## Background
BACKGROUND OF THE INVENTION
The subject matter described herein relates to electrical devices and, more particularly, to a sensor assembly for an electrical device.
Electrical devices generally include card assemblies utilized to operate the device. The card assembly may include multiple components such as electrical modules. The modules convey electrical currents and data signals to power and/or operate the device. Often, the currents and signals conveyed by the modules produce a substantial amount of heat. The heat May cause damage to the card assembly. For example, excessive heat may melt portions of the card assembly and/or cause electrical shorts that may permanently damage the device. Some conventional devices include temperature sensors that are configured to monitor heat produced by the modules. The operation of the device may then be controlled to limit the amount of heat produced.
However, conventional temperature sensors are not without their disadvantages. Conventional temperature sensors include leads that are coupled to the card assembly. The leads may be through-hole mounted to the card assembly. The leads may also be soldered and/or welded to the card assembly. Typically, the connection between the leads and the card assembly is permanent. Accordingly, the temperature sensor cannot be replaced without reworking the entire card assembly. In some cases, the card assembly ma have to be replaced due to a damaged temperature sensor.
A need remains for a temperature sensor capable of being removably coupled to a card assembly without reworking the card assembly.

The latch 416 is configured to receive the tab 120 (shown in FIG. 5) of the plug 104.
The jack 400 includes jack contacts (not shown) positioned within an opening (not shown) in the mating end 404 of the jack 400. The jack contacts are configured to engage the plug contacts 186 (shown in FIG. 5) of the plug 104 to electrically couple the plug 104 and the jack 400. The jack 400 is configured to electrically engage the sensor 106 through the plug 104.
FIG. 12 illustrates the card assembly 401 having a sensor assembly 452 mounted thereto in a pre-connected configuration. The sensor assembly 452 includes the jack 400, the plug 104, and the temperature sensor 106. The card assembly 401 may be a circuit board, for example, a printed circuit board. The card assembly 401 may be a mother board, daughter board, midplane circuit board, or backplane circuit board. The card assembly 401 is configured to receive a plurality of electrical components (not shown) thereon. The electrical components may generate heat throughout the card assembly. The sensor assembly 452 is mounted to the card assembly 401 to monitor an amount of heat generated by the electrical components and/or the card assembly itself.
The card assembly 401 includes a surface 454. The jack 400 is mounted to the surface 454 of the card assembly 401. The jack 400 is positioned so that the mounting surface 412 of the jack 400 rests on the surface 454 of the card assembly 401. The jack 400 is oriented, substantially perpendicular to the surface 454 of the card assembly 401. The card contacts 414 of the jack 400 engage the surface 454 of the card assembly 401. The card contacts 414 are secured to the surface 454 of the card assembly 401. The surface 454 of the card assembly 401 may include pads to which the card contacts 414 are coupled. The card contacts 414 provide an electrical connection between the jack 400 and the card assembly 401.
The sensor 106 is coupled to the plug 104. An electrical connection is provided between the sensor 106 and the plug 104. The plug 104 is shown separated from the jack 102.
FIG. 13 illustrates the card assembly 401 having the sensor assembly 452 mounted thereto in a connected configuration. The plug 104 is inserted into the jack 400. The tab 120 is engaged with the latch 416 to secure the plug 104 to the jack 400. An electrical connection is created between the plug 104 and the jack 400. The electrical connection electrically engages the sensor 106 and the card assembly 401. The sensor 106 detects properties of the card assembly 401 to monitor the health of the card assembly 401. For example, the sensor 106 may be a temperature sensor configured to monitor a temperature of the card assembly 401.
If the sensor 106 becomes damaged and/or malfunctions, the sensor 106 may be replaced without damaging and/or reworking the card assembly 401. The sensor 106 is replaceable by removing the plug 104 from the jack 400. A new sensor 106 may then be joined to the plug 104 and/or a new plug 104 having a working sensor 106 may replace the original plug 104.
