Description

Technical Field

[0001] This invention relates to the field of plug-in interface technology, specifically to a plug-in interface for grid-connected power supply, load, and energy storage. Background Technology

[0002] In a grid-connected power supply, grid, load and energy storage system, the core function of the existing plug-in interface is to enable rapid connection and safe isolation between the power source, grid, load and energy storage device. Existing plug-in interfaces exhibit significant defects in practical applications. Their sealing performance is limited by static compression mechanisms, and single-material sealing rings are prone to permanent deformation or cracking under outdoor temperature variations or frequent plugging and unplugging, leading to sealing failure. Especially in humid, high-salt-spray, or dusty environments, the infiltration of moisture and impurities may cause electrochemical corrosion or a decline in insulation performance. At the same time, there is a lack of efficient linkage design: users need to operate the sealing and snap-fit ​​components in steps when plugging and unplugging, which is not only inefficient but also prone to incomplete sealing or loosening of the connection due to omission of steps. These shortcomings affect the long-term reliability and safety of the interface. To address these issues, we propose a source-grid-load-storage grid-connected plug-in interface. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide a source-grid-load-storage grid-connected plug-in interface that can realize dynamic sealing compensation and single-step operation functions through mechanical linkage, which can effectively solve the problems in the background technology.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a source-grid-load-storage grid-connected plug-in interface, including a first insulating sleeve and a connecting component; First insulating sleeve: A conductive head is fixed inside. A connecting cable is fixed at the left end inside the first insulating sleeve. The connecting cable is connected to the conductive head. Evenly distributed actuating components are installed inside the first insulating sleeve. A squeezing component is installed inside the first insulating sleeve. The squeezing component is connected to all the actuating components. A snap-fit ​​component and a pulling component are installed at the right end of the circumferential surface of the first insulating sleeve. The connecting component includes a second insulating sleeve, a conductive bracket, and a conductive cable. The second insulating sleeve corresponds to the first insulating sleeve. A conductive bracket is fixed inside the second insulating sleeve, and the conductive bracket corresponds to the conductive head. A conductive cable is fixed at the right end inside the second insulating sleeve, and the conductive cable is connected to the conductive bracket. A sealing component is installed between the first and second insulating sleeves, and the sealing component is connected to all the actuating components. The conductive bracket is connected to the conductive head.

[0005] Furthermore, the sealing assembly includes a first sealing ring and a first annular groove. An annular groove is provided at the right end of the first insulating sleeve, and the first sealing ring is slidably connected inside the annular groove. The first annular groove is provided at the left end of the second insulating sleeve. The first sealing ring and the first annular groove correspond to each other. By setting the sealing assembly, the gap between the first insulating sleeve and the second insulating sleeve is initially sealed.

[0006] Furthermore, the actuating assembly includes a strip-shaped opening, a rotating shaft, a gear ring, and toothed plates. The first insulating sleeve has evenly distributed strip-shaped openings inside. A rotating shaft is rotatably connected inside the strip-shaped openings. A gear ring is fixed on the circumferential surface of the rotating shaft. Two parallel toothed plates are slidably connected inside the strip-shaped openings. Both toothed plates mesh with the gear ring. All toothed plates adjacent to the first sealing ring are fixed inside the first sealing ring. By setting the actuating assembly, the first sealing ring will be moved under the action of the actuating assembly after the second sealing ring is inserted into the second annular groove.

[0007] Furthermore, the extrusion assembly includes a second sealing ring, an extrusion ring, and a first spring. An annular guide groove is formed inside the first insulating sleeve, and the extrusion ring is slidably connected inside the annular guide groove. A second annular groove is formed at the right end of the first insulating sleeve, and a second sealing ring is slidably connected inside the second annular groove. The second sealing ring is fixed to the right end of the extrusion ring. The left end of the extrusion ring is fixed with evenly distributed first springs. All the first springs are fixed inside the annular guide groove. All the toothed plates adjacent to the extrusion ring are fixed on the circumferential surface of the extrusion ring. The gap between the first insulating sleeve and the second insulating sleeve is further sealed by setting the second sealing ring.

[0008] Furthermore, the snap-fit ​​assembly includes a connecting ring, a snap post, a limiting plate, a second spring, and a snap groove. The connecting ring is fixed to the right end of the circumferential surface of the first insulating sleeve. An annular cavity is formed inside the connecting ring, and evenly distributed sliding holes are formed inside the connecting ring. A snap post is slidably connected inside the sliding holes. A limiting plate is fixed to the end face of the snap post inside the annular cavity. A second spring is sleeved on the circumferential surface of the snap post. One end of the second spring is fixed to the end face of the limiting plate, and the other end of the second spring is fixed inside the annular cavity. Evenly distributed snap grooves are formed on the circumferential surface of the second insulating sleeve. The snap grooves cooperate with the snap post, and the first insulating sleeve and the second insulating sleeve are connected by setting up the snap-fit ​​assembly.

[0009] Furthermore, the pulling assembly includes a slip ring and pull ropes. The connecting ring has evenly distributed mounting holes on its circumferential surface. Pull ropes are slidably connected inside the mounting holes. All pull ropes are fixed to the end faces of all the limiting discs. The connecting ring also has a slip ring slidably connected to its circumferential surface, and all pull ropes are fixed to the end faces of the slip rings. By setting up the pulling assembly, the user can pull the slip rings to move all the pull ropes during disassembly, thereby moving all the limiting discs. In this way, all the locking posts can be separated from all the locking slots, thus separating the first insulating sleeve and the second insulating sleeve.

[0010] Furthermore, the right end of the first insulating sleeve is provided with uniformly distributed limiting grooves, and the left end of the second insulating sleeve is fixed with uniformly distributed limiting heads. The limiting heads and limiting grooves correspond to each other. By setting the limiting heads and limiting grooves, the stability of the first insulating sleeve and the second insulating sleeve after connection is improved.

[0011] Furthermore, an annular fixing groove is formed on the circumferential surface of the slip ring, and an anti-slip ring is fixed inside the annular fixing groove. The anti-slip ring has evenly distributed anti-slip grooves on its circumferential surface. The anti-slip ring facilitates the user's movement by pulling the slip ring.

[0012] Furthermore, a fixing ring is fixed to the right end of the circumferential surface of the second insulating sleeve, and the right end of the fixing ring is provided with evenly distributed fixing holes. The fixing ring and fixing holes facilitate the fixing of the second insulating sleeve.

[0013] Furthermore, the connecting ring has evenly distributed strip-shaped guide grooves on its circumferential surface. Slider blocks are slidably connected inside the strip-shaped guide grooves, and all sliders are fixed inside the slip ring. The range of movement of the slip ring is limited by setting sliders and strip-shaped guide grooves.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: the plug-in interface for grid-connected load storage has the following advantages: 1. Through the linkage design of the extrusion component and the actuation component, the second sealing ring expands outward under the action of the first spring when it is inserted, and synchronously drives the toothed plate to drive the first sealing ring to slide into the first annular groove of the second insulating sleeve, forming a double sealing barrier; this dynamic compensation mechanism can automatically adapt to the wear of the seal caused by temperature difference deformation and frequent insertion and removal, effectively resist the penetration of moisture and impurities in humid, salt spray or sandy environments, and significantly enhance the long-term sealing reliability. 2. The snap-fit ​​assembly and the sealing assembly achieve functional linkage through the meshing transmission of the gear ring and the toothed plate; when the user inserts the first insulating sleeve, the snap-fit ​​post is automatically snapped into the slot by the push of the second spring, and at the same time the compression ring pushes the toothed plate to trigger the displacement of the sealing ring; during disassembly, only a single step is needed to pull the slip ring to release the snap-fit ​​and seal lock simultaneously through the pull rope; this design simplifies the multi-step operation into a single action, greatly improving efficiency and avoiding the risk of human error.

[0018] Please see Figure 1-5 This embodiment provides a technical solution: a source-grid-load-storage grid-connected plug-in interface, including a first insulating sleeve 1 and a connecting component 2; First insulating sleeve 1: A conductive head 11 is fixed inside. A connecting cable 12 is fixed to the left end inside the first insulating sleeve 1, and the connecting cable 12 is connected to the conductive head 11. Evenly distributed actuating components 4 are installed inside the first insulating sleeve 1.

A gear ring 43 is fixed on the circumferential surface of the rotating shaft 42. Two parallel gear rings are slidably connected inside the strip-shaped openings 41. The toothed plates 44 are both meshed with the gear ring 43. All the toothed plates 44 adjacent to the first sealing ring 31 are fixed inside the first sealing ring 31. The extrusion assembly 5 includes a second sealing ring 51, an extrusion ring 52, and a first spring 53. An annular guide groove is provided inside the first insulating sleeve 1, and the extrusion ring 52 is slidably connected inside the annular guide groove. A second annular groove is provided at the right end of the first insulating sleeve 1, and the second sealing ring 51 is slidably connected inside the second annular groove.

The left end of the extrusion ring 52 is fixed with evenly distributed first springs 53, and all the first springs 53 are fixed inside the annular guide groove. All the toothed plates 44 adjacent to the extrusion ring 52 are fixed to the extrusion ring 53. On the circumferential surface of ring 52, the snap-fit ​​assembly 6 includes a connecting ring 61, a snap-fit ​​post 62, a limiting disc 63, a second spring 64, and a snap-fit ​​groove 65.

One end of the second spring 64 is fixed to the end face of the limiting disc 63, and the other end of the second spring 64 is fixed inside the annular cavity.

The pulling assembly 7 includes... The connecting ring 61 has evenly distributed mounting holes on its circumferential surface, and the pull ropes 72 are slidably connected inside the mounting holes. All the pull ropes 72 are fixed to the end faces of all the limiting discs 63. The connecting ring 61 is slidably connected to the circumferential surface of the connecting ring 61, and all the pull ropes 72 are fixed to the end faces of the slip rings 71. By setting up the pulling component 7, the user can pull the slip rings 71 to move all the pull ropes 72 during disassembly, thereby moving all the limiting discs 63. In this way, all the locking posts 62 can be separated from all the locking slots 65, and the first insulating sleeve 1 and the second insulating sleeve 21 can be separated. The first insulating sleeve 1 and the second insulating sleeve 21 are connected by setting up the locking component 6.The gap between the first insulating sleeve 1 and the second insulating sleeve 21 is further sealed by setting a second sealing ring 51. The actuating component 4 causes the first sealing ring 31 to move under the action of the actuating component 4 after the second sealing ring 51 is inserted into the second annular groove. Connection component 2 includes a second insulating sleeve 21, a conductive bracket 22, and a conductive cable 23. The second insulating sleeve 21 corresponds to the first insulating sleeve 1. The conductive bracket 22 is fixed inside the second insulating sleeve 21 and corresponds to the conductive head 11. The conductive cable 23 is fixed at the right end inside the second insulating sleeve 21 and is connected to the conductive bracket 22. A sealing component 3 is installed between the first insulating sleeve 1 and the second insulating sleeve 21. The sealing component 3 is connected to all the actuating components 4. The sealing component 3 includes a first sealing ring 31 and a first annular groove 32. An annular groove is opened at the right end of the first insulating sleeve 1, and the first sealing ring 31 is slidably connected inside the annular groove. The first annular groove 32 is opened at the left end of the second insulating sleeve 21. The first sealing ring 31 and the first annular groove 32 correspond to each other. The sealing component 3 is used to initially seal the gap between the first insulating sleeve 1 and the second insulating sleeve 21. The conductive bracket 22 is connected to the conductive head 11.

[0019] Wherein: the right end of the first insulating sleeve 1 is provided with uniformly distributed limiting grooves 9, and the left end of the second insulating sleeve 2 is fixed with uniformly distributed limiting heads 8. The limiting heads 8 and the limiting grooves 9 correspond to each other. By setting the limiting heads 8 and the limiting grooves 9, the stability of the first insulating sleeve 1 and the second insulating sleeve 21 after connection is improved.

[0020] Among them, an annular fixing groove is provided on the circumferential surface of the slip ring 71, and an anti-slip ring 10 is fixed inside the annular fixing groove. The anti-slip ring 10 has evenly distributed anti-slip grooves on its circumferential surface. The anti-slip ring 10 facilitates the user to pull the slip ring 71 to move it.

[0021] Wherein: a fixing ring 13 is fixed to the right end of the circumferential surface of the second insulating sleeve 21, and a fixing hole 14 is evenly distributed on the right end of the fixing ring 13. The fixing ring 13 and the fixing hole 14 facilitate the fixing of the second insulating sleeve 21.

[0022] Wherein: the circumferential surface of the connecting ring 61 is provided with uniformly distributed strip guide grooves 15, and the inside of the strip guide grooves 15 is slidably connected to the sliders 16. All the sliders 16 are fixed inside the slip ring 71. The range of movement of the slip ring 71 is limited by setting the sliders 16 and the strip guide grooves 15.

[0023] The working principle of the source-grid-load-storage grid-connected plug-in interface provided by this invention is as follows: When connection is required, the user inserts the conductive head 11 of the first insulating sleeve 1 into the conductive seat 22 of the second insulating sleeve 21. At this time, the limiting head 8 at the left end of the second insulating sleeve 21 is embedded in the limiting groove 9 at the right end of the first insulating sleeve 1 to ensure axial alignment. During the insertion process, the second insulating sleeve 21 pushes the second sealing ring 51 to the left, and the second sealing ring 51 drives the compression ring 52 to compress the first spring 53. Simultaneously, the toothed plate 44 fixed on the circumferential surface of the compression ring 52 moves accordingly, driving the gear ring 43 to rotate, which in turn drives the other toothed plate 44 connected to the first sealing ring 31 to move to the right, so that the first sealing ring 31 slides from the annular groove into the first annular groove 32 of the second insulating sleeve 21, completing the first seal. When inserted into place, the snap-fit ​​assembly 6 is automatically triggered: the second insulating sleeve 21 squeezes the snap-fit ​​post 62, and the snap-fit ​​post 62 drives the limiting plate 63 to compress the second spring 64 and retract into the annular cavity of the connecting ring 61; when the snap-fit ​​post 62 is aligned with the snap-fit ​​groove 65, the second spring 64 pushes the limiting plate 63 to reset, so that the snap-fit ​​post 62 is snapped into the snap-fit ​​groove 65 to complete the mechanical locking. At this time, the second sealing ring 51 will form the second dynamic seal. The double sealing structure effectively resists environmental erosion. During disassembly, the user pulls the anti-slip ring 10 outward to drive the slip ring 71. The slip ring 71, through the pull rope 72, simultaneously pulls all the limit discs 63 to compress the second spring 64, causing the locking post 62 to disengage from the locking groove 65. When the first insulating sleeve 1 is pulled out in the opposite direction, the first spring 53 pushes the compression ring 52 to reset, and the gear ring 43 rotates in the opposite direction to drive the first sealing ring 31 to retract into the annular sliding groove, achieving non-destructive separation of the sealing structure. The entire process achieves synchronous action of sealing and locking through mechanical linkage, improving operational efficiency and reliability.
