Definitions
- the present invention relates to a delay line having a coil and a capacitor.
- LC composite parts such as delay lines and LC filters have a coil wound around a coaxial bobbin, and a lead wire of a capacitor wound around an io terminal pin installed upright on the flange of the coaxial bobbin. Were connected by soldering.
- the fixing strength of the capacitor depends on the connection strength of the lead wire to the terminal pin, so the fixing strength is unstable.
- the present invention provides a recess in a flange of a coaxial bobbin in which a plurality of winding grooves are formed by a plurality of flanges, a terminal pin is implanted in the recess, and a leadless chip tie is provided.
- FIG. 1 is a perspective view of an LC composite component according to an embodiment of the present invention, with a cutaway portion of the same
- FIG. 2 is a cross-sectional view showing an enlarged portion of the same
- FIG. FIG. 4 is a cross-sectional view showing an enlarged portion
- FIG. 4 is a top view of the main portion
- FIGS. 5 and 6 are top views showing an enlarged main portion of still another embodiment.
- 1 indicates that a plurality of flanges 2 are provided at equal intervals and a plurality of winding grooves 3 are formed between the flanges 2.
- a coaxial bobbin made of synthetic resin is used, and a coil 4 is wound around the coil 3.
- a concave portion 5 is provided on the upper surface of the flange 2, and two terminal pins 6 are implanted at both end portions of the concave portion 5 so as to protrude upward.
- a ceramic capacitor having electrodes at both ends is housed in the recess 5 in which the terminal pin 6 is implanted.
- a capacitor 7 having a square shape and a leadless chip type is housed therein. 7 is fixed by electrically and mechanically connecting the electrode a to the terminal pin 6 by soldering.
- the coil 4 and a coaxial bobbin incorporating a capacitor are covered with a case S made of metal.
- Locking ridges 9 are provided on the inner surfaces on both sides of the case 8, and the locking ridges 9 contact the upper surfaces of the flanges 2 at both ends of the coaxial bobbin 1 so that the ceiling surface of the case 8 and the terminal pins 6 are connected.
- the lead wire of the coil 4 is wound around the required terminal pin 6 and soldered, thereby connecting the coil 4 and the capacitor.
- the depth of the recess 5 is the same as the height of the capacitor in FIG. 2, but the depth of the recess 5 protrudes upward by about 1 ⁇ 2 of the height as shown in FIG. By that! ? Part of the connection between the electrode a of the capacitor and the terminal pin 6 is a recess 5! )
- the solder easily adheres to the electrode a of the capacitor and the terminal pin 6. 3 ⁇ 4J ?, good 3 ⁇ 4Soldering It can be performed.
- the heat applied to the coaxial bobbin 1 during the soldering can be reduced, and the coaxial bobbin 1 made of synthetic resin can be prevented from being thermally deformed.
- FIGS. 3 and 4 several ribs 12 for positioning and holding the capacitor in the recess 5 are provided, and the capacitor 7 is pressed into and held by the ribs 12. O to Unishi, and, by providing the O. 2 Peng following small gear-up G between the pin pin 6 and capacitor 7, the soldering is also Unisuruko I performed well until innermost it can.
- the rib 12 a on the terminal pin 6 side is formed to be larger than the rib 12 b on the capacitor 7 side by D, and the tip is on the capacitor 7 side from the terminal bin 6.
- a capacitor 7 can be press-fitted between the two terminal pins 6, and as shown in FIG. 6 may be buried in the coaxial bobbin 1 and only a part may be planted so as to be exposed.
- the chipper's capacitor ′ can be housed in the recess of the flange of the coaxial bobbin, so that it can be made compact. Can be soldered directly, so the capacitor can be fixed with high strength and stable! ), It is possible to improve the quality, and it is easy to assemble it.
