Abstract

The utility model relates to a ceramic capacitor which comprises a capacitor body, wherein two pins are led out of the capacitor body, each pin comprises a leading-out section and a mounting section, the two ends of each leading-out section are respectively connected with the capacitor body and the corresponding mounting section, and the cross section area of the leading-out sections is larger than that of the mounting sections. Compared with the prior art, the strength of the leading-out sections can be ensured because the cross section area of the leading-out sections is larger than that of the mounting sections and the leading-out sections are thicker so as to better support the weight of the capacitor body; and simultaneously, the mounting sections are thinner so as to facilitate the mounting of the ceramic capacitor during the use.

Description

A kind of ceramic capacitor

Technical field

The utility model relates to a kind of ceramic capacitor.

Background technology

Ceramic capacitor particularly multicore group ceramic capacitor is widely used at military project, civil area because capacity is big; Its manufacture process is to adopt a lead frame; Be provided with pin and welding rib in the lead frame; With chips welding on the welding rib, then with Chip Packaging, make ceramic capacitor after cutting muscle and removing the lead frame waste material.The structure of the performance of the ceramic capacitor that makes and the encapsulation of chip, pin etc. all has very big relation; Structural design such as pin is just very crucial; Should guarantee that certain intensity is with supporting chip; Be convenient to again install, but pin of the prior art design can't take into account this 2 requirements usually, designs unreasonable.

The utility model content

The main purpose of the utility model is to overcome the shortcoming of prior art, and a kind of ceramic capacitor is provided, and design takes into account intensity and the requirement of being convenient to install to pin more to satisfy ceramic capacitor.

The utility model adopts following technical scheme:

A kind of ceramic capacitor; Include capacitor body, this capacitor body leads to two pins, and this pin includes the section of drawing and construction section; The two ends of this section of drawing connect this capacitor body and this construction section respectively, and the cross-sectional area of this section of drawing is greater than the cross-sectional area of this construction section.

The cross-sectional area of the said section of drawing is the twice of said construction section cross-sectional area at least.

The changeover portion that has inclination between said section of drawing and the construction section.

Said capacitor body by the welding rib that links to each other with said pin, be welded on the plurality of chips on this welding rib and be encapsulated in the outer packaging plastic of this chip and form.

Can know by above-mentioned description the utility model; Compared with prior art; A kind of ceramic capacitor of the utility model since the cross-sectional area of the section of drawing greater than the cross-sectional area of construction section, the section of drawing more slightly can guarantee the intensity of the section of drawing, to support the weight of capacitor body better; Construction section is thinner simultaneously, the installation when making things convenient for ceramic capacitor to use.

Description of drawings

Fig. 1 is the structural representation of a kind of ceramic capacitor embodiment of the utility model;

Structural representation when Fig. 2 does not encapsulate packaging plastic for a kind of ceramic capacitor embodiment of the utility model.

Embodiment

Below the utility model is done further to describe through embodiment.

See figures.1.and.2, a kind of ceramic capacitor of the utility model includes capacitor body 10, and the two ends of capacitor body 10 lead to two pins 20, and pin 20 comprises the section of drawing 21, the changeover portion 22 and the construction section 23 that tilt successively by its root; Capacitor body 10 by the welding rib 11 that links to each other with pin 20, be welded on welding on the rib 11 plurality of chips 12 and be encapsulated in chip 12 outer packaging plastics 13 and form.

See figures.1.and.2, in the utility model, the cross-sectional area of the section of drawing 21 is the twice of construction section 23 cross-sectional areas; The section of drawing 21 more slightly can guarantee the intensity of the section of drawing; To support the weight of capacitor body 10 better, construction section 23 is thinner simultaneously, the installation when making things convenient for ceramic capacitor to use; In addition, have the changeover portion 22 of inclination between section of drawing 21 and the construction section 23, make pin 20 overall structures more firm, reliable.

An above-mentioned embodiment that is merely the utility model, but the design concept of the utility model is not limited thereto allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading the utility model protection range.
