no. 1 approach

[0126] Figure 1A It is a schematic perspective view showing a capacitor 10 as an electronic component having metal terminals according to the first embodiment of the present invention. The capacitor 10 has a capacitor chip 20 as a chip component and a pair of metal terminals 30 and 40 . The capacitor 10 of the first embodiment has two capacitor chips 20 , but the number of capacitor chips 20 included in the capacitor 10 is not limited as long as it is plural.

[0127]In addition, in the description of each embodiment, a capacitor in which the metal terminals 30 and 40 are mounted on the capacitor chip 20 is described as an example, but the ceramic electronic component of the present invention is not limited to this, and may be a chip other than a capacitor. Electronic components with metal terminals 30, 40 are mounted on the components.

[0128] In addition, in the drawings, the X-axis, Y-axis and Z-axis are perpendicular to each other, such as Figure 1A As shown, the X-axi...

no. 2 approach

[0225] Figure 7 is a schematic perspective view of a capacitor 100 according to a second embodiment of the present invention, Figure 8 , Figure 9 , Figure 10 , Figure 11 They are a front view, a left side view, a top view and a bottom view of the capacitor 100, respectively. Such as Figure 7 As shown, the capacitor 100 is different from the capacitor 10 of the first embodiment except that it has three capacitor chips 20 and the number of first through-holes 36 b included in the first metal terminal 130 and the second metal terminal 140 is different. same. Therefore, in the description of the capacitor 100 , the same reference numerals as those of the capacitor 10 are assigned to the same parts as those of the capacitor 10 , and description thereof will be omitted.

[0226] Such as Figure 7 As shown, the capacitor chip 20 contained in the capacitor 100 and Figure 1A The capacitor chip 20 contained in the shown capacitor 10 is the same. The three capacitor chips ...

Abstract

The invention provides a metal terminal which can stably and reliably connect a plurality of chip components easily and has excellent inhibition effect on wheezing phenomenon, and an electronic component having the metal terminal. The metal terminal (30) is connected to the chips (20) and has a plurality of units (U1, U2). In each of the units, an electrode opposite part (36), a pair of upper arms(31a, 33a) and a pair of lower arms (31b, 33b) which hold the chips from two upper and lower ends thereof, an installation part (38) which is shaped below the lower arms (31b, 33b) in the Z-axis direction of the electrode opposite part (36), and a plurality of projections (36a) which are protruded from the electrode opposite part (36) to the terminal electrodes (22), and are configured in a linearly symmetrical manner relative to a dummy central line OL in the X-axis direction from the center points O1 and O2 of the Z-axis between the upper arms (31a, 33a) and the lower arms (31b, 33b).

Description

technical field [0001] The present invention relates to a metal terminal and an electronic component with the metal terminal. Background technique [0002] As an electronic component such as a ceramic capacitor, in addition to a normal chip component such as a single body directly mounted on a substrate or the like, a component in which a metal terminal is mounted on a chip component as shown in Patent Document 1, for example, has been proposed. [0003] It has also been reported that electronic components mounted with metal terminals have the effect of alleviating the deformation stress received by the chip component from the substrate after mounting or protecting the chip component from impact, etc., and are used in fields requiring durability and reliability. [0004] However, in conventional electronic components with metal terminals, the terminal electrodes of the chip components and the metal terminals are joined only by solder, and there is a problem in this joining. ...
