Abstract

A sensor attachment assembly for an electrical system includes a sensor housing at least partially enclosing a sensor, and a fastening member coupled to the sensor housing and being structured to extend from one portion of the sensor housing, around a corresponding electrical conductor of the electrical system and attach to another portion of the sensor housing, in order to removably attach the sensor to the electrical conductor.

Claims

1. A sensor attachment assembly for an electrical system, said electrical system comprising a sensor and a number of electrical conductors, said sensor attachment assembly comprising:

a sensor housing structured to at least partially enclose said sensor; and

a fastening member coupled to the sensor housing and being structured to extend from one portion of the sensor housing around a corresponding one of said electrical conductors and attach to another portion of the sensor housing, in order to removably attach said sensor to said corresponding one of said electrical conductors,

wherein said fastening member is an elongated strap;

wherein said corresponding one of said electrical conductors is a bus bar; and

wherein said elongated strap is structured to wrap around said bus bar and attach to the sensor housing,

wherein said elongated strap is adjustable among a plurality of predetermined positions with respect to the sensor housing;

wherein said elongated strap comprises a plurality of holes; and

wherein the sensor housing comprises a number of protrusions each being structured to be disposed in a corresponding one of said holes to removably secure said elongated strap in a desired one of said predetermined positions,

wherein said plurality of holes comprises two parallel rows of holes in said elongated strap; and

wherein said number of protrusions is a pair of pegs extending outwardly from the sensor housing,

wherein the sensor housing further comprises a top, a bottom disposed opposite the top, a first side, a second side disposed opposite the first side, a first end, a second end disposed opposite the first end, and a slot disposed at or about the first end;

wherein the bottom is structured to engage said bus bar; and

wherein said elongated strap is structured to extend through said slot, around said bus bar, and over the top of the sensor housing, and

wherein said pair of pegs extends outwardly from the first end of the sensor housing proximate to said slot.

2. The sensor attachment assembly of claim 1 wherein said elongated strap is made from silicone rubber.

3. A sensor attachment assembly for an electrical system, said electrical system comprising a sensor and a number of electrical conductors, said sensor attachment assembly comprising:

a sensor housing structured to at least partially enclose said sensor; and

a fastening member coupled to the sensor housing and being structured to extend from one portion of the sensor housing around a corresponding one of said electrical conductors and attach to another portion of the sensor housing, in order to removably attach said sensor to said corresponding one of said electrical conductors,

wherein said fastening member is an elongated strap;

wherein said corresponding one of said electrical conductors is a bus bar; and

wherein said elongated strap is structured to wrap around said bus bar and attach to the sensor housing,

wherein said elongated strap is adjustable among a plurality of predetermined positions with respect to the sensor housing;

wherein said elongated strap comprises a plurality of holes; and

wherein the sensor housing comprises a number of protrusions each being structured to be disposed in a corresponding one of said holes to removably secure said elongated strap in a desired one of said predetermined positions,

wherein said plurality of holes comprises two parallel rows of holes in said elongated strap; and

wherein said number of protrusions is a pair of pegs extending outwardly from the sensor housing,

wherein the sensor housing further comprises a top, a bottom disposed opposite the top, a first side, a second side disposed opposite the first side, a first end, a second end disposed opposite the first end, and a slot disposed at or about the first end;

wherein the bottom is structured to engage said bus bar; and

wherein said elongated strap is structured to extend through said slot, around said bus bar, and over the top of the sensor housing,

wherein said elongated strap includes a first end and a second end disposed opposite and distal from the first end;

wherein the first end of said elongated strap includes an enlarged lip portion; and

wherein said enlarged lip portion is structured to engage the sensor housing at or about said slot to prevent said elongated strap from undesirably detaching from the sensor housing, and

wherein said elongated strap further includes a rib disposed proximate to but spaced a predetermined distance from said enlarged lip portion; and

wherein said rib and said enlarged lip portion are structured to cooperate with the sensor housing to maintain said elongated strap in a desired position with respect to the sensor housing.

4. An electrical system comprising:
