Description

The electromagnetic induction socket that induction plug assembly is used

Technical field

The invention belongs to the ferrite technical field that electronic apparatus is used, be specifically related to the electromagnetic induction socket that a kind of induction plug assembly is used.

Background technology

Above mentioned induction plug assembly is a kind ofly without relying on electrically contacting of metallic conductor, connect and be able to electromagnetic coupled mode (or claiming electromagnetic coupled principle) electric energy transmitting and the parts that jointly consist of electromagnetic induction plug and electromagnetic induction socket, this parts have the strong point that fail safe is good, for example, when the light fixture for frequently mobile, not there will be during electric tool and cause electric shock accidents because of electric leakage, frequent mobile light fixture is as followed in industrial and mining enterprises' equipment (as lathe, milling machine, planer, drilling machine and all kinds of Digit Control Machine Tools etc.) illuminating lamp, the projection lamp in photography place, the underwater operation lamp, the underwater luminaire in aquarium (also can claim effect lamp under water), fountain facility lamp, etc..

As aforementioned, the electromagnetic induction plug assembly consists of electromagnetic induction plug and two parts of electromagnetic induction socket, and electromagnetic induction plug (abbreviation plug) coordinates with electromagnetic induction socket (abbreviation 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, winding 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 on the socket magnetic core.

Technical information about induction plug assembly 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 and has considered and be convenient to the winding coil and be the U font by the structural design of socket magnetic core (patent claims the socket iron core), 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, 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.

In view of above-mentioned prior art, be necessary to be improved, the applicant has done useful design for this reason, has finally formed technical scheme described below.

Summary of the invention

Task of the present invention is to provide a kind of and contributes to significantly to simplify core structure, is conducive to easily with the Socket casing reliable fit and have to be convenient to the electromagnetic induction socket that the lead-out wire for coil provides the induction plug assembly of passage to use.

Task of the present invention completes like this, the electromagnetic induction socket that a kind of induction plug assembly is used, comprise a secondary coil magnetic core body, be characterised in that and also include a secondary coil magnetic core body location magnetosheath, described secondary coil magnetic core body is by secondary coil winding core post, secondary coil upper limit magnetic core dish and secondary coil lower limit magnetic core dish form, secondary coil upper limit magnetic core dish directly is formed in an end of secondary coil winding core post, and secondary coil lower limit magnetic core dish directly is formed in the other end of secondary coil winding core post, and form a core post location hole is arranged in the central authorities of the short transverse of secondary coil winding core post, this core post location hole runs through described secondary coil upper limit magnetic core dish and secondary coil lower limit magnetic core dish, the middle position of locating the roof of magnetosheath at described secondary coil magnetic core body offers a magnetic core body location hole of by means of securing member, secondary coil magnetic core body being located for the position corresponding to described core post location hole communicated with the orientation magnetic mantle cavity of secondary coil magnetic core body location magnetosheath, put and also form once level lead-out wires of coil lead-out groove at secondary coil magnetic core body orientation magnetic, this lead-out wires of coil lead-out groove from described magnetic core body location hole, extend to secondary coil magnetic core body location magnetosheath sidewall bottom and be configured to the shape of L font.

In a specific embodiment of the present invention, described secondary coil magnetic core body and secondary coil magnetic core body location magnetosheath are soft magnetic ferrite.

In another specific embodiment of the present invention, the diameter of described secondary coil upper limit magnetic core dish is identical with the diameter of described secondary coil lower limit magnetic core dish.

In another specific embodiment of the present invention, offer one time level winding wire end lead-out groove on described secondary coil upper limit magnetic core dish.

One of technique effect of technical scheme provided by the invention, owing to secondary coil magnetic core body being designed to formed by secondary coil winding core post, secondary coil upper limit magnetic core dish and secondary coil lower limit magnetic core dish, thereby can not only make secondary coil easily winding on secondary coil winding core post, and can be reliably spacing to secondary coil by the upper and lower spacing magnetic core dish of secondary coil, and can save coil rack and significantly simple with respect to the E shape structure in prior art; Two, because secondary coil magnetic core body location magnetosheath both can be to secondary coil magnetic core body location, again can be in use and the Socket casing reliable fit, therefore easy to install; Three, owing at secondary coil magnetic core body orientation magnetic, putting and having offered secondary coil lead-out wire lead-out groove, thereby can make the lead-out wires of coil of secondary coil draw from the orientation magnetic mantle cavity.
