Copper flexible connectors, as key components in power equipment, improper selection may lead to heating, breakage, and even safety accidents.
5 key points to help you choose the most suitable copper flexible connector:
1. Conductivity is the primary consideration.
The conductivity of copper wire flexible connectors directly determines the efficiency of current transmission. It is recommended to choose high-quality copper materials with a copper content of ≥ 99.95%. If used in high-frequency or high current scenarios, special attention should be paid to the matching of cross-sectional area and current carrying capacity.
2. Flexibility and durability.
High quality copper braided wire flexible connectors should have good bending performance and be able to adapt to equipment vibration or displacement. Meanwhile, the uniformity and adhesion of the tin plating layer directly affect its antioxidant capacity. The quality can be preliminarily judged by observing whether the surface is smooth and particle free, and whether there is coating peeling after repeated bending.
3. Environmental adaptability.
In humid, salt spray or high temperature environments, it is necessary to choose products with stronger anti-corrosion performance. For example, in coastal areas, soft connections with tin plating thickness ≥ 0.05mm can be prioritized and ensured to pass salt spray testing (≥ 48 hours). For corrosive environments such as chemical engineering, it is recommended to add additional protective sleeves.
4. The installation method determines the structural form.
Select the appropriate terminal structure (such as bolt holes, crimping terminals, etc.) based on the interface type of the connected device. During installation, attention should be paid to the cleanliness of the contact surface to avoid impurities increasing the contact resistance. At the same time, reserve appropriate length allowance to prevent loose connections due to thermal expansion, contraction, or mechanical stress.
5. Certification and testing reports are quality assurance.
Legitimate manufacturers should provide material testing reports (such as SGS certification) and performance testing data. Before purchasing, it is necessary to verify key parameters such as the product's withstand voltage level and temperature rise test results to ensure compliance with industry standards.
When choosing copper flexible connectors, it is necessary to comprehensively evaluate conductivity, flexibility, environmental adaptability, installation requirements, and certification qualifications. It is recommended to fully communicate the requirements with the supplier based on the actual application scenario, and if necessary, request sample testing. Only products that match the working conditions can ensure long-term stable operation.
