As shown in fig. 2 and 3, in the unconnected state, one end of the female jumper conductor 150 is connected to and conducted with the female wire 110, and the other end is in contact with the female seal 180. The female jumper conductor 150 is embedded in the female housing 160. The female head film 140 is filled with hydraulic oil, and the hydraulic oil is filled in the oil cavity 162 through the female head oil cavity channel 161; the hydraulic oil is filled in the push plate oil chamber 194 through the push plate oil passage 191, and the internal space of the female housing 160 is filled in the push plate oil guide groove 194, and the spring 170 is soaked in the hydraulic oil. The male second crossover conductor 220 is embedded in the male sealing head 214, the male secondary oil chamber channel 215 connects the male secondary oil chamber 242 with the rear space of the male sealing head 214, the male main oil chamber channel 241 connects the rear space of the male sealing head 214 with the inner space of the male film 250, and the male film 250 and the male secondary oil chamber 242 are filled with hydraulic oil. The male first crossover conductor 230 is in conductive communication with the male lead 270 and is in contact with the male seal 214.

As shown in fig. 1, 2 and 3, the female conductor 110 and the male conductor 270 are cable conductors, the female conductor insulating layer 120 and the male conductor insulating layer 280 provide insulation protection for the cable conductors, and the female cable filler 130 and the male cable filler 290 basically fill the cable, so as to prevent the cable from being bent excessively and damaging the cable conductors. The male housing 260 is integrally connected to the outer layer of the cable, and the male housing runner 261 guides seawater to realize pressure balance when the male film 250 expands or searches.

As shown in fig. 1, 2, 4 and 5, when connected, the front end of the female housing 160 and the front end of the male inner housing 240 are brought together and seawater therebetween is squeezed, the extension shoulder 216 is pushed, the male extension 210 is pushed forward, and the male sealing head 214 pushes the female sealing head 180 and is inserted into the female housing 160. The male extension end 210 is pushed out to the position of the female film 140, and at this time, one end of the male second jumper conductor 220 contacts with the male first jumper conductor 230 and the other end contacts with the female jumper conductor 150, so that the male and female power conduction is realized. In the connection operation, after the male head extension end 210 is pushed to the designated position, the handle 213, the support 212 and the connecting rod 211 form a cam mechanism, the handle 213 is pressed while the connecting rod 211 presses the front end of the male head extension end 210, the female head bridging conductor 150 is extruded to be tightly attached to the male head second bridging conductor 220, meanwhile, the sufficient connection fastening force of the male head and the female head is ensured, and the male head and the female head are prevented from being disconnected in the ocean current disturbance process. The "S" shaped design of the air cavity 163, oil cavity 162 and female crossover conductor 150 facilitates the mating of the female crossover conductor 150 with the male second crossover conductor 220 when the front end is compressed. When the front end of the female housing 160 is pressed, the volume of the oil chamber 162 is changed, and the hydraulic oil is balanced in pressure by the female oil chamber channel 161.

As shown in fig. 3 and 5, the spring 170 is compressed as the female seal head 180 is pushed during the connection process, and the position restoration of the female seal head 180 is mainly pushed by the spring 170 during the connector pulling operation of the present invention. The spring 170 is in a compressed state when the male and female are not connected, and has a certain pre-tightening force but is less than the frictional force between the female seal head 180 and the female housing 160. The push plate 190 and the booster plate 101 are designed in view of the long life requirement of the present invention, as the spring 170 may not have the ability to fully restore the female seal head 180 when the connector is pulled out after a long period of operation. The power assisting plates 101 are hinged to each other at positions where they are slidably located in the housing power assisting plate slide grooves 165 and the power assisting plate slide grooves 192. One end of the booster plate 101 is hinged to the female housing 160 through a booster plate fixing shaft 164, and the other end is hinged to the female sealing head 180. The spring 170 is compressed and the booster plate 101 folds and pushes the push plate 190 outward, and during the process of pulling out the male, if the female sealing head 180 does not return to the original position, the push plate 190 can be clipped from both sides, and during the process, the booster plate 101 will push the female sealing head 180 to return. During the pushing of the push plate 190 out of the nip, hydraulic oil flows in the female housing 160, between the push plate oil chamber 194 and the interior of the female film 140 through the push plate oil passage 191 and the push plate oil guide groove 193. During plugging, hydraulic oil flows in front of the front and rear portions of the male auxiliary oil chamber 242 and in front of the inner space of the male film 250 through the male auxiliary oil chamber flow passage 215 and the male main oil chamber flow passage 241.
