Title: Magnetic component structure

Description:
The current application claims a foreign priority to the patent application of Taiwan No. 101203731 filed on Mar. 2, 2012. 
     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention generally relates to an improved magnetic component structure; in particular, the present invention relates to an improved magnetic component structure enabling installation on one side of a drive circuit board in an LED light tube. 
     2. Description of Related Art 
     Currently well-known magnetic components (e.g., inductors, transformers or the like) are ones of the most important electronic components in the electronic product, essentially applied to convert the drive voltage in the electronic circuit and generally characterized as: the magnetic component for voltage buck in a power supply, the high voltage magnetic component for operation voltage boost in a conventional or liquid crystal display, etc. The manufacturers of electronic products may select magnetic components of appropriate specifications or types in accordance with their requirements such that the voltage transformation processes can demonstrate required stability and good operation performance. 
     However, the magnetic components commonly installed on a drive circuit board in an LED lamp tube mostly include a fixed iron core with windings wound thereon. That is also the reason why the magnetic components are usually directly soldered onto one side of the circuit board, and such magnetic components are typically the electronic components occupying the largest area on the circuit board, in particular for the configuration comprising large-sized magnetic components. With regards to the development trend for modern electronic devices featuring miniature or smaller and slimmer profiles, such large-sized magnetic components, in addition to excessive space occupation, restrict the possibility for device size reduction as well. 
     Therefore, it would be an optimal solution if the magnetic component can be installed on either side of the circuit board thereby reducing the space occupied by the magnetic component. 
     SUMMARY OF THE INVENTION 
     As such, the present invention provides an improved magnetic component structure allowing installation on either side of a drive circuit board in an LED lamp tube thereby reducing the space occupied by the combination of the magnetic component with the circuit board. 
     An improved magnetic component structure capable of achieving the aforementioned innovative objectives comprises a base and two iron cores, in which the base includes a centrally through winding axle tube and the openings at both the left and right ends of the winding axle tube individually extend out a baffle, with two sets of pin parts being symmetrically installed at the outer edge on each of the baffles, and at least an upward or downward pin extending out from the pin part. Moreover, the two iron cores are caps, in which two notches are symmetrically installed on such iron cores and two symmetrical round walls extend out toward the base. Meanwhile, between the two round walls, a core column extends out at the center of the iron core toward the opening of the winding axle tube. 
     Accordingly, the two iron cores can be clip installed between the two sets of pin parts of the base and left and right assembled onto the base such that the round walls of the two iron cores can mutually match and wrap the base, and the core column can be inserted to the centrally through part of the winding axle tube. 
     More specifically, the shape of the aforementioned core column matches the centrally through part of the winding axle tube. 
     More specifically, the pins of the aforementioned pin part are used for connection in insertion to a circuit board. 
     More specifically, the aforementioned pin part is configured with a clapboard at the outer edge of the baffle, and the notches on the two iron cores can be clip installed between the inner sides of the clapboards on the two sets of pin parts, in which the pins extend outward from the clapboard and form a certain distance from the clapboard. 
     More specifically, one of the aforementioned two iron cores is disposed on the left side of the base, and the other iron core on the right side of the base. 
     In addition, the improved magnetic component structure can be installed upright on one side having a notch of a circuit board, wherein the improved magnetic component structure comprises a base and two iron cores, in which the base includes a centrally through winding axle tube and the openings at both the left and right ends of the winding axle tube individually extend out a baffle, with two sets of pin parts being symmetrically installed at the outer edge on each of the baffles, and at least an upward or downward pin extending out from the pin part. Besides, the two iron cores are embodied as caps, in which two notches are symmetrically installed on such iron cores and two symmetrical round walls extend out toward the base, and also, between the two round walls, a core column extends out at the center of the iron core toward the opening of the winding axle tube, and the core column can be inserted to the centrally through part of the winding axle tube. 
     Therefore, the two iron cores can be clip installed between the two sets of pin parts of the base and left and right assembled to the base such that the round walls of the two iron cores can mutually match and wrap the base, and the pins of the pin part can be inserted to the junction points around the notch such that the base assembled with the two iron cores can be installed upright on one side having the notch of the circuit board. 
     More specifically, the shape of the aforementioned core column matches the centrally through part of the winding axle tube. 
     More specifically, the aforementioned pin part is configured with a clapboard at the outer edge of the baffle, and the notches on the two iron cores can be clip installed between the inner sides of the clapboards on the two sets of pin parts, in which the pins extend outward from the clapboard and form a certain distance from the clapboard. 
     More specifically, one of the aforementioned two iron cores is disposed on the left side of the base, and the other iron core on the right side of the base. 
     More specifically, the size of the aforementioned base combined with the two iron cores matches the size of the notch on the circuit board such that the improved magnetic component structure can be installed upright on one side having the notch of the circuit board.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     The aforementioned and other technical contents, aspects and effects in relation with the present invention can be clearly appreciated through the detailed descriptions concerning the preferred embodiments of the present invention in conjunction with the appended drawings. 
     Refer first to  FIGS. 1 and 2 , wherein a disassembled structural diagram and an assembled structural diagram for the improved magnetic component structure according to the present invention are respectively shown. It can be seen from the Figures that the improved magnetic component structure  1  comprises a base  11  and two iron cores  12 , in which the base  11  is a centrally through winding axle tube  111  and the openings at both the left and right ends of the winding axle tube  111  individually extend out a baffle  112 , with two sets of pin parts  113  being symmetrically installed at the outer edge on each of the baffles  112 , also in which the pin part  113  is configured with a clapboard  1131  at the outer edge of the baffle  112 , at least an upward or downward pin  1132  extends outward from the clapboard  1131 , and the pin  1132  and the clapboard  1131  are kept in a certain distance. 
     Besides, one of the two iron cores  12  is disposed on the left side of the base  11 , and the other iron core  12  on the right side of the base  11 . Moreover, the two iron cores  12  are embodied as caps, in which two notches  121  are symmetrically installed on such iron cores  12  and two symmetrical round walls  122  extend out toward the base  11 , and also, between the two round walls  122 , a core column  123  extends out at the center of the iron core  12  toward the opening of the winding axle tube  111 , and the core column  123  can be inserted to the centrally through part  1111  of the winding axle tube  111 . 
     Furthermore, since the shape of the core column  123  matches the centrally through part  1111  of the winding axle tube  111 , as shown in  FIG. 2 , the two iron cores  12  can be clip installed between the inner sides of the clapboards  1131  on the two sets of pin parts  113 , such that the round walls  122  of the two iron cores  12  can mutually match and wrap the base  11  and the core column  123  can be inserted to the centrally through part  1111  of the winding axle tube  111 . 
     In addition, because the improved magnetic component structure  1  can be installed on one side of a circuit board  2 , as shown in  FIGS. 3 and 4 , one side of the circuit board  2  needs to have a notch  21  to receive the improved magnetic component structure  1 , in which the size of the base  11  combined with the two iron cores  12  has to fit into the size of the notch  21  on the circuit board  2  such that the improved magnetic component structure  1  can be successfully set upright on the side having the notch  21  of the circuit board  2 . 
     Meanwhile, at least a pin  1132  extends outward from the clapboard  1131 , as shown in  FIGS. 3 and 4 , and a plurality of junction points  22  are also configured around the notch  21  of the circuit board  2 . As shown in the Figures, the pin  1132  of the pin part  113  is set in insertion from bottom to top onto the junction point  22  around the notch  21 , and the base  11  combined with the two iron cores  12  can be installed upright on the notch  21  of the circuit board  2  so as to reduce the space occupied by the improved magnetic component structure  1  combined with the circuit board  2 . 
     In practice, an embodiment for the improved magnetic component structure  1  combined with a drive circuit board  3  in an LED lamp tube can be shown in  FIG. 5 . Herein a copper wire  4  is wound around the winding axle tube  111  to form a coil, and the wound copper wire  4  can be pulled out and soldered onto four pin parts  113 . Therefore, when the pin  1132  of the pin part  113  is set in insertion from bottom to top to the junction point  31  of the circuit board  3  and soldered onto the junction point  31  of the circuit board  3 , electrical power can be transferred to the coil by way of the pin part  1132  and the circuit board  3  and the electro-magnetic field can be created by the round wall  122  and the core column  123 , thereby causing the improved magnetic component structure  1  to operate. 
     Besides, it should be noted that, although the pin  1132  in the present invention is set in insertion from bottom to top onto the junction point  22 ,  31  of the circuit board  2 ,  3 , in practice, the same objectives and effects illustrated in the previous descriptions can be still achieved in case of setting in insertion onto the junction point  22 ,  31  of the circuit board  2 ,  3  from the top of the circuit board  2 ,  3 . 
     Compared with prior art, the improved magnetic component structure provided by the present invention further offers the following advantages: 
     1. The present invention can be installed on either side of a drive circuit board in an LED lamp tube so the space occupied by the magnetic components combined with the circuit board can be effectively reduced thereby minimizing the size of the applied electronic device or more efficiently utilizing the space inside the electronic device. 
     By way of the aforementioned detailed descriptions for the preferred embodiments according to the present invention, it is intended to better illustrate the characters and spirit of the present invention rather than restricting the scope of the present invention to the preferred embodiments disclosed in the previous texts. Contrarily, the objective is to encompass all changes and effectively equivalent arrangements within the scope of the present invention as delineated in the following claims of the present application.
