[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] Example 1
[0021] See also Figure 1 - Figure 3 The utility model provides the following technical solutions: a copper-clad aluminum composite bar battery structure connector, including an integrally formed copper-aluminum composite bar 100 composed of a copper cladding 200 and a coated aluminum core 300, and the thickness of the copper-aluminum composite bar 100 is 2mm to 8mm.
[0022] When processing the copper-aluminum composite bar 100, first select a cladding copper tube of suitable size and thickness, then fill the cladding copper tube with aluminum liquid continuously, solidify to form an aluminum core 300, and then place the aluminum billet and the copper billet in a rolling mill, and after multiple rolling, the cladding copper tube is coated on the aluminum surface. The cladding copper tube forms a copper cladding 200, and then the aluminum billet and the copper billet are stretched by a drawing machine to further enhance the bonding force between copper and aluminum. The processing process is convenient and fast, wherein the volume of copper accounts for 25%, and the volume of aluminum accounts for 75%, which effectively reduces the cost of connectors compared to connectors made of pure copper while ensuring conductivity.
[0023] When the copper-aluminum composite bar 100 made of the copper cladding 200 and the aluminum core 300 is used as a battery structure connector, the copper-aluminum composite bar 100 is connected to the battery structure connection surface under high temperature, non-oxidation, and non-pollution conditions to ensure the stability of the connection while ensuring that the connector can be conductive with the battery.
[0024] See also Figure 1 , wherein at least one positioning hole 110 is provided on the surface of both ends of the copper-aluminum composite bar 100, and the positioning hole 110 can be connected to the battery and the conductor conveniently, accurately and quickly. A U-shaped first bending portion 120 is provided at one end of the copper-aluminum composite bar 100, and a flipped second bending portion 130 is provided at the other end of the copper-aluminum composite bar 100. The first bending portion 120 and the second bending portion 130 can enable the connector to connect the battery electrode and the conductor at a suitable angle, and at the same time, the two connectors can maintain a suitable spacing, which can effectively prevent the battery from short-circuiting.
[0025] See also Figure 2-3 In this embodiment, a nickel layer 140 is electroplated on the surface of the copper-aluminum composite bar 100, and the thickness of the nickel layer 140 is 3-6 microns.
[0026] Specifically, the nickel layer 140 can increase the surface hardness of the copper-aluminum composite bar 100, improve its wear resistance and scratch resistance, reduce scratches and damage, prevent damage to the surface of the copper-aluminum composite bar 100 due to oxidation, corrosion or ion erosion, and extend its service life. The nickel layer 140 can make the surface of the copper-aluminum composite bar 100 smooth and uniform, improve the aesthetics, and enhance the market competitiveness of the product. The nickel layer 140 has good electrical conductivity, which can improve the electrical conductivity and connection reliability of the copper-aluminum composite bar 100. At the same time, the nickel layer 140 has good high temperature resistance, which can protect the stability and durability of the copper-aluminum composite bar 100 in a high temperature environment.
[0027] See also Figure 1 In this embodiment, arc-shaped transition portions 150 are provided at the corners of the first bending portion 120 and the second bending portion 130, and the cross-sectional widths of the first bending portion 120 and the second bending portion 130 are equal.
[0028] Specifically, the arc-shaped transition portion 150 can effectively reduce the stress concentration generated at the corner of the copper-aluminum composite bar 100 at the bending portion, which helps to reduce fatigue damage and extend the service life of the copper-aluminum composite bar 100. In addition, the arc-shaped transition portion 150 can make the transition of the bending portion smoother, the appearance more beautiful, and reduce possible mechanical defects and surface defects, while the equal cross-sectional width can ensure that the two bending portions have better consistency when connected, and improve the reliability and stability of the connection.
[0029] See also Figure 1 In this embodiment, the apertures of the plurality of positioning holes 110 are all set to be the same.
[0030] Specifically, by setting the apertures of the positioning holes 110 to be the same, the conductor and the battery can be installed using the same accessories.
[0031] Example 2
[0032] See also Figure 4 The technical feature of this embodiment that distinguishes it from the first embodiment is that positioning grooves 160 are provided on the surfaces of both ends of the copper-aluminum composite bar 100 .
[0033] Specifically, the copper-aluminum composite bar 100 can also be connected to the battery electrode and the conductor through the positioning groove 160 .
