Description

Den foreliggende oppfinnelse vedrører en anordning ved akkuniulatorbatteri for å forhindre utilsiktet berøring med en oppragende endepolbolt. The present invention relates to a device for an accumulator battery to prevent accidental contact with a protruding end terminal bolt.

Hensikten med oppfinnelsen er å tilveiebringe en spesiell enkel og billig, i beskyttelseshenseende tilfreds-stillende anordning av ovennevnte slag. The purpose of the invention is to provide a particularly simple and cheap, in terms of protection satisfactory device of the above type.

I nevnte hensikt foreslås ifølge' oppfinnelsen at endepolbolten er forsynt med minst en, hovedsakelig i dennes aksialretning forløpende utsparing og at et av elektrisk isolerende materiale bestående endepolboltberøringsbeskyttelse, som dekker i det minste endepolboltens overside, men frilegger dens mantelflate, fastholdes på endepolbolten ved hjelp av minst en fra berøringsbeskyttelsen nedragende og i endepolboltens utsparing inngripende tapp. Gjennom dette arrangement sikres ikke bare med enkle midler en effektiv beskyttelse mot kortslutning ved samtidig berøring av batteriets to endepolbolter eller den positive endepolbolt og jord med for eksempel et elektrisk ledende verktøy, men det oppnås også ved måten for endepolboltens anbringelse en ikke uvesentlig innsparing av det forholdsvis kostbare polboltmaterialet. For this purpose, according to the invention, it is proposed that the end pole bolt is provided with at least one, mainly in its axial direction continuous recess and that an end pole bolt contact protection consisting of electrically insulating material, which covers at least the upper side of the end pole bolt, but exposes its mantle surface, is held onto the end pole bolt by means of at least one pin extending downwards from the contact protection and engaging in the recess of the end pole bolt. Through this arrangement, not only is effective protection against short-circuit ensured by simple means by simultaneous touching of the battery's two end terminal bolts or the positive end terminal bolt and earth with, for example, an electrically conductive tool, but a not inconsiderable saving of the the relatively expensive pole bolt material.

Med fordel er hver endepolbolt forsynt med en eneste sentral utsparing som er utformet i forbindelse med støpingen av den blydetalj som omfattes av endepolbolten, hvorved anbringelsen av endepolboltberøringsbeskyttelsen lettes og endepolboltens mantelflate for kontakt med et strømavtag-ningsorgan, forblir intakt. Advantageously, each end pole bolt is provided with a single central recess which is designed in connection with the casting of the lead detail comprised by the end pole bolt, whereby the placement of the end pole bolt contact protection is facilitated and the end pole bolt's mantle surface for contact with a current collector remains intact.

Endepolboltberøringsbeskyttelsens tapp er hensiktsmessig rørformet og forsynt med aksielle slisser, hvorved oppnås en innsparing av nevnte isolerende materiale, samtidig som toleransékravene til tapp og utsparing kan settes forholdsvis lave som følge av den gjennom slissingen av tappen økte ettergivelighet og tilpassbarhet. The pin of the end pole bolt contact protection is suitably tubular and provided with axial slots, whereby a saving of said insulating material is achieved, while at the same time the tolerance requirements for pin and recess can be set relatively low as a result of the increased flexibility and adaptability through the slotting of the pin.

En spesiell fordel ved berøringsbeskyttelsen erA particular advantage of the touch protection is

at den ved tappens ene ende framviser et flatt hode med en utstrekning som hovedsakelig stemmer overens med utstrekningen av endepolboltens overside. En slik utformet beskyttelse er videre billig og enkel med hensyn til sin utforming og gir that at one end of the pin it presents a flat head with an extent that mainly corresponds to the extent of the upper side of the end pole bolt. Such designed protection is furthermore cheap and simple in terms of its design and performance

samtidig en for de fleste forhold fullgod beskyttelse. Videre stilles små krav til sluttbearbeidelsen av endepolboltens endeflate. at the same time, for most conditions, adequate protection. Furthermore, small requirements are placed on the final processing of the end surface of the end pole bolt.

Den vanlige markering for å vise den aktuelle endepolbolts polaritet, f.eks. i form av en farvet ring ved endepolboltens basis, kan unngås hvis berøringsbeskyttelsen i samsvar med et fordelaktig trekk ved oppfinnelsen gis en farve som angir endepolboltens polaritet og/eller på sin fra tappens vendte side forsynes med et tegn som angir endepolboltens polaritet, f.eks. et reliefftegn. The usual marking to show the polarity of the terminal bolt in question, e.g. in the form of a colored ring at the end pole bolt's base, can be avoided if, in accordance with an advantageous feature of the invention, the touch protection is given a color that indicates the end pole bolt's polarity and/or on its side facing away from the pin is provided with a sign that indicates the end pole bolt's polarity, e.g. . a relief sign.

Oppfinnelsen skal beskrives i det følgende med henvisning til en i tegningen vist foretrukken utførelse .av denne. Tegningen viser i The invention shall be described in the following with reference to a preferred embodiment shown in the drawing. The drawing shows i

figur 1 et perspektivriss av et parti av et akkumulatorbatteri med en i samsvar med oppfinnelsen berøringsbeskyttet polbolt, Figure 1 is a perspective view of part of an accumulator battery with a contact-protected terminal bolt in accordance with the invention,

figur 2 et aksialsnitt gjennom endepolbolten og berøringsbeskyttelsen ifølge figur 1, og figure 2 an axial section through the end pole bolt and the contact protection according to figure 1, and

figur 3 et perspektivriss av berøringsbeskyttelsen ifølge figur 1 og 2. Figure 3 is a perspective view of the touch protection according to Figures 1 and 2.

I figur 1 vises ved 10 et øvre hjørneparti av et akkumulatorbatteri og ved 11 den ene av batteriets oppragende endepolbolter. Endepolbolten 11 utgjøres i det viste eksempel, batteriets positive endepolbolt og er forsynt med en generelt med 12 betegnet beskyttelse for å forhindre utilsiktet berøring av endepolboltens materiale. Denne beskyttelse 12, som også vises i figur 2 og 3, består av et elektrisk isolerende materiale, f.eks. et hensiktsmessig plastmateriale, og framviser et flatt hode 13 samt en sentralt fra dettes underside nedragende tapp 14. In Figure 1, an upper corner part of an accumulator battery is shown at 10 and at 11 one of the battery's protruding terminal bolts. The terminal bolt 11 is, in the example shown, the battery's positive terminal bolt and is provided with a protection generally denoted by 12 to prevent accidental contact with the material of the terminal bolt. This protection 12, which is also shown in figures 2 and 3, consists of an electrically insulating material, e.g. a suitable plastic material, and presents a flat head 13 as well as a central downwards pin 14 from its underside.

For berøringsbeskyttelsens 12 anbringelse på endepolbolten 11 er, som tydelig vist i figur 2, den sistnevnte forsynt med en sentral, glattvegget utsparing 15, hvori tappen 14 er innskjøvet og fastholdes ved friksjon. Tappen 14 er rørformet og aksielt slisset, slik som vist ved 16, hvorved den får mulighet til å tilpasse seg utsparingens 15 form slik at presisjonskravene for utsparing 15 og tapp 14 blir forholdsvis For the attachment of the contact protection 12 to the end pole bolt 11, as clearly shown in Figure 2, the latter is provided with a central, smooth-walled recess 15, in which the pin 14 is inserted and held by friction. The pin 14 is tubular and axially slotted, as shown at 16, whereby it has the opportunity to adapt to the shape of the recess 15 so that the precision requirements for recess 15 and pin 14 are relatively

små. small.

Med berøringsbeskyttelsen 12 anbragt i stillingWith the touch guard 12 placed in position

på endepolbolten 11 ligger hodet 13 med sin underside mot endepolboltens øvre endeflate og dekker denne. Herved oppnås en god beskyttelse mot kortslutning forårsaket av at man ved hjelp av f.eks. et verktøy av elektrisk ledende materiale, samtidig berører endepolbolten 11 og en annen del som er jordet eller framviser en motsatt polaritet, f.eks. batteriets negative endepolbolt, hvilken også hensiktsmessig er forsynt med polboltbeskyttelse på samme måte som er beskrevet for den positive endepolbolt 12. on the end pole bolt 11, the head 13 lies with its underside against the end pole bolt's upper end surface and covers this. This achieves good protection against short circuits caused by using e.g. a tool of electrically conductive material, simultaneously touching the end pole bolt 11 and another part which is grounded or exhibits an opposite polarity, e.g. the battery's negative end pole bolt, which is also suitably provided with pole bolt protection in the same way as described for the positive end pole bolt 12.

Berøringsbeskyttelsens 12 hode 13 framviser et reliefftegn 17, som angir endepolboltens 12 polaritet eller eventuelt en farve som viser polariteten. The head 13 of the contact protection 12 displays a relief sign 17, which indicates the polarity of the end pole bolt 12 or possibly a color that shows the polarity.

Oppfinnelsen er ikke begrenset til det ovenforThe invention is not limited to the above

med henvisning til tegningen, beskrevne eksempel, men kan selvsagt utføres på mange andre måter innen rammen for den i patentkravene angitte oppfinnelsestanke. with reference to the drawing, described example, but can of course be carried out in many other ways within the scope of the inventive idea stated in the patent claims.
