86-Type Safety Socket

Updated: 2026-07-15

Overview

The 86-type safety socket is a standardized electrical outlet named for its 86mm×86mm faceplate dimensions, widely adopted in China and compatible with international wiring systems. It integrates safety features like child-proof shutters and flame-retardant materials, making it a staple in modern construction. Designed for 220V/50Hz power systems, it supports currents up to 16A and is compatible with Type A, C, and I plugs. Its modular design allows easy installation in junction boxes ('底盒'), streamlining electrical fittings in buildings. The 86-type is favored in B2B procurement for its balance of cost, durability, and compliance with GB 2099.3 and IEC 60884 standards.

Structure and Working Principle

The socket comprises a faceplate, contact terminals, and a rear mounting frame. The faceplate, made of PC or ABS plastic, houses brass or phosphor bronze contacts to ensure low resistance and minimal heat generation. Internal springs maintain firm plug contact, while shutters block foreign object insertion unless equal pressure is applied to both live and neutral holes. Behind the faceplate, screw terminals secure wiring (typically 2.5mm² cables), and grounding pins connect to protective earth systems. The rear frame snaps into standardized 86-type junction boxes, anchored by screws. This design ensures quick installation and replacement, critical for large-scale projects.

Key Features

Safety is paramount: flame-retardant materials (UL94 V-0 rated) prevent fire spread, while shutters comply with IP20 ingress protection. High-quality brass contacts resist corrosion and arcing, ensuring longevity under frequent use. Modular frames allow daisy-chaining for multi-gang installations. For B2B buyers, standardization reduces inventory complexity, and color options (white, beige, etc.) cater to aesthetic demands. Some variants include USB ports or smart home compatibility. Load capacity (10A for lighting, 16A for appliances) must align with application needs.

Application Areas

These sockets are ubiquitous in residential apartments, offices, and hotels due to their compact size and safety. In industrial settings, heavy-duty versions with rubber seals (IP44) are used in workshops. Smart buildings integrate them with IoT controllers for energy monitoring. Procurement teams prioritize them for new constructions and retrofits, especially in regions adopting China’s GB standards. Export markets include Southeast Asia and Africa, where 220V systems dominate.

Maintenance and Precautions

Routine checks should verify tight terminal connections to prevent overheating. Avoid using in damp areas unless IP-rated. For high-load devices like air conditioners, dedicate a 16A socket with separate circuit breakers. Installation requires de-energizing circuits and using insulated tools. Miswiring can lead to short circuits or electric shocks. For B2B bulk purchases, request samples to test compatibility with local junction boxes and wiring practices.

B2B Procurement Guide

Bulk buyers should specify certifications (CCC, CE, RoHS) and material grades (e.g., PC for UV resistance). MOQs typically start at 1,000 units, with lead times of 15–30 days. Partner with manufacturers offering custom branding or packaging for projects. Pricing tiers apply: basic models cost ~$1/unit for 10k orders, while smart sockets range up to $10. Verify supplier audits to avoid substandard plastics or thin conductive parts. Shipping terms (FOB, EXW) affect logistics costs.
