Claims
- 1. A strain relief attachment assembly for attaching an electrical line cord to a utility device, said utility device having a line cord entry aperture through a body wall thereof, said electrical line cord passing through said aperture for engagement with an electrical connector at a location within said utility device comprising:
- a line cord strain relief element having a tapered recess region and being insertable through said aperture in said body wall of said utility device, said strain relief element including a passageway through which said line cord extends and a flange which is configured to generally conform with an external surface of said body of said utility device adjacent to said aperture; and
- a line cord retention wedge having a slot that is bounded by a generally wedge-shaped wall structure comprised of opposing ramp-configured walls, that are sloped to conform with a sloped surface of said tapered recess region of said line cord strain relief element, so as to draw said line cord strain relief element into said aperture of said utility device and thereby urge said flange of said line cord strain relief element into sealing engagement with said external surface of said body of said utility device.
- 2. A strain relief attachment assembly according to claim 1, wherein said line cord contains wires each of which is terminated within said utility device by a respective terminal conductor having a size less than that of said aperture.
- 3. A strain relief attachment assembly according to claim 1, wherein said line cord is a two-wire line cord.
- 4. A strain relief attachment assembly according to claim 3, wherein said utility device comprises a telephone test set.
- 5. A strain relief attachment assembly according to claim 1, wherein said line cord strain relief element further includes a shroud having a bore sized to snugly receive said line cord, so that said shroud provides a seal around the line cord as it extends through said bore in said strain relief element and into said utility device.
- 6. A strain relief attachment assembly according to claim 1, wherein said generally wedge-shaped wall structure of said line cord retention wedge includes one or more tabs that are sized to be readily gripped to facilitate removal of said line cord retention wedge from engagement with said strain relief element.
- 7. A strain relief attachment assembly according to claim 6, wherein said generally wedge-shaped wall structure is further comprised of a top wall and a reinforcing rib, which can be gripped to assist in removal of said line cord retention wedge from said recess region of said strain relief element.
- 8. A strain relief attachment assembly for attaching a two-conductor line cord to a telephone test set, said telephone test set having a body end wall in which line cord aperture is formed, said two-conductor line cord passing through said aperture and terminating in respective connectors for engagement with terminal connectors within said telephone test set comprising:
- a line cord strain relief element, having an end portion containing a tapered recess region that is sized to conform with and be insertable through said aperture in said body wall of said test set, said strain relief element including a passageway through which said line cord extends and a flange which is configured to generally conform with an external surface of said body of said test set adjacent to said aperture, and
- a line cord retention wedge having a slot which conforms with said tapered recess region of said line cord strain relief element, said slot being bounded by opposing ramp-configured walls, that are sloped to conform with a sloped surface of said tapered recess region of said line cord strain relief element, so that when said line cord retention wedge is inserted into said test set and engages said recess region of said strain relief element, said line cord strain relief element is drawn into said aperture of said test set, bringing said flange of said line cord strain relief element into sealing engagement with said external surface of said body wall of said test set.
- 9. A strain relief attachment assembly according to claim 8, wherein each wire of said two-wire line cord is terminated within said test set by a respective electrical termination having a size less than that of said aperture.
- 10. A strain relief attachment assembly according to claim 8, wherein said line cord strain relief element further includes a shroud having a bore sized to snugly receive said line cord, so that said shroud provides a seal around the line cord as it extends through said strain relief element and into said telephone test set.
- 11. A strain relief attachment assembly according to claim 10, wherein said line cord retention wedge includes one or more tabs that are sized to be gripped for removing said line cord retention wedge from said strain relief element.
- 12. A strain relief attachment assembly according to claim 11, wherein said retention wedge further comprises a top wall and a reinforcing rib, which can be gripped to assist in removal of said line cord retention wedge from said recess region of said line cord strain relief element.
