Compact rail mountable fuse holder
First Claim
1. A fuse holder that is mountable on a rail having receiving portions comprising:
- a housing made of insulative material, said housing including integral recesses which receive said receiving portions of said rail, said housing having a surface that is inclined at an acute angle with a sliding axis and has a notch at an intermediate position along the length thereof,contacts mounted on said housing for electrically engaging a fuse, anda sliding locking member that is slidably mounted on said housing along said sliding axis between a locked position in which said fuse holder is retained on said rail and a mounting position in which said fuse holder can be mounted on or removed from said rail, said locking member having a resilient, cantilevered tab that has an end that slides along said inclined surface as said locking member moves between said mounting position and said locked position, said cantilevered tab being resiliently deflected and biasing said locking member toward said locked position with a force along said sliding axis that increases as said locking member moves further away from said locked position, said locking member being maintained in said mounting position via snap-in engagement of said end of said tab with said notch on said housing, said end of said tab being maintained in said notch via a force against said notch.

Abstract
A fuse holder including an insulative housing with integral recesses for receiving portions of a rail and a sliding locking member that slides on the housing between a locked position in which the fuse holder is retained on the rail and a mounting position in which the fuse holder can be mounted on or removed from the rail, the sliding locking member being biased toward the locked position via a resilient cantilevered tab of the sliding locking member and maintainable in the mounting position via snap in engagement with a notch on the housing, the sliding locking member having side walls with bent taps which form lips resting on a recessed shelf surface of the housing.

-
a housing made of insulative material, said housing including integral recesses which receive said receiving portions of said rail, said housing having a surface that is inclined at an acute angle with a sliding axis and has a notch at an intermediate position along the length thereof, contacts mounted on said housing for electrically engaging a fuse, and a sliding locking member that is slidably mounted on said housing along said sliding axis between a locked position in which said fuse holder is retained on said rail and a mounting position in which said fuse holder can be mounted on or removed from said rail, said locking member having a resilient, cantilevered tab that has an end that slides along said inclined surface as said locking member moves between said mounting position and said locked position, said cantilevered tab being resiliently deflected and biasing said locking member toward said locked position with a force along said sliding axis that increases as said locking member moves further away from said locked position, said locking member being maintained in said mounting position via snap-in engagement of said end of said tab with said notch on said housing, said end of said tab being maintained in said notch via a force against said notch. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11)

12. A rail mounting assembly comprising:
-
a housing, said housing including integral recesses which receive receiving portions of a rial, said housing having a surface that is inclined at an acute angle with a sliding axis and has a notch at an intermediate position along the length thereof, and a sliding locking member that is slidably mounted on said housing along said sliding axis between a locked position in which said assembly is retained on said rail and a mounting position in which said assembly can be mounted on or removed from said rail, said locking member being biased toward said locked position via a resilient, cantilevered tab of said locking member and maintainable in said mounting position via snap-in engagement of an end of said tab with said notch on said housing, said end sliding along said inclined surface as said locking member moves between said mounting position and said locked position, said cantilevered tab being resiliently deflected and biasing said locking member toward said locked position with a force along said sliding axis that increases as said locking member moves further away from said locked position, said locking member being maintained in said mounting position via snap-in engagement of said end of said tab with said notch on said housing, said end of said tab being maintained in said notch via a force against said notch. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)

27. A rail mounting assembly comprising:
-
a housing, said housing including integral recesses which receive contacts for electrically engaging a fuse mounted on said housing, said housing having a cavity space and recessed shelf surfaces extending outwardly therefrom at an interior portion thereof, and a sliding locking member that is slidably mounted on said housing along a sliding axis between a locked position in which said assembly is retained on said rail and a mounting position in which said assembly can be mounted on or removed from said rail, said sliding locking member comprising a one-piece molded plastic part, said sliding locking member having a bottom wall and two side walls extending upwardly from said bottom wall, said side walls being located in said cavity space in said housing, said cavity space permitting sliding movement of said side walls parallel to said sliding axis, said side walls having bent tops which form lips, said lops resting on said recessed shelf surface of said housing, said side walls being resilient so as to permit said lips to be resiliently, inwardly deflected during assembly of said sliding locking member on said housing via movement along an assembly axis transverse to said sliding axis and to move outward over said shelf surfaces after being moved along said assembly axis beyond said shelf surfaces. - View Dependent Claims (28, 29, 30, 31)
