[0002] Insulating plugs are electrical components primarily used to provide excellent insulation performance, preventing current leakage and short circuits. They play a crucial role in various electrical equipment, such as switchgear, distribution boxes, cable joints, and motors, providing strong protection for the safe and stable operation of the equipment. For example, at cable joints, insulating plugs provide good insulation, preventing moisture and dust from entering the joint and ensuring its normal operation. Despite their vital role in electrical equipment, existing technology still has some shortcomings. Traditional insulating plugs typically lack self-testing functions and cannot monitor the insulation status of electrical equipment in real time, potentially leading to delayed detection and handling of electrical faults. Furthermore, existing insulating plugs are standardized in size, while cables vary in thickness, requiring operators to purchase different sized plugs based on cable diameter, significantly increasing costs.

[0016] 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 protection scope of the present utility model.

[0017] Please see Figures 1-4This utility model provides a technical solution including a plug 1, with a slot 2 threaded onto the top of the plug 1, and a hole 3 connected to the bottom of the inner wall of the slot 2. A storage cavity 10 is formed inside the plug 1, and a discharge detection unit 100 is connected inside the storage cavity 10. The discharge detection unit 100 includes a sensor 101, a signal processing circuit 102, a microprocessor 103, a communication module 104, and an indicator / alarm module 105. A power module 106 is connected to the bottom of the storage cavity 10. A connecting ring 4 is threaded onto the surface of the plug 1, and an expansion mechanism 41 is rotatably mounted on the surface of the connecting ring 4. The function of this mechanism is to enable the sensor 101 to monitor key parameters during the discharge process in real time, such as current and voltage, ensuring the real-time performance and accuracy of the data. The high-precision sensor and signal processing... The circuit can improve the accuracy of detection and reduce the probability of false alarms and missed alarms. The signal processing circuit 102 filters and amplifies the signal output by the sensor to improve the reliability and stability of the signal. The microprocessor 103 can further analyze and judge the processed signal and realize intelligent decision-making and early warning based on preset thresholds and algorithms. The communication module 104 enables communication between the discharge detection unit and the remote monitoring system, and uploads real-time monitoring data and analysis results to the remote server in real time. This allows maintenance personnel to grasp the discharge status anytime and anywhere, respond to and handle abnormal situations in a timely manner, and improve maintenance efficiency and safety. Through the indicator alarm module 105, maintenance personnel can quickly locate the fault point and take corresponding measures to repair it, so as to avoid the fault from expanding and the loss from aggravating.

[0018] The inner wall of the hole 3 is provided with a thread 31. The function of the thread 31 is to enable the hole 3 and the power interface to form a tight threaded connection. Compared with the smooth connection without threads, this connection method has higher tensile strength and torsional strength, and can effectively prevent the connection from loosening or falling off due to external forces such as vibration and impact.

[0019] The expansion mechanism 41 includes a rotating plate 411 rotatably mounted on the surface of the connecting ring 4. A transmission plate 412 is rotatably mounted on one end of the rotating plate 411, and an expansion plate 413 is rotatably mounted on one end of the transmission plate 412. A compression spring 414 is connected to one side of the expansion plate 413, and the other end of the compression spring 414 is connected to the surface of the connecting ring 4. Its function is that the expansion mechanism 41 allows for a certain degree of deformation and expansion, so it can adapt to connecting parts of different sizes and shapes. This flexibility allows the insulating plug to be widely used in various electrical connection scenarios, improving its versatility and practicality.

[0020] The signal processing circuit 102, microprocessor 103, communication module 104 and indicator alarm module 105 are all connected to the power output terminal of the power module 106. Their function is to ensure that the entire system receives a stable and consistent power supply by connecting the power input terminals of the signal processing circuit, microprocessor, communication module and indicator alarm module to the output terminal of the power module. This helps to reduce system failures or performance degradation caused by power fluctuations or instability.

[0021] A baffle plate 6 is connected to one end of the plug 1, and the plug 1 and the baffle plate 6 are integrally formed. Its function is to ensure that there are no seams or connection points between the plug 1 and the baffle plate 6, thereby avoiding structural weaknesses caused by improper connection, enhancing the overall structural strength, making it more resistant to external pressure or impact, improving the product's durability and reliability, and helping to provide a better sealing effect. Especially in applications that require prevention of liquid or gas leakage, the seamless connection between the plug 1 and the baffle plate 6 can reduce the risk of leakage, thereby improving the product's sealing performance.

[0022] The expansion mechanism 41 is provided in four sets and is evenly distributed on the surface of the connecting ring 4. Its function is that the four sets of expansion mechanisms 41 are evenly distributed on the connecting ring 4, which can ensure that the contact between the connecting ring and the component to be connected (such as cable, pipe, etc.) is more uniform. This uniform contact not only improves the stability of the connection, but also helps to disperse the stress and pressure during the connection process, and prevents the connection from loosening or being damaged due to excessive local force.

[0023] Working principle: When the operator first holds the expansion mechanism 41 to prevent expansion, and connects the insulating plug to the power interface, once the plug head 1 and connecting ring 4 are inserted into the power interface, the expansion plate 413 will be pressed tightly against the inner wall of the power interface under the action of the compression spring 414, thus fixing the insulating plug. The sensor 101 will monitor the electrical status of the power interface and its surrounding environment in real time, such as voltage and current. Once the sensor 101 detects an abnormal electrical status, such as leakage or short circuit, it will transmit the detected signal to the signal processing circuit 102. The signal processing circuit 102 will amplify and filter the signal transmitted by the sensor 101. The signal is processed and then transmitted to the microprocessor 103. The microprocessor 103 analyzes and judges the signal transmitted by the signal processing circuit 102. If an electrical fault is found, the fault information is sent to the indicator and alarm module 105 through the communication module 104. After receiving the fault information, the indicator and alarm module 105 will issue an audible and visual alarm or other forms of alarm signal to remind the operator to pay attention and take corresponding measures to complete the self-test process. The power supply for the entire discharge detection unit is provided by the power supply module 106, which converts the external power supply into voltage and current suitable for the operation of the discharge detection unit.
