Abstract
The utility model relates to an electromagnetic relay which is designed for the energy saving. A control circuit which is composed of a capacitor and a current amplifier is connected in a coil circuit in series. A permanent magnet and a moving contact are fixed on a swing plate which can deflect, and the top end of the swing plate is hung on a coil brace through a spring. The permanent magnet is sucked by an iron core when the electricity is connected. The swing plate is deflected to one side of a coil, and the capacity is charged to maintain the tiny attracting holding current. The capacitor is discharged when the electricity is disconnected. The iron core instantly and reversely magnetized to repel the permanent magnet, and the swing plate is swung to the other side. The double-surface moving contact on the swing plate is in short connection with a static contact following the swing. The energy saving effect is obvious under the attracting working condition in a long time.
Description
The utility model relates to a kind of electromagnetic relay, relates to a kind of energy-saving electromagnetic relay or rather.
When the solenoid of electromagnetic relay passes through electric current, electromagnet produces suction and inhales moving armature, be transferred to contact component, make the contact action, keep adhesive and will keep normal power-up, be 110mA as JQX-10 type electromagnetic relay attract current and adhesive holding current, be in the electromagnetic relay of attracting state work for a long time for those, more as lathe power consumption with electromagnetic relay, electromagnetic relay is converted into mechanical energy in order to offset the active force of back-moving spring in the relay with electric energy in addition, also is a kind of energy consumption of waste.
The purpose of this utility model is that existing electromagnetic relay structure is made improvements, and designs a kind of energy-saving electromagnetic relay, has the little characteristics of adhesive holding current, is particularly suited for long-term adhesive work to use, and has remarkable energy saving effect.
Energy-saving electromagnetic relay of the present utility model comprises solenoid, coil brace, and permanent magnet, contact component and spring by fixed contact, moving contact are formed is characterized in that:
1) is serially connected with the control circuit of forming by electric capacity and triode current amplification circuit in the described solenoid loop;
2) but have upright installation, with the deflection bottom the swing fulcrum make double-swing deflection oscillating deck, described permanent magnet is fixed on position on the upper side, oscillating deck center, described moving contact is fixed on oscillating deck bottom position place, but described coil brace top is by the described spring deflection oscillating deck that is hung.
The electromagnetic relay of this improvement structure has bigger attract current in coil electricity moment, produce magnetic field and make iron core magnetization adhesive permanent magnet, but the deflection oscillating deck thereupon deflection coil on one side, moving contact and fixed contact short circuit on one side.Along with the charging to polyphone electric capacity in the loop, its terminal voltage rises, and the adhesive holding current reduces to very little in the loop, but moving contact still remains on above-mentioned attracting state, is energy conservation.During the control circuit outage, the storage capacitor discharge, by reverse current, oscillating deck is repelled in iron core moment magnetic reversal in the coil, but make permanent magnet can break away from iron core easily with a swing point location, top by the deflection swing chip architecture that spring is hung, but the deflection of deflection oscillating deck is in the another location.The swing sheet is made bidirectional swinging with swing fulcrum of its deflection bottom, the two-sided contact on it respectively with two single face fixed contact short circuits, realize two kinds of contact conditions of relay contact.
Because the adhesive holding current is little, but and deflection swing chip architecture light and handy, spring force is little, thereby the energy utilization rate height.
Describe technology of the present utility model in detail below in conjunction with the embodiment accompanying drawing, embodiment is with the improvement structure explanation of JQX-10 type electromagnetic relay.
Accompanying drawing 1 solenoid controlled circuit theory diagrams
Each parts plane distribution schematic diagram of accompanying drawing 2 energy-saving electromagnetic relays
But the structural representation of accompanying drawing 3 energy-saving electromagnetic relay deflections swing sheet
Referring to accompanying drawing 1, AC-input voltage is through the D1-D4 rectification, and output connects the current amplification circuit of being made up of T1, T2 compound transistor etc., and coil L and capacitor C are connected in the CE loop of T2.When power supply was arranged, T1, T2 conducting had electric current among the coil L, simultaneously capacitor C are charged.Along with the C both end voltage raises, loop current is almost 0, enters the adhesive hold mode.Experiment shows, the JQX-10 type electromagnetic relay before and after improving, and its attract current is 110mA, but the adhesive holding current is reduced to 0.035mA by 110mA.During outage, T1, T2 end, storage capacitor C discharge, and moment is by reverse current, core magnetic pole instantaneous variation among the coil L.
Referring to accompanying drawing 2, be distributed with control circuit board 1 on the relay base 10, circuit production shown in Figure 1 is on circuit board 1, coil brace 2 is the ㄈ type, solenoid 3 is fixed in the support 2, is fixed on the stationary contact bracket 41,42 on the base 10, and two single face fixed contacts are respectively arranged on it.But 5 is deflection swing sheet, uprightly be installed in by the iron-core coil, center position mounting permanent magnet 6 on the upper side on the plate, the lower end of swing sheet 5 has two-sided moving contact to stretch on the stationary contact bracket 41,42 between two single face fixed contacts, ㄈ type cantilever tip has screw 7, spring 8 one end hooks are on screw 7, and the other end is positioned at the upper end of swing sheet 5.The swing sheet 5 the lower end by screw be positioned at ㄈ type support 2 the lower end and as the swing fulcrum.When the iron core of coil 3 (invisible among the figure) attracts on the swing sheet permanent magnet 6, swing sheet 5 partially on one side at coil brace, its moving contact and side's fixed contact short circuit.When iron core discharged permanent magnet, the swing sheet turned to and departs from support on one side, its moving contact and the opposing party's fixed contact short circuit, and the deflection angle of swing sheet is limited, and can be subjected to the restriction of spring 8.
Referring to accompanying drawing 3, swing sheet 5, the center is position mounting permanent magnet 6 on the upper side, and two-sided moving contact 51,52 is arranged on the extension of lower end, stretches between two single face fixed contacts of stationary contact bracket 41,42 among Fig. 2.Two rectangular preiections 21,22 of coil brace bottom are embedded in swing both sides, the sheet 5 lower end breach 53,54, and swing sheet 5 is positioned at the coil brace lower end by screw 9, form the see-saw structure of swing fulcrum secundly.There is screw 7 the coil brace upper end, and spring 8 one end hooks are lived screw 7, and the other end is enclosed within on the swing sheet 5.
Energy-saving electromagnetic relay of the present utility model has remarkable energy saving effect through on probation on lathe, and simple in structure, reliable in action.
