Abstract
The utility model discloses a film capacitor, comprising a leading-out end soldering lug (1), a soldering lug fastening groove (2), an internal conducting wire (3), a shell (4), an epoxy resin (5), a core (7) and a core fastening groove (8). A mandrel (6) is arranged in the center of the core (7) and located in the middle of the core fastening groove (8), the leading-out end soldering lug (1) is located in the soldering lug fastening groove (2), and the internal size of the soldering lug fastening groove (2) matches the leading-out end soldering lug (1). By using the core fastening groove and the soldering lug fastening groove to position and fix the core and the leading-out end soldering lug, the negative effects of a next working procedure on the core fixing and fastening groove positioning are prevented, and at the same time, because the interval between the core and the soldering lug does not need to be calibrated artificially, and an insulating cushion block is not used, the making time is shortened by 20% to 30%, and the product cost is reduced.
Description
Technical field
The utility model relates to capacitor, especially a kind of film capacitor of ease of assembly.
Background technology
Capacitor is one of a large amount of electronic components that use in the electronic equipment, plays at a distance from straight coupling, bypass, filtering, resonance, functions such as rectification.Characteristics such as film capacitor is a kind of of capacitor, and with respect to the capacitor of other type, it is big to have a volume low capacity, and the life-span is long.Can be divided into energy storage capacitor again according to environment for use, anti-electromagnetic interference capacitor starts capacitor, noinductive capacitor etc.Film capacitor can be divided into metallized film and foil type capacitor on manufacturing materials, but the two all has identical manufacture method and identical auxiliary material.During making, metallized film or paper tinsel film be placed on the plug reel, reel accomplish after through metal spraying, assembling, perfusion is made into finished product.But when capacitor was assembled, under the influence owing to negative factors such as the particularity of structure or the reasons of material own, installation time can account for 20%～35% of total Production Time, thereby has caused the product time of delivery long, the drawback that cost is high.
The utility model content
The purpose of the utility model is to make and in assembling process, can reduce the production time through improving the capacitor internal structure, reduces cost.
The film capacitor that the utility model provides comprises: exit weld tabs, shell, epoxy resin, fuse and inner lead.Said film capacitor also comprises: weld tabs draw-in groove and fuse draw-in groove; And the center of said fuse is provided with plug.Wherein:
Said plug is between two draw-in groove posts of said fuse draw-in groove, and the spacing of said two draw-in groove posts equals the diameter of said plug.
Said exit weld tabs is arranged in said weld tabs draw-in groove, and the inside dimension of said weld tabs draw-in groove equals the size of said exit weld tabs.
Said film capacitor comprises at least two exit weld tabs, and the quantity of said weld tabs draw-in groove equates with the quantity of said exit weld tabs.The injection moulding simultaneously of said weld tabs draw-in groove and said shell is come out, and the top edge of said weld tabs draw-in groove is lower than the top edge of said shell.
The injection moulding simultaneously of said plug draw-in groove and said shell is come out, and said plug draw-in groove top edge is lower than said shell top edge.
The useful technique effect of the utility model is: fuse center plug is placed in the plug draw-in groove; The exit weld tabs is placed in the weld tabs draw-in groove; Said plug draw-in groove and said weld tabs draw-in groove play the effect that fuse and weld tabs are fixed, located respectively, prevent that later process from producing the negative effect to fuse location and draw-in groove location.Because of not needing artificial check and correction weld tabs spacing and not using cross-over block, make Production Time shorten 20%～30% simultaneously, reduced product cost.
Description of drawings
The structural representation of the film capacitor that Fig. 1 provides for the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model specific embodiment is described.
The metallized film capacitor that the utility model provides comprises: exit weld tabs 1, weld tabs draw-in groove 2, inner lead 3, shell 4, epoxy resin 5, fuse 7, fuse draw-in groove 8; Said fuse 7 centers are provided with plug 6.Wherein, said fuse draw-in groove 8 is used for fixing said plug 6, and said weld tabs draw-in groove 2 is used for fixing said exit weld tabs 1.
Said plug 6 is arranged in said fuse draw-in groove 8, plays the positioning action to said fuse 7.
Exit weld tabs 1 is arranged in said weld tabs draw-in groove 2, is used for exit weld tabs 1 is fixed.Prevent in subsequent handling, because the change in location of the exit weld tabs 1 that other a variety of causes cause.Owing to have two exits at least in the film capacitor; The weld tabs draw-in groove 2 that has only drawn an exit weld tabs 1 among Fig. 1 and matched with it; Unshowned exit weld tabs is consistent with exit weld tabs 1 structure shown in Fig. 1, and also consistent with the weld tabs draw-in groove 2 shown in Fig. 1 with its supporting weld tabs draw-in groove.
The top edge of said fuse draw-in groove 8 is lower than the top edge of shell 4, and the intercolumniation of said fuse draw-in groove 8 equals diameter of mandrel.
The top edge of said weld tabs draw-in groove 2 is lower than the top edge of shell 4, and the size of the draw-in groove inside dimension of said weld tabs draw-in groove 2 and said exit weld tabs 1 is suitable.
Epoxy resin 5 is used to seal said film capacitor.
Through utilizing fuse draw-in groove 8 to come location mandril 6, thus can positioning core 7; Fix exit weld tabs 1 through weld tabs draw-in groove 2, prevent the negative effect of later process exit weld tabs 1 and fuse 7 location.Because of not needing artificial check and correction weld tabs spacing, need not use cross-over block simultaneously, make Production Time shorten 20%～30%, reduce product cost simultaneously.
The utility model can be used for metallic film capacitor and foil type capacitor etc.
