Description

Technical Field

[0001] This invention relates to the field of copper busbar connector technology, specifically to a fixed energy storage soft copper busbar connector assembly. Background Technology

[0002] Energy storage flexible copper busbar connectors are conductive components used in energy storage systems to connect key components such as battery modules, inverters, and distribution cabinets. Their core function is to ensure efficient and stable current transmission, while also taking into account ease of installation and system safety. As the "blood vessels" of the energy storage system, the performance of energy storage flexible copper busbar connectors directly affects the system efficiency and safety.

[0003] Prior art (Chinese patent No. CN204538332U, published on 2015-08-05) discloses a novel flexible high-voltage connector, which includes a flexible copper busbar, a terminal block, and a cable. The flexible copper busbar includes an elastic arm. The feature is that the flexible copper busbar is connected to the terminal block, the front end of the terminal block is connected to the flexible copper busbar, the rear end of the terminal block is connected to the cable, and the elastic arm is located in the middle of the flexible copper busbar and can be bent within a certain angle range, so that the connector can be bent within a certain angle, making the contact more reliable, improving the flexibility of product use and installation, and making the product more user-friendly. Meanwhile, the product's size and internal resistance are reduced, effectively lowering energy consumption. Furthermore, prior art (Chinese patent CN218275296U, published on 2023-01-10) discloses a flexible, bendable rectangular waterproof quick-connect, including a male assembly and a female assembly. The male assembly includes a soft copper busbar, heat-shrink tubing, a male plastic shell, and a connector. The female assembly includes a female plastic shell and a female conductor. The male and female assemblies use a snap-fit ​​structure, automatically locking after assembly, offering easy installation and disassembly. The waterproof design of the quick-connect allows the product to withstand harsh operating environments. The soft copper busbar in the middle can be bent arbitrarily, allowing the quick-connect to avoid interference points, making assembly and installation convenient and quick, while also improving short-distance fault tolerance.

[0004] While existing technologies are convenient and quick to assemble and install, they employ an assembly-type structure, resulting in inconsistent waterproof performance. Furthermore, apart from the pull-out force generated by riveting with the soft copper busbar, there are no other holding structures, leading to poor assembly stability.

[0005] Therefore, a fixed energy storage soft copper busbar connector assembly is proposed to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide a fixed energy storage soft copper busbar connector assembly to solve the problems mentioned in the background art, such as the current market's assembly-type structure, poor consistency in waterproof performance, and poor assembly stability due to the lack of other fixed structures besides the pull-out force generated by riveting with the soft copper busbar.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a fixed-type energy storage flexible copper busbar connector assembly, comprising a flexible copper busbar body, power terminal bodies being riveted and assembled on the left and right sides of the flexible copper busbar body, and power terminal anti-touch fingers being riveted and assembled inside the power terminal bodies; and an integrated rubber-coated shell being assembled on the outer sides of the flexible copper busbar body, the power terminal bodies, and the power terminal anti-touch fingers; the rubber-coated shell having an auxiliary groove in a ring array on the outer side of the power terminal bodies, and a holding mechanism being provided inside the auxiliary grooves; the holding mechanism increasing the holding force on the power terminal bodies by moving the auxiliary suction plate included therein; and a blocking mechanism being provided on one side of the end of the rubber-coated shell at the end of the flexible copper busbar body, the blocking mechanism further limiting the flexible copper busbar body by means of the inclined locking plate included therein.

[0008] Preferably, the outer ring of the power terminal body is provided with a retaining groove, and the inner side of the rubber-coated shell is provided with a limiting protrusion. The limiting protrusion is adapted to the position of the retaining groove, and the limiting protrusion fills the interior of the retaining groove. The limiting protrusion and the retaining groove cooperate with each other to initially increase the retaining force of the power terminal body.

[0009] Preferably, the holding mechanism includes a fixing box, which is fixedly connected inside the auxiliary slots arranged in an annular array, with the inner side of the fixing box fitting against the inside of the auxiliary slots, and a connecting rod slidably connected to the outer side of the fixing box. At the same time, an auxiliary suction plate for increasing the holding force of the power terminal body is fixedly connected to the outer end of the connecting rod.

[0010] Preferably, the auxiliary suction plate is made of a flexible structural material, and the auxiliary suction plate is not compressed and is arranged in an arch shape, with its arched opening facing one side of the power terminal body. When the auxiliary suction plate contacts the power terminal body, the inner side of the auxiliary suction plate and the outer side of the power terminal body are in contact with each other.

[0011] Preferably, the inner end of the connecting rod is fixedly connected to an air supply plate, and the air supply plate is slidably connected inside the fixed box. The internal cavity of the fixed box is rectangular in shape, and the side of the air supply plate is in close contact with the inside of the fixed box cavity. A return spring is fixedly connected between the inner side of the air supply plate and the internal cavity of the fixed box, and the return spring can apply a reaction force to the air supply plate.

[0012] Preferably, a connecting hose is connected through the outer side of the fixing box, and the other end of the connecting hose is connected through the auxiliary suction plate. The auxiliary suction plate has an air suction hole on the side near the power terminal body, and the air suction hole is connected to the internal cavity of the fixing box through the connecting hose.

[0013] Preferably, the gas supply plate forms an elastic structure with the fixed box through a return spring, and the gas supply plate forms a sliding structure with the fixed box through a connecting rod. The movement of the gas supply plate realizes the suction of gas, thereby performing negative pressure adsorption and fixation on the power terminal body.

[0014] Preferably, the blocking mechanism includes a positioning groove, which is located at the end of the soft copper busbar body (in the rubber-coated housing), and two sets of positioning grooves are symmetrically distributed about the center point of the soft copper busbar body. The inclined card plate is fixedly connected inside the positioning groove.

[0015] Preferably, the inclined plate is arranged in an inclined structure, and the inclined plate is inclined from one side of the positioning groove to the inner side of the rubber-coated housing. The end side of the soft copper busbar body is fixedly connected with a fixing protrusion, and the fixing protrusion and the inclined plate are distributed in a one-to-one correspondence.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] The soft copper busbar body, power terminal body, and power terminal anti-touch finger are assembled using a riveting assembly process. At the same time, the encapsulated shell is assembled using an integrated encapsulation process. This not only improves the stability of each component after assembly but also solves the problem of structural variation. Furthermore, the integrated encapsulation structure improves the waterproof rating of the equipment.

[0018] When the rubber-coated housing comes into contact with the power terminal body, the power terminal body abuts against the auxiliary suction plate, causing it to deform. The originally slightly arched auxiliary suction plate becomes flush with the outside. Under the action of abutment, the auxiliary suction plate drives the connecting rod to slide along the fixed box, which in turn drives the air supply plate to move inward and squeeze the return spring, causing it to deform. After the rubber-coated housing is assembled, the air supply plate, driven by the return spring, applies a reaction force to the auxiliary suction plate through the connecting rod, allowing the auxiliary suction plate to better fit the side of the power terminal body, achieving fixation and improving assembly stability.

[0019] After the initial assembly of the rubber-coated housing and the power terminal body, the limiting protrusions on the inner side of the rubber-coated housing will fill the retaining groove on the outer side of the power terminal body. The retaining groove and the limiting protrusions cooperate with each other to increase the retaining force of the power terminal body.

[0020] When the air supply plate moves inward along the fixed box due to compression, it will simultaneously perform a suction action on the gas inside the fixed box. Since the connecting hose is connected to the auxiliary suction plate and communicates with the inside of the fixed box, the auxiliary suction plate simultaneously sucks the gas in front of the auxiliary suction plate through the suction hole and the connecting hose, forming a negative pressure environment on the outside of the power terminal body, thereby achieving negative pressure adsorption and fixation, effectively further improving the fixation effect on the power terminal body.

[0021] When assembling the soft copper busbar body with the rubber-coated housing, as the soft copper busbar body extends into the rubber-coated housing, the fixing protrusion fixed on the outer side of the soft copper busbar body can move along the inclined direction of the inclined clamping plate. At this time, the soft copper busbar body can smoothly dock with the rubber-coated housing. Meanwhile, since the inclined clamping plate is set with an inclined structure, it can limit and block the fixing protrusion, thereby further preventing the soft copper busbar body from slipping off the rubber-coated housing and further improving the stability of the assembly between the rubber-coated housing and the soft copper busbar body.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Example 1: As Figure 1 , Figure 2 and Figure 7 The present invention provides the following technical solution: a fixed energy storage soft copper busbar connector assembly, wherein: power terminal bodies 2 are riveted and assembled on the left and right sides of the soft copper busbar body 1, and power terminal anti-touch finger 3 is riveted and assembled inside the power terminal body 2; and an integrated rubber-coated shell 4 is assembled on the outer side of the soft copper busbar body 1, the power terminal body 2 and the power terminal anti-touch finger 3, the power terminal body 1, the power terminal body 2 and the power terminal anti-touch finger 3, the power terminal body 1, the power terminal body 2 and the power terminal anti-touch finger 3 are integrally rubber-coated, the power terminal body 2 is provided with a retaining groove 5 on the outer ring, and the inner side of the rubber-coated shell 4 is provided with a limiting protrusion 11, and the limiting protrusion 11 is adapted to the position of the retaining groove 5. At the same time, the limiting protrusion 11 fills the interior of the retaining groove 5, and the limiting protrusion 11 and the retaining groove 5 cooperate with each other to initially increase the retaining force of the power terminal body 2.

[0036] The soft copper busbar body 1, the power terminal body 2, and the power terminal anti-touch finger 3 are assembled using a riveting assembly process. At the same time, the coated housing 4 is assembled using an integrated coating process. This not only improves the stability of each component after assembly but also solves the problem of structural variation. The integrated coating structure also improves the waterproof rating of the equipment. After the initial assembly process of the coated housing 4 and the power terminal body 2 is completed, the carefully designed limiting protrusion 11 on the inner side of the coated housing 4 will accurately embed into the pre-opened retaining groove 5 on the outer side of the power terminal body 2. This structural design of the retaining groove 5 and the limiting protrusion 11 working together can significantly enhance the holding force of the power terminal body 2 in the assembly structure, effectively improving the stability and reliability of the overall assembly.

[0037] Example 2: To further improve the holding force between the power terminal body 2 and the rubber-coated housing 4, a holding mechanism is provided. This holding mechanism ensures the stability of the assembly of the power terminal body 2 and the rubber-coated housing 4. Figures 5-11 The present invention provides the following technical solution: a fixed-type energy storage soft copper busbar connector assembly, comprising: an auxiliary groove 12 arranged in an annular array on the outside of the power terminal body 2, and a fixing mechanism provided inside the auxiliary groove 12. The fixing mechanism increases the fixing force on the power terminal body 2 by moving the auxiliary suction plate 8 included therein. The fixing mechanism includes a fixing box 13, which is fixedly connected inside the annular array of auxiliary grooves 12, and the inner side of the fixing box 13 is in contact with the inside of the auxiliary groove 12. A connecting rod 15 is slidably connected to the outer side of the fixing box 13, and the outer end of the connecting rod 15 is fixedly connected to an auxiliary suction plate 8 for increasing the fixing force on the power terminal body 2. The auxiliary suction plate 8 is made of a flexible material and is not compressed and is arranged in an arch shape, with its arched opening facing one side of the power terminal body 2. When the auxiliary suction plate 8 contacts the power terminal body 2, the inner side of the auxiliary suction plate 8 is in contact with the outer side of the power terminal body 2. The connecting rod 15 is fitted together with an air supply plate 14 fixedly connected to its inner end. The air supply plate 14 is slidably connected inside the fixed box 13, and the internal cavity of the fixed box 13 is rectangular. The sides of the air supply plate 14 are in close contact with the inside of the cavity of the fixed box 13. A return spring 17 is fixedly connected between the inner side of the air supply plate 14 and the internal cavity of the fixed box 13. The return spring 17 can apply a reaction force to the air supply plate 14. A connecting hose 10 is connected through the outer side of the fixed box 13. The other end of the tube 10 is connected to the auxiliary suction plate 8, and the auxiliary suction plate 8 has a suction hole 9 on the side near the power terminal body 2. The suction hole 9 is connected to the internal cavity of the fixed box 13 through the connecting hose 10. The air supply plate 14 forms an elastic structure with the fixed box 13 through the return spring 17, and the air supply plate 14 forms a sliding structure with the fixed box 13 through the connecting rod 15. The air supply plate 14 is moved to achieve the suction of gas, thereby performing negative pressure adsorption and fixation on the power terminal body 2.

[0038] When the rubber-coated housing 4 contacts the power terminal body 2, the power terminal body 2 will abut against the auxiliary suction plate 8, causing the auxiliary suction plate 8 to deform appropriately. At this time, the auxiliary suction plate 8, which was originally slightly arched, will deform to fit against its own outer side. At the same time, under the abutment of the power terminal body 2, the auxiliary suction plate 8 will drive the connecting rod 15 to slide along the fixing box 13, and then drive the air supply plate 14 to move inward along the fixing box 13 through the connecting rod 15. During the inward movement of the air supply plate 14, the return spring 17 will be squeezed simultaneously, causing it to undergo elastic deformation. After the rubber-coated housing 4 is assembled, under the drive of the elastic action of the return spring 17, the air supply plate 14 will apply a reaction force to the auxiliary suction plate 8 through the connecting rod 15, so that the auxiliary suction plate 8 can better fit against the side of the power terminal body 2, thereby firmly holding the power terminal body 2 and improving its assembly stability.

[0039] When the air supply plate 14 is compressed by an external force, it moves smoothly and precisely inward along the pre-set guide structure inside the fixed box 13. During this inward movement, due to the relative motion between the air supply plate 14 and the internal space of the fixed box 13, and the certain degree of sealing between them, the air supply plate 14 acts like a highly efficient piston, synchronously drawing gas from inside the fixed box 13. As the air supply plate 14 continues to move, the gas pressure inside the fixed box 13 gradually decreases. One end of the connecting hose 10 is tightly connected to the suction hole 9 of the auxiliary suction plate 8, while the other end is securely connected to the inside of the fixed box 13, forming a complete and closed gas flow channel. As the internal gas pressure of box 13 decreases, the auxiliary suction plate 8 draws in the gas in front of it through the gas flow channel. As the gas is continuously drawn in, the gas pressure in front of the auxiliary suction plate 8 drops rapidly, thus forming a significant negative pressure area on the outside of the power terminal body 2. The negative pressure environment generates a strong adsorption force, tightly adsorbing the power terminal body 2 onto the front of the auxiliary suction plate 8, thereby providing a more uniform and stable fixing force. This significantly improves the holding effect of the power terminal body 2, ensuring that the power terminal body 2 can always maintain a stable position without loosening or displacement, thus guaranteeing the reliability and stability of the entire electrical system.

[0040] Example 3: To prevent the rubber-coated housing 4 from loosening from the soft copper busbar body 1, a blocking mechanism is provided. This blocking mechanism improves the stability of the assembly between the rubber-coated housing 4 and the soft copper busbar body 1. Figures 2-5The present invention provides the following technical solution: a fixed energy storage flexible copper busbar connector assembly, wherein: a blocking mechanism is provided on one side of the end of the flexible copper busbar body 1 by means of an insulated housing 4, the blocking mechanism further limits the flexible copper busbar body 1 by means of the inclined locking plate 7 included therein, the blocking mechanism includes a positioning groove 16, the positioning groove 16 is opened at the end of the insulated housing 4 located at the end of the flexible copper busbar body 1, and two sets of positioning grooves 16 are symmetrically distributed about the center point of the flexible copper busbar body 1, the inclined locking plate 7 is fixedly connected inside the positioning groove 16, the inclined locking plate 7 is inclined in a tilted structure, and the inclined locking plate 7 is inclined from one side of the positioning groove 16 toward the inside of the insulated housing 4, a fixing protrusion 6 is fixedly connected to the end side of the flexible copper busbar body 1, and the fixing protrusion 6 and the inclined locking plate 7 are distributed in a one-to-one correspondence.

[0041] During the assembly of the flexible copper busbar body 1 and the rubber-coated housing 4, when the flexible copper busbar body 1 is inserted into the rubber-coated housing 4, the fixing protrusion 6 fixed on the outer side of the flexible copper busbar body 1 will move according to the tilting direction of the tilting plate 7. This specific movement method ensures that the flexible copper busbar body 1 can accurately and smoothly dock to the preset position inside the rubber-coated housing 4. The tilting plate 7 adopts an inclined structure design. After the fixing protrusion 6 moves to the appropriate position, its unique tilting structure can effectively limit and block the fixing protrusion 6. This limiting mechanism can effectively prevent the flexible copper busbar body 1 and the rubber-coated housing 4 from slipping due to external forces or vibrations during subsequent use, thereby significantly improving the stability of the assembly of the rubber-coated housing 4 and the flexible copper busbar body 1 and ensuring the reliable operation of the entire electrical connection system.

[0042] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
