Description

This IEC 62368 Terminal Probe (1mm diameter, 20mm length) is a precision safety tool tailored for testing audio/video (AV) and information/communication technology (ICT) equipment—specifically targeting tiny terminals, micro-connectors, or ultra-narrow openings. It features an ultra-thin, rigid stainless steel tip (1mm) to access compact spaces without damaging components, paired with a lightweight insulating nylon handle for safe, controlled operation. Designed to mimic accidental contact with small terminals, it verifies that hazardous live parts remain inaccessible, strictly aligning with IEC 62368 standards. Durable and dimensionally stable, it’s essential for manufacturers and labs conducting detailed AV/ICT safety compliance checks.

Standards:

Standards No.	Clause/Figure	Standards Name
IEC 62368-1:2022	Clause 5.3, Figure V.2	Audio/video, information and communication technology equipment – Safety – Part 1: General requirements
UL 62368-1:2023	Clause 5.3 (Aligns with IEC 62368-1 Figure V.2)	Standard for Safety for Audio/Video, Information, and Communication Technology Equipment – Part 1: General Requirements

Specifications:
Probe Type: IEC 62368 Terminal Probe (for micro-terminal/ultra-narrow opening testing)
Probe Material: Stainless steel (ultra-thin, rigid, corrosion-resistant; maintains 1mm diameter accuracy)
Handle Material: Nylon (insulating, non-slip, heat-resistant; ensures secure grip during precise operation)
Key Dimensions:
– Probe Diameter: 1.0 mm ± 0.05 mm
– Effective Probe Length: 20 mm ± 0.2 mm (optimized for micro-terminals)
– Handle Length: 110 mm ± 0.5 mm
– Total Length: 130 mm ± 0.5 mm
Applied Force: No appreciable force (mimics light, accidental contact with small terminals/connectors)
Core Function: Verifies inaccessibility of hazardous live parts in micro-terminals or ultra-narrow openings of AV/ICT equipment per IEC/UL 62368-1

Test Procedures:
1. Inspect the probe for damage (e.g., bent tip, cracked handle) to ensure dimensional accuracy.
2. Power on the AV/ICT equipment and let it reach normal operating mode.
3. Hold the nylon handle and align the 1mm probe tip with the target micro-terminal or narrow opening.
4. Gently insert the probe (up to 20mm effective length) toward potential hazardous live parts.
5. Check if the probe touches any dangerous components (e.g., exposed terminal contacts).
6. Record whether the equipment meets safety requirements (pass/fail).

Applications:
1. Safety testing of wireless earbud charging case terminals (per IEC 62368-1:2022 Figure V.2).
2. Compliance checks for USB-C micro-connectors in smartphones/tablets to block live part access (UL 62368-1:2023).
3. Verification of small AV device terminals (e.g., smartwatch charging pins) for electric shock risks.
4. Quality control for ICT equipment micro-terminals (e.g., IoT sensor connectors) during manufacturing.
5. Post-production audits of portable AV gear (e.g., mini Bluetooth speakers) to meet global IEC/UL standards.
