Claim 1
Independent Claim
338 words
A plug comprising: a housing having a compartment defined therein; an end face through which first and second blades extend and having an opening defined therein in communication with the compartment; a fuse casing mounted in the compartment for receiving a fuse therein and having an access through which the fuse is passable, the fuse casing including a first half casing and a second half casing, the first half casing being semi-cylindrical and including a first recess which is open at a first end thereof and a depression defined in a second end thereof, a pair of protrusions being respectively formed on two lateral edges thereof which define the first recess, and spaced first and second notches being defined in one of the lateral edges thereof, the second half casing being semi-cylindrical and including a second recess which is open at a first end thereof and a hook member defined in a second end thereof for being received in the depression in the first half casing, a pair of cavities being respectively defined in two lateral edges thereof which define the second recess for receiving the protrusions of the first half casing, and spaced third and fourth notches being defined in one of the lateral edges thereof and aligning with the associated first and second notches for respectively receiving the first and second conductive pieces therein, wherein the open first and second ends of the first and second half casings together define the access of the fuse casing, and wherein the first and second recesses of the first and second half casings together define a chamber for receiving the fuse; a first wire; a second wire which is in electrical connection with the second blade; a first conductive piece mounted to the fuse casing and in electrical connection with the fuse and the first blade; a second conductive piece mounted to the fuse casing an in electrical connection with the fuse and the first wire; and a lid removably mounted to the end face to cover the opening.

A plug comprising: a housing having a compartment defined therein; an end face through which first and second blades extend and having an opening defined therein in communication with the compartment; a fuse casing mounted in the compartment for receiving a fuse therein and having an access through which the fuse is passable, the fuse casing including a first half casing and a second half casing, the first half casing being semi-cylindrical and including a first recess which is open at a first end thereof and a depression defined in a second end thereof, a pair of protrusions being respectively formed on two lateral edges thereof which define the first recess, and spaced first and second notches being defined in one of the lateral edges thereof, the second half casing being semi-cylindrical and including a second recess which is open at a first end thereof and a hook member defined in a second end thereof for being received in the depression in the first half casing, a pair of cavities being respectively defined in two lateral edges thereof which define the second recess for receiving the protrusions of the first half casing, and spaced third and fourth notches being defined in one of the lateral edges thereof and aligning with the associated first and second notches for respectively receiving the first and second conductive pieces therein, wherein the open first and second ends of the first and second half casings together define the access of the fuse casing, and wherein the first and second recesses of the first and second half casings together define a chamber for receiving the fuse; a first wire; a second wire which is in electrical connection with the second blade; a first conductive piece mounted to the fuse casing and in electrical connection with the fuse and the first blade; a second conductive piece mounted to the fuse casing an in electrical connection with the fuse and the first wire; and a lid removably mounted to the end face to cover the opening.
Claim 3
Dependent Claim
46 words
The plug as claimed in claim 1, wherein the lid includes a wedge with an inclined surface projecting downwardly from a mediate portion of a lateral edge of an underside thereof, the wedge is inserted between the fuse and the fuse casing to position the fuse.
Claim 4
Dependent Claim
86 words
The plug as claimed in claim 2, wherein: the housing includes a slot defined in each of two opposite lateral sides thereof, and the lid further includes two snap fasteners respectively fasteners formed on two ends of the underside thereof and each having a snapping end for being releasably received in the associated slot, the fuse casing and a periphery which defines the opening of the end face together defining two spaced first and second side openings therebetween through which the two snap fasteners respectively extend.
Claim 5
Dependent Claim
18 words
The plug as claimed in claim 3, wherein the first and second side openings are of different sizes.
