力で接触する。2. Description of the Related Art Usually, the terminal treatment of the windings of a transformer or choke coil is carried out by entwining it with a pin formed on a bobbin. Then, in order to improve the production efficiency, an electric wire may be wound around the bobbin by an automatic winding machine and end treatment may be performed. However, in the case of such automatic winding, since various treatments are performed with a predetermined tension applied to the electric wire, the wire extends from the end of the winding to the pin in a taut state, and the bobbin collar The edge of the part is contacted with a predetermined pressure.

ゲピン径を太くする等があった。Therefore, after manufacturing, external stress such as vibration and thermal expansion causes stress to be applied to the electric wire, particularly to the contacted portion with the bobbin collar portion and the end-treated portion such as the portion wound around the carrageen pin. Then, in the case of a thin wire, there is a high possibility that the wire will be broken due to the stress. So, as a countermeasure,
There was a thickening of the wire, a double or triple thin wire, and a thicker carrageen pin.

策では十分ではない。However, with the measures described above, the thin wire is no longer used, and the original purpose of using the thin wire cannot be achieved, resulting in a fall. Further, even if the diameter of the carrageen pin is increased, the edge contact portion of the bobbin collar portion may be cut at all, and the above countermeasure is not sufficient.

すると、工数がかかり、価格アップにつながる。Therefore, it is conceivable to give a slack to the electric wire between the bobbin winding portion and the bobbin collar portion. However, since the slackening cannot be performed by the current automatic winding machine, The slack will be done by hand winding.
Then, it takes man-hours and leads to price increase.

After that, remove the slackening line to make slack. Therefore, it is possible to manufacture by using existing equipment almost as it is with only a minimum process change of forming a protrusion and removing the slackening line after attaching the protrusion to the protrusion. After the manufacturing, the protruding portion serves as an abutting portion (a leg portion for floating a predetermined distance in order to prevent the electric wire from coming into contact with the circuit board) when the present component is mounted on the circuit board.

2 and FIG. 2 show a state in which the method for twisting the electric wire of the transformer according to the present invention is performed. In the figure, reference numeral 1 denotes a trans-bobbin having a substantially H-shaped plane, a bobbin winding portion at its middle portion, bobbin collar portions on both sides thereof, and an upper edge surface portion of the bobbin collar portion along the bobbin axis is thick-walled. Is formed as a terminal processing edge frame portion 2, and a plurality of pins 3 are planted in the edge frame portion 2. The terminal processing edge frame portion 2 is further provided with two projecting portions 4 and 5 inside the plurality of pins 3 and outside the outermost pins 3a and 3b. A slackening wire 6 can be stretched in advance in a direction intersecting the electric wire between the terminal processing edge frame portion 2 and the pin 3 of the terminal processing edge frame portion 2. In this embodiment, the protrusions 4, 5
Are provided at both ends of the innermost edge of the edge frame portion 2 for terminal processing.

末処理用縁枠部２のピン３に巻付けられる。In the present invention, in order to impart slack to the winding to be processed, as shown in FIGS. 1 and 2, first, the slackening wire 6 is entangled with the two protrusions 4 and 5. , It is stretched between both protrusions 4 and 5. Then, a winding wire 7 made of a thin wire of, for example, 0.1 mm is wound around the intermediate winding portion of the bobbin 1 as usual. It is wrapped around 3.

る。At this time, the wire end portion 8 passes over the slackening wire 6 stretched between the projections 4 and 5 in a supported manner. Therefore, as shown in FIG. 3A, the wire end portion 8 is held by the slackening wire 6 at a height position slightly apart from the surface of the terminal processing edge frame portion 2.

に示す。Then, when the slackening wire 6 is removed after the winding is finished, a desired slack is created at the wire end 8. For comparison, the above-mentioned protrusions 4,
5 and the conventional case without the slackening wire 6 are shown in FIG.
Shown in.

あっても切断されるおそれがない。According to the above manufacturing method, the slackening wire 6 is stretched before the terminal treatment, and the wire 6 after the terminal treatment is applied.
Ordinary winding treatment and terminal treatment can be performed except that the wire is removed, and even if various treatments are performed while applying tension by an automatic winding machine, the wire end has a slackening wire 6
However, since there is a predetermined space between the line 6 and the surface of the edge frame portion 2 for terminal processing,
If the line 6 is removed, slack can be created in the tangle due to the space. Therefore, even if an external stress is applied to the pin portion, the winding portion, etc. after manufacturing, no tension is directly applied to the terminal-treated electric wire, and even a thin wire is not likely to be cut.

The point that a plurality of pins 3 are planted in the upper edge surface portion of, that is, the surface portion along the bobbin axis of the bobbin collar portion is the same as the above-described embodiment. However, this embodiment is different from the above in that the terminal processing edge frame portion 2 is formed with a groove 9 so as to traverse between the pins 3 and the terminal processing edge frame portion. A plurality of pins 13 made of the same conductor as the above-mentioned pin 3 are also projected on the side surface portion of 2, that is, the end surface portion intersecting the bobbin axis.

That is, the winding 7 is wound around the intermediate winding portion of the bobbin 1 as usual, and the wire end 8 of the winding 7 passes through between the upper surface pins 3a and 3b of the terminal processing edge frame portion 2. It is wound around the side pin 3. After the winding is finished, slack is made by slackening wires.

The slackening wire 6 stretched between them is supported by the slackening wire 6 to get over it. Therefore, as shown in FIG. 6B, the wire end portion 8 is held by the slackening wire 6 at a height position slightly apart from the surface of the terminal processing edge frame portion 2. Even when the slackening line 6 is stretched at the same height as the surface of the edge processing edge frame portion 2, when viewed from the bottom of the groove 9, the slackening line 6 is slackened above the groove 9 between the pins 3a and 3b. The wire 6 is stretched, and the wire end portion 8 is present so as to be supported on the slackening wire 6.
