Embodiment Construction

[0120] exist figure 1 A feedthrough according to the invention for a storage device, in particular an electrical storage device, is shown in cross section. The housing parts, in particular the cover, preferably the battery cover, bear the reference number 1 . The battery cover with the width D3 is deformed after being pulled upwards, for example, so as to form an opening with an edge. The glass or glass-ceramic material marked with reference number 2 is introduced into the opening with the edge. The thickness T of the battery cover is preferably only 0.1 mm to 0.3 mm. Raised edges with radius R, while possible with a smaller thickness of cover material, provide a suitable inset length. The caps of the capacitors may be formed substantially identically or at least very similarly. The presence of the radius contributes to the mechanical stability and reliability of the housing parts, especially in the case of thinner material thicknesses, since the formation of cracks in the...

Abstract

The invention relates to an electrical device, in particular an electrical storage device or sensor housing, preferably a battery, in particular a micro-battery or capacitor, having a feedthrough through a housing part which has the material thickness T of the housing of the device and is made of a metal, in particular iron, iron alloys, iron-nickel alloys, iron-nickel-cobalt alloys, KOVAR, steel, stainless steel, aluminum, aluminum alloys, AlSiC, magnesium, magnesium alloys, titanium or titanium alloys, wherein the housing part has at least one opening, the opening receiving a contact element, in particular a conductor, made of a conductive material in a glass or glass ceramic material. The invention is characterized in that the housing part has a flange in the region of the opening and thus forms an inner wall of the through-opening of the height H, EL which is greater than the material thickness T, the glass length EL of the glass or glass ceramic material preferably corresponding to the height H.

Description

Technical field [0001] The invention relates to an electrical device, in particular an electrical storage device, preferably a battery, in particular a microbattery and / or a capacitor, having a feed-through through a housing part made of metal, in particular is formed of iron, iron alloy, ferronickel alloy, ferronickel alloy, steel, stainless steel or high-quality steel, wherein the housing part has at least one opening, wherein the opening receives the contact element formed from the conductive material to the glass or glass ceramic in the material. [0002] In addition to the electrical device, a feed-through, in particular a feed-through through a housing, in particular a housing part of a storage device, and a housing and / or a housing for a storage device are also described. Housing parts. Background technique [0003] In the sense of the present invention, a battery is understood to be both a disposable battery which is disposed of and / or circulated after its discharg...
