An underwater wet connector relates to an underwater wet connector which can be used for a submarine observation network, an underwater production system and the like. This wet connector includes public head and female head, and public, female head front end set up sealed head, and the sealed head of female head and public first sealed head use rubber materials and adopt precision assembly, can guarantee under the unconnected state that the connector end is sealed, can avoid contacting the sea water under the unconnected state and lead to electric wire or metallic conductor to corrode, and sealed head adopts interference fit can guarantee that the joint conductor of male head and female head is sealed relative outside sea water in the insertion process simultaneously. The male shell is inserted into the female shell in the connection process, the sealing sliding plug is pushed to move at the same time, the male sealing head is propped against the female sealing head to be unchanged, and the built-in bridging conductor of the male plug and the male shell synchronously move to be in contact with the female connector conductor to be electrified in the insertion process. The device can realize the underwater wet connection with high reliability.

Description

Underwater wet type connector

Technical Field

The invention relates to an underwater wet connector, in particular to a wet plugging and unplugging connecting device for an underwater communication and power transmission cable.

Background

The development of ocean engineering advances the development process of the underwater industry, the underwater connector is a key part of an underwater production system, an underwater observation network and the like, is mainly used for the aspects of underwater power transmission, signal transmission and the like, the underwater wet connector is monopolized abroad at present, and the development of the underwater wet connector is a key direction in the field of ocean engineering.

Underwater wet connectors require water resistance and the device must be reliably water tight, with the major technical challenge being inaccessible. The wet connector is designed and researched by combining multiple disciplines in the fields of corrosion prevention, sealing and the like, and is also the difficulty of the development of the current wet connector.

Disclosure of Invention

The invention provides an underwater wet connector, aiming at solving the problem of underwater plugging and unplugging of a connector, which can realize repeated plugging and unplugging under water and simultaneously ensure that a cable cannot be corroded after being processed under water for a long time in a connected or disconnected state.

The solution scheme adopted by the invention for solving the technical problem is as follows: the invention is divided into a male head and a female head, wherein the male head consists of a male head shell, a male head cable filler, a male head lead insulating layer, a male head grounding wire, a male head lead, a male head sealing head and a male head bridging conductor, and the female head consists of a female head shell, a female head cable filler, a female head lead insulating layer, a female head grounding wire, a female head lead, a female head sealing head, a female head joint conductor and a sealing sliding plug.

Design insulating sealed head at public first and female first wire front end, female first sealed head adopts the vulcanization fixed mode to fix on female first joint conductor, and female first sealed head and public first sealed head use rubber materials and adopt accurate assembly, can guarantee under the unconnected state that the connector end is sealed, can avoid contacting the sea water under the unconnected state and lead to electric wire or metallic conductor to corrode, and sealed head adopts accurate assembly simultaneously can guarantee to insert the relative outside sea water of the joint conductor of in-process public first cross-over connection conductor and female head sealed. The male shell is inserted into the female shell in the connection process, the sealing sliding plug is pushed to move at the same time, the male sealing head is propped against the female sealing head to be unchanged in position, and the built-in bridging conductor of the male plug and the male shell synchronously move to be communicated with the female connector conductor in the insertion process.

The invention has the beneficial effects that: the invention can ensure that the joint conductor and the lead are sealed against external seawater when the connecting plug works underwater or is disconnected, ensure high reliability of underwater wet connection, allow multiple plugging and unplugging operations and ensure plugging and unplugging times required by work.

Detailed Description

As shown in fig. 1, 2, and 3, in the unconnected state, the male seal head 107 and the female seal head 202 are in the initial positions, and the male lead 103, the female lead 205, the male jumper conductor 105, and the female jumper conductor 203 are in the sealed state. The male jumper conductor 105 and the female tab conductor 203 are connected to and conducted with the male lead wire 103 and the female lead wire 205, respectively. The male lead insulation layer 104 and the female lead insulation layer 206 ensure that the male lead 103 and the female lead 205 are insulated from the outside in the working state. The male ground wire 106 and the female ground wire 208 are made of conductive rubber and function as ground wires in a leakage state. The male cable filler 102 and the female cable filler 207 prevent the cable from being bent excessively to cause damage to the internal structure.

As shown in fig. 1, 2, 3, 4 and 5, in the connection process, the male housing 101 is first contacted with the sealing sliding plug 204, and the male sealing head 107 is contacted with the female sealing head 202, so as to press seawater on the contact surface. Then the male housing 101 is inserted into the female housing 201 and pushes the sliding plug 204 to move, in this process, the seawater originally in the female housing 201 is discharged from the sliding plug discharge hole 2042, and meanwhile, the male sealing head 107 is supported by the female sealing head 202, so that the male sealing head 107 is not inserted into the female housing 201 together with the male housing 101, and the male sealing head shoulder 1071 slides along the male sealing head slideway 1011 relative to the male housing 101 during the insertion of the male housing 101. When the male housing 101 is inserted to the maximum position, the male jumper conductor 105 contacts the female connector conductor 203, and the connector is energized. Upon connector extraction, the relative position of the male seal head shoulder 1071 and the female housing 201 is fixed, pushing the seal slide plug shoulder 2041 in the opposite direction to installation while extracting the male housing 101.
