Description

Technical Field

[0001] This utility model relates to the field of energy storage battery technology, specifically to a terminal block for energy storage batteries. Background Technology

[0002] With the rapid development of new energy technologies, energy storage batteries have been widely used in many fields, such as electric vehicles, energy storage components of renewable energy power generation systems, smart grids, and various portable electronic devices. As a key component connecting the energy storage battery to external circuits, the performance of the terminal block directly affects the reliability, safety, and efficiency of the entire energy storage system.

[0003] To facilitate power supply installation, terminal blocks often adopt a plug-in terminal structure for easier installation. The terminal block relies on a metal head post structure to achieve electrical connection with the outside. The conductive head post and the conductive end block in the end seat are often integrated. As a conductive connection component, it is prone to contact failure due to plugging and unplugging and current erosion. Since the integrated installation structure requires the entire end to be replaced if it is damaged, the operation is difficult and costly. Therefore, a terminal block for energy storage batteries is proposed. Utility Model Content

Figure 4 As shown, the conductive end block 3 is integrally fixed and fitted into the slot in the middle of the end support 2. In order to achieve docking installation with the electrode contact 1, a docking end block 5 is provided at the rear of the conductive end block 3. The docking end block 5 is integrally fixed and installed at the rear of the conductive end block 3. In order to cooperate with the docking end block 5, a docking end sleeve 6 is provided at the front of the electrode contact 1. The docking end sleeve 6 is integrally fixed and installed at the front of the electrode contact 1. The docking end block 5 and the middle sleeve of the docking end sleeve 6 are fitted and inserted. In order to achieve installation limitation, a limiting flap 7 is provided on the upper part of the docking end sleeve 6. The limiting flap 7 is provided on the upper part and rear side of the docking end sleeve 6. A limiting through groove is provided through the middle of the docking end block 5. 8. After pressing, the upper inwardly bent limiting flap 7 is engaged with the limiting through groove 8 for support installation. The rear inwardly bent limiting flap 7 is in contact with the rear of the mating end block 5 for support installation. A flap-type installation limiting structure is adopted. A limiting flap 7 is provided on the edge of the mating end sleeve 6 of the electrode contact 1. After installation, the limiting flap 7 is bent inward by the clamping and pushing of the pressing tool, engaging with the limiting through groove 8 in the middle and in contact with the mating end block 5 at the rear.

Figure 5 As shown, to achieve docking installation, a threaded docking seat 10 is integrally fixed to the rear of the docking terminal 4.

[0031] Working principle or structural principle: During installation, first align and insert the mating end block 5 with the mating end sleeve 6 at the front of the electrode contact piece 1. Then, use a crimping tool to press the mating end sleeve 6 together. During this process, the upper limiting flap 7 of the mating end sleeve 6 bends inward and engages with the limiting through groove 8 in the middle of the mating end block 5 for limiting. Then, the limiting flap 7 at the rear of the mating end sleeve 6 is pressed against it. The inward folding of the limiting flap 7 achieves secondary contact limiting of the installed mating end sleeve 6. After completion, the electrode contact piece 1 is secured with bolts. The plate is connected to the battery electrode. After that, the external shielding sleeve is connected and installed. The end support 2 is locked and limited by bolts. The installation is completed. When the docking terminal 4 is damaged, the circular insertion hole 11 at the front of the threaded docking seat 10 is used as the tool force point. Then, the docking terminal 4 is removed by screwing. Depending on the damage of the docking terminal 4, it is selected to clean and grind for repair or replace it as a whole. Then, the repaired docking terminal 4 is installed into the screw hole at the end of the conductive end block 3 by screwing and tightening. The terminal repair is completed.

[0032] In summary, this terminal block adopts a split-type mating terminal 4, with the mating terminal 4 and conductive end block 3 being set as separate units. A threaded mating seat 10 is provided at the rear of the mating terminal 4. During installation, the threaded mating seat 10 is fastened to the threaded end of the conductive end block 3 to achieve mating installation of the mating terminal 4 and the conductive end block 3. The disassembly and assembly are convenient. During maintenance and repair, the mating terminal 4 can be independently disassembled for cleaning or replacement. This improves the convenience of terminal maintenance and reduces the cost of terminal repair and replacement. A folding-type installation limiting structure is adopted. A limiting folding piece 7 is provided on the edge of the mating end sleeve 6 of the electrode contact piece 1. After installation, the limiting folding piece 7 is bent inward by the clamping and pushing of the pressing tool. It is engaged and supported with the limiting through groove 8 in the middle and abuts and supports the mating end block 5 at the rear. This can effectively improve the installation stability of the mating end sleeve 6 and the mating end block 5, avoid power instability caused by component loosening and displacement, and improve the working stability of the terminal.
