Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0022] The overall structure of the plug is as follows figure 1 , figure 2 shown. figure 1 , figure 2 Among them, 1 is the pre-assembled inner core body; 2 is the connecting nut; 3 is the plug shell, the plug shell 3 is provided with an outer cone structure C, and the outer cone structure is provided with two "O"-shaped sealing rings 31 ; 4, 5 are positioning pins; 6 is a locking screw; 8 is the tail assembly of the plug;

[0023] For the convenience and ease of the assembly and processing process, we make the inner core body 1 of the plug (see Fig. 5(a)) into a whole; when the connector plug is assembled, it is first assembled. In this embodiment, it mainly consists of a substrate 10, a ceramic ferrule 11, a spring 12, a spring seat 13, a ceramic jack 14, an outer sleeve 15 of the jack, a rear pressure plate 16, an inner core sleeve 17,...

Abstract

The invention relates to an optical cable connector, and provides an underwater optical cable connector, which is capable of meeting requirements on water tightness and tensile performance, and providing detachable and movable connection. The underwater optical cable connector is characterized in that mutually matched cone structures are arranged on a plug shell and a socket shell respectively sothat the plug shell and the socket shell can be in gapless sealing connection by means of insertion, a sealing connection structure is arranged between a plug and an optical cable, the space between the plug shell and a tensile taper sleeve is sealed by an 'O'-shaped sealing ring, and a sealing tail sleeve for sealing is formed in the space between the optical cable and a tail part of the whole plug by mean of integral die casting. The movable sealing connection structure is arranged between the plug and a socket of the underwater optical cable connector, the two shells are connected by cones, no gap is reserved between the inner cone and the outer cone, the space between the cones is sealed by the 'O'-shaped sealing ring, the inner cone and the outer cone are locked by a connecting nut, and the underwater optical cable connector is simple in structure, reliable in performance, extremely high in water pressure resistance and convenient in connection and detachment.

Description

technical field [0001] The invention relates to an optical cable connector, in particular to an optical cable connector mainly used in special occasions for connection between underwater facilities and optical cables. technical background [0002] So far, all countries in the world are paying attention to ocean development. In ocean development, optical fiber signal transmission facilities must be used. In addition, a large number of optical fiber communication is also required in rivers, lakes and seas, such as underwater robots, which are used to control various reservoirs and dams. For survey and inspection, it is also used to survey the bottom of the sea, the bottom of the lake, etc. For the salvage of sunken ships or other facilities sunk on the bottom of the lake or the bottom of the lake, sometimes underwater robots are also used to work. In military applications, such as: optical fiber hydrophone Underwater optical cable connectors are required for test applications ...
