Description

Technical Field

[0001] This utility model belongs to the field of negative electrode post technology, specifically relating to the circular base plate negative electrode post of power battery structural components. Background Technology

[0002] The circular negative terminal, a key component of a power battery, is typically located at the bottom and connects the internal negative terminal to the external circuitry. Its main body is cylindrical, often made of a highly conductive metal such as copper or nickel-plated steel to ensure efficient energy transfer. The negative terminal's surface is usually designed with threads or snap-fit ​​structures for easy installation of insulating sheets and connectors, while also providing good mechanical strength and corrosion resistance. During battery assembly, the negative terminal must be insulated from the casing to prevent short circuits. Its design also needs to consider vibration and shock resistance to ensure stability and safety under complex operating conditions, making it one of the key components for battery performance and reliability.

[0003] During use, the insulating sheet and connector mounted on the surface of the circular base plate negative terminal on the power battery structural component have some defects:

[0004] First, the insulating sheet is directly fitted onto the negative terminal. This installation method can easily cause the insulating sheet to loosen and shake when the power battery is subjected to vibration or the negative terminal is subjected to mechanical impact, affecting the insulation performance between the negative terminal and the outer shell. Second, the connector is usually fixed to the negative terminal by welding. Welding provides strong connection strength, but it is inconvenient to disassemble and replace the connector when it is deformed by compression. Utility Model Content

[0029] Example

[0030] Reference Figure 1-5 This embodiment of the present invention provides a circular base plate negative terminal post for a power battery structure, comprising:

[0031] The negative terminal 100 includes a terminal 101, an insulating sheet 102 sleeved on the surface of the terminal 101, and a connector 103 snapped onto the end of the terminal 101.

[0032] The reinforcement mechanism 200 includes a fixing component 201 for preventing the insulating sheet 102 from loosening and falling off;

[0033] The replacement mechanism 300 includes a disassembly and assembly component 301 for facilitating the installation and removal of the connector 103, and a contact component 302 for ensuring good contact between the column 101 and the connector 103.

[0034] The insulating sheet 102 is reinforced and installed by the fixing component 201, which solves the problem that the traditional insulating sheet 102 is prone to loosening and shaking when subjected to vibration or mechanical impact, thereby improving the installation stability of the insulating sheet 102 on the column 101 and enhancing the performance of the insulating sheet 102. The disassembly and assembly component 301 facilitates the installation and disassembly of the connector 103, solving the problem of inconvenient disassembly and assembly caused by the traditional connector 103 being connected to the column 101 by welding, and achieving the effect of convenient disassembly and assembly of the connector 103.

[0035] Specifically, the fixing component 201 includes several fixing collars 201a fixedly installed on the surface of the column 101, and several mating grooves 201b formed on the inner surface of the insulating sheet 102 and used in conjunction with the fixing collars 201a to fix the insulating sheet 102.

[0036] The fixed collar 201a has a triangular cross-section and fits into the mating groove 201b. The inclined surface of the triangle facilitates the installation of the insulating sheet 102 on the surface of the column 101.

[0037] Furthermore, the fixing component 201 also includes two mating rings 201c fixedly mounted on the surface of the column 101, and the two mating rings 201c are respectively snapped into the top and bottom of the insulating sheet 102.

[0038] The distance between the two mating rings 201c is the same as the height of the insulating sheet 102. The two mating rings 201c are used to limit the insulating sheet 102 and further enhance the stability of the insulating sheet 102.

[0039] Preferably, the surface of the retaining collar 201a is provided with a plurality of anti-slip strips 201d, which are used to increase the friction between the retaining collar 201a and the mating groove 201b.

[0040] The anti-slip strip 201d is used to increase the friction on the surface of the fixing collar 201a, thereby increasing the friction between the contact surface of the fixing collar 201a and the mating groove 201b, thus preventing the insulating sheet 102 from loosening and shaking on the surface of the column 101 and improving the stability of the insulating sheet 102 in use.

[0041] Furthermore, the disassembly and assembly component 301 includes two locking rods 301a fixedly installed inside the connector 103, a mounting groove 301b opened at the end of the column 101, an annular locking groove 301c opened in the inner cavity of the mounting groove 301b for engaging the locking rods 301a, and two connecting grooves 301d opened in the inner cavity of the mounting groove 301b for disassembling and assembling the locking rods 301a.

[0042] The connector 103 is secured to the end of the column 101 by the cooperation between the locking rod 301a and the annular locking groove 301c, thereby improving the stability of the connector 103. The connecting groove 301d is used to install the locking rod 301a inside the locking rod 301a or to remove it from the locking rod 301a.

[0043] Furthermore, the disassembly and assembly component 301 also includes two slots 301e opened on the column 101, a first spring 301f fixedly installed in the inner cavity of the slot 301e, a ball 301g fixedly installed on the end face of the first spring 301f and used to limit the position of the lever 301a, and a spherical groove 301h opened on the surface of the lever 301a and used in conjunction with the ball 301g.

[0044] Specifically, the first spring 301f compresses the ball 301g, causing the ball 301g to be firmly engaged inside the spherical groove 301h, thereby improving the limiting effect on the lever 301a and ensuring the installation stability of the connector 103.

[0045] It should be noted that the contact component 302 includes several second springs 302a fixedly mounted on the column 101, and a conductive metal ring 302b fixedly mounted on the end of the second springs 302a and used for contacting the connector 103.

[0046] The second spring 302a is used to press the conductive metal ring 302b upward, so that the conductive metal ring 302b and the connector 103 are in full contact, thereby improving the contact performance between the column 101 and the connector 103.

[0047] Specifically, the contact component 302 also includes a mounting groove 302c formed at the end of the column 101, which is used to mount the second spring 302a and the conductive metal ring 302b.

[0048] The mounting groove 302c is used to install the lever 301a and to limit the conductive metal ring 302b.

[0049] In use, due to the elasticity of the insulating sheet 102 itself, the inner ring of the insulating sheet 102 is expanded so that it can be fitted onto the surface of the column 101. The insulating sheet 102 is moved between the two mating rings 201c. When the insulating sheet 102 is released, the insulating sheet 102 will automatically retract between the two mating rings 201c, so that the fixing ring 201a is engaged inside the mating groove 201b, thus completing the installation of the insulating sheet 102.

[0050] When installing connector 103, first place connector 103 on the end of column 101, and insert the locking rod 301a into the connecting groove 301d. When the locking rod 301a is inserted into the annular groove 301c, connector 103 can no longer move down. At this time, connector 103 needs to be rotated 90 degrees so that the locking ball 301g is locked into the spherical groove 301h under the elastic force of the first spring 301f, thus completing the installation of connector 103.

[0051] When connector 103 needs to be disassembled and replaced, rotate connector 103 90 degrees so that the ball 301g is disengaged from the inside of the spherical groove 301h, and rotate the rod 301a to the connecting groove 301d. At this time, the annular groove 301c no longer engages with the end of the rod 301a. Then move connector 103 directly upward to disassemble connector 103.

[0052] In summary, by reinforcing the insulating sheet 102 with the fixing component 201, the problem of the traditional insulating sheet 102 being prone to loosening and shaking when subjected to vibration or mechanical impact is solved, thereby improving the installation stability of the insulating sheet 102 on the column 101 and enhancing the performance of the insulating sheet 102. The disassembly and assembly component 301 facilitates the installation and disassembly of the connector 103, solving the problem of inconvenient disassembly and assembly caused by the traditional connector 103 being connected to the column 101 by welding, and achieving the effect of convenient disassembly and assembly of the connector 103.
