DETAILED DESCRIPTION OF THE INVENTION

(6) FIG. 1 illustrates a component 1 according to the present invention having two feedthrough openings 3.1, 3.2. The feedthrough openings can have a cylindrical shape around axis 5.1 or, respectively, axis 5.2, for example a round shape or an oval shape.

(7) Conductors 7.1, 7.2, shown as pins, are fed through feedthrough openings 3.1, 3.2 in a glass material 9.1, 9.2.

(8) The thickness of the component is BD, the component feedthrough opening thickness is BDD and the thickness of the separate reinforcement components 10.1, 10.2 is VD.

(9) As seen in FIG. 1, the component feedthrough opening thickness BDD is equal to BD plus VD.

(10) The outside dimension of glass material 9.1, 9.2 is GA. With a circular or oval glass material, this is consistent with the diameter of the glass plug.

(11) The reinforcement material outside dimensions VA, of the separate reinforcement component, which can be circular or annular, are 1.2-times the outside dimensions GA of the glass material. In other words, with circular or, respectively, round glass plugs and circular or, respectively, round reinforcement material, the diameter of the reinforcement material is at least 1.2-times the diameter of the glass material.

(12) Also shown in FIG. 1 is length EL of the glazing into the component feedthrough opening. In the illustrated component, the length EL of the glazing is consistent with the length of the component feedthrough opening or, respectively, the component feedthrough thickness BDD.

(13) It is also possible that the glazing length EL is shorter than the component thickness BD, but not vice versa.

(14) As material for base body 20 that represents primarily a housing component, such as a cover part, for example for a storage device such as a battery, a light metal having a specific weight of <5 kg/dm3 and/or a melting point in the range of 350 C. to 800 C. and/or an electric conductivity in the range of 5.Math.10.sup.6S/m to 50.Math.10.sup.6 S/m and/or a coefficient of expansion a (20 C. to 300 C.) in the range of 18.Math.10.sup.6/K to 30.Math.10.sup.6/K can be used. The light metals can be aluminum, aluminum alloys, magnesium, magnesium alloys. The material of conductor pins 7.1, 7.2 can be a metal, such as copper, Cusic, a copper alloy, ASC, silver, a silver alloy, gold or a gold alloy or also aluminum or an aluminum alloy.

(15) As a glass material for glazing 9.2, a phosphate glass can be used, with one such glass described in WO 2012/110247 whose disclosure content is included in its entirety by reference.

(16) FIG. 2 illustrates an alternative embodiment of the invention with same components as in FIG. 1 identified with the same reference numbers.

(17) The component is again identified with 1, however, in contrast to FIG. 1, it is now no longer a two-part component in the region of component feedthrough openings 3.1, 3.2, but is a single part. In other words, in the region of component feedthrough openings 3.1, 3.2, base body 20 includes thickenings 110.1, 110.2 which are obtained in that component 1, in the region of reinforcement 110.1, 110.2, is deep-drawn, resulting in the component receiving a thickness BDD in the region of the component feedthrough opening.

(18) Thickness BDD is always greater than thickness BD of the component. Due to forming by deep drawing and subsequent upsetting, the shape of reinforcement illustrated in FIG. 2 is achieved, wherein the outside diameter VA in the region of the reinforcement element is 1.2 times greater than the outside diameter of glazing GA.

(19) With a thickness BDD, the thickness of the upset reinforced region is also greater than thickness BD of the base material. The width of the upset reinforced region is identified with SBD.

(20) The treatment in the region of the reinforcement can be made visible, since the structure flow lines, in contrast to a component treated in a machining process, in the region of the upsetting treatment are bent by the forming process.

(21) An additional alternative arrangement according to the present invention is illustrated in FIG. 3.

(22) The component is again identified with 1. Identical components as in FIG. 1 are identified with the same reference numbers. However, in contrast to FIG. 1, it is now no longer a two-part component in the region of component feedthrough openings 3.1, 3.2, but is a single part. In other words, base body 20 includes, in the region of component feedthrough openings 3.1, 3.2, thickenings 210.1, 210.2 which are obtained by deep drawing component 1 in the region of reinforcement 210.1, 210.2 and subsequent folding, resulting in the component receiving a thickness BDD in the region of the component feedthrough opening. Due to folding, thickness BDD is approximately twice the thickness BD of the component in the illustrated embodiment. Due to forming by deep drawing and subsequent folding, the shape of the reinforcement illustrated in FIG. 3 is achieved, wherein outside diameter VA in the region of the reinforcement element is 1.2 times greater than the outside diameter of glazing GA.

(23) The thickness of the reinforced region with a thickness of approximately 2BD is greater than the thickness of the base material BD. Instead of the single fold, a multiple fold, for example a 3-time or 4-time fold, is also possible in order to adjust the thickness in the region of the reinforcement.

(24) The treatment in the region of the reinforcement can be made visible since the structure flow lines, in contrast to a component treated in a machining process, in the region of the upsetting treatment or, respectively, folding are bent by the forming process.

(25) The material of the component, in other words of the base body including the reinforcement region, can be a light metal as already described for the base body in FIG. 1.

(26) The second and third alternative that are previously described do not require the attachment of an additional component, namely the reinforcement ring.

(27) Glass materials that include the following components in mol-% can be used:

(28) TABLE-US-00001 P.sub.2O.sub.5 35-50 mol-%, such as 39-48 mol-% Al.sub.2O.sub.3 0-14 mol-%, such as 2-12 mol-% B.sub.2O.sub.3 2-10 mol-%, such as 4-8 mol-% Na.sub.2O 0-30 mol-%, such as 0-20 mol-% M.sub.2O 0-20 mol-%, such as 12-20 mol-%, where M can be K, Cs, or Rb PbO 0-10 mol-%, such as 0-9 mol-% Li.sub.2O 0-45 mol-%, such as 0-40 mol-%, or 17-40 mol-% BaO 0-20 mol-%, such as 5-20 mol-% Bi.sub.2O.sub.3 0-10 mol-%, such as 1-5 mol-%, or 2-5 mol-%

(29) The glass material can be composed such that it has a coefficient of expansion a in the range of 20 C. to 300 C.13.Math.10.sup.6/K that can be 13.Math.10.sup.6/K to 25.Math.10.sup.6/K.

(30) The invention provides a thin housing component, such as for a housing of a storage device, that has a very thin material thickness BDD and thus a low weight and large cell volume, as well as a hermitically sealed glazing having a glazing length EL in the region of the feedthrough opening for the conductors.

(31) In particular, it is possible to also provide sufficient compression for a hermetically sealed feedthrough due to a forming process, even in the case of a single-part component.

(32) On the one hand, the necessary mechanical strength with thin materials that are utilized in housings, for examples as lids, is increased and, on the other hand, provides the necessary pressures or respectively radial forces for the hermetically sealed glazing.

(33) While this invention has been described with respect to at least one embodiment, the present invention can be further modified within the spirit and scope of this disclosure. This application is therefore intended to cover any variations, uses, or adaptations of the invention using its general principles. Further, this application is intended to cover such departures from the present disclosure as come within known or customary practice in the art to which this invention pertains and which fall within the limits of the appended claims.
