Abstract
Abstract In-line fuse holders for two-bladed fuses are disclosed which can be fastened in series to an electrical wire by severing the wire in which the holder is to be incorporated, inserting the severed ends of the wire into the holder, and mechanically fastening the wire securely in the holder. Various embodiments are shown including holders in which the wires are connected with sliding guillotine blades, and those in which fastening is secured by crimping. Several of the embodiments include cover flaps which hold fuses inserted in the holders securely in place.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
246 words
An in-line fuse holder comprising: a body member having two holes therein capable of receiving inserted electric wires; mechanical and electrical connection means associated with said body member for fastening and making electrical contact with electric wires inserted in said holes while maintaining said wires apart from each other, said connection means comprising two movable metallic guillotine blades adapted to slide in slots provided in said body member, said slots being spaced from one another in substantially parallel relationship, said blades being positioned at right angles to the longitudinal axis of said wires and extending from the outside of said body member to said holes interior of said body member, wherein each of said guillotine blades has a first slit adapted to receive and thereby connect an electrical wire against which said first slit is forced, two blade slots extending from the outside of said body to a location within said body member and being adapted to receive the blades of a double-bladed fuse, said guillotine blades each including a second slit being adapted to receive a blade of said double-bladed fuse inserted into a respective one of said blade slots to enable electrical connection to said blades of a double-bladed fuse and which permit each of said blades to effect electrical contact with one of the wires inserted in said holes, thereby completing the electrical connection between said wires and, means associated with said body member to retain said double-bladed fuse within said blade slots.
Claim 2
Dependent Claim
246 words
An in-line fuse holder comprising: a body member having two holes therein capable of receiving inserted electric wires; mechanical and electrical connection means associated with said body member for fastening and making electrical contact with electric wires inserted in said holes while maintaining said wires apart from each other, said connection means comprising two movable metallic guillotine blades adapted to slide in slots provided in said body member, said slots being spaced from one another in substantially parallel relationship, said blades being positioned at right angles to the longitudinal axis of said wires and extending from the outside of said body member to said holes interior of said body member, wherein each of said guillotine blades has a first slit adapted to receive and thereby connect an electrical wire against which said first slit is forced, two blade slots extending from the outside of said body to a location within said body member and being adapted to receive the blades of a double-bladed fuse, said guillotine blades each including a second slit being adapted to receive a blade of said double-bladed fuse inserted into a respective one of said blade slots to enable electrical connection to said blades of a double-bladed fuse and which permit each of said blades to effect electrical contact with one of the wires inserted in said holes, thereby completing the electrical connection between said wires and, means associated with said body member to retain said double-bladed fuse within said blade slots.
Claim 3
Dependent Claim
47 words
An in-line fuse holder according to claim 1 in which said cover flap has first and second ends wherein said first end of said cover flap is integrally attached to said body member, while the other end is adapted to be temporarily connected to said body member.
Claim 4
Dependent Claim
16 words
An in-line fuse holder according to claim 1, wherein said body member is formed from plastic.
Claim 5
Dependent Claim
16 words
An electrical circuit which includes as a part thereof the in-line fuse holder of claim 1.
