Description
Technical field
Movable electric tool power transmission cable is the utility model is related to, belongs to the security power transmission electricity of electric tool
Cable technical field.
Background technology
The existing cable used as movable electric tool power cord, its internal conducting wire, which generally uses, to be arranged side by side.
In actual use, there are some potential safety problems for this construction of cable.Such as transmission cable high-pressure conductor it is exposed when, lead to
Cross human body grounding forming circuit, caused by electric shock；Or two bare spots and human body not on same conducting wire of transmission cable
Forming circuit, caused by electric shock；Under this situation, if there is high current to flow through heart or brain, major accident can be caused, or even extremely
Die.
The content of the invention
The utility model aim is to solve asking for the safety of structure of existing movable electric tool power cable difference
A kind of topic, there is provided movable electric tool power transmission cable.
Movable electric tool power transmission cable described in the utility model, it includes center conductor, inner insulating layer and outer
Layer conductor,
Center conductor is identical with the Transverse sectional areas of outer layer conductor；
Center conductor outer surface sets inner insulating layer, and outer layer conductor is arranged on the outer surface of inner insulating layer.
The advantages of the utility model：The movable electric tool power transmission cable of the disclosure is set side by side by existing conducting wire
The structure design changed as coaxial manner is put, it can use outer layer conductor as current supply line, another conductor quilt
The center of cable is wrapped in, has prevented human body from structure and has touched two kinds of conducting wires at the same time, produced circuit and cause to get an electric shock
Possibility.
The power cable of the mobile instrument of the disclosure can coordinate isolated power supply to use, its construction of cable and isolated power supply energy
Enough form a power utilization environment without security risk, there is provided safe line no-voltage electrical power transmission system over the ground.In addition, pass through this
Open cable provides the electric tool of electric power when in use, and there is no the electric shock crisis of in the following manner：That is the electric shock danger of people over the ground
Machine；When electric shock crisis and zero curve of certain root conducting wire to people or to another conducting wire loosen, the electric shock crisis of whole system.
Brief description of the drawings
Fig. 1 is the structure diagram of movable electric tool power transmission cable described in the utility model；
Fig. 2 is the power transmission cable structure diagram for having external insulation layer；
Fig. 3 is the specific implementation schematic diagram of power transmission cable described in the utility model.
Embodiment
Embodiment one：Illustrate present embodiment, portable electricity described in present embodiment with reference to Fig. 1 to Fig. 3
Power driven tools power transmission cable, it includes center conductor 1, inner insulating layer 2 and outer layer conductor 3,
Center conductor 1 is identical with the Transverse sectional areas of outer layer conductor 3；
1 outer surface of center conductor sets inner insulating layer 2, and outer layer conductor 3 is arranged on the outer surface of inner insulating layer 2.
Shown in Fig. 1, center conductor 1, inner insulating layer 2 and outer layer conductor 3 can sequentially coaxially be set, when selection center conductor
1 is power transmission line, and outer layer conductor 3 is used as another transmission line, is not provided with insulating layer in outer 3 outer surface of layer conductor, in use
And safety.Because after the people on ground contacts outer layer conductor 3, potential difference will not be formed in human body, therefore electricity will not be formed
Stream.Center conductor 1 is identical with the Transverse sectional areas of outer layer conductor 3, can ensure to meet that the power transmission of power supply uses.Center conductor
1 and outer layer conductor 3 Transverse sectional areas can at most have 5% deviation.
Outer layer conductor 3 can be uniformly dispersed in the outer surface of inner insulating layer 2, form being completely covered to center conductor 1,
So as to which further center of serve conducting wire 1 will not be exposed, human body can not be touched center conductor 1 through outer layer conductor 3, avoid making
Into accidental shock.
As the preferred embodiment of the disclosure, external insulation layer 4 can also be further set, as shown in Fig. 2, using external insulation layer
4 are wrapped in the outer surface of outer layer conductor 3, so that the electrical transmission conducting wire of cable is all isolated by insulating layer with external environment condition.
Both the safety used was further ensured, can also facilitate transport in use.
It is circular center conductor 1 for cross section, outer layer conductor 3 is in its outer shroud, it can be provided same with center conductor 1
The cylindrical shape of axis.
Further, inner insulating layer 2 and external insulation layer 4 also can be cylindrical shape, and be coaxially disposed.
As the presently preferred embodiments, center conductor 1, inner insulating layer 2, outer layer conductor 3 and external insulation layer 4 can be socketed successively,
Form coaxial cable.
A kind of schematic diagram of specific implementation is provided in Fig. 3, center conductor 1 can use the conducting wire with more cluster subbranches to be total to
With being formed, outer layer conductor 3 can also be realized jointly using the conducting wire of more cluster subbranches, and small point of more clusters of outer layer conductor 3
Branch is uniformly dispersed on the outer surface of inner insulating layer 2.
The disclosure is used in the transmission of portable electrical source of power, will by the center conductor 1 and outer layer conductor 3 of coaxial cable
Electrical energy transportation is to power equipment.
Isolated power supply is coordinated to use the disclosure, since outer layer conductor 3 can not independently form circuit, its voltage-to-ground is
Zero, it is possible to effectively avoid the generation endangered of getting an electric shock.
