An underwater wet connector

Abstract

An underwater wet connector relates to an underwater wet connector that can be used for seabed observation networks, underwater production systems, etc. The wet connector includes a male head and a female head. Sealing heads are arranged at the front ends of the male and female heads. The female sealing head and the male sealing head are made of rubber material and are precisely assembled. The connector end can be sealed in an unconnected state to avoid contact with seawater in an unconnected state, which may cause corrosion of wires or metal conductors. At the same time, the sealing head adopts interference assembly to ensure that the male and female joint conductors are sealed relative to the external seawater during the insertion process. During the connection process, the male shell is inserted into the female shell and the sealing plug is pushed to move at the same time. The male sealing head is held in place by the female sealing head. During the insertion process, the built-in jumper conductor of the male head moves synchronously with the male shell until it contacts the female joint conductor and is energized. The device can achieve a highly reliable underwater wet connection.

Description

Technical Field

[0001] The invention relates to an underwater wet connector, in particular to a wet plug-in connection device for underwater communication and power transmission cables. Background Art

[0002] The development of marine engineering has promoted the development of the underwater industry. Underwater connectors are key parts of underwater production systems, underwater observation networks, etc., and are mainly used for underwater power transmission, signal transmission, etc.; the development of underwater wet connectors is a key direction in the field of marine engineering.

[0003] Underwater wet connectors require waterproofing and reliable watertightness. The main technical challenge is that they are inaccessible to humans. They involve areas such as corrosion protection and sealing, and require multidisciplinary design and research, which is also the difficulty in the current development of wet connectors. Summary of the invention

[0004] In order to solve the problem of underwater plugging and unplugging of connectors, the present invention proposes an underwater wet connector, which can realize repeated plugging and unplugging underwater, while ensuring that the cable will not be corroded when treated underwater for a long time in a connected or disconnected state.

[0005] The solution adopted by the present invention to solve its technical problem is: the present invention is divided into two parts, a male connector and a female connector. The male connector consists of a male connector shell, a male connector cable filling, a male connector wire insulation layer, a male connector grounding wire, a male connector wire, a male connector sealing head, and a male connector jumper conductor. The female connector consists of a female connector shell, a female connector cable filling, a female connector wire insulation layer, a female connector grounding wire, a female connector wire, a female connector sealing head, a female connector conductor, and a sealing plug.

[0006] Insulating sealing heads are designed at the front end of the male and female wires. The female sealing head is fixed on the female connector conductor by vulcanization. The female and male sealing heads are made of rubber materials and precisely assembled. The connector end can be sealed when not connected, which can avoid contact with seawater in the unconnected state, resulting in corrosion of wires or metal conductors. At the same time, the sealing head is precisely assembled to ensure that the male jumper conductor and the female connector conductor are sealed relative to the external seawater during the insertion process. During the connection process, the male shell is inserted into the female shell and the sealing plug is pushed to move. The male sealing head is held in place by the female sealing head. During the insertion process, the built-in jumper conductor of the male moves synchronously with the male shell to connect with the female connector conductor.

[0007] The beneficial effects of the present invention are as follows: the present invention can ensure that the connector conductor and the wire are sealed to the external seawater when the connecting plug is working or disconnected underwater, ensure the high reliability of underwater wet connection, allow multiple plugging and unplugging operations, and ensure the number of plugging and unplugging operations required by the work.

DETAILED DESCRIPTION

[0014] Depend on Figure 1 , 2 As shown in Figure 3, in the unconnected state, the male sealing head 107 and the female sealing head 202 are in the initial position, and the male wire 103, the female wire 205, the male jumper conductor 105, and the female connector conductor 203 are in a sealed state. The male jumper conductor 105 and the female connector conductor 203 are connected and conductive with the male wire 103 and the female wire 205 respectively. The male wire insulation layer 104 and the female wire insulation layer 206 ensure that the male wire 103 and the female wire 205 are insulated from the outside world in the working state. The male grounding wire 106 and the female grounding wire 208 use conductive rubber material to act as grounding wires in the leakage state. The male cable filler 102 and the female cable filler 207 prevent the cable from being excessively bent and causing damage to the internal structure.

[0015] Depend on Figure 1 , 2As shown in Figures 3, 4, and 5, during the connection process, the male housing 101 first contacts the sealing plug 204, and the male sealing head 107 contacts the female sealing head 202, squeezing the seawater on the contact surface. Then the male housing 101 is inserted into the female housing 201 and pushes the sealing plug 204 to move. During this process, the seawater originally in the female housing 201 is discharged from the sealing plug drain hole 2042. At the same time, the male sealing head 107 is supported by the female sealing head 202, so the male sealing head 107 is not inserted into the female housing 201 together with the male housing 101. During the insertion of the male housing 101, the male sealing head convex shoulder 1071 slides relative to the male housing 101 along the male sealing head slideway 1011. 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. When the connector is pulled out, the relative positions of the male sealing head shoulder 1071 and the female housing 201 are fixed, and the sealing plug shoulder 2041 is pushed in the opposite direction to the installation direction while the male housing 101 is pulled out.
