Abstract
Abstract The invention relates to an in-line fuseholder which comprises a unitary housing with a cover integral therewith. Two fuse clip insulation displacement contact assemblies are press-fit into the housing. Wire securing mechanisms are provided to facilitate a one-step connection with wires from the exterior. After being closed over the wires, the wire securing mechanisms hold the wires in the housing in a strain-relief fashion. The wire securing mechanisms are also integral with the housing.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
240 words
A fuseholder assembly comprising: (a) unitary housing means for housing fuse clip means and electrical contact means therein, and said unitary housing means having access means for providing access to electrical conducting reans to the interior of said unitary housing means; (b) cover means integral with said unitary housing means and constructed for closing-off access to the interior of said unitary housing means; (c) electrical contact means disposed in said unitary housing means for being connected to electrical conducting means; (d) fuse clip means disposed in said unitary housing means for holding fuse means therein, said fuse clip means being in electrical connection with said electrical contact means in a manner for establishing a conductive path through fuse means in electrical connection with said fuse clip means; and (e) separate wire securing means integral with said housing, movable from a first open position to a second closed and latched position for urging electrical conducting means into a position with respect to said electrical contact means for establishing electrical contact connection between said electrical conducting means and said electrical contact means in a strain relief manner with respect to said electrical conducting means, and for preventing access, in a secure and insulative manner, to said connection between said electrical conducting means and said electrical contact means whereby said cover means can be opened for changing fuse means without disrupting the electrical connection between said electrical contact means and electrical conducting means.
Claim 2
Dependent Claim
240 words
A fuseholder assembly comprising: (a) unitary housing means for housing fuse clip means and electrical contact means therein, and said unitary housing means having access means for providing access to electrical conducting reans to the interior of said unitary housing means; (b) cover means integral with said unitary housing means and constructed for closing-off access to the interior of said unitary housing means; (c) electrical contact means disposed in said unitary housing means for being connected to electrical conducting means; (d) fuse clip means disposed in said unitary housing means for holding fuse means therein, said fuse clip means being in electrical connection with said electrical contact means in a manner for establishing a conductive path through fuse means in electrical connection with said fuse clip means; and (e) separate wire securing means integral with said housing, movable from a first open position to a second closed and latched position for urging electrical conducting means into a position with respect to said electrical contact means for establishing electrical contact connection between said electrical conducting means and said electrical contact means in a strain relief manner with respect to said electrical conducting means, and for preventing access, in a secure and insulative manner, to said connection between said electrical conducting means and said electrical contact means whereby said cover means can be opened for changing fuse means without disrupting the electrical connection between said electrical contact means and electrical conducting means.
Claim 3
Dependent Claim
21 words
An assembly as in claim 1 wherein said unitary housing means is a one-piece molded unit made of insulative thermoplastic material.
Claim 4
Dependent Claim
29 words
An assembly as in claim 1 wherein said wire securing means comprises wire holding projections for compressively holding said electrical conducting means against said housing in strain relief fashion.
Claim 5
Dependent Claim
49 words
An assembly as in claim 1 wherein said cover means further comprises closing means for closing off substantially all access to the interior of said fuse-holder assembly when closed except for sufficient access to permit only said electrical conducting means to be passed into the interior of said assembly.
Claim 6
Dependent Claim
23 words
An assembly as in claim 1 wherein said unitary housing means, cover means and wire securing means are made of injection molded polypropylene.
Claim 7
Dependent Claim
19 words
An assembly as in claim 1 wherein said electrical contact means and fuse clip means are made of steel.
Claim 8
Dependent Claim
36 words
An assembly as in claim 1 wherein said electrical contact means and said fuse clip means are part of a single unit assembly which is press-fit in a secure manner into receiving means in said housing.
Claim 9
Dependent Claim
16 words
An assembly as in claim 7 wherein said electrical contact means is an insulation displacement contact.
Claim 10
Dependent Claim
16 words
An assembly as in claim 7 wherein said single unit assembly is made of conductive material.
Claim 11
Dependent Claim
39 words
An assembly as in claim 7 wherein said single unit assembly further comprises locking means for holding said wire securing insulating means in closed position when employed to secure a wire in strain relief manner in said fuseholder assembly.
Claim 12
Dependent Claim
36 words
An assembly as in claim 10 wherein said wire securing means is connected for being located within said unitary housing means in said second closed and latched position, and is independently operable from said cover means.
