Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electrical connectors, in particular to an electrical connection element. BACKGROUND

[0002] Electrical connection copper bars are widely used in various electrical equipment, such as power systems, automotive electronics, and industrial automation fields. With the rapid development and technological progress of these fields, the performance requirements of electrical connection copper bars are becoming higher and higher. Traditional electrical connection copper bars are usually manufactured by insert injection molding, which can effectively improve production efficiency and reduce costs. However, due to the complex structure of the copper bar and the limitations of injection molding conditions, the wall thickness of the injection layer is uneven, which seriously affects the electrical performance and mechanical strength of the product, thereby reducing the reliability and service life of the product.

[0003] In order to overcome the above problems, the existing technical solutions mainly focus on the following aspects: first, optimizing the design of the injection mold, adjusting the mold temperature, pressure, and injection speed, etc. to improve the injection quality; second, improving the pretreatment process of the copper bar, such as improving the bonding force between the copper bar and the injection material through surface treatment or preheating; third, selecting more suitable injection materials to improve the flowability and filling property of the injection material. Although these methods can alleviate the problem of uneven wall thickness of the injection layer to some extent, it is still difficult to completely eliminate this defect, especially in high-precision and high-performance application scenarios.

[0004] However, these existing solutions still have some shortcomings. First, although optimizing the mold design and injection parameters can partially improve the injection quality, it is still difficult to achieve precise control in the face of complex copper bar structures. Second, the selection of pretreatment processes and materials is also limited by cost and operability, and cannot fully solve the problem. Therefore, how to ensure product quality while reducing defective rates and improving production efficiency has become a technical problem to be solved. CONTENT OF THE INVENTION

By adopting the above technical scheme, the first shell and the second shell can better adapt to the specific shape of the copper bar, ensuring close cooperation between the two and improving the stability and reliability after assembly. At the same time, this design also helps to reduce the stress concentration problem caused by shape mismatch, further improving the mechanical strength and service life of the product.

[0012] In a specific implementable embodiment, the first shell and the second shell are wrapped with an insulating rubber layer.

[0013] By adopting the above technical scheme, the first shell and the second shell are wrapped with an insulating rubber layer, which can effectively prevent the shell from being corroded or damaged by the external environment, improve the service life and reliability of the entire electrical connection copper bar shell element. At the same time, the insulating rubber layer can also enhance the overall strength of the shell, ensuring safety during transportation and use.

[0014] In a specific implementable embodiment, an assembly gap is provided between the first shell and the second shell.

[0015] By adopting the above technical scheme, an assembly gap is provided between the first shell and the second shell, which can effectively avoid deformation or damage of the shell caused by thermal expansion and contraction, improve the stability and reliability of the product. At the same time, the existence of the assembly gap also facilitates the operation during production and assembly, reduces the manufacturing difficulty, and reduces the defective rate.

[0016] In one specific implementation, the two ends of the copper bar are provided with fixing parts, which are arranged outside the shell, and the included angle between the fixing parts and the copper bar is 90 degrees.

[0017] By adopting the above technical scheme, the fixing parts are arranged outside the shell and the included angle between the fixing parts and the copper bar is 90 degrees, which can effectively increase the stability and reliability of the electric connection copper bar during installation, and prevent the problem of poor contact caused by improper installation. At the same time, this design also facilitates connection with other components, improving the assembly efficiency of the entire device.

[0018] In one specific implementation, threaded holes are formed in the fixing parts.

[0019] By adopting the above technical scheme, threaded holes are formed in the fixing parts, which can facilitate fastening connection with other components, improving the installation convenience and stability of the electric connection copper bar shell element. At the same time, the design of the threaded holes makes the fixing parts more secure and reliable during installation, avoiding the problem of poor contact caused by looseness, and ensuring the electrical performance and safety of the product.

[0020] In one specific implementation, the two ends of the copper bar are bent to form two accommodation parts.

[0021] By adopting the above technical scheme, the two ends of the copper bar are bent to form two accommodation parts, which can effectively avoid the interference problem caused by direct contact during installation or use, improving the safety and reliability of the electric connection. At the same time, this design makes the copper bar cooperate more closely with other components, enhancing the stability of the overall structure.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:
