A plug
The sealing performance of the plug depends on the sealing effect of the inner housing assembly, and the working principle of the inner housing assembly is shown in an inner housing assembly diagram.
One end of a jack component (49) in the inner shell component is fixed in a hole of the front base (43) in a sealing way, and the other end of the jack component is fixed in a hole of the rear base (55) in a sealing way; the sliding pin (90) in the jack assembly (49) is made of high-strength insulating material, and the sliding pin is sealed with the inner cavity of the jack assembly (49) through the long rubber inlet sleeve (91); the jack assembly (49) is connected with the cable (2), and the cable (2) realizes the sealing between the plug and the cable (2) through the tail pipe assembly (12), so that seawater can not enter the jack assembly (49) when the plug (4) is filled with water. The inner shell (66), the front base (50), the front liner (51) and the rear liner (54) in the inner shell assembly (7) are integrally sealed by adopting elastic deformation of a rubber sealing ring and a rubber die (52).
The sealed cavity of the plug inner shell assembly (7) is filled with insulating oil, and the jack assemblies (49) are distributed in the cavity (7004) and the cavity (7005) which are filled with the insulating oil. In the water inlet process of the plug (4), the external pressure is larger than the inside of the oil cavity, seawater enters the outside of the cavity (7001) through the pressure balance hole (661), and the pressure of the seawater causes the rubber mold (52) of the rear liner (54) to deform inwards; the oil pressure in the cavity (7001) and the cavity (7002) is increased, and the insulating oil flows and drives the rubber die (52) of the pressure front liner (51) to move inwards; the oil pressure of the cavity (7003) is increased, and insulating oil enters the cavity (7004) through the hole (511), so that the pressure of the cavity (7004) and the pressure of the cavity (7005) tend to be balanced; and then the jack assembly (49) is driven to open the inlet valve (81), and insulating oil in the cavity (7004) enters the cavity of the jack assembly (49) through the inlet valve (81), so that the balance of the internal pressure and the external pressure of the oil cavity of the plug (4) is finally achieved.
In the water outlet process of the plug (4), the internal pressure of the oil cavity is larger than that of the outside, and the pressure of the cavity (7004) and the cavity (7005) is sequentially released by means of the rubber die (52) of the front liner (51), the cavity (7002) and the cavity (7003) by means of the rubber die (52) of the rear liner (54) and the cavity of the jack component (49) by means of the outlet valve (86), so that the pressure balance between the inside and the outside of the oil cavity is kept.
In the water inlet and outlet processes and in the underwater non-working state, the pressure balance system adjusts the pressure inside the oil cavity to be consistent with the external seawater pressure at any time, so that no pressure difference exists between the inside and the outside of the oil cavity. Because the pressure balance system is designed in the plug (4), the pressure in the plug sealing cavity is consistent with the external seawater pressure, and the sliding pin (90) in the jack assembly can not be retracted into the jack assembly (49) by the seawater pressure in the deep sea environment, so that the plug (4) is better ensured to be sealed.
B socket
The socket (5) theory of operation, contact pin subassembly (34) are fixed in base (47), adopt the sealing washer to seal between contact pin subassembly (34), base (47) and socket inner shell (48), and after the tail end bonding wire of contact pin subassembly (34) embeds epoxy (43) in the casing, realizes the whole seal of socket inner shell (48), base (47) and contact pin subassembly (34), has guaranteed that the sea water can not enter into inside socket (5) from socket (5) insertion end under deep sea environment. The socket (5) is connected with the underwater equipment (2) through a flange plate and is sealed by adopting multiple sealing rings.
2) Underwater plug
A inserting process
When the electrical connector is plugged in, the ROV (3) operates the handle device (32) to align the safety limiting block (72) of the plug (4) with the alignment groove (5A) of the socket (5) and push the handle device (32) forwards, and a plurality of locking hooks (26) on the inner shell (66) of the plug fall into the annular groove (5B) of the socket to lock the plug (4) and the socket (5). When the socket is plugged, the contact pin assembly (34) of the socket (5) is contacted with the sliding pin (90) of the plug (4) to squeeze out seawater in the concave circle (904) of the sliding pin, the contact pin assembly (34) of the socket (5) is inserted forwards, the sliding pin (90) is jacked into the inner cavity of the jack assembly (49), the spring (84) is compressed, and the front section (342) of the contact pin at the conductive part of the contact pin assembly (34) is contacted with the slotted jack (82) to complete electric connection.
When the contact pin assembly (34) of the socket (5) is inserted, the cavity pressure of the jack assembly (49) is increased, an outlet valve (86) of the jack assembly (49) is opened to be communicated with the cavity (7004) and the cavity (7005), and insulating oil in the jack assembly (49) flows to a jack rear section (87) under the action of pressure so as to flush the slotted jack (82), so that the reliability of electric contact is improved; simultaneously, insulating oil enters the cavity (7004) and the cavity (7005), the pressure of the cavity (7004) and the pressure of the cavity (7005) are increased, the rubber die (52) of the front liner (51) are forced to deform outwards, the oil pressure of the cavity (7002) and the oil pressure of the cavity (7003) are increased, the rubber die (52) of the rear liner (54) deforms outwards, and the pressure balance between the inside of the oil cavity and the outside seawater is realized. In the plugging process, the pin assembly (34) of the socket (5) replaces the sliding pin (90) to form dynamic seal with the inlet sleeve (91); after the insertion, the insulating part (343) of the pin assembly (34) is tightly sealed with the inlet sleeve (91) to seal the oil cavity.
B separation process
The ROV (3) pulls the handle device (32), the locking assembly (8) moves backwards together with the handle device (32), the locking hook (26) on the inner shell (66) moves radially under the guidance of the contact inclined surface (712) of the unlocking sleeve (71), the locking hook (26) opens, and the plug (4) is unlocked with the socket (5); continuing to pull the handle assembly (32) rearward, the inner housing (66) will move together, disengaging the jack assembly (49) from the pin assembly (34) and effecting the electrical signal disconnection.
When the contact pin assembly (34) is pulled out outwards, the pressure of the cavity in the jack assembly (49) is reduced, an inlet valve (81) of the jack assembly (34) is opened, insulating oil in the cavity (7004) and the cavity (7005) enters the jack assembly (49), and the pressure is sequentially supplemented in the cavity (7003), the cavity (7002) and the cavity (7001), so that pressure balance is regulated. Simultaneously, the spring (84) pushes the sliding pin (90) to synchronously move with the contact pin assembly (34) and restore to the original position to be sealed with the inlet sheath (91) again so as to seal the oil cavity.
C pressure equalization
The pressure balance system of the plug adopts a leather bag structure and double balance films for adjustment, and has quick response and high reliability. The pressure balance system enables the connector to be plugged and pulled out with the same force in any water depth, and ensures that the plugging and pulling of the electric connector are not limited by the water depth. Moreover, in this state, the penetration of water is much less than in the presence of a large pressure gradient, improving the sealing properties of the product.
D live plug
The rear end of the conductive part (342) of the pin assembly (34) is provided with an insulating part (343). When the plug (4) and the socket (5) are inserted, the conductive part (342) of the pin assembly reaches the oil cavity of the jack assembly (49) at first, the insulating part (343) is sealed with the inlet sleeve (91), and the conductive part (342) of the pin assembly is communicated with the slotted jack (82) of the jack assembly (49) for conduction along with the insertion of the pin assembly (34). When the contact pin assembly is pulled out, the conductive part (342) of the contact pin assembly is firstly separated from the slotted jack (82) and then exits the oil cavity, and the sliding pin (90) in the jack assembly (49) is reset to be sealed with the inlet sleeve (91). The electric connection and disconnection of the connector are carried out in the oil cavity of the jack assembly (49), so that the electric arc generated during connection and disconnection can be effectively annihilated, and live plug-in and plug-out are realized.
3) Operating state
The electric connector works in a deep sea environment, after the electric connector is plugged, the conductive part (342) of the pin assembly is positioned in the oil cavity, the part exposed in the sea water is coated with high-strength insulating materials, the insulating part (343) of the pin assembly (34) replaces the sliding pin (90) of the plug (4) to be sealed with the inlet sleeve (91) of the jack assembly (49), the sea water is blocked outside the inlet sleeve (91) of the jack assembly (49), the sealing effect is achieved, and the electric performance requirement of a product is guaranteed.

In summary, the specific implementation process of the invention is as follows:
As shown in fig. 1 and 18, after the rear section 41 of the pin of the socket 5 is welded to the underwater device by a wire, the heat shrinkage tube processes the welding spot portion of the rear section 41 of the pin, and the socket 5 is fixedly connected with the underwater device 6 by a screw through the flange 45, so that in order to facilitate the ROV operator to observe the alignment socket 5, the alignment groove 5A of the socket 5 is installed upwards when the socket 5 is installed, and the protective cover 33 must be removed from the socket 5 before the socket 5 is installed underwater.
According to the length of the underwater equipment 6 from the surface system 1, a certain length of the cable 2 is cut, and one end of the cable 2 is connected with the surface system 1 in a wiring way. The other end of the cable 2 is in wire welding connection with the jack assembly 39 of the plug 4, the cable is sequentially provided with the limiting ring 10, the compression screw sleeve 11, the cable shield 31, the tail pipe assembly 12, the cable pressing ring 23 and the knurled nut 22, the knurled nut 22 and the cable clamping ring 23 compress the cable 2 to increase the connection firmness of the cable (2), and the cable 2 and the connector on the rear section 87 of the jack at the tail of the jack assembly 39 are subjected to encapsulation treatment by a heat shrinkage tube after being welded, so that the welding spot firmness is increased, and a certain sealing effect is achieved. Encapsulating epoxy resin at the core and the bonding wire of the cable 2; the entrance of the cable 2 is sealed by embedding polyurethane elastomer between the sheath 21 and the cable; the sheath 21 is tightened with the vulcanized tailpipe assembly 12 by the buckles 30, 31. Finally, the tail tube assembly 12 of the connected and vulcanized cable 2 is fixedly connected to the inner housing 66 of the inner housing assembly 7 by the compression nut 11.
The ROV3 manipulator clamps the handle device 32 of the plug 4, the ROV3 carries the plug 4 for installing the cable 2 to the installation position of the underwater socket 5, an operator aligns the installation limiting block 72 on the locking component 8 of the plug 4 with the alignment groove 5A of the socket 5, the outer circle of the inner shell 48 of the socket 5 and the inner hole of the inlet ring 69 of the locking component 8 of the plug 4 are on the same axis, the operator pushes the handle device 32 of the plug 3 forwards, the boss 662 of the inner shell on the socket 4 enters into the alignment groove 5A of the socket 5, the outer circle of the inner shell 66 overcomes the elasticity of the locking hook 26 and the elasticity of the safety spring 70, the locking hook 26 is outwards spread, and the plug 4 continues to move towards the socket 5. The jack assembly 49 of the plug 4 comes into contact with the pin assembly 34 of the receptacle 5. The contact of the pin assembly 34 of the socket 5 with the sliding pin 90 of the plug 4 squeezes out the seawater in the concave circle 904 of the sliding pin, the pin assembly 34 of the socket 5 is inserted forward, the sliding pin 90 is jacked into the inner cavity of the jack assembly 49, the spring 84 is compressed, and the conductive part 342 of the pin assembly 34 is contacted with the slotted jack 82, so that the electrical connection is completed.
