Micro Flat 7-9 Core Watertight Connectors

Product Overview & Series Introduction

The Micro Flat 7-9 Core Watertight Connectors series by HYSF Subsea (Xiamen Chuida Technology Co., Ltd.) represents a specialized, high-performance product line featuring a unique flat profile and low-profile structural design. Engineered specifically for underwater installations with stringent vertical profile constraints, this series provides a highly integrated layout solution that maximizes spatial configuration efficiency while significantly reducing hydrodynamic drag and water flow resistance. Developed through our independent research and development system, this high-density micro flat series breaks the long-standing monopoly of international brands, delivering an elite domestic substitution for core imported subsea components.

Every connector system in this flat series is manufactured using an advanced unibody High-Temperature Vulcanization (HTV) process, integrally molding premium gold-plated copper contacts within a heavy-duty neoprene rubber body to ensure robust mechanical protection and optimal electrical conductivity. To accommodate height-sensitive enclosures, specialized instrument pods, and compact subsea arrays, the series provides complete physical interconnected sets, including:

• Low-Profile Cable Assemblies: Specialized Micro Flat 7-pin and 9-pin Male/Female inline cable assemblies (MCLPIL7M to MCLPIL9F) featuring rugged, highly flexible polyurethane or neoprene rubber outer jackets.
• Compact Bulkhead Receptacles: Precision-machined threaded receptacles (MCLPBH7M to MCLPBH9F) designed with a standard 7/16-20UNF installation thread profile and paired with premium fluororubber O-rings to ensure a tight, leak-proof chassis penetration. The receptacle housing bodies can be customized in elite marine-grade metals including 316L Stainless Steel, Titanium Alloy, or Naval Brass.
• Fitted Protection Components: Durable matching dummy plugs (MCLPDC7M to MCLPDC9F) paired with specialized flat lashing straps (SFLPDLS01) to securely isolate and seal uncoupled channels against moisture ingress and marine biofouling growth.

Key Technical Specifications & Core Features

• High Compatibility & Direct Mating: Precision-engineered to comply directly with international subsea interconnect spacing norms, ensuring full interface interchangeability with global industry brands to drastically lower retrofitting friction and system maintenance costs.
• Wet-Mateable Performance: Adopts precision-toleranced rubber wiping lips that safely isolate electrical paths by displacing moisture during the connection cycle, allowing seamless connecting and disconnecting operations while fully submerged or exposed in volatile splash zones.
• Deep-Sea Hydrostatic Sealing: Rated for operational hydrostatic working pressures up to 60MPa, guaranteeing an absolute zero-leakage security threshold at diving depths reaching 6,000 meters.
• Optimized Electrical Design: Maintains a steady current rating of 5A per pin under a working operational voltage of 550V AC/DC. Backed by an insulation resistance rating of ≥200MΩ @ 1000V DC and an ultra-low contact resistance of <0.01Ω.
• Broad Operating Temperature Envelope: Certified to preserve raw material flexibility, structural latch integrity, and environmental sealing boundaries across extreme temperatures ranging from -60°C up to +80°C.

Industrial Applications & Working Conditions

The Micro Flat 7-9 Core Subsea Rubber Series is uniquely tailored to resolve extreme height limitations and spatial boundaries under high-vibration, deep-water hydrostatic loads, intense salt spray corrosion, and continuous high-load maritime conditions. Critical application deployment sectors include:

1. Height-Constrained Marine Robotic Systems (ROVs & AUVs)

Acts as the primary compact signal breakout interface for low-profile Remotely Operated Vehicles (ROVs) and Autonomous Underwater Vehicles (AUVs). The distinct flat profile allows multi-channel telemetry command loops and localized sensor feeds to be routed closely against flat structural panels, optimizing vehicle aerodynamics, preventing tether entanglement, and maintaining frame buoyancy efficiency.

2. Compact Subsea Sensor Nodes & Monitoring Packages

Extensively deployed to connect partnering environmental monitoring probes, seabed observation networks, hydrophones, and seismic detection packages. The low contact resistance and high pin density (7 to 9 cores) consolidate multiple parallel data signals into a single space-saving hull breakout point with zero signal attenuation.

3. Low-Profile Underwater Network Cameras & Lights

Serves as the mission-critical connection backbone for high-definition underwater cameras, integrated light-and-camera enclosures, and portable diving monitoring boxes. The flat circular contact geometry efficiently routes power inputs alongside high-bandwidth digital command streams through a minimal footprint.

4. Offshore Energy & High-Pressure Sealed Cavity Pods

Utilized across subsea junction boxes, tidal energy platforms, hydraulic power manifolds, and marine defense equipment. The robust neoprene rubber body and unibody vulcanized joints resist biofouling, intense salt spray, and massive mechanical shocks common during heavy-sea deployment and recovery operations.
