How to reduce the maintenance cost of medical equipment through magnetic connectors

Case 1-Magnetic Charging Solution for Portable Ultrasonic Diagnostic Instrument

 Problem: The traditional Micro-USB interface causes charging failure due to plug-in loss - an average of 4 repairs per year.

Solution: Use 4pin or 6pin high-current magnetic suction connectors - 5A stable current.

2.2mm precision pitch contacts with gold-plated anti-oxidation layer effectively prevent short circuits and signal attenuation, and the entire body meets ROHS environmental protection standards and halogen-free and lead-free requirements.

Result: The failure rate dropped by 72% within 3 years, and the maintenance cost of a single device dropped from 1,200 to 280.

Technical optimization strategy for magnetic connectors

--Modular design reduces replacement costs

Quick separation of male and female sockets: Magnetic adsorption force (5-8N) enables blind insertion with one hand. When repairing, only the faulty module (such as the monitor battery compartment and endoscope handle) needs to be replaced, without returning the whole machine to the factory.

Standardized interface: Unified 4pin/6pin magnetic protocol, compatible with multiple models of equipment, and 60% reduction in spare parts SKU.

--Improved durability and extended life cycle

Gold-plated contacts + IP68 packaging: Medical-grade 316L stainless steel shell and magnetic contact gold plating process (thickness ≥ 0.5μm), withstanding 10,000 plug-in and unplug and high-temperature and high-pressure disinfection.

Anti-misalignment structure: N/S pole alternating layout ensures precise alignment and avoids contact deformation caused by misalignment.

--Revolutionary breakthrough in maintenance efficiency

Tool-free maintenance: Compared with the time-consuming traditional method, medical staff can complete module replacement on site within 3 minutes.

Remote diagnosis support: Integrated intelligent detection chip, real-time feedback on connection status, and accurate positioning of fault points.
