US Plug Internal Frame Manufacturer – NEMA Plug Inserts

TISDLIP is a professional manufacturer of US plug internal frames and NEMA plug inserts, supplying internal components for American-style power plugs and power cord assemblies. Our products are designed for electrical plug manufacturers, power cord factories, wholesalers and OEM/ODM customers worldwide.

A US plug internal frame, also known as a plug insert or internal support, is an essential component inside an electrical plug. It provides structural support and helps secure the metal pins, electrical contacts and internal wire connections within the plug assembly.

Our product range includes two-pin Type A and three-pin Type B plug internal frames, designed for different NEMA plug configurations, including NEMA 1-15P and NEMA 5-15P applications.

For metal contact components, we offer H59 brass, H62 brass and nickel-plated options, depending on the product design. Pin configurations include seamless hollow pins and solid copper pins to meet different electrical connection and mechanical requirements.

The insulating frame can be manufactured using materials such as PBT and nylon, with heat-resistant and flame-retardant grades available according to the application requirements. These materials provide structural insulation and mechanical support for the internal plug components.

TISDLIP supports customized US plug internal frame manufacturing, including pin structures, metal contact materials, plating finishes, plastic materials and component dimensions. We also support OEM and ODM projects based on customer drawings, samples and technical specifications.

For buyers sourcing NEMA plug inserts, our manufacturing solutions help simplify component procurement for power cords, extension cords, household appliances, electronic equipment and other electrical products.
