Application filed April 15, 1925. Serial No.-23,297.
This invention relates to inductors of the type used with, high-frequency currents. More particularly, it relates to the means of securing such inductors in place. A
It is an object of this invention to provide' a support and fastening means for a coil of the basket-weave type which can'be rapidly and easily assembled andwhich is constructed of inexpensive parts. p
It is a further object of this invention to provide a mounting for a coil of this type which shall hold the coil firmly in place and shall accurately position the coil in the ,ap:
paratus of which it forms a part.
Other objects of the invention and details.
be of the type known as a basket-weave coil.
Such coils are wound upon a form consisting of a number of parallel plus or rods.
The winding is made bypassing thewire outside of one pin, inside of several pins, outside of the next pin, then inside'of the same number of pins as before, and. repeat-. mg.
The number of pins concerned in a single step of this winding is not a divisor. of the total number of pins. Consequently, the second turn of the winding-passes outside of different pins from the first turn. The successive turns are, therefore, staggered with relation. to one another and the wire, where it passes one side of any given pin, is spaced from the wire of other turns on the same side of the same pin. i
A consequence of this method of winding is that the wire forms a series of cells, par-' allel with the axis of the coil, a cell around each pin. When the coil is removed from the pins, these cells constitute openings, each extending through the coil from one end face to the other. 7
Strips of insulating material 4 are provided, each having a shank 5 and a head 6. Each strip has a shoulder 7 at the junction of the shank 5 and the head 6. The width of the shank 5 is suliicient to occupy a cell from wall to wall. The width of the head 6 is such that the shoulder 7 extends beyond 8aMANUFACTURING COMPANY, ACORPORATION or rENN- the wall ofthe cell, enabling the shoulder to abut. against the end surface of the coil.
The strlps 4 are inserted'into the coil, as
best shown inFig. 1. The left hand strip .8 in this figureis introduced from the upper 'endof the coil. Consequently, the shoulder of its head 6 comes against the upper,
end ofthe coil and its shank 5 extends beyond the lower end of the coil.
Its head,l0,therefore, provides a shoulder 11 contacting the lower edge of the coil. The shank 12 ofthisstrip. extends above the upper edgeot the coil. 1
The strip 9 is fart-her from the axis of the coil than the strip 8. The two strips have suflicient thickness to occupy allthe distance,
I Astrip 9 i of the same size and shape is inserted into the same, cell from the lower end of the coil.
radially of the coil, which the cell 'afiords for strips of the width of the shank 5. The edges of the shank 5 of the strip 9 are therebybrought into close contact with the outer,v
walls of the cell,and the face of the inner strip 8. contacts with thenearlyv flat inner wall of the cell. ,7 y
At the right-hand side of Fig. 1 a similar pair of strips are shown inserted in the op- 1 =v ,pos te order, whereby thehead 13 of the innerstrip is adjacentt o the lower edgeof the coil and'the head 14 of the outer strip is adjacent to the upper edge of the coil.
When the strips are. thus inserted, the width of the shanks prevent-s relative motionbetween any. strip and the coil, except,
lengthwise of the strip. The two heads, one on. each strip, prevent motion; of the'coil lengthwise of the strips, because the strips cannot moverelative to each other. for reasons explained below.. In addition, the
strips and the coil may, if:desired,'be held together by varnish 'or any other suitable binding material.
At the end of the head 6 opposite the shank 4:, each strip has a tongue-15 by means of which the whole structure including the coil and strips may be mounted in any suitable brackets.
Two brackets 16 and 17, best shown in Fig. 4:, are provided. These are mounted upon any suitable support 18, preferably-0t to the base 18 and the coil is put into posi tion with the tongues 15 at one end and the ends of the shanks at the same end extending through the openings 19 of said bracket.
The other bracket is then placed with the openings 19 j embracing the remaining tongues 15 and the ends of the other shanks.
The latter bracket is then secured to the,
The coil and mounting constitute a unitary structure, the assembly of which is easy, calls for no skilled labor and may be rapidly performed. The mounting is light and rigid and introduces a minimum of losses.
Although the specific description and illustration has been made with reference to a coilwound outside one pin and inside several pins, obviously the same method of mounting may be applied to windings which pass outside of several pins and inside of others. VVindings made in this way do not produce a coil of the ribbed appearance which the coil illustrated possesses, but they have cellularprismatic openings extendin lengthwise therethrough which may be use" for the method'of mounting disclosed herein.
Other modifications of the structure will readily occurto those skilled in the art and it is not intended that the specific description shall constitute a limitation. No limita tion is intended except such as are required by the prior art or stated in the accompanyin claims.
I claim as my invention:
1. In a coil supporting device, a pair of shouldered members positioned with their shoulders in opposite directions, and a coil supported on said members intermediate said shoulders.
2. In combination a cellular coil, supporting strips extending through one of the cells thereof, each of said strips having shoulders,
the shoulders being at opposite extremities of the cell, whereby "movement of. the coil axially of the strips is prevented.
3. In combination, a cellular coil, a .supporting strip for said coil, said strip having a shank of a Width approximately equal to the interior Width of a cell of said coil, an enlarged portion on said strip and shoulders on said strip at the junction of said enlarged portion having a width greater than the width of a cell.
4. In combination, a cellular coil, a supporting strip for said coil, said'strip having a shank of a width approximately equal to the interior width of a cell of said coil, an
enlarged portion on said strip, shoulders on width ofa cell, a tennon providing shoulders at the opposite end of said enlarged portion and a: recessed member cooperating with said 1 tennon for supporting said 0011.
5. In a coil support, a base, a pairof brackets mounted on said base, coil-supportof cellular spaces as the turns advance around the coil, and a pair of oppositely shouldered insulated supporting members arranged in one of said cellular spaces, where 'byaxial movements of the coil are prevented by the shoulder.
7 coil-supporting device comprising in combination a base-member provided with a pair of resilient-uprights, a pair of relatively I rigid elements supported in parallel relation by said uprights, meanscarried by'each of PAUL M. HENGSTENBERG.
