Abstract

A fuse holder for holding a fuse is provided. The fuse holder includes a body, a line side connector supported by the body, and a load side connector supported by the body. The fuse holder also includes a fuse carrier supported by the body. The fuse carrier is adapted for holding the fuse and the fuse carrier is adapted to be removed from the fuse holder. The fuse carrier defines a longitudinal axis thereof. The fuse carrier is separable from the body in a direction along the longitudinal axis of the fuse carrier.

First claim

1 . A fuse holder for holding a fuse, comprising:
a body; a line side connector supported by said body; a load side connector supported by said body; a fuse carrier, said fuse carrier supported by said body, said fuse carrier holding the fuse and said fuse carrier removable from said fuse holder, said fuse carrier defining a longitudinal axis, said fuse carrier being separable from said body in a direction along the longitudinal axis of said fuse carrier; a switch supported by said body, said switch including a first position providing electrical connection between said line side connector and said load side connector and including a second position providing electrical isolation between said line side connector and said load side connector; and a cam pivotably supported by said body and connected to said switch and engageable with said fuse carrier to move said switch from the first position to the second position and to release the fuse carrier from said body as the fuse carrier is separated from the body in a direction along the longitudinal axis of said fuse carrier.

2 . The fuse holder as in claim 1 , further comprising a blocking device for blocking the engagement of said switch into the first position when the fuse carrier is not located within the fuse holder.

3 . The fuse holder as in claim 1 :
wherein said switch comprises a toggle switch supported by said body, said switch being in toggled engagement in the first position providing electrical connection between said line side connector and said load side connector and said switch being in toggled engagement in the second position providing electrical isolation between said line side connector and said load side connector; and further comprising a blocking device for blocking the toggled engagement of said switch into the first position when the fuse carrier is not located within the fuse holder.

4 . The fuse holder as in claim 3 , wherein said blocking device urges said switch from toggled engagement in said first position to toggled engagement in said second position as said fuse carrier is removed from said fuse holder.

5 . The fuse holder as in claim 1 ;
wherein said switch includes a first portion that pivots from the first position providing electrical connection between said line side connector and said load side connector to the second position providing electrical isolation between said line side connector and said load side connector; and wherein said switch includes a second portion that includes a pair of switch contacts that selectably engage and disengage with a pair of body contacts fixedly secured to said body, the second portion slidably movable with respect to said body, the second portion operably connected to the first portion.

6 . The fuse holder as in claim 2 :
further comprising a first electrical contact for electrical connection with a first end of said fuse; further comprising a second electrical contact for electrical connection with a second end of said fuse, opposed to the first end of said fuse; and wherein said fuse holder and said blocking device engage the switch in the second position prior to the electrical disengagement of at least one of first end of said fuse to the first electrical contact and second end of said fuse to the second electrical contact as said fuse carrier is removed from said fuse holder.

7 . The fuse holder as in claim 3 :
wherein said blocking device has a first position for blocking the removal of the fuse carrier from said body when said switch is in toggled engagement in said first position; and wherein said blocking device has a second position for permitting the removal of the fuse carrier from said body when said switch is in toggled engagement in said second position.

8 . The fuse holder as in claim 3 :
wherein said blocking device comprises a blocking device feature; and wherein said fuse holder comprises a fuse holder feature for cooperation with the blocking device feature for blocking the removal of the fuse carrier from said body when said switch is in toggled engagement in said first position.

9 . The fuse holder as in claim 1 , wherein said fuse holder further comprises fuse electrical contacts mounted to said body, the contacts having concave engagement surfaces engage cylindrical peripheries of opposed cylindrical electrical contacts of the fuse.

10 . The fuse holder as in claim 1 :
wherein said cam defines one of a pocket and a protrusion; and wherein said fuse carrier defines the other of a pocket and a protrusion, the protrusion engaging the pocket to rotate said cam as said fuse carrier is separated from the body in a direction along the longitudinal axis of said fuse carrier.

11 . A fuse holder for holding a fuse, comprising:
a body; a line side connector supported by said body; a load side connector supported by said body; and a fuse carrier, said fuse carrier supported by said body, said fuse carrier holding the fuse and said fuse carrier removable from said fuse holder, said fuse carrier defining a longitudinal axis, said fuse carrier being separable from said body in a direction along the longitudinal axis of said fuse carrier; a switch supported by said body, said switch including a first position providing electrical connection between said line side connector and said load side connector and including a second position providing electrical isolation between said line side connector and said load side connector; a member in intimate contact with said switch and in intimate contact with said fuse carrier when said fuse carrier is full engaged in said body to move said switch from the first position to the second position as the fuse carrier is separated from the body in a direction along the longitudinal axis of said fuse carrier by merely pulling said fuse carrier from said body in a direction along the longitudinal axis of said fuse carrier.

12 . The fuse holder as in claim 11 , wherein said member is a pivoting cam.

13 . The fuse holder as in claim 11 :
wherein said switch comprises a toggle switch supported by said body, said switch being in toggled engagement in a first position providing electrical connection between said line side connector and said load side connector and said switch being in toggled engagement in a second position providing electrical isolation between said line side connector and said load side connector; and further comprising a blocking device for blocking the toggled engagement of said switch into the first position when the fuse carrier is not located within the fuse holder, said blocking device and said switch cooperating with each other to permit the toggled engagement of said switch into the first position when the fuse carrier is located within the fuse holder by merely inserting said fuse carrier into said body.

14 . The fuse holder as in claim 13 , wherein said blocking device urges said switch from toggled engagement in said first position to toggled engagement in said second position as said fuse carrier is removed from said fuse holder by merely inserting said fuse carrier into said body.

15 . The fuse holder as in claim 11 :
wherein said switch includes a first portion that pivots from the first position providing electrical connection between said line side connector and said load side connector to the second position providing electrical isolation between said line side connector and said load side connector; and wherein said switch includes a second portion that includes a pair of switch contacts that selectably engage and disengage with a pair of body contacts fixedly secured to said
