Description

Pallet hanger structure of flyback transformer case

The present invention allows the flyback transformer to be mounted on a pallet in the resin injection process such as epoxy during the manufacture of flyback transformer, which is a high voltage generator that supplies high voltage to CRT tubes such as televisions. Pallet hanger structure of the flyback transformer case, and in particular the flyback transformer case of the flyback transformer to facilitate the manufacturing process of injecting and curing the resin liquid into the flyback transformer of various specifications in one pallet Pallet hanger structure.

In general, the high-voltage generating flyback transformer used to supply high-voltage current to the cathode ray tube (CRT) of an electronic product equipped with an image output device such as a TV monitor generates a high-voltage current so that insulation, Durability is required. To meet this need, an epoxy resin, an insulating material, is filled in the case of a flyback transformer.

1 is a view schematically showing a pallet hanger structure of a typical flyback transformer case for resin filling. As shown in FIG. 1, a hole 22 is formed in the case 20 in which the low pressure bobbin 10 is assembled. In the related art, a plurality of fixing rods that can be inserted into the holes 22 are installed on a pallet to fix the case 20.

2 is a view showing a conventional pallet for fixing the case of FIG. The pallet of FIG. 2 has a body 30. The body 30 has a rectangular parallelepiped shape as a whole. At the upper edge of the body 30, a mounting anchor bolt 32 is installed. The anchor bolts 32 are respectively installed at the four corners of the upper body 30. The anchor bolt 32 is coupled to a nut 34 for height adjustment.

The case fixture 40 is installed at the upper end of the inner surface of the body 30. The case fixture 40 is configured to include a vertical member 42, a horizontal member 44 and the fixing rod 46. The fixing rod 46 is inserted into the hole 22 of the case 20 described in FIG. 1 to support the case. These fixing rods 46 are installed a plurality of at regular intervals along the inner both sides of the body 30.

In the conventional pallet as shown in FIG. 2, only one type of case 20 of a predetermined standard can be fixed, and the fixing rod 46 of the fixed rod 46 is formed more than the hole 22 formed in the case 20 of FIG. Even if the diameter is only small, there is a disadvantage that the case 20 is not rotated to accurately inject the resin. Accordingly, conventionally, several pallets were required according to the specifications of the case.

An object of the present invention is to provide a pallet hanger structure of a flyback transformer case of a small size for applying to a pallet improved to mount a flyback transformer case of several specifications on one pallet.

An object of the present invention is to allow the flyback transformer case of different sizes to be selectively mounted on a pallet in which a plurality of protrusions having a predetermined polygonal cross-sectional shape are installed at predetermined intervals. A flyback transformer case for allowing epoxy to be filled in the pallet hanger structure, wherein the flyback transformer case includes a polygonal cross-sectional coupling groove formed on one side of an outer surface of the flyback transformer case and into which one projection can be inserted. Achievable by the pallet hanger structure of the flyback transformer case characterized by the above-mentioned.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

3 is a plan view showing an example of a protrusion arrangement for applying the present invention, FIG. 4 is a front view of the bending member of FIG. 3, and FIG. 5 is a right side view of the bending member of FIG. 3 to 5 illustrate a bending member 110 that is bent in a predetermined shape as shown in FIG. A plurality of holes 112 are formed in a portion disposed horizontally with the lower end of the bending member 110. These holes 112 are intended to be able to fix the bending member 110 in the required position.

As shown in the bending member 110, a plurality of protrusions 114 are formed at predetermined angular intervals. This protrusion 114 is to be mounted to the case according to the present invention described later, of course, can be modified in various forms. Only the protrusions 114 need be continuously arranged at predetermined intervals.

That is, a case having a small size may be mounted with only one protrusion 114, and a case having a large size may be mounted over two protrusions 114 disposed adjacent to each other, and thus, cases having various sizes may be mounted. The pallet hook structure of the case according to the present invention for mounting on a pallet having the arrangement of the protrusions 114 will be described in detail with reference to FIGS. 6 and 7.

Figure 6 is a perspective view of the case showing an example of the pallet hook structure of the flyback transformer case according to the present invention. The flyback transformer case 120 is shown in FIG. In the case 120, an empty space 122 for coupling a high pressure bobbin, a low pressure bobbin, etc. is formed, and an outer circumferential surface of one side is formed with a coupling groove 124 having a rectangular cross section to protrude outward. The coupling groove 124 is a portion that is coupled to one of the protrusions 114 described in FIGS. That is, by coupling the coupling grooves 124 of each case 120 to the protrusions 114 of FIGS. 3 to 5, a plurality of cases 120 may be mounted on the pallet. This pallet hook structure is applied to a case 120 having a small size.

Of course, in the case of a large standard, the pallet hanger structure should be configured in a different form, which will be described with reference to FIG.

7 is a perspective view of a case showing a pallet hook structure applied to a case of a large size. 7 illustrates a case 130 having an internal space 132 of a predetermined size for accommodating a bobbin bobbin, a low pressure bobbin, and the like. The outer surface of the case 130 is provided with a pair of coupling grooves 134. The pair of coupling grooves 134 are provided to face each other at predetermined intervals, and are arranged in the vertical direction. The coupling groove 134 has a U-shaped cross-section and is respectively coupled to two protrusions 114 arranged next to each other in FIGS. 3 to 6. The spacing between the two coupling grooves 134 may be formed in accordance with the spacing of the projections.

As can be seen from the above description, when the pallet hanger structure of the flyback transformer case according to the present invention is used, the pallet can be used in common with a case of a large size, and the mounting accuracy is solid, so that the epoxy can be injected accurately. Can achieve the effect.
