Description

Technical Field

[0001] The invention belongs to the technical field of connectors, and in particular relates to a connector capable of underwater electromagnetic separation. Background Art

[0002] In the shipbuilding field, optical cables / electric cables are required to transmit signals between the semi-submersible platform / horizontal control console and the underwater submersible / mine. After the submersible dives to a specified depth, it will be required to cut off the transmission cable between the underwater submersible and the semi-submersible platform to facilitate the underwater submersible to perform subsequent tasks on its own. At present, domestic shipbuilding research and development units all cut off the transmission cable between the semi-submersible platform and the underwater submersible by directly physically cutting off the optical cable / electric cable / transmission cable through underwater mechanisms.

[0003] Although electromagnetic separation, electric explosion separation and mechanical separation can be used to separate the connectors in underwater environments and disconnect the transmission cable, the underwater wet plug connectors are limited in size, such as large size and low node arrangement density. The connector contacts can only use conventional pin and socket matching methods to minimize the product size while arranging as many contacts as possible to improve product applicability.

[0004] However, conventional pins and sockets are mostly made of copper alloys and other low-conductivity alloys as the base material. Although the corrosion resistance of the base surface can be improved through plating treatment, the current contact pairs that can meet the needs of connector separation and long-term immersion in seawater for reuse are not only complex in process and high in cost, but also have the problem of corrosion of the contacts in the seabed environment and the adhesion and accumulation of debris, especially on the socket end, which will make it impossible for the socket to be cleaned a second time to meet the needs of reuse.

[0005] The patent document with announcement number CN109787027A discloses a rotary underwater wet plug-in optoelectronic composite connector, including a socket and a plug that matches it; the plug body is the plug cavity, and the plug optoelectronic plug core is penetrated inside; the socket body is the socket intermediate sleeve, which forms the socket cavity with the socket end face and the socket rubber partition, and the socket optoelectronic plug core is penetrated inside. The plug and the socket are connected by the protrusion in the round tube of the socket end face and the spiral groove on the surface of the central axis inside the plug, so that the linear motion between the plug and the socket is converted into the common rotational motion of the two end faces, thereby making way for the insertion of the pins to achieve connection.

[0006] The patent document with announcement number CN112803193A discloses an optoelectronic hybrid watertight connector, including a plug and a socket, the plug including a plug shell and a transfer shell, a high insulator, a high insulation pressure plate, and a jack contact are installed in the plug shell, and the socket includes a socket shell, a short insulator, a short insulation pressure plate, and a pin contact are installed in the plug shell. The connector shell adopts O-rings, stuffing boxes, and vulcanization to protect the internal contacts from reliably docking at a depth of up to 6,000 meters underwater. The connector adopts epoxy adhesive to fix the insulating plate and the shell, which can make the connector contacts dock with high precision and make the connector have good anti-vibration function. The optical contacts and electrical contacts configured in the connector are basically the same in external dimensions and can be replaced, so that the connector can be flexibly configured with optoelectronic channels. The optical contact jack of the connector is equipped with a spring, and there is no spring in the pin. When docking, the single end can float, so that the connector has a smaller insertion loss.

[0007] However, the above patent does not disclose the technical feature that some parts at the jack end and the plug end can be replaced so that the connector can be reused. Summary of the invention
