SWITCH FOR PREVENTION OF INRUSH CURRENT SHOCK AND CUT-OFF STANDBY POWER WITH ROTATION DELAY UNIT.

The present invention relates to a switch for preventing inrush current shock and blocking standby power constituting a rotary delay unit, and more particularly, a rotation delay unit such as a cylindrical or cylindrical shape in a switch for preventing inrush current shock and blocking standby power. After the external power is first applied to the internal circuit of the electronic product, the delay time is delayed until the unit rotates to activate the activation switch, and the electronic product is changed without changing the power supply mechanism of the existing electrical and electronic products. Prevents inrush current shock by constituting a rotating delay unit that effectively prevents damage, malfunction, deterioration of electrical quality, etc. by turning off the electric shock and turns off the standby power effectively when the electronic product is turned off. And a switch for shutting off standby power.

In general, a transient phenomenon occurs in which a current higher than the normal current flows at the instant of power supply to a distribution circuit or an electric device. This is called an inrush current.

In this inrush current, the "Hot Load Current" generated in the first stage is generated several times or several times at the same time as the power is turned on, which causes deterioration of the power distribution equipment, deterioration of performance, inability to cooperate with protection, and even deterioration in the quality of electronic products. Will result.

The “Hot Load Current” generated by the first stage of inrush current is the initial inrush current generated immediately after the line is input, the magnetization current of a device with an iron core such as a transformer motor, or a current for raising the temperature of an incandescent bulb. It has a very large value, more than double, but its duration is short-term, such as a few Hz.

Although NTC thermistors are used to reduce the electrical shock of inrush current, which affects the current electronic products, NTC thermistors are not capable of dissipating heat and do not function as they should if heat is not dissipated. As the heat is lost to the surroundings, the space containing other semiconductor components is heated, and the problem of the embedded environment is exacerbated.

On the other hand, in general, in the use of electronic products such as home appliances, office equipment, industrial equipment, energy consumption due to standby power is known to be considerable.

For example, in Korea, standby power consumption is known to reach 11% of the total consumption per household (306kWh). If this is expanded to 15 million households, energy of 520 billion won is consumed every year due to standby power.

The most effective way to prevent such standby power is to separate the power input from the outside (usually by plugging the plug into the wall outlet) (that is, the plug from the outlet). Was not effective due to user inconvenience.

In addition, various automatic or manual taps using a contact switch have been proposed and used, but there is a problem in that a switch of a power strip and an electronic product is dually operated when power is supplied.

On the other hand, in order to solve the above problems, the present inventor has proposed a "switch for preventing the inrush current shock and standby power" of the Republic of Korea Patent Registration No. 10-1057958 filed and registered.

However, the technique is delayed for a predetermined time by the delay unit 50, the predetermined time should be adjusted by the elasticity of the spring (34a) and the spring (S) of the red portion of FIG.

Therefore, the operation of adjusting the elasticity of the spring in order to delay for a predetermined time can not only be made by hand, it has to go through a separate process for performing this operation, which provides a problem of increasing the production time and labor costs.

In order to solve this problem, in the present invention, a delay unit constituting a rotating body such as a cylinder or a cylinder is started to delay the time during which the rotating body rotates (the time until the guide protrusion contacts the activation switch).

The unit 50 may be configured to be applied to an electronic product without changing the power supply mechanism of the existing electronic product. When the power of the electronic product is turned on, the inrush current causes direct damage or malfunction to the transformer or the component. This effectively prevents unwanted power, and turning off the electronics can effectively cut off unnecessary standby power.

Or an electromagnet 48 operated by the controller 80 is installed.

At this time, the electromagnet 48 is configured by winding the solenoid coil to the bobbin and connecting the solenoid coil terminal.

The controller 80 may be installed at a suitable position in the case 12. When the internal circuit 1 of the electronic product is turned off while the power is applied, the controller 80 controls and passes a current through the solenoid coil to generate a magnetic field in the electromagnet 48. To generate.

At this time, the electromagnet has the same polarity as that of the close contact magnet 46, so that the electromagnet 48 and the magnet 46 are pushed out to contact the first and second opening and closing terminals 23 and 25 and the first and second terminals. (22, 24) is to be opened (separated).

The electromagnet 48 then loses its magnetism because there is no power supply.

That is, the controller 80 is powered when the external power is applied to the internal circuit 1 by the power on unit 30 and the internal circuit 1 is deactivated or the control signal of the activation switch 70 (off signal). Is generated or the current flowing through the electronic product itself detects the current flowing through the electromagnet 48 to make the magnet 46 and generate the repulsive force so that the moving block 40 by the spring 34b As it returns to its original position, the contacts between the first and second opening and closing terminals 23 and 25 and the first and second terminals 22 and 24 are disconnected to cut off standby power.

In addition, the guide 51c is formed to protrude helically along the outer circumferential surface of the rotating body except for the portion where the guide groove is formed.

The number of guides and guide grooves can be changed as necessary. The guide grooves are configured to be inclined at one end thereof so that the rotating body can be partially rotated as the on-button advances, or the on-button protrusion 32a is provided on the on-button. 5 is configured to rotate the rotating part so that one end of the actuating projection member is over the top of the guide when the on button is reversed.

That is, the guide groove is formed so as to rotate part of the rotating body by the on-button projection 32a formed on the on-button or on-button when the on-button is pressed so that one end of the actuating projection member is guided when the on-button returns to its original position. Over the top of the.

When one end of the actuating protrusion member 52 spans the guide, one end of the actuating protrusion member is pressed by the spring to rotate the rotating body.

At this time, when the guide protrusion 51d is formed to protrude to one end of the rotating body, when the rotating body rotates, the guide protrusion also rotates at the same time.

That is, when the on button returns to its original position, the actuating protrusion member is caught over the top of the guide to press the guide to rotate the rotating body, and the guide protrusion formed at one end of the rotating body rotates to operate the activation switch as shown in FIG. 9. It is to be made.
