Abstract

A connector for tapping power from a flat blade miniature plug-in fuse which includes a clamp which is of a size to engage the top portion of the fuse and an electrical terminal element which is carried by the clamp so as to be selectively urged into electrical contact with a portion of a fuse blade oriented within the body of the fuse.

Claims

1. A power tap for use with flat terminal blade miniature plug-in fuses of the type having a housing which includes front and rear surfaces and an upper end and at least one opening in the upper end and which further includes a terminal blade having a portion which is accessible through the opening, the power tap comprising, a clamp means having a head portion and spaced leg portions, an opening through said head portion and intermediate said leg portions, said leg portions being engagable with the front and rear surfaces of the housing of the fuse when said clamp means is mounted thereto, a terminal element mounted within said opening in said head portion and being selectively movable axially with respect thereto, said terminal element having an elongated shank having a lower electrical contact portion and an upper end portion, and an electrical contact member extending from said upper end portion, whereby said terminal element may be selectively adjusted with respect to said opening through said head portion so that said contact portion is movable with respect to said leg portions of said clamp means so as to be selectively urged within the opening in the housing to thereby selectively contact the portion of the terminal blade which is accessible through the opening in the fuse housing.

2. The power tap of claim 1 in which each of said leg portions includes an outer end, and flange elements extending toward one another on each of said outer ends of said leg portions.

3. The power tap of claim 2 in which said clamp means is formed of an electrically non-conductive material.

4. The power tap apparatus of claim 3 in which said leg portions of said clamp means are yieldable with respect to one another.

5. The power tap of claim 3 in which said opening in said head portion of said clamp means is threaded and said shank of said terminal element is cooperatively threaded so as to be adjustable within said opening in said head portion.

6. The power tap of claim 5 in which said electrical contact is a blade element oriented generally in axial alignment with said shank of said terminal element.

7. The power tap of claim 5 in which said electrical contact is a blade element oriented transversely with respect to the axis of said shank of said terminal element.

8. The power tap of claim 5 in which said electrical contact is an electrical socket means which is oriented generally transversely with respect to the axis of said shank of said terminal element

9. The power tap of claim 5 in which said electrical contact is an electrical socket which is oriented generally parallel with respect to the elongated axis of said shank of said terminal element.

10. The power of claim 1 in which said opening in said head portion of said clamp means is threaded and said shank of said terminal element is cooperatively threaded so as to be adjustable within said opening in said head portion.

11. The power tap apparatus of claim 10 in which said leg portions of said clamp means are yieldable with respect to one another.

12. The power tap of claim 1 in which said electrical contact is a blade element oriented generally in axial alignment with said shank of said terminal element.

13. The power tap of claim 1 in which said electrical contact is a blade element oriented transversely with respect to the axis of said shank of said terminal element.

14. The power tap of claim 1 in which said electrical contact is an electrical socket means which is oriented generally transversely with respect to the axis of said shank of said terminal element.

15. The power tap of claim 1 in which said electrical contact is an electrical socket which is oriented generally parallel with respect to the elongated axis of said shank of said terminal element.

16. A power tap for use with flat terminal blade miniature plug-in fuses of the type having a housing which includes front and rear surfaces and an upper end, a flange extending outwardly adjacent the upper end and at least one opening in the upper end and which further includes a terminal blade having a portion which is accessible through the opening, the power tap comprising, a clamp means formed of an electrically insulated material having a head portion and spaced leg portions, a threaded opening through said head portion and intermediate said leg portions, each of said leg portions including an outer end, flange elements extending toward one another on each of said outer ends of said leg portions so as to be engaged with the flange adjacent the upper end of the housing when said clamp means is mounted thereto, a terminal element mounted within said opening in said head portion and being selectively movable axially with respect thereto, said terminal element having an elongated threaded shank having a lower electrical contact portion and an upper end portion, and an electrical contact extending from said upper end portion whereby said terminal element may be selectively adjusted with respect to said opening so that said contact portion is movable with respect to said leg portions of said clamp means so as to be selectively urged within the opening in the housing to thereby selectively contact the portion of the terminal blade which is accessible through the opening in the fuse housing.
