A Rolling Sealing Insertion Mechanism for Photoelectric Connectors in Exceptional Environment

Abstract

The invention discloses a photoelectric connector rolling sealing plug-in connection technology under harsh environment. The technology is suitable for hot plugging of a connector under harsh environment, such as deep water and oil gas. The sealing technology overcomes defects that a rolling sealing structure of the connector normally needs to be opened or closed through a penetration key betweena socket and a plug and the exposed key is liable to be lost, and meanwhile, the sealing technology has the advantage that the structure is simpler than an eccentric wheel orbital transfer type sealing structure. The socket and the plug of the connector of such type both have two sidewalls and a relatively slidable plugging chamber distributed in the middle, at least one cylindrical sealing structure is respectively embedded at an end part of the socket and the plug, a sealing column has a transverse penetration hole, sliding shafts are located at two sides, and at least one side has a rollingshaft of different radius. A guide groove and a U-shaped groove in cooperation with the sliding shafts and the rolling shaft are respectively embedded in the sidewalls, different positions of surfaces of two sides of the U-shaped groove respectively have one segment of external convex rolling friction band used for controlling a rotation direction of a pair of the sealing columns, and consequently, on and off of the socket and the plug is realized.

Description

technical field [0001] The invention relates to a live plugging and unplugging technology of a photoelectric connector in an extraordinary environment, in particular to a rolling sealing insertion mechanism of a photoelectric connector in an extraordinary environment. Background technique [0002] With the further understanding of marine resources and their environment brought about by scientific and technological progress, marine engineering and marine development have entered a new stage. Subsea oil and gas fields, exploration and exploitation of seabed mineral deposits, and tidal power generation have formed some emerging marine development industries. Planning and establishing a submarine observation network is a necessary way to further understand and manage the ocean. Relying on the monitoring network, on the one hand, it can forecast natural disasters such as submarine earthquakes and tsunamis, realize disaster reduction and prevention, and also realize monitoring of ...
