solve the above-mentioned problems. This socket would enable the transmission of optical and power signals while also adding the transmission of multiple bus signals, thus fulfilling the special requirement of high-speed transmission of multiple signals using a quick-disconnect rectangular connector. Summary of the Invention

[0004] In view of this, the present invention proposes a multi-signal hybrid high-speed integrated transmission rectangular fiber optic socket, which is applied to the field of high-frequency transmission equipment technology, and solves the existing technical problems of being unable to achieve multi-signal transmission, poor high-frequency signal transmission effect, lack of fast plug-in and unplug-out function, and limitation in harsh marine environments.

[0005] To achieve the above-mentioned technical objectives, the specific technical solution adopted by the present invention is as follows:

[0006] A multi-signal hybrid high-speed integrated transmission rectangular fiber optic socket includes a socket housing assembly and a first rectangular cavity and a second rectangular cavity disposed inside the socket housing assembly. The first rectangular cavity houses a first socket insulator assembly, an 8-pin coaxial connector, and a 12-pin coaxial connector. The first socket insulator assembly is formed by bonding twelve cores together. The 8-pin and 12-pin coaxial connectors are fixed to the first socket insulator assembly by a claw structure. The second rectangular cavity houses a second socket insulator assembly, a 16-pin connector, and a 22-pin connector. The 16-pin and 22-pin connectors are fixed to the second socket insulator assembly by a claw structure. Four potting grooves are provided on the front end face of the socket housing assembly, and all four grooves are potted with potting compound. A quick-release screw is provided on the socket housing assembly. The quick-release screw matches and connects with a floating structure sleeve disposed outside the socket housing assembly. The quick-release screw and the floating structure sleeve cooperate to achieve quick separation and docking of the socket housing assembly.

[0007] Furthermore, the socket housing assembly includes a square housing, with a first rectangular cavity and a second rectangular cavity both opening forward and positioned on the front end face of the square housing. A first socket insulator assembly is located at the bottom of the first rectangular cavity, and a second socket insulator assembly is located at the bottom of the second rectangular cavity. Potting grooves are distributed at the top, bottom, top, and bottom of the first and second rectangular cavities, respectively. The interiors of the four potting grooves are interconnected. During the potting process, potting compound is injected into one of the potting grooves, and the filling status of the potting compound is observed from the other three potting grooves until the potting compound cures.

[0008] Furthermore, the first socket insulator assembly includes a twelve-core sealing body, a twelve-core interface sealing body, and a twelve-core socket insulator, which are fixedly connected by adhesive.

[0009] Furthermore, the second socket insulator assembly includes a 65-core sealing body, a 65-core interface sealing body, and a 65-core socket insulator, which are fixedly connected by adhesive.

[0010] Furthermore, there are eight No. 8 coaxial pins in the first rectangular cavity, and the eight No. 8 coaxial pins are evenly distributed from top to bottom along the front end face of the first socket insulator assembly in groups of four. There are four No. 12 coaxial pins in the first rectangular cavity, and the four No. 12 coaxial pins are evenly distributed from top to bottom along the front end face of the first socket insulator assembly, and the four No. 12 coaxial pins are distributed between the two groups of No. 8 coaxial pins.

[0011] Furthermore, the No. 12 core sealing body is arranged around the rear end of the No. 8 coaxial pin and the No. 12 coaxial pin, the No. 12 core interface sealing body is located at the front end of the No. 8 coaxial pin and the No. 12 coaxial pin, and the No. 12 core socket insulator is arranged around the front part of the No. 8 coaxial pin and the No. 12 coaxial pin.

[0012] Furthermore, there are 25 No. 16 pins in the second rectangular cavity, and the 25 No. 16 pins are evenly arranged in groups of five in the lower part of the second rectangular cavity. There are 40 No. 22 pins in the second rectangular cavity, and the four No. 22 pins are evenly arranged in groups of ten in the upper part of the second rectangular cavity, and are distributed in four groups along the front end face of the second rectangular cavity.

[0013] Furthermore, a 65-core sealing body is arranged around the rear end of pins 16 and 22, a 65-core interface sealing body is located at the front end of pins 16 and 22, and a 65-core socket insulator is arranged around the middle of pins 16 and 22.

[0014] Furthermore, guide pins extending horizontally forward are provided at the four corners of the square housing, and all four guide pins are located outside the first rectangular cavity and the second rectangular cavity.

[0015] Furthermore, there are four quick-release screws, which are distributed at the four corners of the square housing. The four quick-release screws are located on the outside of the corresponding guide pins. The quick-release screws are fitted with conductive rubber pads, which are set in close contact with the front end face of the square housing.

[0016] By adopting the above technical solution, the present invention can also bring the following beneficial effects:

[0017] 1. This invention mentions a high-speed integrated rectangular fiber optic connector for multi-signal hybrid transmission. For high-speed integrated rectangular products that simultaneously transmit multiple signals such as optical signals, power signals, and bus signals, the connector's hole group is rearranged. While the interface size meets the rectangular requirement, the connector contact body is designed with non-contact fiber optic pins, multiple high-density integrated high-frequency contacts, and bus signal structures. This achieves the transmission of optical and power signals while adding the transmission of multiple bus signals, thus fulfilling the special requirements of the product's quick-release rectangular connector for high-speed transmission of multiple signals.

[0018] 2. The multi-signal hybrid high-speed integrated transmission rectangular fiber optic socket mentioned in this invention uses a direct-plug quick-connect connector interface, which is locked with screws and sleeves. The product hole group has been rearranged, which can realize 25 channels of 16# optical signals and power signals, 2 channels of 8# 1553B signal, 4 channels of 12# radio frequency signal, 40 channels of 22# electrical signals, 2 channels of 1394B bus signals, and 4 channels of Camelink bus signals in a smaller space. It realizes the simultaneous high-speed transmission of multiple signals such as optical signals, power signals, and bus signals, and realizes the quick-separation rectangular fiber optic socket characteristics of the product.

[0019] 3. The multi-signal hybrid high-speed integrated transmission rectangular fiber optic socket mentioned in this invention has the advantages of high transmission bandwidth and high transmission capacity in optical signal transmission. Moreover, it is small in size, light in weight, low in loss, good anti-interference, strong confidentiality, and not prone to crosstalk and interference. At the same time, the successful development of this connector not only enriches the variety of connector products and lays the foundation for the transmission of airborne buses, but also enables the connector to transmit power signals, 1553B signals, 1394B signals, FC fiber optic signals, and coaxial RF signals, etc. It has made a great contribution to the connector market and has a very promising application prospect.
