Description
Technical field
The invention belongs to the ferrite technical field that electronic apparatus is used, be specifically related to a kind of magnet structure of electromagnetic induction plugs and sockets.
Background technology
Above mentioned electromagnetic induction plugs and sockets is a kind of without connect the parts that are able to electromagnetic coupled mode (or claiming the electromagnetic coupled principle) electric energy transmitting by electrically contacting of metallic conductor, this parts have the strong point that fail safe is good, for example when the light fixture for frequent mobile, electric tool, not there will be and cause electric shock accidents because of electric leakage, frequent mobile light fixture is as the projection lamp of following illuminating lamp in industrial and mining enterprises' equipment, photography place, subaqual landscape lamp, the fountain establishment landscape lamp in lamp, aquarium for underwater operation, etc.
From known its of the literal paraphrase of above mentioned electromagnetic induction plugs and sockets, by two parts of plug and socket, formed, and plug coordinates with the socket plug, plug by plug casing, be arranged on plug magnetic core in plug casing and plug coil (lead-out wire of plug coil and circuit board electrical connection, and circuit board and the power input line electrical connection) composition of winding on the plug magnetic core; Socket by Socket casing, be arranged on socket magnetic core in Socket casing, be arranged with coil and be arranged on socket coil (lead-out wire of socket coil and straightening and filtering unit electrical connection, and straightening and filtering unit and the power supply output line electrical connection) composition in the socket magnetic core.
Technical information about the electromagnetic induction plugs and sockets can be seen in disclosed Chinese patent literature, " the induction type plug assembly " typically recommended as application for a patent for invention publication number CN102447200A, although this patent application scheme has the 0007th section famous technique effect of specification, but there is the shortcoming of attending to one thing and lose sight of another, this is so-called Gu the structure of having considered socket magnetic core (patent claims the socket iron core) and is convenient to the winding coil and it is designed to the U font, so that the bottom by an input coil winding at the socket magnetic core, and by two output winding windings on the arm of the corresponding both sides of socket magnetic core, and so-called mistake that be plug magnetic core (patent claims the plug iron core) adopted to the stacked formation of silicon steel sheet (patent claims the magnet steel thin slice), be stacked to the plug magnetic core by silicon steel sheet and not only make trouble, and cost is high.Especially, the difficulty of input coil of winding and two output windings on the socket magnetic core be restricted at volume (two output winding UNICOM) each other is large, unavoidably has the situation of mutually interfering in winding process." the induction type plugs and sockets " that and for example utility model patent Granted publication CN2200865Y provides, adopt two magnetic cores, one is the elementary magnetic core of E type for winding E type primary coil, another is the E type secondary magnetic core for winding E type secondary coil, one of shortcoming of this patent scheme, no matter be as the elementary magnetic core of E type of socket magnetic core or as the structure relative complex of the E type secondary magnetic core of plug magnetic core, affect the winding efficiency of coil; Two, often be difficult to location when being installed in housing by the elementary magnetic core of E type and E type secondary magnetic core; Three, generally, coil has a coil rack, be arranged on magnetic core and not only can improve manufacture efficiency together with coil by coil rack, and be conducive to control and the protection to coil, and the E type magnetic core of this patent scheme is difficult to meet this requirement; Four, controls magnetic circuit with whether coordinating of tongue tube and be switched on or switched off because needs rely on permanent magnet, thereby the stability of work is difficult to guarantee, and cause complicated integral structure.
