Abstract

The utility model relates to an energy saving permanent magnet relay which is formed by the assembly and the connection of a permanent magnet, a fixed conducting magnet, a moving conducting magnet, a magnetic conductor, a coil, a moving contact mechanism, a static contact mechanism, a guide rail, a connecting rod and a casing. The position connecting relationship of the utility model is that the fixed conducting magnet is closely contacted and connected with the permanent magnet; the permanent magnet is closely contacted and connected with the magnetic conductor; the magnetic conductor is contacted and connected with the moving conducting magnet in the mode of slide; the left end and the right end of the magnetic conductor and the left end and the right end of the moving conducting magnet can freely swing up and down; the other end of the moving conducting magnet is hung in the air to be switched off. When one end of the moving conducting magnet is connected with the connecting rod in the mode of slide; the connecting rod is connected with the moving contact mechanism in the mode of slide; the moving contact mechanism is confined to move up and down within a perpendicular range by the guide rail; when an upper contact point in the static contact mechanism is switched on, a lower contact point is in the state of switching off; when the lower contact point is switched on, the upper contact point in the static contact mechanism is in the state of switching off. The proposal of the utility model is that electromagnetism is converted into mechanical motion; the utility model can be popularized to wide power fields to make a plurality of power machines improved. The relay has the advantages of less energy consumption, no noise, no oscillation phenomenon of the contact mechanisms, no ignition, less possibility of damage and longer service life.

Description

Energy-saving permanent-magnet relay

(1) technical field:

The utility model is an energy-saving permanent-magnet relay, belongs to electric equipment products.

(2) background technology:

Existing various types of relay---as alternating-current trigger, magnetic starter etc., when operation, all must there be electric current to pass through coil, therefore, all want the more electric energy of loss and all can produce low frequency (100Hz) noise, the contact mechanism of relay all has microvibration, make the contact be easy to sparking and damage, the life-span short or work unreliable.

(3) summary of the invention:

The purpose of this utility model be exactly for overcome and solve existing relay exist power consumption many, produce that noise, contact mechanism easily vibrate, easily sparking damages, work is unreliable, the shortcoming and the problem of life-span weak point etc., research and design is a kind of except that the few electric energy of need consumption in the node switching process, at work not power consumption fully in service, noiselessness, contact mechanism friction phenomenon, the energy-saving permanent-magnet relay not fragile, the life-span speciality of dying.

The utility model is realized by following technical proposals: the structure of energy-saving permanent-magnet relay and course of work schematic diagram are as shown in Figure 1, it is by permanent magnet 1, fixedly magnetic conduction iron 2, motion magnetic conduction iron 3, magnetic conductor 4, coil 5, moving contact mechanism 6, fixed contact mechanism 7, guide rail 8, connecting rod 9, shell 10 mutual group loads connect and constitute, and its mutual rigging position and annexation are: by the superimposed fixedly magnetic conduction iron 2 that constitutes of silicon steel sheet and permanent magnet 1 mutually closely contact connect; Permanent magnet 1 closely contacts with the magnetic conductor of being made by ferromagnetic material 4 and is connected; Magnetic conductor 4 be slidably to contact to be connected by the superimposed motion magnetic conduction iron of making 3 of silicon steel sheet, two ends, the left and right sides can arbitrarily swing up and down; Motion magnetic conduction iron 3 when an end and connecting rod 9 are slidingly connected, the just unsettled disconnection of the other end; Connecting rod 9 is slidingly connected for 6 one-tenth with moving contact mechanism; Moving contact mechanism 6 is limited in the vertical scope by guide rail 8 and moves up and down; When the upper contact of rest(ing) contact mechanism 7 was connected, the lower contact of fixed contact 7 mechanisms just was in off-state, otherwise promptly right; Whole permanent-magnet relay mechanism is installed in the shell 10, and the power supply lead wire of coil is drawn by the wire guide of reserving on the shell 10.

The operation principle of this energy-conservation permanent-magnet relay is as follows: its key is " electromagnetism and permanent-magnetic field interact ", specifically: permanent magnet 1 constitutes the closed-loop path by magnetic circuit A, makes motion magnetic conduction iron 3 the right tightly constitute a kind of steady state of motion with fixing magnetic conduction iron 2 is tightly closed; This moment, motion magnetic conduction iron 3 left sides were by magnetic circuit B, because of the excessive magnetic field intensity of air gap a little less than, be in the bigger position of fracture always; When need switching node state, only need to give coil 5 instantaneous energisings to produce additional magnetic circuit C, magnetic circuit C and magnetic circuit A are cancelled out each other, make the right field weakening, and magnetic circuit C and magnetic circuit B addition make magnetic field, the left side obtain bigger reinforcement, so motion magnetic conduction iron 3 left side closures, the right is left and is formed a fracture, and at this moment additional power source disconnects, just is in another steady-working state again.

The utility model is compared with existing relay has following advantage and beneficial effect: (1) the utility model is to become mechanical movement by electromagnetism, utilize principle of the present utility model, can be generalized to the power field very widely that is applied to, it can make a lot of dynamic power machines be improved, therefore has tangible creativeness, outstanding advantage is compared with prior art arranged, bigger breakthrough is arranged, very considerable economic and social benefit is arranged; (2) this energy-conservation permanent-magnet relay removes in its node transfer process, and coil need power up, and needs outside the loss energy seldom, in the work running, additional power source can be removed fully, but this energy-conservation permanent-magnet relay safe and reliable operation still; (3) has no noise in this energy-conservation permanent-magnet relay work running; (4) contact mechanism of this energy-conservation permanent-magnet relay does not have no oscillation phenomenon, and is therefore fragile, the life-span is longer.

(4) description of drawings:

Below Figure of description is further specified as follows: Fig. 1 is that the structure of this energy-conservation permanent-magnet relay constitutes and course of work schematic diagram.Among the figure: the 1st, permanent magnet, the 2nd, fixing magnetic conduction iron, the 3rd, motion magnetic conduction iron, the 4th, magnetic conductor, the 5th, coil, the 6th, moving contact mechanism, the 7th, fixed contact mechanism, the 8th, guide rail, the 9th, connecting rod, the 10th, shell.

(5) concrete execution mode:

The applicant thinks and realizes that optimal way of the present utility model can be as follows: (1) by shown in Figure 1, design, processing and manufacturing or choose each parts, and for example: permanent magnet 1 can be selected Nd-Fe-B permanent magnetic material type for use; Fixedly magnetic conduction iron 2 can select that 0.5 silicon steel sheet is folded to be made for use; Motion magnetic conduction iron 3 can select for use the superimposed compacting of silicon steel sheet and all-purpose adhesive or epoxy resin to form, and specification can be 0.5 silicon steel sheet; The magnetic conductor 4 optional electrical pure irons of using; Coil 5 is optional to be made skeleton with bakelite or engineering plastics and forms with the copper wire coiling that is coated with insulating varnish outward; Moving contact mechanism 6, fixed contact mechanism 7, guide rail 8, connecting rod 9 all can be ordered by relay manufacturer and close the ready-made parts of specification, and shell 10 is optional injection molded with engineering plastics.The technical indicator parameter that certain whole energy-saving permanent-magnet relay can propose to be correlated with,, order customized to existing relay manufacturer.
