Abstract

PURPOSE:To simplify the feeding of the terminal blocks with bobbins of coil parts and to position and hold works with high precision by continuously connecting the terminal blocks by providing connecting sections made of the same resin as that used for forming the terminal blocks to the terminal blocks. CONSTITUTION:A plurality of bobbin sections 12 having split flanges 11 and terminal block sections 13 are continuously connected to each other with connecting sections 15 which are connected to the sections 12 and 13 and have center carrying holes 16 and terminals are forcibly put in and fixed to the terminal block sections 13. In addition, threaded cores are screwed in the hollow sections of the bobbin sections 12. Then windings are wound around the bobbin sections 12 by rotating a flyer with a flyer type coil winding machine and the end sections of the windings are wound around the terminals. After winding, the wound coils are connected to the terminals by soldering by dipping the terminals in molten solder. Then sealing cases are put on the terminal block sections 13 and coil parts are obtained by cutting the connecting sections 15 so as to separate the sections 13 from each other. Through such a series of processes, the coil parts can be manufacture continuously with high productivity.

[0005]

However, in such a manufacturing method, for example, in the case of winding, one nozzle 2 is provided for each nozzle 2.
Since only one terminal board with bobbin 1 can be wound,
It is necessary to supply the terminal board with bobbin 1 for each piece, and in the case of manual work, the supply of the terminal board with bobbin 1 cannot keep up with the speed of the winding machine, or even if the supply of the terminal board with bobbin 1 is automated There were problems such as high costs.

Similarly, when assembling the screw type core 5 and fitting the shield case 7, it is necessary to perform supply and withdrawal one by one, so that work efficiency cannot be improved, and even if it is automated, equipment cost becomes high. There was a problem.

The present invention solves such a problem, simplifies the supply of a terminal board with a bobbin, obtains a highly accurate work positioning and holding accuracy, and is a low cost and highly productive coil component. It is an object of the present invention to provide a manufacturing method of.

[0008]

The technical means of the present invention for solving the above-mentioned problems is a bobbin-equipped terminal plate for a coil component having a bobbin portion on the upper part of a terminal plate in which a plurality of terminals are embedded. In addition, a connecting part made of the same resin as the terminal board with bobbin is provided to make it continuous, and multiple series of processing such as terminal assembling, winding and wiring, core assembling, and coil and terminal soldering can be performed. This is a method in which continuous operation is performed using bobbin-equipped terminal boards that are continuously connected.

[0009]

The function of this technical means is as follows.

That is, by providing a connecting portion on the bobbin-equipped terminal plate and forming a plurality of continuous portions, it becomes an operation equivalent to supplying a substantially large number of parts in one supply, and simplifies the supply operation. be able to.
