It is composed of

【考案が解決しようとする課題】[Problems to be solved by the device]

ところで、従来の電子部品の端子構造は、薄板帯状の金属板を打ち抜いて端子 を形成しており、打ち抜き用の金型の刃を入れる面に、端子の形状に沿って、図 4〜6に示すような打ち抜き変形部分20が生じることがある。そのため、図6 に示すように、圧電素子10を端子21,22で挟み込んで保持する場合、端子 21は、打ち抜き変形部分20が無い面が圧電素子10に設けられた端子用電極 14に接続され、端子22は、打ち抜き変形部分20がある面が圧電素子10に 設けられた端子用電極15に接続される。 By the way, in the conventional terminal structure of electronic parts, the terminal is formed by punching out a thin strip metal plate, and the surface of the die for punching is inserted into the surface of the terminal along the shape of the terminal as shown in Figs. A punching deformation portion 20 as shown may occur. Therefore, as shown in FIG. 6, when the piezoelectric element 10 is sandwiched and held by the terminals 21 and 22, the terminal 21 is connected to the terminal electrode 14 provided on the piezoelectric element 10 on the surface without the punching deformation portion 20. The surface of the terminal 22 having the punching deformed portion 20 is connected to the terminal electrode 15 provided on the piezoelectric element 10.

【0008】 この時、端子21は、端子用電極14に打ち抜き変形部分20が無い面が接続 されるため、安定して接続される。しかしながら、一方の端子22は、端子用電 極15に打ち抜き変形部分20がある面が接続されるため、端子21が端子用電 極14に接続される部分の面積に比べて、端子用電極15に接続される部分の面 積が小さくなる。そのため、圧電素子10が確実に保持されず、端子22が端子 用電極15から剥離する恐れがあり、その結果、接続不良が生じる恐れがあった 。At this time, the terminal 21 is stably connected to the terminal electrode 14 because the surface without the punching deformation portion 20 is connected. However, since one surface of the terminal 22 is connected to the terminal electrode 15 at the surface having the punched-out deformed portion 20, the area of the terminal 21 connected to the terminal electrode 14 is larger than that of the terminal electrode 15. The area of the part connected to is small. Therefore, the piezoelectric element 10 is not reliably held, and the terminal 22 may be separated from the terminal electrode 15, resulting in a defective connection.

【0009】 本考案は、これらの問題点に鑑みてなされたものであり、電子部品素子に設け られた端子用電極に端子を安定して接続できるようにした電子部品の端子構造を 提供することを目的としている。The present invention has been made in view of these problems, and provides a terminal structure for an electronic component, which enables stable connection of the terminal to an electrode for a terminal provided on the electronic component element. It is an object.

It is characterized in that the deformed portion at the tip of the terminal caused by punching is flattened and made into a substantially flat plate shape.
