Abstract
The utility model relates to an electronic switching device, in particular to an apparatus isolation switch with effective anti-lightening and electrical conservation. The apparatus isolation device mainly includes a body support plate, a transmission mechanism and a motor. The body support plate is provided with the motor, the transmission mechanism and a defined switch for defining the distance of on-switch contact, the motor and the transmission mechanism are communicated , the on-switch contact is located on the transmission mechanism and move with the transmission mechanism towards the direction of the off-switch contact, the off-switch is fixed on the body support plate or the shell, the on-switch contact and the off-switch contact achieve the miscommunication and closure through relative movement, and the transmission mechanism can be gear, banded horizontal gear mechanism, or chain mechanism.
Description
Technical field
The utility model relates to a kind of electronic switching device, especially a kind of can be effectively anti-lightning strike and the electrical equipment isolating switch of saves energy.
Background technology
Along with popularizing of electrical equipment, safety utilization of electric power, lightning protection and saves energy are the important topics that needs to be resolved hurrily at present, for adaptive technique updates and networked growth requirement, appliance manufacturers has been developed remote control switch, has been continued various idle functions such as numeral shows, lasting digital demonstration, WOL, timing switch, these functions provide in a large number simultaneously easily for the user, also bury many potential safety hazards and cause a large amount of energy wastes to the user.The remote control switch of electrical equipment has Pause key as in the remote control switch of television set, suspend the back power supply and still connect, and can open this switch with remote controller, wakes television operations up, and consume electric power.Must the closing television dynamo-electric source switch of cutting off the electricity supply, but this moment, television power-line still was communicated with power supply circuits, if have thunderbolt, high-tension current to seal in still can to puncture television set, have only plug pulled out to prevent to respond to thunder effectively and the circuit pulse damages television set.Simultaneously, the work of need switching on when the supply load electricity consumption of the relay contact control system of present most control circuits causes a large amount of waste of energy.
Summary of the invention
The purpose of this utility model is to avoid above-mentioned weak point of the prior art and a kind of electrical equipment isolating switch that can effectively cut off power supply is provided.The main part of this electrical equipment isolating switch is body supporting bracket, transmission mechanism and motor, motor, transmission mechanism are arranged on the body supporting bracket and be used to limit the qualification switch that moves the switch contact stroke, motor links to each other with transmission mechanism, moving switch contact is positioned on the transmission mechanism and can moves to deciding the switch contact direction with transmission mechanism, decide switch contact and be fixed on body supporting bracket or the housing, move switch contact and decide and realize that by carrying out relative motion the disconnection of contact is with closed between the switch contact; Transmission mechanism can be gear, banded flat toothed mechanism, also can be link chain mechanism.The utlity model has following beneficial effect: effectively carry out isolated from power, keep safe break distance, prevent thunderbolt, saves energy.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and concrete execution mode essentiality content of the present utility model is described in further detail.
Shown in the adjoint, the main part of this electrical equipment isolating switch is body supporting bracket 6, transmission mechanism 5 and motor 4, motor 4, transmission mechanism 5 are arranged on the body supporting bracket 6 and be used to limit the qualification switch 3 that moves switch contact 2 strokes, motor 4 links to each other with transmission mechanism 5, moving switch contact 2 is positioned on the transmission mechanism 5 and can moves to deciding switch contact 1 direction with transmission mechanism 5, decide switch contact 1 and be fixed on the body supporting bracket 6, move switch contact 2 and decide and realize that by carrying out relative motion the disconnection of contact is with closed between the switch contact 1.Transmission mechanism 5 is gear 7, banded flat tooth 8 mechanisms.During work, when being under the power-off state, motor 4 is received work order need carry out switch closure, motor 4 action this moment and the moving switch contact 2 that drives on the transmission mechanism 5 move to decide switch contact 1 along body supporting bracket 6, until moving switch contact 2 with decide switch contact 1 and contact the realization switch closure; Vice versa, motor 4 is received work order need carry out switch when disconnecting, motor 4 action and drive moving switch contact 2 on the transmission mechanism 5 along body supporting bracket 6 towards decide switch contact 1 counter motion, until moving switch contact 2 and decide switch contact 1 realization switch and disconnect fully.Under the situation of ac dump, also have the harm of being struck by lightning as colour TV, have only remote disconnection could effectively isolate thunder and lightning.This switch makes electrical appliance isolate civil power fully by remote motion, thoroughly eliminate because of electrical appliance charged due to the unsafe factor of electrical fire.As the spike absorber element being housed in the civil power side, lightning induction pulse and electrical network surge voltage are effectively absorbed land, greatly improved the safe in utilization of electrical appliance.Simultaneously, finish the work of suffered instruction when motor after, enter not electriferous state immediately.Be subjected to the support of motor and transmission mechanism, the contact reliably is switched on or switched off.When this switch is used for the relay contact control system of some control circuit, can realize that the relay contact control system need not energising work when the supply load electricity consumption, thus saves energy.
Claims (2)
1. electrical equipment isolating switch, major part is the body supporting bracket, transmission mechanism and motor, it is characterized in that: motor (4) is arranged on the body supporting bracket (6), transmission mechanism (5) and be used to limit the qualification switch (3) of moving switch contact (2) stroke, motor (4) links to each other with transmission mechanism (5), moving switch contact (2) is positioned at transmission mechanism (5) and goes up also and can move to deciding switch contact (1) direction with transmission mechanism (5), decide switch contact (1) and be fixed on body supporting bracket (6) or the housing, move switch contact (2) and decide and realize that by carrying out relative motion the disconnection of contact is with closed between the switch contact (1).
