Description

A kind of detachable deepwater seal connector

Technical field

The utility model relates to electric connector fields, shield tail more particularly to a kind of deep water sealing plug and deep water sealing Department enclosure.

Background technique

Underwater Engineering and equipment technology field in ocean, it is underwater electrical as the mankind explore the quickening of exploitation ocean paces Equipment and device are widely used, for contacting the underwater electrically Important Components with water surface terminal device or power supply -- connect under water It connects device also gradually to grow up, and it is required increasingly to improve, gradually expand to 5MPa, 10MPa from 1MPa hydrostatic pressure requirements, Even higher hydrostatic pressure requirements.

Current most of deepwater seal connectors reduce most of sealing position, plug to the greatest extent to improve sealing reliability It is an integral structure, that is, omits tail accessory to exempt the sealing of plug and tail accessory binding site, plug casing tail end is very Long, to realize sealing and shielding to cable, axial arrangement size is bigger, and the processing of long shell structure acquires a certain degree of difficulty, by In no tail accessory, therefore it is unfavorable for realizing product versatility, modularization, and inconvenient maintenance；The depth of non-encapsulating tail accessory The general resistance to hydrostatic pressure power of water-tight connector is several meters of left and right (less than 0.1MPa), is not used to deep water occasion；Encapsulating type tail portion Attachment, although the sealing means part difficulty of processing is little and is easier to realize, its non-dismountable and maintenanceability is poor, in addition, Encapsulating hermetically sealed connector is after the environmental tests such as experience high/low temperature circulation, and sealing performance can decline, which is not suitable for work Make the big occasion of temperature change.

The sealing of connector and cable generally uses the side such as seal rubber protective case, vulcanization, encapsulating, O shape rubber seal Formula realizes sealing, and rubber protecting jacket disassembly, inconvenient maintenance, the modes such as vulcanization, encapsulating cannot achieve detachable maintaining, and O shape rubber Sealing ring is generally stringent to outside diameter of cable size, appearance requirement, and tolerance cannot be too big, and cable cannot have obvious fold along axial With it is rough and uneven in surface, otherwise may cause seal failure；When to realize sealed reliable, cable will be by biggish radial pressure, this Sample can aggravate the creep of cable cover(ing), act on using high/low temperature, and the creep of cable cover(ing) can be very serious and then occurs leaking existing As.

The deep water sealing electric connector of magnetic tape trailer department enclosure can install the hood of different structure form, to realize to different straight The sealing of diameter size cable assembles, is easy to maintenance, being advantageously implemented generalization, modularization.But it is therefore processed to cable shield Journey brings difficulty, this is because should realize sealed reliable in plug or socket and tail accessory junction, guarantee cable again Shielding is effectively overlapped with connector, with electromagnetic leakage, while in cable core and plug or socket after contact welding, cable Become an entirety with plug or socket, tail accessory is connect in seal process with plug or socket it to have displacement relatively, i.e., Tail accessory has displacement with respect to cable, so if the shielded layer of cable is fixed on tail accessory be it is unworkable, it is such as solid Determine onto plug or socket then to will increase the structure size of connector.
