Description
Fremgangsmåte til fremstilling av et galvanisk primærelement. Method for manufacturing a galvanic primary element.
Oppfinnelsen angår en fremgangsmåte til fremstilling av et galvanisk primærelement som har et ytre hylster av isolerende og for elektrolytt ugj enomtrewgelig ma-teriale, fortrinnsvis kunststoff. The invention relates to a method for producing a galvanic primary element which has an outer casing of insulating and electrolyte-impermeable material, preferably plastic.
I en mindre kjent konstruksjon blir In a less well-known construction becomes
den ferdige celle skjøvet inn i et hus av kunststoff som deretter brettes om ved bunnen ved hjelp av et oppvarmet stem-pel. En annen utførelsesform består deri at det over en normalt fremstilt celle trek-kes en strukket kunststoffslange, hvis the finished cell is pushed into a plastic housing which is then folded over at the bottom using a heated stamp. Another embodiment consists in that a stretched plastic hose is drawn over a normally produced cell, if
spenninger deretter utløses ved passende temperatur, slik at den legger seg tett an mot cellen. Ingen av disse konstruksjoner gir imidlertid en tilforlatelig beskyttelse mot uttreden av elektrolytt fra elementet, da den blotte omlegging av kunststoffman-telen ved bunnen ikke gir noen tilstrekkelig tetthet. voltages are then released at the appropriate temperature, so that it adheres tightly to the cell. None of these constructions, however, provide acceptable protection against the escape of electrolyte from the element, as the mere repositioning of the plastic jacket at the bottom does not provide sufficient tightness.
Videre er det blitt foreslått et element Furthermore, an element has been proposed
hvor cellen sitter i et kunststoffbegeir, i hvis bunn det er innsprøytet en metall-skive. Den positive avledning er da inn-sprøytet i et kunststoffdeksel som enten blir sveiset eller klebet sammen med begeret. Heller ikke denne utførelse byr abso - lutt sikkerhet mot uttreden av elektrolytt, where the cell sits in a plastic cup, in the bottom of which a metal disk has been injected. The positive lead is then injected into a plastic cover which is either welded or glued together with the cup. Nor does this design offer absolute security against the escape of electrolyte,
de erfaringsmessig forbindelsen mellom metall og kunststoff ikke er fullstendig tett. Som videre ulempe ved denne konstruksjon er å nevne den omstendelige og derfor kostbare fremstilling. The experience shows that the connection between metal and plastic is not completely tight. A further disadvantage of this construction is the time-consuming and therefore expensive manufacture.
Ved en videre konstruksjon er det i In the case of a further construction, it is i
en kunststoffmantel som omgir cellen innleiret i dennes bunn en nagle som tjener som negativ sitrømavleder. Også detite ele- a plastic sheath that surrounds the cell embedded in its bottom a rivet that serves as a negative lemon arrester. Also this ele-
ment er kostbart å fremstille og har dess-uten den ulempe at på grunn av den lille berøringsflate mellom naglen og sinkbege-ret er den elektriske kontakt mellom disse to deler mangelfull. ment is expensive to produce and also has the disadvantage that due to the small contact surface between the rivet and the zinc cup, the electrical contact between these two parts is inadequate.
Det var den foreliggende oppfinnelses oppgave å unngå alle de mangler som hef-ter ved de tidligere konstruksjoner og med sikkerhet å hindre at elektrolytten trer ut av cellen og beskadiger det omgivende hus eller andre deler. Denne oppgave blir i henhold til oppfinnelsen løst derved at en ved bunnen av den negative, fortrinnsvis av sink bestående elektrode anbrakt ansats er føint gjennom en åpning i kunst-stoffomhyllingen og i likhet med en naglebolt er stuket sammen med omhyllingen under fullstendig tetting. Ved et element i henhold til oppfinnelsen blir altså den ytre omhylling bare gjennombrutt av ansatsen, som kan gis en meget liten dia-meter. Randfugien mellom ansats og hylster har tilsvarende kort lengde og holder derfor ,godt tett. Allikevel fås det god elek-trisk kontakt mellom den negative elektrode og en ytre strømavleder, fordi at det på grunn av at ansatsen og elektroden består av ett stykke, ikke kan opptre noen overgangsmotstander mellom disse deler. It was the task of the present invention to avoid all the shortcomings associated with the previous constructions and to prevent the electrolyte from leaking out of the cell and damaging the surrounding housing or other parts with certainty. According to the invention, this task is solved in that an attachment placed at the bottom of the negative electrode, preferably consisting of zinc, is inserted through an opening in the plastic casing and, like a rivet, is stuck together with the casing under complete sealing. With an element according to the invention, the outer casing is thus only broken through by the shoulder, which can be given a very small diameter. The edge joint between the collar and sleeve has a correspondingly short length and therefore holds tightly. Nevertheless, good electrical contact is obtained between the negative electrode and an external current conductor, because due to the fact that the attachment and the electrode consist of one piece, no transition resistances can occur between these parts.
Som videre fordel ved en celle i hen^ hold til oppfinnelsen må nevnes at denne er lett å fremstille. Det er uten videre mu-lig, f. eks. når det gjelder en begerformig negativ elektrode, å sprøyts ansatsen sammen med iSielve begeret i en arbeidsoperasjon. I en neste arbeidsoperasjon blir elektroden satt inn i et kunststoffbegeir og naglet sammen med dette. Den videre fremstilling av elementet skjer deretter på vanlig måte. As a further advantage of a cell according to the invention, it must be mentioned that it is easy to produce. It is without further ado possible, e.g. in the case of a cup-shaped negative electrode, to spray the approach together with the cup itself in one work operation. In a subsequent work operation, the electrode is inserted into a plastic beaker and riveted together with this. The further production of the element then takes place in the usual way.
Tegningene viser noen mulige utførel-sesformer av et primærelement i henhold til oppfinnelsen. Fig. 1 viser et tørrelement av vanlig art med sentralt anordnet positiv strøm-avleder b, fortrinnsvis en kullstift, depola-risatormasse og elektrolytt c, som er anbrakt i et heger d av elektronegativt metall, fortrinnsvis sink. Metallbegeret d er utvendig omgitt av et beger e av isolerende for elektrolytt ugjennomtrengelig materialer, fortrinnsvis kunststoff, hvilket beger er høyere enn metallbegeret d. Oventil eir elementet avsluttet av et deksel i som består av det samme matieriaie som begeret e og er tett forbundet eksempelvis sveiset eller klebet sammen med dette. I dekslet er det tett innleiret, fortrinnsvis innsprøytet en plusskontaktkappe a. Over depolarisatormassen og elektrolytt c er det anordnet et utvidelsesrom m for elektrolytten. Metallbegeret d har ved bunnen en ansats h, som er ført gjennom begeret e og stuket sammen i likhet med en naglebolt. Fig. 2—4 viser andre fordelaktige ut-førelsesf ormer. The drawings show some possible embodiments of a primary element according to the invention. Fig. 1 shows a drying element of a common type with a centrally arranged positive current diverter b, preferably a carbon pin, depolarizer mass and electrolyte c, which is placed in a heger d of electronegative metal, preferably zinc. The metal cup d is surrounded on the outside by a cup e made of insulating, electrolyte-impermeable materials, preferably plastic, which cup is higher than the metal cup d. Above, the element is finished by a cover i which consists of the same material as the cup e and is tightly connected, for example welded or glued together with this. A plus contact jacket a is tightly embedded in the cover, preferably injected. Above the depolarizer mass and electrolyte c, an expansion space m for the electrolyte is arranged. The metal cup d has a shoulder h at the bottom, which is passed through the cup e and pushed together like a rivet. Fig. 2-4 show other advantageous embodiments.
I fig. 2 holder den sammenistukede ansats h en kontaktskive g fast på elementets bunn. I fig. 3 er det mellom bunnen av metallbegeret d og det ytre beger e anordnet en ringformet tetningsskive f, fortrinnsvis av gummi, som tetter gjennomførings-åpningen for ansatsen h gjennom begeret e ennå en gang mot elektrolytt-uttreden. I fig. 4 omgir en tetning 1 av et for elektrolytt gjennomtrengelig, isolerende ma-teriale, fortrinnsvis kunststoff, som i det vesentlige har form av en hul sylinder, den gjennom utvidelsesrommet førte del av den positive strømavleder to, og skiller denne fra utvidelsesrommet m. Samtidig tryk-ker foten k på depolarisatormassen c og fastholder denne i dens stilling i elementet. In fig. 2, the folded shoulder h holds a contact disc g firmly on the bottom of the element. In fig. 3, an annular sealing disc f, preferably made of rubber, is arranged between the bottom of the metal cup d and the outer cup e, which seals the passage opening for the attachment h through the cup e once again against electrolyte exit. In fig. 4 surrounds a seal 1 of an electrolyte-permeable, insulating material, preferably synthetic material, which essentially has the shape of a hollow cylinder, the part of the positive current conductor 2 that passes through the expansion space, and separates this from the expansion space m. Simultaneous pressure -ker the foot k on the depolarizer mass c and maintains this in its position in the element.
Videre har det vist seg å være fordel-aktig å gjøre utvidelsesrommets m størrelse minst lik volumet av det ubrukte elements elektrolyttpasta. Det har nemlig vist seg at ved kortslutning av en monocelle ut-vider dennes elektroluttvolum seg i løpet av tone dager ta! det dobbelte, men forblir deretter konstant. Hvis man i elementet sørger for et tilstrekkelig stort utvidelsesrom for denne elektirolyttvolumøkning, kan det ikke opptre noe øket av innvendige trykk som kan føre til at elementets ytter-hylse blir revet opp og elektrolytten kom-mer ut. Heller ikke kan hele elementet svelle. Furthermore, it has been shown to be advantageous to make the size of the expansion space m at least equal to the volume of the unused element's electrolyte paste. It has been shown that when a monocell is short-circuited, its electrolyte volume expands over the course of a ton of days! twice that, but then remains constant. If a sufficiently large expansion space is provided in the element for this electrolyte volume increase, no increase in internal pressure can occur which could cause the element's outer sleeve to be torn open and the electrolyte to come out. Nor can the entire element swell.
