Description

Wynalazek niniejszy dotyczy lampy katodowej i ma na celu ochrone lampy przed zaklóceniami, powstajacemi pod¬ czas jej pracy wskutek niedostateczniej izolacji pomiedzy poszczególnemi czescia¬ mi lampy, które podczas pracy lampy po¬ siadaja rózne potencjaly.Ustalono, ze podczas pracy elektrycz¬ nych lamp katodowych pomiedzy dopro¬ wadzeniami elektrod moga powstac drogi elektryczne, wytwarzajace sie wskutek osiadania czasteczek metalowych w miej¬ scu splaszczenia slupka lampy. Tak np, w miejscu tern mógl osiadac magnez, któ¬ ry odparowywano w lampie celem uzyska¬ nia nalezytej prózni. W celu utrudnienia mozliwosci powstawania podobnych zakló¬ cen proponowano np. umieszczac dopro¬ wadzenia jak najdalej od siebie, nadajac niesplaszczonemu miejscu slupka jak naj¬ wieksze wymiary. Wobec jednakze ograni¬ czonych wymiarów lampy metoda ta nie zawsze daje pozadane wyniki.Lampa katodowa wedliig wynalazku niniejszego posiada jedna lub kilka oslon, pokrywajacych calkowicie lub czesciowo izolujace laczniki, znajdujace sie pomie¬ dzy poszczególnemi czesciami lampy, któ¬ re podczas pracy jej posiadaja rózne po¬ tencjaly. Mozna wewnatrz lampy umie¬ scic jeden lub kilka pasków ochronnych, które pokrywaja calkowicie lub czescio-wo podluzne strony splaszczonego miejsca slupka lampy./^R^sM ochronne moga byc w tytópf^yp^tó przymocowane wedlug wynalazku do drutu podporowego lub dru¬ tu, doprowadzajacego prad do jednej z elektrod.Przyklad wykonania wynalazku przed¬ stawiono na rysunku. W praktyce okazalo sie, ze ta wlasnie odmiana wykonania po¬ siada szczególne zalety zarówno pod wzgle¬ dem celowosci, jak i latwosci wykonania.Fig. 1 przedstawia w widoku zprzodu slupek lampy katodowej wedlug wynalaz¬ ku lacznie z elektrodami, przymocowa- nemi do niego, zas fig. 2 — widok boczny tego slupka.Cyfra / oznacza rurke kolnierzowa slupka, w której splaszczeniu wtopione sa druty podpierajace i druty, doprowadza¬ jace prad do elektrod, cyfra 2 — anode, 3 — siatke, 5 — drut podpierajacy anode, a 4 — drut doprowadzajacy prad do ano¬ dy. Do drutów 4 i 5 przymocowana jest oslona 6, wykonana z odpowiedniego ma- terjalu, np. z niklu. Jezeli oslony wykona¬ ne sa z metalu, to winny sie one naturalnie znajdowac w okreslonej, najwlasciwiej niewielkiej odleglosci od drutów, dopro¬ wadzajacych prad. Z fig. 2 wynika, ze oslony 6 ochraniaja nalezycie miejsce splaszczone slupka, zapobiegajac w ten sposób osiadaniu tam czasteczek metalu, dzieki czemu unika sie zwarc. PL PLThis invention concerns a cathode-ray tube and is intended to protect the tube from interference generated during its operation due to insufficient insulation between individual tube parts, which are at different potentials during operation. It was determined that during the operation of electric cathode-ray tubes, electrical paths can form between the electrode leads, generated by the deposition of metal particles in the flattened area of the tube's column. For example, magnesium could deposit in this area, which was evaporated in the tube to achieve the required vacuum. To minimize the possibility of such interference, it was proposed to place the leads as far apart as possible, making the non-flattened area of the column as large as possible. However, due to the limited dimensions of the lamp, this method does not always produce the desired results. The cathode ray tube according to the present invention has one or more covers that completely or partially cover the insulating connectors located between the individual parts of the lamp, which are at different potentials during operation. One or more protective strips can be placed inside the lamp, completely or partially covering the longitudinal sides of the flattened area of the lamp post. The protective strips can be attached in accordance with the invention to a supporting wire or a wire that conducts current to one of the electrodes. An example of the invention is shown in the drawing. In practice, this particular embodiment has proven to have particular advantages both in terms of expediency and ease of manufacture. Fig. Figure 1 shows a front view of the post of a cathode ray tube according to the invention, together with the electrodes attached thereto, while Figure 2 shows a side view of this post. The number / denotes the flanged tube of the post, in the flattening of which are embedded the support wires and the wires that conduct current to the electrodes; the number 2 denotes the anode; 3 denotes the grid; 5 denotes the wire supporting the anode; and 4 denotes the wire that conducts current to the anode. A shield 6 made of a suitable material, e.g., nickel, is attached to wires 4 and 5. If the shields are made of metal, they should naturally be located at a certain, preferably short, distance from the wires that conduct current. From Fig. 2 it can be seen that the covers 6 adequately protect the flattened area of the post, thus preventing metal particles from settling there, thus avoiding short circuits.
