Abstract
The invention relates to the technical field of automatic control equipment, in particular to an automatic electromagnetic switch, which comprises a shell, a coil, a guide pipe, static contacts and an iron core, wherein the shell is of a cylindrical structure which is provided with a through hole at one end and the two static contacts at the other end; the coil is arranged in the shell; the guide pipe is arranged in the coil; the iron core is arranged in the guide pipe; the iron core is provided with a contact; and magnets are arranged on the shell. The iron core is respectively sucked with the upper magnet and the lower magnet when the iron core moves up and down and the positions are fixed, so that durable electrification is avoided and heating is reduced; and furthermore, the electric energy is saved and the stability of the switch is improved.
Description
Technical field
The present invention relates to the automatic control equipment technical field, especially a kind of automatic electromagnetic switch.
Background technology
Existing Vehicular starter electromagnetic switch mainly is made of shell, coil, guide pipe, fixed contact and iron core.Its effect is under the control of automobile key door, utilizes the elastic force of magnetic force that coil electricity produces and return spring to make iron core reciprocating motion in guide pipe finish the startup of starter and stop.Move when coil electricity produces the magnetic field suction iron core, and iron core will be rested on certain position, then need to continue energising to produce larger confining force, this not only wastes electric energy, and coil is overheated, can make operational failure.
Summary of the invention
Large in order to overcome existing electromagnetic switch power consumption, heating is high, and the deficiency of job insecurity the invention provides a kind of automatic electromagnetic switch.
The technical solution adopted for the present invention to solve the technical problems is: a kind of automatic electromagnetic switch, comprise shell, coil, guide pipe, fixed contact and iron core, shell is tubular, one end is provided with through hole, and the other end is provided with two fixed contacts, and coil is installed in the enclosure, guide pipe is installed in coil, iron core is installed in the guide pipe, and iron core is provided with contact, and shell is provided with magnet.
According to another embodiment of the invention, comprise that further contact is cylindrical, be positioned at the central authorities of iron core bottom.
According to another embodiment of the invention, comprise that further magnet has two, lay respectively at top and the bottom of outer casing inner wall.
According to another embodiment of the invention, comprise that further magnet is annular, on the push rod that is enclosed within iron core, another and contacts mates.
The invention has the beneficial effects as follows, establish magnet at the two ends of shell, when moving on the iron core, with upper magnet attraction, the fixed position, when iron core moves down and the lower magnet adhesive, lasting energising has been avoided in the fixed position, reduce heating, and saved electric energy, improved the stability of switch.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is structural representation of the present invention.
1. shells among the figure, 2. coil, 3. guide pipe, 4. fixed contact, 5. iron core, 7. contact, 8. magnet.
Embodiment
Structural representation of the present invention such as Fig. 1, a kind of safety electromagnetic switch, comprise shell 1, coil 2, guide pipe 3, fixed contact 4 and iron core 5, shell 1 is tubular, and an end has through hole, the other end is provided with two fixed contacts 4, coil 2 is installed in the shell 1, and guide pipe 3 is installed in the coil 2, and iron core 5 is installed in the guide pipe 3, iron core 5 is provided with contact 7, and shell 1 is provided with magnet 8.Contact 7 is cylindrical, is positioned at the central authorities of iron core 5 bottoms.Magnet 8 has two, lays respectively at top and the bottom of shell 1 inwall.Magnet 8 is annular, and on the push rod that is enclosed within iron core 5, another cooperates with contact 7.
During work, coil 2 energisings produce magnetic field, attract iron core 5 to move, when moving on the iron core 5, with magnet 8 adhesives at top, the fixed position just can cut off the power supply, then coil 2 is switched on and is produced the opposing magnetic field, attracts iron core 5 to move down, with bottom magnet 8 adhesives, the fixed position just can cut off the power supply, and contact 7 is connected with fixed contact 4, so repeatedly, do not continuing just to provide confining force in the situation of energising, thereby saved electric energy, reduced heating, improved the stability of switch.
