Definitions

  • a blade-type fuse 3 comprises sheet-like blades 3b and 3b serving as male terminals and connected together by a fuse wire (not shown), and an electrically insulative resin covering the upper portions of the blades 3b and 3b.
  • the upper end portion of the resin defines a head portion 3a whose opposite sides project away from each other.
  • the blade-type fuse 3 is adapted to fit in a female terminal provided within a fuse box (not shown).
  • the female terminal holds the blades 3b and 3b by a strong resilient force to positively keep the contact between them. Consequently, it is not easy to pull the blade-type fuse 3 out of the female terminal. For this reason, a fuse puller 4, as shown in Fig. 8, is used.
  • FIG. 7 In addition to the blade-type fuse as shown in Fig. 7, another blade-type fuse of a smaller size, as shown in Fig. 3, has recently been used. Such a compact-size blade-type fuse has no enlarged head portion, and therefore cannot be pulled out of the female terminal with the conventional fuse puller, and difficulty is encountered in pulling such from a terminal fuse.
  • a fuse puller according to the preamble of claim 1 is known from US-A-4 475 283.
  • This known fuse puller device comprises a pair of spaced confronting body portions having fuse-gripping jaw sections, each formed by a wall terminating in horizontally inwardly facing lip-forming projection adapted to underlye the overhung portion of a fuse housing head portion.
  • Fig. 1 shows the appearance of the fuse puller 1 provided according to the present invention.
  • the fuse puller 1 includes a hollow body 1a of a rectangular parallelepiped shape and made of a flexible material such as a resin.
  • the hollow body 1a has a square cross-section and has opposite open ends.
  • One open end 1b of the rectangular parallelepiped body 1a serves as a fuse insertion opening.
  • the longitudinal dimension W′ of the fuse insertion opening 1b is slightly greater than the longitudinal dimension W of the head portion of the fuse, and the transverse dimension H′ of the fuse insertion opening 1b is generally equal to or slightly greater than the transverse dimension H of the head portion of the fuse.
  • the body 1a has projections 1c formed on the inner surface thereof adjacent to the insertion opening 1b, the projections 1c being adapted to be received respectively in the grooves 2b formed in the compact fuse 2.
  • Figs. 2(a) to 2(c) are cross-sectional views, of the fuse puller 1 of Fig. 1.
  • the fuse puller 1 can be deformed as indicated in dots-and-dash line in Fig. 2(a) due to its own flexible nature.
  • the number of the projections 1c is equal to the number of the grooves 2b, that is to say, four, the number of the projections 1c may be less than the number of the groove 2b if there is no problem from the standpoint of the strength.
  • the provision of at least one pair of opposed projections 1c or at least one projection 1c may be sufficient.
  • the open end 1d of the fuse puller 1 of the present invention opposite to the insertion opening 1b is also open, as shown in Fig. 6.
  • the fuse puller 1 is inclined as shown in Fig. 6(b) after the compact fuse 2 is pulled out of the female terminal as shown in Fig. 6(a)
  • the compact fuse 2 is discharged from the open end 1d by itself.
  • the fuse puller of a simple construction for pulling the compact fuse can be provided, and the pulling of the fuse out of the female terminal, which has conventionally been carried out with the fingers, etc., with much difficulty, can be easily done.
  • the fuse puller of the present invention is of such a construction that it can be easily molded of a resin, for example, by injection molding.
