[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.
[0024] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a DB26 energy storage signal lead-out cable design, including a cable body 1, a one-piece molded black plastic shell 2 on the left side of the cable body 1, a male connector 21 on the left side of the one-piece molded black plastic shell 2, a terminal body 3 on the right side of the cable body 1, a terminal plug 4 on the right side of the terminal body 3, a protective cover 5 on the left side of the male connector 21, and a terminal pin seat 6 on the right side of the terminal plug 4.
[0025] The male connector 21 and the one-piece molded black plastic shell 2 are integrally molded structures. The male connector 21 is a DB26-3 row 26 pin structure. The terminal body 3 has 26 tubular plug terminals for signal connection and transmission. The terminal plug 4 and terminal pin socket 6 are 15EDGKM-3.81MM-13Pin Phoenix terminal structures. The two work together to realize signal conversion.
[0026] The protective cover 5 is a DB26 dust cover that fits tightly onto the male connector 21 to prevent dust and foreign objects from entering. The cable body 1 is a standard 1.5-meter UL2464-26AWG*26C-300V-80℃ cable with a shielding layer, used to ensure the stability and anti-interference of signal transmission. The factory QR code on the cable body 1 contains part number information, manufacturing time information, and serial number information, which facilitates product tracking and management. When this energy storage DB26 signal lead cable is used in an energy storage system, the signal is transmitted from the cable body 1 through the terminal body 3 composed of tubular connectors to the terminal plug 4, and then through the terminal pin socket 6 to other modules. The male connector 21 is used to interface with external devices to realize signal input and output. The shielded cable body 1 effectively resists external electromagnetic interference and ensures stable signal transmission. When maintenance is required, the fault point can be quickly located through the pin definitions, wiring labels, and QR code information on the cable, and corresponding repairs or component replacements can be performed.
[0027] Working Principle: When this DB26 signal lead cable is used in an energy storage system, its operation encompasses multiple key stages, including signal input, transmission, conversion, and output. All components work together to ensure stable and accurate signal transmission. During the signal input stage, signals from various sensors, controllers, or other devices in the energy storage system are connected to the cable via the male connector 21. The male connector 21, as the signal entry point, utilizes its standardized DB26-3 row 26-pin structure to achieve quick and reliable connection with external devices. Its easy plugging and unplugging not only facilitates equipment installation and debugging but also reduces the risk of signal transmission failures due to improper connections. Simultaneously, the male connector 21 is tightly integrated with the one-piece molded black plastic shell 2. The black shell 2 not only provides physical protection for the male connector 21 but also acts as electromagnetic shielding to a certain extent, reducing the impact of external electromagnetic interference on signal input. After the signal enters the cable body 1, it begins internal transmission. The cable body 1 uses a standard 1.5-meter UL2464-26 connector. The AWG*26C-300V-80℃ shielded cable features a special design that gives it excellent anti-interference capabilities. The shielding layer effectively blocks external electromagnetic fields from interfering with the internal signal transmission of the cable, ensuring stable and accurate signal transmission. Whether in complex electromagnetic environments or during long-distance signal transmission, the shielded cable body 1 guarantees signal integrity, preventing signal distortion and attenuation, thus laying a solid foundation for reliable communication between modules of the energy storage system. As the signal is transmitted in the cable body 1 to the right, it reaches the terminal body 3, which consists of 26 tubular connectors. As a key node for signal transmission, the tubular connectors, through good electrical connection, stably transmit the signal from the cable body 1 to subsequent components. Its special structural design and material selection ensure reliable conductivity and mechanical stability during long-term use, effectively avoiding signal transmission interruptions caused by poor contact or loose terminals. The signal is then transmitted from the terminal body 3 to 15EDGKM-3.The 81mm-13pin terminal plug 4, via terminal pin socket 6, is used to connect to other modules for signal output and distribution. Terminal plug 4 and terminal pin socket 6 work together, and thanks to their clearly marked hole positions, signals can be flexibly defined and ordered according to actual needs. During signal transfer, their internal conductive structures are in close contact, ensuring smooth signal transmission. Furthermore, their rational structural design and manufacturing process guarantee high efficiency and stability in signal transfer. Whether under normal operating conditions of the energy storage system or facing various complex operating conditions and signal changes, terminal plug 4 and terminal pin socket 6 can accurately complete the signal transfer task, providing reliable signal support for the collaborative work between modules of the energy storage system. When the energy storage system requires maintenance, the design advantages of this signal lead cable are fully demonstrated. The clearly marked wiring labels on the cable body 1... Maintenance personnel are provided with intuitive information on line functions and connections, enabling them to quickly understand the purpose and routing of each line. Additionally, factory QR codes containing part number, manufacturing date, and serial number information allow personnel to quickly obtain detailed product information, including production batch, production date, and technical parameters, using a scanning device. This information is crucial for fault diagnosis and component replacement, helping maintenance personnel quickly locate the fault and select appropriate replacement parts, significantly improving the efficiency and accuracy of maintenance work. For example, when an abnormal signal transmission is detected, maintenance personnel can scan the QR code to query relevant information about the cable, and combined with wiring labels and pin definitions, quickly determine the possible location of the fault, such as whether the cable is damaged or the terminals are loose, thus taking targeted repair measures to promptly restore signal transmission and ensure the normal operation of the energy storage system.
