In the field of carry capacity, china shr connector is graded 40A at 25 ° C, 433% more than the same size USB-C connector (7.5A max), and contact resistances as low as 0.8mΩ, 62% less than that of the old industrial connector. The test result of a new energy vehicle factory shows that the temperature rise of the SHR connector is not more than 15 ° C under the condition of continuous pulse current 150A, while that of the same German products under the same working state is as high as 28 ° C, and the likelihood of oxidation at the contact surface can be reduced by 74%. TE Connectivity comparison report reports that the SHR connector insulation impedance is maintained at 10GΩ at 85 ° C /85% humidity, 2 orders of magnitude higher than IEC 60512 standard.
Mechanically, SHR connector insertion and withdrawal life is over 15,000 cycles, 500% more than JST XH series’s 2,500 cycles, and insertion and withdrawal force tolerance is kept at ±0.3N, 75% more than Molex Micro-Fit 3.0’s ±1.2N precision. At vibration test, contact displacement is only 2.8μm (frequency 2000Hz/acceleration 30G), 48% tighter than military standard MIL-DTL-38999. Huawei 5G base station project information shows that the SHR connector ensures zero failure under the condition of typhoon-class vibration, and the failure rate of one particular brand equals up to 0.37 times/thousand hours.
In the environmental flexibility, the operational temperature range of the SHR connector is extended to -55 ° C ~+185 ° C, 36% more useful than the same type of Phoenix Contact products (-40 ° C ~+125 ° C). For the salt spray test, the variation of contact resistance of the gold-plated contact (thickness = 0.25μm) after 96 hours’ test is only 3.2%, which is better than the 5% standard required by IEC 60068-2-11 standard. In the high-speed rail project, CRRC Group checked that insulation pressure of SHR connector at 5,000 meters height and 54kPa pressure is also 2500Vrms, or 66% higher than European EN 50155 standard.
According to the cost-benefit analysis, the SHR connector unit price is 0.85−1.2, 42.186 million /MW lower than United States’ Amphenol similar products. According to the production line data of Foxconn, the automatic crimp pass rate of SHR connector was 99.992%, 0.47 percentage points more than that of ordinary connectors, and single wire bundle production cost was $0.23 less.
In high-speed transmission, SHR connector possesses 40GHz high-frequency signal transmission with 0.12dB/mm@10GHz insertion loss, 33% less than Samtec’s HSEC8 series. In 5G millimeter wave testing, its return loss is -42dB at the frequency of 28GHz, and the impedance control accuracy is ±5Ω, 100% higher than the industry standard of ±10Ω. Zte experience shows that bit error rate (BER) of SHR connector on 256QAM modulation is 1×10⁻¹² with 3 times less than the conventional connector, and base station’s throughput is improved by 18%.
In terms of miniaturization innovation, SHR connector has 0.4mm pitch and 3.2mm stack height, 42% less than Hirose FX10 series with the same I/O density. Base station’s throughput is improved by 18%. Its floating structure provides ±0.6mm deviation of alignment, and yield of smartphone motherboard assembly is increased from 98.7% to 99.93%. OPPO folding screen mobile phone projects’ data show that the rate of change of contact resistance of SHR connector after 200,000 bending tests is less than 1.5%, which is 4 times more reliable compared with the mainstream solution in the market, and the annual fault rate is less than 0.03%.
According to China Electronic Components Industry Association 2023, SHR connectors’ domestic industrial market proportion has arrived at 37.6%, while the penetration proportion in new energy vehicles’ three-power system was more than 64%. It is founded on Tesla Shanghai factory supply chain information that the use of SHR connectors has reduced 19% of wiring harness assembly weight, 86% of bicycle expense, and more than 210 million yuan expense per year. On the foreign certification side, SHR connectors gained 143 certificates such as UL1977 and IEC 61984, 29% higher than industry average, and export market share to 42 countries increased 27.3% year by year.
