Description

Technical Field

[0001] This application relates to the field of power distribution equipment technology, and in particular to a detection component and power distribution equipment. Background Technology

[0002] Power distribution equipment typically incorporates various detection components to monitor the flow of electricity. These components can be CT sensors, Hall effect sensors, and so on. In related technologies, the assembly of these detection components often requires first assembling the circuit board, then installing the busbar and threading it through the sensor on the circuit board. However, due to the limited installation space within the power distribution equipment, the busbar is prone to colliding with the sensor during its threading, leading to sensor damage. This necessitates constant adjustments to the angle and position of the busbar by production and installation personnel, wasting considerable time. Utility Model Content

[0003] In view of this, this application provides a detection component and power distribution equipment to improve the technical problems of complex installation and low installation efficiency of existing detection components.

[0004] One embodiment of this application provides a detection component. The detection component is applied to power distribution equipment, which has a housing. The detection component includes a busbar and a circuit board. The busbar has multiple branches, and the circuit board has multiple sensors, with each branch corresponding to one sensor. The circuit board is configured to be integrally formed with the busbar and fixed to the housing.

[0005] In the aforementioned testing components, production and installation personnel can pre-install multiple branches of the conductive busbar into the corresponding sensors on the circuit board, constructing the conductive busbar and circuit board as a single integrated module. During subsequent production and installation, this integrated module of conductive busbar and circuit board can be directly fixed to the housing. This eliminates the need for repeated alignment of the conductive busbar and sensors within the confined installation space of the power distribution equipment. Firstly, it enables modular installation of the testing components, improving the installation efficiency of the power distribution equipment. Secondly, it reduces the risk of sensor damage due to interference or collision between the conductive busbar and sensors (or other components) during installation. Furthermore, the fixed conductive busbar to the circuit board allows it to function as a handle during handling, preventing accidental contact with components on the circuit board and thus avoiding damage and reduced product yield.

[0006] In some embodiments of this application, the conductive busbar further includes a main support bar, with multiple branch bars fixedly connected to the side of the main support bar along a first direction, and the multiple branch bars arranged along a second direction, the first direction and the second direction intersecting. By setting the main support bar, multiple branch bars can be simultaneously inserted into the corresponding sensors at one time, which is beneficial to improve the assembly efficiency between the conductive busbar and the circuit board.

[0007] In some embodiments of this application, the conductive busbar is provided with a mounting portion located on the main support bar. The conductive busbar is fixedly connected to the circuit board via the mounting portion.

[0008] By placing the mounting section on the main support bar, production and installation personnel no longer need to process multiple branch bars. This not only reduces processing steps and improves the installation efficiency of the testing components, but also helps to improve the structural strength of the branch bars themselves and extend their service life.

[0009] In some embodiments of this application, the conductive busbar is provided with a mounting portion located on the branch strip. The conductive busbar is fixedly connected to the circuit board via the mounting portion.

[0010] By placing the mounting part on the branch bar, the stability of each branch bar fixed to the circuit board can be ensured, reducing the risk of damage to one or more branch bars due to shaking or collision.

[0011] In some embodiments of this application, the conductive busbar is provided with a mounting portion located on the main support bar and branch bars. The conductive busbar is fixedly connected to the circuit board via the mounting portion.

[0012] By placing the mounting part on both the branch bar and the main support bar, double fixation of the busbar can be achieved, which can better improve the stability of the connection between the busbar and the circuit board and reduce the risk of the busbar falling off or shifting.

[0013] In some embodiments of this application, the mounting part is a threaded post, and the circuit board has a threaded hole. The threaded post is configured to connect with the threaded hole when the conductive busbar is fixedly connected to the circuit board. By adopting a threaded connection, the connection between the conductive busbar and the circuit board has high stability and strong connection strength.

[0014] In some embodiments of this application, the mounting part is a snap-fit, the circuit board has a slot, and the snap-fit ​​is configured to snap into the slot when the conductive busbar is fixedly connected to the circuit board.

[0015] By using a snap-fit ​​connection, it is easier to install or remove the busbar from the circuit board, which facilitates the subsequent maintenance or replacement of the testing components. Production and installation personnel only need to disconnect the snap-fit ​​from the slot without damaging the components.

[0016] In some embodiments of this application, the main support bar is fixedly connected to the housing. By fixing the main support bar and the housing, the detection component can be doubly secured, which helps to improve the stability and safety of the detection component installation.

[0017] In some embodiments of this application, the main support bar has a U-shaped structure to enclose and form a receiving area, and the branch bars and sensors are all located within the receiving area.

[0018] The main support bar can protect the branch bars and sensors located within the housing area. During production and installation, it protects the branch bars and sensors from being touched or damaged, thus improving the yield rate. At the same time, since the branch bars and sensors are all within the housing area, where space is limited, insufficient space can lead to misalignment of the branch bars and sensors. This reduces the risk of misalignment during installation and also improves assembly efficiency.

[0019] In some embodiments of this application, the conductive busbar is bonded to the circuit board. This bonding method is not only simple and inexpensive, but also eliminates the need for additional processing of the conductive busbar and circuit board by production and installation personnel, thus improving assembly efficiency between the conductive busbar and the circuit board.

[0020] In some embodiments of this application, the conductive busbar is soldered to the circuit board. Using a soldering connection method improves the stability and reliability of the connection between the conductive busbar and the circuit board, extending the lifespan of the detection component.

[0021] One embodiment of this application provides a power distribution device. The power distribution device includes a housing and a detection component as described in any of the above embodiments. The detection component is fixed to the housing.

[0022] In the aforementioned power distribution equipment, production and installation personnel can pre-install multiple branches of the conductive busbar into the corresponding sensors on the circuit board, constructing the conductive busbar and circuit board as an integrated structure, forming a single module. During subsequent production and installation, the integrated conductive busbar and circuit board module can be directly fixed to the housing. This eliminates the need for repeated alignment of the conductive busbar and sensors within the confined installation space of the power distribution equipment. Firstly, it enables modular installation of the detection components, improving the installation efficiency of the power distribution equipment. Secondly, it reduces the risk of sensor damage due to interference or collision between the conductive busbar and sensors (or other components) during installation. Furthermore, the fixed conductive busbar to the circuit board allows it to act as a handle during transport, preventing accidental contact with components on the circuit board and thus avoiding damage and reduced product yield.

[0034] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0036] Power distribution equipment typically incorporates various detection components to monitor the flow of electricity. These components can be CT sensors, Hall effect sensors, and so on. In related technologies, the assembly of these detection components often requires first assembling the circuit board, then installing the busbar and threading it through the sensor on the circuit board. However, due to the limited installation space within the power distribution equipment, the busbar is prone to colliding with the sensor during its threading, leading to sensor damage. This necessitates constant adjustments to the angle and position of the busbar by production and installation personnel, wasting considerable time.

[0037] One embodiment of this application provides a detection component. The detection component is applied to power distribution equipment, which has a housing. The detection component includes a busbar and a circuit board. The busbar has multiple branches, and the circuit board has multiple sensors, with each branch corresponding to one sensor. The circuit board is configured to be integrally formed with the busbar and fixed to the housing.

[0038] In the aforementioned testing components, production and installation personnel can pre-install multiple branches of the conductive busbar into the corresponding sensors on the circuit board, constructing the conductive busbar and circuit board as a single integrated module. During subsequent production and installation, the integrated module of the conductive busbar and circuit board can be directly fixed to the housing. This eliminates the need for repeated alignment of the conductive busbar and sensors within the confined installation space of the power distribution equipment. Firstly, it enables modular installation of the testing components, improving the installation efficiency of the power distribution equipment. Secondly, it reduces the risk of sensor damage due to interference or collision between the conductive busbar and sensors (or other components) during installation. Furthermore, the fixed conductive busbar to the circuit board allows it to function as a handle during handling, preventing accidental contact with components on the circuit board and thus avoiding damage and reduced product yield.

[0039] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0040] Please refer to the following: Figure 1 and Figure 2One embodiment of this application provides a power distribution device 100. The power distribution device 100 is configured to be electrically connected to an input power source, such as mains power, photovoltaic power, a generator, or an energy storage device. The power distribution device 100 can distribute electrical energy from the input source to corresponding appliances or areas in a user's home.

[0041] In some embodiments, the power distribution equipment 100 includes a housing 20 and a detection component 10, the detection component 10 being fixed to the housing 20. The detection component 10 is used to monitor the flow of electrical energy. The detection component 10 can be a CT sensor, a Hall sensor, etc., and this application does not limit it; those skilled in the art can choose according to the actual situation.

[0042] Please refer to the following: Figure 3 and Figure 4 In some embodiments, the detection component 10 includes a conductive bar 11 and a circuit board 12. The conductive bar 11 has multiple branches 111, and the circuit board 12 has multiple sensors 121, with each branch 111 corresponding to one sensor 121.

[0043] Specifically, branch strips 111 correspond to the power distribution branches of the power distribution equipment 100, used to distribute the electrical energy input by the power distribution equipment 100 to different branches in the user's home. Each branch strip 111 is connected to a sensor 121, which can detect the amount of electricity flowing through each branch for monitoring. Branch strips 111 can be metal components such as copper or aluminum busbars. Multiple branch strips 111 can be directly connected to the main output terminal of the power distribution equipment 100 for power distribution, or they can be connected to the main output terminal of the power distribution equipment 100 through other conductive components. Here, the main output terminal is the terminal where the power distribution equipment 100 receives electrical energy and outputs it to each branch.

[0044] It is worth noting that each branch 111 corresponds to a sensor 121. Specifically, each of the multiple sensors 121 corresponds one-to-one with each of the multiple branch 111, and each branch 111 is connected to a different sensor 121.

[0045] In some embodiments, there may be branches that do not require monitoring of the flow of electricity. In this case, some branches 111 do not need to be fitted with sensors 121, and the circuit board 12 does not need to be fitted with corresponding sensors 121.

[0046] In some embodiments, the circuit board 12 is configured as an integral structure with the busbar 11 and fixed to the housing 20. It should be noted that the above-mentioned integral structure specifically refers to the assembly and connection of the busbar 11 and the circuit board 12 to form a modular component, which can participate in subsequent production and installation as a whole, and does not mean that the two are integrally formed structures.

[0047] This application does not limit the connection method between the conductive busbar 11 and the circuit board 12, and those skilled in the art can choose according to the actual situation.

[0048] Understandably, when assembling the electrical equipment 100, production and installation personnel can pre-install multiple branches 111 of the conductive busbar 11 into the corresponding sensors 121 on the circuit board 12, and construct the conductive busbar 11 and the circuit board 12 into an integrated structure, forming a single module. Subsequently, during production and installation, the production and installation personnel can directly fix the integrated module formed by the conductive busbar 11 and the circuit board 12 onto the housing 20.

[0049] Therefore, subsequent production and installation personnel no longer need to repeatedly align the conductive busbar 11 and sensor 121 within the confined installation space of the power distribution equipment 100. This allows for modular installation of the detection component 10, improving the installation efficiency of the power distribution equipment 100. Furthermore, it reduces the risk of interference or collision between the conductive busbar 11 and the sensor 121 (or other components such as screws or limit posts) during installation, thus minimizing the risk of damage to the sensor 121. In addition, the conductive busbar 11 is fixed to the circuit board 12. During production and installation, the conductive busbar 11 can serve as a handle, preventing personnel from touching the circuit board 12 while handling it. This avoids accidental contact with components on the circuit board 12, preventing damage and reducing the yield rate of product parts.

[0050] It is worth noting that subsequent production and installation personnel use a stacking method when fixing the integrated conductive busbar 11 and circuit board 12 to the housing 20. This helps to better reduce the risk of interference between the integrated conductive busbar 11 and circuit board 12 and other components on the housing 20 when they are installed on the housing 20, thereby improving the safety of the power distribution equipment 100 assembly.

[0051] It should also be noted that production and installation personnel can be from upstream suppliers, parts suppliers, or personnel involved in previous installation steps. Subsequent production and installation personnel can be from downstream suppliers or personnel involved in subsequent installation steps.

[0052] In some embodiments, the circuit board 12 is provided with a first mounting hole 123, and external fasteners (specifically screws, bolts, or other threaded parts) pass through the first mounting hole 123 and are threadedly connected to the housing 20.

[0053] In other embodiments, the circuit board 12 and the housing 20 may also be fixedly connected in other ways. This application does not limit this, and those skilled in the art can choose according to the actual situation.

[0054] Please refer to the following: Figure 4 and Figure 5 In some embodiments, the first direction and the second direction are defined to intersect. The first direction is parallel to the direction indicated by X in the figure, and the second direction is parallel to the direction indicated by Y in the figure. For ease of reference to the figure, the first direction will be referred to as "first direction X" and the second direction as "second direction Y" in the following text.

[0055] The busbar 11 also includes a main support bar 112, with multiple branch bars 111 fixedly connected to the side of the main support bar 112 along a first direction X, and the multiple branch bars 111 arranged along a second direction Y. The main support bar 112 is connected to the main output terminal of the power distribution equipment 100, distributing the input electrical energy to each branch bar 111.

[0056] Multiple branch bars 111 can be connected to the main support bar 112 by welding, screw fixing, or other fixing methods. Alternatively, multiple branch bars 111 can be integrated with the main support bar 112 into a single unit through an integral molding process. By setting the main support bar 112, production and installation personnel can simultaneously thread multiple branch bars 111 into the corresponding sensors 121 at one time, which helps to improve the assembly efficiency between the conductive busbar 11 and the circuit board 12.

[0057] Understandably, when assembling the conductive busbar 11 and the circuit board 12, the production and installation personnel only need to move the main support bar 112 to the target position (specifically, the position of the main support bar 112 when all the branch bars 111 are aligned with their corresponding sensors 121) to insert all the branch bars 111 into their respective sensors 121. In some embodiments, the main support bar 112 can be fixed first, and then the corresponding branch bars 111 can be fixed sequentially; or the corresponding branch bars 111 can be fixed first, and then the main support bar 112 can be fixed.

[0058] Please refer to the following: Figure 6 and Figure 7 In some embodiments, the conductive bus 11 is provided with a mounting part 113, and the conductive bus 11 is fixedly connected to the circuit board 12 through the mounting part 113, so as to assemble the conductive bus 11 and the circuit board 12 into an integrated structure, that is, to realize the modularization of the detection component 10.

[0059] In some embodiments, the mounting part 113 is located on the main support 112. By setting the mounting part 113 on the main support 112, production and installation personnel do not need to process multiple branch bars 111, which not only reduces processing steps and improves the installation efficiency of the detection component 10, but also helps to improve the structural strength of the branch bars 111 themselves and extend their service life.

[0060] For example, when assembling the conductive busbar 11 and the circuit board 12, multiple branch bars 111 are respectively inserted into the corresponding sensors 121 in the circuit board 12, and the main branch bar 112 is fixedly connected to the circuit board 12 through the mounting part 113.

[0061] In some embodiments, the mounting portion 113 is located on the branch bar 111. By providing the mounting portion 113 on the branch bar 111, the stability of each branch bar 111 fixed to the circuit board 12 can be ensured, reducing the risk of damage to one or more branch bars 111 due to shaking or collision.

[0062] For example, when assembling the conductive busbar 11 and the circuit board 12, multiple branch bars 111 are respectively inserted into the corresponding sensors 121 in the circuit board 12 and fixedly connected to the circuit board 12 through the mounting part 113.

[0063] In some embodiments, the mounting portion 113 is located on the main support 112 and the branch bar 111. By providing the mounting portion 113 on the branch bar 111 and the main support 112, the conductive busbar 11 can be double-fixed, which can better improve the stability of the connection between the conductive busbar 11 and the circuit board 12 and reduce the risk of the conductive busbar 11 falling off or shifting.

[0064] For example, when assembling the conductive busbar 11 and the circuit board 12, multiple branch bars 111 are respectively inserted into the corresponding sensors 121 in the circuit board 12 and fixedly connected to the circuit board 12 via the mounting part 113. At the same time, the main branch bar 112 is also fixedly connected to the circuit board 12 via the mounting part 113.

[0065] Please refer to the following: Figure 6 and Figure 7 In some embodiments, the mounting part 113 is a threaded post (not shown), the circuit board 12 is provided with a threaded hole 122, and the threaded post is configured to connect with the threaded hole 122 when the conductive busbar 11 is fixedly connected to the circuit board 12.

[0066] By using a threaded connection, the connection between the conductive busbar 11 and the circuit board 12 has high stability and strong connection strength.

[0067] In some embodiments, the mounting part 113 is a snap-fit ​​(not shown), the circuit board 12 is provided with a slot (not shown), and the snap-fit ​​is configured to snap into the slot when the conductive busbar 11 is fixedly connected to the circuit board 12.

[0068] By using a snap-fit ​​connection, it is convenient to install or remove the conductive busbar 11 from the circuit board 12, and to facilitate the subsequent maintenance or replacement of the detection component 10. Production and installation personnel only need to disconnect the snap-fit ​​from the slot without damaging the component.

[0069] Please refer to the following: Figure 4 , Figure 6 and Figure 7In some embodiments, the main support 112 is fixedly connected to the housing 20. By fixing the main support 112 and the housing 20, the detection component 10 can be doubly fixed (specifically, the circuit board 12 is fixedly connected to the housing 20, and the conductive busbar 11 is fixedly connected to the housing 20), which helps to improve the stability and safety of the installation of the detection component 10.

[0070] In some embodiments, the main support bar 112 is provided with a second mounting hole 114, through which external fasteners (specifically screws, bolts, or other threaded parts) pass and are threadedly connected to the housing 20.

[0071] In other embodiments, the electric bus 11 and the housing 20 may also be fixedly connected in other ways. This application does not limit this, and those skilled in the art can choose according to the actual situation.

[0072] In some embodiments, the main support 112 has a U-shaped structure to enclose and form a receiving area (not shown). The branch bars 112 and the sensor 121 are both located within this receiving area. Specifically, the opposite ends of the main support 112 are bent towards the same side, making the entire main support 112 have a U-shaped configuration. The branch bars 112 and the sensor 121 are arranged within the receiving area enclosed by this U-shaped configuration. Therefore, firstly, the main support 112 can protect the branch bars 111 and the sensor 121 located within the receiving area, preventing them from being easily touched or damaged during production and installation, thus improving the yield rate. Secondly, since the branch bars 112 and the sensor 121 are both within the receiving area, where space is limited, insufficient space prevents misalignment of the branch bars 112 and the sensor 121 during installation, reducing the risk of misalignment and improving assembly efficiency.

[0073] In some embodiments, the conductive busbar 11 is bonded to the circuit board 12. Exemplarily, a production installer applies adhesive (not shown) to the surface of the conductive busbar 11. Subsequently, multiple branch strips 111 are threaded through the corresponding sensors 121 in the circuit board 12 and bonded to the circuit board 12 using adhesive.

[0074] By adopting an adhesive connection method, not only is the operation simple and inexpensive, but also production and installation personnel do not need to perform additional processing on the conductive busbar 11 and the circuit board 12, which helps to improve the assembly efficiency between the conductive busbar 11 and the circuit board 12.

[0075] In some embodiments, the conductive busbar 11 is soldered to the circuit board 12. For example, production and installation personnel first thread multiple branch strips 111 through the corresponding sensors 121 in the circuit board 12. Subsequently, the conductive busbar 11 is soldered to the circuit board 12 using a soldering device (not shown).

[0076] By adopting a welding connection method, it is beneficial to improve the stability and reliability of the connection between the conductive busbar 11 and the circuit board 12, and extend the service life of the detection component 10.

[0077] Please refer to the following: Figure 4 , Figure 6 and Figure 7 In some embodiments, the circuit board 12 is fixedly connected to the housing 20. By fixing the circuit board 12 to the housing 20, the integrated conductive bar 11 and the circuit board 12 can be installed and fixed as a whole, that is, the modular detection assembly 10 can be installed and fixed as a whole, which is beneficial to improve the assembly efficiency of the detection assembly 10.

[0078] Understandably, when assembling the electrical equipment 100, the production and installation personnel pre-install multiple branches 111 in the conductive busbar 11 into the corresponding sensors 121 in the circuit board 12, and construct the conductive busbar 11 and the circuit board 12 into an integrated structure.

[0079] Subsequently, the production and installation personnel connected the circuit board 12 to the housing 20 to fix the integrated conductive bar 11 and the circuit board 12 onto the housing 20, thereby achieving the overall installation and fixation of the detection component 10 onto the housing 20.

[0080] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of this application fall within the scope of this application's disclosure.
