Two are entered the below that electric connecting terminals 24 is positioned at the copper conductive plate 233 of electric connecting terminals; Respectively enter electric connecting terminals 24 and comprise a sheet metal frame 241, steel adjustment screw 242 and copper static contact panel 243, the diapire of metal frame is provided with the adjustment screw 244 with adjustment screw adaptation; Static contact panel comprise level along the longitudinal direction establish extend to form tension disc portion 2431, from front end, tension disc portion upwards vertical bending extend to form connecting plate portion 2432, from top, connecting plate portion backward horizontal bending extend to form corbel back slab portion 2433, from rear end, corbel back slab portion the upwards fixed contact support sector 2434 that extends to form of vertical bending, this fixed contact support sector is provided with the fixed contact 2435 with a corresponding moving contact adaptation; The roof of described sheet metal frame 241 between tension disc portion 2431 and corbel back slab portion 2433, and is positioned at the rear side in connecting plate portion 2432.
Each ejector pin component 26 comprises support spring 261 and insulation fore-set 262; Support spring is positioned within the spacing blind hole 273 of thimble pedestal, the front end of going up along the longitudinal direction of insulation fore-set 262 is arranged in the spacing blind hole of thimble pedestal, and be crimped on support spring, the spacing blind hole of thimble pedestal is stretched out in the rear end of insulation fore-set, apical grafting is on the U-shaped inwall of a corresponding U-shaped movable contact spring, and the rotation of U-shaped movable contact spring is met electroplax portion be crimped on out in the rotation support sector of conductive plate in electric connecting terminals, the rotation support sector making the rotation of U-shaped movable contact spring connect electroplax portion and conductive plate forms stable electrical connection.
When seesaw button 3 back and forth shakes, drive ejector pin component back and forth to shake by button base, thus back and forth stir adaptive U-shaped movable contact spring.When U-shaped movable contact spring rotates, moving contact 253 rotates until be crimped on the adaptive fixed contact 2435 entered in electric connecting terminals 24 thereupon, and now this enters electric connecting terminals and goes out the circuit turn-on between electric connecting terminals; When U-shaped movable contact spring upwards rotates, moving contact 253 leaves fixed contact 2435 thereupon rotating, and now this enters electric connecting terminals and the circuit gone out between electric connecting terminals disconnects.
Should the basic functional principle of seesaw button be driven by electromagnetic drive mechanism to be in use-case: when magnet exciting coil forward energising in electromagnetic driver, dynamic iron core is under the acting in conjunction of the electromagnetic force of magnet exciting coil and the absorption affinity of permanent magnet, overcome the reseting elasticity of back-moving spring and slippage forward, thus drive driving connecting rod to move forward certain distance by its drive plate portion, and then drive the first pole 513 to rotate backward around the shaft, thus stir the upper end of seesaw button; When the magnet exciting coil in electromagnetic driver is oppositely energized, dynamic iron core is under the acting in conjunction of the electromagnetic force of magnet exciting coil and the reseting elasticity of back-moving spring, overcome the absorption affinity of permanent magnet and slippage backward, thus drive driving connecting rod to move a certain distance backward by its drive plate portion, and then drive the second pole 513 to rotate backward around the shaft, thus stir the lower end of seesaw button; Thus make drive rod in the process of rotating and reset, drive seesaw button back and forth to shake.
Positive effect should be had by use-case: (1) should the comparatively compact simplification of use-case structure, and manufacturing cost is comparatively cheap, can meet the automatic switchover of two-supply circuit in most cases.(2) should conventional wall wall type power switch can be replaced to use by use-case, the automatic switchover or the remote control that realize two-supply circuit switch, thus realize the intellectuality manipulation of household electric appliances and stable Energy control, be particularly useful for changing existing important department electric circuit.
(application examples 2)
Figure 27 shows the second embody rule mode of the present invention.
Should use-case be a kind of Long-distance Control power switch for switch cubicle adopting above-described embodiment 2 to make, substantially identical with application examples 1, difference is: as shown in Figure 27, should also comprise the manual-operating mechanism 6 back and forth shaken for manual actuation seesaw button by use-case.The manual-operating mechanism 6 of use-case should comprise two Manual press seesaws 61; The antetheca center of front stall is provided with square hole 43 along the longitudinal direction, and the inwall of front stall antetheca is provided with pivoted hole 44; Each Manual press seesaw 61 is provided with Manual press panel part 611, to the pivot joint rotating shaft 612 that pivoted hole 44 is rotationally connected, for being connected to the first manual lever 613 of a corresponding seesaw button upper end and the second manual lever 614 for being connected to this seesaw button lower end; Each Manual press panel part 611 is arranged in the square hole 43 of front stall antetheca, pivot joint rotating shaft 612 is arranged on the left and right sides of each Manual press panel part inwall, and be respectively plugged in a corresponding pivoted hole 44, thus each Manual press panel part back and forth can be shaken around pivot joint rotating shaft 612; In use-case, for increasing the intensity of the first manual lever and the second manual lever, should also be provided with the enhancing bar portion 615 for connecting the first manual lever and the second manual lever.From the side, the basic configuration that Manual press seesaw, the first manual lever, the second manual lever and enhancing bar portion 615 are combined to form is rectangle.
Should in use-case, in order to strengthen sensitivity level, the end, rear end of the first manual lever is provided with the first cylinder 616, the end, rear end of the second manual lever is provided with the second cylinder 617, in the reciprocal shake of seesaw button, first cylinder is connected to the upper end of seesaw button all the time, and the second cylinder is connected to the lower end of seesaw button all the time.Left and right is extended all in the horizontal direction for each first cylinder and the second cylinder, makes the first manual lever and the second manual lever and seesaw button form linear contact lay.
Should in use-case, each seesaw button abuts simultaneously and has the drive rod of an electromagnetic drive mechanism and the first manual lever of a Manual press seesaw and the second manual lever.
Should the course of work of use-case be: the pulling force that plug absorption armature overcomes extension spring makes it rotate, armature drives drive rod to rotate around the axis, stir seesaw button by the first bulbous protrusion 545 of the first pole, seesaw button drives Manual press seesaw to turn an angle by the second manual lever; When plug no longer adsorbs armature, extension spring band moving armature resets, armature and then drive drive rod rotate backward around the shaft to reset, now stir seesaw button by the second bulbous protrusion 546 of the second pole, and seesaw button drives Manual press seesaw homing by the first manual lever; Certainly, directly pressing Manual press seesaw also can be adopted to make its reciprocating rotation by force, seesaw button also can be driven back and forth to shake.
Should the advantage of use-case be can not only realize remote electric manipulation and automatically manipulate, can also realize switching manipulation by hand.
