As one of the leading enterprises in the domestic connector field, JONHON (China Avionics Optoelectronics) has been deeply engaged in optical, electrical, and fluid connection technologies for a long time. Its products are widely used in the fields of aerospace, rail transportation, 5G communication, new energy vehicles, and industrial manufacturing.
From official materials:The company owns more than 300 series and over 250,000 varieties of connector products, covering multiple military and civil industries.
Passed the GJB9001C, AS9100D, IATF16949 and other domestic and foreign quality management system certifications, with applicable qualifications in many fields such as aerospace, automotive, and communication.
●In the product performance indicators, some series claim to work stably at extreme temperatures ranging from -65℃ to 150℃, support high-speed transmission, large current power supply, and have IP67 protection level.
In key scenarios such as new energy vehicles, optical communication, and satellite equipment, we can see the presence of China Avic Optoelectronics.
These materials undoubtedly demonstrate that JONHON showcases the strength of a "top domestic brand" on the official level.
Part 1: Differences and Feedback in Actual UseHowever, when engineers actually apply the connector to complex scenarios, they often encounter situations where there is "a slight discrepancy" from the official specifications:
Environmental differences: Laboratory environments are stable, while field environments are subject to complex factors such as high temperature, high humidity, vibration, and salt fog, which lead to a decrease in actual lifespan or contact performance.
Batch consistency: Some customers have feedback that there are slight differences in insertion force, plating process, and other details among connectors of different batches, and a stricter quality sampling inspection is needed.
Failure under extreme conditions: Under high current long-term conduction, strong vibration impact, or corrosive environments, domestically produced connectors may sometimes exhibit issues such as increased contact resistance or reduced reliability.
4. User口碑：Most app feedback indicates stable performance in conventional industrial, new energy, and communication scenarios, but some customers still prefer to retain imported spare parts as a safeguard in extreme fields such as aerospace and marine engineering.
In other words, there is a certain discrepancy between official data and actual usage results, and not all scenarios can "completely replicate the laboratory performance."
Treat the quality of domestic connectors rationallyOverall, is the quality of domestic connectors up to par? The answer is "yes, but it depends on the application scenario."
In most conventional environments and moderate harsh conditions, JONHON's products can meet the requirements, with obvious advantages in cost performance and supply.
In extreme working conditions and projects that heavily rely on stability, domestically produced products still require more verification and redundant design to ensure reliability.
For the procurement party, the reasonable approach is to gradually replace imports according to project requirements, combining the test results of domestic product prototypes, in order to achieve a balance between cost and performance.
Domestic connectors, through more than a decade of technological accumulation, have achieved substitution and breakthrough in multiple industries. JONHON (China Aviation光电) as a representative brand, demonstrates the strength and progress of domestic manufacturers. Although there is still a gap between "official specifications" and "actual feedback," this does not affect the competitiveness of domestic connectors in the vast majority of application scenarios. In the future, with the improvement of material, process, and quality control capabilities, the performance of domestic connectors will be closer to even exceed international standards.
