Description
Technical field
The utility model relates to the fixed cover of electrode in a kind of capacitor, and particularly a kind of environment-friendly type fixed cover matched with capacitor case, belongs to capacitor assembly technical field.
Background technology
Electric capacity is one of electronic component of a large amount of uses in electronic equipment, and be widely used in fields such as power electronics, communications service and rail transport, wherein film capacitor is because volume is little, fail safe is high, has promoted the development in capacitor technology field greatly.In prior art, the general method for making of film capacitor is on a plastic film using the very thin metal of vacuum evaporation last layer as electrode, after again electrode is overlapping from two ends with plastic films such as poly-ethyl ester, polypropylene, polystyrene or Merlon, be wound into cylindric metal film electrode, then obtain film capacitor through assembling.In the preparation process of this film capacitor, because membrane electrode carries out multilaminate coiled, if not being fixed it, membrane electrode will get loose, affect the normal use of capacitor, therefore need to design a kind of device that membrane electrode is fixed targetedly and solve the problem got loose.
Summary of the invention
For solving problems of the prior art, the utility model provides a kind of environment-friendly type fixed cover matched with capacitor case, and concrete technical scheme is as follows:
A kind of environment-friendly type fixed cover matched with capacitor case, described environment-friendly type fixed cover is made of plastics, comprise sleeve and cover plate, described cover plate is arranged on the position near sleeve upper opening, described cover plate central is provided with the through hole running through plate face, described side edge thereof is symmetrically arranged with two slotted eyes, and described sleeve edges upwards extends to form casting lug thereon near the position of slotted eye.
As the improvement of technique scheme, the position that described side edge thereof is corresponding to two slotted eyes is provided with the preformed hole running through plate face.
As the improvement of technique scheme, described sleeve has the chamfering of rounding off away from one end of casting lug thereon.
As the improvement of technique scheme, the position near cover plate in described sleeve is provided with annular protrusion.
As the improvement of technique scheme, the described cover plate back side is provided with boss, and described boss is arranged along through hole circumference, and described boss both sides have outer inclined-plane and interior inclined-plane, and described outer inclined-plane connects boss and the cover plate back side, and described interior inclined-plane connects boss and through hole.
As the improvement of technique scheme, described boss is provided with multiple bar-shaped trough, described bar-shaped trough runs through outer inclined-plane and interior inclined-plane.
In technique scheme, slotted eye is symmetricly set on side edge thereof; while ensureing that electrode outlet line passes; avoid influencing each other between two electrodes; and be both electrode outlet line had been protected near the effect of the casting lug thereon of slotted eye; can coordinate with capacitor case again, facilitate the assembling of capacitor, overall structure is adopted made of plastic simultaneously; use safety environmental protection, beneficial effect is remarkable.

Embodiment
As shown in Figure 1, the utility model provides a kind of environment-friendly type fixed cover matched with capacitor case, described environment-friendly type fixed cover is made of plastics, comprise sleeve 10 and cover plate 20, described cover plate 20 is arranged on the position near sleeve 10 upper opening, described cover plate 20 center is provided with the through hole 22 running through plate face, and described cover plate 20 edge is symmetrically arranged with two slotted eyes 21, and described sleeve 10 edge upwards extends to form casting lug thereon 11 near the position of slotted eye 21.In this technical scheme, slotted eye 21 is symmetricly set on cover plate 20 edge; while ensureing that electrode outlet line passes; avoid influencing each other between two electrodes; and be both electrode outlet line had been protected near the effect of the casting lug thereon 11 of slotted eye 21; can coordinate with capacitor case again, facilitate the assembling of capacitor.
Further, the position corresponding to two slotted eyes 21, cover plate 20 edge is provided with the preformed hole 23 running through plate face, and in this structure, the effect of preformed hole 23 adapts to some electrode outlet lines not in the situation of cover plate 20 both sides; Further, sleeve 10 has the chamfering 12 of rounding off away from one end of casting lug thereon 11, in this structure, the effect of chamfering 12, when avoiding employing right-angle structure, produces burr, thus scratch film when being inserted in sleeve 10 by the membrane electrode of rolling in fixed cover forming process; Further, the position near cover plate 20 in sleeve 10 is provided with annular protrusion 30, and the effect of annular protrusion 30 is increased the friction of membrane electrode and sleeve 10 inwall, thus restriction membrane electrode moves up and down in cylindrical shell 10.
In the above-described embodiments, cover plate 20 back side is provided with boss 40, described boss 40 is arranged along through hole 22 circumference, described boss 40 both sides have outer inclined-plane 41 and interior inclined-plane 42, and described outer inclined-plane 41 connects boss 40 and cover plate 20 back side, and described interior inclined-plane 42 connects boss 40 and through hole 22, the effect of boss 40 is kept apart at membrane electrode and sleeve 10, and interior inclined-plane 42 is connected with through hole 22, the core held and use when membrane electrode is reeled can be formed, realize fixing core; Further, boss 40 is provided with multiple bar-shaped trough 50, described bar-shaped trough 50 runs through outer inclined-plane 41 and interior inclined-plane 42, in this structure bar-shaped trough 50 act on the passage forming electrolysis liquid between outer inclined-plane 41 and interior inclined-plane 42 and pass through, be convenient to electrolyte and immerse completely in each winding layer of membrane electrode.
