Abstract
The utility model relates to a safety socket which can be automatically cut off while in power interruption, which is composed of a standard panel, a jack, a neon lamp, a current-limiting fuse, etc. The utility model is characterized in that a relay and an elastic button are arranged. After a socket is in power failure, the power supply can not be automatically recovered. The power supply can be recovered by manual operation only; the elastic button is operated, and the closed state of the contact is maintained by the electromagnetic force of the relay after the two contacts of the relay are closed. The utility model is a novel socket with simple structure and reliability.
Description
The utility model belongs to the power connector field, refers in particular to a kind of back that has a power failure from the safety socket that opens circuit.
Along with the application of various consuming devices, the style of socket and function also constantly increase, as energising demonstration, belt switch, voltage indication, current limliting fusing insurance etc.These function combinations greatly facilitate use on socket.But it is that these sockets all do not possess that a defencive function is arranged, and promptly is when restoring electricity after outside line has a power failure again, and the automatic outage of socket does not restore electricity with the protection electrical appliance.
The purpose of the utility model is to propose a kind of outside line power failure rear socket automatic disconnection of working as, and needs the artificial socket device that recovers just can make socket connector charged when circuit restores electricity.
The purpose of the utility model realizes by following scheme: the power failure self-stopping type safety socket of being made up of standard panel, jack, neon lamp, current limiting fuse etc., establish a relay at input, establish an elasticity knob before the moving contact of relay, when press knob with the relay contact adhesive after, the electromagnetic force of relay can keep this state, after the power down, moving contact promptly automatically springs open the purpose that reaches cutoff circuit.
Accompanying drawing and drawing explanation:
Figure one is a front view of the present utility model;
Figure two is left cutaway views of the present utility model;
Figure three is tie lines schematic diagrames of the present utility model.
1---two jacks; 2---three jacks; 3---neon lamp; 4---the elasticity knob; 5---current limiting fuse; 6---relay.
Below in conjunction with accompanying drawing and drawing explanation the utility model is described in further detail: on the standard panel, be provided with two jacks 1, three jacks 2, indication neon lamp 3, current limiting fuse 5, in the utility model, be provided with a relay 6, before the moving contact of relay 6, an elasticity knob 4 arranged, when relay is charged, need manually by the dynamic elasticity knob with the relay contact adhesive after, the electromagnetic force of relay can keep this state, make the reed of jack charged.After the circuit power down, moving contact promptly automatically springs open, the reed outage, and when circuit restored electricity, because relay is not charged, two contacts can't be closed, plays the effect of protective circuit.
In sum, because the utility model only is to have increased a relay and manual knob, makes and must artificially manually could recover socket and power, is one simple in structure, reliable new type of safe socket.
Claims (1)
- Power failure self-stopping type safety socket, form by standard panel jack, neon lamp, current limiting fuse etc., it is characterized in that: establish a relay at the input of socket, establish an elasticity knob before the moving contact of relay, when press knob with the relay contact adhesive after, the electromagnetic force of relay can keep this state, and after the power down, moving contact promptly automatically springs open the purpose that reaches cutoff circuit.
