Description
Technical field
The present invention relates to a kind of feeder line that is used to transmit high-frequency current.
Background technology
Japan's special permission discloses flat 5-190026 communique and discloses the feeder line that a kind of a plurality of ring shaped conductor sandwich insulating barrier forms with the concentric circles configuration.Generally, in transmitting the feeder line of high-frequency current,, therefore exist alternating current only to flow near conductive surface tendency if the frequency gets higher of electric current then can produce kelvin effect, its result, the resistance of lead increases, thus loss enlarges markedly.The skin depth d of ordinary representation kelvin effect degree can represent by following formula:
Skin depth: d=(2/ ω σ μ)
1/2
ω: frequency; σ: the conductance of material; μ: the magnetic permeability of material.
That is, if the thickness of feeder line is to depend on so just can reduce the current loss that kelvin effect causes below the skin depth d of frequency.Therefore, in described existing feeder line, be made as 1 micron by thickness and suppress current loss each ring shaped conductor.
But there is following problem in the feeder line of this structure: owing to need the operation of repeated multiple times coated insulation layer on the surface of ring shaped conductor, so manufacturing time is elongated, in addition, the location of ring shaped conductor is difficult to.
Summary of the invention
The present invention makes in view of described problem, and its purpose is, a kind of high-frequency current loss that not only can reduce is provided, and can also improve the high frequency current feeding conductor of making efficient.
Feeder line of the present invention is made of the insulating sleeve of conductor and this conductor of coating.Conductor forms the single structure body, and on the cross section perpendicular to the conductor length direction, the part of conductor and other parts are separated predetermined distance at least one direction in this cross section of crosscut.Insulating sleeve is the formed body of synthetic resin, and described conductor is integrally formed in the described insulating sleeve.Thus, conductor is cut apart on the direction vertical with the flow direction that electric current produced that flows through conductor, so can reduce the loss of the electric current that causes by kelvin effect, and, can improve manufacturing efficient by in the insulating sleeve of resin molded body, the conductor of single structure body being formed as one.
Preferably, conductor forms on described cross section and closes the space, and the part of conductor and other parts are closed spaced apart by this.In the case, close the space and be not insulated resin and be full of, so this closes the space and can use as the space that can insert connecting elements of feeder line.
In addition, preferably, described conductor has inner core and urceolus, and described inner core and described urceolus only a position on mutual girth combine.Constitute conductor by inner core and urceolus like this, can either make each attenuation, can improve the conductor integral intensity again.In addition, on the almost full girth of conductor, inner core and urceolus are separated along radial direction, therefore on the direction vertical with the direction of the magnetic flux that electric current produced that flows through conductor, can make the thickness attenuation of conductor, and then can make the loss of electric current become minimum.
Further, preferably, described urceolus is made of curved portions and par, and this curved portions and this par are on described cross section, and its profile is outstanding laterally.Described par can be used as the contact-making surface with connecting elements, and wherein this connecting elements is used to connect feeder line, thereby can realize stable being electrically connected with connecting elements.
In addition, preferably, described urceolus is made of a pair of par and a pair of curved portions, and on described cross section, the left and right sides is opposed mutually on diametric(al) in this a pair of par, and this a pair of curved portions is outstanding up and down laterally.In the case, the reliable connection between the feeder line can by the connecting elements that use has the shape of 2 pars of clamping, can be realized as feeder line and contact-making surface connecting elements in 2 pars.
Preferably, described conductor dbus is crossed crooked metallic plate and is formed.Thereby so can make the thickness attenuation of conductor each several part suppress current loss, and can easily produce the cross sectional shape of regulation.
Further, preferably, the cross sectional shape of described conductor on its full girth, is cut apart with the interval of regulation along radial direction.In the case, the part that can arrange the conductor of a plurality of minimal thickness simultaneously on the radial direction makes the sectional area that has not only reduced current loss but also increased conductor, thereby can guarantee bigger current capacity.
