Abstract
Description
Technical Field
[0001] This application relates to the field of feeder terminal technology, and in particular to a modular integrated pole-mounted feeder terminal. Background Technology
[0002] Currently, pole-mounted circuit breaker feeder terminals on the market are available in two types: enclosure-type and box-type. Enclosure-type feeder terminals have more integrated wiring compared to box-type feeder terminals, but they require an external power supply (battery), which increases their size and weight. The larger size and weight not only increase material costs but also make installation and transportation inconvenient. Secondly, the external battery needs to be connected to the feeder terminal body via a cable, which poses a risk of damage. Furthermore, the external battery requires separate consideration for protection and heat dissipation. Finally, enclosure-type FTUs and external batteries produced by different manufacturers may differ in electrical parameters and interface types, which may lead to compatibility issues when used together, affecting the overall performance and stability of the system.
[0003] Although box-type feeder terminals have built-in batteries, their modules have a low degree of integration, resulting in a relatively large overall size and weight. The complex internal wiring also increases the likelihood of malfunctions. Furthermore, troubleshooting becomes particularly cumbersome when a fault occurs. Summary of the Invention
[0004] The purpose of this application is to provide a modular integrated pole-mounted feeder terminal to solve the problem of complex internal wiring in existing box-type feeder terminals.
[0005] To solve the above-mentioned technical problems, this application adopts the following technical solution:

A plug-in circuit board is inserted into the backplane circuit board. A panel is provided on the side of the plug-in circuit board opposite to the backplane circuit board. Terminals are provided on the panel.
[0009] The power supply is located inside the feeder terminal box and supplies power to the controller through the terminals.
[0010] This solution uses a plug-in circuit board mounted on the backplane circuit board, employing a wiring-free connection method, thus avoiding the problems of independent modules and complex internal wiring in existing box-type feeder terminals.
[0011] In this solution, the feeder terminal enclosure serves as a protective shell, internally integrating the controller and power supply. The controller connects to the backplane circuit board via a plug-in board, enabling signal and data transmission from the various functional modules on the plug-in board through the backplane circuit board.

Furthermore, the plug-in board integrates all functional modules, resulting in a compact design that reduces the size and weight of the feeder terminal. In addition, this solution uses terminals as interfaces between the controller and external devices or lines, enabling electrical connections and data exchange between the controller and other devices, increasing the level of integration.

This connector, as a connector, possesses multiple characteristics such as waterproofing, dustproofing, and shock resistance. These characteristics enable the aviation connector to maintain stable connection performance in harsh outdoor environments, ensuring uninterrupted signal and power transmission between the feeder terminal and other devices.
[0022] Optionally, the power source is a storage battery.

Meanwhile, the guide rail 150 can also withstand the impact during the insertion process to a certain extent, protecting the connector 131 and the socket 121 from damage.
[0034] In this embodiment, the plug-in circuit board 130 comprises multiple circuit boards implementing specific functional modules.

This helps reduce circuit damage caused by voltage instability and extends the service life of the terminal. This embodiment improves the filtering effect, energy storage capacity, and voltage stability of the power supply 200 through the capacitor 300. It not only enhances the anti-interference capability of the feeder terminal, but also improves its adaptability and reliability in harsh environments.

To ensure the continuous and stable operation of the feeder terminal, a power charging module 500 connected to the storage battery is installed inside the feeder terminal housing. The power charging module 500 is model HXP22010A-2. The power charging module 500 converts the externally input power 200 into a voltage and current suitable for charging the battery through a charging interface connected to the battery. When the feeder terminal is in operation, the power charging module 500 monitors the battery's charge level in real time and charges it as needed. This not only ensures that the battery always maintains sufficient charge but also extends its service life and improves the overall reliability of the feeder terminal.
