Abstract
An electrical resistor assembly is affixed to a blower casing of a heating, venting, and air conditioning blower motor for resisting the flow of electricity to the blower motor from an electrical circuit. The assembly includes a heat dissipater for dissipating heat generated by electrical current flowing through the circuit. A connector connects the assembly to the electrical circuit. A housing contains the dissipater and the connector. The housing includes at least one catch for fixedly attaching the assembly to the casing and includes at least one break-away element for providing access to the catch. A seal circumscribes the housing including the break-away elements for providing a leak proof mating surface between the assembly and the casing.
Claims16
An electrical resistor assembly of the type affixed to a blower casing of a heating, venting, and air conditioning blower motor for resisting the flow of electricity to the blower motor from an electrical circuit, said assembly including:
- a connector;
- a heat dissipater for dissipating heat generated by electrical current flowing through the circuit;
- a housing holding said dissipater and said connector;
- a seal for providing a leak proof mating surface between said assembly and the casing:
- said housing including at least one catch for fixedly attaching said assembly to the casing and including at least one break-away element for providing access to said catch for releasing said catch from casing.
A housing for affixing a heat dissipating electrical resistor to a blower casing of a heating, venting, and air conditioning blower motor, said housing including:
- a seal for providing a leak proof mating surface between said housing and the casing;
- opposing catches for fastening said housing to the casing;
- and
- at least one break-away element for providing access to at least one of said opposing catches for releasting opposing catches from the casing.
A method for removing an electrical resistor assembly affixed to a casing of a heating, venting, and air conditioning blower, wherein said assembly includes opposing catches for affixing said resistor to said casing, said method comprising:
- breaking a portion of said assembly;
- removing said portion from said assembly for providing access to said catches;
- flexing the casing or catches for releasing the casing from said catches;
- and
- retracting said assembly from the casing.
An electrical resistor assembly of the type affixed to a blower casing of a heating, venting, and air conditioning blower motor for resisting the flow of electricity to the blower motor from an electrical circuit, said assembly including:
- a connector;
- a heat dissipater for dissipating heat generated by electrical current flowing through the circuit;
- a housing holding said dissipater and said connector;
- a seal for providing a leak proof mating surface between said assembly and the casing and being received by a groove in said housing traversing said at least one break-away element;
- said housing including at least one catch for fixedly attaching said assembly to the casing and including at least one break-away element for providing access to said catch.
A housing for affixing a heat dissipating electrical resistor to a blower casing of a heating, venting, and air conditioning blower motor, said housing including:
- a seal for providing a leak proof mating surface between said housing and the casing and being received by a groove in said housing traversing said at least one break-away element;
- opposing catches for fastening said housing to the casing;
- and
- at least one break-away element for providing access to at least one of said opposing catches.
