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;

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;

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.

2. The fuse holder of claim 1 further comprising an output stud coupled to or formed on the holder base.

3. The fuse holder of claim 2 wherein the fuse holder is configured to house one or more MRBF fuses therein, with the one or more MRBF fuses being positioned on the input and output studs via an opening in each of the one or more MRBF fuses.

4. The fuse holder of claim 3 wherein the holder base further comprises an electrically conductive buss bar insert molded therein that transfers power from an input wire or buss bar to the one or more MRBF fuses, with the electrically conductive buss bar being electrically isolated from the input and output studs, such that the input and output studs are on a load side of the one or more MRBF fuses.

5. The fuse holder of claim 4 wherein the cover is constructed to enclose both the one or more MRBF fuses and the pair of connection studs.

6. The fuse holder of claim 3 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 of claim 1 wherein the fuse holder comprises a blade type fuse holder configured to house a plurality of blade type fuses therein, and wherein the holder base of the blade type fuse holder comprises a box-shaped receptacle configured to receive a printed circuit board (PCB) fuse assembly that includes a plurality of blade type fuses therein.

8. The fuse holder of claim 7 wherein the plurality of blade type fuses comprise one of ATM-mini fuses, ATC fuses, and Maxi fuses.

9. The fuse holder of claim 1 further comprising an input buss bar bolted to the input stud to provide power to the fuse holder.

10. A fuse assembly comprising:

a fuse holder including;

a holder base comprising;

a main body;

an electrically conductive insert molded in the main body; and

a receptacle secured onto or formed integrally with the main body, the receptacle partially covering the electrically conductive insert and extending upwardly from the main body; and

an input stud coupled to or formed on the holder base and electrically coupled to the electrically conductive insert; and

a printed circuit board (PCB) fuse assembly including;

a printed circuit board (PCB);

fuse terminal blocks mounted to the PCB;

fuse terminals positioned within the fuse terminal blocks and electrically connected to the PCB; and

blade-type fuses inserted in the fuse terminals and electrically connected to the PCB through the fuse terminals;

wherein the PCB fuse assembly is secured onto the receptacle to mount the PCB fuse assembly on the holder base.

11. The fuse assembly of claim 10 further comprising input and output connecting pins, with the input connecting pin electrically coupling the PCB fuse assembly to the electrically conductive insert.

12. The fuse assembly of claim 11 wherein the receptacle includes a female output connector formed on surface thereof, with the output connecting pin electrically coupling the PCB fuse assembly to the female output connector.

13. The fuse assembly of claim 10 wherein the blade type fuses comprise one of ATM-mini fuses, ATC fuses, and Maxi fuses.

14. The fuse assembly of claim 10 wherein the main body of the holder base includes a plurality of mating protrusions and a plurality of mating slots formed on side surfaces thereof, with the plurality of mating protrusions and mating slots comprising 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.

15. The fuse holder of claim 10 further comprising an input buss bar bolted to the input stud to provide power to the fuse assembly.

16. The fuse holder of claim 10 further comprising a seal positioned between the PCB and the receptacle to provide ingression protection to the blade-type fuses and the PCB.

17. A fuse holder for holding one or more marine rated battery fuses (MRBF fuses) therein, the fuse holder comprising:

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

a pair of connection studs coupled to or formed on the holder base, with the pair of connection studs constructed to provide for positioning of the one or more MRBF fuses thereon; and

a cover configured to attach to the holder base to cover the one or more MRBF fuses and the pair of connection studs;

wherein the electrically conductive buss bar of the holder base transfers power from an input wire or buss bar to the one or more MRBF fuses, with the electrically conductive buss bar being electrically isolated from the pair of connection studs, such that the pair of connection studs are on a load side of the one or more MRBF fuses.

18. The fuse holder arrangement of claim 17 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.

19. The fuse holder arrangement of claim 17 wherein the holder base is configured to electrically insulate the fuse holder from an external component to which the fuse holder is mounted.

20. The fuse holder arrangement of claim 17 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.
