Description

Technical Field

[0001] The present invention relates to the technical field of waterborne power connectors, and in particular to a new energy power waterproof connector for ships. Background Art

[0002] Power connectors are indispensable components in electrical and electronic equipment. They are mainly responsible for the circuit connection between cables and cables, and between cables and equipment. They play an outstanding role in electrical control systems and power supply applications. They can efficiently transmit large currents and voltages to ensure the stable operation of electrical equipment. The power connector usually consists of two parts: a fixed end connector and a free end connector. The fixed end connector is a passive connection part installed on the panel and the base, and the free end electrical connector is an active connection part that cooperates with the fixed end electrical connector. Compared with ordinary power connectors, ship power connectors need to use special sealing materials and designs to ensure safe and reliable operation on water. Usually, this type of connector is designed with multiple waterproof channels. Even if moisture passes through the shell, it is difficult to contact the connector through the waterproof channels. Waterproof sealing tape is used to isolate the shell from moisture, thereby achieving insulation and sealing protection between the electrical component interfaces. However, in actual use, excessive sealing or the use of inappropriate materials can easily lead to the ineffective dissipation of heat, especially in severe weather. Most of the equipment on board needs to operate continuously at high power, and the heat needs to be released through waterproof channels and waterproof sealing tapes. The heat dissipation system cannot dissipate the heat in time, which leads to overheating of the equipment. Therefore, there is a need for an electrical connector that can ensure good heat dissipation when the waterproof requirement is low and can perform emergency waterproofing when the waterproof requirement is high. Summary of the invention

Under the guidance of the first guide groove, the sliding seat moves in a spiral shape along the trajectory of the first guide groove with the ring as the axis. The sliding seat drives the gel storage chamber and the discharge pipe to rotate through the push rod, so that the discharge pipe rotates under the restriction of the heat sink.

[0014] In summary, due to the adoption of the above-mentioned technology, a new energy power waterproof connector for ships has the following beneficial effects: 1. Through the waterproof kit and push mechanism, when there is a low waterproof requirement, such as rainy and snowy weather, the protective shell can block the entry of moisture, and at the same time, the heat generated when the equipment is running at high power can be effectively discharged through the heat dissipation holes of the heat sink, thereby avoiding overheating caused by poor heat release; when encountering bad weather, when the free-end connector and the fixed-end connector are likely to be soaked in water or impacted by water waves, the thermal conductive gel is sprayed out from the gel storage cavity through the discharge pipe and injected into the heat sink to fill the joint between the free-end connector and the fixed-end connector, and a thermal conductive gel layer is formed under the restriction of the heat sink to isolate moisture, and at the same time, an almost seamless heat conduction path is formed between the free-end connector and the fixed-end connector, reducing thermal resistance, improving heat conduction efficiency, and cooperating with the heat sink to quickly conduct heat away, ensuring that the equipment still maintains normal temperature under high-load operation; 2. Through the steering mechanism, when the push rod moves under the pull of the spring elastic deformation recovery, the push rod pulls the sliding seat and the first guide shaft to move and makes the first guide shaft abut against the first guide groove. Under the guidance of the first guide groove, the sliding seat moves in a spiral shape along the trajectory of the first guide groove with the free end connector as the axis. The sliding seat drives the gel storage chamber and the discharge pipe to rotate through the push rod. Since the heat sink is rotatable, the discharge pipe can rotate under the restriction of the heat sink. At this time, the heat-conducting gel is ejected from the discharge pipe as the piston pushes. The discharge pipe injects the heat-conducting gel into the heat sink in a rotating state, forming a heat-conducting gel ring with uniform thickness and fitting the seams of the free end connector and the fixed end connector. 3. Through the set limit mechanism and water tank, when the waterproof requirement is low, such as in rainy and snowy weather, rainwater enters the water tank and is discharged through the drainage hole. The gravity is not enough to pull the slide bar through the connecting rod to release the restriction on the push rod, and the release of the thermal conductive gel will not be triggered; when the waterproof requirement is high, such as when the rainfall is too heavy to be quickly discharged from the water tank through the drainage hole, or when it is hit by waves and a large amount of water pours into the water tank, the water tank drops rapidly under the action of gravity and pulls the slide bar through the connecting rod to release the restriction on the push rod, triggering the release of the thermal conductive gel for emergency sealing.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technology in the embodiments of the present invention, a new energy power waterproof connector for ships. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] In order to solve the problem that excessive sealing or the use of inappropriate materials can easily lead to the ineffective heat dissipation, especially in bad weather, most of the equipment on board needs to operate at high power continuously, and the heat needs to be released through waterproof channels and waterproof sealing tapes. The heat dissipation system cannot dissipate the heat in time, which leads to the problem of equipment overheating. The present invention proposes a ship new energy power waterproof connector, such as Figure 1 - Fig.15 As shown: The fixed end connector 20 includes a fixed end connector 20 installed vertically with the port facing downward and a free end connector 10 installed on the fixed end connector 20. Compared with horizontal installation, the advantage of vertical installation is that the water accumulated in the fixed end connector 20 can be discharged more easily by using gravity, thereby keeping the fixed end connector 20 dry. The fixed end connector 20 is provided with a waterproof kit 30 for waterproofing. Figure 1 , Figure 2 and Figure 5 As shown, the waterproof kit 30 includes a heat sink 32 and a protective shell 33 rotatably arranged on the surface of the fixed end connector 20, the inner wall of the protective shell 33 is provided with a thread, and the surface of the free end connector 10 is provided with a thread groove that meshes with the drainage hole 34, as shown in FIG. Figure 4 As shown, after the free-end connector 10 is connected to the fixed-end connector 20, the protective shell 33 is rotated to connect the free-end connector 10 for reinforcement, and a heat dissipation hole is opened on the surface of the heat dissipation member 32 and is located at the joint between the free-end connector 10 and the fixed-end connector 20; The waterproof kit 30 also includes a rotating member 31 rotatably arranged on the fixed end connector 20, the heat sink 32 is rotatably connected to the rotating member 31 and the protective shell 33 is rotatably connected to the heat sink 32. After the free end connector 10 is connected to the fixed end connector 20, the protective shell 33 is sleeved on the surface of the free end connector 10, and then the protective shell 33 is rotated to rotate under the restriction of the heat sink 32 until the protective shell 33 is connected to the free end connector 10 through threads and cannot rotate. At this time, the heat sink 32 can rotate between the rotating member 31 and the protective shell 33. When the waterproof requirement is low, such as in rainy and snowy weather, the protective shell 33 can block the entry of moisture. At the same time, the heat generated by the high-power operation of the device can be effectively discharged through the heat dissipation holes of the heat sink 32, thereby avoiding overheating caused by poor heat release; At the same time, if Figure 2and Figure 5 As shown, a number of drainage holes 34 are equidistantly arranged on the surface of the protective shell 33. The top of the drainage hole 34 is opened on the inner wall of the protective shell 33 and the bottom is through-set. The hole wall is arranged to be inclined to prevent moisture from directly pouring in. Through this design, water molecules entering through the heat dissipation holes of the heat dissipation element 32 can be discharged from the protective shell 33 through the drainage holes 34 after condensation to avoid moisture accumulation. While preventing rainwater from entering the protective shell 33 through the drainage holes 34, water pouring into the drainage holes 34 from bottom to top can also be blocked by the inclined inner wall, and moisture cannot easily enter.

[0019] When encountering bad weather, the free end connector 10 and the fixed end connector 20 may be soaked in water or impacted by waves. When the waterproof requirement is increased, the push mechanism 40 can be used to seal. Figure 3 , Figure 6-Figure 8 As shown, a push mechanism 40 for emergency sealing is installed on the heat sink 32, and the push mechanism 40 includes a discharge pipe 44 penetrating the heat sink 32 and a gel storage chamber 41 connected to the discharge pipe 44, a movable piston 42 is arranged inside the gel storage chamber 41, and heat-conducting gel is stored between the piston 42 and the discharge pipe 44; The pushing mechanism 40 further includes a push rod 43 that passes through the middle of the gel storage chamber 41 and is connected to the piston 42, and an inlet hole 411 that is opened on the gel storage chamber 41. The thermal conductive gel is injected into the gel storage chamber 41 through the inlet hole 411. The gel storage chamber 41 is installed through the installation hole 331 and the positioning frame 332 provided on the protective shell 33. Figure 5 and Figure 6 As shown, by pulling the push rod 43, the piston 42 moves to the end of the gel storage chamber 41 away from the discharge pipe 44, and the feed hole 411 is opened to inject the thermal conductive gel. After the injection is completed, the gel storage chamber 41 is placed on the mounting hole 331, and then the positioning frame 332 is connected to the mounting hole 331 with bolts to fix the gel storage chamber 41. The installation of the gel storage chamber 41 is completed; When there is a risk of water immersion in the free-end connector 10 and the fixed-end connector 20, the push rod 43 is pushed so that the push rod 43 drives the piston 42 to move inside the gel storage chamber 41 to shorten the distance between the push rod 43 and the discharge pipe 44. As the space in the gel storage chamber 41 is compressed, the thermally conductive gel is ejected from the gel storage chamber 41 through the discharge pipe 44 and injected into the heat sink 32 to fill the joint between the free-end connector 10 and the fixed-end connector 20, and a thermally conductive gel layer is formed under the restriction of the heat sink 32 to isolate moisture. At the same time, an almost seamless heat conduction path is formed between the free-end connector 10 and the fixed-end connector 20, reducing thermal resistance and improving heat conduction efficiency. The heat sink 32 is used to quickly conduct heat away to ensure that the equipment maintains normal temperature under high-load operation. It should be noted that the thermal conductivity of the hydrophobic thermally conductive gel may be affected after contact with water, so hydrophilic thermally conductive gel is preferably used.

[0020] In order to enable the push rod 43 to move by itself, a mounting cavity 431 is provided in the middle of the push rod 43, and a positioning mechanism 50 for controlling the movement of the push rod 43 is provided in the mounting cavity 431. Figure 7 and Figure 8 As shown; The positioning mechanism 50 includes a clamping groove 51 disposed in the middle of the gel storage cavity 41 and a positioning block 52 embedded in the clamping groove 51. The positioning block 52 is provided with a protrusion connected to the clamping groove 51. A straight groove for the protrusion to penetrate is provided on the surface of the installation cavity 431. When the push rod 43 moves, the straight groove provided on the installation cavity 431 moves in contact with the surface of the protrusion. The other end of the spring 53 is connected to the inner wall of the installation cavity 431, and one end of the spring 53 is connected to the positioning block 52. Through this design, the spring 53 is arranged inside the installation cavity 431, and the installation cavity 431 can protect the spring 53, thereby achieving the purpose of slowing down the rust speed of the spring 53; By pulling the push rod 43, the push rod 43 pulls the piston 42 to move inside the gel storage chamber 41 under the restriction of the clamping groove 51 and the positioning block 52. As the distance between the positioning block 52 and the push rod 43 increases, the spring 53 is pulled and elastically deformed. At this time, if the push rod 43 is released, the push rod 43 can push the piston 42 to move by itself under the pulling of the spring 53 to restore its elastic deformation, so that the thermal conductive gel in the gel storage chamber 41 is ejected.

[0021] Furthermore, in order to make the thermal conductive gel evenly cover the joint between the free end connector 10 and the fixed end connector 20 to form an effective waterproof layer, while avoiding excessive thermal conductive gel from hindering the heat dissipation, as shown in FIG. Figure 4 , Fig. 9 and Fig.10As shown, the end of the push rod 43 is connected to a steering mechanism 60, which includes a sliding seat 61 arranged on the end of the push rod 43 and a collar 63 installed on the surface of the free end connector 10, a first guide groove 64 is provided on the collar 63, and a first guide shaft 62 that cooperates with the first guide groove 64 is provided on the sliding seat 61; When the push rod 43 moves under the pull of the elastic deformation recovery of the spring 53, the push rod 43 pulls the sliding seat 61 and the first guide shaft 62 to move and make the first guide shaft 62 abut against the first guide groove 64. Under the guidance of the first guide groove 64, the sliding seat 61 moves in a spiral shape along the trajectory of the first guide groove 64 with the free end connector 10 as the axis. The sliding seat 61 drives the gel storage chamber 41 and the discharge pipe 44 to rotate through the push rod 43. Since the heat sink 32 is rotatable, the discharge pipe 44 can rotate under the restriction of the heat sink 32. At this time, as the piston 42 pushes, the thermal conductive gel is ejected from the discharge pipe 44. The discharge pipe 44 injects the thermal conductive gel into the heat sink 32 in a rotating state, forming a thermal conductive gel ring with uniform thickness and fitting the seams with the free end connector 10 and the fixed end connector 20. Preferably, two pushing mechanisms 40 are provided and are symmetrical, and both push rods 43 are provided with a sliding seat 61 and a first guide shaft 62, and two first guide grooves 64 are provided on the ring 63. The number of circles of the first guide groove 64 from the starting point to the end point is one circle, and the distance between the starting point and the end point of the first guide groove 64 is the same as the maximum distance that the piston 42 can move inside the gel storage chamber 41. After the piston 42 completes pushing, the first guide shaft 62 moves to the end point of the first guide groove 64. During this process, the two discharge pipes 44 rotate one circle respectively and inject the thermal conductive gel. Through two injections, the thickness of the thermal conductive gel ring is ensured to be uniform and fit.

[0022] After the push rod 43 is pulled to the specified position and the first guide shaft 62 reaches the starting point of the first guide groove 64, the position of the push rod 43 needs to be limited, and the limit can be automatically released when high waterproof requirements are met. The position of the push rod 43 is locked by the limit mechanism 70. Figure 7 , Figure 8 , Figure 11-Figure 14 As shown, the limiting mechanism 70 includes a mounting seat 75 rotatably disposed inside the sliding seat 61, a rotating shaft 71 rotatably disposed in the middle of the mounting seat 75 and penetrating the mounting cavity 431 and the middle of the positioning block 52, and a limiting groove 74 opened in the positioning block 52; The limiting groove 74 includes a straight groove portion and an arc groove portion that are interconnected. A limiting block 72 that cooperates with the limiting groove 74 is provided at the end of the rotating shaft 71. After the push rod 43 is pulled to the specified position, the rotating shaft 71 drives the limiting block 72 to insert into the straight groove portion of the limiting groove 74. At this time, the rotating shaft 71 is rotated again to make the rotating shaft 71 drive the limiting block 72 to rotate, and the limiting block 72 enters the arc groove portion. Under the restriction of the arc groove portion, the limiting block 72 cannot move. When the limiting block 72 is restricted, the push rod 43 cannot move, thereby achieving the purpose of restricting the push rod 43 so that it cannot reset itself. At the same time, the limiting mechanism 70 also includes a spiral second guide groove 73 provided on the surface of the rotating shaft 71 and a sliding rod 76 nested on the mounting seat 75. The sliding rod 76 is provided with a second guide shaft 77 that cooperates with the second guide groove 73. When it is necessary to release the restriction on the position of the push rod 43, the sliding rod 76 is pulled by external force to move the sliding rod 76 under the restriction of the second guide shaft 77, and the second guide shaft 77 is driven to abut against the second guide groove 73 during the movement. Under the push of the second guide shaft 77 and the guidance of the second guide groove 73, the rotating shaft 71 rotates in the middle of the mounting seat 75, so that the rotating shaft 71 can drive the limiting block 72 to rotate out of the arc groove portion of the limiting groove 74, and the restriction of the limiting groove 74 on the limiting block 72 is released; It should be noted that in the process of embedding the limit block 72 into the limit groove 74, it is necessary to manually pull the slide rod 76 first, so that the rotating shaft 71 drives the limit block 72 to rotate to an angle that can be inserted into the straight groove part of the limit groove 74. After the push rod 43 is pulled to the specified position, the slide rod 76 is pushed to reset, so that the slide rod 76 cooperates with the second guide shaft 77 to drive the rotating shaft 71 to rotate.

[0023] In order to control whether the slide bar 76 is pulled by an external force according to the waterproof requirements of the free end connector 10 and the fixed end connector 20, a connecting rod 81 is connected to the end of the slide bar 76, and a water tank 82 is connected to the connecting rod 81. The water tank 82 is annular and sleeved on the free end connector 10, and a plurality of drainage holes are opened at the bottom of the water tank 82; When the waterproof requirement is low, such as in rainy and snowy weather, rainwater enters the water tank 82 and is discharged through the drainage hole. The gravity is not enough to pull the sliding rod 76 through the connecting rod 81 to release the restriction on the push rod 43, and the release of the thermal conductive gel will not be triggered. In case of high waterproof requirements, such as when the rainfall is too heavy to be quickly discharged from the water tank 82 through the drainage holes, or when a large amount of water is splashed into the water tank 82 by waves, the water tank 82 drops rapidly under the action of gravity and pulls the sliding rod 76 through the connecting rod 81 to release the restriction of the push rod 43, triggering the release of the thermal conductive gel for emergency sealing; Compared with directly coating the thermal conductive gel on the free-end connector 10 and the fixed-end connector 20, the advantage of coating the thermal conductive gel when high waterproof requirements are required is that it can provide additional protection for the free-end connector 10 and the fixed-end connector 20 under harsh conditions, while avoiding the problem of aging, cracking or falling off of the thermal conductive gel applied in advance after long-term use, thereby affecting the sealing effect. Without shortening the service life of the thermal conductive gel, its stability and reliability in dealing with high waterproof requirements are increased. After the waterproof requirement is reduced, the staff can regularly remove the thermal conductive gel ring and add new thermal conductive gel to the gel storage cavity 41.

[0024] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes to a ship new energy power waterproof connector and its inventive concept according to the technology of the present invention, which should be covered within the protection scope of the present invention.
