Abstract

An electrical wire dispenser with built-in wire cutter and insulation stripper comprises a housing for a spool of wire, and an outlet on the housing through which the free wire end can be drawn. A groove is provided on a surface of the housing, and the wire cutter and stripper are mounted in spaced relationship along the groove to perform their respective functions on the wire when positioned within the groove.

Claims

1. A wire dispenser comprising a housing, a supply of insulated wire within the housing, means on the housing for severing a portion of the wire withdrawn from the supply, and means on the housing for stripping off the insulation from the severed wire end, said housing having a wire-receiving groove extending along one surface of the housing, said severing means and stripping means being mounted in spaced relationship along the said wire-receiving groove.

2. A wire dispenser as claimed in claim 1 wherein the supply of wire is a spool of wire, and the housing has an outlet for the wire on another of its surfaces.

3. A wire dispenser as claimed in claim 2 wherein the housing is constructed in two halves, and the outlet is formed by a projecting tab on a first half engaging a slot in the second half.

4. A wire dispenser as claimed in claim 3 wherein both housing halves are generally U-shaped.

5. A wire dispenser as claimed in claim 1 wherein the severing means comprises a plunger constructed to move transverse to the groove and form with a sharp edge on the housing the means for severing the wire.

6. A wire dispenser as claimed in claim 5 wherein the stripper comprises a bifurcated plate forming a stripping slot positioned transverse to and within the groove.

7. A wire dispenser as claimed in claim 6 wherein the groove is rounded and the housing has a recessed region located between the severing means and stripping means.

8. A wire dispenser as claimed in claim 6 wherein a backing plate supports the bifurcated plate in the groove.

9. A wire dispenser as claimed in claim 2 wherein the housing is constructed of a transparent material, and a mass of resilient material is located within the spool and engages the housing walls to restrain spool rotation.

10. A wire dispenser as claimed in claim 5 wherein the plunger and sharp edge are both formed of plastic material.

11. A wire dispenser as claimed in claim 10 wherein the plunger is rotatable.

12. A wire dispenser as claimed in claim 1 wherein the spacing between the severing means and stripping means is such as to produce a preselected length of bare wire end.

13. A wire dispenser comprising a housing, a spool of insulated electrical wire mounted for rotation within the housing, means providing a path for the wire to follow when a free end of the wire is withdrawn from the spool to a point external of the housing, means mounted on the housing along the said wire path for severing a portion of the wire lying along the path, and means mounted on the housing along the said wire path spaced from and downstream of the severing means for stripping off the insulation from the severed wire end when the free wire end is pulled along the said path.

14. A wire dispenser as claimed in claim 13 wherein the spacing between the severing means and the stripping means along the said path determines the length of insulation stripped from the wire end.
