Abstract
An electromagnetic direct-drive contactor is provided. Electromagnets, a static contact, a push rod and a spring are arranged inside a shell; the upper end of the push rod is fixed with a moving contact, and the lower end of the push rod is provided with magnets. When the electromagnets are energized, a magnetic force is utilized to drive the push rod, such that the moving contact and the static contact can be closed. By means of the above manner, the contactor does not require holding current, and therefore, the load of a coil can be decreased, and the coil will not emit heat or only emit a little heat, and a moving iron core is omitted, and as a result, a greater energy-saving property can be realized, and thus, the safety performance and the sensitivity of the contactor can be improved.
Description
Technical field
The present invention relates to a kind of electric elements, specifically cut off or connect the device of power supply in a kind of circuit.
Background technology,
Common contactor, mostly be used as drive coil for single coil, and driving mechanism structure complexity, the tension force that the time need overcome back-moving spring in work promotes moving iron core action, therefore the power of coil wants big, it is big that power increases not only power consumption, and easily heating, especially contactor under the power condition of working frequently, the easier heating of coil, for a long time the accumulation of heating and heat can cause coil to catch fire, though people have done many improvement, keeps away also that unavoidably having generates heat and catch fire the generation of phenomenon, this not only directly influences the useful life of contactor, but also can cause the malfunction of contactor, if contactor can not in time open and close at work, cut off and connect power supply, will breed disaster so, the electric automobile spontaneous combustion of hearing of is often arranged, and mostly is the contactor heating, causes whole element afunction to cause.
Summary of the invention
In order to remedy the above-mentioned deficiency of contactor, the invention provides a kind of electromagnetic direct-drive contactor, this contactor adopts the form of twin coil bi-directional drive, directly drives the push rod of moving contact, and contact is opened and closed, exempt to establish iron core and back-moving spring, after the closing of contact, exempt from for keeping electric current, energy savings not only, and can reduce the load of coil significantly, coil can be worked long hours do not generate heat or under the low-grade fever state, work, improved security performance and the sensitivity of contactor.
The present invention solves the technical measures that its technical problem takes, and electromagnet is established in the housing bottom left and right sides, the corresponding installation of the electromagnet of the left and right sides, and the housing left upper portion is fixed contact fixedly; Axis hole is established in middle and upper part at housing, axis hole is opened at the middle part of push rod, push rod is by in the axis hole that is pivotally mounted in housing, and the upper end of push rod arranges moving contact, establishes back cushion at the push rod at the moving contact back side, two blocks of magnet steel about install the lower end of push rod, the face tilt of the face of magnet steel and push rod during installation, when magnet steel and electromagnet in opposite directions near the time, the magnet steel face is relative with the facial plane of electromagnet, under the effect of the magnetic line of force, magnet steel and electromagnet keep the state of mutual adhesive; Snak link is established on top at the push rod axis hole, and below push rod and axis hole vertical line, snak link is established in the bottom of housing, and one on spring hangs on the snak link on push rod top, and the other end of spring hangs on the snak link of housing bottom.In the time of need cutting off the electricity supply, the electromagnet on housing right side is connected power supply, electromagnet produces the magnetic field identical with magnet steel polarity immediately, simultaneously, the electromagnet in housing left side is also connected power supply, the opposite polarity magnetic field of magnet steel on its generation and the push rod, about two electromagnet produce simultaneously the magnet steel right side pushed away the magnetic field that inhale on a left side, at this moment the force of spring on push rod is along with the motion of push rod is mobile to the right, effect lower push-rod at magnetic force and spring force turns right around pivot, left side magnet steel moment is close to the electromagnet in housing left side, and maintenance attracts state mutually under the effect in magnetic field, lean against on the housing of right side up to the back cushion on the push rod and to end, but the magnet steel face does not contact and leave the gap with the face of electromagnet, the while moving contact separates along with the motion of push rod, cut off the electricity supply, at this moment two electromagnet power supplies cut off about, and electromagnet loss of excitation, moving contact rely on the magnetic force of spring force and magnet steel to be fixed on the position of opening a sluice gate.When needing closed power supply, the electromagnet energize in housing left side, electromagnet produces the magnetic field identical with magnet steel polarity immediately, when the electromagnet in housing left side is connected power supply, the electromagnet on housing right side is also connected power supply, the opposite polarity magnetic field of magnet steel on its generation and the push rod, at this moment right magnet steel moment is close to the electromagnet on housing right side on the push rod, and under the effect in magnetic field, become adhesive situation, moving contact along with the motion of push rod moment closure, moving contact is connected power supply, at this moment two electromagnet power supplies cut off about, and electromagnet loss of excitation, moving contact rely on the magnetic force of spring force and magnet steel to be fixed on the position of closing lock, but the magnet steel face does not contact and leaves the gap with the face of electromagnet, avoids bump to damage.Such contactor does not need to keep electric current, and is energy-conservation, not only reduced the load of coil, coil do not generated heat or low-grade fever, and do not establish iron core, reduced the member link, thereby reaches the security performance of raising contactor and the purpose of sensitivity.
The invention has the beneficial effects as follows, energy-conservation, safety, simple in structure.
