Description

Technical Field

[0001] This utility model belongs to the field of power control, and in particular relates to a power outage auxiliary device for power cost control. Background Technology

[0002] With the rapid development of smart grid technology, power line carrier communication (PLC), as an efficient and convenient communication method, has been widely applied in fields such as smart meters, load management, and remote control. PLC transmits signals through existing power line networks, eliminating the need for additional communication lines and offering advantages such as low deployment costs and wide coverage. However, in practical applications, the stability and reliability of communication signals remain challenging due to various factors affecting power line channels.

[0003] In power outage auxiliary equipment for power cost control, terminal blocks are typically used to connect power equipment to communication modules. Because power lines themselves transmit high-frequency signals, electromagnetic coupling and interference between terminal blocks can cause signal crosstalk, leading to degraded power line carrier communication quality or even communication interruption. This problem is particularly severe in designs with densely packed terminal blocks, affecting the overall performance of the system.

[0004] Based on the above problems, this invention proposes an innovative power outage auxiliary device for controlling electricity costs. Utility Model Content

[0005] The purpose of this invention is to provide an auxiliary device for power outage control to control power costs, thereby improving the stability of power line carrier communication.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] A power outage auxiliary device for controlling electricity costs, the device comprising an upper housing and a lower housing, the upper housing being provided with a display screen for displaying electricity meter data;

[0008] A junction box is provided below the lower housing. The junction box has a wiring groove inside. Multiple independent terminal mounting slots are provided on the wiring groove. The terminal mounting slot has an internal channel near the inside of the device and an external channel near the outside of the device. Two terminals are provided in the terminal mounting slot.

[0009] Beneficial effects:

[0010] This invention reduces signal interference by arranging the wiring terminals separately, and ensures operational safety under high-voltage conditions by using sealed insulating blocks. This greatly improves the communication stability and safety of the equipment. While meeting the requirements of power line carrier communication, the equipment can effectively reduce electromagnetic interference and potential safety hazards, and has important practical application value.

[0011] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0019] This utility model discloses an auxiliary device for power outage control based on electricity costs, used to assist in controlling power outages and restorations based on electricity costs. This device can be a terminal device such as an electricity meter or distribution box. The auxiliary device uses power line carrier communication to transmit signals through the existing power line network. Since power lines themselves transmit high-frequency signals, electromagnetic coupling and interference between terminals may cause signal crosstalk, leading to a decrease in the communication quality of the power line carrier communication or even communication interruption. In this embodiment, the device is an electricity meter that can be remotely controlled for power outages. The device includes an upper housing 1 and a lower housing 2, which are connected and installed together using glue or screws. The upper housing 1 is equipped with a display screen 11 for displaying electricity meter data.

[0020] A junction box 3 is provided below the lower housing 2. The junction box 3 has a wiring groove inside, and multiple independent terminal mounting slots 31 are provided on the wiring groove. The terminal mounting slot 31 has an internal channel 34 near the inside of the device, and an external channel 33 near the outside of the device. The internal channel 34 and the external channel 33 are used for the connection of wires inside the device and wires outside the device, respectively.

[0021] The terminal mounting slot 31 is provided with two-end terminals 5. Wires inserted into the terminal mounting slot 31 from the internal channel 34 and the external channel 33 are interconnected by connecting to the two ends of the terminals 5. An isolation layer 35 is provided between two adjacent terminal mounting slots 31. Through this design, multiple independent terminal mounting slots 31 in the junction box 3 are separated by the isolation layer 35, effectively reducing electromagnetic coupling and signal crosstalk, and improving the stability and communication quality of power line carrier communication. Furthermore, the terminal mounting slots are respectively provided with internal and external channels for independent access of internal and external wires, avoiding wire crossing and improving the clarity of wiring and the convenience of equipment maintenance.

[0022] The wiring trough is provided with a load wiring trough 32, and the access wire of the load wiring trough 32 is connected through the load through hole 37.

[0023] The lower housing 2 and the junction box 3 are integrally injection molded from insulating plastic, which ensures strength and saves costs.

[0024] In some embodiments, a sealing cover plate 4 is provided on the terminal mounting slot 31. The sealing cover plate 4 is installed by a snap-fit ​​method. This design enables quick installation and removal while ensuring a sealing effect, effectively preventing external contaminants such as dust and moisture from entering the terminal slot, thereby improving the working stability and service life of the equipment.

[0025] In some embodiments, a dustproof insulating plate 6 is provided between the terminal mounting groove 31 and the sealing cover plate 4. The dustproof insulating plate 6 includes a center line portion 61, and inclined elastic side plates 62 are provided on both sides of the center line portion 61. During use, the elastic side plates 62 abut against the sides of the wiring groove to complete the seal and provide insulation. The dustproof insulating plate 6 is made of elastic plastic; this design enhances the insulation performance. The elastic side plates 62 of the dustproof insulating plate 6 achieve a seal by abutting against the sides of the wiring groove, effectively isolating the influence of the external environment on the internal circuitry. Furthermore, the center line portion 61 is provided with a handle 64 for convenient installation and disassembly. This design provides additional gripping points, making installation and maintenance more convenient and reducing the difficulty of operation.

[0026] In some embodiments, the wiring groove is provided with multiple positioning plates 36, and the elastic side plate 62 is provided with multiple positioning grooves 63 that cooperate with the positioning plates 36. Thus, when the dustproof insulation plate 6 is installed, the positioning plates 36 are located within the positioning grooves 63. This design ensures accurate positioning and stable installation of the dustproof insulation plate 6 by inserting the positioning plates 36 into the positioning grooves 63. This structural design prevents the dustproof insulation plate 6 from moving or shifting, improving the reliability of the equipment.
