Description
Technical field
The present invention relates to electromagnetic circuit and its relay, more particularly to one kind for direct current monostable, exchange monostable
With bistable electromagnetic circuit system and its electromagnetic relay with the magnetic structure.
Background technology
Relay is the automatic switch element for having isolation features, is widely used in communication, automobile, automatically controls, family expenses
The fields such as electric appliance are one of most important control elements.
Relay is divided into monostable, bistable state, alternating current and direct current, and different application fields is to the relay of difference in functionality
There are different requirements.Bistable relay can meet in the case of not additional power consumption, and relay is made to be maintained at closure or disconnection
State；AC relay can meet the application field requirement of needs alternating current input.It is fast with household, Industry Control etc.
Speed development, relay usage amount is increasing, and cost has become a very important competitiveness；Magnetic circuit system is as relay
Core component, material cost accounting is very big, especially the enameled wire used in magnetic circuit system；If enameled wire dosage compared with
Greatly, while cost is increased, the volume of product can also increased.
The magnetic structure of the prior art, on the one hand, because being limited by product design size, cause magnetic circuit after coil magnetization
Magnetic saturation is easily generated, causes magnetic flux caused by coil that can not be utilized effectively, the magnetic conduction of magnetic circuit is less efficient；The opposing party
The drawbacks of face, the magnetic circuit system generally use iron core of the prior art is mutually fixed with yoke riveting, causes assembly process process poor.
The content of the invention
It is an object of the invention to overcome the deficiency of the prior art, a kind of electromagnetic circuit system and its electromagnetism relay are provided
Device passes through the improvement to yoke structure so that the magnetic circuit system has high magnetic conduction efficiency, can effectively reduce the use of enameled wire
The characteristics of amount and reduction small product size, and have the characteristics that assembly process process is good.
The technical solution adopted by the present invention to solve the technical problems is：A kind of electromagnetic circuit system, including yoke, armature
And coil；The coil is made of bobbin and enameled wire, and the bobbin is equipped with the through hole for being used for being packed into iron core；The yoke
It is made of L-shaped yoke and U-shaped yoke, one side of the L-shaped yoke and a side of U-shaped yoke are respectively by the through hole of bobbin
Both ends to be inserted into mutually recline in the through hole of bobbin and form be packed into bobbin through hole iron core, the U-shaped yoke it is another
The end of side is along as the edge of a knife, to support one end of the armature, the another side of the L-shaped yoke is as pole-face, in coil work
As when be attracted the other end of the armature.
The L-shaped yoke and U-shaped yoke are flat structure.
In one side that one side of the L-shaped yoke mutually reclines with a side of U-shaped yoke as the L-shaped yoke of flat structure
Side and the medial surface of a side of the U-shaped yoke of flat structure mutually recline.
One side of L-shaped yoke and a side of U-shaped yoke are at the both ends of the through hole by bobbin to being inserted into bobbin
After through hole, the end edge on one side of L-shaped yoke is against the medial surface on the base of U-shaped yoke, and the end edge of a side of U-shaped yoke is against
The medial surface of the another side of L-shaped yoke.
The through hole of the bobbin is set to adapt to being inserted in one side of the L-shaped yoke in the through hole of bobbin and U-shaped yoke
A side of iron be affixed after cross-sectional shape hole shape.
One side of described pair of L-shaped yoke being inserted in the through hole of bobbin and a side of U-shaped yoke and bobbin it is logical
Hole is engaged in identical or interference.
The length dimension on one side of the L-shaped yoke is more than the length dimension of the another side of L-shaped yoke.
The width dimensions on one side of the L-shaped yoke are less than the width dimensions of the another side of L-shaped yoke.
A kind of electromagnetic relay, including electromagnetic circuit system described above.
The beneficial effects of the invention are as follows：
1st, as a result of the double yoke structures being inserted into jointly in the through hole of bobbin, and double yokes are by flat structure
L-shaped yoke and flat structure U-shaped yoke composition, one side of L-shaped yoke and a side of U-shaped yoke are respectively by bobbin
The both ends of through hole mutually recline to being inserted into the through hole of bobbin, this double yoke structures, on the one hand, can be effectively increased two yokes
The contact area (plane-plane contact) of iron so as to improve the effective area of magnetic conduction, reduces magnetically saturated probability, ensures coil
Generated magnetic flux all can smoothly flow through magnetic conduction face after excitation, in the magnetic force that pole-shoe face product is larger, in this way, needing phase
In the case of with magnetic force, the dosage of enameled wire can be reduced, so as to reduce enameled wire cost, correspondingly, overall dimensions also just become
It is small；On the other hand, for the medial surface of double yoke structures to inserting, craftsmanship is preferable, assembles accurate positioning.
2nd, flat structure, mould punching good manufacturability are designed to as a result of by L-shaped yoke and U-shaped yoke.
3rd, as a result of L-shaped yoke and U-shaped yoke by bobbin through hole both ends to being inserted into the through hole of bobbin
Middle phase reclines, and medial surface of the end on one side of L-shaped yoke along the base for being against U-shaped yoke, the end edge of a side of U-shaped yoke
The medial surface of the another side of L-shaped yoke is against, assembly process process is good.
4th, a side of one side as a result of L-shaped yoke and U-shaped yoke respectively by bobbin through hole both ends pair
The iron core for mutually reclining and forming in the through hole of bobbin and be packed into bobbin through hole is inserted into, which imitates with high magnetic conduction
Rate, the characteristics of can effectively reducing the dosage of enameled wire and reduce small product size.
