This product is an innovative, high-protection-grade waterproof junction box with pre-installed terminals. It fundamentally transforms traditional methods like tape wrapping or simple connectors by integrating IP67/IP68-grade sealing protection with modular, quick-connect terminals. It is specifically designed for outdoor, industrial, and infrastructure applications that demand reliable, durable, and standardized electrical connections.
The core value of this junction box lies in providing "ready-to-use," all-weather connection protection. It is no longer just an empty shell but comes with built-in standard terminals. Users simply need to feed in the cables and tighten the waterproof glands to create a fully protected, rainproof, and dustproof connection point. We support providing complete invoices to meet the compliance requirements of project procurement.
The product ensures long-term, stable performance through precision engineering across four key dimensions:
Enclosure Seal: High-Quality Sealing Gasket
A high-quality foam sealing gasket is installed between the cover and the base, forming a tight barrier when compressed.
Combined with the precisely interlocking enclosure structure, it achieves an overall IP67 protection rating for the box, effectively blocking water, moisture, and dust.
Cable Entry: Professional Grade Waterproof Glands
It comes standard with IP68-rated nylon waterproof glands, which are crucial for long-term outdoor use.
A variety of models from M12 to M36 are available to accommodate different cable diameters, ensuring the highest standard of waterproof and dustproof protection at every entry and exit point.
Electrical Connection: Fast & Reliable Terminal Block
The box is equipped with a standard TB series brass busbar terminal block, offering good conductivity and quick wiring (pure copper terminals are available for higher requirements).
The terminal block supports multiple power rating options to match different wire gauges and current needs, enabling tidy, standardized, and safe internal wiring.
Structural Stability: Durable Embedded Brass Inserts
All screw fixation holes feature an embedded brass insert design. Compared to threading directly into plastic, this design effectively prevents stripping and corrosion.
It ensures a tight fit between the cover and base, withstands repeated assembly and disassembly, and significantly enhances product lifespan and maintenance convenience.
Correctly selecting the waterproof gland model is key to ensuring protection. Please match according to your cable's outer diameter (O.D.):
| Waterproof Gland Model | Compatible Cable O.D. Range | Notes & Reference |
|---|---|---|
| M12 | 3 - 6 mm | Suitable for common signal wires, thin control cables. |
| M16 | 4 - 8 mm | Widely applicable for medium diameters. |
| M18 | 5 - 10 mm | |
| M20 | 6 - 12 mm | Common for equipment power cords, main control cables. |
| M22 | 10 - 14 mm | |
| M25 | 13 - 18 mm | |
| M32 | 16 - 20 mm | Suitable for thicker power cables. |
| M36 | 18 - 25 mm | For large-diameter cables or cable bundles. |
Important Notes:
The above compatibility ranges are general guidelines. You must make your selection based on the actual outer diameter of the cable you are using.
For national standard flexible cables, the O.D. may be slightly larger than that of rigid cables with the same cross-section. Please verify before ordering.
For non-standard size or specially structured cables, we recommend sending samples for compatibility testing. Responsibility for waterproof failure due to non-standard cables lies with the buyer.
The product offers two installation schemes to adapt to different on-site mounting needs:
Flange-less Mounting: The back of the box is flat, allowing for fixation via drilling or adhesive, suitable for space-constrained or concealed installations.
Flanged Mounting: The box features mounting lugs on the sides or base, enabling direct screw fixation to walls, poles, or racks for a more secure and convenient installation.
"Stop using electrical tape for connections!"-Traditional tape ages and cracks easily outdoors, leading to risks of leakage, short circuits, or even fire. This product offers a safe, standardized, and lasting alternative.
Enhanced Safety: The fully sealed structure prevents moisture ingress, and insulated terminals avoid exposed wire ends.
Guaranteed Reliability: IP67/IP68 protection ensures connection points remain stable long-term in rain, dust, and corrosive environments.
Easier Maintenance: The modular design facilitates inspection and future circuit modifications, far superior to one-time tape wrapping.
More Professional Appearance: The neat and standardized junction box significantly improves the overall professional image of equipment and projects.
As your professional manufacturing partner, we not only provide this high-performance product but also offer:
Flexible Customization: Support for customizing terminal configuration, gland models, and exterior markings within OEM/ODM frameworks.
