In modern electronic equipment, connectors serve as key components for electrical transmission and signal transmission, and the stability of their performance is directly related to the reliability and safety of the whole machine. The international brand SCHURTER has accumulated profound expertise in products such as power connectors, fuse holders, switches, and EMC filters, especially enjoying a good reputation in the field of high safety grades and international certifications. With the acceleration of the domestic substitution trend, more and more enterprises are beginning to pay attention to the performance of domestic connectors in the testing phase.
One, SCHURTER connector performance benchmarkSCHURTER's connector products cover power input modules, IEC sockets, power outlets with filtering functions, and medical-grade power interfaces, among other features, including:
●In compliance with IEC, UL, CCC and other international certifications, suitable for global markets.
●High reliability materials: flame-retardant shell, environmentally friendly halogen-free plastic, and corrosion-resistant plated metal contacts.
● Widely used in various fields: medical equipment, rail transportation, electric vehicle charging stations, industrial control, data centers, etc.
●The test standards are strict: there are clear specifications for insertion and removal life, insulation resistance, voltage resistance, temperature rise curves, waterproof and dustproof ratings (such as IP67), vibration resistance tests, etc.
These standards and requirements provide an important reference direction for domestic connectors.
Two, performance testing points of domestic connectorsWith the maturity of the industrial chain, domestic connector manufacturers have gradually established a complete performance testing system, mainly including the following test contents:
Mechanical properties
● Insertion and removal life (≥500~5000 times, varies)
Insertion force, extraction force stability
● Contact piece holding force, structural strength test
Electrical performance
Contact resistance and conduction resistance detection
Rated current and voltage bearing capacity
● Voltage and insulation resistance test
Thermal rise test (heat generation under rated load)
Environmental Performance
High and low temperature cycling (-40℃ ~ +125℃)
Salt spray test (to examine corrosion resistance)
●Waterproof and dustproof grade (IP54~IP67)
Vibration and Impact Resistance Test
4. Security and Authentication
●Compliant with RoHS, REACH and other environmental regulations
●Domestic CCC certification, some manufacturers have applied for IEC/UL certification
●Part of the products are subject to special inspections for the medical, power, and rail transit industries
Section 3: Test Results and Gap Analysis●Advantageous links: Domestic connectors have gradually approached or reached international standards in basic mechanical properties (such as insertion and extraction life), conventional electrical properties (rated current, voltage), and general environmental adaptability (dust and moisture resistance).
●Improvement directions: There is still a gap in high-end fields such as medical equipment, electric vehicles, aerospace, etc., in terms of high-temperature aging stability, consistency of special materials, long-life testing (>10,000 cycles of insertion and removal), and electromagnetic interference (EMC) performance.
●Trend: Some domestic manufacturers have benchmarked against international brands, launching power input modules with filtering functions, waterproof and shockproof sockets, and intelligent power interfaces, providing more possibilities for narrowing the gap.
By comparing the performance requirements of SCHURTER with the test performance of domestic connectors, it can be seen that domestic brands can already provide stable and reliable products in the field of conventional applications. In high-end applications, it is still necessary to continuously break through in aspects such as material technology, certification systems, long life, and performance under extreme environments. The substitution of domestic products is not just a choice to reduce costs, but also an important direction for enhancing the security of the domestic supply chain and promoting industrial upgrading.
