ABSTRACT:
A device for isolating a hazardous connection on a circuit board includes an elongated enclosure having a bore extending therethrough and a slot extending longitudinally from a first end of the enclosure. A component such as a fuse, having leads on both ends, is advanced through the bore until one of the leads, bent orthogonally to the enclosure, becomes secured in a distal end (pocket) of the slot. The length of the enclosure is determined such that when the lead is engaged in the distal end of the slot, a portion of the enclosure extends over the lead to isolate any connections made by that lead from external contact. In a preferred embodiment, a second slot is provided on the other end of the enclosure wherein a second lead may then be bent orthogonally to the device, and parallel with the first lead, to isolate both leads of the component. The protective device is advantageously transparent to allow for monitoring of the component being isolated.
