Description

Technical Field

[0001] This utility model relates to the field of energy storage battery pack technology, specifically to a terminal soldering clamp for energy storage battery packs. Background Technology

[0002] Energy storage battery packs are battery systems used to store electrical energy, typically for balancing power supply and demand, improving energy efficiency, and supporting renewable energy applications. They usually consist of multiple battery cells, such as lithium-ion, lead-acid, and sodium-sulfur batteries. Energy storage battery packs convert electrical energy into chemical energy through electrochemical reactions for storage. When electrical energy is needed, the battery pack releases it by converting the chemical energy back into electrical energy.

[0003] Connection terminals play a crucial role in energy storage battery packs. They are the electrical connection points between individual battery cells within the pack and between the pack and external devices.

[0004] In terms of electrical connections, connection terminals are used to connect multiple battery cells in series or parallel to form a complete battery pack. This connection method allows for adjustment of the battery pack's voltage and capacity as needed. For example, a series connection increases the voltage, while a parallel connection increases the capacity.

[0005] In terms of current transmission, the connection terminals can effectively transmit current, ensuring a stable power supply to the battery pack during charging and discharging. A well-designed connection terminal can reduce resistance, thereby reducing energy loss and improving the overall efficiency of the system.

[0006] In terms of mechanical support, the connection terminals are not only the medium for electrical connection, but also provide mechanical support to ensure that the battery cell remains stable during use and to prevent the connection from becoming loose due to vibration or other external factors.

[0007] In terms of safety, high-quality connection terminal designs can improve the safety of battery packs. They typically take into account overload, short circuit, and other conditions, and can disconnect the circuit in time when abnormalities occur to prevent safety hazards such as fire or explosion.

[0008] In terms of maintenance and replacement, the design of the connection terminals also affects the ease of battery pack maintenance and replacement. Easy-to-access connection terminals make battery cell replacement simpler and reduce downtime.

[0009] Therefore, the reliability of the welding of the connection terminals directly affects the performance and lifespan of the energy storage battery pack. Taking the connection between the BMS acquisition line and the battery pack as an example, there are various structures, including direct soldering, screw fastening, and riveting. Therefore, it is impossible to consider all these factors during procurement, causing significant difficulties in actual production. The main approach is to select the corresponding connection line according to design requirements and then process it according to different product structures, resulting in inconsistencies and reliability issues in the operational process. Utility Model Content

[0010] The purpose of this invention is to provide a terminal soldering clamp for energy storage battery packs, which features good consistency, high reliability and convenient operation.

[0011] This utility model can be achieved through the following technical solutions:

[0012] This utility model discloses a terminal soldering fixture for an energy storage battery pack, including a fixture body. The fixture body is provided with a positioning groove for fixing the connection terminal. The positioning groove includes a central protrusion and an embedded ring groove surrounding the central protrusion. The embedded ring groove forms a wire groove through a side notch. The connection wire is inserted into the wire groove and the connection terminal embedded in the positioning groove is soldered.

[0013] Furthermore, the wire groove is sloped along the positioning groove towards the outer edge of the fixture body, with an inclination angle of 15-45°. By forming a certain inclined surface, it is easier to embed the connection terminal and simplify the operation.

[0014] Furthermore, the number of positioning slots is several, and the diameter of the central protrusion and the corresponding embedded ring groove of the positioning slots are the same or different, so as to meet the soldering requirements between connection terminals of different sizes and connection wires of different thicknesses, and has good versatility.

[0015] Furthermore, the fixture body is made of phenolic resin, ABS engineering plastic, or PP plastic. This facilitates injection molding and, through the insulation properties of the plastic, prevents the solder from firmly bonding to the fixture body, making it easy to remove as a whole.

[0016] Furthermore, the central protrusion is shaped like a frustum, and the contour formed by embedding it into the inner wall of the annular groove is an inverted frustum, which avoids the difficulty of disengagement caused by excessive clamping between the connecting terminal and the positioning groove.

[0017] Furthermore, the conductor can be made of copper, aluminum, iron, or composite materials to meet the soldering requirements of different types and thicknesses of connecting conductors.

[0018] Furthermore, the energy storage battery pack can be a lead-acid battery pack, a lithium-ion battery pack, or a sodium-ion battery pack to meet the usage requirements of different types of battery packs.

[0019] Furthermore, the connecting terminal includes an annular portion and a lead wire rod. The annular portion movably engages with an embedded annular groove, and the lead wire hole movably engages with the lead wire groove. The lead wire hole through which the connecting wire passes is pressed against the underside of the annular portion. This achieves accurate positioning of the solder position of the connecting wire.

[0020] Furthermore, several adjacent wire grooves are separated by square bumps, and the square bumps are of the same height, forming a better visual operating space.

[0021] This utility model discloses a terminal soldering clamp for energy storage battery packs, which has the following beneficial effects:

[0022] First, it has high reliability. By setting up a positioning groove, the shape of the connecting terminal is restricted by the shape of the positioning groove during the soldering process, which effectively ensures that the connecting wire and the connecting terminal are fully soldered and fixed.

[0023] Secondly, it has good consistency. The solder joints of the connecting wires and the connecting terminals are restricted by the shape of the positioning groove, which effectively ensures the consistency of the solder thickness, avoids weak soldering caused by too low solder joint thickness, and also avoids waste of solder caused by too high solder joint thickness.

[0024] Third, it is easy to operate. During operation, the connecting terminal is limited and fixed by the central protrusion, so that the connecting wire is fully embedded and pressed into the bottom of the connecting terminal, avoiding the influence caused by the difference in the wire and reducing the difficulty of operation.
