Description

Technical Field

[0001] This utility model relates to the field of data acquisition equipment technology, and in particular to a standardized data acquisition device that is compatible with multiple communication interfaces. Background Technology

[0002] The data acquisition unit is a core communication component for real-time monitoring of the integrated photovoltaic and energy storage system. It can collect key parameters such as voltage, current, power, and temperature, providing strong data support for users to optimize equipment performance and provide fault early warning through cloud-based energy management systems. Typically, the data acquisition unit has a primary interface for data transmission. These primary interfaces come in various types, suitable for wired or wireless data transmission methods, to adapt to different application scenarios.

[0003] In existing technologies, data acquisition devices need to be configured with different types of primary communication interfaces to meet the needs of different application scenarios. For example, long-distance wired transmission typically uses RS485 or RJ45 primary interfaces, while wireless primary interfaces such as WiFi, Bluetooth, and 4G / 5G can be used in scenarios with limited cabling or for short-distance transmission.

[0004] Existing data acquisition devices all have casings adapted to a specific interface shape. Therefore, the casing structures of data acquisition devices with different interface types vary, requiring a complete redesign and manufacturing of the casing for each type of interface. This significantly increases the manufacturing difficulty and cost of data acquisition devices. The root of this problem lies in the lack of standardized design, which prevents modular configurations that allow for multiple uses from a single casing, thus hindering the large-scale production and cost control of data acquisition devices.

[0024] This utility model has the following beneficial effects:

[0025] 1. The same housing design is compatible with multiple control panels, reducing mold design and manufacturing costs.

[0026] To meet different communication needs, the standardized data acquisition unit, which is compatible with multiple communication interfaces, uses control panels with different chips. When the interfaces of the control panels are different, they can all be housed within the casing, achieving the effect of adapting multiple control panels to the same casing. This significantly reduces manufacturing costs and mold design costs, and improves the standardization of the product and production efficiency. In addition, the modular design makes the standardized data acquisition unit, which is compatible with multiple communication interfaces, highly adaptable. It can flexibly configure the corresponding control panels according to different application scenarios and communication needs, meet diverse market demands, and facilitate equipment maintenance, upgrades, and replacements.

[0027] 2. Multiple sealing design protects the internal circuitry from the influence of the external environment.

[0028] The assembly structure of the housing body, sealing claws, tail nut, and sealing plug significantly improves the sealing effect. The sealing plug is made of flexible material and has a tear-out design, which not only ensures the integrity of the seal but also facilitates the installation of the wire harness. The claw structure of the sealing claw applies uniform radial pressure to the sealing plug under the locking action of the tail nut, forming a multi-layer sealing structure that effectively prevents external impurities such as dust and rainwater from entering the housing and protects the control panel from contamination.

[0029] 3. Equipped with anti-misassembly protection function to improve product reliability.

[0030] The design incorporates foolproof structures inside and at the ends of the housing, effectively preventing incorrect installations such as misconnection or reverse insertion of the control panel. This multi-layered foolproof design not only protects the various components from damage but also ensures the normal operation of the standardized data acquisition unit that is compatible with multiple communication interfaces, thereby improving the reliability of the product.

[0031] 4. Quick-release and plug-and-play connection design improves installation and maintenance efficiency.

[0032] The connector and control panel adopt a plug-in assembly for quick assembly and disassembly. The connector has an eccentric groove to prevent the control panel from being inserted backwards. At the same time, the conductive socket formed by the V-shaped metal clip cooperates with the metal solder feet of the control panel to provide a stable, reliable, and low-impedance dynamic electrical connection interface, realizing "blind plug" quick installation, which effectively improves installation efficiency and connection reliability.

[0053] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0054] like Figure 1 and Figure 2 As shown, this embodiment provides a standardized data acquisition device adaptable to multiple communication interfaces, including a housing 1, a control panel 2, a sealing plug 3, a sealing claw 4, a tail nut 5, and a connector 6. The housing 1 has a hollow structure, with both its first and second ends open, forming an internal cavity to accommodate the control panel 2. The first end of the housing 1 is a reduced-diameter connector 11 for mating with the tail nut 5, and the second end of the housing 1 is fitted with the connector 6 for connecting to external devices. The control panel 2 is located within the cavity, with an interface at one end facing the connector 11. The interface connects to a wireless network antenna, an RS485 serial bus, or an RJ45 network cable for connecting the control panel 2 to external devices. Furthermore, depending on different communication requirements, the control panel 2 can be equipped with different chips, such as 4G / 5G, WIFI, Bluetooth, or Ethernet synchronization. When the interfaces are different, there is no need to design different structures for the housing 1 according to different types of control panels 2, which reduces the manufacturing difficulty and cost of standardized data acquisition devices that adapt to multiple communication interfaces. The assembly structure provided in this embodiment can make the control panel 2 fit inside the housing 1, which is highly adaptable and easy to install. No precise alignment operation is required, which effectively improves the installation efficiency.

[0055] The tail nut 5 is sleeved on the sealing claw 4 and threadedly connected to the connector 11. As mentioned above, the connector 11 at one end of the housing 1 can not only mate with the tail nut 5, but also be used for precise installation and quick alignment after assembly with both the sealing plug 3 and the sealing claw 4. Therefore, in this embodiment, as... Figure 1 and Figure 3 As shown, on the one hand, to accommodate the tail nut 5, an external thread 111 is provided on the outer wall of the connector 11 for threaded connection and locking; on the other hand, to install with the sealing claw 4 and to prevent the tail nut 5 from rotating and causing the sealing claw 4 to rotate after installation, the end of the connector 11 away from the housing 1 adopts a second tooth groove 113 structure to achieve meshing with the sealing claw 4 and achieve an effective anti-rotation effect. Furthermore, an installation and positioning structure for the sealing plug 3 is also provided. An annular positioning edge 112 is integrally extended horizontally towards the center on the inner wall of the connector 11 near the housing 1. After installation, the top of the sealing plug 3 abuts against the positioning edge 112 to achieve a limiting effect.

[0056] Immediately afterwards, such as Figures 1-5As shown, in this embodiment, a sealing plug 3 is provided to facilitate the passage of the wire harness and to accommodate and lock the wire harness. The sealing plug 3 is coaxially arranged with the connector 11. Part of the sealing plug 3 extends into the connector 11 and abuts against the inner wall of the connector 11, while the other part extends to the outside of the connector 11. A through hole 31 for the wire harness to pass through is provided at the end of the sealing plug 3 away from the housing 1. The through hole 31 is fitted with the outer diameter of the wire harness with an interference fit / slight interference fit to avoid slippage at the sealing end.

[0057] Specifically, the sealing plug 3 is stepped, comprising a head 32 and a body 33 arranged sequentially along the axial direction of the sealing plug 3. A through hole 31 is provided at the tail end of the body 33. The sealing plug 3 can be made of flexible materials such as rubber or resin, and this embodiment does not limit this. The head 32 is integrally disposed on the end of the body 33 near the housing 1 and extends horizontally towards the outer side, and the diameter of the head 32 is larger than the diameter of the body 33. After installation, the end of the head 32 of the sealing plug 3 facing away from the body 33 abuts against the positioning edge 112, while the body 33 is annularly arranged, forming a cavity inside to accommodate the wire harness. The end of the body 33 away from the housing 1 is provided with a recessed positioning groove 35, and a through hole 31 for the wire harness to pass through is opened at the bottom. Furthermore, in this preferred embodiment, considering the looseness of the wire harness structure or the lack of a unified positioning head, a tear-out 34 is provided on the sealing plug 3. The tear-out 34 extends through the sealing plug 3 along its axial direction, that is, an integral tear-out 34 is provided on the head 32 and the body 33, ensuring the integrity of the seal and preventing external dust, rainwater and other impurities from entering the housing 1 through the connector 11 and contaminating the control panel 2. At the same time, it can also avoid installing the wire harness by passing it through. When installing the wire harness, the sealing plug 3 can be peeled off and wrapped around the wire harness, which helps to seal the wire harness and also reduces bending and wear of the wire harness at the entrance and exit, improving installation efficiency. Thus, the sealing plug 3 integrates functions such as sealing, protection, locking and convenient installation.

[0058] It should be specifically noted that in this embodiment, the sealing claw 4 is sleeved outside the sealing plug 3, and the end of the sealing claw 4 facing the connector 11 is correspondingly embedded in the connector 11, so that the sealing plug 3 is sleeved inside the sealing claw 4 to form a mating structure, and the sealing claw 4 can lock the sealing plug 3 under the action of the tail nut 5, thereby achieving the purpose of locking the wire harness inside the sealing plug 3. Therefore, as follows... Figure 1 , Figure 6 and Figure 9As shown, the sealing claw 4 is sequentially provided with an integral fixing ring 41 and claw body 42 along the direction away from the housing 1. One end of the fixing ring 41 is correspondingly embedded in the connector 11, and the other end is connected to multiple claw bodies 42, which are spaced apart around the circumference of the fixing ring 41. A first toothed groove 411 is provided on the outer wall of the fixing ring 41 near the claw body 42, and a second toothed groove 113 is provided at the end of the connector 11. During assembly, the first toothed groove 411 and the second toothed groove 113 engage and connect, thereby fixing the sealing claw 4 to the housing 1, preventing the sealing claw 4 from moving into the housing 1, and preventing the tail nut 5 from rotating and causing the sealing claw 4 to rotate.

[0059] Specifically, a first groove 411 is provided on the outer wall of the fixing ring 41, and multiple first grooves 411 are provided around the circumference of the fixing ring 41. Multiple second grooves 113 are provided around the end of the housing 1. The first grooves 411 and the second grooves 113 are connected in a one-to-one meshing manner. By providing multiple first grooves 411 and second grooves 113, the stability of the connection between the sealing claw 4 and the housing 1 is improved. The end of the fixing ring 41 near the housing 1 extends into the interior of the connector 11 of the housing 1. The outer wall of the fixing ring 41 fits against the inner wall of the connector 11, further improving the stability of the connection between the fixing ring 41 and the housing 1. The inner wall of the fixing ring 41 fits against the outer wall of the sealing plug 3, improving the sealing performance between the fixing ring 41 and the sealing plug 3.

[0060] Specifically, one end of the claw body 42 is connected to the fixing ring 41, and the other end extends along the length of the housing 1. A limiting protrusion 421 is provided on the inner wall of the end of the claw body 42 away from the fixing ring 41. That is, the end of the claw body 42 away from the fixing ring 41 forms a limiting end facing inward. The end of the sealing plug 3 away from the housing 1 is provided with a reduced diameter positioning groove 35. When the sealing plug 3 and the sealing claw 4 are installed together, the limiting protrusion 421 is engaged in the positioning groove 35 of the sealing plug 3. Under the guiding action of multiple claw bodies 42, the sealing plug 3 is guided to slide easily into the correct position, forming a quick mating effect.

[0061] Furthermore, after the tail nut 5 is connected to the housing 1, the inner wall of the tail nut 5 abuts against the outer wall of the claw body 42, thereby abutting the inner wall of the claw body 42 against the outer wall of the sealing plug 3 to seal and fix the sealing plug 3. The tail nut 5 is sleeved on the outside of the sealing claw 4 and threadedly connected to the connector 11. When tightening continues, the small diameter section 52 is pushed towards the housing 1, reducing the gap between adjacent claw bodies 42, so that the sealing claw 4 tightly wraps the wire bundle wrapped inside the sealing plug 3.

[0062] Based on the above objectives, such as Figure 1 , Figure 3 and Figure 7As shown, in this embodiment, the tail nut 5 is provided with a large-diameter section 51 and a small-diameter section 52 sequentially along the axial direction away from the sealing plug 3. Specifically, the inner wall of the large-diameter section 51 is provided with an internal thread that mates with the external thread 111; the small-diameter section 52 can abut against the sealing claw 4, thereby causing the sealing claw 4 to abut against the outer wall of the sealing plug 3 to seal and fix the sealing plug 3. An inclined transition section is provided between the large-diameter section 51 and the small-diameter section 52, which guides the claw body 42 to tighten. Specifically, the inner diameter of the small-diameter section 52 is less than or equal to the outer diameter of the multiple claw bodies 42 after tightening, so that when the tail nut 5 is rotated and locked, the small-diameter section 52 can abut against the sealing claw 4. During installation, the large-diameter section 51 faces the housing 1, and the small-diameter section 52 of the tail nut 5 moves towards the side closer to the housing 1 as it rotates. Since the end of the sealing plug 3 facing the housing 1 abuts against the positioning edge 112, the first tooth groove 411 of the sealing claw 4 and the second tooth groove 113 of the housing 1 mesh together. The small-diameter section 52 gradually approaches and squeezes the claw body 42, causing the claw body 42 to converge inwards, thus sealing and pressing the inner wall of the claw body 42 tightly against the outer wall of the sealing plug 3. By simultaneously and evenly squeezing multiple claw bodies 42 inwards, a uniform and strong radial pressure is applied to the outer wall of the sealing plug 3, significantly improving the mechanical interlocking and sealing effect between the sealing plug 3 and the wire harness.

[0063] In this embodiment, as Figure 1 , Figure 3 and Figure 8 As shown, connector 6 is installed at the second end of housing 1 and is electrically connected to control panel 2. Connector 6 and control panel 2 are assembled using a plug-in method for quick assembly and disassembly. Considering both sealing and tackiness, connector 6 is provided with an outer connecting end 61, a positioning protrusion 62, and an inner connecting end 63 sequentially along the axial direction near the sealing plug 3. The outer connecting end 61 is used to connect external devices, and the inner connecting end 63 extends into the opening at the second end of housing 1. After installation, the outer circumference of the positioning protrusion 62 is flush with the outer wall of housing 1, and the positioning protrusion 62 abuts against the second end of housing 1 and is fixedly connected to housing 1 by screws.

[0064] Next, a sealing ring 7 is provided between the inner connecting end 63 and the housing 1. The sealing ring 7 is sleeved on the outer wall of the inner connecting end 63, and in its natural state, the outer diameter of the sealing ring 7 is larger than the inner diameter of the housing 1. The outer side of the sealing ring 7 abuts against the inner wall of the housing 1, forming a sealed connection with the housing 1 to prevent dust, rainwater, and other impurities from entering the housing 1. In other embodiments, the connector 6 and the housing 1 can also achieve a sealed connection by means of an interference fit.

[0065] Optionally, the control panel 2 is provided with a connector at the end away from the above interface. The connector can be connected to an external device, so that the control panel 2 can be connected to two external devices at the same time to realize the data transmission between the two external devices.

[0066] Specifically, the connector is a metal solder joint on the control panel 2. A groove 64 for inserting the control panel 2 is provided on the side of the inner connection end 63 facing away from the outer connection end 61. The groove 64 is offset relative to the center of the inner connection end 63, and the control panel 2 is inserted into the groove 64. A conductive socket 65 electrically connected to the control panel 2 is installed in the groove 64. Since two metal solder joints (connectors) are spaced apart along the width direction of the control panel 2 on the side near the connector 6, two sets of conductive sockets 65 are provided in the groove 64 to match, with the metal solder joints and conductive sockets 65 corresponding to each other. Furthermore, the conductive socket 65 includes two metal clips, which are V-shaped and electrically connected. When the connector 6 is connected to the control panel 2, the opposite sides of the two metal clips abut against the metal solder joints on both sides of the control panel 2, providing a stable, reliable, low-impedance dynamic electrical connection interface, achieving quick, simple, and "blind-plug" installation, and accelerating production efficiency.

[0067] In addition, such as Figure 1 , Figure 2 , Figure 8 and Figure 9 As shown, this embodiment also includes multiple anti-misfit structures to prevent incorrect connections and reverse insertions, improving quick assembly and disassembly while protecting various components. On one hand, symmetrical anti-misfit partitions 12 are provided on the inner wall of the first end of the housing 1, each partition 12 having a first anti-misfit groove 13, and the control panel 2 is snapped into the first anti-misfit groove 13. Both anti-misalignment partitions 12 extend along the thickness direction of the housing 1. The first anti-misalignment groove 13 is set on the side wall of the anti-misalignment partition 12 and is set along the thickness direction of the housing 1 near the edge of the anti-misalignment partition 12. Since the pin heights of the electrical components on the front and back of the control panel 2 are different, the operator does not need to judge the interface direction. He can simply push it in along the center line of the housing 1 and lock it in place. Therefore, the end of the control panel 2 facing the tail nut 5 needs to be placed in the housing 1 in a specific direction to lock it in with the first anti-misalignment groove 13. For this purpose, the line connecting the pair of first anti-misalignment grooves 13 is parallel and adjacent to the corresponding center line of the housing 1. This can effectively prevent the control panel 2 from being installed backwards. It can also prevent the standardized data acquisition device that is compatible with multiple communication interfaces from being unusable when the control panel 2 is installed backwards. It can also improve the stability of the installation of the control panel 2 and enable the quick installation of the control panel 2.

[0068] On the other hand, a second anti-mistake groove 14 is provided at the second end of the housing 1. Correspondingly, an anti-mistake protrusion 66 is provided on the side of the positioning protrusion 62 of the connector 6 facing the inner connection end 63. During installation, the anti-mistake protrusion 66 is engaged in the second anti-mistake groove 14 to prevent the connector 6 from being installed backwards, which would cause the standardized data acquisition device that adapts to multiple communication interfaces to be unusable.

[0069] During assembly, first push the control panel 2 into the cavity of the housing 1 in the direction of the first anti-fooling groove 13, then position the sealing plug 3 in place from the direction of the connector 11, then put the sealing claw 4 on the outside of the sealing plug 3 and engage with the second tooth groove 113, align the tail nut 5 and tighten it to the small diameter section 52 to press the claw body 42; finally, blindly insert the connector 6 from the second end of the housing 1 into place, and the sealing ring 7 fits against the inner wall of the housing 1 to form a seal.

[0070] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
