Description

Technical Field

[0001] The present invention relates to an underwater wet connector, specifically a wet plugging and unplugging connection device for underwater communication and power transmission cables. Background Art

[0002] An underwater wet connector is a power transmission and communication optical cable connection device that can be applied to underwater observation networks, underwater production systems, etc. The underwater wet connector is different from the underwater dry connector in that it can achieve repeated plugging and unplugging underwater, and its function of not leaking electricity during underwater plugging and unplugging provides guarantee for the maintenance of underwater equipment and the switching of necessary control and power circuits.

[0003] Currently in China, the production and manufacturing of underwater dry connectors have been realized, and there have been preliminary progress in the research on underwater wet connectors. However, the product manufacturing of underwater wet connectors still belongs to a blank field, and it is very important to increase the intensity of relevant research work. Summary of the Invention

[0004] To meet the requirement of repeated plugging and unplugging of the underwater connector, the present invention proposes an underwater wet connector, which can achieve repeated plugging and unplugging underwater, and at the same time ensure the sealing and anti-corrosion requirements of the metal conductors of the connector in the disconnected and connected states.

[0005] The solution adopted by the present invention to solve its technical problems is: The present invention consists of two parts: a male head and a female head. The male head includes a male head housing, male head cable filling, male head extended end, male head sealing head, male head first jumper conductor, male head second jumper conductor, male head wire insulation layer, male head wire, and male head ground wire. The female head includes a female head housing, female head sliding plug, female head ground wire, female head first jumper conductor, female head second jumper conductor, female head cable filling, female head wire, and female head wire insulation layer.

[0006] The male head second jumper conductor is embedded inside the male head extended end, the male head first jumper conductor is embedded at the front end of the male head housing and is connected and conducted with the male head wire, and the male head sealing head is assembled inside the male head extended end, using rubber material and adopting interference fit. The female head second jumper conductor is embedded inside the female head sliding plug, and the female head first jumper conductor is embedded at the front end of the female head housing and is connected and conducted with the female head wire.

[0007] In the unconnected state, the male and female connectors' cross-connecting conductors and wires are isolated from the external seawater and maintain an insulating state. During the connection process, the male connector housing first contacts the front end face of the female connector housing, squeezing the seawater between the end faces. Then, the extended end of the male connector is pushed. The extended end of the male connector and the sealing head of the male connector are inserted into the cavity of the female connector housing, and the seawater in the cavity of the housing is discharged through the cavity flow channel in the upper part of the female connector housing. After the extended end of the male connector is fully pushed in, the first cross-connecting conductor of the male connector is connected and conducts with the second cross-connecting conductor of the male connector. The sliding plug of the female connector is pushed, and the sliding plug of the female connector pushes the sealing head of the male connector to be inserted into the extended end of the male connector at the same time. After the sliding plug of the female connector is fully pushed in, the second cross-connecting conductor of the female connector is connected and conducts with the second cross-connecting conductor of the male connector and the first cross-connecting conductor of the female connector. At this time, the power supply of the male and female connectors is conducted. When the connector is unplugged, first push back the sliding plug of the female connector, and then push back the extended end of the male connector. After unplugging, the conductors of the male and female connectors are in a sealed state.

[0008] The beneficial effects of the present invention are as follows: The present invention can ensure that the joint remains sealed in both the disconnected and connected states. During the plugging and unplugging process, only the joint device needs to be pushed, and the operation is simple and the sealing is reliable. Brief Description of the Drawings

Detailed Embodiments

[0013] As Figure 2 shown, the housing 140 of the male connector is the front-end component of the male connector, and the slideway 141 of the male connector included therein serves as the moving path of the extended end 150 of the male connector.

[0014] As Figure 2 shown, the extended end 150 of the male connector is the moving component of the male connector, and the shoulder 151 of the extended end included therein is designed to facilitate the operation of its movement.

[0015] As shown Figure 2 in Figure 2 , the female head housing 210 is a front-end component of the female head, which includes a housing cavity 211, a cavity flow channel 212, and a female head slideway 213. The cavity flow channel 212 is designed to facilitate drainage during connection.

[0016] As shown Figure 2 in Figure 2 , the female head sliding plug 220 is a moving component of the female head, which includes a sliding plug cover plate 221, a sliding plug flow channel 222, and a sliding plug shoulder 223. The sliding plug shoulder 223 is designed to facilitate the operation of its movement.

[0017] As shown Figure 2 in Figure 2 , the male head wire 120 is connected and conducted with the male head first jumper conductor 160, the female head wire 250 is connected and conducted with the female head first jumper conductor 230, the male head wire insulation layer 130 and the female head wire insulation layer 260 ensure wire insulation, and the male head ground wire 110 and the female head ground wire 270 are made of conductive rubber material to provide ground protection in the event of leakage. In the unconnected state, the male head extension end 150 and the female head sliding plug 220 are in the initial positions.

[0018] As shown Figure 1 and 2As shown in FIGS. 3, during the connection process, the end faces of the male housing 140 and the female housing 210 are in contact. Subsequently, the extension shoulder 151 of the male extension end 150 is pushed, and the male extension end 150 is pushed into the housing cavity 211 on the female housing 210 along the male slideway 141. At this time, the male sealing head 170 in interference fit with the male extension end 150 moves together with the male extension end 150. During the pushing process, the seawater in the housing cavity 211 is discharged through the cavity flow channel 212. The cavity flow channel 212 is sealed by the extrusion of the rubber block. In the case of a pressure difference, the seawater flows out through the gap of the rubber block. After the male extension end 150 is pushed to the bottom of the housing cavity 211, the first male jumper conductor 160 is connected and conducted with the second male jumper conductor 180. Subsequently, the slide plug shoulder 223 is pushed, and the female slide plug 220 and the second female jumper conductor 240 move together along the female slideway 213. The female slide plug 220 pushes the male sealing head 170 to move. During the movement, when the front end of the slide plug cover 221 moves to the front end position of the female slideway 213, the seawater inside the female slideway 213 flows out through the slide plug flow channel 222. The slide plug cover 221 continues to move forward to the position of the cavity flow channel 212 to block the cavity flow channel 212 and seal this position. When the female slide plug 220 is pushed to the end position of the female slideway 213, the male sealing head 170 is pushed back into the male housing 140. The second female jumper conductor 240 is connected and conducted with the first female jumper conductor 230, and the second female jumper conductor 240 is connected and conducted with the second male jumper conductor 180. At this time, the connector is connected and powered on. When the connector is unplugged, first, the slide plug shoulder 223 is pushed in the reverse direction to push the female slide plug 220 back to its original position, and then the extension shoulder 151 is pushed in the reverse direction to push the male extension end 150 back into the male housing 140.
