The present invention relates to a chip-type coil which is arranged parallel to each other at positions deviated from each other, a portion of which is pressed into a hole formed in an end surface of a drum core and fixed, and which has a flat cross section.

時、板状体６はチップ型コイル１の傾き防止に使用され
る。A rectangular plastic plate 6 is attached to the center of the flange 3 which is the end surface of the drum core. On both sides of the plate-shaped body 6, both ends 5a, 5b of the coil 5 are provided.
Are arranged on the flange 3 as terminals 5c and 5d. When the chip coil 1 of No. 2 is attached to the circuit board (not shown), the state of FIG. 3 is reversed, that is, the flange 3 is directed downward and the terminals 5c and 5d are placed on the conductive pattern of the board.
Correspondingly, by assembling and passing through a reflow oven, soldering is performed with the previously prepared cream solder. At this time, the plate-like body 6 is used to prevent the tip-shaped coil 1 from tilting.
上記従来例によれば、チップ型コイルの傾き防止の為に
板状体６を必要とし、この分部品点数も増える事にな

槽へ漬けておかなければならない。According to the above-mentioned conventional example, the plate-like body 6 is required to prevent the inclination of the chip type coil, and the number of parts is increased accordingly. In addition, the work of attaching the plate-shaped body 6 is also required, which increases the cost. Moreover, since the terminals 5c and 5d are only bent to the side surface of the flange 3, they will move easily if they touch the terminals 5c and 5d, and when they are assembled on the board, they will be dislocated from the wiring pattern and will not interact with each other. Cannot be connected. The cross-sectional shape of the terminals 5c and 5d on the side surface of the flange 3 is circular. That is, the coil ends 5a and 5b are solder-dipped in a dip bath and bent to the side surface of the flange 3.
Since the coil 5 is insulated and coated with enamel or the like, even if the terminals 5c and 5d are to be solder-dipped in the solder dip tank, they must be immersed in the dip tank for a long time before the solder dipping is completed.
又、逆にディップ時間を短時間で済まそうとすると、半

パターンとの半田付が不完全となり、信頼性を損う。On the contrary, if the dipping time is shortened, the solder dipping becomes incomplete, so that the soldering with the wiring pattern of the circuit board becomes incomplete and the reliability is deteriorated.
本考案は上記従来の課題を解決したチップ型コイルを提
供する事を目的とする。An object of the present invention is to provide a chip-type coil that solves the above conventional problems.

する。The chip-type coil according to the present invention is a chip-type coil in which two ends of a coil wound around a drum core are led out to the end surface of the drum core as terminals, and the two terminals are respectively displaced from the axis of the end surface. Placed parallel to each other,
A part of the terminal is pushed into a hole formed in the end surface of the drum core and fixed, and the terminal has a flat cross-sectional shape.

できる。As in the above configuration, since the two terminals are arranged in parallel with each other at positions displaced from the axis of the end face, respectively, when placed on the substrate, the chip type coil is not tilted and is mounted upright. Also, since a part of the coil end is inserted and fixed in the hole formed in the end surface of the drum core, the coil end can be securely fixed. Furthermore, by making the terminal part flat, the coil coating When the solder dip bath is immersed in the solder dip bath, the solder dip can be performed easily in a short time.

The chip-type coil 11 has a structure in which the coil 15 is wound around a drum-shaped drum core 12 that is formed in a zigzag shape. Reference numerals 13 and 14 are flanges, and recesses 13a, 13b and 14a, 14b are formed on their outer circumferences, respectively. The winding start end of the coil 15 has a concave portion 13a at 15a.
Is disposed as a terminal 15c at a position slightly distant from the shaft center on the surface of the flange 13 which is the end surface of the drum core 11 via. Similarly, the winding end end 15b of the coil 15 is also provided with the recess 1
Terminal 15 with the shaft center sandwiched between the upper surface of the flange 13 and the flange 3
It is arranged parallel to c.

着き、短時間にそれを行う事が出来る。The terminals 15c and 15f, which are arranged on the end surface of the drum core 12 (side surface of the flange 13), are formed in a flat shape. That is, the terminal 15c has a shape as shown in FIGS. 2 (a) and 2 (b).
And the cross section of 15d is formed. By cutting off the one-dot chain line portion of the same figure (a), it may be a cross-sectional shape shown in the same figure (b), or by applying pressure to the one-dot chain line portion, crushing, in the same figure (b) You may form like. Second
In the method of scraping off the one-dot chain line part in FIG. (A), the conductive part (copper material) of the coil 15 is exposed in the scraped off part, so that the terminals 15c, 15 thus formed are formed.
When d is dipped in the solder dip tank, the solder easily reaches the surface and can be done in a short time.

First, the coil end 15a is formed in the recess 13a of the drum core 12.
Is fixed and the coil 15 is wound. Next, when the winding is completed, the winding end end portion 15b is fixed to the concave portion 13b.
Next, the cross section of the portion to be the terminals 15c and 15d is formed into a flat shape by any of the above-mentioned methods, and then solder dip is performed, and the side surface of the flange 13 is bent and fixed.

15d is led out to the upper surface of the flange 13 through the grooves 13a and 13b, and the terminals 15c and 15d are arranged so as to be opposed to each other in a direction parallel to each other at a position slightly offset from the axis. When the chip type coil 11 is placed on the wiring pattern of the circuit board, the terminal 15
Since the drum core 12 is supported by the c and 15d, the chip type coil 11 can be stably erected on the substrate.

確実に行う事ができる。According to the chip-type coil of the present invention described above, the chip-type coil can be stably erected upright without being inclined to the substrate by only the terminal led out to the upper surface of the flange. Therefore, it is possible to eliminate the need for the plate-like member that has been conventionally attached for preventing tilting, reduce the number of parts, and eliminate the work for attaching the plate-like member. In addition, if the terminal is touched during transportation of the chip type coil or during assembly work on the board (requires extreme caution and poor workability),
In the conventional type, the terminals are deformed and the reliability of the chip type coil after assembling is impaired. However, the chip type coil according to the present invention can improve the assembling workability and reliability. Further, since the terminal portion has a flat cross-sectional shape, solder dipping can be reliably performed in a short time.
又、偏平形とした事により、チップ型コイルの高さ寸法
