Description
Technical field
The utility model relates to a kind of calutron, and more particularly, it relates to a kind of solenoid.
Background technology
Electromagnet has very many advantages, if the magnetic of electromagnet is with or without using switching Current Control; How many sizes of magnetic can control by the number of turn of the power of electric current or coil; Also magnetic size is controlled by changing resistance control size of current; Its magnetic pole can be controlled etc. by change sense of current, and namely the power of magnetic can change, the presence or absence of magnetic can control, the direction of magnetic pole can change, and magnetic can disappear because of the disappearance of electric current.
At present, be in the patent of CN201420538280.7 in the patent No., disclose a kind of patent of solenoid, comprising: winding and protective circuit; Winding, be made up around backbone winding of the wire being coated with insulating layer coating, be encapsulated in the housing of insulation, the two ends of wire are drawn in housing; Protective circuit; be made up of ready-made circuit board; circuit board is connected with the wire two ends of winding with external power source respectively; power supply is communicated with winding electric; circuit board is also provided with pressure release resistance; pressure release resistance is connected with power supply, at the voltage of power supply higher than the bypass circuit of the conducting formation of pressure release resistance and winding parallel during design load, thus drags down supply voltage.
The prior art can make the voltage fluctuation of external power source can not cause damage to winding; but in this one side of change overcurrent protection critical value; do not improve; if think modified current-carrying value; solenoid is needed to be changed to corresponding model; so not only economical and practical not, and very inconvenient.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of a kind of magnetic variation formula electromagnetic coil assembly that directly can increase critical overload current value.
For achieving the above object, the utility model provides following technical scheme: a kind of magnetic variation formula electromagnetic coil assembly, is arranged on casing for electric appliances, comprises solenoid, iron core and spring, described housing is provided with one with the support of cavity, described solenoid is arranged in support, and the two ends relative to solenoid on described support offer through hole, described iron core is positioned near one end of solenoid, and through described through hole, described iron core has protruding card towards one end of solenoid, described card is positioned at support, and conflict with the sidewall of described support, described card stretches out a gangbar, this gangbar passes from another through hole support through solenoid, described spring housing is located at outside gangbar, and described spring one end and card are conflicted, the other end and housing are conflicted, it is characterized in that: also comprise the magnetic adjustment part for strengthening solenoid magnetic force, described magnetic adjustment part is positioned at the motion path rear of iron core, and this magnetic adjustment part is dismountable is connected on casing for electric appliances.
Further, the outside of described spring is arranged with guide pin bushing, and the two ends of described guide pin bushing are fixedly connected with support.
Further, described guide pin bushing is that insulating material is made.
Further, the material of described guide pin bushing is PA66.
Compared with prior art, the utility model has the advantage of: when needing the electromagnetic coil assembly assembled to be used the device with higher nominal electric current, dismountable mode is utilized to increase magnetic adjustment part at iron core place, magnetic attraction that is contrary and solenoid is produced to iron core, thus the magnetic force added required for iron core adhesive release, thus add the numerical value of overload current, simple, convenient, quick.
