DUPONT JUMPER STORAGE SYSTEM
Description
DUPONT JUMPER STORAGE SYSTEM This is another attempt to devise a workable method for storing and organizing Dupont jumpers, those indispensable items that, like resistors, are devilishly difficult to keep organized when not in use. This system uses pin headers as its basis because they positively hold the jumpers where placed, avoiding the avalanche of three or four dozen when trying to extract one. The system incorporates a number of different ways to mount and use the headers and they seem to work reasonably well. They check all the boxes except one - compactness. Each pin header is only able to accommodate 40 jumpers. If you have a lot of jumpers you'll need a lot of pin headers to hold them. The pin headers, either male or female type, are glued into the slots in the various slats and frames with cyanoacrylate gel. The slots are angled 30 degrees from the faces. Trimming off the protruding short pins on the headers before gluing is optional. It's not necessary but the pin header will fit deeper in the slot if the pins are snipped off. Use glue sparingly in the slot when gluing female headers as it tends to push up into some of the header pockets, making those locations unusable. It's better to use just a bit of glue at the ends and more on the outside of the pin header after it's in the slot. Most of these types are intended for wall mounting, either with screws or magnets. The sole exception is Type G, intended for bench top use. All except Type G have magnet pockets in the backside for 5 X 2 mm round magnets. The pockets are 1.5 mm deep; if used, the magnets will protrude about 0.5 mm from the back surface. The magnet pockets are 5.5 mm in diameter so the magnets must be glued in place if used. Type C is intended for longer jumpers. Jumper ends can be tucked behind the bar, preventing the flyaway Einstein look. Type G, the bench top model, has two legs that insert into sockets on the back side of the frame, simplifying the printing over a one piece frame. The five slats used with a Type G frame slip into place and should not be glued. The intent is to be able to manually remove a slat from the frame, pull or add jumpers and put it back in place. There is a model for a rectangular back plate for screw mounting where needed.
