Description

Technical Field

[0001] The utility model relates to the technical field of copper terminals, in particular to a special copper terminal for argon arc welding. Background Art

[0002] With the rapid development of the manufacturing of lead-acid batteries for electric bicycles, the existing cast welding process has problems such as high energy consumption, high lead fume pollution, poor working environment, and low degree of automation. This project focuses on the process of cast welding six clusters of 12V lead-acid batteries in series through lead bars. The existing cast welding connection process is to dissolve electrolytic lead in a lead pot, and then use a clamp to turn the plate tabs of the six clusters upside down into the 450-500 degree Celsius lead liquid, and then connect the two by hot melt cast welding. This technology uses argon arc welding to laser weld the cluster tabs and lead bars together. Since the argon arc welding process cannot form the end poles, the copper terminals need to be welded together during welding. The existing copper terminals can no longer meet the requirements, and a new terminal needs to be redeveloped.

[0003] Chinese patent CN206349437U discloses a new type of copper terminal for electric vehicle batteries and a battery middle cover containing the terminal, including a copper terminal body, a connecting screw hole is provided in the center of the copper terminal along the longitudinal direction of the copper terminal body, the bottom of the copper terminal is connected to a copper terminal base, the copper terminal base is a cylindrical structure, a new copper terminal base hole is added to the battery middle cover, so that the copper terminal of the new structure can fit well with the battery middle cover, the upper part of the copper terminal base is connected to the copper terminal body at the connection, the terminal connecting piece is provided with a connecting circular hole at the front end of the terminal connecting piece, the depth of the connecting screw hole is 9mm, and the screw hole depth is increased from the original 5mm to 9mm, thereby improving the screw's bite ability and avoiding the copper terminal screw hole slippage phenomenon.

[0004] However, in this technical solution, the copper terminal and the connecting piece are connected separately, and the connection strength is insufficient, which is very prone to shaking, resulting in an unstable overall structure and a short service life. In addition, the separate connection requires additional assembly, which is inconvenient to operate. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of the existing technology and provide a copper terminal specially designed for argon arc welding. By designing the copper column and the connecting piece into an integral shape, it can be used directly without the need for additional assembly, and has better stability, thereby solving the problem of unstable split connection structure in the existing technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A copper terminal for argon arc welding comprises a copper column with a connecting screw hole provided in the middle thereof and a connecting piece provided at one end of the copper column, wherein the connecting piece and the copper column are integrally formed.

[0008] Preferably, the copper column includes: a body and a base arranged at the bottom end of the body, and the connecting piece is arranged on the base.

[0009] Preferably, the body and the base are integrally formed, and the connecting piece and the base are integrally formed.

[0010] Preferably, the outer diameter of the base is smaller than the outer diameter of the body, and a slot is formed between the body and the connecting piece.

[0011] Preferably, the orientation of the connecting piece and the orientation of the copper column are perpendicular to each other.

[0012] Preferably, the width of the connecting piece is equal to the outer diameter of the copper column.

[0013] Preferably, a square hole is provided on the connecting piece.

[0014] Preferably, the size of the square hole ranges from 4.0 mm to 5.0 mm.

[0015] The beneficial effects of the present invention are:

[0016] (1) The utility model improves the overall mechanical strength of the structure by designing the connecting piece and the copper column to be integrally formed, so that they function as a whole without a connection gap. It can also ensure the stability and reliability of the electrical connection and reduce the contact resistance. The integral molding process simplifies the manufacturing process, reduces the assembly steps, and helps to improve production efficiency.

[0017] (2) The present invention ensures the stability and reliability of the electrical connection by providing a slot between the copper column body and the connecting piece. This design can provide additional mechanical support to prevent the connection from being disconnected due to vibration or accidental pulling, thereby ensuring the service life of the copper terminal.

[0018] (3) The utility model sets the connection piece and the copper pillar in a perpendicular direction to each other, which is usually to achieve better space utilization and provide stable mechanical support. It can help save space, make the connection between the copper terminal and the external component more compact, and simplify the assembly process because they can be more easily aligned with the copper pillar, especially in an automated assembly line, thereby improving production efficiency.

[0019] In summary, the utility model has the advantages of good stability, convenient production, long service life, simple operation and easy use. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Example

[0026] like Figure 1 and Figure 2As shown, this embodiment provides a copper terminal dedicated to argon arc welding, including: a copper column 1, a connecting screw hole 11 is provided in the middle of the copper column 1 to connect with external components to provide fixing and supporting functions, and also includes: a connecting piece 2 arranged at one end of the copper column 1, the connecting piece 2 and the copper column 1 are integrally formed, the connecting piece 2 and the copper column 1 are a whole, there is no connection gap, the overall mechanical strength of the structure is improved, and the stability and reliability of the electrical connection can be ensured, the contact resistance is reduced, and the one-piece molding process simplifies the manufacturing process, reduces the assembly steps, and helps to improve production efficiency.

[0027] Among them, the copper column 1 includes: a main body 12 and a base 13 arranged at the bottom end of the main body 12, and the connecting piece 2 is arranged on the base 13. The base 13 can provide additional support for the copper column 1 to ensure the stability and durability of the entire component. It can also be designed into a shape that is easy to install and easy to use.

[0028] At the same time, the main body 12 and the base 13 are integrally formed, and the connecting piece 2 and the base 13 are integrally formed. The shape and size of the copper column 1 and the connecting piece 2 can be flexibly designed as needed to adapt to different application requirements, and the integral forming can reduce errors that may occur during the assembly process, such as alignment problems or unstable connections.

[0029] In this embodiment, the outer diameter of the base 13 is smaller than the outer diameter of the body 12, and a slot 14 is formed between the body 12 and the connecting piece 2, that is, a certain distance is left between the upper end surface of the connecting piece 2 and the bottom surface of the body 12. The slot 14 structure is a common mechanical locking mechanism used to ensure the stability and reliability of the electrical connection. This design can provide additional mechanical support to prevent the connection from being disconnected due to vibration or accidental pulling, thereby ensuring the service life of the copper terminal.

[0030] In this embodiment, the orientation of the connecting piece 2 is perpendicular to the orientation of the copper pillar 1.

[0032] In addition, a square hole 21 is provided on the connecting piece 2, and the size range of the square hole 21 is 4.0mm-5.0mm. The square hole 21 can standardize the connection method, so that the connecting piece 2 can be compatible with a variety of different accessories or equipment, which is convenient for quick connection and replacement. The square hole 21 can provide a larger contact area, which helps to improve the reliability of the electrical connection and reduce the contact resistance.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
