Description
Technical field
The utility model relates to conducting wire connection areas, particularly relate to a kind of Wire tap-off unit.
Background technique
Currently, artificial winding, coupling box (box), conductor shunt, puncture insulating clamp etc. is mostly used to carry out insulated conductor
Connection or branch, but the above method exist cannot quickly, standardization connection, branch the shortcomings that.Artificial winding method, this method are more
Connection or branch for conductor cross-section no more than 10 squares, are not suitable for large-section lead, while the technique is cumbersome, connection
A large amount of artificial and times will be expended；Since manual operation is multifarious, so quality cannot be guaranteed, have become backward and naughty
The construction method eliminated.Coupling box method, this method needs to occupy biggish space (cabinet is larger), and cabinet needs certain structure
Support or load-bearing, are not available in overhead transmission line or buried route；In addition, cabinet standard does not have Uniform provisions, given birth to by distribution box
Producer's voluntarily control is produced, so quality is irregular；It is connected by screw bolts between copper bar and conducting wire, connection depends entirely on scene
There are the electrical hidden danger such as sparking, electric leakage or electrical hazard in construction worker, junction, so the way is also gradually being washed in a pan in recent years
It eliminates.Conductor shunt runs through bolt between upper and lower two metallic conductors, screws reality by bolt using metal conduction principle
The purpose of metallic conductor and electrified wire compression above and below now.It may be implemented connection or the branch of conducting wire, but the product or invention
There is following fatal drawback to cannot achieve the standardization of connection, i.e., connection or bifurcation stress are random, by construction environment and are applied
Work worker changes and changes.To cause connection or bifurcation to loosen, sparking, the accidents such as burn or conducting wire are generated from setting
Standby skid off causes to have a power failure, or even causes fire and shock hazard；Connection or bifurcation wire insulation need in-situ processing, or by factory
Family provides plastic protection box and does simple protection, and the protective performance of connection or bifurcation substantially reduces (including the class of insulation, protection etc.
Grade, instrument strength etc.), conducting wire service life is reduced, electrical safety hidden danger is also buried；The product operational procedure is cumbersome, increases
It is affixed by work cost of labor；The product is suitable only for aerial condutor, and indoor conducting wire and buried conductor are not suitable for.Insulating clamp is punctured, it should
Product does not destroy wire insulation, and the standardization of connection may be implemented, while greatly reducing the set-up time, reduces engineering and makes
Valence.But since conducting wire technique producer, China is multifarious, the connection effect of cutter tooth and conducting wire is affected, in addition existing cable
35 squares of producer or more conducting wire is not concentric circles, and part cutter tooth could not be reliably connected after puncturing insulation with cable conductor, so going out
Now a large amount of connection position heating or occur electrical fire accident, especially domestic wire clamp, performance is unstable, caused by safety it is hidden
Suffer from especially severe, so engineering starts to repel penetrating cable clamp now.Wire connection assemblies, the product connect suitable for small section lead
It connects, is similar to docking tubing product, be not suitable for electric cable with large cross-section (electric cable with large cross-section conducting wire is not round)；It cannot be used for conducting wire
Branch.
In conclusion the said goods in addition to import penetrating cable clamp, all cannot achieve product connection or the standardization of branch；All
The reliability of connection or branch is not can fully ensure that；And above-mentioned all products, connection or branch can not be realized on mineral cable.
Therefore design that a kind of standardization, the Wire tap-off unit that construction is simple is quick, highly reliable is necessary.
Utility model content
To solve the above problems, realizing the standard of conducting wire connection or branch the utility model proposes a kind of Wire tap-off unit
Change, and construction is simple is quick, it is highly reliable.
The technical solution of the utility model is achieved in that device includes electric conductor, insulation shell, wire guide, torque spiral shell
Bolt and Wire sheath；
Fixation is covered with insulation shell on the outer wall of the electric conductor, and more than one wire guide is provided on side wall；
It is provided with threaded hole on the side wall of the wire guide, is engaged with torque bolt, for compressing the conducting wire in wire guide；
The Wire sheath is fixedly mounted at wire guide.
Further, it is provided with the texture of concaveconvex shape on the side wall of the wire guide, increases contact area, ensure that and lead
The reliability that line is connect with electric conductor.
Further, the Wire sheath is spring-backed quill, to be applicable in the conducting wire of different line footpaths, guarantees that conducting wire is inserted into conducting wire
Airtightness behind hole.
Further, the insulation shell is moulding, and insulation shell has the characteristics such as pressure resistance, fire resisting, corrosion-resistant, anti-aging,
Insulation shell is fixed as one with electric conductor, realizes pre insulated.By integrated structure, the mechanically performance of junction is improved
And insulation and degree of protection.
Further, the quantity of the torque bolt is determined by sectional area of wire, when sectional area of wire is flat less than or equal to 95
When square millimeter, the quantity of torque bolt is one, and when sectional area of wire is greater than 95 square millimeters, the quantity of torque bolt is two
It is a.
Further, the quantity of the wire guide is no less than required wire branch number.The outside of wire guide can identify and lead
Line strip length is convenient for guiding construction.
The utility model is generated the utility model has the advantages that by torque bolt compared with background technique, makes conducting wire and electric conductor
Sufficiently connection, does not change because of the difference of construction, realizes the standardization of connection, ensure that the reliability of connection；Overall structure
Pre insulated processing is done, scene need not do protective treatments, the construction is simples such as any insulation again and shorten construction period, can be quick
It realizes conducting wire connection or branch, reduces costs；Insulation shell is that moulding is fixed as one with electric conductor, improves junction
Mechanical performance and insulation, degree of protection.
