Abstract
A fuse puller includes a central handle portion and a blade fuse fixture at one end having a pair of generally colinear tines, each tine having a barb at its end with a tab like projection extending inwardly to engage the upraised shoulder of a blade type fuse. A center stem extends between the tines and has a generally concave platform surface adapted to receive the barrel of a barrel type fuse. The other end of the tool has a generally flattened hook like projection for sliding insertion between a barrel type fuse and fuse block and pivoting movement under the end of a barrel type fuse to pry out an end thereof. The fuse puller may be a one piece injection molded structure made from a polycarbonate compound.
Claims12
A tool to facilitate the insertion and removal of at least a blade-type fuse from a spring clip receptacle, the fuse having an enlarged head with a raised shoulder surrounding same, said shoulder having a generally flattened lower surface, said tool comprising a generally elongated handle portion for grasping the tool during use, and a pair of resilient, opposing tines depending generally colinearly from the handle, said tines having means to positively engage the lower surface of the shoulder on generally opposite sides of the fuse, the tines being resilient and having a beveled surface on the end of each tine for resiliently separating the tines as the beveled surface of the tines are forced against the fuse head, the tines resiliently snapping back after the beveled surface clears the shoulder thereby bringing the shoulder engaging means into contact with the lower surface of the shoulder, the tool being thereby attached to an inserted fuse for removal thereof, and a stem depending generally colinearly between the tines to engage the top of the fuse head so that the large fuse head may be captured between the tines and the stem during use of the tool.
A tool to facilitate the insertion and removal of either a blade type fuse or a barrel type fuse from its spring clip receptacle, the blade type fuse having an enlarged head with a raised shoulder surrounding the same, said shoulder having a generally flattened lower surface, said tool comprising a generally elongated handle portion for grasping the tool during use, a fuse fixture at one end, and a hook fixture at the other end of said handle portion, the fuse fixture having a pair of opposing tines and a stem extending therebetween, each tine having a barb at its end to engage the upraised shoulder of the blade type fuse and capture it against the stem, the tines being sufficiently flexible to press snap onto the head of an inserted blade type fuse and positively engage the lower surface of the shoulder.
