Description

Helical Electric Wire

[technical field]

The utility model relates to a kind of electric wire, particularly relates to a kind of Helical Electric Wire that power supply can be connected on the electric equipment products.

[background technology]

Consult Fig. 1, electric wire 1 comprised in design usually in the past: several leads parallel to each other 11, and one be coated on the outer coating layer 12 of these leads 11, and each bar lead 11 all has the core 111 that a turn-on power is used, and one wraps in the outer plastic insulating layer 112 of core 111.And this coating layer 12 also to be plastic material make, have a smooth exterior surface face 121, above-mentioned outer surface 121 is all identical to the distance of 13 of central axis of electric wire 1.

Electric wire 1 was only considered practical function in design usually in the past; and distinctly coat a layer insulating 112 at the outer surface of each bar core 111; and then utilize coating layer 12 that several strands of leads 11 are combined; this design no doubt can reach the utility function of expection; but use occasion with regard to electric wire 1; it normally is installed on the electric equipment products; relend the electric binding of power supply equipment an of plug and for example socket or the like; therefore; electric wire 1 can protrude in outside the electric equipment products usually, and along with electric equipment products move, that is to say; in the use occasion of general electric wire 1, electric wire 1 is a part of electric equipment products outward appearance.And electric wire 1 was in design in the past, just for example simply utilizing, the coating layer 12 of black is coated on inside with several wires 11, therefore, the visual sense that electric wire 1 shows just is black one, both there be not color change, do not have novel visual sense yet, can destroy the good looking appearance of electric equipment products virtually.

[utility model content]

The purpose of this utility model is to provide a kind of moulding to present helical form, and has the Helical Electric Wire of preferable profile variation and novel visual sense.

A kind of Helical Electric Wire of the present utility model comprises: a lead unit, and a coating unit that is coated on outside this lead unit; It is characterized in that:

This coating unit comprises: at least one spiral first area, and at least one spiral second area, this first area has one first outer surface, this second area has one second outer surface, and above-mentioned first outer surface is different from this second outer surface to the distance between central axis to the distance between the central axis of electric wire.

Helical Electric Wire of the present utility model can make electric wire present helical form, with the profile variation and the novel visual sense of promoting this electric wire.

Below by most preferred embodiment and accompanying drawing the utility model Helical Electric Wire is elaborated, in the accompanying drawing:

Fig. 1 is a kind of stereogram of electric wire in the past;

Fig. 2 is the stereogram of a preferred embodiment of the utility model Helical Electric Wire;

Fig. 3 is a three-dimensional exploded view, and a coating unit of this preferred embodiment is unfolded among the figure; And

Fig. 4 is a front view of this preferred embodiment.

[embodiment]

Consult Fig. 2,3,4, one preferred embodiment of the utility model electric wire is can be attached between a power supply equipment and the electric equipment products, with supply electric equipment products power supply, described power supply equipment is generally: the equipment that household socket, automobile-used socket or the like are common, and this electric wire comprises: a lead unit 2, and a coating unit 3 that is coated on these lead unit 2 outer surfaces.

The lead unit 2 of present embodiment comprises: the lead 21 that triple helix is reeled and linked, these leads 21 are respectively live wire (live wire), zero line (neutral wire) and earth connection (ground wire), each bar lead 21 all has: a core 211, and an insulating barrier 212 that is coated on outside the core 211.

Coating unit 3 of the present utility model is by the plastic material moulding, comprise: an internal layer 31 that coats along the helical surface of lead unit 2, an and skin 32 that is coated on internal layer 31 surfaces, wherein internal layer 31 can be that the plastic material with color is made, be to use the PVC material at present embodiment, outer 32 can adopt printing opacity or semi-transparent plastic material to make, also be to use the PVC material at present embodiment, when internal layer 31 and outer 32 after moulding, this coating unit 3 comprises: the helical form first area 33 of three helical forms and each interval, and three helical forms and 33 the second area 34 between two first areas.Each first area 33 all has one first inner surface 331 and one first outer surface 332, above-mentioned first inner surface 331 has the helical form hump 333 of a central axis 4 projections of a past electric wire, this helical form hump 333 is the intersections that stretch into two strands of leads 21 accordingly, and each second area 34 all has second inner surface 341 that is connected 331 of two first inner surfaces, and second outer surface 342 that is connected 332 of two first outer surfaces, wherein second outer surface 342 arrives the distance 334 of 4 of this central axis less than first outer surface 332 to the distance 343 of 4 of central axis.

When coating unit 3 of the present utility model is coated on the outside of lead unit 2, because coating unit 3 is first and second zones 33 by several each intervals, 34 hand over around forming, and first outer surface 332 of first area 33 arrives the distance 343 of 4 of central axis greater than second outer surface 342 to the distance 334 of 4 of central axis, therefore, in design, electric wire of the present utility model can produce three-dimensional and spiral helicine moulding, if this structure is added the design of internal layer 31 colors and outer 32 printing opacities, more can allow electric wire in practicality, show special profile variation and novel visual sense, so that produce preferable with the electric equipment products collocation of installing, special visual sense of beauty.

In addition, lead unit 2 of the present utility model is except can being three strands of leads 21 of embodiment, also can be that two strands of leads 21 are handed over around forming, it can certainly be four strands, five strands or the like most strands of leads 21 are handed over around forming, in addition, this lead unit 2 also can be a sub-thread, that is to say, the utility model is so long as be provided with at least one spiral first area 33 on coating unit 3, and at least one spiral second area 34, and allow two spiral type zones 33,34 outer surface 332,342 distances 334 to 4 of central axis, 343 differences, just can produce spiral helicine novel visual sense, in design not with lead unit 2 by several strands of leads 21 hand over around and become necessity.
