JPS63312606A - High frequency coil - Google Patents

Abstract

PURPOSE:To hold high frequency coils at a predetermined interval in a predetermined direction and to tape them by forming in advance holes to which a plurality of coil holding pins are inserted in the bottom of a base of the coil, and inserting, after its assembling is finished, the pins into the holes. CONSTITUTION:Holding pins 3 of a high frequency coil 1 are taped at a predetermined interval. The base 6 of the coil 1 is formed of insulating synthetic resin, and opened in advance with holes 7 to which the pins 3 are inserted. With this construction, after the coil 1 is finally associated, it is fed to an automatic machine while the direction of the coil remains at it is, the pins 3 taped and cut at the ends are brought into coincidence with the holes 7, and press-fitted therein. Thus, the coil 1 remains constantly in its direction at its position, a tape 4 may be wound on a reel, and may further be contained in a packaging box.

Description

Detailed Description of the Invention (1) Field of Industrial Application The present invention relates to a high frequency coil with multiple terminals used in various electronic devices such as TVs and VTRs. The present invention provides a high-frequency coil that is arranged, held, and taped in a fixed position in a fixed direction so that it can be inserted by an automatic insertion machine into a printed circuit board using a type of component.

(2) Conventional technology Conventionally, high-frequency coils with multiple terminals that are incorporated into various electronic devices have a coil placed on the top surface of a base made of insulating synthetic resin, and a plurality of terminals placed on the bottom surface of the base. A terminal pin is implanted, and a coil terminal is wired and soldered to the pin, and this terminal pin is used for connecting to a printed circuit board and for installation. There are many types of high-frequency coils, including square ones, circular ones, and ones with many irregularities.

(3) Problems to be Solved by the Invention Since these high-frequency coils come in various shapes and have multiple terminals, it is necessary to install multiple terminals in order to incorporate these high-frequency coils into printed circuit boards of electronic devices. Installation had to be done manually by matching the holes.

In particular, it was difficult to assemble and align the inserting position of products with a circular outer shape because automatic machines could not determine their orientation.

(4) Means for Solving the Problems The present invention enables high-frequency coils of each of these shapes to be inserted and assembled into a printed circuit board of an electronic device using an automatic insertion machine using radial lead type parts. This will be explained with reference to the diagram. FIG. 1 is an elevational view showing one embodiment of the present invention, and FIG. 2 is a bottom view of each high-frequency coil, where A is a rectangular coil and B is a round coil. FIG. 3 shows the state in which the holding pin is taped before being inserted into the high-frequency coil, A shows the state before the tip is cut, and B shows the state after cutting. In the figure, 1 is a high frequency coil and 2
It has multiple terminal pins and is used to attach the lid for connecting the high frequency coil. Reference numeral 3 denotes holding pins of the high frequency coil 1, which are taped at regular intervals. 4 is a tape connecting each coil, 4-1 is a mount, and 4-2 is an adhesive tape, and the holding pin 3 is sandwiched between these tapes. 5 is a tape feed hole.

Reference numeral 6 designates the base of the high-frequency coil 1, which is made of insulating synthetic resin, and reference numeral 7 designates a hole pre-drilled therein for insertion of the holding pin 3.

(5) Function Since the present invention has the above-described configuration, after the final assembly of the high-frequency coil 1 is completed, the coil is fed into an automatic machine while maintaining its direction, etc., and is taped and its tip is cut. The holding pin 3 and the insertion hole 7 are aligned and press-fitted. During this press-fitting, heating may be applied if necessary. In this way, the high frequency coil 1
The tape 4 is held constant in its direction and position, and the tape 4 can be wound onto a reel and then stored in a packaging box.

(6) Detailed Description of the Invention According to the present invention, even if the high-frequency coil is multi-terminal and has a rectangular, round, or other complicated shape, it can be placed in a certain direction and at a certain position by an automatic machine. It is possible to tape the parts in the same way as other radial lead type parts, and therefore, when assembling them to the printed circuit boards of various electronic devices, a commonly used automatic taping part mounting machine can be used, which has an extremely large practical effect. It brings about

[Brief explanation of the drawing]

FIG. 1 is an elevational view showing one embodiment of the present invention, FIG. 2 is a bottom view of each high-frequency coil, and FIG. 3 is a taped state of the holding pins.

Claims (1)

[Claims] Holes are prepared in advance on the bottom of the base of the high-frequency coil to insert the holding pins of multiple coils, and after the high-frequency coil is assembled, the holding pins of the multiple coils taped at regular intervals are inserted into the insertion holes. , a high-frequency coil characterized in that the high-frequency coil is held in a certain direction and at a certain interval and taped.
