The first bobbin piece has a first channel therein and a covering element, and a primary winding coil is wound on the first bobbin piece. The second bobbin piece includes a first secondary side plate, a second secondary side plate, a plurality of partition plates, a wall portion, and a secondary base, and a secondary winding coil is wound on the second bobbin piece. The second pin includes a wire-arranging part, an insertion part and an intermediate part, wherein the wire-arranging part is protruded from the second secondary side plate, the intermediate part is buried in the wall portion, and the insertion part is protruded from the bottom surface of the secondary base. The magnetic core assembly is partially embedded within said first channel of said first bobbin piece and said second channel of said second bobbin piece. A first terminal of the secondary winding coil is fixed on the first pin and a second terminal of the secondary winding coil is fixed on the wire-arranging part of the second pin. At least parts of the second bobbin piece are received in the covering element of the first bobbin piece, and the covering element has an insulating partition for isolating the magnetic core assembly from the primary winding coil and the secondary winding coil.
Abstract:
A striking apparatus mainly includes a base, a plastic rod body formed by way of blow molding, and a striking portion. The rod body is integrally and transversally extended to form a connection rod. A helical spring is disposed between the connection rod and the striking portion. The striking portion externally forced can rapidly restore to its original state by the restoring resilience of the helical spring.
Abstract:
A method of manufacturing a transformer is disclosed. First, a first bobbin piece is provided, wherein the first bobbin piece has a first channel therein and a primary winding section. Second, a second bobbin is provided, wherein the second bobbin piece comprises a first secondary side plate, a second secondary side plate opposed to the first secondary side plate, a plurality of partition plates between the first secondary side plate and the second secondary side plate, a wall portion between every two adjacent partition plates, and a secondary base extended from an edge of the first secondary side plate and having a first pin arranged on a bottom surface of the secondary base, wherein a plurality of secondary winding sections are defined by every two adjacent partition plates, and a second channel is defined within the wall portion. Then a second pin is inserted into the second bobbin piece to penetrate through the wall portion and the second secondary side plate and form a wire-arranging part protruded from the second secondary side plate and an insertion part protruded from the bottom surface of the secondary base. Later, a primary winding coil is wound on the primary winding section, a first terminal of a secondary winding coil is fixed on the first pin and then wound on the secondary winding sections, and a second terminal of the secondary winding coil is fixed on the wire-arranging part of the second pin. Finally, a magnetic core assembly is partially disposed within the first channel of the first bobbin piece and the second channel of the second bobbin piece.
Abstract:
A fan includes an impeller, a motor, a plurality of first engaging members and a plurality of second engaging members. The impeller includes a hub and a plurality of blades disposed around the hub. The motor includes a rotor housing coupled with the hub, and the motor is for driving the impeller to rotate. The first engaging members are disposed on an inner side of the top surface of the hub, and the second engaging members are disposed on the top surface of the housing. When the impeller and the rotor housing are assembled, the second engaging members are disposed corresponding to the first engaging members, so that parts of the first engaging members are engaged into and assembled with the second engaging members.
Abstract:
A memory controller includes an output buffer for receiving a clock signal and outputting the clock signal to an external memory; and a replica buffer for receiving the clock signal and outputting the clock signal to a counting circuit; wherein the replica buffer and the output buffer have the same delay time such that the clock signal received by the counting circuit can be synchronized with that received by the external memory, and therefore the counting circuit can accurately count to a predetermined time according to the clock signal and output an enabling signal to enable a data control signal. The present invention further provides a signal synchronizing method for the memory controller.
Abstract:
The present invention provides a device for ESD protection and voltage stabilizing in order to let chip space be put in better utilization. During different conditions (i.e. ESD current occurrences and normal operation), identical elements of the device are used both for ESD protection and for voltage stabilization. The chip size and manufacturing costs necessary for the additional voltage stabilizing capacitors are thereby saved.
