Overview
The double German socket is a standardized electrical outlet widely used in Germany and other European nations. It accommodates two Schuko plugs simultaneously, making it ideal for environments requiring multiple device connections. Designed under the DIN 49440 standard, it ensures compatibility with grounded plugs and incorporates safety features like child-proof shutters. Its robust construction typically uses flame-retardant thermoplastics, ensuring durability and fire resistance.
Structure and Working Principle
This socket comprises two recessed receptacles with spring-loaded contacts to grip plug pins securely. A grounding pin and side clips ensure proper earthing, critical for high-power appliances. The shutters prevent accidental insertion of foreign objects, meeting child safety norms. Internally, copper alloy terminals ensure low resistance and minimal heat generation during operation.
Key Features
Dual receptacles allow simultaneous use of two devices without adapters. The shutters open only when equal pressure is applied to both holes, preventing accidental shocks. Compliance with DIN 49440 guarantees interoperability with Schuko plugs. Some variants include USB ports or surge protection for modern applications.
Application Areas
Commonly installed in homes, offices, and industrial facilities across Germany and EU markets. Ideal for powering appliances like computers, printers, and kitchen equipment. Variants with higher IP ratings (e.g., IP44) are used in bathrooms or outdoor settings where moisture resistance is required.
Maintenance and Precautions
Regularly inspect for loose connections or discoloration, which may indicate overheating. Avoid overloading circuits beyond the rated 16A capacity. Installation should follow local electrical codes, preferably by licensed professionals. For dusty environments, choose models with protective covers.
B2B Procurement Guide
Bulk buyers should prioritize suppliers certified by TÜV or VDE to ensure quality. MOQs typically start at 100 units, with prices decreasing for larger orders. Request samples to test compatibility with existing infrastructure. Lead times vary but average 2–4 weeks for customized orders (e.g., color or branding).
