Description
Rammeantenne med ferromagnetisk kjerne, særlig ferritstavantenne. Frame antenna with ferromagnetic core, especially ferrite rod antenna.
Foreliggende oppfinnelse angår en The present invention relates to a
rammeantenne med ferromagnetisk kjerne, særlig ferritstavantenne som er bygget frame antenna with ferromagnetic core, especially ferrite rod antenna that has been built
opp av mekanisk sammenholdte enkeltstaver. up of mechanically joined individual rods.
Ved en kjent rammeantenne av At a known frame antenna of
denne art med ferromagnetisk kjerne, er this species with a ferromagnetic core, is
kjernen sammensatt av flere etter hinannen anordnede deler, idet det vanskelig lar the core composed of several successively arranged parts, as it hardly allows
seg gjøre å fremstille større ferromagnetiske staver med konstant tykkelse, ensarte-de mekaniske egenskaper og samme fast-het. Ved den kjente oppdeling av kjernen possible to produce larger ferromagnetic rods with constant thickness, uniform mechanical properties and the same firmness. By the known division of the core
unngås dessuten vanskeligheter ved opp-bygging av presseverktøy, og kjernen blir difficulties are also avoided when building up press tools, and the core remains
billigere. cheaper.
Som følge av sine gode elektriske egenskaper utføres de forromagnetiske kjerner As a result of their good electrical properties, they are made forromagnetic cores
i den senere tid ofte som lange staver, men in recent times often as long spells, but
disse lange kjerner er særlig sterkt utsatt these long cores are particularly strongly exposed
for mekaniske påvirkninger. Ferromagnetiske staver som brukes i kjøretøy utsettes for mechanical influences. Ferromagnetic rods used in vehicles are exposed
for store mekaniske momenter som kan for large mechanical moments that can
føre til at kjernen brekker. Staven av ferromagnetisk materiale vil også utsettes for cause the core to break. The rod of ferromagnetic material will also be exposed to
store mekaniske påvirkninger, hvis den major mechanical influences, if the
bare er innspent i dreieanordningen i midten og dreies hurtig. I det minste vil der ved is only clamped in the turning device in the middle and is turned quickly. At least there will be wood
slike påvirkninger kunne oppstå en gjen-sidig gnidning mellom kjernedeler som such influences could result in a mutual friction between core parts which
støter sammen. collide.
Problemstillingen ved konstruksjonen The problem of construction
av rammeantenne ifølge oppfinnelsen er of frame antenna according to the invention is
en annen enn ved de kjente rammeantenner, idet oppfinnelsen tar sikte på å skaffe different from the known frame antennas, as the invention aims to provide
en rammeantenne hvis magnetiske kjerne a frame antenna whose magnetic core
riktignok er sammensatt av staver, men admittedly is composed of syllables, but
oppbygget slik at kjernen oppviser en viss structured so that the core exhibits a certain
elastisitet og dermed ikke har så lett for å briste som følge av opptredende momenter, elasticity and thus not prone to breaking as a result of occurring moments,
eller vil bevirke gnidning mellom elementer som støter til hinannen. or will cause friction between elements that collide with each other.
Rammeantenne ifølge oppfinnelsen ut-merker seg ved at der for økning av den ferromagnetiske kjernes elastisitet og dermed dens bruddsikkerhet, mellom to og to på hinannen følgende ferromagnetiske enkeltstaver er lagt skiver av elastisk materiale. The frame antenna according to the invention is distinguished by the fact that, in order to increase the ferromagnetic core's elasticity and thus its resistance to breakage, discs of elastic material are placed between two successive ferromagnetic individual rods.
En rammeantennekjerne i henhold til oppfinnelsen har ikke de ulemper som de kjente kjerner. Dens mekaniske motstands-dyktighet er vesentlig bedre enn ved de kjente konstruksjoner, og stikk imot hva man kunne vente når der legges skiver av elastisk materiale imellom to delstaver, lot det seg eksperimentelt påvise at feltlinje-forløpet praktisk talt forble upåvirket av de mellomliggende skiver. Dermed behol-der anordningen de samme gode elektriske egenskaper som rammeantenner av annen art har, selvom dette egentlig ikke var å vente. A frame antenna core according to the invention does not have the disadvantages of the known cores. Its mechanical resistance is significantly better than that of the known constructions, and contrary to what one might expect when disks of elastic material are placed between two sub-rods, it was experimentally demonstrated that the course of the field line remained practically unaffected by the intermediate disks. Thus, the device retains the same good electrical properties as frame antennas of other kinds, although this was not really to be expected.
Ifølge en foretrukket utførelse av opp-finelsen forsynes enkeltstavene og de mellomliggende skiver av elastisk materiale med en aksial boring for en bolt med med-ier til å holde de enkelte elementer sammen. Ferritstaver leveres fra fabrikantenes side allerede med aksialboring. Denne an-ordning er særlig enkel og billig. Bortsett fra dette, bevirker boringen en besparelse av materialet. Den derav følgende reduk-sjon av mengden av ferromagnetisk materiale og tilstedeværelsen av en metallisk stav i boringen er praktisk talt uten inn-flytelse på antennens elektriske egenskaper, da stavens sentrale deler som følge av at de magnetiske feltlinjer ved høye fre-kvenser trekkes mot kantsonene, i alle tilfelle være feltfri og således ikke ta del i magnetiserings- og induksjonsprosessene. Fortrinnsvis utføres den bolt som er ført gjennom den langsgående boring, av messing, mens skivene utføres av gummi. Særlig enkel blir konstruksjonen når bolten som er ført gjennom den sentrale boring, stikker noe ut forbi endene av de ytterste stavelementer, slik at disse ender kan forsynes med gjenger og muttere. Bolten kan imidlertid også utføres som et rør med samme lengde som den totale ferromagnetiske stav, idet røret er forsynt med inn-vendige gjenger for innsetning av skruer. I begge tilfelle legges der hensiktsmessig også skiver av elastisk materiale under mutterne hhv. skruhodene. According to a preferred embodiment of the invention, the individual rods and the intermediate discs of elastic material are provided with an axial bore for a bolt with media to hold the individual elements together. Ferrite rods are supplied by the manufacturers already with axial drilling. This arrangement is particularly simple and cheap. Apart from this, the drilling causes a saving of the material. The resulting reduction in the amount of ferromagnetic material and the presence of a metallic rod in the bore is practically without influence on the antenna's electrical properties, as the central parts of the rod are drawn towards the edge zones as a result of the magnetic field lines at high frequencies , in any case be field-free and thus do not take part in the magnetization and induction processes. Preferably, the bolt which is guided through the longitudinal bore is made of brass, while the washers are made of rubber. The construction becomes particularly simple when the bolt, which is passed through the central bore, protrudes somewhat beyond the ends of the outermost rod elements, so that these ends can be provided with threads and nuts. However, the bolt can also be made as a tube with the same length as the total ferromagnetic rod, the tube being provided with internal threads for the insertion of screws. In both cases, discs of elastic material are also suitably placed under the nuts or the screw heads.
En foretrukket utførelse av rammeantenne ifølge oppfinnelsen er gjengitt på tegningen som viser en stav som er sammensatt av enkeltstaver 1 med mellomliggende skiver 2. Elementene er utført med senterboring og sammen med skivene tredd utenpå en metallbolt 3, f. eks. av messing, hvis ender er gjenget og påsatt muttere 4 med gummiskiver 2 som under-lag. A preferred embodiment of the frame antenna according to the invention is shown in the drawing which shows a rod which is composed of individual rods 1 with intermediate discs 2. The elements are made with a center hole and together with the discs threaded on the outside of a metal bolt 3, e.g. of brass, whose ends are threaded and fitted with nuts 4 with rubber washers 2 as a sub-layer.
På midten av den sammensatte stav er anordnet en vikling 5. I stedet for en eneste vikling 5 kan der være anordnet flere viklinger som er jevnt fordelt over hele stavens lengde. A winding 5 is arranged in the middle of the composite rod. Instead of a single winding 5, several windings can be arranged which are evenly distributed over the entire length of the rod.
Rammeantenne ifølge oppfinnelsen Frame antenna according to the invention
kan også anvendes som en del av en kors-ramme som f. eks. kan utføres ved at to rammeantenner ifølge oppfinnelsen anordnes i kryss, eller også slik at fire rammeantenner ifølge oppfinnelsen anordnes langs hver sin side av et kvadrat. can also be used as part of a cross frame such as can be carried out by two frame antennas according to the invention being arranged in a cross, or also so that four frame antennas according to the invention are arranged along each side of a square.
