Rectifier Mounting Plate

thingiverse

This is a mounting system for industrial battery chargers. For anyone attempting to rebuild an old charger or replace a damaged rectifier, there's a problem. The original diode is no longer available for most models, so an aftermarket rectifier must be installed instead. These replacement rectifiers are designed to attach directly to the sheet steel of a battery charger with plastic clips, but the issue lies in the fact that these clips require a square hole to insert into and cutting such holes can be nearly impossible. This is where this mounting plate comes in handy. This plate attaches securely to the back of the charger using four 0.25x1 screws and allows the rectifier to clip onto it using the included plastic clips. Drilling the required holes is a breeze; simply hold the template against the back of the charger and drill four 1/4 inch holes. If I were to redesign this mounting plate, I would aim for a thinner design. The clips are intended for thin steel plates, but my original design features a thickness of 0.1875 inches, which may be too substantial for optimal performance. I chose this thickness due to concerns about the plate being too fragile; however, I believe that printing it at 1/8 inch or even thinner would provide sufficient durability and allow the clips to secure more effectively. If printed as is, I recommend applying glue to the clips before final installation.
