Abstract: A fan motor braking apparatus and a method of controlling the same provide a braking protection before the fan motor revolves. The fan motor braking apparatus includes a conversion circuit, a braking enable circuit, a braking release circuit, and a fan motor startup circuit. The conversion circuit has a plurality of power switch elements electrically connected to the fan motor. The braking enable circuit is connected to the conversion circuit and the braking release circuit is connected to the braking enable circuit. The fan motor startup circuit receives an external DC voltage. The braking enable circuit generates a braking control signal to turn on the power switch elements when the braking enable circuit receives the external DC voltage, thus braking the fan motor.

Abstract: A detachable case assembly is disclosed to include a case body, which has front and rear angled slots, a partition plate, which separates the case body into a front and a rear holding space, a front cover, which covers the front half of the top side of the case body and which has locating rods for engaging into the front angled slots of the case body and a rear edge supported on the protruded bearing portions of the partition plate, and a rear cover, which covers the rear half of the top side of the case body and which has locating rods for engaging into the rear angled slots of the case body, a front flange supported on the partition plate and spaced below the rear edge of the front cover, raised contact portions maintained in close contact with the rear edge of the front cover.

Abstract: A screw-free fan bracket mounting structure includes a base frame mounted inside the case of a computer and a fan bracket fastened to the base frame for holding a cooling fan, the fan bracket having a top protruding block, a retaining block and a bottom hook, the base frame having an upper coupling hole, a retaining hole and a lower coupling hole for receiving the top protruding block, retaining block and bottom hook of the fan bracket respectively. The distance between the retaining block and bottom hook of the fan bracket is slightly greater than the distance between the retaining hole and lower coupling hole of the base frame so that the fan bracket is slightly compressed to produce an amount of plastic deformation and secured firmly to the base frame with an elastic force during installation.

Abstract: A bus-line protector preventing the bus-lines within a computer casing from moving around and being damaged by metal components is disclosed. The bus-line protector has a base plate and at least one wing plate, wherein the base plate has at least one notch and at least one fold line. The wing plate is extended from the fold line of the base plate and comprises at least one insert extended from a periphery of the wing plate. After placing the bus-lines on the top surface of the base plate, the wing plate is inclined inwardly at the fold line and covers the base plate. Then, the insert comprising a T-shaped protrusion is securely engaged into the notch of the base plate. As a result, the bus-lines are fixed in location and are thus protected by the bus-line protector of the present invention.
