The utility model has no need of sustaining the current, and has the advantages of electric energy saving, simple wire connection, safety and multiple control function. The utility model comprises a coil, an armature iron, and contacts. The utility model is characterized in thatthe center part is a ratchet wheel mechanism; the ratchet wheel has three layers; the upper and the lower two layers are used for controlling the connection and disconnection of the contacts; the middle level does stepping movement; one side of the ratchet wheel is provided with a push rod; one end of the push rod is connected with the armature iron; the other side of the ratchet wheel is provided with a braking and positioning ratchet pawl.

Description

A kind of multistable stepping relay of many controlled function

The utility model belongs to the stepping relay class, specifically a kind of multistable stepping relay of many controlled function.

General electromagnetic relay, behind coil electricity, output contact promptly responds input energizing quantity and the change state.After this, must there be certain electric current of keeping just can make relay continue to keep this state in the coil.Be lower than certain value when coil current is cut off or drops to, be after input energizing quantity is removed, output contact just returns to initial condition immediately.Therefore it is a kind of device with the work of monostable mode.

The purpose of this utility model is: the multistable stepping relay that provides a kind of and need not keep electric current, saves energy, wiring is simple, safe and reliable and has the various control function to the user.

Implementation of the present utility model is:

A kind of multistable stepping relay of many controlled function, comprise coil, armature, contact, it is characterized in that its core component is a ratchet mechanism, totally three layers on ratchet, the upper and lower two-layer break-make that is used for controlling the contact, step motion is made in the middle level, and a side of ratchet has push rod, push rod one end links to each other with armature, and the opposite side of ratchet has braking location ratchet.

The every energising of coil once, armature promptly drives push rod and promotes ratchet and change and move a step, and the contact is with regard to the response input energizing quantity and the change state, even and after input energizing quantity removes, the contact still can keep this state because of the positioning action of ratchet, switches on once more up to coil next time.The structure of conversion levels ratchet, be that upper strata ratchet ratchet number is any one in 3 and 6, lower floor's ratchet ratchet number also is any one in 3 and 6, and can form 1-2 contact, a 2-4 step preface is the different contact combinations of a circulation, forms series of products.The parameter of conversion coil can make the input voltage of product that plurality of specifications such as 12/24VDC, 12/24/36/48/110/230VAC are arranged, and forms series of products.The load current of relay output contact is 10A, can satisfy the requirement of general control circuit.

Because this relay is to be driven by of short duration current impulse of time, therefore can be referred to as the pulse control relay, again because it is to work, promptly have a plurality of stable states by the mode that 2-4 step preface is 1 circulation, add it and take stepper drive, therefore also can be described as the multistable stepping relay.

Below in conjunction with accompanying drawing the utility model is further described:

Relay mainly is made up of several parts such as coil, armature, ratchet mechanism and contact systems.See Fig. 1, wherein critical component is a ratchet mechanism.Ratchet has three layers, two-layer up and down disconnection or the closure that is used for controlling the contact, and the middle level is then made step motion and is played the role of positioning.After coil 1 energising, inhale moving armature 2, armature 2 drives push rod 4, promotes push rod 4 to left movement, makes ratchet 5 rotate counterclockwise a step.So ratchet 5 bilevel ratchets make two groups of contacts change state, or disconnect or closure.After the pulse current of coil disappeared, armature 2 set back because of the pulling force of spring 3, drives push rod 4 simultaneously and moves right.Because of stopping of braking location ratchet 6, ratchet 5 stands, push rod 4 is only return original position after ratchet surface is slided.Therefore till the contact is kept this state when coil 1 energising next time.

Conversion ratchet 5 bilevel ratchet structures, see Fig. 2, Fig. 3 and Fig. 5 can form 1-2 contact arranged, a 2-4 step preface is the contact combination sequence of 1 circulation, forms the series of products with different control functions of different model name, sees Table 1.For example " 01 " type is a single contact, 1 to open, 1 to close that totally 2 step prefaces are the contact system of 1 circulation; " 04 " type is a double-contact, 2 to open, 2 to close, 1 to open and 1 close, 1 close 1 and open that totally 4 step prefaces are the contact system of 1 circulation.

Table 1

Advantage of the present utility model is as follows:

1, simple, the economical with materials of wiring: traditional multiple control circuit is (with 1 of 2 above switch control Above load) needs to use one pole double-throw (SPDT) or double-pole double-throw (DPDT) switch and make With 3 lines or the wiring of 4 lines. The cross section of its all leads all should be selected by the size of load current. As use this instead Product is made control circuit, and the control line of coil and push button need only use 2 lines, and conductor cross-section is not more than 0.5mm²Just can use, it is simpler to connect up, greatly economical with materials.

2, saves energy, safe and reliable: because relay coil electric current pulsed drive need not to keep Electric current, therefore saves energy significantly, and eliminated unsafe hidden danger. This relay has 2 in use Plant connection. A kind of is the connection that same power supply is used in coil input voltage and load, sees Fig. 6. For the guarantor Body safety, this product specialized designs the low-voltage safety series of products, can use the 2nd kind of connection, i.e. coil electricity The connection that separate with load power source in the source is seen Fig. 7, can use 12/24V DC or 12/24 The power drives coil of/36/48V AC has guaranteed personal safety.

3, various control function, universal flexible: because this product has 1-2 contact, the break-make of contact has 2-4 kind state forms series of products, therefore can satisfy the needs of the multi-control function processed of user.

4, can realize the control of remote control and multiple spot. And can arbitrary extension.
