Description

Resin Fill Pallet for Flyback Transformer

[Technical Field]

The present invention relates to a pallet for fixing a flyback transformer in a resin injection process such as epoxy when manufacturing a flyback transformer, which is a high voltage generator supplying a high voltage to a CRT tube such as a television. In particular, the present invention relates to a resin-filled pallet of a flyback transformer for supporting and fixing a flyback transformer so as to easily perform a manufacturing process of injecting and curing a resin solution into a flyback transformer of various specifications.

[Prior art]

In general, high-voltage generating flyback transformers used to supply high-voltage currents to cathode ray tubes (CRTs) of electronic products equipped with image output devices such as TV monitors generate high-voltage currents. Is required. To meet this need, an epoxy resin, an insulating material, is filled in the mold case of the flyback transforum.

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

2 is a view showing a conventional pallet for fixing the mold case. 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 mold case fixture 40 is installed at the upper end of the inner surface of the body 30. The mold case fixture 40 is configured to include a vertical member 42, a horizontal member 44 and a fixing rod 46. The fixing rod 46 is inserted into the hole 22 of the mold case 20 described in FIG. 1 to support the mold 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 mold case 20 of a certain size can be fixed, and the fixing rod 46 is formed from the hole 22 formed in the mold case 20 of FIG. Even if the diameter of the) is slightly small, there is a disadvantage that the mold case 20 is not rotated to accurately inject the resin. Accordingly, conventionally, several pallets were required according to the specifications of the mold case.

The purpose of the present invention is to enable the resin filling operation of flyback transformers of various specifications, and also the resin of the flyback transformer to perform the accurate resin filling operation by accurately fixing the mold case of the flyback transformer. To provide a filling pallet.

An object of the present invention is a resin-filled pallet of a flyback transformer for easily injecting resin by fixing a flyback transformer having a coupling groove in up and down directions formed on one side thereof to a required position, and having a predetermined interval therebetween. A rectangular parallelepiped body having sidewalls spaced apart from each other, and a first coupling portion and a second coupling portion which are installed to face the sidewalls at predetermined intervals and are inserted into the coupling grooves to support the flyback transformer. It is possible to achieve by the resin filling pallet of the flyback transformer, characterized in that it comprises a plurality of support members which are formed to protrude upward and fixing the lower end of the support member to the side wall.

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

3 is a view illustrating a mold case for applying to a resin-filled pallet of a flyback transformer according to the present invention, which is shown in FIGS. In the third case (a), an empty space 22 for coupling a low pressure bobbin or the like is formed in the mold case 20, and a coupling groove 24 having a rectangular cross section is formed on one outer circumferential surface to protrude outward. . This coupling groove 24 is a part coupled to the coupling portion of the pallet according to the present invention described later.

The third (b) mold case 20 is also larger than the third (a) mold case 20, a pair of coupling grooves arranged in the vertical direction facing each other at a predetermined interval and having a U-shaped cross-sectional shape (25) is provided. The pair of coupling grooves 25 are portions coupled to the coupling portion between the front and rear support members described later.

4 is a view showing the resin filling pallet of the flyback transformer according to the present invention, Figure 4 (a) is a plan view, Figure 4 (b) is a side view according to Figure 4 (a) Figure I-I 4 (c) shows the side view.

As shown, the resin filling pallet of the flyback transformer according to the present invention has a rectangular parallelepiped body 50 having sidewalls 52 facing each other at predetermined intervals. The anchoring bolts 54 for loading are respectively installed in the upper four corners of this body 50, and the anchor bolts 54 are coupled to the anchor bolts 54 for height adjustment.

On the inner side of both side walls 52, a plurality of support members 60 are provided along the top of the side wall 52 at regular intervals. The support member 60 is coupled to face the side wall 52 at a predetermined interval. The support member 60 has a first coupling portion 62 and a second coupling portion 64 to which the coupling grooves 24 of the mold case 20 shown in FIG. have. That is, two mold cases may also be mounted on one support member 60.

The first coupling portion 62 and the second coupling portion 64 are constituted by thin plates having a predetermined height in a quadrangular shape, and are disposed to face each other at predetermined intervals. When the first and second coupling parts 62 and 64 are configured in a polygonal shape rather than a circular shape, rotational motion of the mold case coupled thereto is constrained.

The mold case 20 shown in FIG. 3 (b) is coupled to and fixed to the second coupling portion 64 of the front support member 60 and the second coupling portion 62 of the rear support member 60, respectively.

The support member 60 is in the shape of an X-shape as a whole. The configuration of the support member 60 in the form of a bent is to enable the mold case of various specifications to be fixed as necessary. By using the support member 60 of the form as shown, it is possible to fix the mold case 20 of at least two standards as shown in at least the third (a) and the third (b).
