Description

Technical Field

[0001] This utility model relates to the field of circuit breaker technology, specifically to a digital display time circuit breaker. Background Technology

[0002] Circuit breakers are a crucial basic electrical component. Their core function is to automatically cut off current when faults such as short circuits and overloads occur in a circuit, providing safety for power systems and electrical equipment. With the rapid development of industrial automation, intelligent buildings, and energy-saving management, higher requirements are placed on the control functions of circuit breakers. Traditional circuit breakers with only protection functions are no longer sufficient to meet the needs of complex application scenarios.

[0003] Digital display timer circuit breakers have emerged as a result. They are intelligent upgrades that deeply integrate microelectronics, sensing, and digital display technologies, building upon the traditional safety protection functions of circuit breakers. These products typically consist of a circuit breaker body combined with a digital display countdown trip module that integrates a control chip, timing circuit, and digital display screen. They not only retain overload and short-circuit protection functions but also add two major advantages: programmable timing control and intuitive visualization of operating status. Users can precisely set the power-on duration through its digital interface. The device automatically analyzes and cuts off power after the countdown ends, thus achieving automated circuit management, energy saving, and safe operation. They are widely used in charging equipment, industrial equipment, advertising lighting, and other fields requiring timing control.

[0004] However, prior to this invention, existing digital display time circuit breakers had significant shortcomings in their structural design, particularly in the mechanical connection between the two modules. The mainstream fixing method relied on screw fastening. While this connection method was robust and reliable, its drawbacks were also quite prominent:

[0005] 1. Cumbersome and inefficient installation: Installers must use external tools (such as screwdrivers) to operate, which increases the number of steps and reduces assembly efficiency. This is especially true in cases where batch installation is required, where the time and effort involved are particularly significant.

[0006] 2. Inconvenient maintenance: When it is necessary to inspect, replace or upgrade the digital display trip unit or circuit breaker separately, the disassembly process is also cumbersome and cannot be quickly separated, which increases maintenance time and labor costs.

[0007] 3. Poor user experience: For end users, the screw installation method is not user-friendly and has a high operating threshold, making it impossible to achieve an easy and quick plug-and-play experience, which to some extent affects the product's market acceptance and application flexibility.

[0008] Therefore, there is an urgent need in this field for a new type of connection structure to solve the many problems caused by the above-mentioned screw fixing method, so as to achieve the goal of reliable connection between digital countdown trip unit and circuit breaker, and quick installation and disassembly, thereby improving the overall competitiveness of the product and user experience. Utility Model Content

[0009] The present invention provides a digital display time circuit breaker to solve the problems mentioned in the background art.

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] A digital display timed circuit breaker includes a circuit breaker and a digital display countdown trip unit that are used together. The circuit breaker has a laterally rotatable connecting plate at its top and bottom front side, and a locking block at the free end of the connecting plate. The digital display countdown trip unit has a locking groove extending outward from its top and bottom front side, which mates with the locking block. A sliding rod is provided on both sides of the locking groove. A baffle for restricting the locking block within the locking groove is slidably mounted on the sliding rod. A spring is sleeved on the sliding rod, and one end of the spring acts on the baffle to provide an elastic force that moves the baffle toward the locking groove.

[0012] Preferably, the connecting plate and the card block together form a T-shaped structure.

[0013] Preferably, the end of the baffle away from the slot is provided with a push block.

[0014] Preferably, the connecting plate is rotatably connected to the circuit breaker via a hinge.

[0015] Preferably, the baffle is provided with a sliding hole that matches the sliding rod.

[0016] Preferably, the spring is a compression spring, with its two ends abutting against the ends of the baffle and the slide rod, respectively.

[0017] Beneficial effects

[0018] The digital display timer circuit breaker described in this utility model brings significant benefits through its innovative snap-fit ​​connection structure:

[0019] First, by utilizing a laterally rotating connecting plate in conjunction with a spring-loaded self-locking baffle, the circuit breaker and digital display trip unit can be quickly connected and disconnected, completely eliminating the traditional screw fastening method. Installation requires no tools, greatly improving efficiency and saving time and effort. Second, the spring-driven baffle automatically and reliably locks the locking block in the slot, ensuring a secure connection and good contact, preventing accidental loosening due to vibration or other reasons during use, maintaining safety comparable to traditional methods. Finally, the added push block makes disassembly equally simple; a single push unlocks the device, greatly facilitating future maintenance, replacement, or upgrades. The overall structure is simple and compact, with controllable costs, significantly improving the user experience and market competitiveness of the product. Attached Figure Description

[0029] To avoid excessive and unnecessary details, well-known structures or functions will not be described in detail in the following embodiments.

[0030] like Figure 1-4 As shown, it is a structural schematic diagram of a digital display timer circuit breaker according to a preferred embodiment of the present invention.

[0031] This embodiment provides a digital display timer circuit breaker, which is mainly composed of two major modules, circuit breaker 1 and digital display countdown trip unit 2, which are spliced ​​together by mechanical snap-fit.

[0032] Specifically, at the top and bottom of the front side of the circuit breaker 1, a laterally rotatable connecting plate 3 is hinged via a pivot. The connecting plate 3 can rotate outward around the hinge point by a certain angle (e.g., 90 degrees). The free end of the connecting plate 3 is provided with an integrally formed locking block 4, which together with the connecting plate 3 forms a T-shaped locking tongue structure.

[0033] At the top and bottom positions of the front side of the digital countdown release device 2, a slot 5 extending outwards is provided, matching the shape of the T-shaped locking block 4. Two sliding rods 6 are fixedly installed parallel to each other on both sides of the slot 5. The baffle 7 passes through sliding holes on both sides that match the sliding rods 6, and can slide along the axial direction of the sliding rods 6.

[0034] Each slide rod 6 is fitted with a spring 8. In this embodiment, the spring 8 is preferably a compression spring. Its two ends abut against the inner side of the baffle 7 and the limiting block fixed to the end of the slide rod 6, respectively, thereby providing the baffle 7 with a continuous elastic pressure toward the slot 5, so that it is always in the "closed" or "locked" position.

[0035] On the outer side wall of the end of the baffle 7 facing away from the entrance of the slot 5, there is also a protruding push block 9, which is used to facilitate the manual application of external force to overcome the spring force and push the baffle 7 to slide.

[0036] Installation process: During installation, first push the push block 9 to move the baffle 7 away from the slot 5. Then, align the circuit breaker 1 with the installation position of the digital display trip unit 2. Next, rotate the top and bottom connecting plate 3 towards the slot 5 of the digital display trip unit 2 to open it, so that the locking block 4 on it is inserted into the slot 5. At this time, release the push block 9 so that the baffle 7 quickly returns to its original position under the action of the spring 8 and slides forward, horizontally blocking the top of the locking block 4 like a latch, thereby reliably locking it in the slot 5, completing the quick installation.

[0037] Disassembly process: When disassembly is required, simply push the push blocks 9 on both baffles 7 simultaneously with your fingers to drive the baffles 7 to slide backward against the spring force, thereby releasing the lateral restriction on the locking block 4. At this time, the connecting plate 3 can be pried open outward, thus easily separating the digital display trip unit 2 from the circuit breaker 1.

[0038] This invention, through the ingenious snap-fit ​​and elastic latch structure, enables quick and easy installation and disassembly of two functional modules, while ensuring mechanical reliability after connection, greatly improving product installation and maintenance efficiency and user experience.

[0039] The present invention relates to a digital display time circuit breaker, the installation method, connection method or setting method of which are all common mechanical methods, and any method that can achieve its beneficial effect can be implemented.

[0040] All technologies not described in detail in this utility model are known technologies. Those skilled in the art can easily implement this utility model based on their understanding of this specification, and the contents shown in the accompanying drawings are part of this specification.

[0041] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
