Abstract
A specially constructed fuseblock and rail mounting adapter are provided for mounting a fuseblock to a channel. The fuseblock comprises a base having an elongated slot opening therethrough and, on its bottom, a pair of flanges. The adapter comprises a fuseblock mounting side and a channel mounting side. The fuseblock mounting side has a top surface having a key and a pair of locking tabs extending therefrom. The key is adapted to be received by said elongated slot when said fuseblock and adapter are generally perpendicular to each other, and then, upon 90.degree. rotation of the fuseblock relative to the adapter, lock with the elongated slot. The rotation of the fuseblock also causes each pair of locking tabs to engage one of said flanges. The channel mounting side is separately engageable with three different sized rails.

A fuseblock adapter for mounting a fuseblock on a rail comprising:
- a top and a bottom,
- said bottom having means to engage a rail,
- said top having a key means extending upwardly from said top,
- said key being adapted to pass through a slot in said fuseblock and to lock said adapter on said fuseblock when said key is turned relative to said fuseblock, said key comprising a cylindrical shaft terminating in an enlarged portion,
- further comprising at least one second means for locking the fuseblock on the adapter,
- wherein said enlarged portion is an arrow-head shaped portion having a base that is longer in length than the diameter of said shaft thereby defining a pair of mating surfaces adjacent the shaft, said mating surfaces engaging said fuseblock when said adapter is locked on said fuseblock,
- wherein said adapter is locked on said fuseblock when said key is turned at least 45 degrees,
- wherein each said second locking means is a pair of spaced locking tabs.
A fuseblock adapter for mounting a fuseblock on a rail comprising:
- a top and a bottom,
- said bottom having means to engage a rail,
- said top having a key means extending upwardly from said top,
- said key being adapted to pass through a slot in said fuseblock and to lock said adapter on said fuseblock when said key is turned relative to said fuseblock, said key comprising a cylindrical shaft terminating in an enlarged portion,
- further comprising at least one second means for locking the fuseblock on the adapter,
- wherein said enlarged portion is an arrow-head shaped portion having a base that is longer in length than the diameter of said shaft thereby defining a pair of mating surfaces adjacent the shaft, said mating surfaces engaging said fuseblock when said adapter is locked on said fuseblock,
- wherein said adapter is locked on said fuseblock when said key is turned at least 45 degrees,
- wherein said rail engaging means is separately engageable with three different sized rails, and
- wherein said rail engaging means comprises first and second flanking arms and an intermediate third arm, said first flanking arm having a pair of oppositely-facing first latching surfaces, said second flanking arm having an inwardly-facing second latching surface, and said central arm having a pair of oppositely-facing third latching surfaces, said first, second and third latching surfaces being engageable with the end of at least one of said three different sized rails.
A one piece thermoplastic fuseblock adapter for mounting a fuseblock on a rail comprising:
- a generally flat top surface,
- a first pair of tabs extending upwardly from the top surface adjacent one end thereof,
- a first second pair of tabs extending upwardly from the top surface adjacent the other end thereof,
- each pair of tabs having opposed spaced mating faces defining a gap to receive a lock means on a bottom of said fuseblock,
- a key extending upwardly from said top surface between said first and second pair of tabs, said key having a cylindrical shaft extending from said top surface and terminating in an enlarged top end portion,
- a center line passing through said first and second gaps also passing through said key shaft,
- a fortification means extending from and formed under said top surface and having two ends and a bottom,
- first and second arms extending away and down from each end of said fortification,
- a guide arm extending from the bottom of said fortification contiguous with each fortification end,
- a third arm extending downwardly from the bottom of said fortification between said first and second arms, a cantilever arm extending from said first arm to flex said first arm,
- said first arm having a pair of oppositely facing rail latching surfaces,
- said third arm having a pair of oppositely facing rail latching surfaces,
- said second arm having one rail latching surface facing said third arm,
- said rail latching surfaces and arms being sized to latch thereon three different sized rails.
A system for mounting a fuseblock on a rail comprising:
- a fuseblock adapted to engage at least one fuse, said fuseblock having a base and a least one adapter mounting opening therethrough;
- and
- at least one adapter having on the bottom thereof means for engaging the rail, a key extending from the top of the adapter, said key and adapter opening being configured to permit said key to be received by said opening, whereby when said key and adapter are rotated relative to the fuseblock said adapter and fuseblock are locked together.
