Thus need to propose a kind of technical scheme, the electric leakage caused comparatively greatly with the space solving the table tail wiring hole of electric energy meter and existence are by the problem of the potential safety hazard of stealing.
Summary of the invention
The object of the invention is to provide a kind of anti-electricity-theft device and electric energy meter, and the electric leakage caused comparatively greatly with the space solving the table tail wiring hole of electric energy meter and existence are by the problem of the potential safety hazard of stealing.
For solving the problems of the technologies described above, according to an aspect of the present invention, provide a kind of anti-electricity-theft device: there is the first insulation division, this first insulation division comprises outer wall and inwall, wherein outer wall side face conically shape, inwall comprises further: extension and closed section, and this extension is formed as circular cylindrical cavity, wherein closed section is formed as conical bores, and the upper end of closed section is connected with the lower end of above-mentioned extension.
Further, said apparatus also comprises the second insulation division, and the cylindrical shape of inwall side face of this second insulation division, upper end is connected with the lower end of the closed section of above-mentioned first insulation division.
According to another aspect of the present invention, provide a kind of electric energy meter, comprise housing, be positioned at the wiring hole on housing and the connection wire through wiring hole, wherein, above-mentioned anti-electricity-theft device is provided with in this electric energy meter, above-mentioned first insulation division puts in above-mentioned housing from above-mentioned wiring hole, and outer wall and the above-mentioned wiring hole of above-mentioned first insulation division are tightly connected.
Further, connect wire and comprise: wire bare wire portion, have the lead body of insulation course, the periphery of fore-end and the circumferential inner wall of above-mentioned closed section in the close wire bare wire portion of above-mentioned lead body are tightly connected.
This programme adopts direct-insert to be arranged on by anti-electricity-theft device on electric energy meter tail wiring hole, thus achieve the full-closed structure of electric energy meter, and, utilize the cross section that the diameter difference of wire and its insulated hull produces, lift this device, thus tail wiring hole can be shown to ammeter and close, the mode making each wiring hole only allow that a wire passes through reaches anti-electricity-theft object.
The present invention has following beneficial effect:
1, utilize simple and easy jacket structure, the electric energy meter tail wiring hole excessive to space is closed, and avoids operating in short-circuit and shunt stealing.
2, week inspection and meter reading personnel can be avoided to get an electric shock, thus effectively ensure that the personal safety of operating personnel.
Except object described above, feature and advantage, the present invention also has other object, feature and advantage.Below with reference to figure, the present invention is further detailed explanation.
Accompanying drawing explanation
The accompanying drawing forming a application's part is used to provide a further understanding of the present invention, and schematic description and description of the present invention, for explaining the present invention, does not form inappropriate limitation of the present invention.In the accompanying drawings:
Fig. 1 is the anti-electricity-theft device of the preferred embodiment of the present invention and the schematic diagram of electric energy meter.
Embodiment
Below in conjunction with accompanying drawing, embodiments of the invention are described in detail, but the multitude of different ways that the present invention can be defined by the claims and cover is implemented.
See Fig. 1, be arranged on wiring hole 32 place of electric energy meter 3 as shown in Figure 1 according to anti-electricity-theft device of the present invention.
As shown in Figure 1, anti-electricity-theft device according to the present invention has the first insulation division 1, this first insulation division 1 comprises outer wall 12 and inwall 14, wherein outer wall 12 side face conically shape, inwall 14 comprises further: extension 142 and closed section 144, this extension 142 is formed as circular cylindrical cavity, and wherein closed section 144 is formed as conical bores, and its upper end is connected with the lower end of above-mentioned extension 142.
According to electric energy meter electric energy meter of the present invention, comprise housing 3, be positioned at the wiring hole 32 on housing 3 and the connection wire 4 through wiring hole 32, wherein, above-mentioned anti-electricity-theft device is provided with in this electric energy meter, above-mentioned first insulation division 1 puts in above-mentioned housing 3 from above-mentioned wiring hole 32, and outer wall 12 and the above-mentioned wiring hole 32 of above-mentioned first insulation division 1 are tightly connected.
Preferably, connect wire 4 and comprise: wire bare wire portion 42, have the lead body 44 of insulation course, the periphery of fore-end and the circumferential inner wall of above-mentioned closed section 144 in the close wire bare wire portion 42 of above-mentioned lead body 44 are tightly connected.
By the outer wall of the first insulation division is made into taper, it is installed does not exist by the pore size of electric energy meter wiring hole size that foozle brings and the problem such as not to mate, and this structure has good sealing effectiveness.In addition, the inwall of the first insulation division has the extension of cylindrical cavity shape, its diameter is more than or equal to wire bare wire portion's wire diameter of connecting wire and is less than the wire diameter of lead body connecting wire, and closed section conically, thus equal to connect the wire diameter place of wire at its diameter and be stuck (lifting effect), therefore also sealing effect is served to the bare wire part connecting wire itself, prevent the situation of leaking electricity from occurring.
