Compared with prior art, the utility model has the beneficial effects that this kind of arc-fault circuit interrupter, is connected by setting
Device and connecting hole, are interspersed in connector using electric wire, and the end of electric wire is knotted, and form so-called connector lug,
Connector lug will be connected device and block, it is therefore prevented that connector lug is detached from from connector, is inserted into connecting hole using connector screw thread
It is interior, so that connector lug is abutted electric shock piece, facilitates the connection of electric wire and breaker, using the electric action of metal detection head, make neon
Neon in pipe can generate under electric field excitation and transmit the very strong feux rouges of power, be conducive to detect that electric wire connects with breaker is
It is no good.
Detailed description of the invention
Fig. 1 is the utility model structural front view；
Fig. 2 is the cross-sectional view of the utility model connector and connecting hole junction.
In figure: 1 breaker body, 11 knife switches, 12 connecting holes, 13 electric shock pieces, 2 connectors, 21 metal detection heads, 22
Resistance, 23 neon tubes, 24 enlarging lens, 25 springs, 26 metal ends, 3 electric wires, 31 connector lugs.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
The utility model provides a kind of technical solution referring to FIG. 1-2: a kind of arc-fault circuit interrupter, including breaker
Ontology 1, knife switch 11 is equipped in the middle part of the breaker body 1, and described 1 upper end of breaker body or so two and lower end are left
Right two are provided with connecting hole 12, and electric shock piece 13,12 inner cavity of connecting hole are fixedly installed in the middle part of 12 inner end of connecting hole
Middle screw thread is plugged with connector 2, and 12 inner wall of connecting hole is provided with internal screw thread, and 2 outer wall of connector is provided with external screw thread, and outer
Screw thread is plugged in internal screw thread, and the connector 2 is ambroin connector, and metal spy is equipped in the connector 2
Gauge head 21, resistance 22, neon tube 23, enlarging lens 24, spring 25 and metal end 26,21 outer end of metal detection head is fixed to be connected
It is connected to resistance 22,22 outer end of resistance is fixedly connected with neon tube 23, and 23 outer end of neon tube is fixedly connected with spring 25, described
25 outer end of spring is fixedly connected with metal end 26, and the 2 outer end side wall of connector is equipped with enlarging lens 24, the connector
Run through grafting live wire 3 in 2,3 inner end of electric wire is equipped with connector lug 31,31 snap connectors 2 of connector lug, by will be electric
Line 3, which runs through, to be inserted into connector 2, and the end of electric wire 3 is knotted, and forms connector lug 31, meanwhile, connector lug 31 will
