Description
i 151426in 151426
Den foreliggende opfindelse angår en polboltgennem-føring i låget til kassen på en elektrisk akkumulator, hvor polbolten i området ved gennemføringen gennem låget omfattes af en i dette tætnende anbragt bøsning af plast og hvor en indsats bestående af en blybøsning og et plastlegeme, som udvendigt omgiver blybøsningen, er anbragt mellem plastbøsningen og polboltens væg med blybøsningen tætnende mod denne væg.The present invention relates to a pole bolt penetration in the lid of the box of an electric accumulator, wherein the pole bolt in the area of the passage through the lid is comprised of a sleeve of plastic arranged therein and in which an insert consisting of a lead sleeve and a plastic body which surrounds the outside the lead bushing, is placed between the plastic bushing and the wall of the pole bolt with the lead bushing sealing against this wall.
En sådan polboltgennemføring er tidligere kendt fra SE-patentansøgning nr. 7602230-8 (svarer til US PS 4.075.368). Ansøgningen angår især en forbedring af strømafledningen, især ved området ved endepolen, en besparelse af bly, samt en forenkling af montagen og en reduktion af konstruktionshøjden. En ulempe ved den kendte akkumulator er, at polbolten og følgelig tillige elektrodepladerne er stift forbundne med akkumulatorens låg. Under akkumulatorens drift kan de positive elektrodeplader vise tilbøjelighed til at udvide sig i vertikal retning, hvorved polbolten løftes op og kan forårsage skader på batterilåget osv. Disse skader kan danne lækager for elektrolytten.Such a pole bolt bushing is previously known from SE Patent Application No. 7602230-8 (corresponding to US PS 4,075,368). The application relates in particular to an improvement of the current drain, especially at the area at the end pole, a saving of lead, as well as a simplification of the assembly and a reduction of the construction height. A disadvantage of the known accumulator is that the pole bolt and consequently also the electrode plates are rigidly connected to the lid of the accumulator. During operation of the accumulator, the positive electrode plates may tend to expand in the vertical direction, thereby lifting the pole bolt and causing damage to the battery cover, etc. These damages may cause leaks to the electrolyte.
Det hovedsagelige formål med opfindelsen er at eliminere eller væsentligt at reducere ulempen ved den kendte polbolt, hvilket omfatter frembringelse af en polboltgennemføring, ved hvilken det fordres, at polbolten skal være bevægelig i aksial retning, og tillige i en vis udstrækning i radial retning i forhold til låget, samtidig med at der opretholdes en effektiv tætning mellem polboltens overflade og akkumulatorens låg.The main object of the invention is to eliminate or substantially reduce the disadvantage of the known pole bolt, which comprises producing a pole bolt bushing, in which it is required that the pole bolt must be movable in axial direction, and also to a certain extent in radial direction relative to to the lid, while maintaining an effective seal between the surface of the pole bolt and the lid of the accumulator.
Dette opnås ifølge opfindelsen ved, at polbolten er ejendommelig ved det i den kendetegnende del af krav 1 angivne .This is achieved according to the invention in that the pole bolt is characterized by what is stated in the characterizing part of claim 1.
Ifølge opfindelsen løses opgaven ved, at den aksiale og radiale bevægelse styres og reguleres ved hjælp af indsatsen, medens fordringen til tætningen opfyldes ved anbringelse af en tætningsring, der kan fremstilles af passende blødt materiale. Polgennemføringen indeholder altså to separate organer med principielt uforenelige egenskaber, som er udvalgt med hensyn til de tilstræbte egenskaber. Eventu- 151426' 2 elle radiale påvirkninger i polbolten kan på den måde via indsatsens yderside fordeles over en større modflade i bøsningen i låget, hvorved påvirkningen bliver mindre.According to the invention, the object is solved by controlling and regulating the axial and radial movement by means of the insert, while the requirement for the seal is fulfilled by placing a sealing ring which can be made of suitable soft material. The pole bushing thus contains two separate bodies with fundamentally incompatible properties, which have been selected with regard to the desired properties. Any radial influences in the pole bolt can thus be distributed via the outside of the insert over a larger counter surface in the bushing in the lid, whereby the influence becomes smaller.
Ifølge en foretrukken udførelsesform i henhold til opfindelsen er tætningsringen en såkaldt O-ring.According to a preferred embodiment according to the invention, the sealing ring is a so-called O-ring.
Opfindelsen skal i det følgende beskrives nærmere under henvisning til tegningen, hvor fig. 1 viser en første udførelsesform for opfindelsen vist forfra i snit, fig. 2 viser udførelsesformen på fig. 1 set ovenfra, fig. 3 viser en anden udførelsesform for opfindelsen i snit forfra og fig. 4 viser udfør elsesf omen på fig. 3 set ovenfra.The invention will be described in more detail below with reference to the drawing, in which fig. 1 shows a first embodiment of the invention shown in front view in section, fig. 2 shows the embodiment of fig. 1 seen from above, fig. Fig. 3 shows another embodiment of the invention in front view and fig. 4 shows the embodiment of FIG. 3 seen from above.
De samme dele på figurerne er betegnet med samme henvisningsnumre.The same parts of the figures are denoted by the same reference numerals.
På fig. 1 og 2 vises en blygennemføring for en polbolt i et akkumulatorbatteri af blysyretypen. Gennemføringen omfatter et cylindrisk hylster 1, som er beregnet til at blive indført i et rundt hul i akkumulatorbatteriets låg, idet batteriet ikke er vist på tegningen. Hylsteret har en øvre flange 2, der befinder sig i berøring med oversiden af batteriets låg, og en nedre radialt indadrettet flange 3 med skarp kant, som tjener det formål at muliggøre draaiing af elektrolyt i overensstemmelse med hvad der vil blive beskrevet i det følgende.In fig. 1 and 2 show a lead lead-through for a pole bolt in a lead-acid type accumulator battery. The bushing comprises a cylindrical casing 1, which is intended to be inserted into a round hole in the lid of the accumulator battery, the battery not being shown in the drawing. The casing has an upper flange 2 which is in contact with the upper side of the battery cover and a lower radially inwardly directed flange 3 with a sharp edge, which serves the purpose of enabling rotation of electrolyte in accordance with what will be described in the following.
En tætningsindsats 4 er anbragt radialt inden for hylsteret. Indsatsen omfatter en indre blybøsning 5 med et plastlegeme 6 anbragt på ydersiden. Plastlegemet 6 er hensigtsmæssigt blevet anbragt på bøsningen 5 ved sprøjtning, idet bøsningen 5 er forsynet med ophøjede kanter 7 til at opnå bedre kontakt mellem blybøsningen og plastmaterialet.A sealing insert 4 is arranged radially inside the casing. The insert comprises an inner lead sleeve 5 with a plastic body 6 arranged on the outside. The plastic body 6 has conveniently been placed on the sleeve 5 by spraying, the sleeve 5 being provided with raised edges 7 to obtain better contact between the lead sleeve and the plastic material.
Plastlegemets 6 yderside har et omkringgående spor 8, som sammen med den modstående væg i det cylindriske hylster 1 i blygennemføringens færdigmonterede tilstand danner sæde for en tætningsring, fx O-ringen 9. Bredden af sporet 8 er hensigtsmæssigt sådan at O-ringen 9 kan bevæge sig i begrænset omfang. Det indses let at sporet 8 kan være dannet i hylsterets 9 indervæg i stedet for plastlegemet 6, idet sporets dybde dog i hvert tilfælde bør være sådan at intim berøring sikres mellem indersiden af hylsteret 151426 3 1 og ydersiden af plastlegemet 6. Når batteriet befinder sig i drift optages radielle kræfter af hylsterets 1 indervæg via tætningsindsatsen 4.The outside of the plastic body 6 has a circumferential groove 8, which together with the opposite wall in the cylindrical casing 1 in the pre-assembled condition of the lead bushing forms a seat for a sealing ring, eg the O-ring 9. The width of the groove 8 is suitably such that the O-ring 9 can move to a limited extent. It is easily understood that the groove 8 may be formed in the inner wall of the casing 9 instead of the plastic body 6, however the depth of the groove should in each case be such that intimate contact is ensured between the inside of the casing 151426 3 1 and the outside of the plastic body 6. When the battery is in operation, radial forces are absorbed by the inner wall of the casing 1 via the sealing insert 4.
Plastlegemet 6 udviser foroven en omkringgående krave 10, som omgribes af den med flange forsynede kant af en tætningskapsel 11. Den sidstnævnte udgør ikke nogen del af opfindelsen og vil derfoF ikke blive beskrevet i detaljer.The plastic body 6 has at the top a circumferential collar 10 which is gripped by the flanged edge of a sealing capsule 11. The latter does not form any part of the invention and will therefore not be described in detail.
Den polbolt, hvortil den viste blygennemføring er beregnet, er vist ved 12 og omfatter en med blykappe forsynet kobberleder 13, idet blykappen er betegnet med tallet 14. Lederen 13 er vist med en kobberindsats 16 til at formindske polboltens indre modstand.The pole bolt for which the lead lead shown is intended is shown at 12 and comprises a lead conductor 13 provided with a lead sheath, the lead sheath being denoted by the number 14. The lead conductor 13 is shown with a copper insert 16 for reducing the internal resistance of the pole bolt.
Polbolten 12 antages at være forbundet med en for flere elektrodeplader fælles polbro. Som det fremgår af tegningen er hylsterets 1 diameter meget større end polboltens 12 diameter, hvilket letter blygennemføringens montering på den udragende del af polbolten.The pole bolt 12 is assumed to be connected to a pole bridge common to several electrode plates. As can be seen from the drawing, the diameter of the casing 1 is much larger than the diameter of the pole bolt 12, which facilitates the mounting of the lead lead-through on the projecting part of the pole bolt.
Når blygennemføringen anbringes i låget af et akkumulatorbatteri, indføres hylsteret 1 i den hertil beregnede åbning, hvorigennem polbolten passerer. Tætningsindsatsen passes derpå ind i tætningsringen 9 over den udragende ende af polbolten, således at der etableres glidekontakt med indersiden af hylsteret, sådan som det fremgår af tegningen. Blybøsningen 5 svejses derefter foroven fast til blykappen 14, som tilhører polbolten 13 i overensstemmelse med det som vises ved 15, hvorved polbolten 13 bliver tætnende forbundet med tætningsindsatsen 4.When the lead lead-through is placed in the lid of an accumulator battery, the casing 1 is inserted into the opening provided for this purpose, through which the pole bolt passes. The sealing insert is then fitted into the sealing ring 9 over the projecting end of the pole bolt, so that a sliding contact is established with the inside of the casing, as can be seen from the drawing. The lead sleeve 5 is then welded at the top to the lead sheath 14, which belongs to the pole bolt 13 in accordance with that shown at 15, whereby the pole bolt 13 is sealingly connected to the sealing insert 4.
Som det fremgår af det ovenstående kan tætningsindsatsen 4 og altså også polbolten bevæge sig i aksial retning i forhold til hylsteret 1 uden at der opstår unormale spændinger i batteriets låg. Hvis således polbolten skulle ekspandere i aksial retning under batteriets drift opstår der ingen skader på batteriet som følge af at indsatsen 4 er glidelig fastgjort i polbolten ved hjælp af svejsningen 15.As can be seen from the above, the sealing insert 4 and thus also the pole bolt can move in axial direction relative to the casing 1 without abnormal stresses occurring in the battery cover. Thus, if the pole bolt were to expand in the axial direction during the operation of the battery, no damage occurs to the battery as a result of the insert 4 being slidably fixed in the pole bolt by means of the weld 15.
Eventuel elektrolyt som løber ned langs polbolten vil blive opsamlet ved kanten 3 og løber derfra ned i battericellen. Svejsningen 15 tjener dog som ekstra tætning hvis elektrolyten ikke skulle blive opfanget af kanten 3 men fortsætte med at Vandre langs polbolten 13.Any electrolyte running down the pole bolt will be collected at the edge 3 and run from there down into the battery cell. However, the weld 15 serves as an additional seal if the electrolyte should not be caught by the edge 3 but continue to travel along the pole bolt 13.

Ved udførelsesformen på fig. 3 er den knivæg-lignende dræningsoverflade eller -overfladerne erstattet med en bælglignende tætningskonstruktion 20. Tætningsindsatsen 4 omfatter også i dette tilfælde en indre blybøsning 5 med et ydre plastlegeme 6. I dette tilfælde har plastlegemet 6 imidlertid en nedre del 17 med ringfor-migt udseende med et ben 18, som strækker sig bagom blybøsningen i berøring med polboltens 13 blykappe. Den bælglignende tætningskonstruktion 20 udgør en forlængeide af dette ben 18.In the embodiment of FIG. 3, the knife wall-like drainage surface or surfaces are replaced with a bellows-like sealing structure 20. In this case, the sealing insert 4 also comprises an inner lead sleeve 5 with an outer plastic body 6. In this case, however, the plastic body 6 has a lower part 17 with an annular appearance. with a leg 18 extending behind the lead sleeve in contact with the lead jacket of the pole bolt 13. The bellows-like sealing structure 20 forms an extension of this leg 18.
Den ene ende af konstruktionen 20 er fortykket til en del 19, som ved hjælp af en svejsning er fastgjort i den nedre ende af hylsteret 1, hvorved der tilvejebringes en effektiv tætning mod elektrolytens udtrængning. Også her tjener tætningsringen 9 og svejsningen 15 som hjælpemiddel til at forhindre at der udgår elektrolyt fra battericellen.One end of the structure 20 is thickened to a part 19, which by means of a weld is fixed in the lower end of the casing 1, thereby providing an effective seal against the ejection of the electrolyte. Here, too, the sealing ring 9 and the weld 15 serve as an aid in preventing electrolyte from escaping from the battery cell.
Hvis polbolten 14 skulle bevæge sig i aksial retning vil den bælglignende konstruktion 20, som det fremgår af fig. 3, gøre det muligt for tætningsindsatsen 4 at bevæge sig mod indersiden af hylsteret 1.If the pole bolt 14 were to move in the axial direction, the bellows-like structure 20, as shown in fig. 3, enable the sealing insert 4 to move towards the inside of the casing 1.
I øvrige henseender er udførelsesformen på fig. 3 identisk med den der er vist på fig. 1.In other respects, the embodiment of FIG. 3 identical to that shown in FIG. 1.
