The drawings of the present invention are for illustrative purposes only and are not drawn to scale. The following embodiments will further explain the related art of the present invention in detail, but the disclosure is not intended to limit the scope of the present invention.
[ first embodiment ]
Referring to fig. 1 to 3, a first embodiment of the present invention provides a capacitor package structure Z without a negative conductive foil, which includes: a winding component 1, a package component 2 and a conductive component 3, wherein the capacitor package structure Z can be a winding type capacitor package structure.
First, referring to fig. 1 and 2, the roll-to-roll assembly 1 includes a roll-to-roll positive conductive foil 11 and a roll-to-roll separator 12 cooperating with the roll-to-roll positive conductive foil 11. That is, as shown in fig. 1, the wound positive electrode conductive foil piece 11 and the wound separator paper 12 are wound from a "flat shape" into a "wound shape", and the wound positive electrode conductive foil piece 11 and the wound separator paper 12 are simultaneously spirally wound together to constitute the wound module 1. For example, as shown in fig. 2, the roll-type separator paper 12 can be impregnated with the conductive polymer liquid, so that a plurality of conductive polymer materials M1 can be absorbed inside the roll-type separator paper 12, but the roll-type separator paper 12 of the present invention is not limited to the example shown in fig. 2.
As shown in fig. 1 and 3, the reel-type module 1 is housed inside the package 2. For example, as shown in fig. 3, the package assembly 2 includes a capacitor casing structure 21 (e.g., an aluminum casing or other metal casing) and a bottom end sealing structure 22. In addition, the capacitor casing structure 21 has an accommodating space 210 for accommodating the winding assembly 1, and the bottom end sealing structure 22 is disposed at the bottom end of the capacitor casing structure 21 to seal the accommodating space 210. However, the package assembly 2 of the present invention is not limited to the example shown in fig. 3. That is, the package assembly 2 may be a package body made of any insulating material (e.g., epoxy or silicone).
Furthermore, as shown in fig. 1 and fig. 3, the conductive element 3 includes a first conductive pin 31 electrically contacting the wound positive conductive foil 11 and a second conductive pin 32 electrically contacting the wound separator paper 12. In other words, as shown in fig. 1, the first embodiment of the present invention can provide a roll-to-roll assembly 1 without a negative conductive foil, the roll-to-roll assembly 1 and a conductive assembly 3 are electrically matched with each other, and the roll-to-roll assembly 1 includes a roll-to-roll positive conductive foil 11 and a roll-to-roll separator 12. In addition, the wound positive electrode conductive foil member 11 and the wound separator paper 12 are fitted to each other, and a plurality of conductive materials CM (shown in fig. 2) are adsorbed inside the wound separator paper 12. In addition, a first conductive pin 31 and a second conductive pin 32 of the conductive assembly 3 are respectively in electrical contact with the wound positive conductive foil 11 and the wound separator paper 12, and the wound positive conductive foil 11 and the wound separator paper 12 are simultaneously spirally wound together to form the wound assembly 1.
More specifically, as shown in fig. 1 and fig. 3, the first conductive pin 31 has a first embedded portion 311 that is coated inside the package assembly 2 and electrically contacts the wound positive conductive foil 11, and a first exposed portion 312 that is connected to the first embedded portion 311 and exposed outside the package assembly 2, and the second conductive pin 32 has a second embedded portion 321 that is coated inside the package assembly 2 and electrically contacts the wound release paper 12, and a second exposed portion 322 that is connected to the second embedded portion 321 and exposed outside the package assembly 2.
More specifically, as shown in fig. 3, the first embedded portion 311 has a first embedded section 3111 inserted into the winding assembly 1 and fixed on the winding positive electrode conductive foil 11, and a first exposed section 3112 connected to the first embedded section 3111 and exposed outside the winding assembly 1. In addition, the second embedded portion 321 has a second embedded section 3211 inserted into the interior of the roll-to-roll assembly 1 and fixed on the roll-to-roll insulation paper 12, and a second exposed section 3212 connected to the second embedded section 3211 and exposed to the exterior of the roll-to-roll assembly 1.
It should be noted that, referring to fig. 4, in the first embodiment of the present invention, besides the interior of the roll-type release paper 12 can absorb a plurality of conductive polymer materials M1, the roll-type release paper 12 can also absorb a plurality of conductive silver glue materials M2 or a plurality of conductive carbon glue materials M3 by immersing the conductive silver glue liquid or the conductive carbon glue liquid in the roll-type release paper 12. Therefore, the invention can reduce the loss factor (DF) of the capacitor packaging structure Z by using a plurality of conductive silver adhesive materials M2 or a plurality of conductive carbon adhesive materials M3. That is, according to different usage requirements, as shown in fig. 2, only the plurality of conductive polymer materials M1 can be adsorbed inside the roll type release paper 12, or as shown in fig. 4, the plurality of conductive polymer materials M1 and the plurality of conductive silver paste materials M2 (or the plurality of conductive carbon paste materials M3) can be adsorbed inside the roll type release paper 12 at the same time.
For example, as shown in fig. 2, when only a plurality of conductive polymer materials M1 are adsorbed inside the roll-type separator paper 12, the roll-type separator paper 12 having a plurality of conductive polymer materials M1 adsorbed inside can be used as a kind of negative electrode conductive paper. As shown in fig. 4, when the roll type isolation paper 12 can adsorb a plurality of conductive polymer materials M1 and a plurality of conductive silver colloid materials M2 (or a plurality of conductive carbon colloid materials M3) at the same time, the roll type isolation paper 12 having a plurality of conductive polymer materials M1 and a plurality of conductive silver colloid materials M2 (or a plurality of conductive carbon colloid materials M3) adsorbed therein can be used not only as a negative conductive paper, but also to reduce the loss factor of the capacitor package structure Z.
As mentioned above, the conductive materials CM that the roll-type separator 12 can absorb may be conductive polymer materials M1, conductive silver glue materials M2, or conductive carbon glue materials M3, but the conductive materials CM are not limited to the above examples, and any conductive material can be used as long as the roll-type separator 12 can be made into a negative conductive paper. That is, the first embodiment of the present invention can provide a capacitor package structure Z that does not require a negative conductive foil, including: a reel-type device 1, a package device 2 and a conductive device 3. The roll-to-roll assembly 1 includes a roll-to-roll positive conductive foil 11 and a roll-to-roll separator 12 cooperating with the roll-to-roll positive conductive foil 11, and a plurality of conductive materials CM are adsorbed inside the roll-to-roll separator 12. The roll module 1 is housed inside the package module 2. The conductive element 3 includes a first conductive pin 31 electrically contacting the wound positive conductive foil 11 and a second conductive pin 32 electrically contacting the wound separator paper 12.
It should be noted that the capacitor package structure Z disclosed in fig. 3 can also be replaced by the capacitor package structure Z disclosed in fig. 5. The capacitor package structure Z disclosed in fig. 5 differs from the capacitor package structure Z disclosed in fig. 3 in that: the first exposed portion 312 of the first conductive pin 31 and the second exposed portion 322 of the second conductive pin 32 of the capacitor package structure Z disclosed in fig. 5 are bent by about 90 degrees in two opposite directions.
It is particularly noted that, as shown in fig. 1, since the wound assembly 1 of the capacitor packaging structure Z of the present invention can only adopt the wound positive electrode conductive foil 11 and the wound separator paper 12 which are wound and matched together, and omit the use of the wound negative electrode conductive foil, it will help to increase the capacitance which can be provided by the capacitor packaging structure Z when the volume of the capacitor packaging structure Z is not changed, and it will help to reduce the volume of the capacitor packaging structure Z when the capacitance of the capacitor packaging structure Z is not changed. Moreover, since the capacitor package structure Z of the present invention can omit the use of the wound cathode conductive foil, the total capacitance of the capacitor package structure Z can be completely determined by the design and size of the wound anode conductive foil 11.
[ second embodiment ]
Referring to fig. 6, a second embodiment of the present invention provides a capacitor package structure Z without a negative conductive foil, which includes: a reel-type device 1, a package device 2 and a conductive device 3. The conductive element 3 includes a first conductive pin 31 electrically contacting the coiled positive conductive foil 11 and a second conductive pin 32 electrically contacting the coiled separator paper 12, the first conductive pin 31 has a first embedded portion 311 and a first exposed portion 312, and the second conductive pin 32 has a second embedded portion 321 and a second exposed portion 322. In addition, the first embedded portion 311 has a first embedded section 3111 inserted into the winding assembly 1 and fixed on the winding positive electrode conductive foil 11, and a first exposed section 3112 connected to the first embedded section 3111 and exposed outside the winding assembly 1.
As can be seen from a comparison between fig. 6 and fig. 3, the greatest difference between the second embodiment of the present invention and the first embodiment is: in the second embodiment, the second embedded portion 321 is fixed on the inner surface of the capacitor casing structure 21 and exposed outside the wound package 1, and the second embedded portion 321 has a contact section 3213 detachably contacting the wound insulation paper 12 and a non-contact section 3214 connected to the contact section 3213 and separated from the wound insulation paper 12 without contact. That is, the second conductive pin 32 of the conductive element 3 can be fixed on the inner surface of the capacitor housing structure 21 in advance. When the roll-to-roll package 1 is placed in the accommodating space 210 of the package 2, the contact segment 3213 of the second embedded portion 321 of the second conductive pin 32 can directly electrically contact the roll-to-roll separator 12.
[ third embodiment ]
Referring to fig. 7 to 9, a third embodiment of the present invention provides a roll-to-roll assembly 1 without a negative conductive foil, the roll-to-roll assembly 1 and a conductive assembly 3 are electrically matched, and the roll-to-roll assembly 1 includes a roll-to-roll positive conductive foil 11 and a roll-to-roll separator 12. In addition, a first conductive pin 31 and a second conductive pin 32 of the conductive assembly 3 are respectively in electrical contact with the wound positive conductive foil 11 and the wound separator paper 12, and the wound positive conductive foil 11 and the wound separator paper 12 are simultaneously spirally wound together to form the wound assembly 1.
Further, as shown in fig. 7, the wound positive electrode conductive foil 11 has a first insulating cover layer 110 for covering the first buried section 3111 of the first buried portion 311, and the first buried section 3111 of the first buried portion 311 and the wound separator paper 12 can be separated and insulated from each other by the covering of the first insulating cover layer 110.

The capacitor packaging structure Z and the winding assembly 1 thereof without the negative conductive foil provided by the technical scheme of the invention have the beneficial effects that the winding assembly 1 comprises the winding positive conductive foil 11 and the winding type isolation paper 12 matched with the winding positive conductive foil 11, and the winding type isolation paper 12 is absorbed with a plurality of conductive materials CM inside, so that the winding type isolation paper 12 absorbed with a plurality of conductive high molecular materials M1 inside can be used as a negative conductive paper.
In addition, when the roll-type separator paper 12 can simultaneously adsorb a plurality of conductive polymer materials M1 and a plurality of conductive silver colloid materials M2 (or a plurality of conductive carbon colloid materials M3), the roll-type separator paper 12 having a plurality of conductive polymer materials M1 and a plurality of conductive silver colloid materials M2 (or a plurality of conductive carbon colloid materials M3) adsorbed therein can be used not only as a negative conductive paper, but also to reduce the loss factor of the capacitor package structure Z.
Moreover, since the capacitor package structure Z of the present invention can omit the use of the wound negative conductive foil, the capacitor package structure Z can help to increase the capacitance that the capacitor package structure Z can provide without changing the volume of the capacitor package structure Z, and can help to reduce the volume of the capacitor package structure Z without changing the capacitance of the capacitor package structure Z. In addition, since the capacitor package structure Z of the present invention can omit the use of the wound negative conductive foil, the total capacitance of the capacitor package structure Z can be completely determined by the design and size of the wound positive conductive foil 11.
The disclosure is only a preferred embodiment of the invention and should not be taken as limiting the scope of the invention, so that the invention is not limited by the disclosure of the invention.
