Abstract
The new-type piezoelectric ceramic relay comprises a shell, the inner and matched outer contacts in the shell, a reset mechanism arranged between the contacts, and a piezoelectric ceramic control mechanism with the piezoelectric ceramics and a fixed base connected with shell. Wherein, arranging the center of the ceramics on the base, connecting the pivot point end to the shell, setting an insulation joint with the former inner contact on the active end of the ceramics. This invention needs low power consumption, and introduces no interference.
Description
(1) technical field
The present invention relates to a kind of relay.
(2) background technology
Existing relay all is that solenoid produces magnetic field under the effect of electric current to the perfectly straight stream electric current of solenoid, and contact is connected, and makes circuit turn-on, does not pass through when solenoid has electric current, and contact rebounds under elastic reaction, and circuit disconnects.The defective that above-mentioned relay exists is: 1, electromagnet is by coil is filled direct current, and coil produces magnetic field under the effect of electric current, this mode charging current according to the difference of load from tens mA to hundreds of mA, power consumption is bigger.2, coil has big back electromotive force that circuit is produced great impact at interdischarge interval, causes interference easily, makes the circuit instability, produces misoperation.3, because the solenoid actuated power consumption is bigger, make temperature higher, make material deformation even quick aging easily.
(3) summary of the invention
In order to overcome the deficiency that existing relay power consumption causes interference greatly, easily, the invention provides a kind of low in energy consumption, novel piezoelectric ceramic type relay that can not cause interference.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of novel piezoelectric ceramic type relay, comprise housing, be installed in the interior contact that cooperatively interacts in the housing, outer contact, in described, be provided with resetting device between the outer contact, the contact is connected with the piezoelectric ceramic controlling organization in described, described piezoelectric ceramic controlling organization comprises piezoelectric ceramic, holder, holder is fixedlyed connected with housing, the middle part of piezoelectric ceramic is installed on the holder, the support end of piezoelectric ceramic is fixedlyed connected with housing, the movable end of piezoelectric ceramic is provided with the insulation connector, contact in installing on the described insulation connector, described outer contact is installed on the housing.
Further, the both sides up and down of described insulation connector are equipped with interior contact, the outer contact that the installation up and down in the housing cooperates with two interior contacts.
Further again, described fixed seating is in the support end place near piezoelectric ceramic.
Further, described resetting device is an elastic insulator.
Operation principle of the present invention is: when piezoelectric ceramic is applied in suitable voltage, produce little distortion, produce certain power (size of power is directly proportional with the voltage that applies) simultaneously, the contact is done offset movement and (is provided with gap or directly connection between interior contact and the piezoelectric ceramic controlling organization in driving, when piezoelectric ceramic is switched on, come in contact with interior contact, make it to outer contact generation strain), the contact produces with outer contact and effectively contacts in making, circuit turn-on is not when piezoelectric ceramic applies voltage, do not produce distortion, the power that produces disappears simultaneously, and piezoelectric ceramic is got back to initial position under the effect of resetting device, and circuit is disconnected.Can design the relay of single channel, also can make the relay of two-way, as long as add two contacts and a resetting device, as long as pass to the break-make that reverse voltage can be realized the opposite side circuit at the opposite side of piezoelectric ceramic.
Beneficial effect of the present invention mainly shows: 1, piezoelectric ceramic has energy consumption low (having only several milliamperes), cuts down the consumption of energy greatly.2, solenoid has big back electromotive force that circuit is produced great impact when relieving and closure, causes interference easily, makes the circuit instability, produces misoperation, and piezoelectric ceramic can not produce back electromotive force, thereby can not cause interference to circuit.3, because the solenoid power consumption is bigger, and heat dissipation capacity is big, need to consider heat dissipation problem, and that piezoelectric ceramic consumes altogether is low, need not considers this problem.4, response speed is fast.

(5) embodiment
Below in conjunction with accompanying drawing the present invention is further described.
With reference to Fig. 1, Fig. 2, Fig. 3, a kind of novel piezoelectric ceramic type relay, comprise housing 1, be installed in the interior contact 4 that cooperatively interacts in the housing, outer contact 5, in described, outer contact 4, be provided with resetting device between 5, contact 4 is connected with the piezoelectric ceramic controlling organization in described, described piezoelectric ceramic controlling organization comprises piezoelectric ceramic 2, holder 9, holder 9 is fixedlyed connected with housing 1, the middle part of piezoelectric ceramic 2 is installed on the holder 9, the support end of piezoelectric ceramic 2 is fixedlyed connected with housing 1, the movable end of piezoelectric ceramic 2 is provided with insulation connector 3, contact 4 in installing on the described insulation connector 3, and described outer contact 5 is installed on the housing.
Described holder 9 is positioned at the support end place near piezoelectric ceramic.Described resetting device is an elastic insulator 6, and elastic insulator 6 is fixedlyed connected with inside and outside contact 4,5 by bolt 8.
The course of work of present embodiment is: when piezoelectric ceramic 2 does not apply voltage, do not produce distortion, the power of generation disappears simultaneously, and piezoelectric ceramic 2 is got back to initial position under the effect of elastic insulator 6, and circuit is disconnected.When piezoelectric ceramic 2 is applied in suitable voltage, produce little distortion, produce certain power (size of power is directly proportional with the voltage that applies) simultaneously, offset movement is done in contact 4 in driving, and contact 4 produces with outer contact 5 and effectively contacts circuit turn-on in making.
The both sides up and down of the insulation connector 3 of present embodiment are equipped with interior contact, the outer contact that the installation up and down in the housing cooperates with two interior contacts.All the other structures are identical with embodiment 1.
The course of work of present embodiment is identical with embodiment 1, enables another to the contact if desired, can realize another break-make to the contact as long as pass to reverse voltage.
