Analysis Of The Anti-corrosion Design Features Of Insulation Piercing Connectors!
As a leading brand in the piercing wire connector field, its products have many innovative technologies in anti-corrosion design, which are particularly suitable for long-term stable operation in harsh industrial environments. The following is a detailed explanation of the main features of Xinpengbo Electronics' wire piercing connector anti-corrosion design!
1. Material innovation requirements for industrial connector anti-corrosion design
1. Shell material selection:
PA6 (polycarbonate) engineering plastic is used, which has excellent anti-oxidation and high temperature resistance, and the flame retardant grade reaches UL94 V-0 standard.
Provides metal and plastic dual product lines, the metal shell is made of high-quality alloy material, and the plastic shell uses UV-resistant modified plastic (PBT), specializing in heavy corrosion scenes such as marine equipment.
2. Contact plating technology
The three-layer structure of copper alloy substrate + bottom nickel plating + surface gold plating/palladium alloy effectively inhibits metal diffusion and forms an inert barrier.
A 4μm dense gold plating layer is constructed on the surface of the contact, which significantly reduces the contact resistance (<1mω) and improves the plug-in life (≥500 times).
II. Structural design requirements for anti-corrosion design of industrial connectors
1. Sealing system:
Triple dynamic sealing structure: silicone rubber O-ring + snap-on direct plug lock + patented waterproof structure to achieve IP67 protection level.
The patented direct plug lock design increases the coupling force by 30% compared with the traditional structure, and has stronger anti-loosening performance.
2. Anti-corrosion structure:
Streamlined structure + hollow back top design, taking into account both mechanical strength and corrosion diversion function.
The component matching tolerance is ≤0.05mm, reaching the aviation plug-level accuracy, eliminating local corrosion weak points.
III. Process technology for anti-corrosion design of industrial connectors
1. Precision manufacturing process:
CNC processing and precision injection molding are used to ensure that the flatness of the shell is ≤0.05mm.
High-precision component installation, the contact parts are tightly plugged together to avoid corrosion caused by contact resistance.
Surface treatment technology
The shell has undergone special anti-corrosion treatment, and the salt spray test time is ≥48 hours.
The coating process enables the product's sulfide corrosion tolerance to reach the highest industrial standard.
IV. Environmental adaptability of industrial connector anti-corrosion design
1. Temperature range:
The operating temperature range is -40℃ to 125℃, which can adapt to extreme temperature difference environments.
2. Chemical tolerance:
Excellent acid and alkali resistance, especially suitable for corrosive environments such as electroplating equipment and chemical industry.
Comprehensive dustproof, waterproof and anti-corrosion performance, passed UL, TUV and other international certifications.
V. Application verification of industrial connector anti-corrosion design
1. Actual case performance:
In the high temperature and dusty environment of Nanjing Iron and Steel Plant, the service life of the connector is significantly better than that of conventional products.
Excellent performance in the 72-hour salt spray test, and successful application in the field of marine equipment such as unmanned ships.
2. Test certification:
Strictly tested and certified by UL and TUV authorized laboratories.
Tests such as salt spray corrosion and sulfide corrosion have reached the highest industrial standards.
Industrial connectors provide industrial users with highly reliable connection solutions through anti-corrosion design that integrates material innovation, structural optimization, and precision manufacturing. They are particularly suitable for harsh environment applications such as ports, iron and steel metallurgy, and marine equipment. Its products have formed a complete anti-corrosion technology system, from material selection to structural design to process control, to fully guarantee the long-term stable operation of connectors in corrosive environments.
