Trailer Handshake Connector (Yellow) – Pneumatic-Electrical Interface for Semi-Trailer Brake Systems

Description

The yellow Trailer Handshake Connector (Part No. 9522010010) is a critical pneumatic-electrical interface between tractors and semi-trailers, integrating a ​7-pin electrical connector and ​pneumatic quick coupler compliant with ISO 7638-1 and SAE J560 standards. Featuring ​UV-resistant nylon 66 housing (UL94 V0 flame-retardant) and ​gold-plated copper alloy contacts (≤5mΩ resistance) with ​EPDM seals (IP69K-rated), it withstands high-pressure washdown, salt spray, and -40℃~125℃ extremes.

Core Functions:

1. ​Dual Transmission: Delivers brake pressure (0.6~1.0MPa) via pneumatic lines and ABS/EBS signals/power (12V/24V DC) via electrical pins.
2. ​Quick Coupling: Self-latching mechanism (≤50N mating force) enables single-person operation.
3. ​Signal Integrity: Shielded channels isolate power (4mm²) from signal lines (1.5mm²) to prevent EMI.

Key Importance:

• ​Safety Critical: Failure may cause brake loss or signal disruption.
• ​Material Impact:
  • ​Contact Plating: ≥0.8μm gold plating ensures low resistance and oxidation resistance.
  • ​Sealing: Dual EPDM seals maintain IP69K after 2000 mating cycles.
  • ​Durability: Housing withstands ≥10J impact (ASTM D256).

Replacement Guidelines:

1. ​Compatibility: Match tractor sockets (e.g., WABCO 7-pin, Euro-7).
2. ​Leak Test: Post-installation pressure drop ≤0.02MPa over 10 minutes.
3. ​Contact Protection: Apply conductive grease (e.g., NO-OX-ID A-Special).
4. ​Wiring Compliance: Follow ISO 11898-2 pinout to avoid ECU damage.
