Reconnection brings hidden danger；Third, operator arbitrarily throws away after often removing used insulating tape, not only cause to waste, but also
Influence workshop health.
Invention content
The shortcomings that the purpose of the utility model is to overcome the prior arts provides a kind of insulation of metering secondary conducting wire
Wire protection clamp solves, at present using the practice of insulating tape package nuditing wire, the person easily to occur and gets an electric shock and equipment short circuit accident, together
When the technical issues of bringing hidden danger to reconnection.
The utility model is achieved through the following technical solutions：
A kind of insulation wire protection clamp of metering secondary conducting wire, it is characterised in that：The metering secondary conducting wire it is exhausted
Edge wire protection clamp includes：Twayblade, spring, the blade of the twayblade and the middle part of lower blade by together with stud connection,
The first half that upper leaf piece and lower blade are located at hinged shaft is clamping opening, and the latter half for being located at hinged shaft is pressed handle, the bullet
Spring is nested in the slot for cutting with scissors axial upper leaf piece and lower blade；Clamping opening after upper leaf piece and lower blade fastening
Shape, will be inside and outside it with black colored insulating material in conical outer form, the clamp mouth part of round cavity in coniform, inner cavity is rounded
Covering is formed batswing tab and is wrapped up using insulation sheath at upper and lower two pressed handles.
Further, the pressed handle is wrapped up according to the difference that voltage, electric current are separate using the insulation sheath of different colours.
Further, the polar end of voltage, electric current is indicated on the crust of the clamping opening with symbol " * ".
Further, the round cavity diameter and length of the clamping opening, most according to live meter voltage, the exposed the end of a thread of electric current
Big section and Design of length.
Further, the round cavity of the clamping opening is serrated.
The utility model carries out meter compared with prior art, due to the use of " metering secondary wire insulation wire protection clamp "
Rotation or secondary circuit Inspection, significantly reduce the activity duration, have saved working hour；Insulation wire protection clamp, which can be repeated several times, to be made
With having the function that energy saving, environmentally protective；It is distinguished according to the separate and polarity of voltage, electric current, is convenient for wiring check
With recovery, the accuracy of metering secondary wiring is improved；It is most important be a cancellation in operation the person get an electric shock it is short with equipment
The security risk on road has ensured the metrological personnel field operation person and equipment safety.
The utility model is used for electric energy meter rotation and metering secondary inspection, has conveniently intuitively, conducive to restoring to connect
Line prevents the advantages of person gets an electric shock with equipment short circuit accident.

Specific implementation mode
In conjunction with attached drawing, the technical solution of the utility model clearly will completely be described below.
As shown in Figure 1, 2, a kind of insulation wire protection clamp of metering secondary conducting wire, including：Twayblade 1, spring 2, it is described
The middle part of the blade 1.1 of twayblade 1 and lower blade 1.2 is linked together by hinged shaft 3, upper leaf piece 1.1 and lower blade
1.2 first halfs for being located at hinged shaft 3 are clamping opening A, and the latter half for being located at hinged shaft 3 is pressed handle B, and the spring 2 is nested in place
Upper leaf piece 1.1 around hinged shaft 3 and in the circular groove of lower blade 1.2 (spring is normal pressure state)；1.1 He of upper leaf piece
Lower blade 1.2 fasten after clamping opening shape in coniform, inner cavity is rounded, conical outer form, round cavity clamping opening A at,
With black colored insulating material by its inside and outside covering, batswing tab 4 is formed, at upper and lower two pressed handle B, is wrapped up using insulation sheath 5.
During use, upper and lower two pressed handles are pinched with hand, the elastic force of spring is overcome, clamping opening is made to open, eat and lead
Line exposed part makes conducting wire exposed part integrally be wrapped in insulating covering, securely and reliably, is not easy de- folder.
In order to distinguish voltage, electric current it is separate, the pressed handle B using different colours insulation sheath 5 wrap up, such as yellow
Indicate that A phases, green indicate that B phases, red indicate C phases.
In order to distinguish the polarity of electric current, symbol " * " is used to indicate polar end on the crust of the clamping opening A.
The round cavity diameter and length of the clamping opening A, according to the maximum cross-section of live meter voltage, the exposed the end of a thread of electric current
With Design of length.
The round cavity of the clamping opening A is serrated, and prevents clamp from falling off.
The utility model has the advantage that compared with prior art：
1, when new clothes electric energy meter (power failure), it is secondary that voltage, electric current are distinguished using the insulation wire protection clamp of different colours
Every line of return wire, it is convenient intuitive, it is conducive to secondary circuit cable alignment and wiring check.
2, when rotation electric energy meter (electriferous state), different colours insulation wire protection clamp, correct area are used according to former correct wiring
Component voltage, the separate and polarity of electric current secondary connection are conducive to reconnection, and can play insulated separation, it is therefore prevented that are made because accidentally touching
At the person get an electric shock with equipment short circuit accident.
