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

An underwater wet connector is a power transmission and communication optical cable connecting device which can be applied to an underwater observation network, an underwater production system and the like. The underwater wet connector is different from an underwater dry connector in that the underwater dry connector can realize repeated underwater plugging and unplugging, and the underwater plugging and unplugging electricity-leakage-free function provides guarantee for underwater equipment maintenance and necessary control and power circuit switching.

The production and the manufacture of the underwater dry connector are realized at present in China, the research on the underwater wet connector is also primarily developed, but the product manufacture of the underwater wet connector still belongs to the blank field, and the increase of the related research work intensity is very important.

Disclosure of Invention

The invention provides an underwater wet connector which can realize repeated pulling and inserting of the underwater connector and simultaneously guarantee the sealing and corrosion prevention requirements of a metal conductor of the connector in a disconnecting state and a connecting state.

The solution scheme adopted by the invention for solving the technical problem is as follows: the invention comprises a male head and a female head, wherein the male head comprises a male head shell, a male head cable filler, a male head extending end, a male head sealing head, a male head first bridging conductor, a male head second bridging conductor, a male head lead insulating layer, a male head lead and a male head grounding wire. The female head comprises a female head shell, a female head sliding plug, a female head grounding wire, a female head first bridging conductor, a female head second bridging conductor, female head cable filling, a female head wire and a female head wire insulating layer.

The male head second bridging conductor is embedded in the inner side of the male head extending end, the male head first bridging conductor is embedded in the front end of the male head shell and is connected and conducted with a male head lead, and the male head sealing head is assembled in the male head extending end and is made of rubber materials and assembled in an interference mode. The female first second cross-over conductor is embedded inside the female sliding plug, and the female first cross-over conductor is embedded in the front end of the female shell and is connected and conducted with a female wire.

The male and female jumper conductors and the lead are isolated from the external seawater in the unconnected state, and the insulation state is kept. In the connection process, the male shell is firstly contacted with the front end face of the female shell to extrude seawater between the end faces. The male head extension end is pushed backwards, the male head extension end and the male head sealing head are inserted into the cavity of the female head shell, seawater in the cavity of the shell is discharged from a cavity runner on the female head shell, and after the male head extension end is completely pushed, the first cross-connection conductor of the male head is connected and conducted with the second cross-connection conductor of the male head. Promote female first sliding plug, female first sliding plug promotes public first sealed head and inserts public first extension end simultaneously in the middle of, female first second cross-over connection conductor switches on with public first second cross-over connection conductor, the first cross-over connection conductor connection of female first after female first sliding plug impels completely, and public first, female first power switch on this moment. When the connector is pulled out, the female head sliding plug is pushed back firstly, then the male head extending end is pushed back, and after the connector is pulled out, the male head conductor and the female head conductor are in a sealed state.

The invention has the beneficial effects that: the invention can ensure that the joint keeps sealed in the disconnected and connected states, only needs to push the joint device in the plugging and unplugging process, and has simple operation and reliable sealing.

Detailed Description

As shown in fig. 2, the male lead 120 is connected to the male first crossover conductor 160, the female lead 250 is connected to the female first crossover conductor 230, the male lead insulation layer 130 and the female lead insulation layer 260 ensure lead insulation, and the male ground wire 110 and the female ground wire 270 are made of conductive rubber for ground protection in a leakage state. The male extension 150 and the female slip plug 220 are in an initial position in the disconnected state.

As shown in fig. 1, 2 and 3, during the connection process, the male housing 140 is in end-face contact with the female housing 210, and then the extension end shoulder 151 of the male extension end 150 is pushed, the male extension end 150 is pushed into the housing cavity 211 of 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, seawater in the housing cavity 211 is discharged from the cavity runner 212 during the pushing process, the cavity runner 212 is squeezed and sealed by a rubber block, and the seawater flows out from the rubber block gap when a pressure difference occurs. After the male extension 150 is pushed into the bottom of the housing cavity 211, the male first jumper conductor 160 is connected to the male second jumper conductor 180. And then the sliding plug shoulder 223 is pushed, the female sliding plug 220 and the female second crossover conductor 240 move together along the female slide way 213, the female sliding plug 220 pushes the male sealing head 170 to move, and when the front end of the sliding plug cover plate 221 moves to the front end position of the female slide way 213 in the moving process, seawater in the female slide way 213 flows out from the sliding plug runner 222. Continued forward movement of the plug cover 221 to the cavity channel 212 position will block the cavity channel 212 and seal the position. When the female sliding plug 220 is pushed to the end of the female sliding way 213, the male sealing head 170 is pushed back to the inside of the male housing 140, the female second bridging conductor 240 is connected and conducted with the female first bridging conductor 230, the female second bridging conductor 240 is connected and conducted with the male second bridging conductor 180, and at this time, the connectors are connected and powered on. The connector is pulled out by pushing the slip plug shoulder 223 back, pushing the female slip plug 220 back into place, and then pushing the extension end shoulder 151 back, pushing the male extension end 150 back into the male housing 140.
