Overview

This document provides detailed technical specifications, usage instructions, and product information for RCCN brand strain relief bushings, movable bushings, snap bushings, hole plugs, and related cable protection components. These products are primarily made from UL-certified Nylon 66 or soft PE materials, with fire resistance ratings and designed for protecting electrical wires and cables in various appliances, instruments, and computers.

1. Strain Relief Bushings (SR Series)

Specifications

• Material: UL-certified Nylon 66 (black), flame retardant grade 94V-2, resistant to aging.
• Purpose: Fix and protect power cords to prevent sliding and damage from sharp edges on chassis.
• Usage: Manual assembly using provided sequence diagrams.

Product Variants

Multiple models (e.g., SR-2P-4, SR-3P-4, SR-6N-4) are specified with dimensions (A, B, D, F in mm), mounting hole sizes, wire size compatibility, and applicable chassis thickness. Both flat and round wire types are supported.

Key Parameters

• Wire sizes range from 0.5 mm to 3.5 mm diameter.
• Mounting hole diameters vary from approximately 9.5 mm to 25.5 mm.
• Length and thickness specifications ensure compatibility with different chassis designs.

2. Hole Plugs (HP Series)

• Material: UL Nylon 66, flame retardant 94V-2, oil and corrosion resistant.
• Purpose: Seal unused holes in chassis to maintain aesthetics and prevent ingress.
• Mounting hole sizes range from 9.5x13 mm to 30 mm diameter.
• Designed for chassis thickness up to 3.2 mm.

3. Movable Bushings (KG, KGS, ED Series)

Material and Design

• Soft PE material with various profiles: toothed (KG), sliced (KGS), and U-shaped (ED).
• Flexible and elastic to fit irregular or varying hole sizes.
• Available in transparent and black colors.

Usage

• Cut to required length based on chassis hole size and wrapped around the hole edge.
• Provides strong adhesion, smooth appearance, and protection against wire abrasion.

Dimensions and Packaging

• Slot diameters from 0.7 mm to 8.0 mm.
• Suitable for chassis thicknesses from 0.7 mm up to 8.0 mm.
• Packaged in 10-meter rolls.

Flame Retardant Versions (KGV0, KGSV0, EDV0)

• Similar design and usage as standard versions but with enhanced fire resistance.

4. Snap Bushings (SB Series)

• Material: UL Nylon 66, flame retardant 94V-2.
• Purpose: Convert rough metal holes into smooth cable exit points, protecting cables and insulation.
• Installation: Tool-free, hand-pressed assembly.
• Applicable for metal thickness from 0.8 mm to 3.2 mm.

Dimensions

• Mounting hole diameters from 7.0 mm to 50.1 mm.
• Maximum cable hole sizes and coverage dimensions provided for each model.

5. Grommets (GM/GMC Series)

• Material: Environmentally friendly, aging-resistant soft silicone rubber (standard black, transparent optional).
• Types: Open (GM) and closed (GMC) grommets.
• Used for cable protection in various hole sizes.
• Dimensions range from small (8.5 mm mounting hole) to large (38.1 mm mounting hole).

6. Right Angle and Flexible Strain Relief Bushings

• Material: UL Nylon 66, flame retardant 94V-2.
• Right angle design (SR-F42L) suitable for power cords exiting at chassis bottom.
• Flexible strain relief bushings (SR-F52F, SR-F42LF) provide enhanced protection against wire twisting and damage.
• Dimensions and compatible wire sizes specified.

7. Nylon Movable Bushings (KGN, KGNT, KGNT2 Series)

• Material: UL Nylon 66, flame retardant 94V-2, oil and corrosion resistant.
• Designed for irregular or varying hole sizes with strong elasticity and adhesion.
• KGN is straight type; KGNT and KGNT2 have trapezoidal structures for compatibility.
• Slot diameters range from 0.6 mm to 4.5 mm; suitable for chassis thicknesses from 0.5 mm to 3.2 mm.
• Packaged in 100 pieces, each 25 cm long.

Critical Information and Best Practices

• All products comply with UL standards and have flame retardant ratings (mostly 94V-2).
• Material selection ensures durability, resistance to aging, oil, and corrosion.
• Installation methods vary: some require manual pressing, others wrapping or cutting to length.
• Product selection should consider wire size, chassis hole diameter, and thickness for optimal protection.
• Special models may have minimum order quantities and are not stocked regularly.
