  • FIG. 11 is an elevational view of a gang of retainers formed from the blank of FIG. 10.
  • FIG. 12 is a side elevational view, partly in section, of the construction shown in FIG. 11.
  • FIGS. 1-5 Fuse retainers according to the embodiment of the invention shown in FIGS. 1-5 are adapted to be formed from a blank 1 cut from a flat sheet of resilient, electrically conductive material such as that described by the Copper Development Association as alloy No. 230 and commonly known as red brass. Other materials may be used, however.
  • the blank 1 may be stamped from a sheet of such material and comprises a pair of similar, but oppositely arranged blank sections 2 and 3 and an intermediate or mounting section 4.
  • the section 2 is joined to the section 4 by spaced, parallel legs 5 and the section 3 is joined to the section 4 by spaced, parallel legs 6, the legs 6 being shorter than the legs 5 and staggered with respect to the latter.
  • the blank section 2 includes a plurality of bodyforming panels 7 extending laterally a uniform distance on opposite sides of the associated connecting leg 5.
  • the opposite end of each panel 7 has a generally semicircular notch 8 terminating at one end in an edge 9 which parallels the connecting leg 5 and terminating at its other end in an oblique edge 10.
  • Each panel 7 has a substantially centrally located, rectangular aperture 11.
  • each panel 7 Extending from each panel 7 in axial alignment with the associated connecting legs 5 is an arm 12 terminating at its free end in an enlargement 13 which is slotted or bifurcated as at 14 to form a pair of parallel fingers 15.
  • the blank section 3 is shaped to conform exactly to the shape of the blank section 2, and those parts of the blank section 3 which correspond to the parts of the blank section 2 are identified by the same reference characters, followed by the suffix a.
  • the panels 7a of the blank section 3 are staggered with respect to the panels 7 of the blank section 21, but the panels 7a otherwise form a minor image of the panels 7.
  • the arms 12 may be shaped to form a loop L;
  • the end portions of the panels 7 then may be bent through 90 along the lines 16 to form wall portions 17.
  • the panels 7 also are bent through 90 along the lines 18 which extend in prolongation of the edges of the connecting legs 5, whereupon the panels 7 form a hollow body 19 (FlG. 3) having a vertically slotted front wall 20 formed-by the confronting wall portions 17, a pair of parallel side walls 21, and a rear wall 22.
  • the body 19 overlies the mounting section 4 and the adjacent edges of the body walls are spaced from the section 4 and from the overlyinglegs 5 so as to enable the front wall-forming portions 17 to move toward and away from one another.
  • Each of the arms 12 is bent into substantially oval shape (see FlG. 5) and in such manner that the fingers l5 straddle the aperturell and bear against the rear wall 22 of the associated body l9.
  • the arms 120 may be bent in a manner similar to the arms 12 and each of the panels 7a may be bent along the lines 16a and 18a in the same manner that the panels 7 were bent.
  • the blank section 3. then may be bent upwardly through 90, as indicated by the arrow in FIG. 2, along the line C-C so that the bodies 19a alternate and are in alignment with the'bodies 19. See FIGS. 3 and 4.
  • the lower edges of the walls of the bodies 19a are located at the same level as the lower edges of the bodies 19 and are spaced frommounting section 4 by the connecting legs 6.
  • the mounting section 4 has a plurality of blade terminals 23 which alternate with the connecting legs and which may be bent downwardly along the line A-A for connection with other terminals (not shown) forming part of an electrical circuit.
  • FIGS. 10-12 is quite similar to that earlier described, and corresponding parts are designated by the same reference characters.
  • the mounting section 4 has joined thereto flanges 24 and 25 which are adapted to be rolled into cylindrical terminals so as to permit the flange 24 to be crimped to a conductor (not shown) and the flange 25 to be crimped to insulation (not shown) which encircles the conductor.
  • the apparatus shown in FIGS. 10-12 is the same as the apparatus earlier deof the partitions 30 is provided with a deep notch 32 in its central portion.
  • the partitions 30 extend the full width of the block 26, but since the bottom 27 terminates short of both end walls 28, a pair of parallel rows of open top and open bottom cavities 33 is provided at the opposite sides of the block.
  • the end walls 29 and the end portions of the partitions 30 have flanges 34 which confront one another and overlie the cavities 33.
  • the wall 29 and the partitions also have vertical shoulders 34a adjacent the sides of the bottom 27.
  • the side walls 28 are vertically slotted as at 35 adjacent each partition 30 and each slot is occupied by a resilient finger 36 formed integrally with the wall 28 and having a latching pawl 37 which projects into the associated cavity 33.
  • the body 26 preferably includes integral means, such as apertured ears 38, for the accommodation of screws (not shown) by means of which the block may be mounted on any suitable support.
  • a gang of retainer bodies 19, 19a is introduced to one row of cavities 33 of the block 26 from the bottom thereof and is pushed inwardly.
  • the rear wall 22, 22a of the respective bodies will engage the pawls 37 and cam them outwardly of the associated cavity until such time as the aperture 11, 11a registers with the pawl.
  • the resilience of the fingers 36 then will move the pawls into the associated apertures, whereupon the retaining bodies will be removably supported in the block.
  • a second set of ganged bodies 19, 19a may be inserted in the other row of cavities 33 of the block 26 in the same manner so that the split front walls 20, 20a of the two sets of retaining bodies confront one another as is shown in FIG. 9.
  • the overhanging flanges 34 and the ends of the partitions 30 prevent movement of the retainer bodies through the upper ends of the cavities, the flanges 34a prevent movement of the bodies toward one another, and the pawls 37 prevent inadvertent movement of the bodies through the lower ends of the cavities.
  • each fuse 39 comprises a tubular body 40 formed of insulating material and within which is a thermally sensitive conductor (not shown).
  • a metallic end cap 41 of cylindrical configuration and to which the ends of the conductor are joined.
  • the diameter of the end caps 41 is such as to enable them to be engaged snugly by the socket formed by the arcuate edges of the front wall portions 17, 17a.
  • the oblique edges 10, 10a form a tapered throat to facilitate introduction of the fitting of the end caps into the retainers.
  • the width of each retainer body is sufficiently less than the width of its associated cavity 33 to permit the body side walls 21, 21a to be spread apart as the end caps of the fuse pass through the throats into the sockets.
  • each fuse 39 and the loop formed by the arms 12, are such that each terminal end of the end caps 41 bears against that portion 42, 42a of the respective arms 12, 120 which lies between the front and rear walls of the retaining bodies and forcibly compresses the loop so as to provide snug engagement between the loops and the end of each cap 41.
  • the ability of the fingers 15, 15a at the ends of the respective arms 12, 12a to slide enables the looped arms 12, 12a to exert a force on the fuse 40 along the longitudinal axis of the latter, thereby avoiding the imposition of a force on the fuse which would tend to eject it from the socket.
  • the terminals 23 extend below the bottom 27 of the block for connection in a circuit to be controlled by the fuses. It will be understood that the terminals 23 of the gang of fuse retainers at one side of the block 26 will be connected to a source of electrical potential, such as a battery (not shown) and the terminals 23 of the other gang of retainers will be connected to electrical devices to be protected by the fuses.
  • the mounting member-4 in each instance, thus constitutes a bus for all fuse retainers of a gang.
