Réponse rapide : HYSF underwater connector inserts (male and female pairs) are available for field termination of umbilical cables, ROV tethers, and subsea cable assemblies. Choose from 2-12 pin configurations with stainless steel, titanium, or aluminum housing. Bulk orders (100+ pieces) receive volume discounts with OEM/ODM customization options.
Explication détaillée
Connector inserts (also called contact inserts or modular inserts) are the core components of underwater connector systems. They house the electrical contacts and provide the sealing interface between male and female connector halves. This guide covers everything you need to know about selecting and ordering underwater connector inserts for cable termination applications.
What Are Connector Inserts?
Connector inserts are modular components that contain the electrical contacts (pins and sockets) within a sealed housing. They are designed to be:
- Installed into connector housings: Inserts fit inside the main connector body
- Field-terminable: Can be wired to cables on-site or in your facility
- Interchangeable: Same insert type works across multiple connector series
- Replaceable: Can be replaced if damaged without replacing entire connector
Male vs Female Inserts
| Type | Contact Type | Typical Application | Installation Side |
|---|---|---|---|
| Male Insert | Pins (protruding contacts) | Sensor side, equipment side | Usually installed in bulkhead housing |
| Female Insert | Sockets (recessed contacts) | Cable side, mating side | Usually installed in cable connector housing |
Standard Pin Configurations
HYSF offers connector inserts in standard pin counts suitable for various applications:
| Pin Count | Common Applications | Contact Spacing | Current Rating |
|---|---|---|---|
| 2-Pin | Simple power, single sensor | Standard | Up to 30A |
| 3-Pin | RS232 (TX, RX, GND) | Standard | Up to 10A |
| 4-Pin | RS485, RS232+power, simple sensors | Standard | Up to 10A |
| 6-Pin | Multi-sensor, video+control | Standard | Up to 7A |
| 8-Pin | Multi-channel data, mixed signal/power | Standard | Up to 5A |
| 12-Pin | Complex systems, multiple signals | Compact | Up to 5A |
Insert Series Compatibility
HYSF connector inserts are compatible with multiple connector housing series:
| Insert Series | Compatible Housing | Taille du filet | Pin Count Range |
|---|---|---|---|
| MCBH Inserts | MCBH Series (bulkhead) | 5/8″-18 UNF | 2-12 pins |
| MCIL Inserts | MCIL Series (inline) | 5/8″-18 UNF | 2-12 pins |
| Round Small Inserts | Round Small Series | 3/8″-24 UNF | 2-8 pins |
| Ultra Small Inserts | Série Ultra Small | 5/16″-24 UNF | 2-6 pins |
Field Termination Process
For customers who prefer to terminate cables themselves (like EcoHull and other marine technology companies), HYSF provides connector inserts designed for field termination:
Termination Methods
- Solder Cup: Traditional method, wires are soldered into cups on contact tails
- Crimp Contacts: Faster, more consistent, requires crimping tool
- PCB Mount: For direct circuit board connection (less common for underwater)
Field Termination Steps
- Prepare Cable: Strip outer jacket to expose individual conductors (typically 10-15mm)
- Strip Conductors: Strip each conductor insulation (3-5mm for solder cups)
- Tin Wires: Apply solder to wire ends for easier insertion
- Insert into Contacts: Place tinned wire into solder cup or crimp barrel
- Solder/Crimp: Solder each contact or crimp with proper tool
- Install Insert: Place terminated insert into connector housing
- Secure: Install retaining ring or backshell
- Test: Perform continuity and insulation resistance tests
Required Tools
- Wire Strippers: Precision strippers for small gauge wires
- Soldering Iron: Temperature-controlled, fine tip (for solder cup termination)
- Crimping Tool: Ratcheting crimper for consistent crimps (for crimp contacts)
- Heat Gun: For heat-shrink tubing (optional)
- Multimeter: For continuity testing
- Megohmmeter: For insulation resistance testing (recommended)
Umbilical Cable Applications
Connector inserts are commonly used for umbilical cable termination in various marine applications:
| Application | Typical Pin Count | Cable Type | Insert Recommendation |
|---|---|---|---|
| ROV Tether | 4-12 pins | Multi-conductor umbilical | MCBH or MCIL inserts |
| AUV Charging | 2-6 pins | Power cable | High-current inserts |
| Subsea Sensors | 4-8 pins | Instrument cable | Round Small inserts |
| Underwater Cameras | 6-8 pins | Video+power cable | MCBH inserts |
| Hydrophone Arrays | 8-24 pins | Multi-pair audio cable | Multiple inserts or custom |
Material Selection for Inserts
| Component | Standard Material | Options | Notes |
|---|---|---|---|
| Housing | Engineering plastic (POM) | PEEK, PPS | High strength, excellent insulation |
| Contacts | Brass, gold-plated | Beryllium copper, stainless steel | Gold plating ensures low contact resistance |
| Sealing | Viton O-rings | Silicone, EPDM | Viton for seawater, high temperature |
| Backshell | Acier inoxydable 316L | Titanium, Aluminum | Matches connector housing material |
