Preface
Industrial connectors are used in numerous scenarios, and various environments have a great impact on connectors, such as sulfur dioxide in the atmosphere, sulfides in industrial waste gas, heavy salt in the marine environment, acid and alkali solutions in the workshop, etc. These corrosive substances are important threats to the performance of industrial connectors.
The above corrosion factors can easily damage the connector, especially some connectors that are not designed to meet the standards and have poor quality are more likely to suffer from external corrosion, internal electrochemical corrosion and short circuit, causing the connector to "break down" or even paralyze. Therefore, manufacturers must ensure the anti-corrosion and corrosion resistance of the connector from aspects such as design, material and process.
The connector's anti-corrosion capability is maximized: these points are the key
Industrial-grade connectors usually have very strong anti-corrosion performance, so how is it achieved? The following points are very critical:
1Material selection
Metal material: Use corrosion-resistant alloys (such as stainless steel shell, copper alloy contacts) to prevent corrosion
Plastic material: All-plastic shell connectors can be made of highly corrosion-resistant engineering plastics such as PP, PVC, PBT, etc., especially suitable for harsh environments such as salt spray, acid and alkali
2 Plating process
Electroplating: Gold, silver or palladium alloy is used to form an inert protective layer, inhibit oxidation and sulfurization reactions, and reduce contact resistance
3 Sealing structure
Sealing ring: Made of fluororubber or silicone rubber, it can withstand harsh temperatures and has high elasticity for better fit
4 Precision Technology
Precision processing: precision injection molding, precision compression molding and CNC machine processing, etc., to ensure processing accuracy and quality
Precision assembly: Precision assembly ensures that the housing and internal components fit tightly together, minimizing gaps and preventing corrosion from penetrating
BD series anti-corrosion introduction: Salt spray test time ≥ 72H
1 Salt spray test time ≥ 72H
The BD series industrial waterproof connector is a groundbreaking product that has won the German Red Dot Design Award and the Shenzhen Enterprise Innovation Record Award. It adopts an original design that combines a streamlined body with a hollow arc back top, and has been highly praised by the international mainstream design community. Its anti-corrosion performance is very good. The salt spray test time of the metal model is ≥72H, and the corrosion resistance of the plastic model is better than that of the metal model.
2 How does the BD series connector achieve high corrosion resistance?
01High anti-corrosion material:
①The metal shell is made of high-quality alloy, and the salt spray test time is ≥72 hours;
②The plastic shell is made of SABIC plastic, which is more resistant to salt spray corrosion than the metal one;
③Silicone ring, which also has stronger corrosion resistance
02 Composite plating process:
① Bottom layer: The nickel plating of the contact part is used as the base to inhibit the diffusion of the base metal and improve the adhesion
② Functional layer optimization: The gold plating of the contact part reduces the contact resistance and enhances the anti-oxidation and anti-corrosion performance
03 Reliable connection and sealing:
①Stable snap-on plug-in connection structure and locking structure, more reliable connection
②High-precision molding process ensures that the shell and internal components are more tightly combined, leaving no opportunity for external corrosive substances to penetrate
04 Anti-corrosion performance test:
Relying on UL&TUV authorized laboratories for strict inspection, salt spray test time ≥ 72 hours, meeting standard technical requirements
Application case sharing: unmanned boat
An unmanned boat is an intelligent robot device that uses autonomous navigation or remote control technology to achieve surface operations. It consists of many components, among which the connector is a very critical accessory. Due to the particularity of the use environment, industrial-grade connectors are mostly used.
For unmanned ships, power connectors are needed to provide power input support for the power equipment on board; signal connectors are needed to conduct control signals. Both the power connectors and RJ45 signal connectors of the CNLINKO BD series are used on unmanned ships to achieve the above functions.
The above-mentioned BD series connectors have strong anti-corrosion performance, and the salt spray test time is ≥72H. They can meet the defense and resistance capabilities against various corrosive substances in the environment under the conditions of use of unmanned ships in waters, thereby ensuring the normal operation of the equipment.
In addition, this series of products also has IP68 protection level, high and low temperature resistance, flame retardant, UV resistance and other characteristics, which are adapted to the connector performance requirements of unmanned ships.
At present, this product is also widely used in many fields such as automation equipment, electronic equipment, new energy, electromechanical equipment, mechanical equipment, instrumentation, ships, vehicle-mounted equipment, medical equipment, security, LED display, etc.
