Abstract

A connection apparatus includes a housing portion comprising a back panel and side panels, the back panel and side panels partially defining a cavity having an access orifice, the side panels partially defining an entry area to the access orifice, a fuse holder assembly disposed in the cavity, and a cover disposed in the cavity between a portion of the fuse holder assembly and the entry area to the access orifice, the cover obscures a portion of the fuse holder assembly.

Claims (45)

1. A connection apparatus comprising:

a housing portion comprising a back panel and side panels, the back panel and side panels partially defining a cavity having an access orifice, the side panels partially defining an entry area to the access orifice;

a fuse holder assembly disposed in the cavity and comprising a test contact portion;

a cover disposed in the cavity between a portion of the fuse holder assembly and the entry area to the access orifice, the cover configured to obscure a portion of the fuse holder assembly, the cover comprising:

a front cover panel portion having a planar surface arranged substantially parallel to a planar surface of the back panel;

a first side cover panel portion connected to the front cover panel portion and to a first extension portion connected to the back panel, the first side cover panel portion having a planar surface arranged substantially perpendicular to the planar surface of the front cover panel portion, the first extension portion having a planar surface arranged substantially parallel to the back panel; and

a second side cover panel portion connected to the front cover panel portion and to a second extension portion connected to the back panel, the second side cover panel portion having a planar surface arranged substantially perpendicular to the planar surface of the front cover panel portion, the second extension portion having a planar surface arranged substantially parallel to the back panel; and

a probe orifice extending through the cover and arranged in alignment with the test contact portion.

2. The apparatus of claim 1 , wherein the housing portion further comprises a front panel connected to the side panels, wherein the cover is disposed between the fuse holder assembly and the front panel.

3. The apparatus of claim 1 , further comprising a switch disposed in the cavity, the switch electrically connected to the fuse holder assembly.

4. The apparatus of claim 1 , wherein the cover is connected to the back panel.

5. The apparatus of claim 1 , wherein the cover is connected to the back panel with a fastener.

6. The apparatus of claim 1 , wherein the probe orifice has a diameter between approximately 2.5 mm and 4 mm.

7. The apparatus of claim 1 , wherein the cover comprises a non-conductive material.

8. The apparatus of claim 1 , wherein the cover consists of a non-conductive material.

9. The apparatus of claim 1 , further comprising a switch electrically connected to the fuse holder assembly.

10. A switch apparatus comprising:

a housing portion comprising a back panel and side panels, the back panel and side panels partially defining a cavity and an access orifice;

a switch disposed in the cavity;

a fuse holder assembly disposed in the cavity, the fuse holder assembly electrically connected to the switch and comprising a test contact portion;

a cover disposed in the cavity between a portion of the fuse holder assembly and the access orifice, the cover configured to obscure a portion of the fuse holder assembly, the cover comprising:

a front cover panel portion having a planar surface arranged substantially parallel to a planar surface of the back panel;

a first side cover panel portion connected to the front cover panel portion and to a first extension portion connected to the back panel, the first side cover panel portion having a planar surface arranged substantially perpendicular to the planar surface of the front cover panel portion, the first extension portion having a planar surface arranged substantially parallel to the back panel; and

a second side cover panel portion connected to the front cover panel portion and to a second extension portion connected to the back panel, the second side cover panel portion having a planar surface arranged substantially perpendicular to the planar surface of the front cover panel portion, the second extension portion having a planar surface arranged substantially parallel to the back panel; and

a probe orifice extending through the cover and arranged in alignment with the test contact portion.

11. The apparatus of claim 10 , wherein the housing portion further comprises a front panel connected to the side panels, wherein the cover is disposed between the fuse holder assembly and the front panel.

12. A cover comprising:

a front cover panel portion including a non-conductive material;

a first side cover panel portion connected to the front cover panel portion and arranged substantially perpendicular to the front cover panel portion;

a second side cover panel portion connected to the front cover panel portion and arranged substantially perpendicular to the front cover panel portion;

a first extension portion connected to the first side cover panel portion and arranged substantially parallel to the front cover panel portion;

a second extension portion connected to the second side cover panel portion and arranged substantially parallel to the front cover panel portion; and

a probe orifice arranged in the front cover panel portion.

13. A system comprising:

a power source; and

a connection apparatus comprising:

a housing portion comprising a back panel and side panels, the back panel and side panels partially defining a cavity having an access orifice, the side panels partially defining an entry area to the access orifice;

a fuse holder assembly disposed in the cavity, the fuse holder assembly electrically connected to the power source and comprising a test contact portion;

a cover disposed in the cavity between a portion of the fuse holder assembly and the entry area to the access orifice, the cover configured to obscure a portion of the fuse holder assembly, the cover comprising:

a front cover panel portion having a planar surface arranged substantially parallel to a planar surface of the back panel;

a first side cover panel portion connected to the front cover panel portion and to a first extension portion connected to the back panel, the first side cover panel portion having a planar surface arranged substantially perpendicular to the planar surface of the front cover panel portion, the first extension portion having a planar surface arranged substantially parallel to the back panel; and

a second side cover panel portion connected to the front cover panel portion and to a second extension portion connected to the back panel, the second side cover panel portion having a planar surface arranged substantially perpendicular to the planar surface of the front cover panel portion, the second extension portion having a planar surface arranged substantially parallel to the back panel; and

a probe orifice extending through the cover and arranged in alignment with the test contact portion.

14. The apparatus of claim 13 , wherein the housing portion further comprises a front panel connected to the side panels, wherein the cover is disposed between the fuse holder assembly and the front panel.

15. The apparatus of claim 13 , further comprising a switch disposed in the cavity, the switch electrically connected to the fuse holder assembly and the power source.
