FLEXIBLE HIGH VOLTAGE LINE Filed Oct. 29, 1937 1!! Hi :lg H; :i: 4 l'l l I I l l 7 INVENT RS Ell/L Z/TT /C/'/ BY KARL wyL ATTORNEY Patented Nov. 26, 1940 UNITED STATES A PATENT OFFICE.
FLEXIBLE HIGH VOLTAGE LINE Application October 29, 1937, Serial No. 171,726 In Germany November 5, 1936 'iClaims.
This invention relates to a flexible and corona. free line for very high voltages which may be used, for instances, in movable apparatus to which the highest voltages are to be applied, more especially for. high-frequency.
A feature of the invention is a flexible high voltage line having metal balls placed in a row over a litz wire with bores of the balls that are widened out.
The use of ordinary flexible litz wires, or the like, for conducting very high voltages (for instance, 50 kv), is practically impossible especially in case of higher frequencies, since the 15 lines reveal an extremely high corona effect in view of the fact that the amperage that can be conducted is limited in case of a diameter that is most favorable with respect to flexibility. In accordance with the novelty, a line is used for conducting very high voltages which is characterso ized in that metal balls are placed in a row on a flexible litz wire, whereby the bores of said metal balls are widened out on one side, respectively;
while the balls are pressed against each other 85 by a spring force.
An example of construction according to the novel feature is shown in the drawing.
Character i designates the flexible litz wire consisting of conducting or non-conducting materialand preferably of a wire rope to provide sufi'icient mechanical strength. This litz wire carries a row of metal balls (shown as hollow balls in the flgure) 2, l, 4 etc. As can be readily seen from the flgure, always one of the two bores 35 is widened out. Thus, the ball 3, for instance, has an upper bore whose diameter is just sufficient for pulling through the litz wire, while the lower bore is widened out to more than twice the size, so that the bore rests on the upper side of the 0 metal ball I, thus making contact with the latter on a surface of considerable size. The end of the litz wire i has a helical spring 5 fastened thereto, pressing all balls against each other, so that no open gaps can appear between the in- 45 dividual balls when bending the line, and the balls rest upon each other always with the same size of the contact surface. The lower end ball has an extension I provided with a connection screw or connection terminal I with which the line 50 can be connected. The upper end of the line may be constructed identically with the lower end, and likewise provided with a helical spring. The line is equally well suited for conducting low frequencies or high frequencies. In case of 55 high frequencies it will be of advantage to choose the bores as wide as possible in order that the current which always flows over the outside of the balls has at each place a large conducting surface available.
As furthermore seen from the figure, the wid- 5 ened bores are chamfered such that they fit accurately on the surface of the following ball so that always a uniform electric contact is assured.
Owing to the large conducting surfaces at all places of the line and due to the enlarged bores at the places of contact between the balls, considerable amperages can be conducted across the line.
