Description

Technical Field

[0001] This utility model belongs to the field of equipment protection technology, and specifically relates to a terminal protection structure. Background Technology

[0002] The core function of the terminal blocks in a reactive power compensation device is to connect capacitors to the power system or related equipment, enabling power transmission and signal delivery. It connects capacitors to the power grid, switches, relays, and other components via cables or wires, and is a critical component ensuring the normal operation of the power compensation device. Its design must be adapted to actual current and voltage levels and possess good environmental adaptability, directly affecting the operational safety and stability of the entire device.

Traditional terminal blocks are small in size and exposed, which not only limits their use in certain environments, but also makes them susceptible to damage from impacts, affecting their reliability. 2. Reactive power compensation devices usually require a large number of terminals to work together. However, traditional products have a high proportion of single-specification terminals and redundant large-specification terminals, resulting in a lack of flexibility in wiring configuration and difficulty in adapting to diverse wiring needs.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] like Figure 1 As shown, the terminal protection structure of this embodiment is a composite structure integrating protection, fixing, and wiring functions. It consists of a rectangular main housing 1, a rectangular protective plate 8, a rectangular adapter frame 12, and several terminals. The main housing 1 has an internal cavity for terminal mounting. Adjacent terminals are connected by a detachable snap-fit ​​method, facilitating adjustment of the number and arrangement of terminals according to actual wiring requirements. Several first wiring ports 2 are provided on both the upper and lower surfaces of the main housing 1, serving as channels for wire entry and exit.

[0022] The protective plate 8 is installed at the opening of the main housing 1, forming the first layer of protection for the housing opening; the adapter frame 12 and the protective plate 8 are fixedly connected to the surface of the main housing 1 (such as by welding, bolting, etc.), and the adapter frame 12 is embedded inside the main housing 1. Together with the protective plate 8, they form a double-layer protective structure to achieve all-round protection for the wiring terminals, effectively blocking the intrusion of external dust, moisture, foreign objects, etc., and avoiding short circuits, corrosion and other faults of the wiring terminals due to environmental factors.

[0023] Symmetrically distributed tripods 3 are installed on the inner walls of both sides of the main housing 1. The two ends of the fixing strip 5 are connected to the ends of the symmetrical tripods 3. The surface of the tripods 3 has through holes, through which the protective plate 8 is fixedly connected to the tripods 3 (e.g., by bolts passing through the through holes and locking), ensuring the stability of the connection between the protective plate 8 and the main housing 1. At the same time, a U-shaped opening 4 is provided on the end face of the tripods 3 facing the protective plate 8. This U-shaped opening 4 can generally be used as a positioning structure. For example, a U-shaped block can be correspondingly set on the surface of the protective plate 8 facing the main housing 1. The U-shaped block can play a positioning and limiting role after cooperating with the U-shaped opening 4.

[0024] like Figure 3 As shown, the terminal blocks are divided into upper terminal block 14 and lower terminal block 15, which are assembled by mutual plugging, and combined with... Figure 4 and Figure 5 It can be seen that both the upper terminal 14 and the lower terminal 15 are "L" shaped structures. The upper terminal 14 has a terminal connection port 16 at one end, and the lower terminal 15 has a terminal connection plug 21 at one end. The terminal connection plug 21 is inserted into the terminal connection port 16 to realize the electrical connection and structural fixation of the upper and lower terminals.

[0025] like Figure 2 As shown, a fixing strip 5 is installed on the inner surface of the main housing 1 facing the adapter frame 12, and several evenly distributed fixing buckles 6 are formed on the surface of the fixing strip 5. Combined with... Figure 3 It can be seen that both the upper terminal 14 and the lower terminal 15 are provided with several interfaces 17. The fixing buckle 6 is connected to the interface 17 one by one to realize the positioning and fixing of the terminal in the adapter frame 12, and to prevent the terminal from being displaced due to vibration, external force, etc.

[0026] like Figure 4As shown, adjacent upper terminals 14 employ a detachable snap-fit ​​structure. One side of each upper terminal 14 has a first locking block 18 with a slot 19 at its end, and a second locking block 20 on its opposite side. When multiple upper terminals 14 are installed side-by-side, the second locking block 20 of one terminal can snap into the slot 19 of the first locking block 18 of the adjacent terminal, enabling quick connection and disconnection of adjacent terminals. In actual installation, users can install the required number of terminals as needed, avoiding situations where a single terminal is insufficient.

[0027] Optionally, in Figure 1 The middle protective plate 8 has a protective opening 9, and a protective door 10 is hinged to the surface opposite to the adapter frame 12. A round handle 11 is installed on the surface of the protective door 10, which makes it convenient for operators to inspect and maintain the wiring terminals by opening and closing the protective door 10. When the protective door 10 is closed, it can completely cover the protective opening 9 to ensure the integrity of the protection.

[0028] Optional, Figure 1 The upper and lower surfaces of the intermediate junction box 12 are provided with several second wiring ports 13. The second wiring ports 13 are aligned with the first wiring ports 2 of the main housing 1 to form a through channel for the wires, ensuring that the wires connected to the terminals can pass through smoothly and complete the wiring. Optional, Figure 2 An alarm 7 is also installed on the inner wall of the main housing 1. The alarm 7 is linked with the circuit of the wiring terminal (such as by detecting abnormal temperature or current of the terminal) to provide timely feedback on abnormal working status of the wiring terminal.

[0029] It should be noted that when the above-mentioned protective structure is working normally, the terminals transmit current through the wires. The protective plate 8, the adapter frame 12, and the protective door 10 work together to block external interference, ensuring that the terminals work in a clean and stable environment. The alarm 7 monitors the terminal status in real time and remains silent when there is no abnormality. When maintenance or adjustment of the circuit is required, the operator can open the protective door 10 through the handle 11 to inspect the terminals, adjust the wiring, or add or remove terminals through the protective opening 9. After the operation is completed, the protective door 10 is closed to restore the protective state.

[0030] It should be further explained that if an abnormal situation such as overcurrent or overheating occurs at the wiring terminal, the alarm 7 will be triggered immediately. The operator can quickly open the protective structure through the protective door 10 to troubleshoot and handle the fault, and prevent the fault from escalating.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
