Description

Technical Field

[0001] This utility model relates to the field of power safety equipment, and in particular to an intelligent circuit breaker with a pluggable LSTM module. Background Technology

[0002] A circuit breaker is a switching device that can close, carry, and interrupt current under normal circuit conditions and close, carry, and interrupt current under abnormal circuit conditions within a specified time. In the generation, transmission, and use of electricity, power distribution is an extremely important link. The power distribution system includes transformers and various high and low voltage electrical equipment, and low voltage circuit breakers are a widely used type of electrical appliance.

[0003] Traditional circuit breakers have limited functionality, offering only overload and short-circuit protection and lacking intelligent detection capabilities for electric shock to living beings. Adding leakage current protection or intelligent analysis functions requires replacing the entire circuit breaker, resulting in high costs and waste. Furthermore, their modular design is insufficient, preventing flexible adjustments to protection strategies based on changes in the power grid environment (such as humid or industrial settings). While some circuit breakers on the market have addressed these issues with modular external connection designs, existing modular plug-in structures still suffer from the following technical drawbacks: some modular circuit breakers use non-standardized interfaces, leading to poor module compatibility; additionally, the plug-in mechanism has low reliability, easily causing poor contact or electrical safety hazards. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an intelligent circuit breaker with a pluggable LSTM module.

[0005] This utility model is achieved using the following technical solution: a smart circuit breaker with a pluggable LSTM module, comprising a circuit breaker body and a modular slot disposed on the outside of the circuit breaker body, and a pluggable LSTM module inserted into the modular slot. The inner wall of the modular slot is fixedly connected with two sets of symmetrical metal guide rails. A spring contact is also disposed at the bottom of the inner wall of the modular slot. Locking pin assemblies are also disposed on both sides of the metal guide rails near the bottom of the inner wall of the modular slot. The outer wall of the pluggable LSTM module is provided with a guide groove that locks into the metal guide rails. The outer side of the pluggable LSTM module is also provided with 10-pin gold fingers that fit and contact the spring contact. A positioning assembly that locks into the locking pin assembly is disposed on the inner wall of the bottom guide groove of the pluggable LSTM module.

[0006] As a further improvement to the above solution, a guide rod is fixedly connected to the bottom of the inner wall of the modular slot, and a guide hole that fits onto the outside of the guide rod is fixedly connected to the outer side of the pluggable LSTM module.

[0007] As a further improvement to the above solution, the spring contact is made of beryllium bronze with a gold plating thickness of ≥3μm and a insertion / removal life of ≥10,000 cycles.

[0008] As a further improvement to the above solution, the locking pin assembly includes a storage groove disposed on the outside of the metal guide rail, and a protruding locking pin is fixedly installed in the storage groove. The protruding locking pin is made of elastic plastic material, and the outer surface of the protruding locking pin is designed with an inclined surface structure.

[0009] As a further improvement to the above solution, the positioning component includes a push rod that is movably inserted through and extends into the cavity of the pluggable LSTM module. The inner wall of the guide groove is provided with a slot communicating with the cavity of the pluggable LSTM module. After the pluggable LSTM module is inserted into the modular slot, the slot corresponds to the storage slot, and the protruding pin engages with the slot.

[0010] As a further improvement to the above solution, a handle is fixedly connected to the outer end of the push rod. The handle is connected to the outer wall of the pluggable LSTM module by a spring. The spring is in a spring-extended state by default. The inner end of the push rod is in contact with the inclined surface on the outer side of the protruding locking pin.

[0011] As a further improvement to the above solution, the dimensions of the circuit breaker body are: 180mm×100mm×60mm.

[0012] As a further improvement to the above solution, the dimensions of the modular slot are 35mm × 25mm × 15mm.

[0013] As a further improvement to the above solution, the dimensions of the housing of the pluggable LSTM module are 32mm×22mm×12mm, and the housing of the pluggable LSTM module is made of ABS flame-retardant material.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: The standardized slot design adopted in this utility model supports multiple types of functional modules and builds an ecosystem of "basic circuit breaker body + pluggable LSTM module functional unit". It has obvious compatibility innovation, breaks through the limitation of "complete machine replacement" of traditional circuit breakers, and supports live upgrade of intelligent algorithm modules. This utility model innovates and optimizes the plug-in structure by setting a triple composite interface of "metal guide rail + locking pin assembly + gold finger" to achieve fast and reliable plug-in and plug-out of the module. The module replacement time is ≤1 minute, no power outage debugging is required, and the operation and maintenance cost is significantly reduced. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please combine Figure 1-7 A smart circuit breaker with a pluggable LSTM module includes a circuit breaker body 1 and a modular slot 2 disposed on the outside of the circuit breaker body 1. It also includes a pluggable LSTM module 3 inserted into the modular slot 2. Two sets of symmetrical metal guide rails 4 are fixedly connected to the inner wall of the modular slot 2. A spring contact piece 5 is also provided at the bottom of the inner wall of the modular slot 2. Locking pin assemblies 6 are also provided on both sides of the metal guide rails near the bottom of the inner wall of the modular slot 2. A guide groove 7 is provided on the outer wall of the pluggable LSTM module 3 to engage with the metal guide rails 4. A 10-pin gold finger 8 is also provided on the outer side of the pluggable LSTM module 3 to contact the spring contact piece 5. The pluggable LSTM module 3 is located in the bottom guide groove. A positioning component 9 is provided on the inner wall of the guide groove 7, which is engaged with the locking pin assembly 6. It should also be noted that the locking pin assembly 6 includes a storage groove 601 located on the outside of the metal guide rail 4, and a protruding locking pin 602 is fixedly installed in the storage groove 601. The protruding locking pin 602 is made of elastic plastic and has an inclined surface structure design on its outer side. The positioning component 9 includes a push rod 901 that is movably inserted and extends into the inner cavity of the pluggable LSTM module 3. The inner wall of the guide groove 7 is provided with a slot 902 that communicates with the inner cavity of the pluggable LSTM module 3. After the pluggable LSTM module 3 is inserted into the modular slot 2, the slot 902 corresponds to the storage groove 601, and the protruding locking pin 602 and the slot 902 are engaged.

[0022] Based on the above structural configuration, during the insertion and installation of the pluggable LSTM module 3, the operator mates the pluggable LSTM module 3 into the modular slot 2 on the outside of the circuit breaker body 1, and the guide groove 7 on the outside of the pluggable LSTM module 3 mates with the metal guide rail 4 on the inner wall of the modular slot 2. Then, the pluggable LSTM module 3 is inserted laterally. During the inward insertion of the pluggable LSTM module 3, the outer surface of the pluggable LSTM module 3 will touch the inclined surface on the outside of the protruding locking pin 602. (Refer to the attached instruction manual.) Figure 5 As the pluggable LSTM module 3 continues to be inserted, it will abut against the protruding latch 602 and be stored in the storage slot 601 on the outside of the metal guide rail 4 until the pluggable LSTM module 3 is fully inserted. At this time, the storage slot 601 aligns with the slot 902 on the outside of the pluggable LSTM module 3, and the protruding latch 602 inside pops out under the elastic force of its own elastic plastic material and snaps into the slot 902 to complete the quick snap-fit ​​installation of the pluggable LSTM module 3. At this time, the 10-pin gold fingers 8 on the outside of the pluggable LSTM module 3 abut against the spring contact 5 in the modular slot 2 and connect to the circuit (supplementary note: after installation and locking, the contact resistance of the pluggable LSTM module 3 under vibration environment is ≤50mΩ, which complies with GB / T 14048.2-2020 standard).

[0023] Based on this, it should be added that after the pluggable LSTM module 3 is pushed horizontally into the modular slot 2 along the metal guide rail 4, a "click" sound will be heard. At this time, it indicates that the locking pin assembly 6 and the positioning assembly 9 are locked in place. At the same time, an indicator light 10 can be set on the outside of the circuit breaker body 1. When the locking is completed and the circuit is connected, the indicator light 10 will light up green.

[0024] Based on this, it should be added that a handle 903 is fixedly connected to the outer end of the push rod 901. The handle 903 is connected to the outer wall of the pluggable LSTM module 3 via a spring 904. The spring 904 is in a spring-extended state by default, and the inner end of the push rod 901 makes contact with the inclined surface on the outer side of the protruding latch 602. Based on this structure, when the pluggable LSTM module 3 needs to be disassembled, the operator needs to use the handle 903 on the outer side of the pluggable LSTM module 3 to push the push rod 901 horizontally and simultaneously compress the spring 904. During the movement, the push rod 901 will contact the inclined surface at the upper end of the protruding latch 602, thereby causing the protruding latch 602 to tilt and disengage from the latch 902. (Refer to the attached instruction manual.) Figure 7 At this point, the pluggable LSTM module 3 can be pulled outward to disengage it from the modular slot 2.

[0025] Here, it should be added that: The inner side of the protruding latch 602 is actually designed with a slight inclination. Because the slot 902 itself has a certain width, in the above embodiment, when the push rod 901 contacts the inclination surface at the upper end of the protruding latch 602 and pushes the protruding latch 602 outward, a small part of the protruding latch 602 is still in the slot 902. When the pluggable LSTM module 3 is pulled outward, the pluggable LSTM module 3 also contacts the slight inclination surface on the inner side of the protruding latch 602. As the pluggable LSTM module 3 continues to be pulled outward, it will continue to squeeze and cause the protruding latch 602 to tilt and bend and completely disengage from the slot 902, ensuring the quick disassembly of the pluggable LSTM module 3. The outer side of the pluggable LSTM module 3 is also magnetically attached with a protective cap 905, which is fitted onto the outside of the handle 903 to prevent accidental contact when the handle 903 is not in use.

[0026] The bottom of the inner wall of the modular slot 2 is also fixedly connected to a guide rod 201, while the outer side of the pluggable LSTM module 3 is fixedly connected to a guide hole 301 that fits onto the outside of the guide rod 201. During the process of plugging the pluggable LSTM module 3 into the modular slot 2, the guide hole 301, together with the guide rod 201, can also play an auxiliary positioning and guiding role. Moreover, the contact surface of the two is designed with a smooth surface structure, which can reduce the sliding resistance and facilitate its smooth sliding.

[0027] It should be added that the spring contact 5 is made of beryllium bronze with a gold plating thickness of ≥3μm and a insertion / removal life of ≥10,000 cycles. The dimensions of the circuit breaker body 1 are 180mm×100mm×60mm; the dimensions of the modular slot 2 are 35mm×25mm×15mm; and the dimensions of the housing of the pluggable LSTM module 3 are 32mm×22mm×12mm. The housing of the pluggable LSTM module 3 is made of ABS flame-retardant material.

[0028] In addition, it is necessary to add the working logic of the pluggable LSTM module 3: (1) The residual current of the circuit breaker body is sampled and then input to the gold finger module after being filtered by anti-aliasing; (2) The module's built-in STM chip calculates the LSTM inference results (formula), and outputs a high level to the main body tripping circuit when an electric shock occurs; (3) The main body reads the module status (such as temperature and model version number) through the SPI interface.

[0029] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.

[0030] In the description of this utility model, it should be understood that the terms indicating orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
