Description
Technical field
The utility model belongs to D.C. contactor technical field, and in particular to a kind of permanent magnetism is contacted with the direct current of electromagnetic combination
Device.
Background technology
D.C. contactor is used in a kind of contactor in DC loop, corresponding with A.C. contactor.Contact system is straight
The key components of contactor are flowed, current-carrying capacity, electric life, the overload capacity of contactor etc. is directly determined by contact system, it
It is control system circuit（Signal）The most direct part of break-make, cavity and the important composition that stud the two parts are contact systems
Part, after being assembled together, flatness and the concentricity in two stud faces can influence the contactor gap of product, and then influence to be out of the line
Journey impacts the performance of product.
At present, popular most of contactor in the market is that the magnetic field for being completely dependent on generating after coil is powered remains up
State, power consumption are very high；Also there is a kind of permanent magnet contactor in the market, the magnetic field that traditional permanent magnet contactor relies on permanent magnet keeps inhaling
Conjunction state, but disjunction main circuit is unable to during decompression, power supply can still keep attracting state after removing, quite dangerous.Therefore,
It is necessary to design a kind of novel energy saving and safe D.C. contactor to solve the above problems.
Invention content
To overcome above-mentioned deficiency of the prior art, the utility model aim is to provide a kind of permanent magnetism and electromagnetic combination
D.C. contactor.
In order to achieve the above objects and other related objects, technical solution provided by the utility model is：A kind of permanent magnetism and electricity
The D.C. contactor that magnetic knot closes including iron cup, is provided with iron plate, is provided with through-hole in the middle part of the iron plate, institute above the iron cup
It states and sleeve is provided in the middle part of iron cup, the diameter of the sleeve is more than the diameter of the through-hole, the sleeve upper end and the iron plate
It connects, the dynamic iron core to pump is provided in the sleeve, the top half of the dynamic iron core includes a connecting rod, institute
Connecting rod is stated through being arranged in a static iron core, the static iron core is coaxially set with the dynamic iron core, the static iron core upper end
The embedded through-hole setting, the connecting rod move up and down setting in the static iron core, and the static iron core is consolidated with the sleeve
It is fixed to set, coil is provided with around the sleeve, permanent magnet is provided with above the coil, the permanent magnet is embedded in the iron
Piece is set.
Preferably technical solution is：The permanent magnet is arranged concentrically for annular and with the through-hole.
Preferably technical solution is：The permanent magnet is coaxially set with the static iron core, dynamic iron core, coil.
Since above-mentioned technical proposal is used, the utility model this have the advantage that compared with prior art：
The utility model is simple in structure, novel in design；Compared to traditional electromagnetic treadle, the utility model is in iron plate
An embedded permanent magnet can play dynamic iron core suction-operated, and therefore, coil only needs the electric current of a very little to generate one
For a faint magnetic field superposition with regard to that can remain up, micro energy lose is energy saving；Permanent magnet is relied on compared to traditional permanent magnetism type contactor to protect
Hold, after decompression can not disjunction, it is quite dangerous, however permanent magnet is not enough to the suction of dynamic iron core in the structure of the utility model
On-state is maintained, it can be with disjunction contactor, securely and reliably during decompression.
