With the transformation of China's manufacturing industry towards the high-end, the connector industry is also facing the realistic challenge of urgently increasing the localization rate of key components. Especially after international brands represented by Amphenol Sine Systems gradually penetrate the domestic new energy vehicle, intelligent equipment, and engineering machinery markets, the topic of domestic substitution has received more and more attention in the industry.
The product composition characteristics of Amphenol Sine Systems:Amphenol Sine Systems is a sub-brand under the Amphenol Group, focusing on industrial-grade circular connector products. Its main AT, ATP, ATM series connectors have the following characteristics:
●High protection level (IP67 and above): Can meet the needs of use in complex environments.
High terminal precision: high conduction efficiency and low insertion/extraction loss.
● Shell corrosion resistance and impact resistance: mostly using high-performance PA66 and customized rubber sealing rings;
●High compatibility design: Specifically targeted at the Deutsch DT series, supports plug and play.
This structure complexity and performance standard present a great challenge to the supply chain of domestic connector components.
Part Two: The Current Status of Domesticization of Components in Domestic ConnectorsWe started from the perspective of structural decomposition and investigated the key components of domestic substitute manufacturers, the current situation is as follows:
Shell part localization rate: about 90%-95%
Most domestic connector manufacturers have the capability to autonomously inject high-performance engineering plastics (such as PA66+GF) and even possess the ability to independently develop molds, but there is still a gap in material consistency and flame retardant grade control.
Sealed piece domestication rate: about 70%-80%
Seals and gaskets are a shortcoming faced by domestic manufacturers. Some manufacturers still rely on imported silicone rubber or三元乙丙橡胶, and the aging resistance, low-temperature elasticity, and resilience indicators of domestic materials still need to be improved.
Terminal parts domestication rate: about 60%-75%
High precision terminal punch press molds have extremely high requirements for coating consistency. Currently, some manufacturers can produce them stably, but there are still gaps in terms of indicators such as insertion and extraction times and electrical contact impedance compared to original products like Amphenol Sine.
Lock buckle spring and structural components domesticization rate: about 85%-90%
As for mechanical structural components such as shrapnel and latches, the domestic production capacity is already quite high, but precision control and life testing still need to be strengthened.
Key breakthroughs for domesticization enhancementTo fully compete with foreign brands like Amphenol Sine Systems and achieve true "domestic substitution," we believe that efforts should be made in the following aspects:
●Mold design standardization and rapid prototyping capabilities
●Basic material upgrading and配套 modification research and development capability
Structural test platform and multi-station automated detection capability construction
●Joint test and certification cooperation mechanism with vehicle manufacturers and terminal equipment manufacturers
Domestic connectors have already achieved a certain degree of localization on most structural components, but still need to break through in key parts such as seals and terminals. With the advancement of local material processing and mold technology, the complete replacement of foreign products is just a matter of time. Truly powerful domestic brands are continuously approaching and even surpassing international standards.
