Abstract
The utility model relates to a relay type automatic power-off energy-saving switch, comprising a mechanical part and an electronic part. The main structure of the relay type automatic power-off energy-saving switch is that an ordinary pull switch is additionally provided with a transition contact piece, a fuse plug and a socket. Under a normal work state, once a line is suddenly in a power failure state, the relay type automatic power-off energy-saving switch automatically cuts off power, and even the power is supplied again, the relay type automatic power-off energy-saving switch is also in a power-off state no matter on which the switch stays. If needs switching on, the relay type automatic power-off energy-saving switch must be started again. Thus, the relay type automatic power-off energy-saving switch particularly saves electricity, and is combined with a power fuse. The utility model is easy to be installed and convenient to be used.
Description
The utility model belongs to a kind of relay from cutting off the power supply power down switch.
At present, the normal power down switch that uses has of all kinds, patent 89218826.X time-delay battery-conserving switch for example, patent 90202052.8 automatic energy saving relay contactors, patent 90214733.1 power down switchs etc. are under normal operating condition, if circuit has a power failure suddenly, these switches all can not change off-state into from on-state, so, when powering again, tend to cause waste, do not have energy-conservation effect at all.
The utility model partly is made up of machinery and electronics, machinery partly is made up of fuse box, trip bolt, switch cover, backguy, switch enclosure, electronics partly is made up of fuse RD, K switch 1, K2 transition contact chip J-1, relay coil J, uniguide D, capacitor C, K switch 1, K2 link, K2 is the transition reed, and backguy and switch link.
The utility model is when the circuit normal power supply, identical with common pulling switch function, in case circuit is stopped power supply suddenly, this switch can transfer off-state to from on-state at once automatically, when powering again such as need connect this switch again, then must restart, when no circuit non-transformer is supplied, disconnect no matter switch is pulled in where to go up all, so can economize on electricity especially, this switch and main fuse are integrated simultaneously, install easily, and be easy to use.
Description of drawings:
Fig. 1 is the utility model external form schematic diagram;
Fig. 2 is the utility model line map.
The utility model is to increase transition contact chip and fuse plug, socket on the basis of common pulling switch.Mechanical fuse box (1) connects together with switch enclosure (5) partly as shown in Figure 2, and trip bolt (2) can be fastened on switch cover (3) on the switch enclosure (5), and backguy (4) is housed on the switch enclosure (5).Electronics partly as shown in the figure, when power supply is delivered to the A point, arrive K switch 1 again through fuse RD, backguy (4) links to each other with K switch 1, pulling backguy (4) is connected K switch 1, K switch 1 links with K2, K2 is the transition reed, when K1 connects, disconnects voluntarily after the of short duration contact in K2 two ends, when K1 connection and the of short duration connection of K2, power supply through fuse RD and K1, K2 load Rfz again to relay coil J, J get electric after, inhale moving J-1 and connect, still can make load carry the Rfz operate as normal after making K2 disconnect for power supply provides path.In the Rfz course of work, in case the unexpected stop supplies of power supply, J loses electricity and discharges, J-1 is disconnected, owing to K2 disconnects after J work, so after J-1 disconnects, all cut off the path of power supply, global switch is in off state, when circuit is powered again, must restart switch could connect, when in supply line, not having the power supply supply, owing to can not move, so no matter switch is pulled to and where goes up, all be to be in off state, so can economize on electricity especially.
Claims (1)
1, a kind of relay is from cutting off the power supply power down switch, partly form by machinery and electronics, it is characterized in that: machinery partly is made up of fuze box, trip bolt, switch cover, backguy, switch enclosure, electronics is partly by fuse RD, K switch 1, K2, transition contact chip J-1, relay coil J, uniguide D, capacitor C is formed, and K switch 1, K2 link, K2 is the transition reed, and backguy and switch link.
