Réponse rapide : HYSF SF (Split Flap) series multi-flap connectors offer 12-24 core underwater connectivity with innovative split-flap design for easy termination. The 3-flap configuration (SF-24-3AW) provides organized wire management (8 conductors per flap), faster installation (40-60% time savings), and superior sealing. Ideal for energy industry, ROV systems, and multi-sensor arrays. Standard delivery is 3-5 days for samples, 10-15 days for bulk orders.
Explication détaillée
Multi-core underwater connectors present unique challenges: managing numerous wires, ensuring reliable sealing, and enabling field serviceability. HYSF’s split-flap design addresses these challenges with an innovative approach that simplifies termination while maintaining superior underwater performance.
What Are Split-Flap Connectors?
Split-flap connectors feature multiple independently opening sections (flaps) that provide organized access to internal contacts:
- Traditional Design: All wires must be threaded through a single opening
- Split-Flap Design: Multiple flaps open independently (2-flap, 3-flap configurations)
- Benefit: Each flap manages a subset of conductors (e.g., 8 wires per flap in 24-core system)
SF Series Product Line
| Model | Total Cores | Flap Count | Cores per Flap | Meilleur pour |
|---|---|---|---|---|
| SF-12-2AW-DC | 12 cores | 2 flaps | 6 cores/flap | Medium-density connections |
| SF-16-3AW-DC | 16 cores | 3 flaps | 5-6 cores/flap | Multi-sensor arrays |
| SF-24-3AW-DC | 24 cores | 3 flaps | 8 cores/flap | High-density power/data (most popular) |
| SF-36-4AW-DC | 36 cores | 4 flaps | 9 cores/flap | Very high-density systems |
Key Advantages of Split-Flap Design
1. Organized Wire Management
With 24 conductors to terminate, organization is critical:
- Grouped Conductors: 8 wires per flap (for SF-24-3AW)
- Color Coding: Easy to label and identify by flap
- Reduced Tangling: Work on one section at a time
- Clear Access: Each flap provides unobstructed access to its contacts
2. Faster Termination
Time savings compared to traditional multi-core connectors:
- Traditional: Thread all 24 wires through single opening (time-consuming)
- Split-Flap: Open flap, terminate 8 wires, close flap (repeat 3x)
- Time Savings: 40-60% reduction in termination time
- Error Reduction: Less chance of wiring mistakes
3. Superior Sealing
Multiple sealing points provide enhanced protection:
- Flap Seals: Individual O-ring seal on each flap
- Body Seal: Main connector body seal
- Cable Entry Seals: Individual cable gland seals
- Redundancy: Multiple barriers against water ingress
4. Field Serviceability
Easy maintenance and repair in the field:
- Individual Flap Access: Open only the flap needing service
- Partial Re-termination: Replace damaged wires without full rework
- Inspection: Visual inspection of contacts without full disassembly
- Testing: Test individual flaps independently

Installation Best Practices
Pre-Installation Checklist
- ✓ Verify connector model matches requirements
- ✓ Check all flaps open and close smoothly
- ✓ Inspect O-rings for damage or debris
- ✓ Review pin assignment diagram
- ✓ Prepare proper tools (strippers, soldering iron/crimper, multimeter)
- ✓ Label wires according to flap assignment
Step-by-Step Termination
- Plan Wire Assignment: Assign wires to flaps (e.g., 1-8 to Flap 1, 9-16 to Flap 2, 17-24 to Flap 3)
- Open Flap 1: Release latch, open first flap fully
- Prepare Wires 1-8: Strip insulation (3-5mm for solder, 6-8mm for crimp)
- Terminate Wires 1-8: Solder or crimp to contacts (follow pinout diagram)
- Inspect Flap 1: Verify all connections, check for cold solder joints or poor crimps
- Close Flap 1: Secure latch, verify O-ring is seated properly
- Repeat for Flap 2: Follow same process for wires 9-16
- Repeat for Flap 3: Follow same process for wires 17-24
- Final Testing: Continuity test all 24 conductors, insulation resistance test
- Documentation: Record test results, label connector with date and technician ID
Common Mistakes to Avoid
- ❌ Crossing Wires Between Flaps: Keep wire assignment organized
- ❌ Damaging O-Rings: Handle flaps carefully, inspect seals before closing
- ❌ Overtightening Latches: Secure but don’t force (can damage seals)
- ❌ Skipping Testing: Always test before deployment
- ❌ Poor Wire Preparation: Proper stripping length is critical
