A magnetic connector has a plug core disposed around a plug contact set and a receptacle core disposed around a receptacle contact set. The plug core defines a generally elongated circular plug core edge. The receptacle core defines a generally elongated concentric-circular receptacle core edge. The receptacle core edge defines an air gap, and the plug core defines an anchor configured to insert into the air gap. A coil is disposed around the receptacle core, and the coil, the plug core and the air gap define a magnetic circuit. The coil is electrically energized so as to form a magnetic field within an air gap, lock the anchor within the air gap and lock the plug contact set to the receptacle contact set accordingly.

Neurostimulation assemblies, systems, and methods make possible the providing of short-term therapy or diagnostic testing by providing electrical connections between muscles and/or nerves inside the body and stimulus generators and/or recording instruments mounted on the surface of the skin or carried outside the body. The assembly affords maximum patient mobility and comfort through differentiated components having minimal profiles and connected by way of detachable and adjustable connections.

A charging structure and an aroma diffuser suitable for a home furnishing small household electrical appliance. The appliance has a chassis and circuit, with a contact thimble arranged on the chassis and penetrating to a lower surface of the chassis. The contact thimble is connected to the circuit. An electrical connection component has a connector and a wire for connecting the connector. The wire is used for accessing a power source. The connector is electrically connected with the thimble when it is abutted with the contact thimble. A magnetic component has a first magnetic member disposed on the chassis and a second magnetic member disposed on the connector. The first magnetic member and second magnetic member are attracted to each other to abut the connector with the contact thimble. A horizontal projection of the chassis covers a horizontal projection of the connector.
