Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of circuit breakers, and in particular to a circuit breaker that is easy to install. Background Technology
[0002] In low-voltage electrical systems, circuit breakers, as commonly used overload and short-circuit protection devices, are widely used in industrial control, power distribution, and civil buildings. With the increasing diversification of electrical installation requirements, the efficiency and accuracy of circuit breaker installation on-site have become crucial factors affecting project quality and schedule control. Especially in environments with compact distribution boxes and dense wiring, the rapid and accurate installation of circuit breakers has become a key concern for users.
[0003] Current circuit breaker designs often prioritize electrical performance and short-circuit protection capabilities, with less emphasis on user-friendliness during installation. Installers typically rely on experience to determine the circuit breaker's orientation and wiring positions. In environments with limited visibility or poor lighting, this can easily lead to incorrect installation or terminal connections, resulting in rework risks and even safety hazards. Furthermore, the lack of clear physical positioning structures or visual aids for some circuit breakers further complicates the process for novice installers.
[0004] In view of this, the inventors specifically designed a circuit breaker that is easy to install, and this invention arises from this. Utility Model Content

[0032] 1. Circuit breaker body; 2. Mounting base; 3. Color identification parts; 31. Raised stripes; 4. Direction indicator arrow; 5. Alignment indicator window; 6. Guide rail groove; 7. Positioning groove; 8. Limiting wing. Detailed Implementation
[0033] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.
[0034] like Figure 1 As shown, this utility model provides a circuit breaker that is easy to install, including a circuit breaker body 1, a mounting base 2, color identification parts 3, direction indicator arrows 4, alignment indicator windows 5, and a guide rail mating structure, among other key structural components.
[0035] The circuit breaker body 1 has a conventional housing structure and internally houses functional components such as electrical contacts and tripping mechanisms. The housing material is preferably injection-molded from flame-retardant polycarbonate. The lower part of the circuit breaker body 1 is detachably mounted to the mounting base 2 via a snap-fit structure or screws. The snap-fit structure preferably uses a plastic hook with a guide bevel and a groove, providing a self-guiding function during installation and ensuring correct orientation and precise positioning during assembly.
[0036] like Figure 2 As shown, the bottom of the mounting base 2 is provided with a guide rail groove 6 structure that matches a standard electrical guide rail (such as a 35mm DIN rail) for quick mounting and dismounting of the circuit breaker. To prevent slippage, limit wings 8 are further provided on both sides of the guide rail groove 6 to limit lateral displacement and enhance stability. The bottom of the circuit breaker body 1 is provided with a positioning groove 7, which cooperates with the pre-positioning protrusion on the mounting base 2.
[0037] like Figure 1As shown, to improve the ease of identification during on-site installation, multiple color-coded markers 3 are provided on the front of the circuit breaker body 1, corresponding to the terminals of the phase wire, neutral wire, and ground wire, respectively. The color-coded markers 3 can be embedded colored plastic blocks or UV printed, and each marker can have raised stripes 31 or letter symbols to enhance visual and tactile identification.
[0038] On the surface of the mounting base 2, there are molded or spray-painted directional indicator arrows 4. The arrows point in the same direction as the mounting rails, allowing installers to quickly determine the correct orientation of the circuit breaker and avoid reverse installation. In addition, alignment marking windows 5 are provided on the lower edges of both sides of the circuit breaker body 1. These windows are made of transparent acrylic material, allowing the positioning lines on the base to be seen during installation, thus achieving initial alignment.
[0039] like Figure 2 As shown, the lower part of the circuit breaker body 1 is provided with a set of groove structures, which are used in conjunction with the pre-positioning protrusions provided on the mounting base 2 to achieve mechanical alignment before the circuit breaker is pressed into the base, simplifying the installation operation process.
[0040] In addition, to ensure a secure and reliable connection between the main body and the base, matching screw holes are provided between the main body and the base. The holes have a countersunk head structure, and the exposed part of the screw is flush with the housing after it is screwed in, so as not to affect the overall aesthetics and the guide rail installation spacing.
[0041] In summary, by setting color markings, directional arrows, marking windows, and cooperating structures, this utility model not only optimizes the structural layout of the circuit breaker but also significantly improves the intuitiveness and accuracy of installation operations, making it suitable for industrial and building electrical distribution systems with high requirements for installation efficiency and reliability.
[0042] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
