Embodiment approach 1

[0035] figure 1 is a cross-sectional view showing the configuration of a chip aluminum electrolytic capacitor as an example of the chip electronic component according to Embodiment 1 of the present invention, figure 2 This is an enlarged cross-sectional view of the main part of the chip aluminum electrolytic capacitor. Figure 3A , Figure 3B It is a perspective view of the manufacturing process of the chip aluminum electrolytic capacitor. Figure 4 It is a perspective view of its chip aluminum electrolytic capacitor. figure 1 express Figure 4 The cross-section of the middle Y plane. in addition, Figure 5 It is an enlarged cross-sectional view of a main part of another chip-shaped aluminum electrolytic capacitor according to this embodiment, Image 6 It is an enlarged cross-sectional view of a main part of another chip-shaped aluminum electrolytic capacitor according to this embodiment.

[0036] First, use figure 1 , figure 2The structure of the chip-shaped alu...

Embodiment approach 2

[0071] Figure 7A ~ Figure 8 It is a perspective view of the manufacturing process of the chip aluminum electrolytic capacitor which is an example of the chip electronic component concerning Embodiment 2 of this invention. This embodiment differs from Embodiment 1 in that the end portion 41 a of the lead wire drawn out from the capacitor 45 is not flattened, and the wire material is used as it is. Correspondingly, the shape of the auxiliary terminal 47 at the storage end portion 41 a is also different from that of the auxiliary terminal 17 . That is, the cross section of the exposed portion 47a covering the inner surface of the groove portion 16b of the main body portion 16 is arc-shaped, and the end portion 41a is fitted into the exposed portion 47a. The insulating terminal plate 48 is constituted with such a structure.

[0072] With the above configuration, similarly to Embodiment 1, chip aluminum electrolytic capacitors can be produced extremely rationally, and the visibi...

Embodiment approach 3

[0074] Figure 9A , Figure 9B It is a perspective view of a manufacturing process of a chip aluminum electrolytic capacitor as an example of a chip electronic component according to Embodiment 3 of the present invention; Figure 10A , Figure 10B is an enlarged perspective view of the main part of its chip aluminum electrolytic capacitor; Figure 11A ~ Figure 11C It is an enlarged perspective view of a main part of another chip-shaped aluminum electrolytic capacitor of this embodiment; Figure 12 It is a perspective view of its chip aluminum electrolytic capacitor.

[0075] Figure 9A ~ Figure 10B The difference between the shown chip aluminum electrolytic capacitor and the aluminum electrolytic capacitor in Embodiment 2 is as follows. That is, the protrusion 57 e is provided on the inner peripheral surface of the through hole 57 d of the auxiliary terminal 57 . Furthermore, the protruding portion 57 e is in pressure contact with the outer peripheral surface of the conv...

Abstract

The invention relates to a sheet-shaped electronic component, comprising an electronic component main body and an insulation terminal plate. The electronic component main body comprises a functional element and a pair of leads, and the insulation terminal plate comprises an insulative main portion and an auxiliary terminal made of metal. The main body portion is provided with a first through hole, a groove which is communicated with the first through hole and is formed in a direction vertical to the first through hole, a concave portion formed at the same side of the groove portion, and a projected portion formed in the concave portion. The auxiliary terminal is provided with an explosive portion exposed on the outer surface of the groove periphery and a secondary through hole, and abuts against part of the lead. The leads get through the first through hole, are bent along the right angle at the bottom of the groove, and are contained in the groove. The auxiliary terminal is press connected to be jogged with the projected portion on the insulation terminal plate through the second through hole.

Description

technical field [0001] The present invention relates to a chip-shaped electronic component having excellent vibration resistance. Background technique [0002] In recent years, with the development of electronic control of drive systems and safety system devices of automobiles, the performance and quality for in-vehicle use are also required for electronic components used in these electronic control devices. In addition, miniaturization and productivity rationalization of electronic control equipment are being promoted in order to contribute to improvement of environmental performance and cost reduction. Along with this, sheeting of electronic components is being advanced so that they can be surface-mounted on circuit boards. In addition, highly reliable electronic components having high heat resistance and high vibration resistance, which can also be arranged in an engine room, are expected. use Figure 18 ~ Figure 20 Such a chip aluminum electrolytic capacitor, which is ...
