Abstract
The utility model discloses a power supply breaker for a remote control colour television, which comprises a television. The utility model is characterized in that double button switches, a bridge rectifier and a contactor are connected to both ends of the television; the contactor is composed of a glass pipe, a coil, a static iron core, a movable iron core, an outer magnetic screen soft iron sheet, movable contacts, static contacts, etc. The utility model can automatically cut current to protect the television under the state that the television is shut down at definite time or in a remote control mode, and the current leads to the television. The utility model avoids problems generated when users are sleepy or tired and are reluctant to get up to pull a power supply. The utility model has the advantages of simple structure, low cost and low power consumption, and is also suitable for old people and disabled people.
Description
The utility model relates to power-supply device, especially relates to a kind of remote control colour TV set dump device.
Existing most of colour TVs all possess regularly or the remote-control closedown function on the market, but can not cut off the electric current in the machine, after the user presses timing or remote-control closedown key, the part components and parts are still in running order in the television set, this function of long-time use can cause these components and parts accelerated ageings, and consumed power; When these components and parts break down or external circuit have a power failure after incoming call or the late into the night during overtension again, just may occur that short circuit punctures fuse or components and parts are smoldered, on fire even cause that colour TV explodes, and causes unnecessary loss.
The purpose of this utility model provide a kind of can be regularly or can cut off the remote control colour TV set dump device of electric current in the machine behind the remote-control closedown automatically at television set.
The purpose of this utility model is to realize like this.The utility model comprises television set, feature is the two ends that two moving contacts of the switch of contactor connect attaching plug, a fixed contact connects an input of bridge rectifier, another fixed contact and another input that connects bridge rectifier after television set is connected, the two ends of the coil in two output termination contactors of bridge rectifier, the two ends of button biswitch are attempted by the two ends of moving contact, fixed contact respectively; Contactor is made up of two ends colyliform projection glass tube, coil, static iron core, moving iron core, external magnetism shielding soft iron sheet, fixed contact, moving contact, the rear end is equipped with static iron core in glass tube, at the glass tube Inner Front End moving iron core is installed, the glass tube outer wall is wound with coil, outside glass tube and coil, be surrounded by external magnetism shielding soft iron sheet, outside moving iron core, be fixed with two pairs of moving contacts and fixed contact respectively.
The end in opposite directions of the static iron core in glass tube, moving iron core posts one deck inner magnetic screen soft iron sheet respectively.
The utility model is because design has contactor; it can cut off the electric current that leads in the machine automatically under the state of television set timing or remote-control closedown; play the effect of protection television set; and saving electric energy; the problem that also can avoid the user to be reluctant to leave the bed and to start to pull out power supply and may occur under the dense or tired situation of sleepiness, not nimble old man, the disabled person of trick is especially suitable.The utility model both can be used as the television set private jack and had been fixed on the original socket position, replace original socket, also can insert on the existing socket and use, it is when using with 21 cun colour TV series connection of 70W, about 2 volts of voltage drop, power consumption has only 0.7W, so it has advantage simple in structure, with low cost, little power consumption.
