Abstract

The utility model provides a capacitor which comprises a capacitor body, a positive pole pin, and a negative pole pin. A side wall of the capacitor body is provided with the positive pole pin and the negative pole pin. The positive pole pin and the negative pole pin are plate-shaped. A hole site is arranged on the mainboard for accommodating the capacitor body; the capacitor is arranged inside the hole site; and protruding ends of the positive pole pin and the negative pole pin are respectively connected with the mainboard by welding. According to the utility model, the pin position of the capacitor is changed; the hold site is arranged on a PCB mainboard so that the capacitor can be arranged on the mainboard; the pin is weld with the mainboard, so that the thickness, the height permitted at the top and the height permitted at the bottom of the PCB are taken full advantage to place the capacitor with the quite high height; the need of the light and thin notebook is met; and the thickness, the height at the top and the height at the bottom of the mainboard are taken full advantage to heighten the polymer aluminum or tantalum capacitor so as to increase the capacitance of the high pressure-resistant value.

Description

A kind of electric capacity and use the mainboard of this electric capacity

Technical field

The utility model belongs to light and thin type mainboard and electric capacity, is specifically related to a kind of electric capacity and uses the mainboard of this electric capacity.

Background technology

Polymer aluminium or the tantalum electric capacity of jumbo high withstand voltage are generally highly higher now, and some computers, notebook, all-in-one AIO, the PC such as desktop computer are toward the development of frivolous direction, and the limit for height of mainboard front or reverse side is generally lower, requires the element heights on mainboard more and more lower, the height of electric capacity, the electric capacity of especially high withstand voltage high power capacity has no idea to be placed on mainboard, and this becomes the bottleneck of current techniques development.

The utility model content

The technical problems to be solved in the utility model is to provide a kind of electric capacity, changes shape and the position of the both positive and negative polarity pin of electric capacity, the technical development of current frivolous PC preferably.

Another technical problem to be solved in the utility model is to provide a kind of mainboard, and the position, hole of mating with above-mentioned electric capacity is set on mainboard, makes computer, notebook, all-in-one AIO, and the PC such as desktop computer are more frivolous.

For achieving the above object, the utility model by the following technical solutions:

A kind of electric capacity comprises electric capacity main body and both positive and negative polarity pin, and the sidewall of described electric capacity main body arranges the both positive and negative polarity pin, and described both positive and negative polarity pin is tabular.

Preferably, described both positive and negative polarity pin stretches out upwards respectively arrange vertical with sidewall after the sidewall bending from electric capacity main body bottom surface.

Preferably, described both positive and negative polarity pin is symmetrical and be arranged on the middle part of electric capacity main body wall respectively.

Preferably, described electric capacity is patch-type polymer electric capacity, electrochemical capacitor or ceramic condenser.

A kind of mainboard is provided for the position, hole of accommodating electric capacity main body on described mainboard, above-mentioned electric capacity is arranged in position, described hole, and the both positive and negative polarity pin of described electric capacity and sidewall vertical section weld with mainboard respectively.

The utility model compared with prior art has the following advantages:

The welding pin pad of tradition electrochemical capacitor is the bottom at electric capacity, the both positive and negative polarity pin pad of traditional polymer electric capacity is at the place, two ends, bottom of electric capacity, so they can only be placed on top TOP or the following bottom of mainboard, the utility model changes the Pin locations of electric capacity, on the PCB mainboard by the position, hole is set, the electric capacity main body by with the sidewall vertical section can frame on mainboard, and weld with mainboard, can take full advantage of like this thickness of PCB and the limit for height of TOP and bottom and put highly very high electric capacity, solve the demand of frivolous notebook; The height that can also take full advantage of mainboard thickness and TOP and bottom is done the capacitance that height increases high withstand voltage to polymer aluminium or tantalum electric capacity.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described further:

Embodiment 1

As shown in Figure 1, 2, 3, the present embodiment is polymer electric capacity, comprise electric capacity main body 1 and both positive and negative polarity pin 2, the sidewall of described electric capacity main body 1 arranges both positive and negative polarity pin 2, described both positive and negative polarity pin 2 is dull and stereotyped, described both positive and negative polarity pin 2 is symmetricly set on the middle part of electric capacity main body 1 sidewall, and or near normal vertical with sidewall.

During use, as shown in Figure 4, position, hole 4 is set on PCB mainboard 3, electric capacity by 2 of both positive and negative polarity pins vertical with sidewall on mainboard 3, both positive and negative polarity pin 2 respectively with mainboard 3 welding, be arranged on the middle part of electric capacity main body 1 due to both positive and negative polarity pin 2, thus, electric capacity can be set on mainboard, can take full advantage of like this thickness of PCB and the limit for height of TOP and bottom and put highly very high electric capacity, solves the demand of frivolous notebook.

Embodiment 2

As shown in Fig. 4,5,6, the present embodiment is electrochemical capacitor, and difference from Example 1 is, electrochemical capacitor is cylindrical.

The utility model above-described embodiment is only this patent execution mode preferably, and the structure that all employing the technical program are described, feature and the variation on its spiritual principle, modification all belong to the protection range of this patent.
