Infrared scanning port
View Patent ↗We disclose a method for securing an infrared transmissive polymer to integrated panels, deadfronts, or transition plates, thus providing a reinforced polymer window through which the thermographer can scan an energized unit without being directly exposed to contact with internal components or having to remove said panels, deadfronts, or transition plates. We also disclose a device for securing the polymer consisting of a retention frame with half shear retainers that keep the polymer locked in place.
1. A device for securing an infrared transmissive polymer to a panel comprising a retention frame, said retention frame surrounding a frame opening and having protrusions on the side of said retention frame that faces said panel, wherein said frame opening corresponds to an aperture in said panel and wherein said protrusions correspond to retention holes in said panel and polymer holes in said infrared transmissive polymer.
2. The device of claim 1 further comprising a cover configured to attach to said panel and conceal said infrared transmissive polymer.
3. The device of claim 2 wherein said cover is attached to said panel with a hinge.
4. The device of claim 1 wherein said protrusions are half shear retainers.
5. The device of claim 1 wherein said protrusions extend a distance of half the width of said retention frame.
6. The device of claim 1 wherein said retention frame has bolt holes for receiving a bolt for securing said retention frame to said panel.
7. The device of claim 6 wherein said infrared transmissive polymer includes bolt holes that correspond in position to said bolt holes of said retention frame.
