Abstract

The utility model relates to a tooth shaped metallized film using a conventional capacitor material metallized film as a basic type. Outgoing line teeth are arranged at the edge of a conventional metallized film, and the teeth of the metallized film are mutually joined with the tooth joints of the metallized film, to be wound; the outgoing lines of two (a pair of) pole plates which are led out on the same sectional plane are realized, and the capacitor of the outgoing line of the signal sectional plane is realized; the utility model can fit with the conventional metallized film to be used, to manufacture the three pole plate capacitor and the outgoing line, to realize the requirement of the outgoing line of multi-pole plate capacitor; thereby the manufacturing process of the multi-pole plate capacitor is realized, to meet the requirements of diversified development of the capacitor and the three-phase electrical equipment.

Description

The profile of tooth metalized film

The utility model belongs to capacitor material, especially can be adapted to the profile of tooth metalized film of polylith plate capacitors lead-out wire.

Metalized film is the essential material that capacitor is produced, generation along with varied electrical equipment, the development of capacitor is also along with variation, from the energy storage capacitor to the compensation condenser, and the three-in-one three-phase compensation capacitor of single-phase compensation condenser, two plate capacitors combinations etc.But present its coiling of known metalized film can not be drawn the lead-out wire of two (a pair of) pole plates during for capacitor plate on same cross section, it can only draw an end lead-out wire of capacitor, on another relative cross section, draw another root terminals, therefore it can only adapt to the capacitor of present two pole plates, and can not satisfy the demand of other capacitor, as: the needs of a plurality of plate capacitors, limited the development of capacitor and the demand of three-phase electric apparatus equipment.

It is the profile of tooth metalized film of fundamental mode with the common metal film that the purpose of this utility model provides a kind of, and it can not only be adapted to the capacitor of two pole plates and can be applicable to the needs of a plurality of plate capacitors; Can on same cross section, draw the lead-out wire of two (a pair of) pole plates during as capacitor plate.

The utility model is that the edge at metalized film sets up the lead-in wire tooth, the height of tooth and metalized film stay the hem width degree basic identical; When producing if the tooth of metalized film mutually on the slot of metalized film, carry out coiling, can achieve the above object; Because it is overlapping that its metal-toothed does not have, it is to draw the lead-in wire tooth at corresponding metalized film slot place; Thereby can be implemented in the lead-out wire of drawing two (a pair of) pole plates on the same cross section, reach the lead-out wire demand of a plurality of plate capacitors

Owing on the metalized film edge, be provided with the lead-out wire tooth, thereby can be implemented in the lead-out wire of drawing two (a pair of) pole plates on the same cross section, realize single cross section lead-out wire capacitor, can realize the production technology of a plurality of plate capacitors.

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

Fig. 1: be profile of tooth metallized film structure schematic diagram; A does not stay heel teeth shape metalized film; B is that band stays heel teeth shape metalized film.

Fig. 2: be profile of tooth metallization embodiment schematic diagram.

Fig. 3: be the capacitor schematic cross-section of equidistant profile of tooth metalized film coiling.

Fig. 4: be the capacitor schematic cross-section of gradual change profile of tooth metalized film coiling.

In the drawings: 1. metal; 2. medium; 3. metal lead wire tooth; 4. slot; 5. medium stays the limit; L. metal lead wire space width.

Can find out that in Figure 1A it is not stay heel teeth shape metalized film, because it does not stay the limit can only be suitable for two plate capacitors are drawn two (a pair of) pole plates on same cross section lead-out wire.Find out that in Figure 1B it is to have the profile of tooth metalized film that medium stays limit (5), it can be used the lead-out wire of making three plate capacitors with the common metal film, realizes the manufacturing process of a plurality of plate capacitors.

In the embodiment shown in Figure 2, overlapping two profile of tooth metalized films wanting coiling, both its metal-toothed (3) had been placed on the centre of two corresponding profile of tooth metalized film slots (4), to guarantee the distance of two pole plate lead-out wires, make it to be difficult for short circuit, realize the manufacturing of single cross section lead-out wire capacitor; On this basis, again the metalized film of the 3rd routine stayed the limit end, form three pole plates towards the overlapping placement of band metal lead wire increment, it just can draw the terminals of the 3rd pole plate at the other end (not with the metal increment) after carrying out coiling, thereby has realized the manufacturing of a plurality of plate capacitors.

Fig. 3 is L coiling when equidistant, the situation that metal lead wire tooth (3) distributes because the metal lead wire tooth is equidistant, when producing capacitor be by minor diameter gradually coiling to the major diameter of desired volume; Because of other metal-toothed at capacitor end surface be distributed as spiral-shaped, thereby the capacitor that it can only be adapted to that pitch of the laps quantity is few, the pitch of the laps girth is long, thereby it can not satisfy the demand that capacitor is produced; Therefore produce the profile of tooth metalized film of L gradual change: the spacing of L is the girth decision by the every pitch of the laps of capacitor; The L spacing that changes along with the pitch of the laps perimeter change is the gradual change tooth film of present technique; Can produce the distributed architecture of metal lead wire tooth (3) shown in Figure 4 after its coiling; On this structural section, the metal lead wire tooth of two pole plates, but 180 operating spaces of spending are all arranged separately, thus it is convenient to drawing of pole plate, can adapt to polytype and specification capacitor and on single cross section, draw the terminals of two pole plates, but its production technology is than equidistant tooth film complexity.Profile of tooth metalized film production technology can be with reference to the safety anti-explosive film.
