Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic component for taping used when automatically mounting electronic components used in various electronic devices on a printed circuit board.

2. Description of the Related Art Electronic components for taping must be structured so that they can be mounted on an automatic mounter by connecting them to tape.

Problems to be Solved by the Invention Therefore, long lead legs, which were not present in conventional electronic components, are required, and a very large loss occurs in terms of material yield. In addition, because the lead legs are long, they are not mounted on conventional electronic component assembly machines and require specialized equipment, which is a major obstacle to production. Also, because the lead legs are stipulated, dedicated parts are required and they are inexpensive. It was difficult to supply electronic components for taping.

It is an object of the present invention to eliminate the above drawbacks and provide an inexpensive electronic component for taping.

Means for Solving the Problems To achieve this object, the taping electronic component of the present invention uses an electronic component mass-produced at low cost as a standard product, and the bottom surface of the electronic component is manufactured according to the specification. An extension lead leg for taping, which is different from the lead terminal of the component, is attached, and the tip of the lead leg is fixedly adhered to the tape.

With this structure, inexpensive standard electronic components can be used, and lead legs can be freely formed according to the specifications. Therefore, a large-scale dedicated assembly machine is not required, and an inexpensive electronic component for taping is provided. be able to.

Embodiment Next, an embodiment of the present invention will be described with reference to FIGS. In the figure, in addition to the lead terminals 2 of the electronic component 1, a U-shaped extension lead leg 3 for taping is attached to the bottom surface portion 4 of the electronic component 1, and the tip of the lead portion 3a of the extension lead leg 3 is attached. A tape 5 is attached to the portion 5 with an adhesive tape 6. The electronic component 1 for taping is configured by continuously fixing the electronic component 1 to the mount 7 for taping with a constant feeling. Reference numeral 8 is a parrelot hole to be sent by the mounting machine.

Here, the bottom surface portion 4 of the electronic component 1 is provided with a rectangular mounting hole 9 for the extension lead leg 3. The extension lead leg 3 is now made of a U-shaped metal plate material having a wide central portion 10. Widened central part of extension lead 3
10 is inserted into the mounting hole 9, and the wall portion 11 of the mounting hole 10 is melted and fixed to the bottom surface portion 4 of the electronic component by caulking by applying heat. The central portion 10 of the extension lead leg 3 has a wide width in order to stabilize the attachment of the central portion 3 and prevent rattling after coupling. The extension lead legs 3 are specifically made of iron, copper, brass or the like. Further, when a metal round bar is used to form a U-shape, the portion of the bottom of the U-shape portion that abuts the bottom of the electronic component 1 may be crushed to be wide.

EFFECTS OF THE INVENTION As described above, according to the present invention, the central wide portion of the U-shaped extension lead foot having the wide central portion and the lead portions on both sides is brought into contact with and fixed to the bottom portion of the electronic component. By doing so, two leads dedicated to taping can be attached to the electronic component at one time, improving productivity, and extending the wide part by abutting and fixing to the bottom of the electronic component. The lead foot can be attached without rattling. Further, in the present invention, an inexpensive electronic component for taping can be supplied by attaching a separate long extension lead foot for taping to an electronic component which is produced as a standard product at a low cost by a standard machine. Also, because it is configured without changing the lead terminals and other components of the electronic components,
The conventional characteristics of the electronic component are maintained as they are. As an example of use, the conventional printed circuit board can be used by simply adding two holes for the taping lead leg (the extension lead leg is a lead terminal of the electronic component). And it does not require copper foil wiring because it is a dummy terminal that is independent and has no electrical continuity).
