Abstract

Electrical contact means for glass plates characterized in that a electrically insulating flat body, preferably plastic, with an internal groove and an inserted, on the groove depth tuned, corrugated metal spring band, which at one end bent over at right angles a slot in the flat body carried out and held, when placed with pressure on a contact point a glass plate, with the open side facing the groove of the glass plate, a Stromdurchleitung of the angled end with a cable connected metal spring band to the electrical conductive body of Glass plate allows.

Description

State of technology

The Current injection of electrical conductive coatings on glass plates, Whatever the application, they are used in the field of safety extra-low voltage often over one solved with Leitkleber-equipped copper tape, by soldering a Kabels its continuing Power supply has.

The However, relatively high enrichment of the adhesive with conductive particles leads no robust adhesion of the copper strip. Also goes in the course of time the necessary intimate touch the individual conductive particles with each other and at the points to be connected something is lost and weakens the load capacity with electricity. Indisputably advantageous, however easy attachment and non-destructive solvability of the contact band.

A Better adhesion can be achieved with conductive particles filled 2-component adhesives. The process of curing is however often for Industrial processes with ensprechenden quantities too time and cost consuming.

A Cable connection by soldering assumes that at least partially a baked solderable coating e.g. Silver-based on the glass plate is applied. The high Burning temperatures for the solderable conductive layer, which is usually applied by screen printing, however, are Limited to only a few companies that have such facilities.

From the various mechanical contacts is the glass holder mentioned, which is practically a clip equal to a glass plate with an electric one conductive web or an entire surface after introduction into to contact the glass holder. The glass holder must be safe from contact to the outside accomplished be. The weak point is the relatively unprotected contact point against moisture. Corrosion phenomena can not be ruled out.

Advantages of invention

The inventive contact device consists from an insulating plate with a closed groove and a in this inserted corrugated metal spring band whose wave height on the groove depth is tuned. The metal spring band, angled at one end is over a slot led to the top of the insulating plate and insofar held and can there, for example with a flat connector in connection experience its electrical connection with a cable.

By Gluing the plate of the contact device on the glass plate or Bolt what holes on both the glass plate and on the contact device requires, is a permanent contact device created. Since the groove is enclosed, arises after sticking or the mechanical fastening by screwing a protected interior, which prevents the penetration of moisture and thus corrosion phenomena.

The so solved flat contacting of the glass plate or its conductive path or area is packaging and transport friendly. By means of an isolated Flat connector, as used in many electrical devices can also come for the Layers are easily brought about the electrical feed.
