Abstract
Description
Die Erfindung betrifft einen Akkumulator für ein schnurloses oder mobiles Gerät, insbesondere Telefon, mit einem aus wenigstens zwei Teilen herge stellten Gehäuse aus Kunststoff (Fig. 1), das eine Mehrzahl von Zellen auf nimmt, die untereinander mit Kontaktverbindern zu einem Paket zusammengefaßt sind, das an außen an dem Gehäuse befindliche Kontakte angeschlossen ist (Fig. 2).The invention relates to an accumulator for a cordless or mobile device, in particular a telephone, with a housing made of at least two parts made of plastic ( FIG. 1), which takes up a plurality of cells, which are combined with one another with contact connectors to form a package, the contacts on the outside of the housing are connected ( Fig. 2).
Wiederaufladbare Akkumulatoren der eingangs genannten Art enthalten eine Mehrzahl von Zellen, die in einem an das Gerät angepaßten Gehäuse unterge bracht sind. Das Gehäuse besteht aus wenigstens zwei Teilen aus isolierendem Kunststoff. Bei den bekannten Akkumulatoren werden die Teile des Gehäuses durch Ultraschall miteinander verschweißt (s. Fig. 1). Derartige Gehäuse bereiten bei einer Entsorgung Schwierigkeiten, da das Gehäuse und die Akku- Zellen getrennt werden müssen. Dies ist nur durch eine Zerstörung der Ge häuse möglich, wobei dann die Gefahr besteht, daß die Zellen mitbeschädigt werden und dadurch die Entsorgung weiter erschweren.Rechargeable batteries of the type mentioned contain a plurality of cells, which are housed in a housing adapted to the device. The housing consists of at least two parts made of insulating plastic. In the known accumulators, the parts of the housing are welded to one another by ultrasound (see FIG. 1). Such housings are difficult to dispose of since the housing and the battery cells have to be separated. This is only possible by destroying the housing, where there is a risk that the cells will also be damaged and further complicate the disposal.
Der Erfindung liegt die Aufgabe zugrunde, einen Akkumulator der eingangs ge nannten Art so zu gestalten, daß sowohl die Herstellung, als auch die Ent sorgung erleichtert ist.The invention has for its object a battery of the beginning ge named type so that both the manufacture and the Ent care is facilitated.
Diese Aufgabe wird dadurch gelöst, daß die Teile des Gehäuses mittels eines Nockensystems verbunden sind (Fig. 3). Bei einer Entsorgung sind die Teile trennbar, so daß dann das Paket aus den Akku-Zellen (Fig. 2) und das Gehäuse (Fig. 4 und 5) sauber getrennt werden können, ohne daß die Gefahr besteht, daß die Zellen zerstört werden.This object is achieved in that the parts of the housing are connected by means of a cam system ( Fig. 3). When they are disposed of, the parts are separable, so that the package from the battery cells ( FIG. 2) and the housing ( FIGS. 4 and 5) can then be cleanly separated without the risk of the cells being destroyed.
Die zum Verschweißen der Gehäuse angewandten Geräte werden nicht mehr be nötigt. Diese Geräte sind sehr teuer und das Ultraschallschweißen nicht problemlos. The devices used to weld the housing are no longer used compelled. These devices are very expensive and ultrasonic welding is not no problem.
Die Anzahl der Nocken sowie ihre Positionierung hängt von der Größe und der Form des Pack's ab (Fig. 5). Das andere Teil (Fig. 4) hat die gleiche Anzahl der Nockenaufnahmen.The number of cams and their positioning depends on the size and shape of the pack ( FIG. 5). The other part ( Fig. 4) has the same number of cam receptacles.
Die Nocken und die Aufnahmen haben eine Trapezform die das Einrasten ermög licht und ein einwandfreies Verbinden der Teile garantiert.The cams and the receptacles have a trapezoidal shape that allows them to snap into place light and a perfect connection of the parts guaranteed.
Das Zusammenpressen der Teile muß unbedingt in Achse der Nocken und der Auf nahmen geschehen. Deswegen beinhaltet mindestens eine Hälfte des Gehäuses Führungsstäbe (Fig. 5), die für das Zentrieren und das axiale Verbinden der Teile sorgen. Diese Stäbe müssen höher als die Nocken sein.The pressing of the parts must be done in the axis of the cams and the recordings. For this reason, at least one half of the housing contains guide rods ( FIG. 5), which ensure that the parts are centered and axially connected. These bars must be higher than the cams.
In jeder Nockenaussparung wird eine Nockenführung angebracht, die verhindert, daß der Nocken sich bei dem Zusammenfügen der Gehäuseteile in das Gehäuse innere verbiegen könnte (Fig. 6).A cam guide is attached in each cam recess, which prevents the cam from bending inside when the housing parts are joined into the housing ( FIG. 6).
Für eine zusätzliche Sicherheit kann der Nocken des Oberteiles mit der Nockenführung des Unterteiles verklebt werden.For additional security, the cam of the upper part can be used with the Cam guide of the lower part can be glued.
