The inner side wall 62 of the bending plate 6 is provided with a supporting member 64 facing the inner side wall 62 at a predetermined interval. The front face of the support member 64 has an inverted T-shape as shown in FIG. 4 (b). The supporting member 64 is inserted into the coupling groove 24 of the mold case of FIG. 3 to support the mold case, and a plurality of supporting members 64 are provided at predetermined intervals along the inner wall 62 of the bending plate 60. . The support member 64 may be configured in various shapes as necessary, but it must have a cross-sectional shape corresponding to the shape of the coupling groove, and the polygonal cross-sectional shape is not allowed to allow the mold case to be rotated while inserted into the coupling groove. It should be configured to have. The supporting member 64 is fixed to the inner side wall 62 of the bending plate 60 through the fixing means 66 such as two bolts.

As shown in FIG. 4, the pallet requires a large number of supporting members 64 to be manufactured separately. In addition, each support member 64 is to be installed at the correct intervals, it takes a lot of time and it is difficult to equalize the intervals between the respective support members 64. In addition, since each of the supporting members 64 must be installed as the respective fixing means 66, a lot of fixing means are required and the fastening force is weak.

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 an inner wall spaced apart from each other, and a plurality of support portions installed to face the inner wall at a predetermined interval apart from each other and inserted into a coupling groove to support the flyback transformer at a predetermined interval upwards. It is possible to achieve by the resin filling pallet of the flyback transformer, characterized in that it comprises a fixing means for fixing the lower end of the integral support member and the integral support member formed to protrude to the inner wall.

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

5 is a view showing a resin-filled pallet of the flyback transformer according to the present invention, a half-width planar view in FIG. 5 (a), and a front view according to FIG. 5 (a) in FIG. 5 (b) in FIG. 5 (c) is a view showing half-width side views, respectively. As shown in FIG. 5, the resin filling pallet according to the present invention includes a body 50. The body 50 has a rectangular parallelepiped shape as a whole. At the upper edge of the body 50, a mounting anchor bolt 52 is installed. The anchor bolts 52 are respectively installed at the top four corners of the body 60. The anchor bolt 52 is coupled to a nut 54 for height adjustment.

The bending plate 60 bent in a predetermined shape is attached to both upper edges of the body 50. The inner wall 62 of the bending plate 60 is provided with an integral support member 70 facing the inner wall 62 at predetermined intervals. The front view of the integrated support member 70 can be seen from the fifth (b). The integrated support member 70 has a plurality of support portions 72 formed to protrude upward at a predetermined interval as shown in FIG. 5 (b). Each of the supporting parts 72 is inserted into the coupling groove 24 described in FIG. 3 to support the flyback transformer. The lower end of the unitary support member 70 is integrally connected to a plurality of support portions 72, and is fixed to the inner wall 62 by a plurality of fixing means (74). As the fixing means 74, a bolt or the like is used.

As can be seen in FIG. 5, the integral support member 70 is manufactured by processing a long and narrow flat plate. Unlike the related art, the integrated support member 70 does not need a cutting process and forms a groove between the two support portions 72 and fixes the fixing means ( What is necessary is just to form many coupling holes 76 for engaging 74. Of course, the number of the coupling holes 76 may be much smaller than in the prior art, and the fixing means 74 such as bolts also require much less.
