Specific embodiment
Technology contents, construction feature, the objects and the effects for detailed description technical solution, below in conjunction with specific reality
It applies example and attached drawing is cooperated to be explained in detail.
The present embodiment provides a kind of referring to FIG. 1 to FIG. 4, and the Intelligent electric leakage with function of short circuit detection monitors miniature open circuit
Device, including current release 10, bat-handle switch 20, double gold tripping feeler levers 30, touch-switch 40 and shell 50, shell is provided with de-
Detain cavity 51.From top to bottom successively according to double gold tripping feeler levers, current release and touch-switch in tripping cavity.Positioned at de-
It detains and opens up a switch notch on the side wall of cavity, so that the handle of bat-handle switch passes through the switch notch and is placed in the outer of shell
Portion, and the midline position of the change of bat-handle switch passes through bolted splice in tripping cavity, and people are opened by handle
The handle of pass drives its change to rotate, and achievees the purpose that drive double gold tripping feeler levers and current release closure or openness.
A tripping cavity is opened up in the present embodiment in shell, when bat-handle switch is in the state closed, double gold are de-
The top contact separation of feeler lever and current release is detained, and the bottom end contact of current release is then connect with touch-switch.Work as hand
When handle switch is closed, the top contact of double gold tripping feeler levers and current release is mutually close.When short circuit occurs for circuit, electric current is de-
Button device can have trip operation, so that current release is separated with touch-switch, generally, have activity among current release
