Description

Die Erfindung betrifft eine Einrichtung zur Verhinderung der Zerstörung von elektrischen Batterien aus gasdichten Akkumulatoren.The invention relates to a device for preventing the destruction of electrical batteries gastight accumulators.

Diese Akkumulatoren werden zu mehreren in Gehäusen, die zumeist aus Kunststoff bestehen, beispielsweise in Uhrenanlagen oder Fornmeldegeräten verwendet.These accumulators are several in housings, which are mostly made of plastic, used for example in clock systems or form reporting devices.

Werden die verwendeten Akkus so stark nachgeladen, z. B. beim Ausfallen einer Regeleinrichtung, so entsteht in ihnen eine so starke Gasentwicklung, daß die Zellenwände nach außen getrieben werden. Bei weiterer Deformation der Akkuzellen können einzelne Zellen platzen, und auch das Gehäuse wird beschädigt, so daß die auslaufende Elektrolytflüssigkeit schwere Schäden in den mit Strom zu versorgenden Geräten anrichten kann.If the batteries used are recharged so strongly, e.g. B. if a control device fails, so the development of gas in them is so strong that the cell walls are driven outwards. at further deformation of the battery cells can burst individual cells, and the housing is also damaged, so that the leaking electrolyte fluid serious damage in the devices to be supplied with electricity can cause.

Gegenstand der Erfindung ist es, das Platzen der Akkumulatoren und des Gehäuses zu vermeiden und damit die Beschädigung des Gerätes durch austretende Elektrolyflüssigkeit zu verhindern.The object of the invention is to prevent the batteries and the housing from bursting and thus preventing damage to the device from escaping electrolyte fluid.

Erfindungsgemäß wird dies dadurch gelöst, daß durch das Gehäuse beeinflußbare Teile einen im Stromlauf der Batterien liegenden Leiter so umfassen, daß bei einer Ausdehnung des Gehäuses der Leiter unterbrochen wird. Hierdurch wird nicht nur erreicht, daß der Ladeoder Entladevorgang und damit die Deformation der Zellen gestoppt wird, sondern durch das Abschalten dieser Akkumulatoren wird auch eine Revision erforderlich, wobei die fehlerhaften Teile entdeckt und ausgewechselt werden.According to the invention this is achieved in that parts that can be influenced by the housing have a current flow of the Batteries encompass lying conductor so that the conductor is interrupted when the housing expands will. This not only ensures that the loading or Discharge process and thus the deformation of the cells is stopped, but by switching off These accumulators will also require an overhaul, with the faulty parts discovered and be replaced.

Gemäß einer vorteilhaften Ausgestaltung der Erfindung sind die Teile ineinander verzahnt ausgebildet und ίο tragen an diesen Stellen eine durch beide Teile verlaufende Rille, in die der Leiter eingelegt ist. Die Anordnung kann so getroffen sein, daß zwischen die Wandungen des Gehäuses und die Batterien Platten eingeschoben sind, die die ineinander verzahnten Teile tragen. Vorzugsweise ist der Leiter als Draht ausgebildet und verbindet die Pole der Batterien miteinander.According to an advantageous embodiment of the invention, the parts are designed to be interlocked and ίο have a groove running through both parts at these points, in which the conductor is inserted. the Arrangement can be made so that plates between the walls of the housing and the batteries are inserted, which carry the interlocking parts. The conductor is preferably designed as a wire and connects the poles of the batteries with each other.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt. Es zeigtAn embodiment of the invention is shown in the drawing. It shows

F i g. 1 ein Gehäuse mit Akkumulatoren im Querschnitt; F i g. 1 shows a housing with accumulators in cross section;

F i g. 2 die gleiche Anordnung in der Draufsicht.
In dem in F i g. 1 und 2 dargestellten Ausführungsbeispiel sind sechs gasdichte Akkumulatoren 1 bis 6 in einem Gehäuse 7 aus Kunststoff angeordnet und miteinander elektrisch verbunden. Die Anschlußleitungen nach außen sind mit 8 und 9 bezeichnet.F i g. 2 shows the same arrangement in plan view.
In the one shown in FIG. 1 and 2, six gas-tight accumulators 1 to 6 are arranged in a housing 7 made of plastic and electrically connected to one another. The connection lines to the outside are denoted by 8 and 9.

Zwischen die Akkus und die Wandungen 10 und 11Between the batteries and the walls 10 and 11

des Gehäuses sind Platten 12 bzw. 13 aus Kunststoff eingeschoben. An diesen ist jeweils winklig ein Teil 14 bzw. 15 ebenfalls aus elektrisch isolierendem Kunststoff befestigt. Diese Teile greifen an ihren freien Enden in der Art einer Verzahnung ineinander und tragen an dieser Stelle eine über beide Teile sich erstreckende Rille 16. Die Pole 17 und 18 sind durch einen dünnen Draht 19 verbunden, der in die Rille 16 eingelegt ist.Of the housing, plates 12 and 13 made of plastic are inserted. A part 14 is angled at each of these or 15 also attached from electrically insulating plastic. These parts engage in at their free ends of the type of interlocking and at this point wear one that extends over both parts Groove 16. The poles 17 and 18 are connected by a thin wire 19 which is inserted into the groove 16.

Bei einer normalen Ladung und Entladung der Akkumulatoren behalten diese und damit auch das Gehäuse weitgehend ihre ursprüngliche Form, so daß der Draht 19 nicht beeinflußt wird.With normal charging and discharging of the accumulators, they and thus also keep that Housing largely their original shape, so that the wire 19 is not affected.

*o Entsteht aber in den einzelnen Akkus, beispielsweise durch Überladen, eine zu große Gasentwicklung, so werden diese in Richtung der Gehäusewände 10, 11 aufgetrieben, und auch die Gehäusewände geben nach außen nach. Hierbei bewegen sich auch die Teile 14 und «5 15 mit nach außen und scheren den in der Rille 16 liegenden Draht 19 ab. Der Stromlauf der Akkus wird dadurch unterbrochen und damit der Ladevorgang, ehe eine Zelle oder das Gehäuse platzen kann und das mit Strom zu versorgende Gerät durch die auslaufende Elektrolytflüssigkeit beschädigt wird.* o But arises in the individual batteries, for example as a result of overcharging, too great a gas development, these are in the direction of the housing walls 10, 11 inflated, and the housing walls also give way to the outside. The parts 14 and 14 also move here «5 15 with outwards and shear the one in the groove 16 lying wire 19 from. This interrupts the current flow of the batteries and thus the charging process a cell or the housing can burst and the device to be supplied with power through the leaking Electrolyte fluid is damaged.
