Description of the Related Art Conventionally, this type of transformer has been constructed by winding a copper wire around a bobbin 4 having a lower end collar 3 and a lower end collar 2 to form a winding 6, as shown in FIGS. 3 and 4. The lead wires 7 at both ends of the wire 6 are led out through the lead-out groove 8 and wound around the metal bottle terminal 5, and then soldered and connected to the bobbin 4 with a magnetic material 1 made of a laminated iron core or the like.
It was configured by inserting . 5 and 6 are diagrams showing a conventional method for attaching the metal pin terminal 5. The lower end collar 2 is provided with a pin hole 9, and the metal pin terminal 5 is inserted into the lower end flange 2. The metal bottle terminal 5 is inserted from the lower surface of the collar 2 and attached by bending to the side, and the metal bottle terminal 5 is provided with a crusher 10 for holding and fixing the metal bottle terminal 5 to the lower end collar 2.
このつぶし１０の形状は第７図ａ−Ｃに示すように円柱
の一部に偏平部を設けた形状になっている。The shape of this crushing 10 is such that a flat portion is provided in a part of a cylinder, as shown in FIGS. 7a-C.

得られなかった。Problems to be Solved by the Invention In this transformer, the lead wire 7 is wound around the metal pin terminal 5 implanted in the lower end collar 2 of the bobbin 4 and connected by soldering. If it moves, there is a risk of wire breakage or short-circuiting with the magnetic material 1, so the metal pin terminal 5 is required to be strong against the load. However, in the structure of a conventional transformer, the bottle pushing strength is large (variations, and sufficient strength cannot be obtained) due to variations in the crushed diameter, variations in the bottle hole diameter, etc.
そこで本発明は、従来の金属ビン端子５をつぶして保持
する方法から、金属ビン端子５を上下から圧縮すること

る。Therefore, the present invention provides a ring-shaped protrusion around the circumference of the metal bottle terminal and uses the protrusion as a stopper by compressing the metal bottle terminal 5 from above and below, instead of the conventional method of crushing and holding the metal bottle terminal 5. By doing so, the bottle pushing strength can be improved, the quality can be improved, and the size of the bottle can be reduced, so that the size of the bobbin can be reduced.
問題点を解決するための手段
上記問題点を解決するための本発明の手段は、金属ビン
端子の任意の位置の円周上に、リング状突起部を設けて

により、ボビンの下端鍔をはさみ込む構成にするもので
ある。Means for Solving the Problems The means of the present invention for solving the above problems is to provide a ring-shaped protrusion on the circumference of a metal bottle terminal at an arbitrary position, and to connect the ring-shaped protrusion and the metal bottle. The lower end collar of the bobbin is sandwiched between the bent points of the terminal.

ない限り、金属ビン端子が動かず、断線も磁性材とのシ
ョートも、起こらないことになる。Effect The effect of this means is as follows. In other words, even if a pushing load is applied to the metal bottle terminal, there is a ring-shaped protrusion on the metal bottle terminal, and this ring-shaped protrusion hits the bottom surface of the bottom flange of the bobbin, so unless the bobbin breaks, the metal bottle will not break. This means that the terminals do not move, and neither disconnections nor short circuits with magnetic materials occur.

The transformer, which is soldered to the bent tip of the bobbin 15, is pushed into the metal pin terminal 15 due to the load (bobbin 14
A force is applied from the lower surface of the lower end collar 12 toward the upper surface. In that case, since the ring-shaped protrusion 20 of the metal bottle terminal 15 hits the lower surface of the lower end collar 12 as a stopper, the metal bottle terminal 15 will not move unless the bobbin 14 is broken, and the metal bottle terminal 15 will not move due to the displacement of the metal bottle terminal 15. Contact or lead with magnetic material 11! ! 1!17 wire breakage does not occur. Further, since the holding and fixing strength of the metal bottle terminal 15 is not affected by the bottle embedding size unlike the current bobbin, the thickness of the lower end collar 12 of the bobbin 14 can be made thinner.
