US Patent 9461403 Robust magnetic connector

Connector inserts and receptacles that are robust, easily manufactured, and provide an improved connector performance. One example may provide a connector receptacle having a power contact located in a ground surface. An insulating layer may be placed between the power contact and the ground surface. The ground surface may be curved or flat, or it may have other shapes. Another example may provide a robust connector insert. This connector insert may include a crimping piece that fits over a cable braiding and is crimped. The crimping piece may then be attached to an attraction plate. A cover or shell may be attached to provide further reinforcement. Another example may provide a connector system having a ground contact and a power contact, where the ground contact is a make-first-break-last contact.
