Compact 2-Position & 3-Position Terminal Junction Box | Plastic Enclosure for Lighting, Small Appliances & Fan Lights

When designing LED lighting, small home appliances, or fan lights, every millimeter of internal space counts. Balancing wiring safety, assembly efficiency, and compliance with safety standards can feel like a puzzle—especially when working with slim enclosures or compact motor bases. Our TB-01 (2-Position) and TB-02 (3-Position) ultra-small junction boxes solve this challenge. Engineered specifically for tight spaces where standard wiring solutions fall short, these robust plastic enclosures deliver reliable wire protection, easy assembly, and seamless compliance for your mass-production needs.

 

 

For engineers and manufacturers, the pre-production phase often hinges on three critical questions: Where to place the wiring? How to route cables efficiently? Is the setup safe and compliant? Our TB series is built to answer these questions with practical, space-saving design—no compromises on functionality or safety.

 

Our junction boxes are engineered with space efficiency at their core—perfect for products where internal room is limited, eliminating the need to redesign your housing to fit bulky wiring components. With a streamlined design tailored for LED lighting, fan lights, and small appliances, they combine compact size with reliable performance.

• Uniform Slim Profile: Both TB-01 and TB-02 feature a consistent 76mm width and 25mm thickness, allowing them to slide effortlessly into light bodies, fan light motor bases, and small appliance enclosures without disrupting your product’s design or functionality.

This space-saving design is what makes them the top choice for LED Lighting  Wire Connection Boxes and slim-profile appliance wiring. Don’t let bulky wiring solutions limit your product design—our compact junction boxes deliver robust protection without sacrificing space.

 

Perfect for ceiling lights, downlights, and linear lights, these PP Plastic Junction Boxes mount directly inside light bodies. They shield terminal blocks from dust and physical damage while simplifying post-installation maintenance.

 

For fan lights (including ceiling fan lights), the boxes neatly enclose motor wiring.

 

From desk lamps and mosquito killers to electric heaters, these junction boxes organize complex internal wiring. Their robust construction ensures compliance with strict safety regulations.

 

Ultra-thin display cabinets and commercial light boxes demand minimalistic solutions. The TB series’ slim design fits effortlessly into these structures, supporting clean, safe wiring for retail and signage applications.

Core Use Case: Anytime your product requires internal wiring, limited space, safety compliance, and fast assembly—our TB-01 and TB-02 junction boxes deliver.

Durable Materials & User-Centric Design

 

Engineered for industrial durability and ease of use, the TB series prioritizes long-term performance and simplified production workflows.

 

Flame-Retardant Plastic Enclosure

The outer shell is crafted from polypropylene (PP) or polycarbonate (PC), both rated V2 for flame retardancy—critical for meeting global safety standards in electrical appliances. This robust plastic enclosure resists heat, impact, and chemical wear, ensuring longevity in harsh operating conditions.

Secure Wiring Components

• Wire Clamp Screws: φ2.6 × 9.5 mm screws provide a tight, vibration-resistant hold on cables, preventing loose connections that cause safety hazards or malfunctions—essential for fan lights and other electrical products.
• Universal Terminal Fit: Pre-tested with 6 of the most widely used terminal block models (P02, 923, T06, T10, 106, 110), ensuring your existing wiring setup is fully compatible with no modifications needed.

Color Options for Every Application

Choose from four color variants to match your product’s internal design or functional needs:

• White / Black / Apricot: Discreet integration into most product enclosures, blending seamlessly with fan light and appliance interiors.
• Transparent: A game-changer for quality control. These Transparent Wiring Junction Boxesallow assembly teams and inspectors to verify wire placement and terminal crimps without removing the lid—saving time and reducing rework.

The TB-01 and TB-02 are not just junction boxes—they are engineered to streamline your production process, reduce design iterations, and ensure safety compliance. Whether you’re prototyping a new fan light, LED linear light, or scaling production of small home appliances, these ultra-small enclosures pair seamlessly with terminal blocks to deliver clean, secure wiring in the tightest spaces.

Stop compromising on space or safety. Choose the TB series for your next lighting, fan light, or small appliance project—where precision, compatibility, and efficiency meet.
