Abstract
The present invention discloses a miniaturized high-speed electromagnet. It includes a locking case shell, an iron core equipped with a stepped hole for mounting cable socket connector and an electromagnetic coil mounted on the pole column of iron core. It is characterized by that the described iron core is an integrated circular ring iron core, in the central position of its ring groove also a central pole column is set and connected together with the iron core, and formed into one body with it, and the described electromagnetic coil is inserted into the between of the described ring groove and central pole column.
Description
Technical field
The present invention relates to a kind of high-speed electro-magnet that is mainly used in the various Electronic Control Ejection System of Diesel Engines.
Technical background
It is in the current electronic controlled diesel ejecting system directly actuated element to be carried out in fuel injection that miniature high-speed sprays electromagnet, also is the crucial power unit of motor conversion, and it is determining the speed of response and the control accuracy of electric-controlling injection system.Chinese patent ZL 2 22523.4 disclosed " driving the high-speed pulse electromagnet by force " patent of invention has solved existing electromagnet and can not satisfy high response speed and big electromagnetic force simultaneously to the directly actuated technical problem of fuel injection processes in diesel oil ECI electronic control injection system.And can be under the situation less than the 20A transient current, the driving force that obtains greater than 300N.But E type silicon steel plate packing iron core and phenolic plastic encapsulation technology that this patent adopts have complex process, encapsulation and the big deficiency of sealing difficulty.Especially the iron core that becomes with E type silicon steel plate packing not only makes the electromagnet volume of its composition bigger, and has occupied electric-controlling injection system installing space greatly, therefore is not suitable for the electric-controlling injection system of small-scale structure.
The objective of the invention is at the deficiencies in the prior art part, provide a kind of simple in structure, can reduce installing space, volume is little, and speed of response is fast, drives powerful miniaturized high-speed electromagnet.
In order to achieve the above object, a kind of miniaturized high-speed electromagnet provided by the invention, comprise that a locking jacket, one are shaped on the iron core that the cable socket step hole is installed and are installed in electromagnetic coil on the iron core pole, it is characterized in that described iron core is a circular iron core of integrated, circular groove middle part at it also is shaped on the center pole that fuses with iron core, described electromagnetic coil is embedded between described circular groove and the center pole, and the lighting outlet of this coil can be drawn from the fairlead of circular groove bottom.
The present invention has following beneficial effect than compared with prior art.
Simple in structure, easy to process.The whole circular iron core that constitutes provides the convenience and the agility of processing for the once-through of machining, for condition has been created in the reduction of large batch of production and processing and assembling cost.
Volume is extra small, and is in light weight, and structure is very compact, and seal form is convenient, solved sealing and the difficult problem of encapsulation.Whole circular core design, coil embeds the center pole, and its volume is reduced at double.Response time is faster, pickup time≤3mS, moment driving force＞250N, drive powerful, responding fast.Has the dual advantageous combination that clapping type closes spiral-type.The high-speed response of diesel oil electric injection system and the problem of miniaturization have been solved.Be suitable for low cost, produce in enormous quantities.

Embodiment
For further specifying preferred embodiment of the present invention, and after conjunction with figs. is specified in, so that be easier to understand for the present invention.But the following stated is only for being used for explaining preferred embodiment of the present invention; be not that attempt is done any pro forma restriction to the present invention according to this; every based on creative spirit of the present invention, any type of modification or the change done all must belong to the category that the invention is intended to protect.
Accompanying drawing has been described a circular iron core 2 that is directly formed by machining integral body, and this iron core can be to be made by electrical pure iron or the whole processing of silicon steel material after-baking.The circular groove middle part of iron core is shaped on the center pole that fuses with iron core, and this center is main work iron core.The rear ends of iron core is shaped on the step hole 4 of the socket that connects actuating cable, and the bottom of circular groove is shaped on fairlead 5.Seal with sealer behind the threading hole threading.Coil 3 is wound on the circular skeleton, and band is inlaid in the coil 3 of skeleton on the center pole in the described iron core circular groove.Behind tap lighting outlet fairlead 5 threading of coil, by the round jacket encapsulation, its space available epoxy solidifies to be filled or seals with sealer, and overcoat is locked on the electromagnetic valve body.The coiling data of coil are determined by dynamic driving force accurate Calculation.
Control by the ECU (Electrical Control Unit) ECU in the Electronic Control Ejection System of Diesel Engines during work.ECU (Electrical Control Unit) ECU sends specific control wave to electromagnet during oil spout, make in the electromagnet coil and to produce the electric current that changes at a high speed and time moment driving force less than 0.3ms, thereby make the spool that links obtain very big acceleration, three spools that connect are closed rapidly, produce inject high pressure.After reaching predetermined emitted dose, electromagnetic force discharges rapidly, and armature this moment high speed opening motor under the valve core spring effect discharges the high pressure fuel road and discharges high pressure fuel, and oil spout stops at once.
