Description

Technical Field

[0001] The present invention relates to the technical field of energy storage connectors, and more specifically, to a waterproof energy storage connector. Background Art

[0002] An energy storage connector is a special type of electrical connector used in energy storage systems (such as battery energy storage systems). These connectors are responsible for establishing a safe and reliable electrical connection between energy storage devices (such as battery packs) and power conversion systems (such as inverters or charge controllers).

[0003] In actual applications, especially for outdoor energy storage power stations, the energy storage connector needs to be waterproofed. Waterproof energy storage connectors play a crucial role in energy storage systems. They ensure the safe and reliable transmission of electrical energy between different components while resisting moisture erosion in the external environment. Existing energy storage connectors often increase the tightness by sleeving a rubber ring inside the docking tube to achieve waterproofing. However, this method is prone to damage during the insertion and extraction process, and there is also the problem of insufficient waterproofing. Because if the rubber ring is too thick, it is not easy to dock, and if it is too thin, the waterproof effect cannot be achieved, making it difficult to meet the usage requirements. Summary of the Invention

[0004] To solve the problems raised in the background art, the purpose of the present invention is to provide a waterproof energy storage connector. By setting a waterproof ring and a second annular airbag, when the docking sleeve is inserted, it cooperates with the trigger assembly and the arc-shaped groove, and then the extrusion assembly automatically extrudes the first annular airbag through the linkage mechanism, so that the gas is filled into the second annular airbag, pushing up the second rubber ring to fit and press tightly against the inner wall of the docking sleeve, which is beneficial to forming a multi-layer waterproof barrier, thereby achieving a reliable waterproof effect.

[0005] To achieve the above purpose, a waterproof energy storage connector of the present invention includes a mounting base and a plug base. One side of the mounting base is provided with a first conductive terminal, and the other side is provided with a second conductive terminal. A docking sleeve is arranged inside the plug base, and a third conductive terminal is arranged inside the docking sleeve.

[0006] Among them, an extrusion assembly is rotatably connected to the second conductive terminal. Two trigger assemblies are symmetrically arranged at one end of the extrusion assembly away from the mounting base. A first annular airbag is arranged at the other end of the extrusion assembly. A fixing sleeve is arranged on one side of the first annular airbag adjacent to the mounting base. The fixing sleeve is fixedly arranged on the mounting base. A plurality of annular grooves are formed on the fixing sleeve, and a waterproof ring is arranged inside the annular grooves. The waterproof ring is communicated with the first annular airbag.

[0007] On the side of the mounting base away from the first conductive terminal, a ferrule is further provided. A first annular clamping cavity is formed in the ferrule. The ferrule is symmetrically provided with limiting blocks. The docking sleeve is used for sleeving the fixing sleeve. A second annular clamping cavity adapted to the ferrule is also formed in the plug base. An extrusion ring adapted to the first annular clamping cavity is arranged in the second annular clamping cavity. A first rubber ring is arranged at the front end of the extrusion ring for tightly attaching to the inner wall of the first annular clamping cavity. A limiting groove adapted to the limiting block is also formed in the plug base for restricting the docking direction of the docking sleeve and the fixing sleeve in the plug base.

[0008] An activity cavity is formed in the mounting base. A clamping component is arranged in the activity cavity. A control component for controlling the clamping component is also arranged in the mounting base. A first clamping groove adapted to the clamping component is formed in the plug base. A clamping block adapted to the clamping component is arranged in the first clamping groove. The clamping component is clamped into the first clamping groove through the clamping block to prevent the plug base from falling off.

[0009] Arc-shaped grooves adapted to the triggering component are symmetrically formed in the docking sleeve for driving the extrusion component to extrude the first annular airbag during the docking process of the docking sleeve and the fixing sleeve. The first annular airbag is used for inflating the waterproof ring. The waterproof ring is used for tightly pressing against the inner wall of the docking sleeve.

[0010] As a further improvement of this technical solution, the extrusion component includes a rotating sleeve rotatably connected to the second conductive terminal. A rotating ring is fixed to one end of the rotating sleeve adjacent to the mounting base. A plurality of first wedge blocks are fixedly connected to the rotating ring. A second wedge block is arranged on the first wedge block. A guide rod is fixedly connected to the second wedge block. A plurality of guide grooves corresponding to the first wedge blocks are formed on the side of the fixing sleeve opposite to the rotating sleeve. The guide rod is slidably connected in the guide groove.

[0011] As a further improvement of this technical solution, both the first wedge block and the second wedge block are arc-shaped wedge structures, and the surface of the second wedge block in contact with the first annular airbag is adapted to the inner wall of the first annular airbag. The distance that the rotating ring extrudes the second wedge block to slide along the guide groove is adapted to the thickness of the first annular airbag.

[0012] As a further improvement of this technical solution, the outer wall of the first annular airbag is flush with the outer walls of the rotating sleeve and the fixing sleeve and is made of a hard material. One side of the first annular airbag is fixedly connected to the fixing sleeve. The gas discharged from the first annular airbag extruded by the second wedge block enters a plurality of the waterproof rings, which is adapted to the waterproof requirement that the waterproof rings are jacked up and tightly press against the inner wall of the docking sleeve.

[0013] Preferably, the waterproof ring includes a second rubber ring and a second annular airbag. The second annular airbag is fixedly connected in the annular slot, and the second rubber ring is fixedly connected to the outer wall of the outer ring of the second annular airbag. In the initial stage, both the second rubber ring and the second annular airbag are clamped into the annular slot.

[0014] As a further improvement of this technical solution, the trigger assembly includes a trigger box fixedly connected in the rotating sleeve. A trigger block is slidably connected in the trigger box. A first spring is arranged in the trigger box. One end of the first spring is fixedly connected to the bottom end of the trigger block located in the trigger box, and the other end is fixedly connected to the inner wall of the bottom end of the trigger box. Both the front and rear ends of the trigger block along the axial direction of the rotating sleeve are wedge-shaped structures, and the height of the trigger block is adapted to the depth of the arc-shaped groove.

[0015] Preferably, the length of the arc-shaped groove is adapted to the angle that the first wedge block needs to rotate when the gas discharged from the first annular airbag driven by the first wedge block through the trigger block drives the second wedge block to squeeze the first annular airbag, so that the first annular airbag can meet the requirement of jacking up the waterproof ring to abut against the inner wall of the docking sleeve.

[0016] As a further improvement of this technical solution, when the arc-shaped groove starts to contact the trigger block, the limiting block starts to contact the limiting groove;

[0017] And when the trigger block reaches the end of the arc-shaped groove, the limiting block completely enters the docking sleeve, and at this time, the engaging assembly is engaged with the engaging block in the first card slot.

[0018] Preferably, the engaging assembly includes a mounting rod fixedly connected in the movable cavity. A engaging rod is rotatably connected to the mounting rod. A torsion spring is arranged at the connection between the mounting rod and the engaging rod. One end of the torsion spring is fixedly connected to the mounting rod, and the other end is fixedly connected to the engaging rod;

[0019] The torsion spring always has a tendency to cause the engaging rod to rotate upward, and the engaging rod has a space for up and down rotation in the movable cavity and the first card slot. The end of the engaging rod away from the mounting rod extends to the outside of the movable cavity and forms a wedge-shaped engaging portion. The engaging portion of the movable cavity is adapted to the engaging block.

[0020] As a further improvement of the technical solution, the control component includes a control cylinder fixedly connected inside the mounting base. A limiting ring is slidably connected to the control cylinder, and the limiting ring is fixedly connected to the pressing rod. The pressing rod is slidably connected inside the control cylinder through the limiting ring. A second spring is arranged inside the control cylinder. One end of the second spring is fixedly connected to the bottom end of the limiting ring, and the other end is fixedly connected to the inner wall of the bottom end of the control cylinder. The pressing rod is arranged directly above the engaging rod, and the bottom end of the pressing rod can penetrate and slide through the control cylinder and the movable cavity to squeeze the engaging rod to rotate downward. The top end of the pressing rod extends to the outside of the mounting base to form a pressing part for manual pressing.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] 1. In this waterproof energy storage connector, when the docking sleeve is snapped into the fixed sleeve, the extrusion component is driven to work through the triggering component, squeezing the first annular airbag, and discharging the gas inside it into the second annular airbag, thereby pushing up the second rubber ring to fit and press tightly against the inner wall of the docking sleeve, forming multiple waterproof barriers. Secondly, by automatically inflating to push up the second rubber ring, during the process of the docking sleeve being snapped in, the second rubber ring slowly rises from the annular card slot to press tightly against the inner wall of the docking sleeve. This progressive contact method reduces the direct friction and wear with the inner wall of the docking sleeve, effectively improving the waterproof effect.

[0023] 2. In this waterproof energy storage connector, by utilizing the linkage between the triggering component and the engaging component, during the process of the docking sleeve being snapped in, through the interaction between the triggering block and the arc-shaped groove, the rotating sleeve is automatically driven to rotate, and then the waterproof ring is inflated and waterproofed through the extrusion component. At the same time, when the docking sleeve is completely snapped in, the engaging rod in the engaging component just snaps onto the engaging block in the first card slot, achieving automatic limiting. When disassembling, just press the pressing rod to release the engagement, which is convenient and fast.

[0024] 3. In this waterproof energy storage connector, the first rubber ring is arranged at the front end of the extrusion ring to be tightly attached to the inner wall of the first annular card cavity to form the first waterproof barrier. And the second rubber ring is pushed up by the inflation of the first annular airbag during the process of the docking sleeve being snapped in and fits and presses tightly against the inner wall of the docking sleeve to form the second waterproof barrier. This dual waterproof design greatly improves the waterproof performance of the energy storage connector. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0045] The problem that the rubber ring in the existing energy storage connector cannot meet the usage requirements of waterproofing and convenient installation and disassembly.

[0046] For this reason, the present invention provides a waterproof energy storage connector. Refer to Figure 1 and Figure 10 As shown, it includes a mounting base 1 and a plug base 4. One side of the mounting base 1 is provided with a first conductive terminal 2, and the other side is provided with a second conductive terminal 3. A docking sleeve 22 is arranged in the plug base 4, and a third conductive terminal 5 is arranged in the docking sleeve 22. Hold the plug base 4 and align the docking sleeve 22 with the second conductive terminal 3 so that it fits with the third conductive terminal 5 in the docking sleeve 22 to realize circuit connection.

[0047] Specifically, refer to Figure 2 and Figure 3 As shown, a pressing assembly 6 is rotatably connected to the second conductive terminal 3. Two trigger assemblies 7 are symmetrically arranged at one end of the pressing assembly 6 away from the mounting base 1. A first annular airbag 9 is arranged at the other end of the pressing assembly 6. A fixing sleeve 8 is arranged on the side of the first annular airbag 9 adjacent to the mounting base 1. The fixing sleeve 8 is fixed on the mounting base 1. A plurality of annular slots 11 are formed in the fixing sleeve 8, and a waterproof ring 10 is arranged in the annular slots 11. The waterproof ring 10 is communicated with the first annular airbag 9; and from Figure 8 and Figure 9It can be seen that the waterproof ring 10 includes a second rubber ring 101 and a second annular airbag 102. The second annular airbag 102 is fixedly connected in the annular slot 11, and the second rubber ring 101 is fixedly connected to the outer wall of the outer circle of the second annular airbag 102. In the initial stage, both the second rubber ring 101 and the second annular airbag 102 are clamped into the annular slot 11. A number of waterproof rings 10 are provided here to improve the waterproof effect. In this way, when the second annular airbag 102 is inflated and lifted, it further lifts the second rubber ring 101 to fit and press tightly against the inner wall of the docking sleeve 22, forming a number of waterproof barriers. Moreover, with this design, in the initial stage, when the second annular airbag 102 is not inflated by the first annular airbag 9, the second rubber ring 101 and the second annular airbag 102 can be clamped into the annular slot 11 together, which is convenient for the docking sleeve 22 to be inserted. And according to the linkage effect described below, when the docking sleeve 22 is inserted into the fixed sleeve 8, it automatically squeezes the first annular airbag 9 to inflate the second annular airbag 102, making it press tightly against the docking sleeve 22, thus better achieving the waterproof effect and being convenient for disassembly.

[0048] Among them, as Figure 6 and Figure 9 shown, the extrusion assembly 6 includes a rotating sleeve 61 rotatably connected to the second conductive terminal 3. One end of the rotating sleeve 61 adjacent to the mounting base 1 is fixedly provided with a rotating ring 62. A number of first wedges 63 are fixedly connected to the rotating ring 62. A second wedge 64 is arranged on the first wedge 63. A guide rod 65 is fixedly connected to the second wedge 64. A number of guide grooves 66 corresponding to the first wedges 63 are opened on one side of the fixed sleeve 8 opposite to the rotating sleeve 61. The guide rod 65 is slidably connected in the guide groove 66. It should be noted that both the first wedge 63 and the second wedge 64 are arc-shaped wedge structures, and the surface of the second wedge 64 in contact with the first annular airbag 9 is adapted to the inner wall of the first annular airbag 9. Moreover, the distance that the rotating ring 62 squeezes the second wedge 64 to slide along the guide groove 66 is adapted to the thickness of the first annular airbag 9. The outer peripheral surface of the second wedge 64 is adapted to fit the inner circle of the first annular airbag 9 so that when it is lifted by the first wedge 63, it can better squeeze the first annular airbag 9 to achieve the purpose of squeezing the gas in the first annular airbag 9 into a number of second annular airbags 102. It should be added here that a number of second annular airbags 102 are communicated with the first annular airbag 9 (not shown in the figure), and a number of return springs are arranged in the first annular airbag 9. In this way, when disassembling, when the extrusion of the first wedge 63 on the second wedge 64 is released, the first annular airbag 9 will automatically reset, sucking back the gas in a number of second annular airbags 102, making the second annular airbags 102 deflated, and thus pulling the second rubber ring 101 to be clamped into the annular slot 11, which is convenient for disassembly.

[0049] In addition, it is worth mentioning that from Figure 3 、 Figure 5and Figure 8 - Figure 9 It can be seen that the outer wall of the first annular airbag 9 is flush with the outer walls of the rotating sleeve 61 and the fixed sleeve 8, and is made of a hard material. One side of the first annular airbag 9 is fixedly connected to the fixed sleeve 8. The gas discharged by the second wedge block 64 pressing the first annular airbag 9 enters a plurality of waterproof rings 10, which is adapted to the waterproof requirement that the waterproof rings 10 are jacked up and abut against the inner wall of the docking sleeve 22 after being jacked up.

[0050] Then from Figure 5 - Figure 7 It can be seen that the triggering assembly 7 includes a trigger box 71 fixedly connected inside the rotating sleeve 61. A trigger block 72 is slidably connected inside the trigger box 71. A first spring 73 is arranged inside the trigger box 71. One end of the first spring 73 is fixedly connected to the bottom end of the trigger block 72 located inside the trigger box 71, and the other end is fixedly connected to the inner wall of the bottom end of the trigger box 71. The front and rear ends of the trigger block 72 along the axial direction of the rotating sleeve 61 are both wedge-shaped structures, and the height of the trigger block 72 is adapted to the depth of the arc-shaped groove 25.

[0051] Combined with Figure 10 , arc-shaped grooves 25 adapted to the triggering assembly 7 are symmetrically arranged inside the docking sleeve 22. In this way, when the docking sleeve 22 is snapped onto the second conductive terminal 3 or the fixed sleeve 8, the inner wall of the first half of the docking sleeve 22 will squeeze the trigger block 72 into the trigger box 71. Then, when the docking sleeve 22 moves to the position where the arc-shaped groove 25 inside it contacts the trigger block 72, the trigger block 72 pops up and snaps into the arc-shaped groove 25. Due to the oblique arc-shaped structure of the arc-shaped groove 25, during the continuous forward movement of the docking sleeve 22, the trigger block 72 slides inside the arc-shaped groove 25, thereby driving the rotation of the rotating sleeve 61, and then driving the first wedge block 63 to rotate through the rotating ring 62. Then, since the first wedge block 63 and the second wedge block 64 are wedge-shaped structures with each other, the second wedge block 64 will be squeezed so that the guide rod 65 on it slides along the guide groove 66 on the fixed sleeve 8, and then the inner side of the first annular airbag 9 is squeezed.

[0052] Furthermore, referring to Figure 2 、 Figure 11 and Figure 12As shown, a ferrule 12 is further provided on the side of the mounting base 1 away from the first conductive terminal 2. A first annular clamping cavity 13 is formed in the ferrule 12. Limiting blocks 14 are symmetrically arranged on the ferrule 12. The docking sleeve 22 is used to sleeve the fixed sleeve 8. A second annular clamping cavity 21 adapted to the ferrule 12 is further formed in the plug base 4. An extrusion ring 23 adapted to the first annular clamping cavity 13 is arranged in the second annular clamping cavity 21. A first rubber ring 24 is arranged at the front end of the extrusion ring 23 for tightly adhering to the inner wall of the first annular clamping cavity 13. A limiting groove 20 adapted to the limiting block 14 is further formed in the plug base 4 for restricting the docking direction of the docking sleeve 22 and the fixed sleeve 8 in the plug base 4. It should be added that the limiting block 14 is provided for the following reasons: firstly, it is convenient for the docking sleeve 22 to be snapped onto the rotating sleeve 61; secondly, it is convenient to ensure that the clamping component 16 mentioned below is snapped into the first clamping groove 17; thirdly, when the arc-shaped groove 25 on the inner wall of the docking sleeve 22 drives the rotating sleeve 61 to rotate through the triggering block 72, the entire plug base 4 is restricted to only move forward and backward and cannot rotate, so as to ensure that the rotating sleeve 61 and the docking sleeve 22 generate relative rotation. In addition, there is the first rubber ring 24. The reason for setting it as a rubber material and being compressible is that when the extrusion ring 23 is snapped into the first annular clamping cavity 13, the first rubber ring 24 is just squeezed and abuts against the inner wall of the first annular clamping cavity 13, thereby realizing the first layer of waterproof barrier. The above-mentioned several second rubber rings 101 are attached to and tightly abutted against the inner wall of the docking sleeve 22 to realize the second layer of waterproof barrier. And these two layers of barriers are both realized through linkage.

[0053] Furthermore, referring to Figure 2 - Figure 4 As shown, a movable cavity 15 is formed in the mounting base 1. A clamping component 16 is arranged in the movable cavity 15. A control component 18 for controlling the clamping component 16 is further arranged in the mounting base 1. A first clamping groove 17 adapted to the clamping component 16 is formed in the plug base 4. A clamping block 19 adapted to the clamping component 16 is arranged in the first clamping groove 17. The clamping component 16 is snapped into the first clamping groove 17 through the clamping block 19 to prevent the plug base 4 from falling off.

[0054] Among them, the clamping component 16 includes a mounting rod 161 fixedly connected in the moving cavity 15. A clamping rod 162 is rotatably connected to the mounting rod 161. A torsion spring 163 is arranged at the connection between the mounting rod 161 and the clamping rod 162. One end of the torsion spring 163 is fixedly connected to the mounting rod 161, and the other end is fixedly connected to the clamping rod 162. The torsion spring 163 always has a tendency to cause the clamping rod 162 to rotate upward, ensuring that the clamping rod 162 always has a space to rotate upward so that it can always be in a limited state when engaging with the clamping block 19. And the clamping rod 162 has a space to rotate up and down in the moving cavity 15 and the first clamping groove 17. In this way, when the limit between the clamping block 19 and the clamping rod 162 is released, there is space for the rotation of the clamping rod 162. The end of the clamping rod 162 far from the mounting rod 161 extends to the outside of the moving cavity 15 and forms a clamping part with a wedge-shaped structure. The clamping part of the moving cavity 15 is adapted to the clamping block 19.

[0055] The control component 18 includes a control cylinder 181 fixedly connected inside the mounting base 1. A limiting ring 183 is slidably connected to the control cylinder 181. The limiting ring 183 is fixedly connected to the pressing rod 182. The pressing rod 182 is slidably connected in the control cylinder 181 through the limiting ring 183. A second spring 184 is arranged in the control cylinder 181. One end of the second spring 184 is fixedly connected to the bottom end of the limiting ring 183, and the other end is fixedly connected to the inner wall of the bottom end of the control cylinder 181. The pressing rod 182 is arranged directly above the clamping rod 162, and the bottom end of the pressing rod 182 can penetrate and slide through the control cylinder 181 and the moving cavity 15 to squeeze the clamping rod 162 to make it rotate downward. The top end of the pressing rod 182 extends to the outside of the mounting base 1 to form a pressing part for manual pressing.

[0056] It is worth mentioning that, as Figure 3 、 Figure 5 and Figure 10 shown, the length of the arc-shaped groove 25 is adapted to the angle that the first wedge block 63 needs to rotate when it drives the second wedge block 64 to squeeze the first annular airbag 9 through the trigger block 72, and the gas discharged from the first annular airbag 9 meets the requirement of jacking up the waterproof ring 10 to abut against the inner wall of the docking sleeve 22. Combining the above description of the first annular airbag 9, that is to say, when the trigger block 72 moves to the end in the arc-shaped groove 25, it drives the first wedge block 63 to squeeze the first annular airbag 9 through the second wedge block 64. At this time, the gas extruded from the first annular airbag 9 is just enough for a number of second annular airbags 102 to use, so that the second rubber ring 101 on it abuts against the inner wall of the docking sleeve 22. And then combining Figure 11 and Figure 12As shown, when the arc-shaped groove 25 starts to come into contact with the trigger block 72, the limit block 14 starts to come into contact with the limit groove 20; secondly, when the trigger block 72 reaches the end of the arc-shaped groove 25, the limit block 14 completely enters the docking sleeve 22, and at this time, the engaging assembly 16 is engaged with the engaging block 19 in the first card slot 17.

[0057] The usage process of this product:

[0058] During specific use, align the docking sleeve 22 of the plug base 4 and snap it into the rotating sleeve 61. When the second annular card cavity 21 is about to contact the card sleeve 12, adjust the plug base 4 so that the limit groove 20 on it snaps onto the limit block 14, and then continue to push. At this time, the trigger block 72 just snaps into the arc-shaped groove 25, and then the limit block 14 is engaged with the limit groove 20 to limit the rotation of the plug base 4. Thus, during the process of the plug base 4 being continuously pushed and snapped in, the trigger block 72 drives the rotating sleeve 61 to rotate, and then drives the first wedge block 63 to squeeze the second wedge block 64, so that the inner side of the first annular airbag 9 is squeezed, and the gas inside it is discharged into several second annular airbags 102. Then, the second annular airbags 102 are inflated to lift the second rubber ring 101, so that it is lifted from the annular card slot 11 and fits against the inner wall of the docking sleeve 22. When the first rubber ring 24 snaps in and presses tightly against the inner wall of the first annular card cavity 13, at this time, the engaging rod 162 also just snaps onto the engaging block 19 in the first card slot 17, completing the limitation of the plug base 4. At this time, the gas in the first annular airbag 9 is just squeezed into several second annular airbags 102. At this time, the second rubber ring 101 completes the work of pressing tightly against the inner wall of the docking sleeve 22, and the first rubber ring 24 is squeezed to press tightly against the inner wall of the first annular card cavity 13, thereby realizing a double-layer waterproof barrier. Moreover, during the pushing process, the second rubber ring 101 slowly rises from the annular card slot 11 to press tightly against the inner wall of the docking sleeve 22, so the wear on the inner wall of the docking sleeve 22 will be greatly reduced, and it is convenient for installation and disassembly;

[0059] When disassembling, just press the pressing rod 182, and then squeeze the engaging rod 162 to make it disengage from the engaging block 19, and then the plug base 4 can be pulled out.

[0060] Furthermore, it effectively solves the problem that the rubber rings in the existing energy storage connectors cannot meet the usage requirements of waterproofing and convenient installation and disassembly.
