[0044] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0045] like Figure 1 and Figure 2 As shown, this application provides a covered power distribution automation feeder terminal, including a housing 1, a bus circuit board 2, a mounting bracket 3, an input / output circuit board 4, and a power supply assembly 5. The housing 1 includes a base 11 and a cover 12, which together form a first accommodating cavity for accommodating the main functional modules of the terminal. The inner wall of the base 11 is provided with multiple electrical connection sockets, including a backup power connector, a power voltage connector, an open-circuit current resistant connector, a control signal connector, and an Ethernet connector, to realize the electrical connection between external devices and the terminal. One side of the bus circuit board 2 is a mating surface, and the other side is a component surface. Figure 3 and Figure 4As shown, the mating surface is equipped with an electrical connection plug that matches the electrical connection socket 111 of the base 11, enabling quick assembly via plug-in connection. The component surface integrates electronic components such as current transformers, rotary switches, LCD displays, indicator lights, buttons, RJ45 interfaces, DB9 interfaces, toggle switches, pressure plates, and Hall sensors, forming the core functional unit. Except for the aviation connector, components such as current transformers, rotary switches, LCD displays, indicator lights, buttons, RJ45 interfaces, DB9 interfaces, toggle switches, pressure plates, and Hall sensors are all connected to the circuit board using solder plates to optimize component layout space and reduce flying wires. When the bus circuit board 2 is mated with the base 11, the bus circuit board 2 can be directly snapped onto the base 11 to reduce installation workload. The mounting bracket 3 adopts a three-dimensional frame structure spanning above the bus circuit board 2, including a base plate portion 31 and a vertical plate portion 32. The vertical plate portion 32 is vertically fixed to the inner wall of the base 11, and the base plate portion 31 extends perpendicularly to the vertical plate portion 32, forming a stable support structure. The input / output circuit board 4 is fixed to the mounting bracket 3, and together with the mounting bracket 3, they form a second accommodating cavity. The power supply assembly 5 is installed inside the second accommodating cavity and fixed to the inner sidewall of the base plate 31, achieving modular assembly through layered arrangement. This structure improves the utilization of internal space and makes the overall terminal structure more compact and reasonable through the direct plug-in connection of electrical connectors and sockets, the three-dimensional support of the mounting bracket, and the layered accommodating layout of the input / output circuit board and the power supply assembly.

[0046] like Figure 1 and Figure 2 As shown, in a specific embodiment of this application, the input / output circuit board 4 is arranged in parallel with the substrate 31 and is mounted on the mounting bracket 3 via a mechanical connection structure. A stable connection is then formed between the circuit board 4 and the substrate 31 using fasteners. This ensures electrical isolation between the circuit boards and optimizes the internal space layout. The mounting bracket 3 serves as a support structure; its substrate 31 provides a reliable mounting reference surface for the input / output circuit board 4, while the upright plate 32 maintains a reasonable distance between the input / output circuit board 4 and the inner wall of the housing 1. This not only facilitates the installation and positioning of the input / output circuit board 4 but also provides good heat dissipation space for the electronic components on it, while ensuring that the wiring distance with other functional modules complies with electrical safety regulations. This parallel mounting method achieves stable fixation of the input / output circuit board 4 within a limited space, effectively improving the compactness and reliability of the overall structure.

[0047] like Figure 1 and Figure 2As shown in one specific embodiment of this application, a hook 33 is provided on the upright plate 32 of the mounting bracket 3. The hook 33 is integrally formed with the upright plate 32 by stamping, forming a cantilever structure with a specific angle. A mounting hole 41 is correspondingly provided on the edge of the input / output circuit board 4, the diameter of which matches the cross-sectional size of the hook 33. When the input / output circuit board 4 is installed onto the mounting bracket 3, the mounting hole 41 slides into the guide slope of the hook 33 and finally engages and fixes, achieving rapid positioning and reliable connection.

[0048] like Figure 1 and Figure 2 As shown in a specific embodiment of this application, the mounting hole 41 adopts a stepped structure design, comprising two functional areas: a mating portion and a plug-in portion. The mating portion has a larger hole diameter, facilitating accurate alignment of the hook portion 33 during assembly; the hole diameter of the plug-in portion closely matches the cross-sectional dimensions of the hook portion 33, ensuring the structural stability of the input / output circuit board 4 after mounting. During assembly, the hook portion 33 first enters the mounting hole 41 guided by the mating portion, and then moves axially to the plug-in portion for final positioning. This two-stage hole structure design reduces assembly accuracy requirements while ensuring final connection strength, effectively solving the technological challenges of precision assembly in confined spaces.

[0049] like Figure 1 As shown, in one specific embodiment of this application, the mating surface of the bus circuit board 2 is further provided with a mounting panel 6, which is fixedly connected to the bus circuit board 2 by fasteners. The mounting panel 6 is made of stamped metal sheet and has multiple standardized mounting holes, including circular mounting holes, rectangular mounting holes, and irregularly shaped mounting holes. Operating components such as the LCD display, operation buttons, status indicator lights, and function switches are installed in the mounting holes according to a preset layout, realizing the integrated arrangement of the human-machine interface.

[0050] like Figure 1 As shown, in one specific embodiment of this application, a power switching component 7 is included, which is mounted on the mounting bracket 3. The power switching component 7 is used to realize reliable switching between the internal power supply and the external power supply of the bus circuit board 2.

[0051] like Figure 1As shown in a specific embodiment of this application, the power switching component 7 includes a backup power battery 71 and a die-cutting circuit board 72. The backup power battery 71 is mounted on the mounting bracket 3, and the die-cutting circuit board 72 is mounted on the outer wall of the base plate 31. The input terminal of the die-cutting circuit board 72 is electrically connected to the output terminal of the backup power battery 71 and the DC output terminal of the power component 5 through a dual power input interface, respectively. Its output terminal is connected to the power input port of the bus circuit board 2 through a multi-core ribbon cable. The die-cutting circuit board 72 integrates a voltage detection circuit, a switching control circuit, and a power filtering circuit. When an abnormality is detected in the main power supply, it can automatically switch to the backup power supply, which not only ensures the reliability of power switching but also makes full use of the structural space of the mounting bracket 3, realizing a compact layout of the power distribution terminal power system.

[0052] like Figure 1 As shown, in one specific embodiment of this application, a traveling wave ranging component 8 is included, mounted on the outer wall of the base plate 31. This component enables bidirectional signal transmission with the bus circuit board 2 via a standard communication interface. The traveling wave ranging component 8 includes a high-frequency signal acquisition module, a time measurement unit, and a data processing unit. The high-frequency signal acquisition module can accurately capture the traveling wave signal of a line fault. The time measurement unit is used to ensure accurate measurement of the traveling wave propagation time. The data processing unit interacts with the bus circuit board 2 via RS485 or CAN bus to achieve real-time transmission of fault location information.

[0053] like Figure 1 As shown in a specific embodiment of this application, a suction cup antenna 9 is fixedly mounted on the mounting bracket 3. This antenna is connected to the wireless communication module of the bus circuit board 2 via a coaxial cable. The suction cup antenna 9 operates in the 400MHz-2.4GHz frequency band and supports multiple wireless communication standards such as GPRS / 3G / 4G. The antenna feed line is led to the bus circuit board 2 through a pre-set wiring channel in the mounting bracket 3. The connection point uses an SMA-type RF connector to ensure signal transmission quality. This not only ensures the optimal radiation performance of the antenna but also achieves a stable connection between the antenna and the terminal body through the bracket structure, effectively solving the problem of traditional external antennas being prone to loosening and falling off.

[0054] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
