Abstract

An electrical disconnect for detachably connecting segments of a drip loop of an electrical service line of a structure, the drip loop having a structure side segment and a service line segment, the electrical disconnect having a first portion connected to the structure side segment of the drip loop, the first portion comprising at least one male electrical conductor extending therefrom and a second portion connected to the service line segment of the drip loop.

Claims

1. An electrical disconnect, comprising:

a first portion having a male electrical conductor, a supporting enclosure covering a portion of the male electrical conductor, and an insulated housing substantially covering the supporting enclosure, the male electrical conductor including a single blade, the supporting enclosure having a cylindrical protrusion from which a portion of the single blade extends and the cylindrical portion provided with a smooth peripheral surface, the insulated housing having an annular extension portion with a smooth interior surface, the annular extension extending beyond the cylindrical portion of the support enclosure; and

a second portion having a female electrical conductor, a supporting enclosure entirely covering the female electrical conductor, and an insulated housing covering the supporting enclosure, the female electrical conductor including at least two conductor plates spaced apart to receive the single blade, the supporting enclosure of the second portion having an annular collar with a smooth inner surface slidably positionable about the smooth peripheral surface of the cylindrical protrusion of the first portion to laterally support the second portion relative to the first portion when the single blade is received between the conductor plates, the annular collar of the supporting enclosure of the second portion slidably removable from about the cylindrical protrusion upon separation of the single blade from the conductor plates, the insulated housing of the second portion having an annular recess with a smooth peripheral surface for receiving the extended portion of the insulated housing of the first portion when the single blade is received between the conductor plates, the conductor plates supported in such a way that the electrical conductor plates apply a holding force to the single blade, yet the single blade slidably separates from the conductor plates when a predetermined tension force is applied to the first and second portions.

2. The electrical disconnect of claim 1, wherein the supporting enclosure of the second portion is provided with a pair of inwardly extending protrusions terminating at a position adjacent the conductor plates to limit the expansion of the conductor plates upon insertion of the single blade between the conductor plates.

3. The electrical disconnect of claim 2, wherein each of the conductor plates has a planar portion a contact portion, the contact portion extending from one end of the planar portion and looping inwardly toward an opposing conductor plate, and wherein the terminating end of the inwardly extending protrusions of the supporting enclosure are positioned adjacent an intermediate point of the planar portion of the conductor plates.

4. The electrical disconnect of claim 3, wherein each of the inwardly extending protrusions of the supporting enclosure has a planar configuration and each inwardly extending protrusion is oriented in a perpendicular relationship relative to the planar portion of the conductor plates.

5. An electrical disconnect, comprising:

a first portion having a male electrical conductor, a supporting enclosure covering a portion of the male electrical conductor, and an insulated housing substantially covering the supporting enclosure, the male electrical conductor including a single blade; and

a second portion having a female electrical conductor, a supporting enclosure entirely covering the female electrical conductor, and an insulated housing covering the supporting enclosure, the female electrical conductor including at least two conductor plates spaced apart to receive the single blade, the supporting enclosure of the second portion is provided with a pair of inwardly extending protrusions terminating at a position to limit the expansion of the two conductor plates upon insertion of the single blade between the conductor plates such that the electrical conductor plates apply a holding force to the single blade, yet the single blade slidably separates from the conductor plates when a predetermined tension force is applied to the first and second portions.

6. The electrical disconnect of claim 5, wherein each of the conductor plates has a planar portion and a contact portion, the contact portion extending from one end of the planar portion and looping inwardly toward an opposing conductor plate, and wherein the terminating end of the inwardly extending protrusions of the supporting enclosure are positioned adjacent an intermediate point of the planar portion of the conductor plates.

7. The electrical disconnect of claim 6, wherein each of the inwardly extending protrusions of the supporting enclosure has a planar configuration and each inwardly extending protrusion is oriented in a perpendicular relationship relative to the planar portion of the conductor plates.
