Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a backing case for a transformer that can be used for transporting a transformer, the structure of a conventional example, and its problems. Show the case. As shown in the figure, a valve-shaped partition 2 made of cardboard or resin molding is incorporated into an exterior case 1. In recent years, among electronic components, parts such as transformers and coils have become mainstream with pin terminals, which are suitable for rationalization, in order to reduce costs. parts like this,
If the product is packaged in a valve-shaped container, quality defects such as bent pins may occur during transportation, so a cushioning material such as styrofoam is used for protection. This is costly and does not provide complete protection.

OBJECTS OF THE INVENTION In view of the above-mentioned drawbacks, the present invention provides a backing case for a transformer that can sufficiently protect the product without using a cushioning material or the like. The cardboard and unprocessed cardboard have punched holes in the direction perpendicular to the notches that hold and fix the core part, which has strong mechanical strength, in the transformer, avoiding the coil and terminal parts, which have weak strength. In this method, an inner partition with a concave portion attached so that the flute directions are perpendicular to each other is used, and a low-alloy transformer core portion is connected to the side wall of the concave portion, and the lower or upper and lower surfaces are used for protection.

DESCRIPTION OF EMBODIMENTS Below, a backing case for a transformer according to an embodiment of the present invention will be explained with reference to the drawings. Figure 3 shows a notch 3 that holds and fixes the core 1o of the transformer 13, and a notch 4 that avoids the coil 11 and the terminal 9. An inner partition 8 is created by pasting together a cardboard 6 with punched holes 6 and an unprocessed cardboard 7 so that the directions of the cardboard flutes 14 are perpendicular to each other. FIG. 4 shows an example of packaging the transformer 13. The transformer 13 is inserted into the recess 12 formed by the punched hole 6 of the partition 8 arranged at the bottom of the outer case 16. After a predetermined number of transformers 13 are assembled in this way, the above-mentioned partition 8 is placed over the transformer 13, and the lid 16a of the outer case 16 is closed to complete the packaging.

By packaging in this manner, the transformer core 1o is fitted into the recessed side wall 15 to protect and fix the transformer core 1o against movement in the front, back, left, and right directions, and the lid 16a of the outer case 16 can be closed against vertical movement. It is protected by

Effects of the Invention As described above, the backing case of the present invention is made by pasting cardboard flutes orthogonally to unprocessed cardboard and cardboard having punched holes made by notches for holding and fixing the transformer core and notches for avoiding coils and terminals. By using an inner partition with a recess, and inserting and fixing the transformer into the recess of the inner partition, it is possible to protect locally weak parts such as the coil and terminals from being subjected to external forces.
Furthermore, since the corrugated cardboard flutes are pasted together in perpendicular directions, the strength of the partition itself is strong, high quality is maintained, and there is no need to use cushioning materials, making it easy to work and can be packaged at low cost.
