Embodiment
Core of the present utility model is to provide a kind of thin film capacitor, improves the pulling capacity of lead, to improve thin-film capacitor
The service life of device.
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
As depicted in figs. 1 and 2, the utility model discloses a kind of thin film capacitor, including the capacitor with zinc layers 12
The lead wire set of the electrode of element 1 and extraction capacitor element 1, wherein, at least one lead sprays with zinc layers 12 in the lead wire set
Zinc welds.Because the material of the zinc layers 12 of capacitor element 1 and spraying point is all pure zinc, the conjugation of zinc and zinc is than zinc and tin
Conjugation it is more firm.Pure zinc welding lead is sprayed, lead is just embedded in inside the environment of pure zinc, combined with capacitor element 1
To the purpose for together, reaching extraction electrode, this mode will not damage capacitor element 1, and improve capacitor element 1 with
The pulling capacity of lead.
In specific embodiment, above-mentioned lead wire set includes first be connected respectively with the zinc layers at the both ends of capacitor element
The lead 3 of lead 2 and second, and the first lead 2 and/or the second lead 3 spray zinc welding with zinc layers 12.In addition, in practice, it is right
It is also possible to that there are three leads or four leads in lead wire set, corresponding different thin film capacitor.Preferable mode in the application
It is that all leads are sprayed to zinc welding with zinc layers 12.
The first lead 2 passes through the plug 11 of capacitor element 1 in practice, and the first lead 2 passes through the mode of plug 11, can
It is convenient that walking line is entered to the first lead 2, avoid the damage to the first lead 2.
On the basis of above-mentioned technical proposal, the length of the first lead 2 is more than the length of the second lead 3.Draw due to first
The lead 3 of line 2 and second is drawn to connect external part from once end, and the distribution of electrodes of the plug 11 of thin film capacitor exists
Both ends, the first lead 2 is connected through plug 11 with distal end, and the second lead 3 is connected with the zinc layers of near-end, therefore, can be by first
