In the field of industrial connectivity, Amphenol Industrial, as a globally renowned brand, has its products widely used in high-reliability scenarios such as wind power, rail transit, electric vehicles, and industrial automation. With its features of high-temperature resistance, corrosion resistance, large current load, and excellent mechanical strength, it has become the preferred brand for many engineering projects. In recent years, with the continuous improvement of domestic connectors in terms of technology, structural design, and process level, many domestic brands have begun to try to replace some models of Amphenol Industrial. This also prompts us to put higher requirements on the testing capabilities of domestic connectors, thereby driving the systematic investment and management optimization of the company in testing equipment.
The background of investing in domestic connector testing equipmentIn the feasibility analysis of domestic connectors replacing Amphenol Industrial products, we found that, in addition to materials and structure, the professionalism and completeness of the testing process are crucial in ensuring product reliability.
Therefore, starting from 2023, we have successively procured and constructed a full-process testing platform, including the following test modules:
●Insertion and Extraction Force and Durability Test Equipment
●Contact Resistance and Insulation Resistance Tester
● Temperature Rise Test System
Salt Spray Corrosion Test Chamber
● IP grade protection test equipment
High and low temperature cycle test chamber
Share ExperienceIn actual tests, we take the ePower series high-voltage connectors from Amphenol Industrial as a benchmark to carry out systematic verification for domestically produced alternatives in electric vehicle power systems.
The following are several typical experience summaries:
●Insertion and extraction life simulation: We set it to 500 cycles. During the test, the structural strength and spring retention of domestic products are good, and the insertion and extraction variation range is less than 10%, which can meet the requirements of most industrial use cycles.
● Temperature Rise Performance Comparison: Under rated current, the temperature rise of the domestic alternative connector is about 3~5℃ higher than the original Amphenol product, which is still within the acceptable range.
●In the salt spray test: The original Amphenol connector did not show obvious corrosion within 72 hours, while some domestic products showed slight whitening after 48 hours, indicating the need to further optimize the surface coating.
These experiences tell us that while the initial cost of testing equipment is high, it can greatly improve testing efficiency, enhance the verification capability of domestic connectors, and also help customers strengthen their confidence in domestic solutions.
Looking forward to the futureWe believe that with the continuous upgrade of testing capabilities and the continuous accumulation of in-depth analysis, domestic connectors will no longer be just "low-cost substitutes", but will have the performance of "domestic preference" with independent reliability. We will also continue to focus on in-depth research in the connector field and establish a full-chain testing and evaluation system for the new energy and industrial manufacturing markets.
