Definitions

• the present invention relates to a galvanic cell and a contact element for their contacting.
• the present invention has the object to contribute to the improvement of this situation and to provide an effective solution for contacting the arrester of galvanic cells.
• This object is achieved by a galvanic cell or by a contact element for contacting galvanic cells with features according to one of the independent claims.
• Advantage- Developments of the invention form the subject of dependent claims.
• a galvanic cell according to the invention has at least two arresters for connecting the cell to an energy source, an energy consumer or to other galvanic cells when constructing a cell block, wherein the connection of this cell is effected by means of contact elements.
• at least one of the arresters has, at least in places, a surface structure which, in the case of a non-positive connection of the arrester with a contact element, increases the pressure exerted on the arrester and contact element.
• a galvanic cell in the sense of the present invention is any type of device for the electrical storage of energy.
• the term thus includes in particular electrochemical cells of the primary or secondary type, but also other forms of energy storage such as capacitors.
• a contact element is understood to be an object with the aid of which the connection of a galvanic cell to an energy consumer, to an energy source or to other galvanic cells for constructing a cell block can take place.
• Contact elements in the narrower sense therefore always have - at least also - electrically conductive materials, via which a current flow between a trap of a cell and a device connected thereto can take place.
• contact elements in the broader sense also include devices whose material can be at least partially electrically insulating.
• contact elements in a broader sense With the help of such contact elements in a broader sense, the specific mungshunte connection of a cell to said devices supported, because for a proper connection of a cell in addition to the creation of electrically good conductive connections in some cases just their local ligation, so effective insulation must be guaranteed.
• a surface structure in the sense of the present invention means any surface property which is suitable for increasing the pressure which this article and the carrier of the surface structure exert on one another in the case of a force-locking connection of an article to a carrier of this surface structure.
• Figure 1 shows an illustration of a typical galvanic cell
• Figure 2 shows a galvanic cell according to the invention according to a preferred embodiment of the invention
• FIG. 3 shows a detailed representation of the cell according to the exemplary embodiment shown in FIG. 2;
• FIG. 4 shows an illustration of a cell block comprising two galvanic cells electrically connected in series via metallic contact elements according to a preferred embodiment of the invention
• Figure 5 shows an exploded view of the cell block shown in Figure 4.
• FIG. 6 shows a section and an associated detail enlargement of the cell block shown in FIG.
• a typical galvanic cell 101 has a package 105 and at least two outgoing conductors 102, 103, wherein openings or recesses 104 can be provided in the arresters, which assists in fixing this cell during installation.
• FIG. 2 shows a corresponding galvanic cell 201 with packaging 205 and arresters 202, 203, wherein the arresters of this cell in the entire region outside the packaging have a corresponding surface structure, preferably knurling, through which, in the case of a frictional connection a surge arrester with a contact element, the pressure between the arrester and the contact element is increased.
• Such an increase in pressure can be achieved by knurling, embossing, milling or by similar surface treatments of the arrester surface. It leads to the fact that the effective bearing surfaces are reduced during contacting. For a given force, this leads to an increase of the contact pressure and thus to an improvement in the contacting.
• the raised areas of the surface structure are better adapted to the respective joining partner and can be partially plastically deformed with the appropriate choice of material due to the higher surface pressure.
• a suitable design of the surface structure and with a suitable choice of plastic materials they compensate for gaps caused by manufacturing tolerances. In the most favorable case, the use of plastically deformable materials can even lead to a subsequent enlargement of the contact-effective surface due to the plastic deformation.
• contact pressure initially causes a plastic deformation, which may result in an increase in the effective area contact, thus reducing the contact pressure, but in the result an improvement in the electrical contact.
• the pressure increase according to the invention can therefore also be a temporary increase in pressure.
• plastically deformable material is such that it opposes elastic restoring forces at least in phases to its deformation.
• Such materials thus do not behave purely plastically, such as, for example, a plasticine, but behave at least partially elastically, sometimes even until an elastic limit is reached, but finally at least partially completely or partially compensate for the forces causing the deformation yield permanent deformation.
• Knurls are produced by means of a method also known as knurling surface structures mostly metallic body, which often have grooves and which make the surfaces of the affected mostly metallic body more grip and thus prevent slipping.
• the increased grip is based on an increase in the local contact pressure with the same force by reducing the effective area.
• the knurling can take various forms and be introduced for example by milling or embossing.
• FIG. 3 shows a detailed view of the knurled arrester of the cell shown in FIG. 2.
