International Classification:

H01R 13/64

US Classification:

439248

Abstract:

A spring-loaded assembly for coupling a connector to a computer component includes an assembly housing operable to receive a portion of a screw used to couple the connector to a chassis of an information handling system. The assembly further includes a sliding block disposed in the assembly housing and operably engaged with the screw. The sliding block is operable to move the connector between a first position and a second position. The assembly further includes a spring placed between the sliding block and at least one wall of the assembly housing. The spring operably provides an axial force to bias the connector to a first position, whereby coupling the connector to the computer component causes the connector to move to a connected position intermediate the first and second position.

Abstract:

A battery heater uses the internal resistance of the battery as the battery heating element. In one embodiment, a DC battery charger and a programmable battery load, is used in a closed loop temperature control system. In another embodiment, a DC battery charger and a resistor or small auxiliary battery heater, is used in a closed loop temperature control system. The programmable load or the small auxiliary battery heater, is enabled during full charge, low temperature conditions. The resistor or small auxiliary heater serves to both heat the battery and draw down the battery charge. In yet another embodiment, an AC heater power supply and a DC battery charger, is coupled to the battery in a closed loop temperature control system.
