Description

Quiet electromagnet

Technical field

The utility model relates to the electromechanical integration field, refers more particularly to a kind of quiet electromagnet.

Background technology

Electromagnet is a kind of electric energy to be converted into the electric elements of rectilinear motion mechanical energy, and its feature is: add the simple in structure of switching mechanism than motor during rectilinear motion, cost is low, and noise is little, and the life-span is long.Utilize that electromagnetism is ferromagnetic to be had, do not have, can use the switching Current Control; The characteristics that the size of magnetic can be controlled with the number of turn of the power of electric current or coil in fields such as automations, use electromagnet to control in a large number.

Present widely used push electric magnet is made up of housing, quiet iron, moving iron and solenoid, when solenoid is switched on, the quiet iron of solenoid and encirclement solenoid produces magnetic field suction, in the space that moving iron inspiration is surrounded by quiet iron and solenoid, the spring and the push rod of bump electromagnet rear portion actuator, actuator is fulfiled assignment, when solenoid cuts off the power supply, the magnetic field that the quiet iron of solenoid and encirclement solenoid produces disappears, and the spring and the push rod of electromagnet rear portion actuator reset iron.Like this, utilize the switching electricity of solenoid to produce the reciprocating motion that has, do not have the moving iron of control in magnetic field, thereby realize the control of actuator.

At present general electromagnet generally all has an extreme position core magnetic pole, can produce mechanical impact when slide bar moves to the limit, has problems such as very big and life-span of mechanical impact noise is short.

The utility model content

At the weak point that exists in the above-mentioned technology, it is a kind of simple in structure, reasonable in design that the utility model provides, saves energy, noiseless, the quiet electromagnet that suction is big.

For achieving the above object, the utility model provides a kind of quiet electromagnet, it comprises shell, iron core, skeleton, coil groups, slide bar, cover plate, described coil groups is arranged on the described skeleton, described slide bar is arranged in the described skeleton hole, described iron core is arranged at described shell inner bottom part, and described cover plate is fixedlyed connected with described shell.

Described electromagnet also comprises two leads, and described lead is connected with coil on the described skeleton.

Compared with prior art, the utlity model has following advantage:

The quiet electromagnet that the utility model provides, solenoid is wrapped on the skeleton, can obtain high magnetic field intensity, thereby realizes bigger actuating force.Slide bar does not have rigidity during reciprocating motion in the skeleton hole spacing, can not produce mechanical impact sound, can realize noiseless effect.In addition, the utility model is simple in structure, and is reasonable in design, saves energy.

The main element symbol description is as follows:

1, shell 2, skeleton 3, coil groups

Embodiment

In order more clearly to explain the utility model, the utility model will be further described below in conjunction with accompanying drawing.

As shown in Figure 1, the utility model provides a kind of quiet electromagnet, it comprises shell 1, iron core, skeleton 2, coil groups 3, slide bar 5, cover plate 4, coil groups 3 is arranged on the skeleton 2, slide bar 5 is arranged in skeleton 2 holes, and iron core is arranged at the bottom in the shell 1, and cover plate 4 is fixedlyed connected with shell 1, electromagnet also comprises two leads 6, and lead 6 is connected with coil groups 3 on the skeleton 2.

Cover plate is installed on the opening part of shell, and two leads connect respectively on the coil that is wrapped in two skeletons.At the coil middle part one group permanent-magnet is installed, make a permanent-magnetic field, produce a magnetic field during solenoid energising again, will produce relative motion when opposite with permanent-magnetic field, after the position outage that reaches capacity, the movable core of permeability magnetic material remains on extreme position under the effect of permanent-magnetic field; When solenoid obtains a reverse voltage again, can produce a magnetic field opposite again, thereby cause movable core to move once more with present condition, reach the outage of another limit after, under the effect of permanent-magnetic field, keep motionless.Like this, by the energising polarity of conversion solenoid repeatedly, realize the movable core reciprocating motion.

More than disclosed only be several specific embodiment of the present utility model, but the utility model is not limited thereto, any those skilled in the art can think variation all should fall into protection range of the present utility model.
