Abstract

A fuse holder includes a holder base comprising a plurality of protrusions each having a mounting hole formed therein to provide for mounting of the holder base to an external component and one or more mating protrusions and one or more mating slots formed on each of opposing side surfaces. The fuse holder also includes an input stud coupled to or formed on the holder base and a cover configured to attach to the holder base to at least partially enclose one or more fuses positionable on the fuse holder. The one or more mating protrusions and the one or more mating slots formed on each of the opposing side surfaces of the holder base comprise dovetailed protrusions and slots of a matching profile capable of receiving such a dovetailed protrusion, so as to enable a side-by-side stacking and interlocking of fuse holders with such mating protrusions and mating slots.

Claims

1. A fuse holder comprising:

a holder base including;

a plurality of protrusions each having a mounting hole formed therein to provide for mounting of the holder base to an external component;

one or more mating protrusions and one or more mating slots formed on each of opposing side surfaces; and

an electrically conductive buss bar insert that is over molded in the holder base;

an input stud coupled to or formed on the holder base;

an output stud coupled to or formed on the holder base; and

a cover configured to attach to the holder base to at least partially enclose first and second fuses positioned on the input and output studs;

an input power buss bar positioned on the input stud such that the input stud extends through an opening in the input power buss bar, with the input power buss bar positioned on the first stud so as to be adjacent to the holder base and electrically coupled to the first fuse;

wherein the one or more mating protrusions and the one or more mating slots formed on each of the opposing side surfaces of the holder base comprise dovetailed protrusions and slots of a matching profile capable of receiving such a dovetailed protrusion, so as to enable a side-by-side stacking and interlocking of fuse holders with such mating protrusions and mating slots;

wherein the first and second fuses comprise first and second MRBF fuses, with the first and second MRBF fuses being positioned on the input and output studs via an opening in each of the first and second MRBF fuses; and

wherein the input power buss bar contacts the electrically conductive buss bar insert so as to be electrically coupled thereto, the electrically conductive buss bar insert transferring power from the input power buss bar to the second MRBF fuse.

2. The fuse holder of claim 1 wherein the cover is constructed to enclose both the first and second MRBF fuses and the pair of connection studs.

3. The fuse holder of claim 1 wherein the holder base is configured to electrically insulate the fuse holder from an external component to which the fuse holder is mounted.

4. A fuse holder for holding first and second marine rated battery fuses (MRBF fuses) therein, the fuse holder comprising:

a holder base comprising an electrically conductive buss bar insert that is molded therein;

a pair of connection studs comprising a first stud and a second stud coupled to or formed on the holder base, with the pair of connection studs constructed to provide for positioning of the first and second MRBF fuses thereon, respectively;

an input power buss bar positioned on the first stud such that the first stud extends through an opening in the input power buss bar, with the input power buss bar positioned on the first stud so as to be adjacent to the holder base and electrically coupled to the first MRBF fuse; and

a cover configured to attach to the holder base to cover the first and second MRBF fuses and the pair of connection studs;

wherein the input power buss bar contacts the electrically conductive buss bar insert of the holder base so as to be electrically coupled thereto, with the electrically conductive buss bar insert transferring power from the input power buss bar to the second MRBF fuse.

5. The fuse holder arrangement of claim 4 wherein the holder base further comprises one or more mating protrusions and one or more mating slots formed on each of opposing side surfaces of the holder base, and wherein the one or more mating protrusions and the one or more mating slots formed on each of the opposing side surfaces of the holder base comprise dovetailed protrusions and slots of a matching profile capable of receiving such a dovetailed protrusion, so as to enable a side-by-side stacking and interlocking of fuse holders with such mating protrusions and mating slots.

6. The fuse holder arrangement of claim 4 wherein the holder base is configured to electrically insulate the fuse holder from an external component to which the fuse holder is mounted.

7. The fuse holder arrangement of claim 4 wherein the holder base further comprises a plurality of protrusions each having a mounting hole formed therein to provide for mounting of the holder base to an external component.
