The isolation sealing mechanism is provided with a channel in communication with the external environment on the insertion slot. When the insertion rod is inserted into the insertion slot, the water in the insertion slot can be gradually discharged from the channel due to the close fit of the isolation sealing part, which avoids the problem that the water pressure in the insertion slot prevents the insertion rod from being inserted, so that the connector can be normally used in the deep sea area with high pressure.

The isolation sealing mechanism of the present application is provided with a channel communicating with the water area on the slot. After the plug rod is extruded into the slot, due to the extrusion force, the water around the contact part is extruded towards the channel direction, so that the water in the slot is finally discharged to the outside from the channel, avoiding the formation of a closed pressure cavity in the slot, which causes the plug rod to be unable to be inserted.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solutions and advantages of the present application more clear, the present application will be further described in detail below combined with embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not used to limit the present application.

[0024] As Figures 1-5As shown, an isolation and sealing mechanism includes a first connection unit 1 and a second connection unit 2. The second connection unit 2 is provided with a slot 7 and a channel 11. The first connection unit 1 is provided with a plug rod. After the plug rod is inserted into the slot 7, it is electrically connected. The slot 7 is connected to the channel 11, and the channel 11 is connected to the outside.

[0025] The isolation sealing part one includes an isolation sealing section two 5 disposed at the end of the contact part one 4; the isolation sealing section two 5 is used to contact the isolation sealing section three 12 before the contact part one 4 and the contact part two 8 come into contact to form a movable isolation sealing structure.

[0026] The first isolation sealing part further includes an isolation sealing section 3 that wraps around the first contact part 4. The first contact end 13 of the first contact part 4 is disposed between the first isolation sealing section 3 and the second isolation sealing section 5, and the first contact end 13 protrudes from the first isolation sealing part. The second isolation sealing part includes a third isolation sealing section 12 and a fourth isolation sealing section 19. The second contact end 9 of the second contact part 8 is disposed between the third isolation sealing section 12 and the fourth isolation sealing section 19, and the second contact end 9 protrudes from the second isolation sealing part. When the first contact end 13 contacts the second contact end 9, the first isolation sealing section 3 and the second isolation sealing section 5 respectively contact the third isolation sealing section 12 and the fourth isolation sealing section 19 to form an isolation seal. It can be understood that the second isolation sealing section 5 is provided on the first isolation sealing section 3. The second isolation sealing section 5 has a certain length, so that when the second isolation sealing section 5 enters the slot 7, water in the slot 7 can be pushed out, thereby ensuring that the surrounding environment is waterless when the first contact part 4 and the second contact part 8 are in contact.

[0027] In this embodiment, the second isolation sealing section 5 and the third isolation sealing section 12 make initial contact and deform upon contact, gradually pushing the water on the surfaces of the second isolation sealing section 5 and the third isolation sealing section 12 downwards. Figure 1 As shown in the direction, when the rod is pushed out, a relatively dry contact surface is formed on the surfaces of contact part 1 4 and contact part 2 8. After contact part 1 4 and contact part 2 8 come into contact, the isolation sealing section 2 5 and the isolation sealing section 3 12 are completely squeezed and sealed, and the contact part 1 4 and contact part 2 8 are wrapped in it, so that water from the outside cannot come into contact with contact part 1 4 and contact part 2 8 through the contact position of isolation sealing section 2 5 and isolation sealing section 3 12. This makes contact part 1 4 and contact part 2 8 in a sealed environment isolated from the outside. As the rod is inserted, the water in the slot 7 can be pushed out from the channel, ensuring the insertion and removal pressure, so that the insertion and removal action can be carried out smoothly.

[0028] The isolation sealing section two 5 is used to form a movable isolation sealing structure with the isolation sealing section three 12 before the contact section one 4 and the contact section two 8 are contacted, and to discharge the liquid in the slot 7 from the channel 11 before the contact section one 4 and the contact section two 8 are contacted. It can be understood that when the isolation sealing section two is contacted with the isolation sealing section three 12, the first contact end 13 wrapped by the isolation sealing section two and the isolation sealing section three 12 is always in the isolation sealing structure, and with the continuous advancing, the isolation sealing structure moves from the initial end of the slot 7 to the position where the contact section two 8 is located, and finally the isolation sealing structure wraps the first contact end 13 which is isolated from water and contacts the contact section two 8 to form the final isolation, at this time, the isolation sealing structure moves to the end position, and the first contact end 13 is completely wrapped by the contact section two 8 and is isolated from the outside water.

[0029] The isolation sealing section one 3 wraps the contact section one 4 outside, the first contact end 13 of the contact section one 4 is exposed to the isolation sealing section one 3 and contacts the contact section two 8, and the other parts of the contact section one 4 (except the first contact end 13) are wrapped in the isolation sealing section one 3, and the other end of the contact section one 4 is encapsulated in the connection unit one 1 and connected with the circuit in the connection unit one 1. The encapsulation in the embodiment is physical encapsulation, that is, the encapsulation is filled with sealing glue around the circuit structure, which can ensure the sealing of the entire connection unit, so that the circuit structure and electronic elements inside are in a sealed environment, and there is no gap around the circuit structure and electronic elements, so that the electronic elements will not be deformed and eventually fail due to excessive water pressure when in deep sea water. The other end of the contact section one 4 is connected with the first encapsulation wire 6, and the outside of the first encapsulation wire 6 is provided with an insulating rubber, so as to ensure that the internal wire will not contact water.

[0030] The diameter of the isolation sealing section one 3 is greater than the diameter of the slot 7, the isolation sealing section three 12 is arranged in the slot 7, and the surfaces of the isolation sealing section one 3 and the isolation sealing section three 12 in contact are made of insulating soft material. Through extrusion, a tightly fitted structure can be formed between the isolation sealing section one 3 and the isolation sealing section three 12, so as to enhance the isolation sealing effect.

[0031] The contact section two 8 includes a second contact end 9, the second contact end 9 is exposed to the surface of the slot 7 and contacts the contact section one 4, the other positions of the contact section two 8 are wrapped in the connection unit two 2 and are in encapsulation, and the other end of the contact section two 8 is encapsulated in the connection unit two 2 and is connected with the circuit in the connection unit two 2.

[0032] The second connection unit 2 is equipped with a control unit 14, which is used to control the energization of the first contact part 4 and the second contact part 8 after they come into contact. The control unit 14 includes voltage-controlled, magnetically controlled, or electronic components. Taking a Hall element as an example, the control unit 14 is described below. Figure 5 As shown, a magnet 17 is provided on the first connection unit 1, and a sensor 18 is provided on the second connection unit 2. When the first connection unit 1 is inserted into the second connection unit 2, the magnet 17 gradually approaches the sensor 18, which triggers the Hall element inside the second connection unit 2, making the first contact 4 and the second contact 8 energized and connected. That is, when the first connection unit 1 and the second connection unit 2 are not inserted, the first contact 4 and the second contact 8 are in an open circuit and non-conductive state.

[0033] The control unit 14 is encapsulated within the connecting unit 2. The control unit 14 is encapsulated with a solid body to ensure the reliability of the entire control unit 14. The control unit 14 is isolated from the channel 11, that is, the control unit 14 and the channel 11 are not connected to each other, thus ensuring that water flowing in from the channel 11 cannot enter the control unit 14, causing the control unit 14 to fail when it comes into contact with water.

[0034] Connection unit 1 and connection unit 2 can be directly inserted and connected, such as a common socket plug. When the isolation sealing parts on connection unit 1 and connection unit 2 are inserted, a large frictional force is generated, which can ensure a stable connection during insertion. When pulling out, a large force is also required to overcome the frictional resistance. Therefore, this embodiment adds an unlocking structure to connection unit 1 and connection unit 2. The unlocking structure is used to provide auxiliary power when connecting / separating connection unit 1 and connection unit 2.

[0035] The unlocking structure mainly includes an unlocking gear 15 set on the connecting unit 1 and an unlocking rack 16 on the outer wall of the connecting unit 2. The unlocking gear 15 meshes with the unlocking rack 16. When inserted, the unlocking gear 15 rotates until it is inserted to the final position. When it is necessary to pull out the connecting unit 1, if it is difficult to pull it out directly, the rotating rod connected to the unlocking gear 15 can be manually rotated. By rotating the rod, the unlocking gear 15 is driven to rotate, thereby ensuring relative movement between the connecting unit 1 and the connecting unit 2, so that the connecting unit 1 is withdrawn from the connecting unit 2.

[0036] Those skilled in the art should recognize that the above embodiments are merely illustrative of the present invention and are not intended to limit the present invention. Any appropriate changes and modifications made to the above embodiments within the essential spirit and scope of the present invention fall within the scope of protection claimed by the present invention.
