本考案はトランス等に用いられるEI又はEE型
等の磁気コアを接合一体化するコア固定用ホルダ
ーに関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a core fixing holder for joining and integrating magnetic cores such as EI or EE type used in transformers and the like.
従来、EI又はEE型等の複数の磁気コアを接合
一体化する方法として、2通り有つた。
Conventionally, there have been two methods for joining and integrating a plurality of magnetic cores such as EI or EE type.
即ち、第1の方法は、複数のコアの外周に絶縁
テープを数回巻いて固定する方法である。 That is, the first method is to wrap an insulating tape several times around the outer periphery of a plurality of cores and fix them.
又、第2の方法としては、第4図に示すM字状
の弾性板からなるホルダー1の湾曲部2の弾力
と、先端を折曲げて形成した爪片3,3の係止と
により、第5図に示すように複数のコア4,4

た。 A second method is to use the elasticity of the curved portion 2 of the holder 1 made of an M-shaped elastic plate shown in FIG. 4 and the locking of the claw pieces 3 formed by bending the tips. As shown in Fig. 5, a plurality of cores 4, 4
(The figure shows the EE type.) were integrated into one.
ところが、第1の方法であると、絶縁テープを
巻くのに時間を要すると共に、テープを巻く際
に、コアの接合部がずれるのを防止する手段が必
要であり、組立が困難であつた。
However, with the first method, it takes time to wind the insulating tape and requires a means to prevent the joints of the core from shifting when the tape is wound, making assembly difficult.
又、第2の方法であると、ホルダー1の先端を
一度広げてからコアを装着するので、ホルダー1
の弾力を損うと共に、組立にくく、自動化が困難
であつた。さらに、ホルダー1のたわみ量が一定
せず外形形状が一定しない問題点も有していた。 In addition, in the second method, the tip of holder 1 is expanded once and then the core is attached, so holder 1
In addition to impairing its elasticity, it was difficult to assemble and difficult to automate. Furthermore, there was also a problem that the amount of deflection of the holder 1 was not constant and the external shape was not constant.

According to the present invention, in a holder for integrally fixing a plurality of magnetic cores by elastically joining the holder, the holder consists of an endless frame made of four pieces of elastic plates surrounding the plurality of magnetic cores, and A core fixing holder is obtained, characterized in that a protrusion cut and raised in a direction perpendicular to the two opposing pieces is formed inside the two opposing pieces.
以下本考案を実施例にもとづいて説明をする

体的に方形状を呈し、弾性板から形成されてい
る。そして、対向する辺6,6には内方に突出す
る複数の突起7が形成されている。
The present invention will be described below based on an embodiment. As shown in FIG. 1, the holder 5 of the present invention has an overall rectangular shape and is made of an elastic plate. A plurality of protrusions 7 that protrude inward are formed on the opposing sides 6, 6.
この様に方形状を呈したホルダー5の内側に、
複数のコア4,4を突起7を有する辺6,6に
夫々対応させて弾力に抗して挿入すると、その弾
力によりコア4,4は接合一体化されることにな
る(第2図)。 Inside the holder 5, which has a rectangular shape like this,
When a plurality of cores 4, 4 are inserted against the elastic force so as to correspond to the sides 6, 6 having the projections 7, the cores 4, 4 are joined and integrated by the elastic force (FIG. 2).
尚、組立を容易にするため、突起7の形状を第
3図に示す様に、辺6に直交する方向に切起した
形状が好ましい。即ち、切起した元の方から(図
の下方から上方へ向けて)コアを容易に挿入出来
ると共に、突起7自身も弾性を有し、コアの接合
一体化がより確実になる。 In order to facilitate assembly, the shape of the protrusion 7 is preferably cut and raised in a direction perpendicular to the side 6, as shown in FIG. That is, the core can be easily inserted from the cut and raised side (from the bottom to the top in the figure), and the protrusion 7 itself has elasticity, so that the core can be joined and integrated more reliably.
又、実施例ではコアがEE型をしているため、
ホルダー5は方形状を呈しているが、コアが他の
形状である場合にはその形状に合せた無端形状で
あれば良い。 In addition, in the example, since the core is EE type,
The holder 5 has a rectangular shape, but if the core has another shape, it may have an endless shape that matches the shape.
従つて、コアをホルダーに挿入するだけで接合
一体化出来るので組立が容易になり、自動組立に
は最適である。 Therefore, since the core can be joined and integrated simply by inserting it into the holder, assembly is easy, and it is ideal for automatic assembly.
しかも、ホルダーは無端形状であるから、ゆが
みが無く外形形状が一定になる。 Moreover, since the holder is endless, there is no distortion and the external shape is constant.
以上の様に本考案は、内方に突起を有した無端
形状のコア固定用ホルダーであるから、コアの組
込みが容易になると共に、ゆがみの少ない外形形
状を得ることが出来る等して極めて有用な考案で
ある。
As described above, since the present invention is an endless core fixing holder with an inward protrusion, it is extremely useful because it is easy to assemble the core and it is possible to obtain an external shape with little distortion. This is a great idea.
