Abstract
The invention relates to an elastic wire plug applied to an electric tool. The elastic wire plug applied to the electric tool comprises a plug body and a wire; two ends of the plug are respectively used as an inserting end and a connecting end; two inserting channels are arranged in parallel in the inserting end; the connecting end is connected with the wire; the wire comprises two wire cores and an insulating sheath which wraps the outsides of the wire cores; a PVC insulating layer wraps the outsides of the wire cores; the two wire cores are fixed in parallel into the insulating sheath; a wire body is arranged as a spiral structure, and two ends of the wire are respectively fixed through a first wire clamp and a second wire clamp; the wire body of the spiral structure is arranged in 79+/- 3 loops in total, and the wire body is 645+/-25mm in length; the first wire clamp is of a cylindrical structure, 25mm in outside diameter, and 65.5mm in length; the second wire clamp is 10.2mm in outside diameter. According to the elastic wire plug, the telescoping function is improved, and meanwhile, the service life is prolonged.
Description
Technical field
The present invention relates to a kind of plug, particularly relate to a kind of elastic thread plug for electric tool.
Background technology
At present, the electric power connection line be conventionally used on electric tool (as grass-mowing machine, hay mover etc.) is that thermoplastic macromolecule material is made, and non-telescopely says.Run into need regulating handle to extend to beat the grass or mow radius time; current solution is the electric wire of reserved certain length on the take-up reel of electric tool (grass-mowing machine, hay mover etc.) in advance; so that the use of elongation; and long-term straight shape is stretched; greatly reduce the useful life of mains cord; often can cause because frequency of usage is too high, cause the fracture of inner conductor (copper wire), and accidents caused.
Summary of the invention
The object of this invention is to provide a kind of elastic thread plug for electric tool, strengthen Telescopic, increase the service life simultaneously.
For solving the problems of the technologies described above, technical scheme of the present invention is:
A kind of elastic thread plug for electric tool, comprise plug and electric wire, wherein, the two ends of described plug are respectively insertion end and link, parallelly in described insertion end be provided with two grafting passages, described link is connected with electric wire, described electric wire comprises two cores and is coated on the insulating sleeve outside core, described core outer cladding one deck PVC insulating barrier, what two cores were parallel to each other is fixed in insulating sleeve, the main body helically vibrational power flow of described electric wire, the two ends of electric wire are fixed respectively by the first line card and the second line card, the electric wire main body of described helically structure arranges 79 ± 3 circles altogether, principal length is 645 ± 25mm, described first line card is cylindrical structural, the external diameter of the first line card is 25mm, length is 65.5mm, the external diameter of described second line card is 10.2mm.
Above-mentioned a kind of elastic thread plug for electric tool, wherein, the body outer diameter≤22mm of the electric wire of described helically structure.
Beneficial effect of the present invention is:
The present invention is by carrying out around rod, baking molding to the thermal plastic high polymer cable of change material, make the magnification of the main body of shaping spiral wires at more than 1:9, the product of equal length is made to have great extendable room, make the use of electric tool more handy, act freely, decrease because the straight shape of traditional flexible cord shrinks the conductor copper wire fracture caused, spirality shrinks the useful life by greatly strengthening machinery simultaneously.
Connector of the present invention should through 1250V high pressure 1min without punch-through, the pulling-out force > 160N of the first line card and the second line card.

Fig. 2 is electric wire A-A cutaway view of the present invention.
Fig. 3 is the present invention first line card B-B cutaway view.
Fig. 4 is plug side view of the present invention.
Embodiment
Below by way of specific embodiment, the specific embodiment of the present invention is described in further detail.
As shown in the figure, a kind of elastic thread plug for electric tool, comprise plug 1 and electric wire 2, wherein, the two ends of described plug 1 are respectively insertion end 3 and link 4, parallelly in described insertion end 3 be provided with two grafting passages 5, described link 4 is connected with electric wire 2, the insulating sleeve 6 that described electric wire 2 comprises two cores 5 and is coated on outside core, described core 5 outer cladding one deck PVC insulating barrier 7, what two cores 5 were parallel to each other is fixed in insulating sleeve 6, the main body 21 helically vibrational power flow of described electric wire, the two ends 22 of electric wire, 23 are fixed respectively by the first line card 8 and the second line card 9, the electric wire main body 21 of described helically structure arranges 79 ± 3 circles altogether, principal length L1 is 645 ± 25mm, body outer diameter D1≤22mm, described first line card 8 is cylindrical structural, the outer diameter D 2 of the first line card 8 is 25mm, length L2 is 65.5mm, the outer diameter D 3 of described second line card 9 is 10.2mm.
The present invention is by carrying out around rod, baking molding to the thermal plastic high polymer cable of change material, make the magnification of the main body of shaping spiral wires at more than 1:9, the product of equal length is made to have great extendable room, make the use of electric tool more handy, act freely, decrease because the straight shape of traditional flexible cord shrinks the conductor copper wire fracture caused, spirality shrinks the useful life by greatly strengthening machinery simultaneously.
Connector of the present invention should through 1250V high pressure 1min without punch-through, the pulling-out force > 160N of the first line card and the second line card.
Here description of the invention and application is illustrative, not wants by scope restriction of the present invention in the above-described embodiments, and therefore, the present invention is not by the restriction of the present embodiment, and the technical scheme that any employing equivalence replacement obtains is all in the scope of protection of the invention.
