Technical Field

[0001] The invention belongs to the technical field of connectors, and in particular relates to a multi-signal hybrid high-speed integrated beam-expanding optical fiber plug. Background Art

[0002] According to the demand, circular connector products generally only have single electrical signal transmission products, with the maximum shell number of 25, and do not have quick plug-in installation and anti-vibration functions. Therefore, they are greatly limited in integrating multiple signal transmissions; at the same time, existing circular connectors need to meet special use environments and have high signal transmission requirements. The existing connectors are not highly integrated and cannot meet the requirements of transmitting multiple signals such as optical signals, power signals, and buses based on one connector at the same time. Summary of the invention

[0003] In view of this, the present invention provides an ocean-resistant multi-signal hybrid high-speed integrated beam-expanding optical fiber plug, which can realize simultaneous high-speed transmission of optical / power signals and can be used in harsh environments.

[0016] Two 8#1553B signal cavities and two 8#1394B bus signal cavities are centrally symmetrically distributed with the central axis as the center, and are arranged on the periphery of the second group of six 16#power supply signal cavities.

[0017] Furthermore, the central axes of the three 16# power signal cavities, the two 12# RF signal cavities, and the two 12# cavities are located on the first cross section of the insulator component; and the central axis of the insulator component is located on the first cross section.

[0018] Furthermore, the central axes of the three 16# power signal cavities and the two 12# cavities are located on the second cross section of the insulator component; and the central axis of the insulator component is located on the second cross section.

[0021] Furthermore, the insulator assembly includes a wire sealing body, a rear insulator for the jack, and a front insulator for the jack; wherein the wire sealing body, the rear insulator for the jack, and the front insulator for the jack are coaxially bonded and fixed in sequence.

[0022] Furthermore, each hole cavity is provided with a socket claw for fixing each socket.
