USB Waterproof Connectors Supplier & Manufacturer

Our connector connection types include multi-pin, RJ45, USB, HDMI, fiber optic, Type-C, etc., ensuring stable and reliable signal, data, and power transmission.

Waterproof high-speed connectors are designed to ensure reliable data, signal, and power transmission in harsh outdoor and industrial environments.

What is Waterproof
Cable Gland?

Cable glands are made by combining a central enclosure or body through which cabling can pass with several attachments. These are typically a lock (or check) nut, washers, seal, attachment claw or cone, and a sealing (or compression) nut. Some models also feature two-part enclosures, tags for electrical earthing, PVC shrouding (insulation) or neoprene (rubber) sealing.
Cable glands are connectors used to seal the ends of cables and secure them to plugs, terminals, enclosures or electrical equipment of various kinds. They can protect sensitive electrical wiring from moisture, contamination, corrosion and even flammable gas. Glands are used for cables laid outdoors or in harsh environments, and also for passing cabling through plating or bulkheads. Cable glands are used with all types of power, data, control, instrumentation, automation and telecommunication cable.

Professional Manufacturing Process

How to Manufacture Waterproof Cable Gland?

1

Raw Material Preparation & Injection Molding

High-grade PPO engineering plastic and tinned copper contacts undergo incoming quality inspection. Materials are tested for electrical properties, temperature resistance, and UV stability before entering production.
2

Precision Metal Contact Manufacturing

Automated injection molding machines create connector housings with 0.01mm tolerance precision. Multi-cavity molds ensure consistent dimensions and surface finish across all units.
3

Component Preparation & Integration

Tinned copper contacts are precisely inserted and secured using automated assembly equipment. Crimping force is monitored to ensure optimal electrical connection and pull-out strength.
4

Automated Assembly & Sealing

EPDM rubber gaskets and O-rings are installed using pneumatic presses. Each seal is checked for proper positioning to achieve IP67/IP68 waterproof rating.
5

CCD Visual Inspection & Quality Control

Every connector undergoes electrical testing including contact resistance, insulation resistance, and dielectric strength verification. Mechanical pull tests ensure locking mechanism reliability.
6

Comprehensive Performance Testing

Final inspection checks dimensional accuracy, surface quality, and functionality. Connectors are packaged in anti-static bags with protective caps for safe shipping.

How to install USB Waterproof Connectors

MC4 connectors are integral to the safe and efficient operation of solar panel systems. They facilitate the connection of multiple solar panels, creating strings of panels that are then connected to inverters and other components of the solar power system. The ability to quickly connect and disconnect panels is essential for maintenance and system expansion.
  1. Strip 6-8mm of cable insulation
  2. Insert cable through connector housing
  3. Crimp metal contact onto conductor
  4. Push contact assembly into housing until it clicks
  5. Connect male and female connectors with firm push
  6. Perform pull test to verify secure connection

FAQs

Product & Customization

Q: What is the difference between MC4 and MC3 connectors?

A: MC4 connectors feature an improved locking mechanism, higher current rating (30A vs 20A), and enhanced weather resistance compared to older MC3 connectors. MC4 is the current industry standard.

A: While MC4 connectors have IP67/IP68 ratings for temporary water immersion, they are not designed for permanent underwater use. For marine applications, consider our specialized marine-grade variants.
A: Basic installations require only cable strippers. For professional installations, MC4 crimping tools and spanner wrenches ensure optimal connection quality and easier maintenance.
A: Genuine AGX connectors feature our trademark logo, unique serial numbers, and QR codes for authenticity verification. Always purchase from authorized distributors.
A: AGX MC4 connectors are designed for 25+ year service life under normal outdoor conditions, matching typical solar panel warranties.
A: While the MC4 standard ensures basic compatibility, we recommend using matching connector pairs from the same manufacturer for optimal performance and warranty coverage.
A: Yes, but the system voltage rating is limited by the lowest-rated component. For safety and performance, use consistent voltage ratings throughout the system.
A: Check for proper insertion (audible click), verify polarity, inspect for corrosion or damage, and perform continuity testing. Replace any damaged connectors immediately.
