Abstract
Abstract A glow element arrangement for electric cigarette lighters includes a disk-shaped semiconductor element of predetermined geometric configuration. The element has electrically conductive contacting surfaces for the supply of electrical current. Various arrangements are disclosed for protecting the semiconductor element, for supplying current to the contacting surfaces and for preventing stress from being applied to the semiconductor element.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
84 words
A glow element arrangement for electric cigarette lighters comprising: a disk-shaped semiconductor element of predetermined geometric configuration; first and second electrical contacts being electrically and mechanically secured to the element; a metallic pan surrounding said disk, said pan being electrically connected to said first contact; and a metal supporting bolt for supporting said disk and said pan, said bolt passing through a bore in the bottom of the pan and being electrically insulated therefrom, said bolt being electrically connected to said second electrical contact.
Claim 2
Dependent Claim
84 words
A glow element arrangement for electric cigarette lighters comprising: a disk-shaped semiconductor element of predetermined geometric configuration; first and second electrical contacts being electrically and mechanically secured to the element; a metallic pan surrounding said disk, said pan being electrically connected to said first contact; and a metal supporting bolt for supporting said disk and said pan, said bolt passing through a bore in the bottom of the pan and being electrically insulated therefrom, said bolt being electrically connected to said second electrical contact.
Claim 3
Dependent Claim
31 words
The arrangement of claim 1, wherein said first contact is an annular metallic ring surrounding said element and said second contact is centrally disposed on a lower side of said element.
Claim 4
Dependent Claim
29 words
The arrangement of claim 1 wherein the element includes two diametrically opposing supporting portions of semiconductor material, said first and second electrical contacts being affixed to said supporting portions.
Claim 5
Dependent Claim
26 words
The arrangement of claim 3 wherein the supporting portions have a thin metallic coating deposited thereon and said contacts are affixed to said coating by spot-welding.
Claim 6
Dependent Claim
38 words
The arrangement of claim 3 wherein the supporting portions have a thin metallic coating deposited thereon and wherein said contacts have an opening therein and are affixed to said supporting portion by applying an envelope of metallic material.
Claim 7
Dependent Claim
20 words
The arrangement of claim 3 wherein one of the contacts includes an L-shaped extension which is spot-welded to the pan.
Claim 8
Dependent Claim
26 words
The arrangement of claim 3 including a metallic tongue for electrically connecting the bolt to the element, said tongue being connected by spot-welding to said contact.
Claim 9
Dependent Claim
15 words
The arrangement of claim 3 wherein said first and second contacts include a trapezoidal portion.
Claim 10
Dependent Claim
56 words
The arrangement of claim 7 wherein said bolt has a head, the connecting tongue being disposed beneath the head, a first insulating element between one side of the pan and the tongue, a second insulating element on the other side of the pan, a retaining washer and a supporting element between the washer and supporting element.
Claim 11
Dependent Claim
22 words
The arrangement of claim 7 wherein the pan includes an opening therein to allow spot-welding of the connecting tongue to said contact.
Claim 12
Dependent Claim
36 words
The arrangement of claim 3 wherein the contacts are affixed directly to the supporting portions, said contacts having an opening therein, said contact being fastened to said semiconductor disk by a metallic layer covering said contact.
