Description

Technical Field

[0001] This utility model relates to a battery connector, and more particularly to a highly stable oil-immersed battery energy storage connector. Background Technology

[0002] Oil-immersed batteries are a type of battery characterized by immersing battery components (such as the battery plate and electrolyte) in insulating oil to provide superior insulation, heat dissipation, and protection. This method extends battery life and reduces failure rates. Connectors are used as connection points during the charging and discharging of oil-immersed batteries for connecting to electrical equipment or power transmission terminals to facilitate the transfer of electrical energy.

[0003] Currently, in order to facilitate a continuous and stable supply of power from the battery to the electrical equipment, the battery connector and the electrical equipment are often pre-connected. The charging plug on the battery connector is connected to the charging socket on the electrical equipment, so that the power supply to the electrical equipment is achieved by transferring high energy from the battery to low energy from the electrical equipment.

[0004] During prolonged use of oil-immersed batteries, external factors can cause the charging terminals to loosen. This loose connection allows dust to accumulate in the gaps, leading to connection failures and affecting power transmission efficiency. Therefore, it is necessary to design an oil-immersed battery connector that can reliably connect the charging terminals to the device, ensuring efficient power transmission. Utility Model Content

[0005] In view of the above-mentioned problems in the existing technology, the purpose of this utility model is to provide a highly stable oil-immersed battery energy storage connector, which realizes the purpose of the battery connector to connect the charging end to the electrical equipment with high stability and ensure efficient transmission of electrical energy.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A highly stable oil-immersed battery energy storage connector includes a wire body with an input end, a control unit, and an output end connected sequentially on it. Both the input and output ends are equipped with a snap-fit ​​detection unit. Each snap-fit ​​detection unit includes a status light near the control unit, detection components located on the outside of the input and output ends, and a locking seat fixed to the detection components, used for real-time detection of the connection status between the connector and the battery and electrical equipment. The control unit includes an alert component for displaying the power input and output status of the connector.

[0008] Preferably, both sides of the input and output ends are provided with clamping strips, which are made of silicone material and have a concave structure.

[0009] Preferably, the detection component includes a fixing base, a connecting sleeve is provided on the side of the fixing base away from the control unit, and a plurality of detection elements are evenly arranged between the connecting sleeve and the fixing base for detecting the tightness of the connection between the input end and the output end and the battery or electrical equipment.

[0010] Preferably, the detection element includes a pressure sensor, which is externally connected to a pressure bucket. A force-bearing sleeve is provided at the wide end of the pressure bucket, and a spring is provided between the force-bearing sleeve and the pressure bucket. The force-bearing sleeve is in contact with the connecting sleeve.

[0011] Preferably, the pressurizing bucket has a bucket-shaped tubular structure. A limit block is provided on the side of the pressure sensor near the pressurizing bucket, and the pressurizing bucket is connected to the pressure sensor through the limit block.

[0012] Preferably, the clamping seat is provided with an outwardly expanding transition portion, and the clamping seat is provided with chamfered portions on all four sides.

[0013] Preferably, the cable includes an input line and an output line, the reminder component includes an input light and an output light, a circuit protection device and a battery are disposed between the input light and the output light, a reset switch is disposed on one side of the battery, the input line is connected to the input light, the output line is connected to the output light, and the reset switch is connected to both the input light and the output light.

[0014] Compared with existing technologies, the oil-immersed energy storage battery connector provided by this utility model can stably connect the charging end to the electrical device, ensuring efficient power transmission. Specifically, by setting a clamping detection unit and a clamping seat on the input and output ends, the clamping seat can be used to seal the gap between the connector and the battery or electrical device when the connector is connected to the battery or electrical device. This increases the elastic sealing structure at this point, prevents dust from entering, and can also be used for shock absorption, increasing the connection stability between the connector and the battery or electrical device.

[0015] By ensuring the tight fit between the clamping detection unit and the battery or electrical device, the connector installation is completed, and the pressure data between the connector and the battery or electrical device can be monitored. When the detection value changes, the status light will illuminate, indicating a connection abnormality. This allows external personnel to promptly tighten or adjust the connector, ensuring stable use of the connector's charging end and contributing to stable power delivery.

[0016] Furthermore, by using the reminder components, the input and output lights can respectively display the connector's input and output status, the status of the circuit protection components and the battery, facilitating the safe delivery of electrical energy by the control unit. The constantly lit indicator shows the power on / off status of the connector's input or output end, indicating whether the connector's control unit is operating normally, providing favorable conditions for smooth power transmission, facilitating connector maintenance and protection, and providing favorable conditions for the stable use of the connector.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the embodiments of this disclosure will be described in more detail below with reference to the accompanying drawings. Note: The described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0028] As attached Figure 1 To be continued Figure 6 As shown, this utility model provides a highly stable oil-immersed battery energy storage connector, which ensures efficient power transmission by connecting the charging end to the electrical device with high stability. The existing connector includes an input end 11, a control unit 12, and an output end 13 sequentially arranged on the cable. The input end 11 connects to the battery, and the output end 13 connects to the electrical device. By providing a snap-fit ​​detection unit 3 on both the input end 11 and the output end 13, the snap-fit ​​pressure of the connector on the battery and the electrical device can be detected. The snap-fit ​​detection unit 3 includes a status light 31 near the control unit 12, a detection component 32 located on the outside of the input end 11 and the output end 13, and a clamping seat 5 fixedly connected to the detection component 32, used for real-time detection of the connection status between the connector and the battery and the electrical device. When the snap-fit ​​detection unit is in use, the detection component 32 penetrates the battery or the electrical device and is tightly pressed against the surface of the battery or the electrical device. After attaching the connector, the clamping seat 5 is used to seal and tighten the gap between the connector and the battery and electrical equipment, increasing the sealing performance between the connector and the battery and electrical equipment, and preventing dust from affecting the power transmission of the connector. When the squeezing pressure value of the detection component 32 is within the pressure value for stable connection of the connector, the status light 31 can be lit to indicate that the connector end is normally connected. When the squeezing pressure of the detection component 32 is greater than or less than the pressure value for stable connection of the connector, the status light 31 is turned off, indicating that the connection at that end of the connector is loose, which makes it convenient for the staff to tighten or adjust the connector in time, ensuring the stable use of the connector charging end and providing favorable conditions for the stable and continuous power transmission of the connector. Next, a reminder component 4 can be set in the control unit 12 to maintain and detect the working status of the control unit 12, and display the working status of the control unit 12 in a timely manner, realizing the status display of the power input end 11 and output end 13 of the connector.

[0029] To better connect the connector to the battery and electrical equipment, such as Figure 1 and 2As shown, clamping strips 2 can be provided on both sides of the input end 11 and the output end 13. The clamping strips 2 are made of silicone material and have a concave structure with the open end of the concave shape facing outward. This facilitates the use of the clamping strips 2 to increase the sealing structure between the connector and the battery and electrical equipment, increase the connection between the connector and the battery and electrical equipment, increase the friction between the structures, and provide favorable conditions for the stable use of the connector.

[0030] It is worth noting that, for example Figure 1 and 3 As shown, in order to detect the tightness of the connection between the connector and the battery and the electrical device, in some embodiments, the detection component 32 includes a fixing base 321, which is fixed to the input end 11 or the output end 13. Then, a connecting sleeve 322 is provided on the side of the fixing base 321 away from the control unit 12. A plurality of detection elements 33 are evenly arranged between the connecting sleeve 322 and the fixing base 321. When the input end 11 and the output end 13 are installed and used, the detection elements 33 can abut against the battery or the electrical device through the connecting sleeve 322 for detecting the tightness of the connection between the input end 11 and the output end 13 and the battery or the electrical device. In order to better ensure the firm connection between the connector and the battery and the electrical device, the detection elements 33 can be placed in the input end 11 or the output end 13, and a snap-fit ​​pressure detection structure can be added to the inside of the input end 11 and the output end 13.

[0031] like Figure 4 As shown, in some embodiments, the detection element 33 can use an existing sensor detection structure, such as a pressure sensor 331. Then, a pressure chamber 332 is connected to the outside of the pressure sensor 331. The pressure chamber 332 has a bucket-shaped tubular structure, with its narrow end fitting against the pressure sensor 331. A limiting block is provided on the side of the pressure sensor 331 near the pressure chamber 332, and the narrow end of the pressure chamber 332 is connected to the pressure sensor 331 through the limiting block, thus limiting the pressure chamber 332. Next, a force-bearing sleeve 334 is provided at the wide end of the pressure chamber 332. A spring 333 is provided between the force-bearing sleeve 334 and the pressure chamber 332, and the force-bearing sleeve 334 is attached to the connecting sleeve 322. When the input terminal 11 is inserted into the battery and the output terminal 13 is inserted into the electrical device, the force-bearing sleeve 334 will fit against the surface of the battery or electrical device. When the user inserts the connector into the battery or electrical device socket, the spring 333 will deform under force, applying pressure to the pressure sensor 331. When the clamping pressure between the connector and the battery or electrical device reaches the clamping light value of the status light, the insertion can be stopped, completing the stable connection between the connector and the battery or electrical device. Through the real-time detection of the pressure by the pressure sensor 331, the lighting or extinguishing of the status light 31 can indicate whether the charging end of the connector is stably connected, ensuring stable power supply of the connector, reducing energy consumption, and improving the performance of the connector.

[0032] It is worth noting that, for example Figure 3 As shown, in order to ensure a stable connection between the connector and the battery or electrical device, an outwardly expanding transition portion 51 is provided on the clamping seat 5, and the clamping seat is set as a platform-shaped structure to facilitate the through-clamping of the connector with the charging or electrical device socket, thereby increasing the connection firmness. Chamfered portions 52 are provided around the clamping seat 5 to increase the smoothness of the clamping seat 5 and reduce the impact between the input end 11 and the output end 13 and the external structure.

[0033] In some embodiments, to ensure the stable use of the control unit 12, such as Figure 1 and 5 As shown, the reminder component 4 uses input light 41 and output light 42. Utilizing existing connector wiring, the input line from input terminal 11 to control unit 12, and the output line from control unit 12 to output terminal 13, can be connected to input light 41 and output light 42. A circuit protection device 43 and a battery 44 are then placed between input light 41 and output light 42. A reset switch 45 is placed on one side of the battery 44 and connected to input light 41 and output light 42. When control unit 12 is in use, input terminal 11 uses the input line to transmit power to control unit 12. Control unit 12 processes the power using existing power voltage and current regulation technology, and the processed current is transmitted to output terminal 13 via the output line, thus achieving power supply. During the use of the connector, the input light 41 indicates the power-on status of the connector input terminal 11, and the output light 42 indicates the power-on status of the connector output terminal 13. When the control unit 12 malfunctions, the input light 41 or the output light 42 will be turned off. The reminder component 4 uses circuit protection components 43, such as capacitor structures, to protect the structure in the control unit 12. The battery 44 provides power to the normal input light 41 or the output light 42, making it convenient for maintenance personnel to directly grasp the damage during maintenance, increasing the ease of connector maintenance, and ensuring the stable use of the connector. The repaired connector can use the reset switch 45 to turn off the input light 41 or the output light 42 at the same time, providing favorable conditions for the reuse of the connector and the reminder component 4.

[0034] Of course, the above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
